打胶机常用密封胶有哪些?

发布时间:2019/07/25    发布人:

打胶机的密封剂选用的好,对产品的质量有很好的效果,下面双组份打胶机厂家就给大家介绍几种常见的密封胶种类!
Sealant selection of glue beater is good, which has a good effect on product quality. The following two-component glue beater manufacturers will introduce several common types of sealant to you!
1、丁基胶:
1. Butyl gum:
丁基胶是铝条式中空玻璃的首道密封,它是一种热融性胶,具有很低的水汽透过率(在中空玻璃胶中很低)较高的粘性,是铝条侧面和玻璃之间挡水汽的很有效屏障,但它需由专用机器加热、加压、挤出涂布在铝条两侧。
Butyl glue is the first seal of aluminium strip type hollow glass. It is a kind of hot melting glue with low water vapor permeability (very low in hollow glass glue) and high viscosity. It is a very effective barrier to water vapor between aluminium strip side and glass, but it needs to be heated, pressurized and extruded by special machine and coated on both sides of aluminium strip.
目前国产丁基胶厂家较多,但各家生产的胶,加热温度、压力均不尽相同,有的厂家的丁基胶甚至无法用机涂,常因有杂质而导致中断。这就需要用户选择质量好的产品,同时了解清楚它的使用要求。
At present, there are many domestic butyl rubber manufacturers, but the heating temperatures and pressures of the glues produced by each manufacturer are different. Some manufacturers'butyl rubber can not even be coated by machine, which often results in interruption due to impurities. This requires users to choose products of good quality and understand their requirements.
2、聚硫胶:
2. polysulfide gum:
广东11选5 聚硫胶是目前中空玻璃密封胶中用量很大的一种,聚硫胶具有良好耐油性、耐溶性及密封性。聚硫胶要有金属氧化物作为固化剂使用聚合,两种组份配比大约1:10,配合比例和均匀程度对效果发挥影响不是太大,故此胶可机涂也可人工手涂。

Polysulfide is one of the most widely used hollow glass sealants at present. polysulfide has good oil resistance, solubility and sealability. Polysulfur adhesives should be polymerized with metal oxides as curing agent. The ratio of the two components is about 1:10. The proportion and uniformity of the two components have little effect on the effect. Therefore, the adhesives can be coated by machine or by hand.
对聚硫胶的选用要求:双组份间色差分明;有效期在半年以上;抗紫外线能力强;有良好的流动性和固化弹性。
Requirements for selection of polysulfide adhesives: clear color difference between two components; validity period of more than half a year; strong anti-ultraviolet ability; good fluidity and curing elasticity.
3、硅硐胶
3. Silicon Tunnel Glue
硅硐密封胶具有结构性、耐老化性及抗紫外线性能,但它的致使弱点是水汽透过率高。故而硅硐胶适用于在光照强、环境差的地方,如玻璃幕墙等,同时必须使用丁基胶做一道密封。硅硐胶,在过去,我国长期依赖进口,现国家经贸委专门成立了硅硐胶领导小组,对结构胶进行安全认证。目前国内已有多家企业通过认证。
Silicon tunnel sealant has structure, aging resistance and ultraviolet resistance, but its weakness is high water vapor permeability. Therefore, silica tunnel gel is suitable for places with strong illumination and poor environment, such as glass curtain wall. At the same time, butyl rubber must be used to make a seal. In the past, China relied on imports for a long time. Now the State Economic and Trade Commission has set up a leading group of silica gel to certify the safety of structural gel. At present, many enterprises in China have passed the certification.
