Problems solved by technology

Although the above process adopts the impregnation process, it is mainly to impregnate the raw materials, and then process them according to the general paving process, so the produced boards have the defects of not being fireproof and not having enough strength.

Abstract

The invention discloses a dipping and rolling process for a plant fiber fireproof board, comprising the following steps: A. using a paving machine to make a slab with plant fiber silk as a raw material through the paving process, and the density of the slab is 0.1 to 0.2g / cm3; B. Soak the slab in the inorganic gelling slurry with a mass percentage concentration of 50% to 70%; C. Roll the soaked slab; D. Make the rolled slab through curing and drying, etc. into plant fiber fireproof panels. The inorganic gelling slurry is a slurry formed by mixing magnesium chloride, magnesium oxide and water. Due to the above-mentioned production process, not only the board has the characteristics of light weight, anti-corrosion, easy processing, and low cost, but also adds fireproof performance, and at the same time increases the strength of the board; the use of this process also solves the problem of long fiber winding in At the same time, the phenomenon of knotting or entanglement occurs, thereby ensuring the production efficiency of the board and improving the quality of the processed board.

Description

technical field [0001] The invention relates to a production process of a fiber board, in particular to a production process of a fireproof board which is processed and produced with plant fibers as raw materials. Background technique [0002] The current production process of various cement fiberboards is basically the method of mixing, mixing, pouring, and injection molding. The material is formed by fully combining, laying, and pouring molds. However, for long fibers, the above-mentioned production process is not suitable, because long fibers are easily entangled during the process of laying long fibers using the above-mentioned process. , There is a phenomenon of knotting or entanglement, which not only affects the production efficiency of the sheet, but also affects the quality of the processed sheet. [0003] In addition, the Chinese Patent Office has published the patent application document "Production Method of Reed Fiberboard" with the patent application number of...
