Lisebelisoa tsa lihlahisoa tsa polasetiki ke life?
Lihlahisoa tsa polasetiki li arotsoe haholo ka mefuta e 'meli ea thermoplastic le thermosetting, tse latelang ke kenyelletso e qaqileng, ke tšepa ho thusa.
1. Thermoplastic
Thermoplastics, eo hape e tsejoang e le li-resin tsa thermoplastic, ke sehlopha se seholo sa polasetiki.Li entsoe ka thepa ea maiketsetso ea polymer e ka phallang ho e mong ka ho qhibiliha ka mocheso 'me e khona ho phekola hape.Lisebelisoa tsena hangata li na le boima bo phahameng ba limolek'hule 'me li na le sebopeho sa ketane ea limolek'hule tse pheta-phetoang.Thermoplastics e ka sebetsoa ka ho bōptjoa ka ente, extrusion, ho bōptjoa ha molumo, calendering le mekhoa e meng ho etsa likarolo le lihlahisoa tsa libopeho le boholo bo fapaneng.
(1) Polyethylene (PE) : PE ke e 'ngoe ea li-plastiki tse tloaelehileng ka ho fetisisa, tse sebelisoang haholo ho paka, liphaephe, li-insulators tsa terata le merero e meng.Ho ea ka sebopeho sa limolek'hule le boima ba eona, PE e ka aroloa ka polyethylene e phahameng (HDPE), polyethylene e tlaase (LDPE) le polyethylene e tlaase e tlaase (LLDPE).
Polypropylene (PP) : PP hape ke polasetiki e tloaelehileng, e sebelisoang hangata ka lijaneng, libotlolong le lisebelisoa tsa bongaka.PP ke polasetiki ea semi-crystalline, kahoo e thata ebile e pepenene ho feta PE.
3PVC e ka ba mebala ebile e hanana le lik'hemik'hale tse ngata.
(4) Polystyrene (PS) : PS e atisa ho sebelisoa ho etsa lisebelisoa tsa ho paka tse bobebe, tse bonaletsang, tse kang lijana tsa lijo le mabokose a polokelo.PS e boetse e sebelisoa haholo ho etsa foam, joalo ka EPS foam.
Acrylonitrile-butadiene-styrene copolymer (ABS) : ABS ke polasetiki e thata, e hananang le tšusumetso eo hangata e sebelisetsoang ho etsa matshwaro a lisebelisoa, matlo a motlakase le likarolo tsa likoloi.
(6) Tse ling: Ho phaella moo, ho na le mefuta e meng e mengata ea thermoplastics, e kang polyamide (PA), polycarbonate (PC), polyformaldehyde (POM), polytetrafluoroethylene (PTFE) joalo-joalo.
2, polasetiki ea thermosetting
Li-plastiki tsa thermosetting ke sehlopha se khethehileng sa polasetiki, se fapaneng le thermoplastics.Lisebelisoa tsena ha li nolofatse le ho phalla ha li futhumala, empa li phekoloa ke mocheso.Li-plastiki tsa thermosetting hangata li na le matla a holimo le ho thatafala 'me li loketse lisebelisoa tse hlokang ho tšoarella le matla a mangata.
Epoxy resin (EP) : Epoxy resin ke polasetiki e thata ea thermosetting e sebelisoang haholo indastering ea kaho, ea elektroniki le ea likoloi.Li-resin tsa epoxy li ka sebetsana le lik'hemik'hale ka lisebelisoa tse ling ho etsa li-adhesives tse matla le liphahlo.
(2) Polyimide (PI) : Polyimide ke polasetiki e thibelang mocheso haholo e ka bolokang thepa ea eona ka mocheso o phahameng.E sebelisoa haholo indastering ea lifofane, lisebelisoa tsa elektroniki le tsa likoloi ho etsa lisebelisoa le liphahlo tse hanyetsanang le mocheso o phahameng.
(3) Tse ling: Ho phaella moo, ho na le mefuta e meng e mengata ea lipolasetiki tsa thermosetting, tse kang phenolic resin, furan resin, polyester unsaturated joalo-joalo.
