Sealant: Ntho ea Bohlokoa indastering ea Sejoale-joale le Kaho

Sealant ke thepa ea polymer e nang le thepa e ntle ea ho kopanya le ho tiisa, e sebelisoang haholo kahong, likoloi, lisebelisoa tsa elektroniki, sefofane le masimo a mang. Mosebetsi oa eona oa mantlha ke ho tlatsa likheo, ho thibela ho lutla ha metsi kapa khase, le ho sireletsa khahlano le maemo a tikoloho joalo ka metsi, mahlaseli a UV, ho fetoha ha mocheso le ho bola ha lik'hemik'hale.

 

Ho ipapisitsoe le sebopeho sa bona, li-sealants li arotsoe haholo e le li-silicone sealants, polyurethane sealants, polysulfide sealants, le acrylic sealants. Li-silicone sealants, ka lebaka la ho hanyetsa ha tsona mocheso o phahameng le o tlaase (-50℃ho 200 degree), ho hanyetsa boemo ba leholimo, le elasticity, ke lisebelisoa tse ratoang bakeng sa ho tiisa marako a likharetene tsa mohaho, mamati le lifensetere. Li-sealants tsa polyurethane, ka lebaka la matla a tsona a phahameng, khanyetso e ntle ea abrasion, le thepa ea tlamahano, li sebelisoa hangata ho etsa likoloi le ho tiisa lisebelisoa tsa indasteri. Li-sealants tsa Polysulfide li sebetsa hantle haholo mererong ea ho thibela metsi, haholo-holo libakeng tse tlas'a ho qoelisoa nako e telele ka metsing.

Lefapheng la kaho, li-sealants li sebelisoa ho kopanya marako a likharetene, ho kenya lifensetere, fatše, le lits'ebetso tse ling ho netefatsa ho thibela moea le ho thibela metsi ha mehaho e ntse e ntlafatsa botle ba mohaho. Indastering ea likoloi, li-sealants li sebelisoa ho tiisa lifensetere tsa moea, mabone a pele, liphaposi tsa enjene le libaka tse ling, ho netefatsa polokeho ea likoloi. Indasteri ea lisebelisoa tsa elektroniki e itšetleha ka li-sealant ho sireletsa likarolo tse bobebe ho tsoa mongobo le lerōleng, e lelefatsa bophelo ba lisebelisoa.

Ka tlhokomeliso e ntseng e hola ea tikoloho, li-sealant tse tlase-VOC le li-sealant tse senyehang habonolo li fetoha libaka tsa lipatlisiso le nts'etsopele. Nakong e tlang, tsoelo-pele ea mahlale a thepa e tla etsa hore li-sealants li be le ts'ebetso e phahameng, botsoalle bo matla ba tikoloho, le bohlale bo boholo ho fihlela litlhoko tse ntseng li eketseha tsa liindasteri tse fapaneng.

Leha e bonahala e se letho, li-sealant ke ntho ea bohlokoahali ebile e bohlokoa indastering ea sejoale-joale le kaho, 'me tsoelopele ea theknoloji e tla tsoelapele ho tsamaisa nts'etsopele mafapheng a amanang.
