Lamination (Extrusion Coating) ke Eng, 'me e sebetsa Joang?

Lamination, kapa extrusion coating, ke mokhoa o kenyelletsang ho roala polasetiki e qhibilihisitsoeng (haholo-holo polyethylene, PE) ka mokhoa o ts'oanang holim'a likaroloana tse kang pampiri, lesela, tse sa lohiloeng, kapa foil ea aluminium. Ho sebelisa sesebelisoa sa extrusion, polasetiki ea qhibiliha, e koahetsoe, 'me e pholile ho etsa sebopeho se nang le likarolo tse ngata.

Molao-motheo oa mantlha ke ho sebelisa mokelikeli oa polasetiki e qhibilihisitsoeng mochesong o phahameng ho fihlela tlamahano e tiileng le substrate, ka hona ho eketsa thepa ea litšitiso, ho tiisa mocheso, le ho tšoarella ho thepa ea motheo.

Mehato ea Bohlokoa ea Ts'ebetso ea Lamination

1. Tokiso ea Lintho tse tala: Khetha li-pellets tsa polasetiki tse loketseng (mohlala, PE, PP, PLA) le li-substrates (mohlala, pampiri e sa tsoakoang, lesela le sa lohiloeng).

2. Ho qhibiliha ha Plastiki le Extrusion: Li-pellets tsa polasetiki li kenngoa ka har'a extruder, moo li qhibilihang ka har'a mokelikeli oa viscous ka mocheso o phahameng. Joale polasetiki e qhibilihisitsoeng e tšeloa ka T-die ho etsa mokelikeli o tšoanang oa filimi.

3. Ho Koaela le ho Kopanya: Filimi ea polasetiki e entsoeng ka ho qhibilihisoa e koahetsoe hantle ka holim'a karoloana ea pele ho maqeba tlas'a taolo ea tsitsipano. Sebakeng sa ho roala, polasetiki e qhibilihisitsoeng le substrate li kopantsoe ka thata tlas'a ketso ea li-roller tsa khatello.

4. Cooling le Setting: Thepa e kopantsoeng ka potlako e feta ka li-roller tse pholileng, e lumellang lesela la polasetiki le qhibilihisitsoeng hore le pholile ka potlako le ho tiisa, le etsa filimi e matla ea polasetiki.

5. Maqhubu: Thepa e pholisitsoeng le e behiloeng ea laminated composite e etsoa meqolo bakeng sa ho sebetsa le ho sebelisoa.

6. Mehato ea Boikhethelo: Maemong a mang, ho ntlafatsa ho khomarela lera la laminated kapa ho ntlafatsa thepa ea holim'a metsi, substrate e ka 'na ea fumana phekolo ea corona pele e roaloa.

• Polypropylene (PP)

Ho hanyetsa mocheso ho betere le ho tiea ho feta PE. E loketse lits'ebetso tsa ho koala mocheso o phahameng.

• Lipolasetiki tse ka senyehang

PLA: E pepenene, e ka senyeha, empa e lekanyelitsoe ho hanyetsa mocheso.

PBS/PBAT: E feto-fetoha le maemo; e loketseng bakeng sa tharollo ea moshoelella ea ho paka.

• Li-Polymers tse khethehileng

EVOH: Tšireletso e ntle ea oksijene, e atisang ho sebelisoa e le lera le bohareng ba ho paka lijo.

Li-Ionomers: Ho hlaka ho hoholo, ho hanyetsa oli, ho tiiseha ho hoholo.
