Cov yam ntxwv cuam tshuam rau Stretch Film Viscosity

Stretch zaj duab xis nws tus kheej muaj qee yam viscosity, uas muaj kev sib raug zoo nrog nws cov khoom siv raw. Raws li cov khoom ntim uas muaj nyob rau hauv kev lag luam logistics, yog tias nws cov viscosity siab, lub ntim ntawm cov khoom yuav raug txhim kho. Nws ruaj khov dua, tab sis thaum lub viscosity txo qis, kev tiv thaiv kev ua haujlwm yuav txo qis, yog li nws yuav ua rau qee yam kev puas tsuaj. Yog li ntawd, txhawm rau txo qhov tshwm sim ntawm qhov xwm txheej no, peb yuav tsum nrhiav cov yam ntxwv uas cuam tshuam rau nws cov viscosity thiab zam kom tsis txhob muaj sijhawm. Tshwj xeeb, peb luv luv qhia nws hauv qab no.

(1) Muaj ntau yam khoom siv rau kev ua yeeb yaj kiab, uas feem ntau yog nyob ntawm daim ntawv thov teb ntawm cov khoom, yog li yog tias koj xav tswj nws cov viscosity, koj tuaj yeem ua haujlwm hnyav ntawm cov khoom. Nws tsis haum rau txhua yam ntaub ntawv C4-LLDPE. C6 thiab C8 cov ntaub ntawv feem ntau siv vim lawv yooj yim rau kev ua, thiab qhov kub thiab txias kuj tseem yuav cuam tshuam rau nws cov viscosity. Feem ntau, peb yuav muab cov khoom tso rau ntawm qhov kub ntawm kaum tsib mus rau nees nkaum tsib degrees. Nyob rau hauv ib puag ncig, yog tias qhov kub siab tshaj 30 degrees, viscosity yuav nce; Yog tias nws qis dua 15 degrees, viscosity yuav deteriorate dua.

(2) Txij li thaum muaj cov khoom siv polyethylene hauv cov zaj duab xis ncab, peb tuaj yeem kho tus nqi ntawm polyethylene hauv cov nplaum txheej kom ua tiav qhov xav tau viscosity; vim tias qhov hnyav molecular faib ntawm cov zaj duab xis ncab yog qhov nqaim thiab qhov kev ua haujlwm yog qhov nqaim, yog li feem ntau tsuas yog tsib feem pua ​​​​ntawm polyethylene tuaj yeem muab ntxiv los txo cov yaj viscosity, yog li ntawd nws cov flatness kuj tseem yuav txhim kho kom cov flatness ntawm cov khoom. zaj duab xis.

Yog li txhua tus neeg yuav tsum nkag siab tias qhov viscosity ntawm cov yeeb yaj kiab stretch yog ib qho tseem ceeb hauv kev txiav txim siab qhov zoo ntawm cov khoom. Yog tias cov khoom poob nws qhov kev tiv thaiv, qhov tseem ceeb ntawm cov khoom no yog dab tsi? Vim nws tsis muaj qab hau, nws yuav tsis muaj txiaj ntsig thiab muaj txiaj ntsig thaum siv nws.
