How to reduce the viscosity (viscosity) of the melting polymer?

Proper temperature, add lubricant

If this topic is discussed in Chinese to discuss stickiness, it will be very confusing. In fact, LZ may want to reduce Cohesive instead of Viscosity, or simply encounter the problem of melt transportation difficulties. This is another topic.CoheSive is more related to the nature of the interface, such as the polarity of the melt, the surface treatment and smoothness of the screw, and it should also have a certain relationship with Viscosity, because the extremely low Viscosity will allow the molecular chain of the melt to spread to the screwIn the depression on the surface, the friction of the melt and screw is increased. When the friction force of the melt and screw is greater than the friction with the cannon wall, it will be manifested as the melt around the screw and does not transfer forward.Therefore, the solution or changes the formula of the melt polarity, or repair the screw surface to ensure the highlights of the screw. If possible, make the screw cooling, and finally consider the melt VISCOSITY of the feding section.

There are all high -molecular processing books. Increased temperature must be a method, increasing the shear rate

The best way is to change the material. Of course, increase the temperature can reduce viscosity, but to a large extent, it will cause the molecular chain to break, which is unfavorable to the components after forming.
