For drinking water, PE is generally used as cold water pipe; PP-R (special hot water material) can be used as hot water pipe; PP-R (cold water material) can also be used as cold water pipe; If to be used as hot water pipe, of course PP -R is good; (If it is a drinking water pipe in a home decoration, then there is no need to distinguish, basically PP-R is used more than PE) If it is a cold water p
PVC wood plastic extrusion production process 1. Process parameters 1.1 General information Extrusion molding process generally includes molding temperature, screw speed and metering feeding speed, traction speed, extruder working pressure, exhaust and vacuum cooling and many other aspects. However, the extrusion process is also related to the formula system, extruder structure performance
The wood-plastic is a new kind of synthetic material which uses PVC,PP,PE resin or recycled plastic and plant fiber ( wood powder, chaff, straw etc.) as raw material and through the process of mixing, granulation, extrusion, calibrating, drawing off and cutting. This kind of wood-plastic materials are not only very similar with natural wood in appearance and feel, but also with the same ch

Introduction and feasibility report of SPC floor production line for stone plastic floor 1. Description of stone plastic floor, SPC (SCB), MCB floor: Stone plastic floor (SPC floor) is a product made by extruding the PVC base material by an extruder, using a four-roll calendering unit to separately laminate the PVC color film + PVC wear-resistant layer + PVC base film at one time. The proces
There are too many plastic pipes on the market, such as PPR pipes, PE pipes, PVC Pipes etc. How do you distinguish between hot water pipes and cold-water pipes? What are their applications? Let me introduce several types of pipes that are often encountered in daily life. 1. Hard polyvinyl chloride (PVC-U) pipe for water supply The PVC-U pipe’s main raw material is sanitary grade polyviny
1. Raw materials: The difference between the exterior wall hanging board and the interior wall decoration board is that it needs functions such as radiation resistance, high temperature resistance, ultraviolet ray resistance, and aging, which has higher requirements for materials. PVC exterior wall hanging board can be understood in this way. It is divided into two layers. The top is the co-extrud
