Problems solved by technology

[0002] Now industry, agriculture, construction, decoration and other fields consume a lot of cement, sand and gravel boards, building bricks, wood boards, squares, strips, etc., need to consume a lot of cement, sand and wood, The production of these products consumes a lot of raw materials and energy, pollutes the environment, and has high production costs. On the other hand, the vast areas of northern rural areas produce a large amount of corn and sorghum stalks every year. Farmers burn them in the field before planting in spring, which is not only in vain. waste its resources and pollute the air

Embodiment Construction

[0020] The production method is as follows:

[0021] 1. Selection of straw material and processing of straw skin: See Figures 1 and 2. Take corn and sorghum stalks that are mature, thick and upright after autumn, and cut up 72 cm long and uniform straw, remove the outer leaves, peel off the outer skin, and clean the inner flesh , cut off the unequal width from the tip to make it a strip-shaped straw skin 1 with a width of more than 3cm (the minimum value of sorghum stalks), or a width of more than 6cm (the minimum value of corn stalks), and a uniform length of 72cm. The raw materials to be processed are convenient for mechanized large-scale processing.

[0022] Selection of adhesives: Choose polymer resin adhesives or adhesives with the same performance that meet national regulations and are green and environmentally friendly, formaldehyde-free or formaldehyde-free.

[0023] Selection of thin paper: Its function is to adjust the bonding gap and strengthen the bonding force. G...

Abstract

A technology for manufacturing brick, board, or bar with the stalks of corn and sorghum includes such steps as cutting short by needed length, removing leaves and pitch, spreading a paper on the bench, spraying adhesive, spreading the pre-treated stalks and spraying adhesive layer by layer, pressing, solidifying and cutting by required sizes.

Description

technical field [0001] The invention belongs to a method for making bricks, boards and strips. Background technique [0002] Now industry, agriculture, construction, decoration and other fields consume a large amount of cement, sand and gravel boards, building bricks, wood boards, squares, strips, etc., which need to consume a lot of cement, sand and wood. The production of these products consumes a lot of raw materials and energy, pollutes the environment, and has high production costs. On the other hand, the vast rural areas of the north produce a large amount of corn and sorghum stalks every year. Farmers burn them in the field before planting in spring, which is not only in vain. It wastes its resources and pollutes the air. Contents of the invention [0003] The purpose of the present invention is to provide a method for making bricks, boards and strips by using corn or sorghum stalks. The raw material resources are abundant, the production method is simple, environm...
