Cov roj hmab silicone sealant zoo li thaum ub siv dav hauv txhua hom tsev. Cov ntaub ntawv kho kom zoo nkauj sab hauv thiab sab nraud ntawm phab ntsa thiab lub tsev tau txais kev lees paub los ntawm txhua tus.
Txawm li cas los xij, nrog rau kev txhim kho sai ntawm kev siv cov silicone sealant hauv cov tsev, teeb meem cuam tshuam rau kev ua tau zoo thiab kev nyab xeeb ntawm cov tsev sib xws maj mam tshwm sim.
Yog li ntawd, nws yog qhov tsim nyog los txhawb kev nkag siab txog kev ua tau zoo ntawm cov khoom siv silicone sealant.
Cov khoom siv silicone sealant yog ua los ntawm polydimethylsiloxane ua cov khoom siv tseem ceeb, ntxiv los ntawm tus neeg sawv cev crosslinking, filler, plasticizer, coupling agent, catalyst hauv lub tshuab nqus tsev sib xyaw ua ke, thiab tom qab ntawd cov dej hauv huab cua yuav tsum tau khov kho kom zoo li cov roj hmab silicone elastic.
Cov roj hmab silicone yog ib hom iav thiab lwm yam khoom siv rau kev sib txuas thiab kaw cov ntaub ntawv. Muaj ob pawg tseem ceeb: silicone sealant thiab polyurethane sealant (PU).
Cov roj hmab silicone muaj ob hom acetic thiab neutral (cov roj hmab nruab nrab yog muab faib ua: cov roj hmab pob zeb, cov roj hmab tiv thaiv kab mob fungal, cov roj hmab hluav taws, cov roj hmab kav dej, thiab lwm yam); Xws li OLV 168 thiab OLV 128, lawv muaj daim ntawv thov sib txawv.
OLV168 acetic silicone sealant ceev vulcanization ntawm chav tsev kub, thixotropic, tsis muaj dej ntws, zoo tiv taus kev laus, tsis kam roj, tsis kam dej, dilute acid tsis kam, dilute alkali tsis kam, siab thiab qis kub tsis kam, tuaj yeem siv rau hauv qhov ntau ntawm -60 ℃ ~ 250 ℃, muaj kev sib khi zoo, tiv taus kev poob siab thiab cuam tshuam.
Acetic feem ntau yog siv rau kev sib txuas dav dav ntawm iav thiab lwm yam khoom siv hauv tsev. Neutral kov yeej cov yam ntxwv ntawm cov hlau xeb acid thiab cov tshuaj tiv thaiv nrog cov khoom siv alkaline, yog li nws muaj ntau yam kev siv, thiab nws tus nqi lag luam siab dua li acid me ntsis. Ib hom neutral tshwj xeeb hauv kev lag luam yog cov khoom siv silicone sealant, vim nws siv ncaj qha rau hauv cov hlau phab ntsa thiab iav qauv lossis kev sib dhos tsis yog cov qauv, yog li qhov zoo thiab qib khoom yog qhov siab tshaj plaws hauv cov kua nplaum iav, nws tus nqi lag luam kuj yog qhov siab tshaj plaws.
