Daim ntawv thov ntawm HDPE: Nws tuaj yeem siv rau extrude ntim zaj duab xis, hlua, hnab woven, nuv ntses nets, kav dej; txhaj tshuaj qis-qib niaj hnub tsim nyog thiab cov plhaub, cov khoom siv tsis-load-cov kabmob, cov thawv yas, cov thawv hloov pauv; extrusion tshuab molding ntim, hollow khoom, fwj. Txhaj tshuaj molding txheej txheem ntawm HDPE: HDPE muaj suav tsis txheeb daim ntaub ntawv, xws li reusable nyias-walled haus khob mus rau 5-gsl cov kaus poom, haus 1/5 ntawm HDPE ua domestically. Cov qib txhaj tshuaj molding feem ntau muaj qhov ntsuas qhov ntsuas ntawm 5 txog 10, thiab muaj cov qib fluidity qis dua nrog toughness thiab qib fluidity ntau dua nrog cov machinability. Kev siv muaj xws li cov khoom siv nyias nyias thiab ntim khoom noj; tawv, khoom noj khoom haus thiab cov xim pleev xim; siab tsis kam mus rau ib puag ncig kev ntxhov siab tawg daim ntaub ntawv xws li lub cav me me roj tso tsheb hlau luam thiab 90-gal thoob khib nyiab. Feem ntau, HDPE muaj qhov melting point ntawm 142 degree thiab decomposition kub ntawm 300 degree; qhov adjustable ntau yam ntawm txhaj tshuaj molding kub yog kuj loj. Thaum lub sij hawm txhaj tshuaj molding, qhov dav siv kub yog 180 degree -230 degree ; vim nws yog cov yas olefin, nws tsis nqus dej, thiab tsis tas yuav qhuav thaum lub sij hawm tsim khoom, tab sis rau cov khoom zoo, nws tuaj yeem qhuav ntawm 60 degree rau 1 teev kom tso dej ntws tawm; polyethylene Lub yaj viscosity ntawm cov khoom yog siab, qhov ntws ntev piv yog me me, thiab cov khoom uas nyias nyias yuav tsis muaj kua nplaum, yog li lub rooj vag thiab cov khiav yog qhov loj; cov khoom yog ib qho yooj yim kom tau them nrog hluav taws xob zoo li qub, thiab qhov saum npoo yog yooj yim nqus.
