Melt method
The hot melt method refers to the construction method of using flame heating to melt the hot melt adhesive at the bottom of the hot melt waterproof coil.
1, the grass-roots treatment: the first surface is clean, and the grass-roots should be solid, smooth, and clean; It Should be evenly coated with the base treatment agent, the requirement is not exposed bottom and leakage coating; After the surface is dry, roll material can be spread.
2, additional layer construction: Yin and Yang Angle, pipe root, eaves groove, deformation joints, and other parts should do additional layer processing, will be a pre-cut good size, the shape of the coil shop paste on the base.
3. Large surface construction: the coil is opened to release stress, and the coil is tiled according to the position of the plane elastic line; The hot melt tool is used for baking the lower surface and the base surface of the coil so that the asphalt on the surface of the coil is shiny to the molten state, and the coil is rolled while baking, and then rolled with a press roller to make it firmly bonded with the base.
4, lap treatment: the lap width of the coil should be 100mm, the lap area of the ring should be sealed separately, the same method of hot melting construction, the lap of the upper and lower coil to overflow hot melting modified asphalt as the degree, the width of about 3-5mm and uniform straight.
5. Closed water test: The closed water test shall be carried out according to the requirements of the construction scheme.
6, protection and isolation layer construction: the outer surface of the waterproof layer should be set up according to the relevant specifications or design requirements of the protective layer.
Hot glue method
1, grassroots treatment: the first surface is clean, grassroots should be solid, smooth, and clean.
2, additional layer construction: Yin and Yang Angle, pipe root, eaves groove, deformation joints, and other parts should do additional layer processing, and the coil pre-cut into the appropriate size, and shape.
3. Large surface construction: the non-curable coating is used for the composite construction of a hot-stick waterproof coil, and the thickness of the non-curable coating should meet the relevant specifications; Non - curing coating at the same time roll spread waterproof coil.
4, lap treatment: coil lap area should be sealed separately, the hot melt method for construction, the upper and lower coil lap to overflow asphalt strip as the degree.
5. Closed water test: The closed water test shall be carried out according to the requirements of the construction scheme.
6, protection and isolation layer construction: the outer surface of the waterproof layer should be set up according to the relevant specifications or design requirements of the protective layer.
