Stretch Firimu ine zvakanakira kuoma, kukanganisa kuramba, pachena uye kuzvinamatira.Ingave ichishandiswa kurongedza kurongedza kwezvigadzirwa kana kutakura zvinhu, inogona kudzivirira hunyoro, guruva uye kuderedza basa, kunatsiridza mashandiro, uye kuzadzisa chinangwa chekudzivirira zvigadzirwa uye kuderedza mitengo.Stretch film imhando yekurongedza zvinhu zvinoshandiswa kuunganidza zvinhu.Chimiro chayo chakasiyana ndechekuti inogona kushandisa michina yekutambanudza michina kana kuita manyore kuburitsa kushushikana.Nzira yekudzora sei viscosity yefirimu yakatambanudzwa?

Pane zvinhu zvakawanda zvemufirimu wakatambanudzwa, izvo zvinonyanya kutsamira pamunda wekushandiswa kwechigadzirwa, saka kana iwe uchida kudzora viscosity yefirimu yakatambanudzwa, unogona kushanda nesimba pazvinhu.Haisi yese C4-LLDPE inogona kushandiswa kutambanudza firimu.C6 uye C8 zvinhu zvinowanzoshandiswa nekuda kwekureruka kwavo kugadzirisa.

Kupisa kuchakanganisawo viscosity yefirimu yakatambanudzwa.Kazhinji, tinoisa chigadzirwa munzvimbo ye15 kusvika ku25 degrees.Kana kutonhora kuchipfuura 30 degrees, viscosity ichawedzera;kana yakaderera pane 15 degrees.Panguva iyoyo, viscosity ichadzikira zvakare.Sezvo pachava ne polyethylene mufirimu yakatambanudzwa, tinogona kugadzirisa huwandu hwe polyethylene mumucheka wekunamatira kuti uwane viscosity inoda.

Sezvo kugoverwa kwema molecular uremu hwefirimu yakatambanudzwa kudiki uye huwandu hwekugadzirisa hwakanyanya kutetepa, kazhinji chete 5% ye polyethylene inogona kuwedzerwa kuderedza kunyunguduka viscosity, kuitira kuti flatness yefirimu yakatambanudzwa ivandudzwe.Wedzera flatness yefirimu.
