Kev nyab xeeb thiab siv cov khoom siv hluav taws xob zoo, ua ke nrog kev teeb tsa thiab cov kav dej kom raug, yog qhov tseem ceeb hauv kev lag luam uas tso siab rau cov kav dej, tshwj xeeb tshaj yog thaum cov tshuab no siv los thauj roj, dej, lossis lwm yam kua dej tseem ceeb.
Thaum lub tshuab hluav taws xob siv hluav taws xob muaj kev ntseeg siab thiab muaj txiaj ntsig zoo los koom nrog cov kav dej polyethylene (PE), qhov xwm txheej tsis ntev los no, zoo li ib qho hauv Australia qhov twg cov khoom sib txuas tau tawg vim kev teeb tsa tsis raug, ib zaug ntxiv hais txog qhov tseem ceeb ntawm cov qauv kev nyab xeeb thiab kev cob qhia kom raug rau cov kws tshaj lij.
Qhov xwm txheej Australia: Ib qho kev ceeb toom tseem ceeb ntawm kev pheej hmoo ntawm kev teeb tsa
Thaum Lub Xya Hli 22, 2024, qhov tawg tau tshwm sim ntawm Cadia Mine, NSW, thaum lub sijhawm ua haujlwm electrofusion vuam cuam tshuam nrog cov khoom siv HDPE.
Ob tug neeg ua haujlwm tau txuas lub raj xa dej hauv qhov av thaum qhov txheej txheem vuam tsis zoo, ua rau muaj xwm txheej hnyav.
Txoj kev tshawb nrhiav pom tias cov ntaub ntub dej abrasive thiab cov ntaub so ntswg tau siv los ntxuav cov yeeb nkab kawg, uas yuav ua rau muaj kev tawg. Tom qab ua tiav qhov vuam, cov neeg ua haujlwm tawm ntawm thaj chaw; Thaum lawv rov qab los, lawv pom cov pa taws, thiab tsis ntev tom qab ntawd, qhov tawg tau tshwm sim, tawg cov khib nyiab tshaj 60 meters.
Hmoov zoo, tsis muaj kev raug mob.
Qhov xwm txheej no qhia txog qhov xav tau tseem ceeb rau kev npaj kom raug thiab ua raws li cov txheej txheem kev nyab xeeb thaum electrofusion vuam.
Siv cov kev tu tsis tsim nyog, xws li cov tshuab abrasive, tuaj yeem ua rau muaj kev pheej hmoo loj, hais txog cov txheej txheem kom raug yuav tsum tau ua kom muaj kev ruaj ntseg.
