A bathtub production process

Abstract

The invention belongs to the technical field of sanitary ware, and discloses a bathtub production technology. The bathtub production technology comprises the following steps of heating to soften an acrylic sheet, putting the softened acrylic sheet on the mold cavity mouth of a bathtub mould having a clamping piece structure and fixing the softened acrylic sheet, performing plastics sucking moulding, and manufacturing an inner tub and an outer tub by using respective moulds different in mold cavity shape; spraying reinforcing fibers to the outer tub and the inner tub; laying reinforcing platesto the outer surface of the tub bottom and the outer surface of the side wall of the inner tub, and laying the reinforcing plates to the inner surface of the side wall of the outer tub; forming a drain hole and a spillway hole in respective preset positions of each of the inner tub and the outer tub; cutting off unnecessary tub mouth hemlines of the inner tub and the outer tub; butting tub mouth hemlines of the inner tub and the outer tub in manner of matching, and laying fibers to butt edges; pouring resin grout and white paste to the bottom parts of the tub mouth hemlines of the inner tub and the outer tub for reinforcement; and sticking polyurethane ground feet to the bottom part of the outer tub, and trimming the ground feet to make the ground feet parallel and level with the bottom part of the outer tub. The technology disclosed by the invention is simple in flow, and the obtained finished product bathtub is higher in stability and better in texture.

Description

technical field [0001] The invention relates to the technical field of sanitary ware, in particular to a bathtub production process. Background technique [0002] Acrylic plastic bathtubs are welcomed by consumers because of their advantages such as not easy to deform, good thermal insulation performance, and easy to clean. The existing acrylic plastic bathtub has a cumbersome production process, and the finished bathtub is relatively light in weight, which tends to appear lacking in texture, not stable enough, and slightly insufficient in stability. Moreover, due to technological limitations, it is impossible to prepare finished bathtubs with concavo-convex patterns. In addition, the existing production process cannot preliminarily test the quality of the bathtub during the process. The quality inspection can only be carried out after the complete finished bathtub is obtained. If problems are not found in time, it is easy to cause waste of raw materials. [0003] Therefor...
