填充粉体对无机人造石性能的影响

Effect of Filling Powder on the Properties of Inorganic Artificial Stone

为研究填充粉体对无机人造石性能的影响,本文采用多种填充粉体掺入无机人造石配方中,研究石英粉、碳酸钙粉、白云石粉和氧化铝粉对无机人造石的抗折强度、吸水率、耐磨度、耐污值和线性膨胀系数等性能的影响。结果表明:掺入20 wt%石英粉体的无机人造石耐磨度值相比于空白样降低了74%,线性热膨胀系数增加了2倍。在0 wt%-20 wt%的掺量范围内,无机人造石的抗折强度随四种粉体掺量的增加而逐渐增大,吸水率逐渐减小,其中以碳酸钙作为填充粉体的无机人造石的抗折强度最高,防污性能最好,掺20 wt%碳酸钙粉的无机人造石抗折强度相比空白样增加了68.4%,吸水率降低了90.7%,耐污值降低了48%。因此可根据实际使用需求,使用不同的填充粉体来改善无机人造石的不同性能,拓宽无机人造石的应用范围。

In order to study the effect of filler powder on the properties of inorganic artificial stone,this paper mixed a variety of filler powder into the formula of inorganic artificial stone,and studies the effects of quartz powder,calcium carbonate powder,dolomite powder and aluminum oxide powder on the properties of inorganic artificial stone,such as bending strength,water absorption,wear resistance,stain resistance and linear expansion coefficient.The results show that the wear resistance of inorganic artificial stone mixed with 20 wt%quartz powder is 74%lower than that of the blank sample,and the linear thermal expansion coefficient is increased by 2 times.In the content range of 0-20 wt%,the bending strength of inorganic artificial stone gradually increases with the increase of the content of four kinds of powder,and the water absorption gradually decreases.Among them,the inorganic artificial stone filled with calcium carbonate powder has the highest bending strength and the best anti-fouling performance.Compared with the blank sample,the bending strength of inorganic artificial stone mixed with 20 wt%calcium carbonate powder increases by 68.4%,the water absorption decreased by 90.7%,and the pollution resistance value decreased by 48%.Therefore,according to the actual use needs,different filling powders can be used to improve the different properties of inorganic artificial stone and broaden the scope of application of inorganic artificial stone.
