Because there is no central axis interference and the effect of the inner lining plate, it has special advantages for conveying belt-shaped, viscous materials, and easily entangled materials. For example, it is used for conveying medium and fine gratings in sewage treatment plants. Machine grid slag and filter press mud cake and other materials, or garbage disposal sites to handle transportation garbage, can prevent accidents caused by blockage.
Specifications: according to the diameter of the spiral, or the user can directly provide the diameter, circumference, thickness, etc. of the lining plate.
Diameter range: diameter 200, 220, 240, 260, 280, 300, 320, 340, 360-660mm
Circumference: 400, 425, 460, 490, 520, 560, 590, 620, 640, 680, 710, 740, 770, 800, 840, 870-1050mm
Thickness: 8, 10, 12, 15mm
The performance advantages of screw conveyor lined with UPE polymer lining board:
1. High wear resistance: the coefficient of static friction is 0.07;
2. Corrosion resistance: It can be used in concentrated hydrochloric acid at 80 °C, and has stable performance in 75% concentrated sulfuric acid and 20% nitric acid.
3. Impact resistance: The impact resistance ranks first in nylon, and it is difficult to crack it whether it is strong external impact or internal pressure fluctuation. Its impact strength is 20 times that of polyvinyl chloride, 10 times that of nylon 66, and 8 times that of polytetrafluoroethylene.
4. Low temperature resistance: It has a certain ductility at a low temperature of -269 ℃.
5. Electrical properties: large volume resistance, breakdown voltage of 50KV/mm, and dielectric constant of 2.3.
6. Hygienic and non-toxic: tasteless, non-toxic, odorless and non-corrosive.
