Some households used plastic flooring when decorating and decorating the living room. After paving, they found that the surface was flat and the surface was wavy. The main reason for this phenomenon is that the following points are not noted in the construction:
(1) The surface of the base layer has poor flatness and unevenness.
(2) When the operator applies the adhesive, the gesture is light and heavy, so that the scratched adhesive has a distinct wave shape. When the plastic floor is pasted, the diluent in the adhesive has evaporated, the fluidity of the colloid is poor, and it is not easy to be smoothed when pasted, so that the surface layer is wavy.
To prevent this quality problem, you must:
(1) Strictly control the surface flatness of the adhesive base layer, and flatten the surface with a degree of unevenness greater than ±2 mm.
(2) Scratch the adhesive with a toothed scraper to make the thickness of the adhesive layer thin and uniform. When scraping, the direction of the coating on the adhesive surface of the base layer and the plastic plate should be intersected vertically and horizontally, so that when the surface layer is laid, the adhesive layer on the adhesive surface is uniform.
(3) The construction temperature should be controlled at 15 to 30 degrees, and the relative humidity should be no higher than 70%.
