The main reason heat stabilizer for shoes heat discoloration
Thermal stabilizers should preferably absorb both HCL, to eliminate the
active site, the addition of a conjugated polyene chain, carbenium salt
damage, etc. to prevent auto-oxidation, which does not produce the product
of the catalytic degradation of PVC. The Plastic impact modifier actual heat stabilizers have
different functions due to exhibit different thermal stability
characteristics, can be divided into early-type, long-term, intermediate-
and versatile four.
Shandong Zouping, this piece of land has been brought up generation phase
of Fan, its famous through the ages "first and worry about the world,
after the world music", popular for generations lips.
A) cadmium, zinc soap is typical of early-type heat stabilizers, can
quickly absorb HCL, and effectively substituted with carboxylate PVC
unstable chlorine atom in the catalytic chain Cd, Zn, thereby effectively
suppressing early degradation and coloring , but because of the
consumption of fast and transformation products CdC12, ZnC12, but also off
the HCL efficient catalyst PVC, PVC and Chlorinated paraffin thus lead to the degradation of
the material suddenly vicious black, so poor long-term thermal stability.
2) barium, calcium soaps are typically long-term thermal stabilizers,
absorption HCL function only and therefore can not inhibit coloring PVC,
but the conversion product BaC12, CaC12 do not have catalytic activity,
does not cause a sudden black PVC, long-term heat stability better.
3) fatty acids, organic tin are intermediate, both absorption HCL, can
effectively replace with carboxylate unstable chlorine atoms PVC chain,
and transformation products do not have catalytic activity.
4) mercaptan organotin it has versatile Polyethylene wax features, while a variety of
mechanisms can stabilize PVC, transformation products do not have
catalytic activity, and therefore both excellent initial and long-term
thermal stability effect.

Some of the major components of plastic lubricant
We are not a pure plastic material generally used , which is made of material prepared by a number . Wherein the polymer (or synthetic resin ) is the main component of plastic, in addition , in order to improve the performance of plastics , but also add a variety of auxiliary materials such as fillers , plasticizers , lubricants , stabilizers in the polymer, coloring agents , in order to become a good performance plastics.
A synthetic resin, synthetic resin is a main component of plastic, the plastic content is generally 40% to 100%. As WSD aluminium stearate the content of large, but the nature of the resin often determines the nature of plastic, so people often plastic resin as a synonym . For example, polyvinyl chloride resin and PVC , phenolic resin and phenolic confused. In fact, resins and plastics are two different concepts. Original polymer resin is a raw , it is not only used to make plastics , but also coatings, adhesives and synthetic materials. In addition to the very small number of plastic resin containing 100% , the majority of plastics , in addition to the main component of the resin , but also need to add other substances.
2 , also known as filler of fillers , which can improve the strength and resistance to heat , and cost . E.g. a phenolic resin is added after the flour can greatly reduce costs, the most inexpensive one phenolic plastics , as well as significantly improved mechanical strength. The filler may be divided into two types of inorganic fillers and organic fillers , such as wood flour former , rags , paper and various textile fibers , which, as glass fibers, diatomaceous earth , asbestos , carbon black and the like.
3 , a plasticizer , and a plasticizer to increase the flexibility of the plastic plasticity , reducing brittleness , so that the plastic processibility . Plasticizers are generally miscible with the resin , non-toxic , odorless, light, heat stable, high boiling point organic compounds, the most commonly used phthalates . E.g., the production of PVC , plasticizer , if adding more soft PVC can be obtained , if not add plasticizers or less (the amount of < 10% ) , then a rigid PVC .
4 , a stabilizer to prevent the WSD Chrolinated polyethylene synthetic resin by the action of light and heat during use in the processing and decomposition and destruction, extended service life , to add the stabilizer in plastics . Commonly used are stearates, such as epoxy resin .
5 , plastic colorant colorants can have a variety of bright , beautiful colors. The organic dyes and inorganic pigments used as a colorant . Specialty Plastics
6 , the lubricant is to prevent the lubricant in the molding of plastic stick on the metal mold, while allowing a smooth plastic surface appearance . Commonly used lubricants are stearic acid , calcium and magnesium salts and the like .
7 antioxidants prevent the plastic molding or WSD Chlorinated paraffin heating at high temperature thermal oxidation during use , leaving yellow plastic , hair crack , etc. In addition to the above additives , the plastic may also be added flame retardants, foaming agents, antistatic agents so as to meet different requirements .

Lubricants can be divided into several
Friction portion for lubrication, cooling and sealing machine
materials.
According to sources of mineral lubricant (such as machine oil),
vegetable lubricant (such as castor oil) and animal lubricant (such as
tallow). In addition, synthetic lubricants, such as silicone oils,
fatty acid amide, oleic acid, polyester, synthetic esters, carboxylic
acid. Depending on the properties of WSD PVC lubricants the lubricating oil, oily liquid,
semi-solid grease-like and solid lubricant grease.
Can be divided according to the use of industrial lubricants
(including oil and grease), the body lubricant.
Many types of lubricants, are widely used. Lubricant is also used to
improve flowability and releasability and other plastic processing, to
prevent adhesion of the mold in the machine and fish eyes or other
defects. Industrial Lubricants
The main function is to reduce the friction surface friction damage.
However, due to a wide range of industrial machinery, machinery mainly

Paraffin put more put less plasticizer is internal / external lubricant
pvc products , the wax is put more plasticizers, put less is internal / external lubricant ?
Paraffin said here refers to the full name of " wax " or " paraffin " ?
I read some of the recipe data , some WSD Titanium dioxide rutile put more than 20 PHR , put some 0.5 PHR.
2 . Put more than 20 PHR definitely soft products plasticizer use , and that this situation will not have a lubricating effect ? Inside or outside lubrication lubrication ?
3 release 0.5 PHR , is not no use as a plasticizer ? Only as a lubricant ? Inside or outside lubrication lubrication ? And this ratio is only hard copies of articles for the formulation , and not for WSD Plastic impact modifier the soft goods formulations are typical chlorinated plasticizer . Copies may want to add to the dozens . All adds a plasticizer has the role of lubrication . But within five hardware products , or the need to add additional components within the slide . Added to 20 parts plus without actually depends on the slip process , as well as product performance, such as the current size of the host processing .
Paraffin is carbon saturated hydrocarbons , petrochemicals inside out , which is used in pvc play a significant WSD Polyethylene wax role outside the slide , add the amount is generally less than 1 .
The role of the gap between the two played in pvc processing is relatively large . See you write so seriously , I suggest you book early aspects of pvc look , or online to understand their role under the type of pvc accessories . Easy to understand for the recipe .

The main performance lubricants commonly used PVC
Common PVC lubricants [2] The main properties are as follows: calcium (1) stearic acid:
White powder, mp 148-155 ℃, non-toxic, have excellent lubricity and workability, no sulfide contamination with lead and basic lead salt soap and use, can increase the rate of gelation, the dosage is generally 0.1-0.4PHR.
(2) polyethylene wax
White or light yellow powder or granules contain small amounts of oxidized polyethylene wax, although polar group is still compatible with the PVC, but the higher the efficiency of the lubrication can be improved lubricity between the polymer and the metal, improving the WSD PVC lubricants extrusion efficiency, improve a colorant dispersion, gives the product a good transparency and gloss. The amount of 0.1-0.5PHR.
(3) stearate
White or light yellow granules, mp 70-71 ℃. Slow evaporation at 90-100 ℃, as external lubricant in PVC processing hardware, the amount is usually 0.2-0.5PHR, and have the effect of preventing scale chromatography, but easy to use excessive blooming.
(4) Glyceryl stearate
Powder substance, melting point 85-87 ℃, has excellent heat resistance and flowability, increase the amount of filler, may contribute to the plasticizing. And waxes and use, to improve the thermal stability of PVC-U. General amount of 0.2-0.6PHR.
In practice it was found that when two or more with the use of the lubricant, when used alone with the emergence of WSD Titanium dioxide rutile a different effect. In profile formulations, the way they use complex
(5) Paraffin
Melting point 57-63 ℃, no polar group, is a typical external lubricant. Because of its low melting point, easy to evaporate, a small melt viscosity, only within a narrow range from lubrication, suitable for single, twin-screw extruder, the general amount of 0.1-0.8PHR. This product is poor transparency, easy to whiten.
(6) Polyethylene wax
White powder, a softening point of about 100-117 ℃, due to its relatively large molecular weight, high melting WSD Stabilizers for pipe point, low volatility and therefore at a higher temperature and shear rate, also showed significant lubricating effect. For hard PVC single, twin-screw extruder, the usual dose is 0.1-0.5PHR.

Pvc composite stabilizer when using the issues that need attention
Now inside the home when the renovation will always be involved in a variety of coatings, paints, latex, etc., and pvc composite stabilizer is also a large number of these kind of decoration materials. As we all know, this material is a polymer compound used in the process, we need to pay attention to a lot of precautions.
First of all, before we open the WSD PVC lubricants packaging of this material, we must ensure that the air circulation around. Because pvc composite stabilizer is highly volatile characteristics, while some of the material composition if not timely flow will cause some damage to the human body in a small space. This is why after the house renovated, within three months do not advise clients to stay, but you want to come out of vacant houses, ventilation diffuser.
Ensure that the air circulation around after we unpack, they also need to know that this material is a liquid or powder form. Is divided into two kinds of liquid and solid existence Pvc composite stabilizer under normal circumstances. If it is a liquid, we use the process on the need to pay attention to a lot of problems, can not let these material gets on our skin, but can not let our mouth ENT inside the eye gets these WSD PVC flame retardant things. When in use must be primarily own security.
The powdery composite stabilizer, we need to keep dry surroundings, pay attention to the fire. In general, a powdery stabilizer liquid stabilizer avoidance safer convenience. But nevertheless, we are both in use which we still need to pay attention to their own protection. As long as we have a reasonable use of these materials, while WSD Azodicarbonamide avoiding disadvantages, we can bring endless benefits for our building homes.
