release agent is a kind of functional material between mould and finished products, is to prevent the rubber, plastic, the mold of elastomers or other materials, laminated products such as bonded to the mold, or other board face, easily from the role of processing AIDS. Due to injection molding, extrusion, calendering, moulded, laminating technology rapid development, such as release agent dosage is also greatly improved.
release agent sort is more, the correct reasonable use of release agent is very important, in be used actually, being asked to release agent with excellent mold, mold release, shorter operation time, easy to clean, a trace on the surface of a finished product, economically affordable, to health, fire prevention and safety when using, viscosity changes with the seasons, not for tooling and equipment shall be no corrosion and pollution, at the time of molding color, no smell, not sticky, etc.
release agent in the role of plastic injection molding can produce two kind of friction, heating is a kind of polymer melt polymer molecules between the internal friction, the other is a polymer melt and processing of mould surface friction. Function is easy to make the melt flow rate is reduced because of friction, produce adverse results, performance is: the poor processing performance and processing speed is slow, product is not easy to full of complicated shape mould, injection molding products processing surface is rough, lack luster, serious formation of wrinkles and other problems. To overcome the above two kinds of friction is one of the effective ways is to add lubricant.
high-grade products and need a second processing ( Such as painting and printing) Want to choose the release agent is suitable for secondary processing. To prevent pollution of the environment, should choose won't burn, smell and less toxic mold release agent. In the release agent chooses, economy is an important factor cannot be ignored.
tuomoji divided into two categories, external and internal lubricity lubricity.
the former mainly improve the lubricity of polymer molecule itself, it requires with polymer resin with a certain degree of affinity or intermiscibility. The latter is to improve the mold between polymer and lubricity. Therefore it is important for its choice of release agent general requirements are as follows: easy to use, short drying time; Operation safety, non-toxic; Smooth, good film forming; To mould non-corrosive, there is no change on the resin curing; The adhesion strength of the resin is low; Make easy and cheap.
classified by usage: release agent, release agent;
2。 According to the classification of life: conventional demoulding agent, semi-permanent release agent;
3。 According to the shape classification: solvent release agent, water-based release agent, solvent release agent, powder release agent, paste release agent.
