Filling property of PVC water supply pipe

Filling property of PVC water supply pipe
Because of the PVC resin flow is poor, melt viscosity and thermal stability performance is low, resulting in poor performance of PVC resin molding, easy decomposition, etc., these properties will makes PVC pipe fittings and other products easy to become brittle, cracking, hard, poor toughness, aging fast, not cold and, therefore, need to modification of PVC resin, to make up for the shortcomings of the PVC resin. Filling modification is one of the methods of modified PVC resin. Is mainly by adding organic or inorganic fillers to improve the performance of certain aspects of the.
First, the addition of metal powder, such as copper, aluminum is used to improve the electrical properties of PVC resin;
Two, adding red mud, improve PVC products light aging resistance, heat resistance and so on, at the same time, but also reduce the cost of raw materials;
Three, adding iron oxide magnetic powder, improve the magnetic properties of PVC products;
Four, adding wood powder, mainly to reduce the proportion of PVC products to make it more close to the wood;
Five, adding calcium carbonate, used to improve the hardness of PVC products.
By filling the change of different PVC resin modified method can according to the different needs of different PVC products to obtain their required properties of PVC resin, so as to obtain the various properties of the PVC pipe fittings products.
