Firimu yekudyaimhando yezvigadzirwa zvepurasitiki zvekurongedza, zvinowanzo gadzirwa nepolymerization reaction ine ethylene se masterbatch.
Inogona kukamurwa muzvikamu zvitatu
Yokutanga ndeye PE , Inonyanya kushandiswa kurongedza chikafu.Iyi firimu inoshandiswa kune michero nemiriwo yatinowanzo tenga, kusanganisira iyo semi-yakapedzwa zvigadzirwa zvinotengwa musupermarket.
Yechipiri ndeyePVC.Ichi chinyorwa chinogona zvakare kushandiswa kurongedza chikafu, asi chine kumwe kukanganisa pakuchengetedza kwemuviri wemunhu;
Yechitatu PVDC, iyo inonyanya kushandiswa kurongedza chikafu chakabikwa, ham uye zvimwe zvigadzirwa.
Tambanudza firimuinogadzirwa nekushandisa kunze kwenyika mutsara polyethylene LLDPE resin uye yakakosha tackifier additives.
1. Kushandiswa kwakasiyana
Firimu rekudya: dzakasiyana siyana dzekushandisa, kusanganisira kurongedza chikafu, michero, muriwo, nyama, uye zvinyorwa kurongedza.
Stretch firimu: kurongedza, pamwe nekudzivirira kurongedza kwezvinhu panguva yekufambisa, kunyanya kudzivirira zvinhu kuti zvipararire kana kukweshwa.
2. Madiro akasiyana
Ukobvu hwefirimu yakatambanudzwa hwakanyanya kudarika firimu yezvokudya, uye ukuru hukuru kupfuura firimu yezvokudya.
Pepa repurasitiki repamba rinowanzoita 30cm muhupamhi uye 10um muukobvu;firimu rakatambanudzwa maindasitiri rinowanzoita 50cm muhupamhi uye 20um muukobvu.
3. Different stretch ratio
Firimu rekutamba rinotambanuka kupfuura firimu rekudya.Stretch firimu rinopeperetswa zvakananga kubva kuLDPE kuburikidza nemuchina wekuvhuvhuta, uye chiyero chayo chekutambanudza chinogona kusvika 300% -500%.Panguva imwecheteyo, firimu yezvokudya inonamatira kune chinyorwa, nepo firimu yakatambanudzwa inozvinamatira, iyo inobatana nehuwandu hwe polyisobutylene inoshandiswa.
LGLPAK inotarisa pakutsvagisa nekusimudzira uye kugadzirwa kwezvigadzirwa zvepurasitiki, kupa vatengi zvigadzirwa zvinogutsa ndizvo zvatinotsvaga.
