Thaum siv ntau cov pwm PE yeeb nkab cov khoom siv, puas yog pwm ntau dua?
Cia peb tham luv luv txog nws. Plaub-pwm PE yeeb nkab ntau lawm kab tsim plaub PE kav tib lub sijhawm. Nyob rau ntawm qhov chaw ntawm kev ua kom cov khoom zoo, kev siv cov cuab yeej no tuaj yeem txo cov nqi peev txheej, cov nqi cog qoob loo thiab cov nqi tsim khoom lag luam, ua kom cov zis ntau ntxiv, thiab txo lub sijhawm ntau lawm. Feem ntau hais lus, txoj kab uas hla ntawm cov kav dej ntau lawm yog 16mm-32mm.
Cov zis ntawm 4-strand PE yeeb nkab ntau lawm kab tau nce 70 feem pua thaum tswj cov khoom zoo ntawm 2-strand PE yeeb nkab ntau lawm kab. Lub tshuab txiav ib feem ntawm 4-strand yeeb nkab ntau lawm kab tsis ua kom muaj zog noj. Tom qab cov kab ntau lawm pib ib txwm, lub suab nrov zoo ib yam li ntawm 2-strand yeeb nkab extruder. Nws yog xav tias qhov txiav ntawm 4-strand PE yeeb nkab ntau lawm kab yog txiav los ntawm ib tug saw hniav thiab lub tog raj kheej yog cia li thawb. Yog li ntawd, tsis muaj kev txiav chips nyob rau hauv tag nrho cov kab ntau lawm thiab yeej tsis muaj plua plav paug.
