Polyethylene yog cov thermoplastic siv dav tshaj plaws hauv ntiaj teb los ntawm ntim.Peb tsim peb hom polyethylene, uas yog HDPE, LDPE thiab LLDPE qhov twg:
a) HDPE cov khoom yog tus cwj pwm los ntawm kev sib zog ntau dua thiab kev ua haujlwm zoo dua qub, ua ke nrog cov kev pabcuam kub siab dua.
b) LDPE cov khoom yog ib qho yooj yim rau txheej txheem thiab muaj zog zoo thiab meej.
c) LLDPE cov khoom muaj kev txhim kho lub zog, tshuaj tiv thaiv thiab lub melting point ntau dua, ua rau lawv haum rau cov ntaub ntawv muaj zog zaj duab xis.
| Khoom | Kev siv thawj zaug |
| HDPE | HDPE yog siv los tsim cov khoom noj khoom haus, cov khoom lag luam thiab cov thoob khib nyiab, cov thawv ntim khoom noj rau cov khoom noj xws li cov khoom qab zib khov thiab margarine, lub kaus mom thiab kaw, cov hnab ntim khoom noj thiab cov thawv ntim khoom noj, cov khob haus dej haus, cov khoom noj siv mis, cov tais cij, cov hnab, cov khoom siv kev nyab xeeb xws li raws li lub kaus mom tawv, lub tsev qhwv rau rwb thaiv tsev, lub raj mis rau tsev neeg thiab cov khoom siv tshuaj, lub raj mis mis, kua txiv fwj, thiab cov tank loj rau khaws cov kua dej xws li cov tshuaj ua liaj ua teb thiab cov nyom nyom. |
| LDPE | LDPE yog siv los tsim cov hnab ntim khoom noj, lub raj mis yas rau ntim cov khoom noj thiab cov khoom tu tus kheej, lub hnab ntxuav kom qhuav, hnab ntim dej khov, pallet shrink qhwv, hnab hnyav rau mulch thiab potting av, boil-hauv-bag hnab, coatings ntawm saj zawg zog ntim cov khoom, thiab cov txheej txheem ntawm cov ntawv sau xws li cov thawv ntim mis. |
| LLDPE | LLDPE yog siv los tsim cov khib nyiab thiab nyom-nplooj, cov khoom siv hauv tsev, cov khoom siv hauv tsev, hau rau cov kaus poom kas fes thiab margarine tubs, tais diav, cov thawv ntim khoom hauv tsev, cov thawv khib nyiab hauv tsev, cov khoom ua si loj xws li cov khoom ua si sab nraum zoov, drip irrigation tubing, tiv thaiv txheej rau cov xov tooj xov tooj thiab zaj duab xis, shrink qhwv rau ntau lub ntim cov kaus poom zaub mov, hnab ntim hauv lub thawv, tsim cov hnab thiab pallet stretch qhwv. |
