Likarolo le mefuta ea thermoplastic polymer
Polymer ea thermoplastic ke mofuta oa polymer o khetholloang ka bokhoni ba oona ba ho qhibilihisoa ebe o tiea khafetsa ntle le phetoho e kholo litšobotsing tsa eona tsa lik'hemik'hale kapa litšobotsi tsa ts'ebetso. Polymer ea thermoplastic e sebelisoa haholo lits'ebetsong tse fapaneng, ho kenyeletsoa liphutheloana, likarolo tsa likoloi, likarolo tsa motlakase le lisebelisoa tsa bongaka, har'a tse ling.
Li-polymers tsa thermoplastic li khetholloa ho tsoa mefuteng e meng ea li-polymers, joalo ka li-polymers tsa thermosetting le li-elastomer, ka bokhoni ba tsona ba ho qhibiliha le ho fetoloa hangata. Sena se bakoa ke taba ea hore li-polymers tsa thermoplastic li entsoe ka liketane tse telele tsa limolek'hule tse kopantsoeng hammoho ke matla a fokolang a li-intermolecular. Ha mocheso o sebelisoa ho polymer ea thermoplastic, matla ana a intermolecular a fokotseha, a lumella liketane hore li tsamaee ka bolokolohi 'me thepa e be bonolo haholoanyane.
E 'ngoe ea melemo ea bohlokoa ea li-polymer tsa thermoplastic ke ho feto-fetoha ha tsona. Li ka etsoa hore li be le mefuta e mengata e fapaneng ea 'mele le ea mochini, ho kenyelletsa ho tenyetseha, ho tiea, matla, le ho hanyetsa mocheso, lik'hemik'hale le mahlaseli a UV. Sena se etsa hore li tšoanelehe bakeng sa lits'ebetso tse fapaneng tse hlokang litšobotsi tse ikhethang tsa ts'ebetso.
Molemo o mong oa li-polymer tsa thermoplastic ke boiketlo ba tsona ba ho sebetsa. Hobane li ka qhibilihisoa le ho nchafatsoa ka makhetlo a mangata, li ka bōptjoa habonolo ho ba libopeho tse rarahaneng ho sebelisa mekhoa e fapaneng, e kang ente ea ente, extrusion, blow molding, le thermoforming. Sena se etsa hore e be khetho e theko e tlaase bakeng sa tlhahiso e kholo ea likarolo le likarolo.
Ho na le mefuta e mengata e fapaneng ea li-polymer tsa thermoplastic, e 'ngoe le e' ngoe e na le thepa ea eona e ikhethang le lits'ebetso. E meng ea mefuta e tsebahalang haholo e kenyelletsa:
- nhua polyethylene (PE): Polymer ea thermoplastic e sebelisoang haholo e tsebahalang ka theko e tlase, ho tenyetseha, le ho hanyetsa tšusumetso le lik'hemik'hale. E sebelisoa lits'ebetsong tse fapaneng, ho kenyelletsa ho paka, liphaephe, le terata.
- Polypropylene (PP): Polymer e 'ngoe e sebelisoang haholo ea thermoplastic e tsejoang ka ho satalla, ho tiea, le ho hanyetsa mocheso le lik'hemik'hale. E sebelisoa lits'ebetsong tse fapaneng, ho kenyelletsa likarolo tsa koloi, liphutheloana le lisebelisoa tsa bongaka.
- Polyvinyl chloride (PVC): Polymer ea thermoplastic e tsebahalang ka ho ikamahanya le maemo, ho tšoarella nako e telele, le ho hanyetsa mollo le lik'hemik'hale. E sebelisoa mefuteng e fapaneng ea ts'ebetso, ho kenyelletsa liphaephe, terata, le fatše.
- Polystyrene (PS): Polima ea thermoplastic e tsebahalang ka ho hlaka, ho tiea, le theko e tlase. E sebelisoa lits'ebetsong tse fapaneng, ho kenyelletsa ho paka, likopi tse lahloang, le ho kenya letsoho.
- Acrylonitrile-butadiene-styrene (ABS): Polymer ea thermoplastic e tsebahalang ka matla a eona, ho tiea, le ho hanyetsa mocheso le tšusumetso. E sebelisoa lits'ebetsong tse fapaneng, ho kenyelletsa likarolo tsa koloi, lintho tsa ho bapala le lisebelisoa tsa elektroniki.
Ntle le li-polymer tsena tse tloaelehileng tsa thermoplastic, ho na le mefuta e meng e mengata e fumanehang, e 'ngoe le e' ngoe e na le thepa ea eona e ikhethang le lits'ebetso. Mehlala e meng e kenyelletsa polycarbonate (PC), polyamide (PA), polyethylene terephthalate (PET), le fluoropolymers joalo ka polytetrafluoroethylene (PTFE).
Ka kakaretso, li-polymer tsa thermoplastic ke khetho e feto-fetohang le e theko e tlase bakeng sa lits'ebetso tse fapaneng. Bokhoni ba bona ba ho qhibiliha le ho fetoloa ka makhetlo a mangata, ho kopantsoe le mefuta e mengata ea 'mele le ea mechine, ho etsa hore e be thepa ea bohlokoa liindastering tse ngata.
