1. Amorphous material, low moisture absorption, poor fluidity. In order to improve fluidity and prevent bubbles, the plastic can be dried in advance. The mold casting system should be short and thick, the gate section should be large, and there should be no dead corners. The mold must be cooled and the surface is chrome-plated.
2. Due to its corrosive and fluid characteristics, it is best to use special equipment and molds. All products must be added with different types and quantities of additives according to needs.
3. It is easy to decompose, and it is easier to decompose when it comes into contact with steel and copper at a temperature of 200 degrees, and it will escape corrosive and irritating gas during decomposition. The molding temperature range is small.
4. When using screw injection machine nozzles, the aperture should be large to prevent dead ends from stagnating. It is better not to have inserts. If there are inserts, they should be preheated. Soft PVC Gifts PVC (Polyvinyl Chloride) is a flame-retardant, chemically stable material that only produces low tensile stress. At the same time, its material characteristics also include high strength, high rigidity and high hardness. The working temperature ranges from minus 15 degrees to 60 degrees. It can be bonded and welded. Environmental protection PVC PVC main characteristics: strong corrosion resistance: most suitable for anti-corrosion equipment in the chemical industry. Easy processing: cutting, welding, and bending are all extremely simple. High strength, high rigidity and high hardness; good electrical insulation; good chemical stability; self-extinguishing; low water absorption; easy to bond and easy to paint. The price is low.
PVC application fields: acid inspection manufacturing tower, seawater concentration tank, photo washing equipment, electroplating tank, battery box, electric meter board, audio base cover, radio bottom plate, various electrical insulation boards, cement tank lining, machine windshield , Exhaust air duct engineering, stationery, building materials, etc.
