Introduction of plastic lubricants

 Plastic lubricants typically melt after the polymer has a higher viscosity, in the process, the molten polymer through the slit in the gate channel, etc., bound to a polymer melt processing machine with the friction surface some of the processing of the polymer in the friction is very unfavorable, so that the friction is reduced melt flow, and cause severe friction film surface becomes rough, or the lack of luster appears rhyolite. To do this, need to be added in order to improve lubricity, reduce friction and adhesion properties for the purpose of lowering the interfacial agents. This is the plastic lubricants. Plastic lubricants in addition to Plastic lubricants the fluidity, the accelerator may be from a melt, anti-adhesion and anti-static agents, slip agents and the like effect. Plastic lubricants can be divided into two kinds of external lubricant lubricants and internal and external lubricant role is mainly to improve the friction polymer melt processing equipment with hot metal surfaces. Plastic lubricants poor compatibility with the polymer is easy to migrate out from the melt, so the lubrication can be formed in the plastic sheet with the metal melt interface. Internal lubricants have good compatibility with the polymer properties, which serve to reduce the PVC lubricant  of cohesion between the polymer molecules within the polymer, thereby improving the internal friction of the plastic melt of the heat and melt flowability. Commonly used lubricants are stearic acid and its salts outside; internal lubricant is a low molecular weight polymer. Some lubricants have other functions. Each lubricant has actually can achieve a required role, internal and external lubrication always together, but in a way more prominent. A lubricant with different polymers under different processing conditions or exhibit different lubrication, such as high temperature, high pressure, the lubricant will be squeezed out of the inside and outside of the lubricant becomes.

Plastic lubricant definition and classification

Plastic lubricant defined: the polymer after the melt generally have a higher viscosity, in the process, the molten polymer through the slit in the gate channel, etc., bound to a polymer melt processing machine with surface friction, the friction of the processing, some of the polymer is very unfavorable, so that the friction is reduced melt flow, and the friction causes a serious film surface becomes rough, or the lack of luster appears rhyolite. To do this, need to be added in order to improve Plastic lubricants , reduce friction and adhesion properties for the purpose of lowering the interfacial agents. This is the lubricant. In addition to improving the mobility of the lubricant, but also can play a melt accelerator, anti-adhesion and anti-static agents, slip agents and the like effect. Plastic lubricant Category: Lubricants can be divided into two kinds of external lubricant PVC lubricant  and internal and external lubricant role is mainly to improve the friction polymer melt processing equipment with hot metal surfaces. It is less compatible with the polymer is easy to migrate out from the melt, so the lubrication can be formed in the plastic sheet with the metal melt interface. Internal Plastic lubricants have good compatibility with the polymer properties, which serve to reduce the effect of cohesion between the polymer molecules within the polymer, thereby improving the internal friction of the plastic melt of the heat and melt flowability. Commonly used lubricants are stearic acid and its salts outside; internal lubricant is a low molecular weight polymer. Some lubricants have other functions. Each lubricant has actually can achieve a required role, internal and external lubrication always together, but in a way more prominent. A lubricant with different polymers under different processing conditions or exhibit different lubrication, such as high temperature, high pressure, the lubricant will be squeezed out of the inside and outside of the lubricant becomes.

Plastic lubricants Introduction and Application

The selection of lubricants, generally considered to be the movement of the friction material, surface roughness, the working environment and working conditions, as well as lubricant performance and other factors. Mechanical devices, mostly through the lubricant to each lubrication distribution system requiring lubrication. Friction portion for Plastic lubricants , cooling and sealing the mechanical material. Many kinds of lubricants, are widely used. Lubricant is also used to improve the flowability and releasability of the plastics and other PVC lubricant , to prevent adhesion in the mold in the machine to produce fish eyes or other defects. The main function is to reduce the friction surface of the friction damage. However, due to a wide range of industrial machinery, machinery mainly to meet the requirements of lubricants to reduce friction, wear, there are some special requirements vary depending on the work environment, working conditions and proposed. Used medical equipment and more equipment for the iron plated with nickel chrome layer. When the nickel-chromium layer is damaged, impure iron (carbon) is exposed to air, the oxidation reaction occurs upon contact with oxygen and water, the occurrence of corrosion. Use of medical surgical instrument lubricant, can effectively prevent or delay the corrosion of surgical instruments.Plastic lubricants to reduce friction pair friction, slowing the wear of lubricating medium. Lubricants can play on friction cooling, cleaning and prevent pollution and so on. In order to improve the lubrication performance of the lubricant may be added in some suitable additives.

WSD intenal lubricant Classification and mechanism of action of the lubricant

  In the plastics industry mainly used as PVC lubricants mold release agents, plasticizers, antistatic agents, especially for plastic foam products, anti-shrinkage agents. In the production of  PVC lubricant  as an internal lubricant, and can be used as an alkyd resin modifier, a plasticizer of cellulose nitrate. Lubricants [1] The resin is effective for improving the fluidity and plastic processing products releasability to prevent adhesion of the machine or mold, and internal defects.  
  General increase in the mold cavity plastic or coated surfaces. Common lubricants are fatty acids and their salts, long chain aliphatic hydrocarbons. Depending on the Plastic lubricants of action of the lubricant can be divided into external lubricants and internal lubricants. (1) external lubricants: the lubricant with a poor compatibility with the molding resin, so commonly used in the molding machine or the mold, forming a lubricating layer between it and the resin, the resin flow and easy demolding , such as paraffin. (2) Lubricants: Lubricants such good compatibility with a resin, often incorporated into the resin, the lower the melt viscosity of the resin, to improve its flowability. Such as butyl stearate, lead stearate. Stearic acid salts are both good lubricant, but also to be effective stabilizers.
