Namuhla kunzima ukukholelwa kulokhu, kodwa maduzane, izikhwama zepulasitiki ziye zaba yixabiso elikhulu ngisho nokuntuleka, futhi akuyona enye yezinhlobo zokupakisha ezilahlayo. Ngenhlanhla izikhathi zishintshile ukuze zibe ngcono futhi cishe kuzo zonke ikhishi ungathola umqulu wokudla i-polyethylene noma i-polyvinyl i-chloride ifilimu. Abazizwayo bayakwazisa zonke izici ezinhle zale ndaba futhi basebenzise ngempumelelo enkulu yokugcina imikhiqizo, ukupakisha amaphasela ahlukahlukene nokupheka. Futhi konke okuthakazelisayo kakhulu ngefilimu yokudla ongayifunda kusuka kusihloko sethu.
Ifilimu yemikhiqizo yokudla
Okokuqala, masijwayele i-heroine ye-athikili yethu eduze. Ifilimu yokudla ingaba yi-polyethylene noma i-polyvinyl chloride (PVC). Futhi nakuba kunzima kumuntu omele ukuhlukanisa omunye nomunye ekuboneni kokuqala, kukhona ukungafani okuhlukile kwezici zabo. I-main one igcwalise ngokuphelele igesi namanzi ukumelana nefilimu ye-polyethylene ngokuphambene nalokho okushiwo "ukuphefumula" kwesihlobo se-PVC. Kulokhu, ifilimu eyenziwe ngezingxenye ezimbalwa ezincane ze-polyethylene ingasetshenziswa kuphela ukudla okubandayo, isibonelo, ukupakisha ama- scraps , imifino, izithelo, isinkwa. Imikhiqizo ngaphansi kwegobolondo elinjalo ngeke ivezwe emiphumeleni ewonakalisayo yemvelo futhi izothola ngokugcwele izakhiwo zayo kuyo yonke impilo yomkhiqizo. Umzamo wokupakisha into epulasitiki yokugubungela ipulasitiki kuzophela ku-fiasco ephelele: izovele ihlehlise futhi ilahlekelwe izindawo zayo zokuzivikela. Akuyona indlela engcono kakhulu, i-polyethylene iphendula ngokudonsa isikhathi eside ekushiseni - efrijini iyoba yilapho iguquguquke futhi ibe yincwajana. Kodwa i-PVC-ifilimu izobhekana ngokugcwele nemikhiqizo yokudla eshisayo neqhwa, futhi isidlo ngaphansi kwayo ngeke silahlekelwe ukuheha kwayo futhi ngeke sibe nenkungu. Ngaphezu kwalokho, cishe ayinandaba namafutha nama-acids, okwenza kube yisisombululo esihle sokupakisha izitsha eziphekiwe. Ngaphezu kwalokho, ikhono lokumelana nokushisa okuphakeme ngokwanele kwenza kube lula ukusebenzisa leyo filimu ngisho nasesitheni se-microwave, isibonelo, ukuvuselela izitsha ngaphandle kokukhipha amaphakheji. Ngaphezu kwalokho, amafilimu anjalo ahambisana kakhulu - kokubili lezi zinto zinekhono lokusula cishe ubude bawo obuqala cishe izikhathi ezintathu futhi zihambelane ngokuphelele kunoma iyiphi indawo. Konke lokhu kukuvumela ukuba uphathe ngokushesha imikhiqizo yimuphi umumo nosayizi, ngaphandle kokusebenzisa noma yiziphi izinkampani zangaphandle kanye nama-latches. Futhi kungenziwa kokubili ngosizo lwemishini yokupakisha ekhethekile, nangokuhambisa umqulu wefilimu ngesandla.
Yehlisa ifilimu yokudla
Indawo ekhethekile phakathi kwezinto zokupakisha zokudla ihlehlisa ifilimu. Isici sawo esivela yikhono lokusebenzisana ngaphansi kwethonya lokushisa futhi uthathe isimo sezinto okufanele zipakishwe. Uthole uhlelo olubanzi kunabo bonke emkhakheni wokuhweba, lapho imikhiqizo ehlukahlukene yokudla ihlanganisiwe kuleyo filimu. Kulokhu, ifilimu igcina ukukhanya okukhulu, ngakho-ke umthengi unethuba kuwo wonke umuntu
Ukuqina kwefilimu yokudla
Ifilimu ejwayelekile ye-polyethylene yokudla iyatholakala ngobuningi bamamitha ayi-6, 7.5 noma angu-8. Ifilimu ye-PVC yokudla, le pharamitha ingaba yi-8, 9, 10, 12 noma i-microns ayi-14. Uma ukhetha ubukhulu, kufanele ugxile kulohlobo lwemikhiqizo ezobekwa emaphaketheni. Ngakho-ke, ukuze upake amajikijolo, izithelo, amakhowe kanye nemifino, ifilimu ye-PVC enobukhulu be-microns ayi-9. Futhi ngokudla, inhlanzi kanye nemikhiqizo esiphelile, udinga ukuthatha ifilimu ngobukhulu bama micrononi angu-12-14.
