PVC free foam board is widely used in modern industry, its main component is composed of polyvinyl chloride, which has a good effect in heat resistance, toughness, and extensibility. Although the main component of PVC is polyvinyl chloride, other components are also added, taking them as the upper layer, which is composed of paint. It is very popular with modern enterprises and is widely used in all aspects of the market. Today, I will introduce the construction technology of PVC free foam board.
1, pipe processing: After the length of the pipe is determined, the hacksaw can be manually cut or circular saw blade, sawing machine cutting. The cuts at both ends should be kept flat. Use a butterfly file to remove raw edges and chamfer. The chamfer should not be too large.
2. Bonding of pipe fittings: test assembly before bonding, clean the outer surface of the inserted pipe end of about 50mm and the inner wall of the pipe fitting, and then scrub with cotton yarn coated with acetone, and then evenly coat the adhesive surface of the two with a brush, without leakage. After the coating is finished, rotate to the ideal combination Angle, insert the pipe into the socket of the pipe fitting, knock with a mallet, so that the pipe is all inserted into the socket, can not be opened or changed in two minutes, and wipe the adhesive extruded at the joint in time to keep the pipe clean.
Each layer of the riser is equipped with a expansion joint to compensate for the thermal expansion and contraction of the countercurrent pipe.
Three-way installation should pay attention to the direction of the water, to facilitate the installation of the horizontal pipe when the natural slope c. The height of each riser is within 3m, consider setting a pipe hoop. The horizontal pipe is fitted with a hanger every 0.6m.
When the linear distance between the horizontal pipe and the drain pipe is greater than that specified in Table 4, an inspection or cleaning port should be set up
The above is the main content of the construction process of PVC free foam board, I hope to help you.
