1. Kodi silicone sealant ndi chiyani?
Silicone sealant ndi phala lopangidwa ndi polydimethylsiloxane monga zopangira zazikulu, zowonjezeredwa ndi crosslinking agent, filler, plasticizer, coupling agent, and catalyst in vacuum state. Imadutsa kutentha kwapakati. Imakhudzidwa ndi madzi mumlengalenga ndikulimba kupanga mphira yotanuka silikoni.
2. Kusiyana kwakukulu pakati pa silicone sealant ndi zosindikizira zina za organic?
Ili ndi kumatirira kolimba, kulimba kwamphamvu kwambiri, kukana kwanyengo, kukana kugwedezeka, kukana chinyezi, kukana kununkhira, komanso kusinthika kukusintha kwakukulu kwa kuzizira ndi kutentha. Kuphatikizidwa ndi kuthekera kwake kokulirapo, imatha kuzindikira kumamatira pakati pa zida zambiri zomangira, zomwe ndi mawonekedwe apadera a silicone sealant omwe ndi osiyana ndi zida zina zomatira organic. Izi ndichifukwa cha mawonekedwe apadera a molekyulu a silicone sealant. Unyolo waukulu wa Si-O chomangira sichiwonongeka mosavuta ndi cheza cha ultraviolet. Pa nthawi yomweyo, galasi kusintha kutentha kwa silikoni mphira ndi otsika kwambiri kuposa wamba organic zipangizo. Imatha kukhalabe otanuka bwino pansi pa kutentha kochepa (-50 ° C) popanda kugwedeza kapena kusweka, ndipo sikophweka kufewetsa ndi kutsika pansi pa kutentha kwakukulu (200 ° C). Ikhoza kusunga ntchito yokhazikika pa kutentha kwakukulu. Silicone sealant sichimayenda chifukwa cha kulemera kwake, kotero imatha kugwiritsidwa ntchito pamalumikizidwe apamwamba kapena makoma am'mbali popanda sag, kugwa kapena kuthawa. Izi zapamwamba za silicone sealants ndi chifukwa chofunikira chogwiritsira ntchito kwambiri pomanga, ndipo malowa ndiwopindulitsanso kuposa zosindikizira zina.
