Super wear-resistant composite pipe with steel mesh framework What are the bonding methods of the adhesive?
1. Before the pipes and pipe fittings are bonded, the socket side and the outside of the socket shall be wiped with a dry cloth. When there is oil stain on the surface, it must be wiped with acetone.
2、 Ultra wear-resistant composite pipe The section shall be flat, perpendicular to the pipe axis and chamfered; Before bonding, the insertion mark shall be drawn and the test insertion shall be carried out. The test insertion depth can only be 1/3-1/2 of the original depth. If the gap is too large, the bonding method is strictly prohibited.
3. When applying the adhesive, the inner side of the socket shall be applied first, and then the outer side of the socket. When applying the adhesive to the socket, an appropriate amount of it shall be evenly applied from the inside to the outside along the axial direction, without omission or excessive application (200g/m2).
4. After the application of the adhesive for the super wear-resistant composite pipe, the applied external force should be kept unchanged within 1 minute, and the straightness and position of the interface should be kept correct.
5. After the bonding of the super wear-resistant composite pipe is completed, the excess adhesive extruded shall be wiped out in time, and no force or forced loading shall be allowed during the curing time.
