1. This resin includes CPVC, PE, ABS, EVA, MBS, etc. UPVC has high melt viscosity and poor flowability. Even if the injection working pressure and melt temperature are increased, the change in flowability is not large. In addition, the molding temperature of the resin is very close to the thermal decomposition temperature, and the temperature range that can be molded is narrow, which is a kind of raw material that is difficult to mold.
2. U-PVC winding winding pipe, also known as double flat-wall steel-plastic composite winding pipe, is a new type of new technology today. Compared with him, there are cement pipes. All in all, it has advantages.
What are the specifications and models of pvc pipes
PVC pipes can be divided into soft PVC pipes and hard PVC pipes according to different characteristics. The key difference is whether they contain plasticizers. The soft PVC pipe has a small company, so the physical properties are relatively weak, and it cannot bear a certain pressure. Therefore, soft PVC pipes are usually used on the surface of suspended ceilings, floor tiles, and leather products, and are often used as line pipes.
1. There is no plasticizer in the rigid PVC pipe. It is very easy to form during production and has good physical properties. Rigid PVC pipes are usually used as drainage pipes and water supply pipes, and have great comprehensive utilization value.
2. The market share of soft PVC pipes in the market is only one-third, while the hard PVC pipes account for two-thirds. The raw materials of PVC pipes are not completely thin, but environmental protection additives can be used to make them non-toxic and odorless green products.
3. The specifications of PVC pipes should be distinguished according to their types. The nominal outer diameter specifications of different types of PVC pipes are different. The nominal diameter of flexible PVC pipe is up to 50mm, and it is usually not easy to exceed this specification. The nominal diameter of the rigid PVC pipe can be quite large, even 50cm in size.
4. The specifications of soft PVC pipes are implemented in accordance with GB/T13527.1-1992, and the specifications of hard PVC pipes are implemented in accordance with GB/T13020-1991. Common ones are 2.5mm, 3mm, 4mm, 5mm, 6mm, etc.
If you want to buy water pipes, it is recommended to go to the local reliable home building materials market to buy, pay attention to choose the products of reliable manufacturers, so the quality is more guaranteed, the above is about pvc-u pipe and pvc pipe What are the differences and what are the specifications and models of pvc pipes? Everyone should pay attention to the way of purchasing and pay attention to quality when purchasing water pipes.
