Cov Ntawv Polyethylene Ceev Siab (HDPE/PE300)
Kev piav qhia:
Daim ntawv Polyethylene PE300 - HDPE yog cov yas engineering uas sib dua thiab muaj zog nrog lub zog cuam tshuam siab. Nws kuj muaj kev tiv thaiv tshuaj zoo heev nrog kev nqus dej tsawg heev thiab tau txais kev pom zoo los ntawm FDA. HDPE kuj tseem tuaj yeem tsim thiab vuam. Daim ntawv Polyethylene PE300.
Cov Nta Tseem Ceeb ：
Tsim los ua ib qho ntawm cov yas uas siv tau ntau yam tshaj plaws hauv ntiaj teb, polyethylene uas muaj zog ntau muaj ntau yam txiaj ntsig. Peb cov HDPE tau tsim los kom siv tau ntev, tsis tas yuav saib xyuas ntau, thiab muaj kev nyab xeeb. Cov khoom siv no tau txais kev pom zoo los ntawm FDA rau kev siv hauv kev lag luam ua zaub mov, thiab nws muab cov txiaj ntsig ntxiv ntawm kev tiv taus dej noo, xim av, thiab tsw ntxhiab.
Ntxiv rau ntau yam txiaj ntsig teev saum toj no, HDPE tiv taus xeb, txhais tau tias nws tsis tawg, lwj, lossis khaws cov kab mob phem. Qhov tseem ceeb no, nrog rau nws txoj kev tiv taus huab cua, ua rau HDPE zoo meej rau kev siv hauv thaj chaw uas ntsib dej, tshuaj lom neeg, cov kuab tshuaj, thiab lwm yam kua dej.
HDPE kuj paub tias muaj qhov sib piv ntawm lub zog thiab qhov ceev (xws li 0.96 txog 0.98 g), tab sis nws yooj yim yaj thiab pwm tau. Nws tuaj yeem txiav, tshuab, tsim, thiab vuam thiab / lossis mechanically fastened kom tau raws li qhov xav tau ntawm ntau daim ntawv thov.
Thaum kawg, zoo li ntau yam yas uas tau tsim, HDPE yooj yim siv dua tshiab thiab tuaj yeem pab txo cov khib nyiab yas thiab kev tsim khoom.

Daim ntawv loj:
Ntawm Beyond Plastics, HDPE muaj ntau qhov ntau thiab tsawg, duab, tuab, thiab xim. Peb kuj muab cov kev pab txiav CNC los pab koj kom tau txiaj ntsig ntau tshaj plaws thiab txiav koj cov nqi tag nrho.
Daim Ntawv Thov:
Ua tsaug rau qhov ua tau ntau yam ntawm cov polyethylene uas muaj zog heev, ntau lub tuam txhab tsim khoom feem ntau hloov lawv cov khoom siv qub hnyav dua nrog HDPE. Cov khoom no siv thoob plaws ntau yam lag luam suav nrog kev ua zaub mov, tsheb, nkoj, kev ua si, thiab ntau ntxiv!
Cov khoom ntawm HDPE ua rau nws yog ib qho kev xaiv zoo rau kev siv sab hauv tsev thiab sab nraum zoov, suav nrog:
Cov Kab Ntim Thiab Cov Tshuab Nqa Khoom
Cov Rooj Txiav
Rooj Tog Sab Nraum Zoov
Cov Ntawv Qhia Khoom Siv thiab Cov Cheebtsam
Cov paib, cov khoom siv, thiab cov zaub
Ntawm lwm yam, HDPE kuj tseem siv rau hauv lub raj mis, cov phaj ncaws pob, cov thoob roj, cov txee dai khaub ncaws, cov khoom siv ua si, cov ntim khoom, cov thoob dej, cov khoom siv ua zaub mov, cov ntaub thaiv qhov rooj, thiab cov nkoj, RV, thiab cov tsheb thaum muaj xwm txheej ceev.
Peb tuaj yeem muab ntau yam UHMWPE / HDPE / PP / PA / POM / daim ntawv raws li qhov xav tau sib txawv hauv daim ntawv thov sib txawv.
