Thaum siv cov polypropylene liner es tsis txhob polyethylene liner
Kev siv cov zais tsiaj ntawm FIBC tau nce ntau zuj zus. Raws li qhov ntau zaus ntawm kev siv lub hnab loj hauv cov khoom noj, tshuaj lag luam thiab tshuaj lom neeg kev lag luam nce, muaj kev xav kom nkag siab zoo dua uas cov khoom thiab cov ntawv thov siv twg hom cov kab hauv.
Txhawm rau siv cov kab FIBC ntim cov hnab ntim tau zoo thiab siv tau zoo, nws yog qhov tseem ceeb kom paub tias lub hnab twg siv. Tsis muaj cov txheej txheem polyethylene yeeb yaj kiab tsis txaus hauv qee yam xwm txheej. Feem ntau, cov kab xev polyethylene tsis muaj txhij txhua thaum cov khoom lag luam siab yuav koom nrog.
Qee qhov txwv rau Cov Qauv FIBC hnab yas
Rau feem ntau ntawm cov kev thov, ib tus qauv polyethylene liner txaus. Cov hnab yas polyethylene muaj ntau heev nyob rau hauv kev lag luam zaub mov thiab chaw muag khoom. Tiv thaiv kev ua kom tsis huv los ntawm kev nkag mus rau cov khoom yog qhov tseem ceeb tshaj plaws, tab sis cov kab xev no muaj kev txwv. Tshwj xeeb tshaj yog, nws tsis tuaj yeem tiv taus kub li ntawm 170 thiab 195 degrees Fahrenheit. Cov khoom siv polyethylene yuav pib ua kom mos thiab yaj. Qhov no tuaj yeem ua rau kom tsis muaj kev cuam tshuam ntawm cov khoom. Hauv cov xwm txheej no, nws yog qhov yuav tsum tau siv cov hnab looj coj los ntawm cov khoom sib txawv kiag li.
Cov hnab polypropylene rau lub hnab ntim khoom loj
Polypropylene liners yog qhov tsim nyog rau cov xwm txheej uas ib txheej roj uas muaj peev xwm tiv taus qhov kub siab tshaj 170 degrees Fahrenheit yuav tsum ua. Lawv feem ntau yog cov tuab dua thiab muaj zog dua li cov qauv polyethylene hnab. Cov no tsis yog tshwm sim ntau vim tias lawv tsuas yog siv nyob rau qee qhov xwm txheej tshwj xeeb. Txawm li cas los xij, lawv tuaj yeem tiv taus cov khoom lag luam mus txog 295 degrees Fahrenheit, siab dua qhov tsis suav ntawm FIBC txuj (200 degrees Fahrenheit) thiab siab dua li polyethylene liner txheem. (170 degrees Fahrenheit) yog qhov tseem ceeb.
