Embodiment

[0032] Such as figure 1 As shown, this embodiment introduces a simple method for making straw boards, which includes the following steps:

[0033] Step S1 is the pretreatment of straw. The pretreatment of straw includes five processes of cleaning, cutting, drying, crushing and drying again. First, crop straw refers to the remaining stems after mature threshing of grasses such as rice, wheat, and corn For the leaf part, put the collected crop stalks into a large pool for multiple times of water soaking to wash the dust on the crop stalks; secondly, use an organic solvent such as alcohol to clean off the oil-soluble dirt on the crop stalks such as grease; , use a hay cutter to cut various crop straws into 2-3cm small pieces; thirdly, put the cut into small pieces of crop straws in a straw dryer and dry them until the moisture content is 20-30%; The dried straw segments are put into a straw grinder and crushed into straw powder; fifthly, the straw powder is put into a straw drye...

Abstract

The invention discloses a method for manufacturing a straw board. The method comprises the following steps that S1, preprocessing is carried out on straw, namely the collected crop straw is subjectedto the operation of cleaning, cutting, drying, crushing and re-drying; S2, mixing is carried out on materials, namely, plant powder is added into dried straw powder and is used for filling gaps and uniformly mixing to form mixed powder; S3, gluing is carried out, namely viscose is added into the mixed powder, the mixture is uniformly mixed to obtain a colloidal mixture, and the mass ratio range ofthe mixed powder to the viscose in the colloidal mixture is 15:1 to 10:1; S4, pressing forming is carried out, namely, the colloidal mixture is poured into a mold, and then pressure is applied to press the colloidal mixture into the straw board; and S5, drying is carried out on a finished product, namely, the formed straw board is dried at the temperature of 70-85 DEG C. According to the method,the crop straw is processed and reutilized to manufacture the straw board through the steps, so that the environment problem encountered in the process of treating the straw can be avoided, and wasteutilization is realized on the straw.

Description

technical field [0001] The invention relates to the technical field of artificial boards, in particular to a method for making straw boards. Background technique [0002] The output of rural straw, especially crop straw, in my country is huge. The straw produced in the last century can be used as firewood, so it enters the environmental cycle very well. series of questions. During the summer harvest and autumn and winter every year, a large amount of wheat and crop straws burned in the fields produce a large amount of thick smoke, which not only aggravates the serious environmental problems caused by the smog, but also poses safety hazards and causes fires. Therefore, in order to solve various environmental problems caused by burning straw, two ways of digesting straw have been developed: first, the straw is returned to the field through the stomach, and the straw has been cut, bundled, transported, guillotined, and ammoniated. As animal husbandry feed, livestock manure is ...
