Yuav ua li cas txheeb xyuas qhov zoo ntawm Stretch Wrapping Film

Cov khoom ntawm stretch film manufacturers muaj qhov zoo ntawm kev siv yooj yim thiab kev lag luam, thiab thaum peb yuav, peb yuav tsum xyuam xim rau kev txheeb xyuas nws qhov zoo.

Ua ntej tshaj plaws, nws cov khoom tensile yuav tsum tau kuaj. Stretching yog lub peev xwm ntawm stretch qhwv zaj duab xis los tsim elastic elongation tom qab ncab. Yog tias qhov zoo yog qhov zoo, qhov ntev yuav txuas ntxiv tom qab ncab, thiab nyob rau hauv ib qho kev txwv, nws yuav tsis tawg. . Tom qab ntawd xyuam xim rau qhov toughness, uas yog hais txog kev ua tau zoo ntawm cov yeeb yaj kiab tiv thaiv kev sib tsoo thiab kua muag. Tus nqi txaus ntshai ntawm kev tsim kua muag yuav tsum tau coj mus rau hauv txoj kev hloov pauv, uas yog, perpendicular mus rau cov kev taw qhia ntawm lub tshuab ua haujlwm, vim hais tias tearing nyob rau hauv cov kev taw qhia no yuav loosen lub pob, txawm hais tias lub longitudinal tear tshwm sim, lub pob tseem tuaj yeem ruaj khov, yog li qhov zoo dua qhov toughness ntawm stretch wrapping zaj duab xis, qhov zoo dua qhov zoo. Qhov thib ob yog nws tus kheej-adhesion, uas yog hais txog adhesion ntawm lub wrapping films tom qab kev sib cuag. Cov yam ntxwv no tuaj yeem ua rau cov khoom ntim tau nruj yam tsis tau xoob thaum lub sij hawm stretch wrapping txheej txheem thiab tom qab qhwv.

Ntawm lawv, nws tus kheej adhesion yog cuam tshuam los ntawm ntau yam sab nraud, xws li cov av noo, plua plav thiab cov pa phem, thiab lwm yam, uas yog ib qho tseem ceeb qhia kom paub qhov zoo ntawm stretch wrapping zaj duab xis.
