Kopo
Polypropylene e sebelisoa haholo tlhahisong ea liaparo, likobo le lihlahisoa tse ling tsa faeba, lisebelisoa tsa bongaka, likoloi, libaesekele, likarolo, liphaephe tsa lipalangoang, lijana tsa lik'hemik'hale, jj., 'me e boetse e sebelisoa liphuthelong tsa lijo le meriana.
TAELO
Polypropylene, e khutsufalitsoeng e le PP, ke ntho e tiileng e se nang 'mala, e se nang monko, e se nang chefo, e bonaletsang.
(1) Polypropylene ke resine ea maiketsetso ea thermoplastic e nang le ts'ebetso e ntle haholo, e leng polasetiki e se nang 'mala le e bonaletsang ea thermoplastic e bobebe ea morero o akaretsang. E na le k'hemik'hale e hanyetsang, e hanyetsa mocheso, e thibelang motlakase, e na le thepa ea mechini e matla le thepa e ntle ea ts'ebetso e hanelang ho tsofala, jj., e leng se etsang hore polypropylene e sebelisoe ka potlako mechining, likoloing, lisebelisoa tsa elektroniki, kaho, masela, liphuthelong ho tloha ha e thehoa. E 'nile ea ntlafatsoa haholo' me ea sebelisoa masimong a mangata a kang temo, meru, litlhapi le indasteri ea lijo.
(2) Ka lebaka la ho ba polasetiki ha eona, thepa ea polypropylene e ntse e nkela lihlahisoa tsa lehong sebaka butle-butle, 'me matla a phahameng, ho tiea le ho hanyetsa ho tsofala ho phahameng butle-butle li nkile sebaka sa mesebetsi ea mechini ea litšepe. Ho phaella moo, polypropylene e na le mesebetsi e metle ea ho kopanya le ho kopanya, 'me e na le sebaka se seholo sa ts'ebeliso konkreite, masela, liphutheloana le temo, meru le ho tšoasa litlhapi.
THEPA
Polypropylene e na le likarolo tse ngata tse ntle:
1. Bongata ba dibopeho bo bonyenyane, ke 0.89-0.91 feela, e leng e 'ngoe ea mefuta e bobebe ka ho fetisisa ea polasetiki.
2. Litšobotsi tse ntle tsa mechini, ntle le ho hanyetsa tšusumetso, litšobotsi tse ling tsa mechini li molemo ho feta polyethylene, ts'ebetso e ntle ea ho bopa.
3. Ka ho hanyetsa mocheso o phahameng, mocheso o tsoelang pele oa tšebeliso o ka fihla ho 110-120℃.
4. Thepa e ntle ea lik'hemik'hale, hoo e batlang e se na monyollo oa metsi, ha e na karabelo ho lik'hemik'hale tse ngata.
5. Sebopeho se hloekileng, ha se na chefo.
6. Ho thibela motlakase hantle.
7. Ponaletso ea lihlahisoa tsa polypropylene e betere ho feta ea lihlahisoa tsa polyethylene tse nang le bongata bo phahameng.
HO PHAKELA LE HO POLOKA
50/moropa, 25kg/moropa kapa e etselitsoe ho latela dikopo tsa moreki.
Ho phaella ho sena, dihlahiswa tsa rona tse tsebahalang keho rota ha fiberglass, meseme ea fiberglassleboka ba ho lokolla hlobo.Romela imeile haeba ho hlokahala.
