20180829 automatic PP PE ABS PMMA PC PS plastic sheet production line

Twin screw extruder 

Product Characteristics:
1, Modular principle design for screw configuration and barrel setup makes combination and cleaning convenient , also easy to adapt to customers' requirements .
2, Different kinds of pelletizing modes can meet specific material properties: water-cooling strand pelletizing, air-cooling hot-cut pelletizing, water-ring pelletizing, under water pelletizing, etc.
3, Screw elements and kneading blocks are made of high tool steel , with high corrosion-resistant and high wear-resistant.
4, Barrels are made of high quality nitrided steel , corrosion proof and antifriction.
5, Vacuum system fulfills devolatilization to ensure the quality of polymer processing

Calcium carbonate was used to plastic industry a large number of  is not accidental, compared to other non-metallic mineral powder material, calcium carbonate has obvious advantages. 1) Inexpensive Both TSP and light calcium are the cheapest in a variety of non-mineral powder materials, meaning that any non-mineral powder material will only attempt to replace calcium carbonate as a plastic filler rather than highlighting this The characteristics of the powder material itself, it is meaningless.

2)color is good ,is easy to put color,could make color light plastic product. Inadvantage is the plastic product color is not enough bright.in most cases is acceptable.

3)low hardness,much less than the manufacturing processing machinery equipment and molding the wear is light to the contact parts (screw,barrel etc) and molding.

4)Good thermal stability and chemical stability

5)Is easy to dry ,without crystallographic water, and the moisture of adsorption is easily removed by heating.

6)avirulent, without excitant, tasteless, especially our country is rich in calcite, marble, limestone resources,  choose room is big, the vast majority of resources are of good quality, especially the heavy metal content is extremely low, to fulfill the requirements of national health level.
