Likarolo le mefuta ea thermoplastic polymer

Thermoplastic polymer ke mofuta oa polymer e khetholloang ka bokhoni ba eona ba ho qhibiliha ebe e tiisa r.epentle le phetoho e kholo ea thepa ea eona ea lik'hemik'hale kapa litšobotsi tsa ts'ebetso. Thermoplastic polymers li sebelisoa haholo lits'ebetsong tse fapaneng, ho kenyelletsa ho paka, likarolo tsa likoloi, lisebelisoa tsa motlakase le lisebelisoa tsa bongaka, hara 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:

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
