Ke polasetiki e sa tšoaroeng

Liphutheloana tse pakiloeng ke mofuta oa thepa ea polymer, li ka mamella ho roala nako e telele le lisebelisoa tsa bohlokoa tse hlokang ho mamella tšabo e phahameng ea litopo le likhohlano tse phahameng.

Hajoale o motle ka ho fetisisa ho hanyetsa kapa boenjiniere bo khethehileng ba prange pai pai pai pai pai pai pai pai. Ts'ebetso ea bobeli, ho na le tšebetso e sa rarolloang

Lits'oants'o tse ngata haholo ke letoto la boenjiniere pa66 le pom nylon le pom ha li sebelisetsoa ho tsoaloa E 'ngoe e khahlanong le ho feta. Leha ho le joalo, ho tsoa tiiso ea mocheso oa nylon ea tšebeliso ea lihlahisoa tsa nylon ho ntlafatsa mohlala oa lihlahisoa tse kholo ho na le mefuta e mengata moo. Re hlophisa lihlahisoa tsa ho khetha lisebelisoa tse tsoang maemong a nnete a ts'ebetso ea ts'ebetso ea tlhokomeliso: Tsamaiso, mojaro, tikoloho, tikoloho, bophelo le ho fumana lenaneo le nepahetseng la thepa. Khetho e ikhethileng ea nylon kapa pom e bua esale pele ka litlhahiso tse setiro tsa fektheri, e le hore sehlahisoa se na le melemo e mengata ea litšenyehelo le litšenyehelo tsa litšenyehelo.

Tekanyetso ea Nylon ka ho eketsa mokhoa o loanngoeng ka mokhoa o sa sebetseng hantle, o eketsang mofuta oa li-molybdenude tse matla tse tsejoang e le "morena oa li-lallic tse phahameng, u ame ka a Boikutlo ba ho thella, sehlahisoa se na le ho se lahlang, melemo ea ho se tsebe ho loketse mosebetsi o phahameng le khatello e phahameng haholo.

Boitsebiso bona bo khetholloa ke ho hanyetsa ho acids, alkalis le li-solvents, 'me bo batla bo sa kopanele li-solvents tsohle. Ka nako e ts'oanang, PTF e tšoauoa ka khatello ea mocheso e phahameng hape e na le monko o tlase haholo oa likhohlano.

Polasetiki e hanyetsanang ka ho fetisisa

Pai polasetiki ke ea lipolanete tse phahameng tsa ts'ebetso, ka matla a mocheso le matla a mocheso le tsietsi ea lik'hemile ke ho se senyehe. Ka likhohlano tse phahameng, mojaro o phahameng le tikoloho e phahameng ea mocheso, ha e se e le ntho e 'ngoe ea polasetiki e thibelang batho ba rorisang.

Melemo le likotsi tsa polasetiki ea pai

1. Melemo: matla a maholo a mangata, ho hanyetsa kame e matla ea lik'hemik'hale, ho bopa hantle.

Litsietsi: theko e phahameng, brittle e fokotsehile.

Libaka tsa kopo ea pai

Paistics e sebelisoa haholo ka aerospace, lienjini tsa liviative, lisebelisoa tsa bongaka, lisebelisoa le likarolo tse ling tse hlokang ho mamella tšabo e phahameng le matla a mangata.

Pai polasetiki ke thepa ea polasetiki e hanyetsanang le 'marakeng kajeno, ho hatelloa ke mocheso haholo, ho hatelloa hantle, ho bopa, ho bopa, ho bopa. e fetoha habonolo. E sebelisoa haholo Aerospace, Koloiti, lisebelisoa tsa motlakase, Lisebelisoa tse ling tse hlokang ho mamella likotsi tse phahameng le likarolo tse matla.
