Putty-less plate processing technology and products of putty-less plates

Abstract

The invention relates to putty-less plate processing technology and products of putty-less plates. The putty-less plate processing technology is characterized by being implemented by the following steps of: (1) presetting a substrate; (2) coating a wet powder bonding layer on the substrate; (3) pressing, drying and polishing the substrate which is coated with the bonding layer to obtain finished plates of the putty-less plates. The processing technology has the advantages of saving working time, saving materials, reducing the entire cost of projects and overcoming the deflects caused by the operation of two project teams of the traditional calcium silicate plate installation and putty coating due to fully mechanized production. The products can be widely applied in work sites such as buildings, ships and tunnels.

Description

technical field [0001] The invention relates to a processing technique of a greasy-free board and its products, which can be widely used in construction sites such as buildings, ships and tunnels. Background technique [0002] Calcium silicate board is a new type of environmentally friendly building material. It is made of high-quality high-grade cement as the base material and reinforced with natural fibers. A new type of building and industrial board with excellent performance. Its products are fireproof, moisture-proof, sound-proof, moth-proof, and durable. It is an ideal decorative board for ceilings and partitions. After long-term testing in the market, it has been widely praised and widely used by industry users. The use in my country is showing a rapid growth trend. The national competent authority has listed calcium silicate board as a key development project. At present, the calcium silicate board market is mainly The annual growth rate exceeds 20%, and it is estima...

Problems solved by technology

[0003] The traditional method of operation is that the carpenter installs the silicate board and then the painter applies 3-5 layers of putty, which will consume a lot of man-hours and materials, and increase the cost burden of the project; and because the calcium silicate board is installed and the putty is scraped It is carried out by two project working groups. The interval between the two groups of operations can easily cause dirt on the surface of the calcium silicate board to be coated, which will affect the firmness of the putty after it is scraped and cause the coating to delaminate and make the quality of the project unsatisfactory. In addition, because the putty coating and scraping is purely manual operation, the smoothness of the coating surface cannot be effectively guaranteed, which greatly affects the aesthetics of the project. Moreover, the sandpaper has to be sanded many times due to the multiple coating and scraping of the putty, so a large amount of Dust causes environmental pollution
