Forming Characteristics Of PVC Plastic Hose

1. Amorphous material, low moisture absorption and poor fluidity In order to improve fluidity and prevent bubbles, plastics can be dried in advance The mold pouring system should be thick and short, the gate section should be large, and there should be no dead corner The mold must be cooled and chrome plated on the surface;

2. Due to its corrosive and fluidity characteristics, it is best to use special equipment and molds. All products must be added with different types and quantities of additives as required;

3. Very easy to decompose, with steel at 200 degrees Copper contact is easier to decompose, and corrosion escapes during decomposition Irritant gas Small molding temperature range;

4. When the screw injection machine nozzle is used, the aperture should be large to prevent dead corner and material stagnation It is better not to bring inserts. If there are inserts, they should be preheated.

Due to its high chemical stability, it can be used to make anti-corrosion pipelines, pipe fittings, oil pipelines, centrifugal pumps and blowers. PVC hard board is widely used in the chemical industry to make the lining of various storage tanks, corrugated boards of buildings, door and window structures, wall decorations and other building materials. Due to its excellent electrical insulation performance, it can be used to manufacture plugs, sockets, switches and cables in electrical and electronic industries.
