Iindaba

Ngaba ujonge ukuphucula umgca wakho wokupakisha okanye ukuphucula ukusebenza kwezakhiwo ezine-laminate? Esi sikhokelo sisebenzayo sihlola imigaqo ebalulekileyo, ukukhethwa kwezinto, amanyathelo okucubungula, kunye neendlela zokusombulula iingxaki kwi-extrusion coating (ekwaziwa ngokuba yi-lamination) - itekhnoloji esetyenziswa kakhulu kumacandelo okupakisha, ezonyango, ezithuthi, kunye namashishini.

Yintoni iLamination (i-Extrusion Coating) kwaye isebenza njani?

I-Lamination, okanye i-extrusion coating, yinkqubo ebandakanya ukugquma iplastiki enyibilikisiweyo (edla ngokuba yi-polyethylene, i-PE) ngokulinganayo kwiindawo ezifana nephepha, ilaphu, izinto ezingalukwanga, okanye i-aluminium foil. Kusetyenziswa isixhobo sokukhupha, iplastiki iyanyibilikiswa, igqunywe, ize ipholiswe ukuze kwenziwe isakhiwo esidibeneyo.

Umgaqo oyintloko kukusebenzisa ukunyibilika kweplastiki enyibilikisiweyo kumaqondo obushushu aphezulu ukuze kufezekiswe ukubophana okuqinileyo ne-substrate, ngaloo ndlela kongezwa iipropati zokuthintela, ukuvaleka kobushushu, kunye nokuqina kwezinto ezisisiseko.

Amanyathelo eNkqubo yokuLamination ephambili

1. Ukulungiswa kwezinto eziluhlaza: Khetha iipellets zeplastiki ezifanelekileyo (umz., i-PE, i-PP, i-PLA) kunye nee-substrates (umz., iphepha eliyi-virgin, ilaphu elingalukwanga).

2. Ukunyibilika nokuKhutshwa kwePlastiki: Iipellets zeplastiki zifakwa kwi-extruder, apho zinyibilikiswa khona zibe lulwelo oluqinileyo kubushushu obuphezulu. Iplastiki enyibilikisiweyo emva koko ikhutshwa nge-T-die ukuze yenze ukunyibilika okufana nefilimu.

3. Ukwaleka kunye nokudibanisa: Ifilimu yeplastiki enyibilikisiweyo igqunywe ngokuchanekileyo phezu komphezulu we-substrate engakavulwa phantsi kolawulo loxinzelelo. Kwindawo yokugquma, iplastiki enyibilikisiweyo kunye ne-substrate zidityaniswe ngokuqinileyo phantsi kwesenzo se-pressure rollers.

4. Ukupholisa kunye nokuseta: Izinto ezidityanisiweyo zidlula ngokukhawuleza kwiirola zokupholisa, zivumela umaleko weplastiki onyibilikisiweyo ukuba uphole ngokukhawuleza kwaye uqine, wenze ifilimu yeplastiki eqinileyo.

5. Ukujika: Izinto ezidityanisiweyo ezipholileyo nezibekwe nge-laminate zifakwa kwimiqolo ukuze zicutshungulwe kwaye zisetyenziswe kamva.

6. Amanyathelo Okuzikhethela: Kwezinye iimeko, ukuphucula ukunamathela komaleko ofakwe ilaminate okanye ukuphucula iimpawu zomphezulu, i-substrate inokunyangelwa i-corona ngaphambi kokuba igqunywe.
