Cov Kev Txwv rau cov kua qaub iav silicone sealant: Cov kua qaub silicone sealant yuav xeb lossis tsis tuaj yeem khi tooj liab, tooj dag (thiab lwm yam hlau uas muaj tooj liab), magnesium, zinc, hlau electroplated (thiab lwm yam hlau uas muaj zinc), thiab nws raug pom zoo kom ua cov masonry rau hauv cov khoom thiab tsis txhob siv cov kua qaub iav silicone sealant rau ntawm cov hlau carbide substrate. Siv cov kua qaub iav silicone sealant.
Rau cov ntaub ntawv ua los ntawm methyl methacrylate (PLEXIGLAS), polycarbonate, polypropylene, polyethylene thiab TEFLON (Teflon, polytetrafluoroethylene). Nws yuav tsis tau txais kev nplaum zoo thiab kev sib haum xeeb zoo. Acid iav silicone sealant tsis haum rau kev sib txuas uas txav ntau dua 25% ntawm qhov dav sib koom ua ke. Ordinary acid iav silicone sealant yuav tsum tsis txhob siv rau ntawm cov iav qauv (tshwj tsis yog acid structural silicone sealant). Tsis tas li ntawd, nws yuav tsum tsis txhob siv qhov twg muaj kev puas tsuaj thiab qhov tsis zoo. Siv acid iav silicone sealant. Qhov kub ntawm qhov chaw ntawm cov khoom siv hauv paus ntawm silicone acid iav silicone sealant tshaj 40 ℃ thiab nws tsis haum rau kev tsim kho. Kev txwv ntawm neutral silicone sealant: Neutral silicone sealant tsis haum rau kev sib dhos iav qauv; nws tsis haum rau kev tsim kho yog tias qhov kub ntawm lub substrate tshaj 50 ° C. Silicone structural adhesive kev txwv: Tsuas yog rau phab ntsa ntaub thaiv tag nrho, silicone structural sealant tsis tuaj yeem txhaj rau ntawm qhov chaw tsim kho; qhov kub ntawm qhov chaw ntawm silicone structural adhesive tsis haum rau kev tsim kho yog tias qhov kub ntawm qhov chaw substrate tshaj 40 ° C. Cov xwm txheej khaws cia thiab lub sijhawm khaws cia Cov roj hmab silicone sealant yuav tsum khaws cia rau hauv qab 27 ° C hauv qhov chaw txias thiab qhuav. Cov roj hmab silicone sealant zoo uas muaj kua qaub iav tuaj yeem lav tau ntau dua 12 lub hlis, thiab cov roj hmab silicone sealant dav dav tuaj yeem khaws cia ntau dua 6 lub hlis; cov roj hmab silicone sealant tsis muaj zog thiab cov kua nplaum tuaj yeem lav tau ntau dua 9 lub hlis. Yog tias lub raj mis tau qhib lawm, thov siv nws kom tas hauv lub sijhawm luv luv; yog tias cov roj hmab silicone sealant tsis siv tag, lub raj mis yuav tsum kaw. Thaum siv nws dua, lub qhov ncauj raj mis yuav tsum tau unscrewed kom tshem tawm tag nrho cov blockages lossis hloov lub qhov ncauj raj mis.
