Low-cost environment-friendly full-body white brick and preparation method thereof
The invention provides a low-cost environment-friendly full-body white brick. According to the low-cost environment-friendly full-body white brick, pyrophyllite and diopside serve as main raw materials, a potassium-sodium system is changed into a calcium-magnesium system, the use amount of high-cost ball clay and high-whiteness potassium-sodium feldspar is reduced, a zirconium silicate brighteningagent in a traditional formula is removed, a firing temperature is reduced, and the whiteness of a produced product is 53 degrees or above; due to the melting assisting effect of the calcium-magnesium system, the firing temperature can be reduced, and fuel cost is synchronously saved, so production cost is reduced; since the pyrophyllite and the diopside are used as the main raw materials, the problem that a firing range is narrowed occurs, the temperature amplitude range of a high-temperature area is 3 DEG C or above in the prior art, and the temperature amplitude range of the high-temperature area is 3 DEG C or below in the invention; and gas is exhausted completely before a brick surface is melted to a flat state by optimizing a firing curve and lengthening an oxidation zone, and at the moment, pores do not exist in the brick surface of the obtained finished brick, dirt is not prone to hiding on a brick surface, the antifouling effect of the brick surface of the finished brick is greatly improved, and the problem that a conventional calcium-magnesium full-body white brick is poor in antifouling capacity can be effectively solved.
本发明一种低成本且环保的通体白砖，以叶蜡石、透辉石为主原料，由钾钠系变为钙镁系，降低高成本的球土及高白钾钠长石的用量，去掉了传统配方中的硅酸锆类增白剂，同时降低了烧成温度，产出的产品白度在53度以上，由于钙镁系的助融作用，烧成温度会降低，同步节约了燃料成本，从而使生产成本降低；以叶蜡石、透辉石为主原料，此时会面临烧成范围变窄的问题，以前的高温区温度幅度范围在3摄氏度以上，现在高温区温度幅度范围在3摄氏度以内，通过优化烧成曲线，拉长氧化带，在砖面融平之前将气体排完，此时得到的成品砖的砖面不存在毛孔，砖面不再易于藏污纳垢，极大提升成品砖砖面的防污效果，能有效解决钙镁系通体白砖防污能力差的问题。
