(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

       可預涂微膠囊MS密封膠是MS密封膠系列的新品種,它的應用使螺紋件機械化涂布變成了現實,提高了生產效率。因此,被國內外汽車制造廠家廣泛采用。美國樂泰公司的系列MS密封膠技術水平在世界居領先地位,一直引導著我國MS密封膠技術的發展。國內開發出水基型和溶劑型中等強度的微膠囊MS密封膠品種,但由于外觀和性能上同樂泰同類品相比差距較大,在機械涂膠應用上受到一定限制。為了解決汽車工業對高強度微膠囊MS密封膠的需求,國內相關科研單位與汽車廠家進一步攜手聯合開發出水基型雙組分高強度微膠囊產品,并成功地將其應用到汽車螺紋件的鎖固上,質量達到國外同類產品水平,且具有一定的價格優勢,提升了我國微膠囊MS密封膠的應用和汽車制造的技術水平。

       熱熔/MS密封膠帶在車身特定部位焊裝成型工藝中,較之PVC塑溶膠而言,采用預先成型的熱熔膠帶進行焊縫密封,在保證焊縫外表美觀方面優勢非常明顯:在大面積車身裝配過程中,傳統工藝仍以焊接、鉚接等為主要方式。在國外已采用高強度MS密封膠帶,這種工藝不僅可以滿足結構性粘接的質量要求,且能保證車身外表平整美觀,達到傳統工藝無法實現的減震、降噪、密封、防銹的作用。但國內尚未發現能滿足使用要求的熱熔MS密封膠帶。

       單組分聚氨酯決速濕固化風擋玻璃MS密封膠的開發,是我國追趕世界先進水平的一大成果,但使用時MS密封膠需要配套的清洗劑、玻璃膝面底劑,才能保證足夠的粘接強度,而且固化速度較慢,在車窗玻璃裝配過程中,需使用MS密封膠帶或裝配夾具協助固持定位、工藝繁瑣。為了克服這種不足,開發瞬時定位的單組分聚氨醋擋風玻璃MS密封膠應是膠粘齊」研究下一步努力的方向。根據國外報道,這種MS密封膠一般通過配備加熱涂布裝置,使微熱涂布膠料對被粘物立刻產生較高的初粘強度,完成擋風玻璃的定位,然后逐步達到完全固化,既簡化了工藝,又方便了操作。www.16878m.com
