Kunzima ukuphikisa ukuba ukunambitha kwezitya kuxhomekeke kwimimiselo yokugcina yamacandelo ayo. Ngelishwa, ezininzi iimveliso zinexesha elincinci lobomi. Kodwa ezinye izixhobo zinceda ukwandisa. Bangabandakanya ifilimu yokutya yePVC.
Iyintoni ukusetyenziswa kwefilimu yePVC?
I-PVC, okanye ityhila ifilimu, ixutywe, ngokuqhelekileyo ngesimo somqulu, eyenziwe nge-polyvinyl chloride, impahla ye-polymer eneempawu ezikhethekileyo. Okokuqala, ifilimu elula yokutya idlula umoya kwaye ivelise i-carbon dioxide. Ngenxa yobu buchule, iimveliso ezifakwe kuso zibonakala 'ziphefumula', kodwa umoya awufumani ngaphakathi kwiphakheji. Ngenxa yoko phantsi kwe-PVC yokunweba iifilimu azibonakali zihlazo ze-condensate. Ngenxa yoko, i-shelf yobomi bemveliso yanda kakhulu. Ukupakishwa kwifilimu elula kunokuba nemveliso esandululwe. Eyona nto ibalulekileyo kulolu hlobo lwemveliso, njengesonka kunye nemiqulu .
Ukongeza, ifilimu ye-PVC ikhuselekile ngokupheleleyo, ayiyikushiya nayiphi na into eyingozi kwimveliso. Ngokusisiseko, ifilimu ye-PVC isetyenziselwa iimveliso ezahlukeneyo zokutya - intlanzi, inyama, i-sausages, imifuno, ushizi, i-sausages, isonka. Ububanzi befilimu yokutya bubanzi bubanzi: phantse zonke iintambo zokuthengisa kunye neevenkile. Yisebenzise kwaye kwikhaya labesifazane abasebenzayo.
Iindidi zokutya ifilimu ye-PVC
Icandelo eliphambili ekuvelweni kwefilimu yokutya ye-PVC yinyani. Ngoko, umzekelo, ukupakishwa kweziqhamo kunye neengcambu, iimveliso ze-9 microns zisetyenziswe. Ifilimu ye-10 μm ifanelekile isonka kunye ne-pasta. Iimveliso neemveliso zentlanzi zidinga ifilimu enamandla kakhulu - i-10-14 microns.
Inketho eqhelekileyo-ifilimu ebonakalayo, apho ungabona khona imveliso egcinwe. Ngamanye amaxesha abathengisi balela ifilimu ye-PVC ngomthunzi, umzekelo, uluphuzi ukwenzela ukuba isonka sibonakale sikhangeleke ngokukhethekileyo, okuluhlaza ukutshatyalaliswa kwemifino.
