Embodiment

[0015] Embodiment: process step one raw material preparation is to prepare quantitative length and be 100mm~200mm, width 2mm, thickness 0.6mm, the basswood wood silk that moisture content is about 8%; Configuration relative density is the magnesium chloride solution of 1.26, and magnesium chloride content is respectively 27.77%; prepare magnesite with a weight ratio of 1.5 to wood wool, and MgO and MgCl with a molar ratio of 5 to 6.43:1:10.4 to 13.2 2 and H 2 O mix.

[0016] Process step two mixing material is the prepared MgCl 2 The solution is evenly sprayed on the surface of the basswood wood, and then the magnesite is evenly sprinkled on the surface of the basswood to allow it to fully and evenly contact.

[0017] Process step three Slab paving is to spread the mixed material evenly in the forming frame with a length and width of 350mm, and apply a certain pre-pressure on the upper surface of the paving slab, so that the paving raw materials are pre-pressed .

Abstract

A steam pressure method for making the magnesite-wood shred board with light weight, short production period and high performance includes such steps as mixing magnesite as inorganic cementing material, wooden shreds as reinforcing material and MgCl2 solution, stirring, spreading, pre-pressing for shaping, and solidifying under a certain temp and steam pressure in a sealed press with steam generator.

Description

technical field [0001] The invention relates to a manufacturing process of light diamondwood silk board, especially the pressing process of autoclaving, and belongs to the technical field of inorganic adhesive wood-based board manufacturing process. Background technique [0002] Wood wool board is a board-shaped material made of natural wood and Portland cement as raw materials, which are processed, mixed and pressed by special processes. Lightweight magnesite wood wool board is a kind of wood wool board made of magnesite as the inorganic gelling material and wood materials such as wood reinforcement materials through different processes. Wood wool board usually has excellent physical and mechanical properties and good waterproof, fireproof, mothproof, heat and sound insulation properties, large format, nailable, sawable, and excellent construction performance such as secondary processing on the surface. This material is widely used as a building decoration material, which ...
