问:我们抛光玻璃一般总是把抛光模套在玻璃上,并在它们中间加上抛光粉和水。如果不用水,而用其它的液体行不行?是不是因为水最便宜的缘故? 答:要进行理想的,高效率的镜面抛光,一定得用水。这并不单纯是因为水最便宜,更主要的是因为玻璃在水里会发生水解作用。通俗地讲,就是玻璃泡在水里会溶化掉。我们先来看一个实验:将粗磨下来的B_aK_3、ZF_5玻璃粉末,经过仔细地脱脂、清洗后,分别倒入盛有蒸馏水的烧杯中。仔
Q. We always polish the glass on the glass, with polishing powder and water in between. If you do not use water, but do not use other liquids? Is it because of the cheapest water? A: To make the ideal and efficient mirror polishing, you must use water. This is not simply because the water is the cheapest but more importantly because the glass is hydrolyzed in the water. In short, glass bubbles dissolve in the water. Let us first look at an experiment: the coarsely ground B_aK_3, ZF_5 glass powder, carefully degreased, washed, respectively, into a beaker filled with distilled water. kid
