Taw qhia ntawm PE ob phab ntsa corrugated yeeb nkab ntau lawm kab

PE ob chav phab ntsa corrugated yeeb nkab ntau lawm kab yog ib qho ua tiav cov khoom siv rau kev ua kom siab - ntom polyethylene ob phab ntsa corrugated kav, muaj xws li extruders, pwm, molding tshuab, txiav tshuab, thiab lwm yam. Nws txais PLC tswj system thiab Siemens CNC tshuab, thiab tuaj yeem tsim cov kav dej nrog cov lus qhia los ntawm DN200mm rau DN. Cov yeeb nkab no tau tsim thawj zaug hauv lub teb chaws Yelemees thaum ntxov 1980s. Tom qab ntau tshaj 20 xyoo ntawm txoj kev loj hlob, nws tau nthuav dav los ntawm ib tug ntau yam mus rau ib tug tiav cov khoom kab, thiab cov txheej txheem ntau lawm yog mature. Nws tau dav siv nyob rau hauv cov teb chaws tsim nyob rau hauv cov teb chaws Europe thiab Amelikas, thiab nws cov kev ua tau zoo heev thiab cov txiaj ntsig kev lag luam tau nce hauv kev nce qib thiab kev siv hauv Suav teb.
Cov kab ntau lawm no tsim cov kav dej los ntawm ob chav helix co extrusion qauv thiab kaw lub tshuab nqus tsev txheej txheem, nrog corrugated sab nrauv phab ntsa thiab cov phab ntsa du. Lub extruder tau muab faib ua ob hom: ib leeg ntsia hlau (tsim rau HDPE) thiab conical ntxaib - ntsia hlau (tsim rau PVC), thiab cov qauv khiav tau txais cov qauv sandwich los txhim kho kev hloov pauv. Cov khoom siv yeeb nkab muaj kev ua haujlwm siab rau sab nraud, qhov kub thiab txias ntawm -40℃~ 60 degree, acid thiab alkali corrosion tsis kam, thiab tuaj yeem hloov mus rau qhov tsis sib xws ntawm lub hauv paus thaum tsim kho. Cov khoom siv yog siv nyob rau hauv kev lag luam dej, dej ntws, kev tsim kho, qhov, railway subgrade drainage, thiab lwm yam. Lub nplhaib txhav tsim txuag li 30% ntawm raw khoom noj piv rau cov khoom siv phab ntsa kav.
