Kev tsim ntau ntau rau cov ntaub ntawv ntim polyethylene
May 10, 2019
Polyethylene ntim cov ntaub ntawv feem ntau yog tsim los ntawm lub tshuab cua daj cua dub, uas yuav tsum tau siv cov ntawv luam tawm thiab xa tom qab lub tshuab cua daj cua dub tiav. Tshav kub hauv qhov ua kom zoo yog qhov tseem ceeb ntawm lub cev rau kev ntsuam xyuas cov ntaub ntim tshuaj polyethylene. Cov khoom siv hluav taws xob zoo tshaj plaws los xyuas kom meej tias cov khoom siv muaj cua kub ntau hauv lub thawv ntawv tsis zoo, uas yog qhov ua kom lub zog ntim, thiab tsis ntim thaum lub tub yees thiab kev thauj mus los. sib tawg.
Vim li no, ib qho low-density polyethylene muaj lub vos nqaim ntawm cov pa nqus zuj zus yog siv nyob rau hauv txheej kub-sealing txheej kom txhim kho cov cuab yeej kub-sealing ntawm cov khoom ntim polyethylene. Lub LDPE qhov kub qhov kub ntawm qhov kub thiab txias yog qhov dav, thiab qhov kub tho qhov hluav taws xob yog qhov yooj yim dua qhov zoo ntawm LLDPE. Txawm li cas los xij, cov kev tsis zoo yog cov neeg pluag tsis zoo, tsis ua haujlwm, thiab tsis muaj zog. Yog li ntawd, nws yog ib qho tsim nyog ntxiv rau ib qho nqi ntawm LDPE los txhim kho lub npuas ruaj khov thiab txhim kho txoj kev ua tiav extrusion.
Lub tshuab tuaj ntim tshuab tuaj yeem yuav tsum muaj kev sib txhuam tsis sib haum xeeb ntawm cov khoom ntim ntawm polyethylene thiab cov hlau kom cov leeg txav tsis cuam tshuam rau kev ua haujlwm ntau lawm. Yog hais tias kev txhuam coefficient loj, lub qhov hluav taws xob kaw yuav pleated, thiab zaj duab xis pleated yuav thickened thiab kub kaw. Txom nyem, cov pleats yuav tawg thiab tso pa tawm thaum ntog thiab qhov ceev. Yog li, cov txheej txheem nruj heev yog yuam rau cov ntsiab lus ntawm cov khoom siv ntxiv hauv cov luam tawm ntu ntawm cov khoom ntim ntawm polyethylene thiab txheej thawv rau sab nrauv, thiab nws yog ib qho tsim nyog kom ntxiv ib qho nqi ntawm tus neeg qhib lub npe thiab tus neeg muag khoom.
