Neutral Silicone Sealant Kuumbwa

Neutral silicone sealants inonyanya kuumbwa nesilicone polymers, fillers, crosslinkers, uye catalysts. Silicone polymers inoumba chikamu chikuru, chingangoita 70%-80%, ichipa yekutanga chisimbiso uye ma bonding zvivakwa. Mafirita akadai secalcium carbonate uye silica anobatsira angangoita gumi-20% kusimudzira simba remagetsi echisimbiso uye kuderedza mitengo. Crosslinkers uye catalysts vane basa rekurapa kwechisimbiso maitiro, ane mazinga emukati angangoita 1% -5% uye 0.1% -1%, zvichiteerana. Iyo Shin-Etsu neutral silicone sealant inopihwa muchitoro chedu ine yakanakisa tembiricha yekudzivirira (-50 dhigirii kusvika 250 dhigirii) uye inorapa zvizere mushure memaawa makumi maviri nemana pakamuri tembiricha. Iine kuoma kwe50 Shore A uye simba rekugera re 1.3 MPa, zvichiita kuti ive yakakodzera kuchengetedza zvikamu zvemagetsi uye kupa chisimbiso chisina mvura.
