Manufacturing method of material for preventing excessive water absorption of surface of water-resistant gypsum board
The invention discloses a manufacturing method of a material for preventing excessive surface water absorption of a water-resistant gypsum board, and relates to the technical field of self-use charging equipment. The manufacturing method specifically comprises the following steps of: step 1, selecting pea starch and corn starch as raw materials, and mixing the pea starch and the corn starch in proportion for later use; and step 2, blending the prepared raw materials until the water content is 20%, then adding 0.1% of oxalic acid and 1% of stearic acid based on starch dry basis, and then mixing the added materials with the starch to achieve a homogeneous phase; Through modification treatment of the starch, the viscosity of the starch is reduced and the fluidity of the starch is enhanced while the lipophilicity of the starch is increased and the anti-water-absorption function is enhanced, so that good growth of gypsum crystals is effectively protected before the gypsum board is not coagulated, the water absorption of a gypsum board product in a later humid environment is reduced, and the service life of the gypsum board is effectively prolonged.
本发明公开了一种解决耐水石膏板防表面吸水过量的材料制作方法,涉及自用装料设备技术领域,具体包括以下步骤:步骤一、首先我们选用豌豆淀粉、玉米淀粉为原料,并将豌豆淀粉和玉米淀粉按比例进行混合后备用;步骤二、将准备好的原料调成水份含量为20%,然后加入淀粉干基的0.1%的草酸1%硬脂酸再与淀粉混合达到均相。本发明通过淀粉的改性处理,增加淀粉的亲油性,增强抗吸水功能的同时,降低其粘度,增强其流动性,在石膏板未凝结之前,有效保护石膏晶体的良好生长,使石膏板制品在后期潮湿的环境下吸水量减少,有效增加石膏板的使用寿命。
