The invention relates to a building material production device and a matched production process flow, in particular to a gypsum foaming batten production device and a production process.
Background
The building partition wall batten is a product in the wall material industry, the product has standard specification and size, large block shape and good integrity, the length and the width of the board can be customized according to the requirements of construction environment, the mechanical production is convenient, and the production efficiency is high; the batten is easy to form and can be assembled in partition wall construction, and the construction efficiency is high; the industrial technology and economic index are easy to realize production industrialization, product standardization and specification size modularization, can obviously reduce the construction cost, and is very suitable for high-speed standardized construction of prefabricated residential buildings and light steel structure main buildings. The gypsum lath is a common building partition lath, which is produced in the middle and late stages of the last century, and the gypsum products at home and abroad mainly use natural gypsum at that time, but the technical development and application popularization of the gypsum lath are slow due to the three problems of low strength, water intolerance, high raw material cost and the like of the gypsum products. In 2007, with the environmental protection of various countries, the industrial by-product gypsum comes into the market successively, and China also has come out a mandatory industry policy to promote the comprehensive utilization of the industrial by-product gypsum, bringing pressure on digesting the by-product gypsum to relevant enterprises, and bringing business opportunity for producing gypsum laths by digesting the industrial by-product gypsum. The content of calcium sulfate dihydrate of the industrial byproduct gypsum is usually higher than 90 percent of that of common gypsum, the strength of the produced building gypsum is higher, and the problem of gypsum water resistance is better solved along with the technical progress, so that gypsum laths produced by taking the industrial byproduct gypsum with low cost or even negative cost as a raw material are returned to the market again and become one of the directions of the largest gypsum consumption, and in addition, the assembly type building is widely popularized in China, gypsum laths with various specifications and purposes are produced by transportation, and particularly, the partition wall type gypsum laths are gradually replacing the traditional non-bearing hollow brick partition wall or cement partition wall.
In order to reduce the dead weight of the batten and reduce the consumption of gypsum raw materials, the domestic gypsum batten is mainly produced by a hollow batten and adopting an extrusion forming process or a pouring core-pulling process, and the extrusion forming process has the defects that the production line speed is greatly restricted due to the limitation of gypsum setting time, and single high-yield production cannot be realized; the casting core-pulling production process has the defects that the adopted gypsum block production mode can only realize intermittent production, and a multi-component mold needs to be adjusted when the market requirements and specifications are different. The two production processes have lower production efficiency and capacity.
Based on the technical indexes of the gypsum lath, the gypsum foaming lath and the matched production process and equipment are invented, are particularly suitable for the plate with the surface layer thickness of the gypsum foaming lath being less than 1.5cm, can realize continuous and high-capacity production, and can produce products with various dimensions on the same equipment according to market demands without matched moulds.
The main technical advantages are as follows:
(1) the production process is originally created based on the gypsum foamed batten, the continuous three-layer pouring and integral forming production of the solid batten on the same production line are realized, the surface layer and the bottom layer adopt high-strength gypsum powder, the strength and the density are high, the middle layer adopts a foamed gypsum technology, the production efficiency and the qualification rate of products are greatly improved under the condition of meeting the mechanical property and the surface smoothness of the batten, and the production cost is reduced.
(2) The gypsum board is suitable for production of various raw materials, the raw materials can all adopt industrial byproduct gypsum, and the gypsum board can be produced into a physical foaming type, a chemical foaming type and a light material addition type batten, so that the function of one machine with multiple purposes is realized, the gypsum board particularly meets the relevant policies of national environmental protection, energy conservation, emission reduction, waste utilization and the like, and is novel gypsum building material equipment for realizing waste utilization, energy conservation, environmental protection and the like.
(3) The length and thickness of the plate can be adjusted by the equipment forming device according to the market demand, and the produced batten finished product has high strength, light weight and good surface smoothness.
