| 凝固性粘合剂主要指聚氨酯胶粘剂、高分子改性水泥涂料等。凝固性粘合剂干固后，与卷材表面无纺布铆固粘合。 Setting adhesive mainly refers to polyurethane adhesive, polymer modified cement coating, etc. After the solidified adhesive is dried, it is riveted and bonded with the non-woven fabric on the surface of the coil. 粘接机理：线性低密度聚乙烯（主防水层）表面复合无纺布加糙，在卷材表面形成网状空隙结构，使其具有可粘接性能。当卷材表面无纺布与粘合液接触时，无纺布纤维切向布置使粘合易于浸入，粘合液浸入无纺布网状孔隙，形成机械铆固作用，使卷材与卷材或基层牢牢地粘接在一起。 Bonding mechanism: the surface of linear low density polyethylene (main waterproof layer) is roughened by composite non-woven fabric, forming a network gap structure on the surface of the coil, so that it has adhesive properties. When the non-woven fabric on the coil surface contacts with the adhesive solution, the tangential arrangement of the non-woven fabric makes the adhesive easy to be immersed, and the adhesive solution is immersed into the mesh pores of the non-woven fabric, forming a mechanical riveting effect, so that the coil and the coil or the base layer are firmly bonded together. |
