打膠機的密封劑選用的好,對產品的質量有很好的效果,下面雙組份打膠機廠家就給大家介紹幾種常見的密封膠種類!
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、丁基膠:
1. Butyl gum:
丁基膠是鋁條式中空玻璃的首道密封,它是一種熱融性膠,具有很低的水汽透過率(在中空玻璃膠中很低)較高的粘性,是鋁條側面和玻璃之間擋水汽的很有效屏障,但它需由專用機器加熱、加壓、擠出涂布在鋁條兩側。
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.
目前國產丁基膠廠家較多,但各家生產的膠,加熱溫度、壓力均不盡相同,有的廠家的丁基膠甚至無法用機涂,常因有雜質而導致中斷。這就需要用戶選擇質量好的產品,同時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、聚硫膠:
2. polysulfide gum:
广东11选5 聚硫膠是目前中空玻璃密封膠中用量很大的一種,聚硫膠具有良好耐油性、耐溶性及密封性。聚硫膠要有金屬氧化物作為固化劑使用聚合,兩種組份配比大約1:10,配合比例和均勻程度對效果發揮影響不是太大,故此膠可機涂也可人工手涂。

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.
對聚硫膠的選用要求:雙組份間色差分明;有效期在半年以上;抗紫外線能力強;有良好的流動性和固化彈性。
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、硅硐膠
3. Silicon Tunnel Glue
硅硐密封膠具有結構性、耐老化性及抗紫外線性能,但它的致使弱點是水汽透過率高。故而硅硐膠適用于在光照強、環境差的地方,如玻璃幕墻等,同時必須使用丁基膠做一道密封。硅硐膠,在過去,我國長期依賴進口,現經貿委專門成立了硅硐膠領導小組,對結構膠進行安全認證。目前國內已有多家企業通過認證。
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.
