Tšebeliso le mehato ea thibelo ea taolo ea foam ea PVC ke efe?

Tšebeliso ea molaoli oa foam oa PVC:

Ho fafatsa ha thepa ea PVC ke ho etsa hore kabo ea limolek'hule ea PVC e tšoane haholoanyane. Etsa hore boleng ba lihlahisoa tsa PVC bo be le sepheo se setle haholoanyane. Leqephe la PVC le foamiloeng ke molaoli oa foam oa PVC le na le sebopeho se setle haholo se ikemetseng. Ka linako tse ling, ha re ntse re sebelisa molaoli oa foam oa PVC, re boetse re sebelisa li-accelerator tse ling tsa foam. Li-accelerator tsa foam li kenyelletsa li-oxide tsa tšepe tse kang zinc oxide le lead oxide, letsoai la asiti ea organic joalo ka zinc stearate, le li-derivatives tsa urea.

Melemo ea molaoli oa foam oa PVC:

Selaoli sa ho fofonela sa PVC se na le litšobotsi tsohle tsa lithuso tsa ho sebetsana le PVC, 'me boima ba limolek'hule bo phahame ho feta ba lithuso tsa ho sebetsana le PVC. Ho eketsa tekanyo e loketseng ea taolo ea ho fofonela ea PVC nakong ea ts'ebetso ea lihlahisoa tsa PVC ho ka ntlafatsa matla a ho qhibiliha le ho thibela fu.ho qhibiliha ha dipululana. Ka nako e ts'oanang, e ka boela ea ba le phello e ntle ea ho etsa polasetiki. Sepheo ke ho netefatsa hore ho qhibiliha ho na le mokelikeli o motle.

Litlhokomelo bakeng sa tšebeliso ea molaoli oa foam oa PVC:

Ha o sebedisa diphetodi tsa foam tsa PVC, ho bohlokwa ho ela hloko dihlahiswa tsa PVC tse nang le maemo a fapaneng a polymerization le ho kgetha diphetodi tse fapaneng tsa foam. Dihlahiswa tsa foam tsa polasetiki di kenyeletsa diboto tsa foam, diboto tse teteaneng tsa foam, diboto tse tshesane tsa foam, diboto tsa foam tsa polasetiki ya lepolanka, diboto tsa foam tsa polasetiki ya loto, jj. Kaha di-additives tsa foam tsa PVC le tsona ke dintho tsa acrylic tse nang le thepa ya thuso ya ho sebetsana le tshebetso, tlhokomelo e lokela ho lefshwa ho leka-lekana ha ho tlotsa ka hare le ka ntle ha ho sebediswa tsona.

Lintlha tsa bohlokoa tsa taolo ea ts'ebetso ea foam ea PVC:

Ho bopa foam ea polasetiki ho arotsoe ka mekhoa e meraro: ho thehoa ha khubu ea bubble, katoloso ea khubu ea bubble, le ho tiea ha 'mele oa foam. Bakeng sa maqephe a foam a PVC a nang le lik'hemik'hale tse eketsang foam, katoloso ea nuclei ea bubble e na le tšusumetso e matla boleng ba leqephe la foam. PVC ke ea limolek'hule tse otlolohileng tsa ketane tse nang le liketane tse khutšoane tsa limolek'hule le matla a tlase a ho qhibiliha. Nakong ea ts'ebetso ea katoloso ea khubu ea bubble ho ba lipululana, ho qhibiliha ha hoa lekana ho koahela lipululana, 'me khase e sekamela ho tlala le ho kopana le lipululana tse kholo, e leng se fokotsang boleng ba sehlahisoa sa maqephe a foam.
