PVC plastic molding character

PVC plastic molding character
PVC plastic board the full name is Polyvinylchlorid, ingredient for polyvinyl chloride, bright color, resistant to corrupt and durable, due to the increase in manufacturing process of plasticizer, anti-aging agents some toxic auxiliary material to strengthen
The heat resistance and toughness, and extendibility, so their products generally does not store put food and medicine.
PVC plastic molding character:
1. The amorphous materials, moisture absorption small, poor liquidity. In order to improve the liquidity, prevent the occurrence of bubble son, plastic can dry in advance. Mould casting system should be thick short, clear the dust removal of dust fittings bag fittings note, gate section should be big, do not have a corner. Mould should be cooling, chromium plating surface.
2. Because of its corrupt sex and liquidity characteristics, had better use of special equipment and mold. All products must according to need to join different kinds and number of additives.
3. Extremely easy differentiation, in 200 degrees temperature and steel. Copper contact more differentiation, differentiation to escape corruption. Excitant gas. Molding temperature range.
4. The screw injection machine nozzle childhood, aperture is big, in case the blind Angle stagnation expected. Not with set piece, such as a set piece should be preheated.
It is when the contemporary world are loved, general vogue and also be widely used a synthetic materials. It seems the global in various $become useful to guess at the second. According to statistics, only 1995 a year, in the life of the European PVD
Production is about WuYiBaiWanDun, pressure tile machine, and the consumption is five million three hundred thousand tons. In Germany, the production and consumption PVD equal to one million four hundred thousand tons. PVD are with 4% of the increase in global rate have to production
And the application. In recent years the PVD increasing number of degrees in southeast Asia is especially significant, thanks to southeast Asia the capital have held the construction of infrastructure demand note, pipe fittings "copper alloy seamless tube" judge international progress for fathers brought forth level. Can production in 3 d surface film of material guess, PVD is the most suitable
Materials. Proportion: 1.38 g/cubic centimeters, molding tightening rate: 0.6-1.5%, molding temperature: 160-190 ℃.
Features: mechanical performance, excellent electrical performance, fitting leading enterprise mobilization elbow pipe fittings industry spanning development, acid and alkali resistant force is extremely strong, chemical stability, but softening point low. Suitable for making thin plate, electric wire and cable insulating layer, seals, etc.
