Food PVC filimu - eziluncedo

I elula Ukutya ifilimu kwithuba elide isetyenziswa nokubopha ukutya. Yenza ngaphandle PVC ngeendlela ezimbini - egalela kwaye bevuthela. A thinner ifilimu efunyanwa inkqubo igalelo sukube.

film ukutya ipropati elikhethekileyo luya ngaphandle kokulahlekelwa amandla ayo. Ngenxa yale nto isetyenziswa njenge impahla. Ukutya PVC ifilimu ilungiselelwe ukuphakheja ngqo iimveliso kurhwebo ngemiyinge iimveliso. It yenziwe ezahlukeneyo kunye yokubhaka iimveliso, inyama, intlanzi, inyama yenkukhu, iziqhamo womile. film Ukutya kwakhona zingasetyenziswa iimveliso ezishushu, ezifana isonka entsha, yaye ngenxa yokwanda ukuxhathisa emafutheni - nokutya okunamafutha. Oku esisetyenziselwa kwiipakethe zemveliso ezahlukeneyo kwicandelo mveliso kule migca zemveliso-high speed nokuhambisa, xa uthungelwano zorhwebo ezahlukeneyo, amashishini nayo kwenkonzo kunye nokutya.

PVC umboniso ithobela imveliso ngokusondeleyo, ngaphandle ukwakha nezibaya zemihlambi. Oku kukuvumela ukuba ayinike nenkangeleko kunokuba nomtsalane, kunciphisa ukusetyenziswa eziphathekayo, ngokunjalo kuqinisekiswe ukhuseleko iphakheji.

Amandla eliphezulu ifilimu kwenza kube afanelekileyo hayi kuphela ukuphakheja ncwadana, kodwa ngenxa matshini. Enye iimpawu eziyimfuneko kwaye iluncedo kakhulu bhanya-bhanya ukutya - self-enamathelayo. Kube lula inkqubo upakisha ngenxa nitrogen lula umbandela ngaphandle kokusebenzisa olongezelelweyo izixhobo itywiniwe. Lo mhlaba ivumela nokupakishwa ngesandla ngaphandle nokusetyenziswa kwezixhobo ezizodwa.

Ukutya PVC filimu nomoya. Kuyinto olukwazi elibaleka igesi kunye umphunga, ngokwenjenjalo linike ixesha elide ulondolozo imveliso kwaye ithintela uphuhliso sande neentsholongwane kwiphakheji.

Ukongeza, umboniso PVC ukhusela imveliso evela zavetrivaniya, ngaloo ndlela bazikhusela inkangeleko yayo yokuqala. Lusetyenziswa kwinkqubo ukupakisha, hayi inyama ekrwada kuphela, kodwa naziphi iimveliso inyama. Ngenxa yayo impahla edlalwa esikhukulayo carbon dioxide neoksijini, iimveliso inyama zahlanganiswa PVC umboniso, kunokugcinwa ixesha elide. Lo mhlaba kuluncedo xa kugcinwa ukutya kunye kwigumbi ebandayo, ekubeni kuthintela ukuyilwa lomkhenkce kuqweqwe lwemiboniso bhanya-bhanya. Ngenxa yale walondoloza amathayara imveliso, layo ixabiso lesondlo kunye ezibalaseleyo.

Ukusetyenziswa PVC ifilimu inzuzo ngaphezu polyethylene oluqhelekileyo. Oku kubangelwa eziliqela zalo eziluncedo:
- amandla eliphezulu;
- ukumelana eliphezulu emafutheni;
- ngqongqo ngokulinganisela;
- elubala ezibalaseleyo kunye isilungiseleli seglosi;
- ukumelana eliphezulu lokuba izinto nochuku;
- ukumelana ubushushu;
- inqanaba eliphezulu iipropati zococeko nesempilweni;
- ukumelana fogging;
- ukukwazi ukugcina isilungiseleli seglosi elubala ixesha elide;
- amathuba ayaphola kwindawo microwave imveliso oveni ziyadakancwa kubushushu ukuya ku-70 ° C.
