In decoration and construction projects, it is common to hear various material names, some familiar, while others may have never been heard of or seen before. This is a normal phenomenon. UPVC may also be used to varying degrees during the decoration process. But some people don't know what material UPVC is? Today, the editor brings you some relevant knowledge about UPVC and the characteristics of UPVC materials. I'm glad to share with everyone.
1, What is UPVC material
UPVC is also known as hard PVC. Amorphous thermoplastic resin made by polymerization of vinyl chloride monomer with certain additives. (For example, there are lubricants, fillers, etc.). In addition, the team also scientifically adopted the method of blending modification and combined it with resin. Thus, it constitutes obtaining better practical value in real life. There are PE, MBS, and so on in the resin.
2, Characteristics of UPVC materials
1. UPVC has a high melt viscosity. However, the flowability is relatively weak, and even increasing the injection pressure and melt temperature cannot change the changes in flowability. In addition, to narrow the molding temperature range, the molding temperature of the resin can only be brought closer to the thermal decomposition temperature. UPVC is a material that is difficult to shape.
2. Strong corrosion resistance. Compared with other materials, UPVC has relatively high corrosion resistance, strong resistance to strong acids and alkalis, and will not cause rusting and scaling. Therefore, you can rest assured that there will be no red water when using it.
3. Weak flow resistance. The advantage of PVC pipes is that they have smooth inner walls. The surface roughness coefficient is only 0.009, which reduces fluid resistance and avoids the phenomenon of moisture reduction.
4. The process is non-toxic. UPVC water supply adopts a relatively special green and environmentally friendly lead-free formula system, completely replacing the traditional composite lead salt formula system. So, the phenomenon of damaging water quality will not occur, let alone harm human health.
5. Lightweight, providing good convenience for installation. Under normal circumstances, the density of UPVC is only 5/1 of that of cast iron, providing good convenience for transportation and disassembly. It uses specialized adhesives or elastic seals for sleeve connection, which is more conducive to convenient construction and installation.
6. Good water tightness. After only 15 minutes of adhesive bonding, the bonding strength can reach no less than 12.5/c. The service life is very long, and there will be no significant decline during use. There is no worry about aging or water leakage.
UPVC can be commonly seen in many regions or building materials markets. Although UPVC plays a relatively important role in home decoration, it is still necessary to understand what material UPVC is. Today, I will share with you here, hoping to help you further understand UPVC materials.
