Kodi silicone sealant ndi chiyani? Kodi kusiyana pakati pa neutral acid silicone sealant ndi kotani?

Silicone sealant ndi phala lopangidwa ndi polydimethylsiloxane ngati chinthu chachikulu chopangira zinthu, chowonjezeredwa ndi crosslinking agent, filler, plasticizer, coupling agent, ndi catalyst mu vacuum state. Limadutsa kutentha kwa chipinda. Limachita ndi madzi mumlengalenga ndipo limauma kuti likhale rabara la silicone lolimba.

2. Kusiyana kwakukulu pakati pa silicone sealant ndi zina zomatira zachilengedwe?

Ili ndi mphamvu yolimba, mphamvu yolimba kwambiri, kukana nyengo, kukana kugwedezeka, kukana chinyezi, kukana fungo, komanso kusinthasintha kwakukulu kuzizira ndi kutentha. Kuphatikiza ndi kugwiritsidwa ntchito kwake kwakukulu, imatha kuzindikira kulimba pakati pa zipangizo zambiri zomangira, komwe ndi khalidwe lapadera la silicone sealant lomwe ndi losiyana ndi zipangizo zina zomatira zachilengedwe. Izi zimachitika chifukwa cha kapangidwe kapadera ka molekyulu ya silicone sealant. Unyolo waukulu wa Si—O bond suwonongeka mosavuta ndi kuwala kwa ultraviolet. Nthawi yomweyo, kutentha kwa galasi kwa rabara ya silicone kumakhala kotsika kwambiri kuposa kwa zipangizo wamba zachilengedwe. Imathabe kukhalabe yolimba bwino pansi pa kutentha kochepa (-50°C) popanda kusweka kapena kusweka, ndipo sikophweka kufewa ndikuwonongeka pansi pa kutentha kwakukulu (200°C). Imatha kukhalabe ndi magwiridwe antchito okhazikika pa kutentha kwakukulu. Silicone sealant simayendanso chifukwa cha kulemera kwake, kotero ingagwiritsidwe ntchito m'malo olumikizirana pamwamba kapena m'mbali popanda kugwa, kugwa kapena kuthawa. Makhalidwe abwino kwambiri a silicone sealants ndi chifukwa chofunikira kwambiri chogwiritsidwa ntchito kwambiri pantchito yomanga, ndipo izi ndi zabwino kuposa zina zotsekera zachilengedwe.
