One、 PPR pipes are heat-fused or glued?
PPR pipes are typically connected using a heat fusion method, as this provides a more secure and reliable connection, reducing the risk of breakage. However, gluing is also possible. However, the adhesives used for gluing PPR pipes are chemical substances with inherent toxicity. Therefore, after application, adequate ventilation is required before the product can be used.
Two. PPR pipe hot melt method
1. First, plug in the hot-melt adhesive gun. The hot-melt adhesive gun has two indicator lights: red and green. The red light indicates that the gun is ready for use.
2. Using PPR-specific scissors, cut the PPR pipes to the required dimensions. When cutting PPR pipes, the cut ends must be perpendicular to the pipe axis.
3、 Immediately wipe away any stains on the PPR pipe with a cloth, ensuring that the pipe is completely dry.
4、Without rotation, insert the pipe end into the heating mold head, ensuring it is inserted to the specified depth, and simultaneously, push the pipe fitting into the heating mold head to reach the designated mark.
5、After the heating time is reached, immediately remove the PPR pipe and fittings from the heating mold. Quickly and uniformly insert them into the heated area without rotation, ensuring that a uniform bead is formed at the joint. Also, control the rebound after insertion.
III. PPR Pipe Bonding Method
1、Before bonding PPR pipe and fittings, use a clean cloth to wipe the inner and outer sides of the socket and the outer side of the insertion opening. If the surface is contaminated with oil, it must be cleaned with acetone.
2. When applying the adhesive, first apply it to the inner side of the recess, then apply it to the outer side of the recess. When applying to the recess, apply an appropriate amount evenly along the axis, from inside to outside, without any gaps or over-application.
3、After applying the adhesive, maintain the applied pressure for at least 1 minute to ensure the joint remains stable and properly aligned.
4、After bonding, promptly wipe away any excess adhesive, and avoid applying any pressure or load during the curing time.
