Cov ntaub ntawv tseem ceeb thiab cov yam ntxwv ntawm kev txhaj tshuaj tshuab thiab txhaj tshuaj tshuab cov roj yas ntim lub raj mis
Tam sim no, cov chaw tsim khoom yas sab saum toj ntawm lub khw tuaj yeem xaiv los ntawm ntau yam khoom siv rau kev txhaj tshuaj thiab txhaj tshuaj stretch tshuab raj. Lawv txhua tus muaj lawv tus kheej cov yam ntxwv, lub cev thiab tshuaj lom neeg, thiab tsim cov txheej txheem tsim thiab molding. Cov hauv qab no feem ntau qhia txog cov yam ntxwv, daim ntawv thov teb, thiab daim ntawv thov ntawm cov ntaub ntawv yas uas tuaj yeem siv rau kev txhaj tshuaj tshuab thiab txhaj tshuaj stretch tshuab molding.
High-density Polyethylene (HDPE)
Cov khoom siv PE ntxov tshaj plaws siv hauv lub raj mis tshuab yog cov polyethylene tsawg. Tom qab ntawd, nrog kev txhim kho ntawm HDPE, vim nws cov khoom siv dav dav, kev ua haujlwm zoo, thiab tus nqi. Nws yog dav siv rau cov khoom siv niaj hnub, tshuaj, ntim tshuaj pleev ib ce, thiab ntim khoom kom haum rau cov tshuaj zawv plaub hau.
HDPE muaj qhov hloov tau zoo rau cov txheej txheem molding, siab thermal stability, thiab dav ua haujlwm kub ntau, thiab feem ntau yog siv rau hauv extrusion tshuab moulding thiab txhaj tshuaj molding. Ntawm lawv, txhaj tshuaj molding muaj qhov zoo tshaj plaws hauv kev siv cov ntim me me HDPE fwj hauv tshuaj, tshuaj pleev ib ce, thiab zaub mov vim qhov tseeb qhov tseeb ntawm lub qhov ncauj, thiab tau dhau los ua cov khoom tseem ceeb tshaj plaws hauv cov txheej txheem txhaj tshuaj.
