“黄金有价,奇石无价”,这句顺口溜在“石友”中流传甚广。从上世纪9年代起,奇石收藏和交易渐渐火热起来。奇石成为收藏家的新宠,也成为了一个很有前景的投资项目。实际上,收藏奇石并不是*近才兴起的。早在石器时代,我们的祖先就不满足于石器的实用功能了,还懂得收集美丽的石头作为吉祥物来装饰自己。在封建王朝,宋徽宗建“垠岳”造“寿山”,广征天下奇石,引发了一次奇石采集的热潮。至清朝乾隆皇帝御笔亲书灵璧石为“天下奇石”,则更是挑起了灵璧奇石收藏高峰。磁县变量泵供应A10VSO100DFR1/32R

下面我们主要谈腻子层的龟裂几个问题。腻子层裂缝，腻子涂刮层过厚产生龟裂，一般腻子厚度1-2mm，一般不过3mm。有的内外墙基面平整度误差多达3-5公分，如果全用腻子粉找平肯定龟裂。应该用砂浆找平，误差越大要求砂浆的砂越粗，基层用砌筑砂浆，加上柔性砂浆找平以后，才能满批腻子。图二十八图二十九无机粘结剂（灰钙粉、水泥）添加量过多，强度过大也会造成裂缝，一般在内外墙防水腻子出现裂纹现象，灰钙粉、水泥添加量过5%以上造成腻子强度过大，饰面硬脆，易产生龟裂纹。
