LGLPAK yanga yakatarisana nezvigadzirwa zvepurasitiki, uye kuputira kwepurasitiki chinhu chakajairika.
Cling firimu imhando yepurasitiki yekurongedza chigadzirwa, kazhinji inogadzirwa nepolymerization reaction ine ethylene seye master batch.
Firimu yekudya inogona kukamurwa muzvikamu zvitatu:
yekutanga ndeye polyethylene, inonzi PE;
yechipiri inonzi polyvinyl chloride, inonzi PVC;
Yechitatu inonzi polyvinylidene chloride, kana PVDC kwenguva pfupi.
Microwave chikafu chekudziya, kuchengetedza chikafu chefiriji, kurongedza chikafu chitsva uye chakabikwa uye zvimwe zviitiko, mumunda wehupenyu hwemhuri, zvitoro zvesupermarket, mahotera nemaresitorendi, uye kurongedza chikafu mumaindasitiri, mazhinji ekuputira epurasitiki uye anowanzo shandiswa mabhegi epurasitiki anotengeswa pamusika. inogadzirwa neEthylene masterbatch ndiyo yakabikwa.
Zvinoenderana nemhando dzakasiyana dze ethylene masterbatch, firimu rekudya rinogona kukamurwa muzvikamu zvitatu.
Yekutanga ndeye polyethylene, kana PE kwenguva pfupi.Nyaya iyi inonyanya kushandiswa kurongedza chikafu.Iyo firimu yatinowanzo tenga kune michero nemiriwo, kusanganisira semi-yakapera zvigadzirwa zvakatengwa kubva kuchitoro, zvese zvinoshandiswa kune izvi zvinhu;
Rudzi rwechipiri ndeye polyvinyl chloride, kana PVC kwenguva pfupi.Ichi chinyorwa chinogona zvakare kushandiswa kurongedza chikafu, asi chine kumwe kukanganisa pakuchengetedza kwemuviri wemunhu;
Rudzi rwechitatu polyvinylidene chloride, kana PVDC kwenguva pfupi, iyo inonyanya kushandiswa kurongedza chikafu chakabikwa, ham uye zvimwe zvigadzirwa.
Pakati pemhando nhatu dzekuputira epurasitiki, PE nePVDC kuputira kwepurasitiki yakachengeteka kumuviri wemunhu uye inogona kushandiswa nekuvimba, nepo PVC yekuputira ine carcinogens uye inokuvadza zvakanyanya kumuviri wemunhu.Naizvozvo, kana uchitenga kuputira kwepurasitiki, Kwete-chepfu inofanira kushandiswa.
Kubva pakuona kwemuviri, firimu rekudya rine mwero weokisijeni permeability uye kunyorova kwemvura, inogadzirisa okisijeni uye unyoro hwemukati zvakapoteredza chigadzirwa chekuchengetedza chitsva, inovhara guruva, uye inorebesa nguva yekuchengetedza patsva kwechikafu.Nokudaro, zvakakosha kusarudza zvakasiyana-siyana zvepurasitiki zvezvokudya zvakasiyana.
Mushure mekunzwisisa, munhu wese anofanira kuterera kune sarudzo pakusarudza firimu rekudya muhupenyu hwezuva nezuva kudzivirira zvinhu zvine chepfu.
