PVC compound stabilizer

Pure PVC resin is extremely sensitive to heat, when the heating temperature reaches 90Y: more, the thermal decomposition occurs slight reaction when the reaction temperature rose to 120C after decomposition intensified in 150C, 10 分钟, PVC resin, the original white gradually turns yellow - red

- Brown - black. PVC resin decomposition process is due to de-HCL reaction caused a chain reaction leading to macromolecules strand breaks. Prevent the thermal stability of PVC thermal decomposition mechanism is through the following aspects to achieve.
(1) by thermal decomposition of PVC capture HCl, to prevent degradation of the catalytic HCl. Click mechanisms lead salt major role, in addition to metal soap, organic tin, pho sphorous and other lipids and epoxy.
(2) replacement of reactive allylic chlorine atom. Metal soap, phosphorous lipids and organic tin can click here Mechanism effect.
(3) react with free radicals to terminate radical reactions. Organic tin and phosphorous mechanism of lipid Click role.
(4) and conjugated double bond, inhibiting the growth of conjugated chain. Organotin mechanism with epoxy Click role.
(5) peroxide decomposition, reducing the number of free radicals. Organic tin and phosphite Click Mechanism effect.
(6) de HCl passivating effect of a catalytic metal ions.
   With a stabilizer according to several different mechanisms for thermal stability purposes.
   Heat stabilizers Varieties - composite stabilizer
   Composite stabilizer can be divided into the following categories:
1 Liquid Ba-Zn composite stabilizer are generally pale yellow to yellow-brown oily liquid, specific gravity of 1.0-1. 1 at room temperature, good heat resistance, pollution from sulfur, with an epoxy plasticizer and used to increase the stabilizing effect, it activation of the blowing agent.
2 liquid calcium zinc composite stabilizer nontoxic liquid calcium zinc stabilizers main ingredients are calcium stearate, castor oil, calcium, zinc stearate, castor oil, zinc and epoxy soybean oil, ultraviolet absorber. Hugh liquid calcium zinc stabilizers are generally used more soluble in organic

Solvent is an aliphatic carbon number of less fat calcium and zinc. Because of different compositions, varied in nature, usually pale yellow to yellow clear oily liquid at room temperature under a specific gravity of 1.0 to 1.05. It is non-toxic PVC stabilizer , mainly used for food packaging films, containers bubble people

Artificial leather stabilizer.
3. Liquid and liquid barium cadmium, barium cadmium zinc composite stabilizer, such composite stabilizer is mainly used for the processing of soft PVC products, the basic components include: (a) barium salt - can be alkylphenols barium, 2 - ethylhexanoic acid, barium, barium laurate (powder lamination), benzoic acid and substituted

Benzoic acid, barium and barium neodecanoate. Barium salt complexes accounted for 6-7%, ie cadmium salts ratio is around 2:1-32 (with metal in mind that weight percent, the same below). (2) cadmium salts - can be 2 - ethylhexanoic acid cadmium, cadmium lauric acid, oleic acid cadmium, phenyl and substituted benzoic acid

Cadmium, cadmium naphthenate, neodecanoate, and cadmium. Cadmium salt complexes about 3-4%. (3) zinc - can be 2 - ethylhexyl zinc, zinc laurate (powder lamination), zinc naphthenate, zinc neodecanoate, benzoic acid and substituted benzoic acid and zinc. Accounts for the composite zinc

0.5-1%. (4) phosphite - may be triphenyl phosphite, diphenyl phosphite, an octyl diphenyl phosphite, a decyl phosphite, tris (nonylphenyl), etc. In the phosphite complexes about 15-20% (by weight), as a chelating agent. (5) Other - including a small amount of

2,6 - t-butyl-p-cresol, bisphenol A, nonylphenol and other phenolic antioxidants and ultraviolet absorbers, and a liquid paraffin, white oil, diesel oil, mineral oil, spindle oil as solvent, and the need Add a small amount of antifoaming agent such as higher alcohols.
   Liquid barium cadmium zinc composite stabilizer because different composition, properties are also different. But is generally pale yellow to yellow clear liquid, specific gravity 0.95-1.02 at room temperature, the viscosity of less than 100 cps, freezing point at -15 ℃ or so. Liquid barium cadmium and liquid barium cadmium zinc are similar to each

Excellent thermal, light stability, initial coloration is small, good transparency and color stability. Their stabilizing effect than solid composit e soaps, therefore, may reduce the amount of, usually 2-3 parts, the dust does not occur poisoning, and completely dissolved in the plasticizer generally have

Good dispersion, the precipitation tendency of small. Wherein the liquid barium cadmium zinc early color than the liquid barium cadmium smaller.
4 lead salt composite stabilizer good thermal stability, has been widely used, but small lead salt powder, ingredients and mixed in its dust is inhaled can cause lead poisoning, for which they have developed a new type of scientific and technical personnel The composite lead salt heat stabilizer. This compound additive

Reaction technique using a symbiosis of the three salts, di-salt and the metal soap in the reaction system in the nascent grain size and various lubricants be mixed to ensure the PVC heat stabilizer system in the fully dispersed, and because of the lubricating agent of melting gr anular, but also to avoid

A result of lead poisoning caused by dust. Inclusive of lead salt stabilizer compound required processing heat stabilizer component and a lubricant component, known as a full package heat stabilizer. It has the following advantages: (1) compound heat stabilizer various components can be obtained in the course of production

Sufficiently mixed with the resins greatly improved the uniformity of dispersion. (2) mixing formula, simplified measurement frequency, to reduce the probability and the resulting measurement error caused by the loss. (3) a simple supply and reserve materials, is conducive to production and quality management.

(4) provides the possibility of clean production of products, improving production conditions.
    Composite stabilizer security issues
    PVC compound stabilizer security issue has been more and more people s attention. PVC compound stabilizer securit y should be three aspects to consider, first, the safety of using the processing of raw materials, the second is the user s security and the third is the safety of waste on the environment. Plus

Workers safety protection may be liquefied by stabilizing agent, paste technology, granulation and other measures to solve them. , Security protection for the user, can be prepared by a stabilizer or a reactive high molecular weight stabilizers to improve its resistance to pumping, but taking into account the effect of stabilizing the molecule

Class of chemical reactions, the above method is not the most appropriate method, the best method is still used high-security stabilizers. Stabilizer is selected, the stabilization process must also be considered in the resin and stabilizing agent, or stabilizers react with each other chemicals generated

Security.
From a variety of security stabilizers see, cadmium stabilizers in the near future will be di scontinued. But a slow process, one of the reasons is that most in the use of cadmium stabilizers when costs are increased by 10% -20%, and cadmium-based stabilizers can not be common to a wide range

The PVC compound. Such as processing a narrow range, but also often need to use auxiliary stabilizer compensate for its performance deficiencies. Now cadmium stabilizers performance has reached a performance of cadmium stabilizers. Calcium zinc stabilizers have been developed rapidly. And in powder, paste and liquid, and

Standard and non-toxic level for sale, second-generation calcium zinc stabilizer in food and pharmaceutical packaging has been replaced by methyl tin tin and zinc base.
Lead stabilizers set its extraction resistance is small, so the use of security when not a problem, but there are security issues harm the environment. Because lead-based stabilizers, low cost, high efficiency, many companies are using this, along with non-lead PVC comp ound stabilizer development, lead salts being no

Environmental toxicity replaced stabilizer. As many countries ban lead, lead-based stabilizers are withdrawn from the market
In short, the composite heat stabilizer help scale production, lead salt heat stabilizer for the development of a new direction. Lead salt stabilizer compound is an important indicator of lead content, current production of lead lead salt stabilizer compound is generally 20% -60%; in PVC plastic door

Window profile production on the amount of 3.5-6 parts

iron ore flotation machine flotation reagent adjusting agent for pulp importance

Flotation machine manufacturers specializing in the production machinery oil Yu sent a strong technical force, preferential and flexible sales policy, lifelong commitment to service, our products sell well throughout the country, are very popular. Professional flotation machine manufacturer, specializing in manufacturing, Yu hair dressing equipment plant please feel free to consult us on pulp flotation machine modifier importance of flotation machine is an important mining equipment, flotation machine by a V-belt drive motor driven impeller rotation, centrifugal vacuum formed, on the one hand inhalation of sufficient air and slurry mixture, while stirring the slurry with drugs, while refined foam, mineral adhesive foam on top of the surface and then float to the slurry to form miner alized bubbles. Ram height adjustment, control surface, useful froth scraped by the scraper. Magnet Tube

Large-scale mines in the flotation machine adjustment process in order to strengthen the role of the test, and the pulp surface of a variety of mineral components to be adjusted simultaneously, often used in conjunction modifier, flotation equipment specialists using several adjusting agent in the pulp of reaction product, in order to obtain good selectivity. Hydrophilic colloidal form in the mineral surface adsorption, hydrophilic mineral surfaces. Flotation of the polymer compounds used in practice in such a manner the main effect. For natural hydrophobic minerals such as molybdenite, talc, starch and other main type organic polymer molecule inhibition. Flotation equipment experts most of these organic molecules adsorb moisture expansion, by electrostatic attraction, hydrogen bonding or molecular forces adh ere to the mineral surface, the formation of colloidal hydrophilic membrane, resulting in mineral suppression.

Mining flotation machine operating adsorption layer on the role of intergranular Magnetic Head Pulley

Mining flotation machine operating adsorption layer Effect on intergranular three were listed as follows:

An adsorption layer on the electrostatic interactions between particles impact. Mining flotation machine work when the adsorbate charge, it is adsorbed on the particle surface, the surface potential can be changed directly affect electrostatic energy; neutral adsorbate although not directly affect the surface charge condition, but the impact of double-layer structure .

Second, the interaction energy of molecular adsorption layer effects. When the thickness of the particle surface must be considered molecular adsorption layer intergranular interaction energy between the impact and the adsorption material, adsorption material and molecular interaction energy between the particles. n52 neodymium magnets

Third, the spatial effects or steric effect. Process mining flotation machine operation when the two particles contact the adsorption layer, can generate the following several functions: (1) the adsorption layer is in contact with each other, may affect the adsorption equilibrium, causing the increase of adsorption or desorption. Because the adsorption process usually results in lower free energy, therefore, increase the amount of adsorption results in a surface to attract, results in a surface off the Annex exclusion. (2), contact the adsorption layer, the adsorption layer may cause the mutual compression adsorbate, the adsorbate free arrangement in space, be further limited. Flotation means arranged in such a restriction reduced the degree of disorder, or entropy values ​​decrease, the system free energy increases, resulting in rejection of potential energy. Such action is called spatial effects or steric effect. (3), the adsorption layer structure is loose, the adsorbate may be interspersed with each other, so that the concentration of the adsorbate chain intergranular increase. When the role of the media and the chain is strong, chain interspersed between the chains must first rule out the media, causing an increase in system free energy, potential energy repulsion between particles, in which case the adsorbed layer interspersed impossible; when the medium and The role of weaker chains chain effect, the chain interspersed cause system free energy decreases, so that intergranular produce to attract potential that such action causes the adsorbed layer overlap each other in the flotation process for the job hydrophilic minerals, in addition to with starch, dextrin and other non-ionic poly mer, the polymer often used dissociative compounds, such as tannin, lignin, cellulose, etc., are the nature of the mineral surface, depending on the type of mineral and polymer nature, still mainly electrostatic attraction and hydrogen bond, chemical adsorption can occur, for example, tannin in calcite, dolomite, calcium and magnesium minerals tables for chemical adsorption. Since these hydrophilic colloidal polymer adsorption to mineral surface more hydrophilic, even pre-adsorbed on the mineral surface collector, may also be hydrophilic macromolecules collector cover shield the hydrophobic effect.

Mining flotation machine water moisture level standards

Mining industry flotation beneficiation flotation machine is the necessary equipment, and its flotation process requires a lot of indicators, such as hydrophobicity, can float, hydrophilicity, the most important is water wetness.

Long-term research trials introduces mining flotation machine wetting contact angle and phase quantitative relationship between the interfacial force. Therefore, anything that can have an impact on the interfacial tension of the factors that we can count on a solid surface wettability display effect. For example, various organic and inorganic flotation agent, and each of the active ions in aqueous solution can affect the interfacial tension. Description mine flotation tank wetting contact angle higher the value, the solid surface is moist and the lower the degree of Nirvana. It can be said that the stronger the hydrophobic solid surface, on the contrary, the smaller the wetting contact angle, the solid surface is wetted with water the higher the level, the hydrophilicity of the surface of this solid stronger.

Mineral surface hydrophobic stronger pull of the mineral particles Flotability better, on the contrary, hydrophilic mineral surface, the stronger the pull of mineral particles can float the worse. This means that, as long as the measured liquid surface tension and contact angle values, you can determine the level of mineral floatability. In fact, this is the ideal conditions of mathematical reasoning. So far, the only location in the static condition of the contact angles measured values. In addition, strictly speaking, the interfacial tension of the solid and interfacial energy are not equal. Common minerals in the water interfacial tension to the digital interface is much lower than that. Therefore, usually measured under static conditions as the evaluation value of the contact angle of the mineral surface wettability index.

application and adaptation of iron ore magnetic separator to solve common problems

 Magnetic separator works: 0.04-5 mm ore into the hopper, through vibration motor vibration cloth, a quantity by hand wheel for precise adjustment. By dragging the magnetic roller speed motor, the speed of the speed to be adjusted through the governor table, you can control the output of iron ore magnetic separator and concentrate grade. Is fed by mineral particles on the magnetic roller conveyor sorting, because hematite mineral particles magnetic, strong magnetic field immediately adsorbed on the magnetic roller, while the gangue grains (miscellaneous stone, sand) the absence of a magnetic (magnetic weak), magnetic roller it does not produce magnetic suction.

      In order to enable users to play a greater level of magnetic separation equipment production efficiency, Yu Fa Machinery equipment and technical personnel combined with its own characteristics of its iron ore magnetic separator do a bit of common cause failure analysis: Magnetic Head Pulley

     (1) iron ore magnetic separator machine motor overheating and its sound is not normal.
The reason: a) poor or badly worn bearing lubrication; 2) fan leaves fall off or wear; 3) switch line is bad, or disconnection run single phase; 4) voltage is too low.

     (2) iron ore magnetic separator in operation between the sound is not normal, cylinder stuck by an obstacle, even the drum does not rotate, the bottom box fibrillation.
The reason is often the bottom box of the object to be stuck, then there are magnetic blocks off, so that rattled the cylinder, cylinder serious cause skin scratched. This time should be shut down for maintenance, troubleshooting

     (3) iron ore magnetic separator reducer overheating
The reason: a) insufficient oil or oily bad; 2) gear and worm wear off very, bad, or engagement; 3) bearing lubrication bad or badly worn.
Magnet Tube
     With the rotation of the magnetic roller, mineral particles has been sucked in the magnetic roller, while the gangue grains in the magnetic roller to the front end position is thrown out in front of the spacer plate mine (mine plates separated by changing the angle resizable concentrate grade), mineral particles continue to be taken off the magnetic roller automatically fall into one volume anthology concentrate ore bucket to collect the finished product. Iron ore magnetic separator have been around for over half a century, has also been a number of improvements. Currently, iron ore magnetic separator has gradually replaced the traditional equipment, has been widely applied to the gravel production industries. The emergence of iron ore magnetic separator, greatly improving production efficiency, to help businesses rapidly.

     Iron ore magnetic separator uses: magnetic field intensity magnetic separator equipment up 14500Gs, a large magnetic field gradient, less power consumption, stable performance. The equipment used for low-grade hematite weak magnetic separation can be one-time increase 5-15 grade hematite, a good solution is not always low-grade hematite into the furnace smelting, sales difficult problem, found a way out for the low-grade ore, can produce considerable economic benefits. The device is a high return on investment is less investment and quick a good project.
     
   &nbs p;  Since the fall of the magnetic roller entrained gangue also some weaker magnetic mineral particles, they will continue into the next magnetic roller magnetic separation, magnetic separation of mineral particles into two finished anthology ore bucket collection for the finished product, was thrown out of the gangue by tailings discharge port, thus magnetic separation process ends. Because ore gangue been abandoned, so that the grade of hematite improved. The entire device power consumption is only about 4KW, magnetic input costs are quite low. n52 neodymium magnets

      With advanced equipment, iron ore magnetic separator technology development, high technology products are ready to come out. The development of iron ore magnetic separator has come to a white-hot stage whether a higher level, you need a good policy job, so in order to be able to be made within a limited time novel innovation is essential. Iron ore magnetic separator using our newly developed with high magnetic permeability and magnetic energy NdFeB permanent magnetic material magnetizing as magnetic source, and sorting objects according to the magnetic induction characteristics and actual operation analysis, scientific design, careful made of.

PVC has good chemical resistance, mechanical properties and electrical properties, but its resistance to heat and light stability. By processing the modified PVC plastic, can be widely used to make storage blood bags, blood bags and blood catheters, artificial peritoneum, artificial urinary bag artificial lung, cardiac catheterization and artificial heart and other products.

PVC gl ass transition temperature (Tg) is higher, the hardness of the material, the molding process difficult. Thus, the ships are added to the PVC resin, plasticizer and other additives. At present, still in the processing phthalate, dioctyl phthalate (DOP) as a primary plasticizer [1]. DOP is a low molecular weight substances, easy migration precipitation. DOP plasticized PVC for medical tubing or container, the DOP easy precipitation mixed with liquid or blood will lead to enter the body of the DOP with liquid or blood. In order to protect the health and safety of PVC medical plastic abroad are developing toxicity lower than the DOP, the migration precipitation DOP small new plasticizer, including good health citric acid esters, higher molar mass polyester class and other polymeric plasticizer.surgical sutures types
