I-Sealant: Isixhobo esiPhambili kuShishino lwangoku kunye noLwakhiwo

I-Sealant sisixhobo se-polymer esineempawu ezibalaseleyo zokudibanisa kunye nokutywina, ezisetyenziswa ngokubanzi kulwakhiwo, iimoto, i-elektroniki, i-aerospace, kunye namanye amasimi. Umsebenzi wayo ophambili kukugcwalisa izikhewu, ukuthintela ukuvuza kwamanzi okanye igesi, kunye nokukhusela kwizinto ezisingqongileyo ezifana namanzi, imisebe ye-UV, ukuguquguquka kweqondo lokushisa, kunye nokubola kweekhemikhali.

 

Ngokusekwe ekubunjweni kwazo, izitywini zolu phawu zihlelwa ngokuyintloko njenge-silicone sealants, ii-polyurethane sealants, ii-polysulfide sealants, kunye ne-acrylic sealants. I-silicone sealants, ngenxa yokuchasana ngokugqwesileyo kumaqondo aphezulu kunye namaqondo aphantsi (-50℃ukuya kwi-200 degree), ukumelana nemozulu, kunye no-elasticity, yinto ekhethiweyo yokutywina izindonga zamakhethini, iingcango kunye neefestile. Ii-polyurethane sealants, ngenxa yokomelela kwazo okuphezulu, ukuxhathisa okugqwesileyo kwe-abrasion, kunye neempawu zokubopha, ziqhele ukusetyenziswa kwimveliso yeemoto kunye nokutywinwa kwezixhobo zemizi-mveliso. Ii-Polysulfide sealants zigqwesa kwiiprojekthi zokuthintela amanzi, ngakumbi kwiindawo eziphantsi kokuntywiliselwa ixesha elide emanzini.

Kwicandelo lokwakha, ii-sealants zisetyenziselwa ukudibanisa udonga lwamakhethini, ukufakwa kweefestile, i-flooring, kunye nezinye izicelo zokuqinisekisa ukungena komoya kunye nokungangeni kwamanzi kwezakhiwo ngelixa uphucula i-aesthetics yesakhiwo. Kwishishini leemoto, iisealants zisetyenziselwa ukutywina ii-windshields, izibane zentloko, amagumbi enjini, kunye nezinye iindawo, ukuqinisekisa ukhuseleko lokuqhuba. Ishishini le-elektroniki lixhomekeke kwii-sealants ukukhusela izinto ezibuthathaka kumswakama kunye nothuli, ukwandisa ubomi bezixhobo.

Ngokukhula kolwazi lwendalo esingqongileyo,{0}}izitywini ze-VOC ezisezantsi kunye nezitywini eziguquguqukayo zebhayoloji ziba ziindawo zophando nophuhliso. Kwixesha elizayo, ukuqhubela phambili kwisayensi yezixhobo kuya kuqhuba izinto zokutywina ukuya ekusebenzeni okuphezulu, ukusebenzelana kakuhle kwendalo, kunye nobukrelekrele obuninzi bokuhlangabezana neemfuno ezingqongqo zamashishini ahlukeneyo.

Ngelixa zibonakala zingabalulekanga, izitywini ziyinto eyimfuneko kwaye ibalulekile kushishino lwangoku kunye nolwakhiwo, kwaye ukuqhubela phambili kwethekhinoloji kuya kuqhubeka ukuqhubela phambili uphuhliso kwiinkalo ezinxulumeneyo.
