Yuav Ua Li Cas Txiav Txim Qhov Zoo Ntawm Stretch Winding Film Yuav?

Stretch wrap film yog ib qho kev nthuav dav ntawm cov ntaub qhwv zaj duab xis, cov ntaub qhwv zaj duab xis muaj ob qho tib si viscosity ntawm cov ntaub qhwv zaj duab xis thiab cov cuab yeej tensile ntawm cov zaj duab xis stretch, uas kuj qhia tau hais tias lub stretch qhwv zaj duab xis yog dav siv. Yuav ua li cas txiav txim qhov zoo ntawm stretch winding zaj duab xis yuav? Cov nram qab no stretch winding zaj duab xis Xiaobian thiab koj qhia txog.
Stretch winding zaj duab xis chaw tsim khoom cov khoom lag luam muaj qhov zoo ntawm kev siv yooj yim, cov txiaj ntsig kev lag luam, thiab peb yuav tsum xyuam xim txheeb xyuas nws qhov zoo thaum peb yuav.

Ua ntej, nws yog ib qho tsim nyog los ntsuas nws cov khoom tensile. Tensile yog lub peev xwm los ncab zaj duab xis qhov txhab tom qab tensile quab yuam. Yog tias qhov zoo yog qhov zoo, qhov ntev yuav txuas ntxiv tom qab ncab, thiab nyob rau hauv ib qho chaw, nws yuav tsis tawg. Tom qab ntawd peb yuav tsum tau them sai sai rau qhov toughness, uas yog, kev ua tau zoo ntawm cov yeeb yaj kiab tiv thaiv kom tawg thiab tsim kua muag. Qhov kev pheej hmoo ntawm kev tsim kua muag yuav tsum yog transverse, uas yog, perpendicular mus rau cov kev taw qhia ntawm lub tshuab ua hauj lwm, vim hais tias tearing nyob rau hauv cov kev taw qhia no yuav ua rau lub pob xoob, txawm tias lub longitudinal tsim kua muag, lub pob yuav nyob twj ywm ruaj, yog li lub zoo dua qhov toughness ntawm stretched winding zaj duab xis yog qhov zoo dua qhov zoo. Qhov thib peb yog nws tus kheej-nplaum, uas yog hais txog adhesion ntawm lub qhov txhab films tom qab kev sib cuag. Cov cuab yeej no tuaj yeem ua rau cov khoom ntim kom nruj thiab tsis xoob thaum lub sijhawm ncab thiab qhwv thiab tom qab qhwv. Ntawm lawv, nws tus kheej viscosity cuam tshuam los ntawm ntau yam sab nraud, xws li cov av noo, plua plav thiab cov pa phem, uas yog qhov tseem ceeb rau kev ntsuas qhov zoo ntawm cov zaj duab xis stretched winding.
