Ukungathathi hlangothi kweSilicone sealant Composition

I-Silicone sealants engathathi hlangothi ngokuyinhloko yenziwe nge-silicone polymers, fillers, crosslinkers, kunye ne-catalysts. Iipholima zeSilicone ziquka elona candelo likhulu, malunga ne-70%-}80%, ebonelela ngeyona nto iphambili yokutywina kunye neempawu zokudibanisa. Izihluzi ezifana ne-calcium carbonate kunye ne-silica zinegalelo malunga ne-10% -20% ukunyusa amandla omatshini we-sealant kunye nokunciphisa iindleko. I-Crosslinkers kunye ne-catalysts zijongene nenkqubo yokunyanga i-sealant, kunye namanqanaba omxholo malunga ne-1% -5% kunye ne-0.1% -1%, ngokulandelanayo. I-Shin-Etsu engathathi hlangothi ye-silicone sealant enikezelwa kwivenkile yethu inokumelana nokushisa okuphezulu (-50℃ukuya kwi-250 degree) kwaye iphilisa ngokupheleleyo emva kweeyure ze-24 kwiqondo lokushisa. Inobulukhuni be-50 Shore A kunye namandla okucheba i-1.3 MPa, okwenza ukuba ifaneleke ukukhusela amacandelo e-elektroniki kunye nokubonelela ukutywinwa kwamanzi.
