Iindaba

Ngaba ujonge ukwandisa umgca wakho wokupakisha okanye uphucule ukusebenza kwezakhiwo ze-laminated? Esi sikhokelo esisebenzayo siphonononga imigaqo ebalulekileyo, ukhetho lwezinto eziphathekayo, amanyathelo okucubungula, kunye neendlela zokusombulula ingxaki kwi-extrusion coating (eyaziwa ngokuba yi-lamination) - iteknoloji esetyenziswa ngokubanzi kumacandelo okupakisha, ezonyango, eemoto kunye namashishini.

Yintoni iLamination (Extrusion Coating) kwaye Isebenza Njani?

I-Lamination, okanye i-extrusion coating, yinkqubo ebandakanya ukugquma iplastiki etyhidiweyo (ixhaphake i-polyethylene, i-PE) ngokufanayo kwi-substrates efana nephepha, ilaphu, i-non-wovens, okanye i-aluminium foil. Ukusebenzisa i-extrusion device, iplastiki iyancibilika, igqunywe, kwaye ipholile ukwenza isakhiwo esidibeneyo.

Umgaqo ongundoqo kukusebenzisa i-fluidity yeplastiki etyhidiweyo kumaqondo aphezulu obushushu ukufezekisa ukudibanisa okuqinileyo kunye ne-substrate, ngoko ke ukongeza iipropati zomqobo, ukutywinwa kobushushu, kunye nokuqina kwizinto ezisisiseko.

Amanyathelo eNkqubo yokuLamination aPhambili

1. ULungiselelo lweMathiriyeli ekrwada: Khetha iipeliti zeplastiki ezifanelekileyo (umzekelo, i-PE, i-PP, i-PLA) kunye ne-substrates (umz., iphepha elingenangqondo, ilaphu elingalukwanga).

2. Ukunyibilika kwePlastiki kunye ne-Extrusion: Iipilisi zeplastiki zondliwa kwi-extruder, apho zincibilika kwi-viscous fluid kumaqondo aphezulu. Iplastiki etyhidiweyo iye yakhutshelwa kwi-T-die ukuze yenze ifilimu efana nefilimu enyibilikayo.

3. Ukwambathisa kunye noKudibanisa: Ifilim yeplastiki enyibilikisiweyo igqunywe ngokuchanekileyo kumphezulu we-substrate yangaphambi kokungenamanxeba phantsi kolawulo loxinzelelo. Kwindawo yokugqoka, iplastiki etyhidiweyo kunye ne-substrate ihlanganiswe ngokuqinileyo kunye phantsi kwesenzo soxinzelelo lwe-rollers.

4. Ukupholisa kunye nokuSeta: Izinto ezixutywe ngokukhawuleza zidlula kwii-roller zokupholisa, ezivumela ukuba iplastiki etyhidiweyo iphole ngokukhawuleza kwaye iqiniswe, yenze ifilimu yeplastiki enamandla.

5. Ukujija: Isixhobo esipholileyo nesisetiweyo esidityanisiweyo sidityaniswe sibe yimiqulu ukuze siqhubeke nokusetyenziswa.

6. Amanyathelo okuzikhethela: Kwezinye iimeko, ukuphucula ukunamathela komgangatho owenziwe nge-laminated okanye ukunyusa iipropati ezingaphezulu, i-substrate inokuthi iqhube unyango lwe-corona ngaphambi kokugquma.

ISikhokelo sokuKhetha i-Substrate kunye nePlastiki ye-Extrusion Coating okanye iLamination
