some of the main principles of the processing aid for processing

1, the role of the principle of PVC processing aids melt due to poor scalability, easily lead to melt broken; PVC melt relaxation slow, easily lead to the product surface rough, dull and shark skin and so on. Therefore, processing often requires the addition of PVC processing aids to improve the melt processing aids described above is the lack of processing performance can be improved resin additives, and its main role in three ways: to promote the molten resin to improve the rheological properties of the melt lubrication and promote the molten resin to give: PVC resin in the WSD PVC flame retardant  heated state, when the shear force under certain melt processing modifier first melted and adhered to the surface of the PVC resin particles, its compatibility with the resin and Its molecular weight, the viscosity of PVC and increasing the friction, and thus the shear stress and the effective heat transfer to the PVC resin, melt rheology improving the acceleration performance of the molten PVC: PVC has a melt strength is poor, poor ductility, and melt fracture shortcomings, and to improve the melt processing of said modifier rheology. Its mechanism of action: Increase the PVC melt viscoelasticity, thus improving the die swell and melt strength gives improved lubricity: PVC processing modifier is compatible with the first portion of the melt, plays the role of promoting the melt; but not with PVC Compatible part WSD Polyethylene wax  migrate to the outside of the molten resin system, thereby improving the releasability of the copolymer 2, a conventional processing modifier ACR ACR methyl methacrylate and acrylate, and styrene monomers. In addition to be used as a processing aid, it can also be used as impact modifiers. PVC plastic window profiles or generally used ACR201 ACR401, in an amount of 1.5-3 parts of a modified impact modifier polymer content is important to improve the impact resistance, PVC resin is a non-polar high crystallinity there is a strong interaction between the oligomer molecule, is a hard and brittle material; low impact strength. After the addition of impact modifiers, elastomeric impact modifier particles can be raised to reduce the total stress crazing and  WSD zinc stearate its particle deformation and shear band and prevent crazing expansion and growth, absorb the impact of the transmission of the body material able to achieve the purpose of impact. Small particle modifier to facilitate increasing the number of unit weight or unit volume of a modifier to increase the effective volume fraction, thereby enhancing the ability of stress dispersion. Currently used widely for organic impact modifier.

There are many kinds of plastic processing aid methods

About plastic extrusion, injection molding, blow molding, rotational molding, casting, dip and other plastic molding process, depending on the specific choice of materials and products, the advantages and disadvantages of hard to say.
  Here I am with PE plastic processing methods simply lower, PE available a wide manufacturing different processing method. As the main raw material ethylene, propylene, 1 - butene, hexene copolymer, under the action of a catalyst, using a slurry polymerization or gas phase polymerization process, the polymer obtained by flash separation, drying, granulation, etc. processes, was
Uniform particles have finished. Including such sheet extrusion, film extrusion, pipe or profile extrusion, blow WSD Plastic impact modifier  molding, injection molding and rotational molding. Extrusion: grade for extrusion production generally has a melt index of less than 1 and the width to wide MWD. In the process, the availability of suitable MI low melt strength. Broader MWD is more suitable for extrusion grades, because they have a higher production speed, lower the die pressure and melt fracture reduction trend. There are many PE extrusion applications, such as wires, cables, hoses, tubes and profiles. Pipes for natural gas applications ranging from a small section of yellow tube to 48in diameter thick-walled clarinet for industrial and municipal pipes. Alternative to large diameter hollow wall  WSD zinc stearate made of concrete pipe used as rainwater drains and other sewer pipelines rapidly.
Sheet and thermoforming: Many large picnic-type freezer thermoforming lining is made of PE, with toughness, light weight and durability. Other sheet and thermoformed products include fenders, tank linings, disc bowl guard, transport boxes and cans. The rapid growth of a mass-sheet applications are mulch or bottom in the village, which is based MDPE with toughness, chemical resistance and impermeability. Blow: These range from equipment bleach, oil, detergent, milk and a bottle of distilled water into WSD PVC stabilizer  a large refrigerator, car fuel tank and the canister. Blow molding grade characteristic indicators, such as melt strength, ES-CR and toughness, and the sheet for thermoforming applications level
Similar, it can be used with similar grade.

Use the principle of PVC processing aid

In industrial production, in order to improve production processes, improve product quality and yield, or to give the product of a specific application performance by adding auxiliary chemicals. Also known as the additive. However, as an important component of the product matrix, the product shape, structure, performance of large doses have a significant impact of additional material, generally not included in the scope of aid. Additives wide range of applications, usually re-dubbed the role of one pack stabilizer  object names, such as polymeric additives, water treatment, metal surface treatment agent. There are some common additive selection considerations, such as: ① use of the additive requirements. Additives appearance, odor, contamination resistance, durability, electrical properties, weather resistance and so the use of direct impact products. ② processing conditions additives adaptability. ③ durability additive. Loss additive mainly through evaporation, extraction and migration pathway 3, the species must be selected appropriately according to the environment and the article processing conditions. ④ compatibility with polymer additives. Comprises mixing in impact resistance and stability of each may be a problem between them. ⑤ additive toxicity. Food and drug packaging materials, water pipe, medical equipment and other polymer materials, products, their health mainly depends on additives used. ⑥ synergistic and additive effect between proposition. If chosen appropriately, the mutually reinforcing, and can reduce the total amount of additives. The use of additives principles:
The current provisions of the international system can be divided into two, one is to allow the use of additives "exhaustive" "whitelist" lists, and the other is listed aids disabled "disabled list." After years of practice, "disabled list" to be found there is a big drawback: the lack of new substances binding. Plastic profiles Promoters
Additives a plastic profiles: impact modifiers, such as the production of plastic profiles without impact modifier, plastic profiles will be very brittle, a little collision, easily broken. Commonly  chromium oxide Titanium dioxide rutile used in the production of plastic profiles impact modifier modifier consists of the following three categories: chlorinated polyethylene, polyacrylate, ethylene - vinyl acetate copolymer. Plastics Additives two sections: heat stabilizers plastic profiles are heat-sensitive plastic, so plastic profile production machining, heat stabilizers is essential. Metal heat stabilizers in PVC can absorb decomposition of HCL, it can slow down the rate of decomposition of plastics and extended decomposition time, the production of plastic profiles for the most commonly used compound lead salt, high-efficiency thermal stability, low prices. Plastics Additives three  sections: the main processing aid processing aids plastic molding  PVC lubricants process in order to improve the performance improvements and the development of a class of additives. Plastic profile processing temperature and decomposition temperature relatively close, poor mobility, easy to stick on the device coking, and therefore the production of plastic profiles need a certain amount of processing aid to overcome the defects of plastic profiles itself.

Types of additives and introduction

Sweeteners - commonly used artificial sweetener saccharin sodium,

sodium cyclamate. The purpose is to increase the sweetness sensation.
Preservatives - are commonly used sodium benzoate, potassium sorbate,

sulfur dioxide and lactic acid. For jams, preserves and other food

processing.
Spice - synthetic fragrances, but  WSD Metallic stearate also natural, flavor a lot. Consumers

eat chocolate all tastes, widely used in the production process of

various spices, it has a variety of unique flavors.
Coloring agents - commonly used synthetic pigment has carmine,

amaranth, lemon yellow, indigo and so on. It can change the appearance

of the food, it increased appetite.
Thickeners and stabilizers - can improve or stabilize the physical

properties of cold food, make food look smooth and delicate. They make

ice cream and other frozen food long-term organizational structure

soft, loose.
Nutritional supplements - can enhance and supplement certain

nutritional content of food. Such additives are a variety of vitamins,

amino acids, inorganic salts, etc., can make food food nutrition

fortifier meet different consumer needs. Such as various infant formula

to contain a variety of nutrition  WSD Plastic impact modifier enhancer, so milk to ensure the needs

of children of different ages on a variety of nutrition.
Antioxidants - can extend shelf life of food. Commonly used dimensions

C, C, etc. A different dimension.
Leavening agent - part of the candy and chocolate add leavening agent,

can contribute to ribosomes produce carbon dioxide, which play the role

of leavening. Leavening agents are WSD Aluminum hydroxide  commonly used sodium bicarbonate,

ammonium bicarbonate, composite leavening agent.
Sour agent - part drinks, candy and other sour agent often used to

regulate and improve the flavor effect. Common citric acid, tartaric

acid, malic acid, lactic acid and the like.
Brightener - benzoyl peroxide is the main ingredient of flour

brightener. China's food allowed in the flour to add maximum dose of

0.06g/kg. Brighteners exceeded, will destroy the nutritional flour

produced after acid hydrolysis may cause liver damage, benzoyl peroxide

in the EU and other developed countries has been banned as a food

additive. Green food production, processing, A grade, AA grade products

depending on the product itself or production needs, food additives can

be used in AA grade green food only allows the use of natural food

additives are not allowed to use synthetic chemical food additives, in

A grade green synthetic chemical can be used in food additives, in

green food production, in accordance with national standards and

reasonable use of additives, it is because, in addition to raw, fresh,

and can achieve commercial sterility of conditions of production,

storage, unpackaged food, processed foods have direct or indirect, more

or less use of food additives, the raw salt Take for example, our legal

elements in salt iodization, and adding iodine supplements, food

additives is in a class. So green food production enterprises,

especially the production and processing products.
Food additives to improve food quality and color, smell, taste, shape,

nutritional value, as well as the preservation and processing of food

needed to join in chemical synthesis or natural substances, green food

processing products, in production should be higher level, the rational

use of additives, developed a variety of varieties of products and

constant innovation to meet consumer needs, according to the current

food processing enterprise view of the problems reflected in the use of

food additives on the main The following two questions:
First, because the safety of food additives, misunderstanding, people

tend to think that natural than synthetic chemical food additive

safety, the actual toxicity of many natural products due to the current

detection methods, content detection limit, still can not make accurate

judgment, and, comparing the detected results had natural food additive

is not smaller than synthetic toxicity.

The main difference between the two points of stearic acid and calcium stearate

Stearic acid are calcium stearate are salts. Salt meanings:
Refers to a salt of a metal ion or an ammonium ion (+ NH4) ion or a compound with a combination of non-metallic ions . Such as sodium chloride , calcium nitrate , ferrous sulfate, ammonium acetate and the like , such as calcium sulfate , copper chloride , sodium acetate , the salt is generally in the metathesis reaction product , such as sodium sulfate and sodium hydroxide , and water is generated , there are also other salts can be generated in the reaction , e.g., a substitution reaction . Solution of a soluble salt of a conductive , because the solution to be freely mobile ions , therefore can be used as an electrolyte. It would appear that calcium stearate containing metal ions on the calcium salt , literally you can see . Acid meaning:
The acid in solution chemistry is the ionization of hydrogen ions and cations can completely compound of purple red litmus test solution . In a narrow sense can be divided into inorganic acids, organic acids . Acid proton theory: acid is a substance capable of releasing a proton referred acids. Stearic acid is an organic acid , a certain acidity. Loss of hydrogen ions combine with calcium metal thing is calcium stearate . 1 , the appearance of nature
Stearic acid is a white or creamy -white powder or crystalline lumps, which has a cross-section of microstrip shiny fine needle crystals; similar grease micro odorless, tasteless. Calcium stearate is a white powder , insoluble in water , cold ethanol and ether, dissolved in hot benzene, turpentine , and other organic solvents. Slightly soluble in hot ethanol and ether. When heated to 400 ℃ slowly decomposed , flammable , met decomposition of stearic acid and corresponding calcium , hygroscopic . 2, use comparison: stearic acid cream and cream for skin care products from these two types of emulsion , so that it becomes a stable white paste. Stearic acid or manufacturing honey and almond milk the main raw material . Stearic acid esters in cosmetics, soap industry is more widely used. Calcium stearate heat stabilizers for PVC and other plastic processing lubricants , mold release agents and the like. In rigid products , and the base of lead salts , lead soap can increase the rate of gelation . Also used in food packaging, medical equipment and other requirements of non-toxic soft film and equipment. Can be made of polyethylene , polypropylene, halogen absorbers to eliminate the adverse effects of residual catalyst on the color and stability. As plasticizers in rubber processing , enabling natural rubber and synthetic rubber to soften the whole , and almost no effect on curing . Also used as polyolefin fibers and molded plastic lubricants , grease thickening agent, textile waterproofing agent, paint flatting agent , plasticizer manufacturing plastic labels and so on. Also used in pencil manufacturing and medicine, perfume industry .
