Problems solved by technology

Therefore, the fiber requirements are high, because the fiber cost accounts for 30-40% of the entire material cost, resulting in high cost
In addition, the manufacturing process is complicated and the efficiency is low
In addition, it is impossible to make multi-layer composite boards, and it is impossible to make boards with ribs that are resistant to bending and bending

Embodiment 1

[0039] see figure 1 , in an embodiment of the present invention, a process for fabricating a fiber-reinforced composite sheet with ribs by paving method includes the following steps:

[0040] (1) Stir the base material evenly in the base material mixing station 13, then put it into the primary paver 14, and spread the base material in the mobile mold to form a layer of base material layer 1;

[0041] (2) Stir the fabric evenly in the fabric mixing station 23, then put it into the secondary paver 24, and spread the fabric flat on the bottom material layer 1, and spread it into a layer of fabric layer 2;

[0042] (3) Then, the bottom material layer 1 and the fabric layer 2 are sent into the initial curing kiln 4 by a conveyor belt, and steam initial curing is carried out. The steam initial curing condition is: temperature 50-100 ° C, time 2-5 minutes, so that the material is initially set to It is beneficial to move when stacking, and stack the plates after leaving the kiln;

Abstract

The invention discloses a process for manufacturing a fiber reinforced rib-containing composite board by adopting a spreading method. The process comprises the following steps: uniformly mixing base materials in a base material mixing station, then putting the mixture into a primary spreading machine, flatly spreading the base materials in a mobile mold and spreading the base materials to form a base material layer; putting reticular or strip-shaped ribs made of metallic or nonmetallic materials on the base material layer; uniformly mixing face materials in a face material mixing station, putting the mixture in a secondary spreading machine, flatly spreading the face materials on the base material layer and spreading the face materials to form a face material layer; conveying the base material layer and the face material layer into a primary curing kiln for steam primary curing and then performing stacking treatment and high-pressure steam curing to obtain the fiber reinforced rib-containing composite board. Since the process is different from a beater addition process and a flow-on process and the requirement on the adsorption of fibers is low, coarse fibers can be used, a great amount of straw such as wheat straw, rice straw and cotton stalks can be used as raw materials and the problem of a great amount of agricultural wastes is solved. Wastewater produced during manufacturing of straw fibers can be used for manufacturing slurry. Accordingly, no waste is produced in the entire process.

Description

technical field [0001] The invention relates to a manufacturing process of a composite plate, in particular to a process for fabricating a fiber-reinforced composite plate with ribs by a paving method. Background technique [0002] Fiber-reinforced calcium silicate board is a kind of lightweight board that is vigorously developed by countries all over the world. The lightweight composite wallboard made of it integrates waterproof, moisture-proof, sound insulation and heat insulation, and has become widely used in construction projects in developed countries today. A new type of wall material. Calcium silicate board is a new type of board made of siliceous materials and calcium materials and adding appropriate amount of reinforcing materials through pulping, molding, autoclave curing, drying, sanding and post-processing. As a new type of environmentally friendly building material, fiber reinforced calcium silicate board not only has the functions of traditional gypsum board,...
