关于门窗玻璃胶的十问十答

所属分类:技术文章 点击次数:326 添加时间:2019-07-03

1.中性透明胶变黄是什么原因?
  答:中性透明胶变黄是胶浆本身存在缺陷,主要是由中性胶内的交联剂和增粘剂引起的,原因是这两种原料带有“胺基”,胺基是极容易引起发黄的,很多进口名牌的玻璃胶也是因此有变黄的现象。

  2.中性瓷白胶为何会有变粉红的现象?有些胶固化后一个星期又变回瓷白?
  答:醇型的中性胶可能有这种现象出现,那是生产原料钛铬合物引起的。

  3.有些国产透明胶,打出来五天后变瓷白颜色?中性绿色胶施工后变瓷白颜色,为什么?
手赚咖  答:这也应该属于原材料选择及验证上的问题。因为有些国产胶里加有增塑剂,易挥发,而有些胶内加有较多补强填料,当增塑剂挥发,胶条因收缩而被拉伸,现出填料颜色(中性胶所有填料本身是白色的)。

  4.为什么镜子背面打上玻璃胶,一段时间后,镜面出现花斑或胶的痕迹?
  答:市场上镜子通常有三种不同的背面镀层:水银、纯银和铜。

  5.有些玻璃胶打出来时有盐粒般大小的粒状,而固化后有些粒状又会自动化解,为什么?
手赚咖  答:这是选择胶的原材料配方上的问题。因为某些胶内含有的交联剂,在温度较低的环境下有结晶现象,交联剂在胶瓶内凝结,打出来后便会看见有盐粉粒般大小的粒状,但它慢慢会溶化的,所以固化后粒状又会自动化解。这种情况对胶的质量影响不大。出现此情况,主要是受低温影响比较大。

  6.有些国产胶打在玻璃上,7天仍未干胶,什么原因?
手赚咖  答:这种情形多数在天冷时候出现。

  8.为什么夏天有的中性胶打在混凝土和金属窗框的结合部位固化后会出现很多气泡,而有的又不会?是不是质量的问题?为什么以前没有类似现象出现?
  答:很多品牌的中性胶都有过类似现象出现,但其实并不是胶的质量问题。中性胶有醇型和酮肟型两种,而醇型胶在固化过程中所含的甲醇会释放出气体(甲醇在50℃左  右开始挥发),特别遇到太阳直射或高温反应更强烈。

  9.如何做相容性测试?
手赚咖  答:从严格意义上讲,做胶粘剂和建筑基材间的相容性测试应该到国家承认的建筑材料测试部门进行,但在这些部门送检得到结果的周期较长,费用高。

  10.酸性胶用在水泥上为什么很容易脱落?
  答:酸性胶在固化时产生醋酸,会与水泥、大理石、花岗岩等碱性材料的表面发生反应,形成一种白垩状的物质,从而引起脱落。
