Kev nyab xeeb ntawm cov xov hluav taws xob yog qhov tseem ceeb hauv kev lag luam, tshwj xeeb tshaj yog thaum nws los txog rau kev cim cov xov hluav taws xob uas tsis muaj pa luam yeeb thiab tsis muaj halogen. Cov xov hluav taws xob uas tsis muaj pa luam yeeb thiab tsis muaj halogen (LSHF) yog tsim los txo qhov kev tso pa luam yeeb thiab cov pa roj lom thaum muaj hluav taws, ua rau lawv yog qhov kev xaiv zoo dua rau cov chaw kaw lossis cov chaw muaj neeg coob coob. Kev txheeb xyuas cov xov hluav taws xob no yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev ua raws li koj qhov kev teeb tsa hluav taws xob. Yog li yuav ua li cas txheeb xyuas cov xov hluav taws xob uas tsis muaj pa luam yeeb thiab tsis muaj halogen? Tom ntej no, peb yuav coj koj mus rau kev nkag siab txog txoj kev txheeb xyuas cov xov hluav taws xob uas tsis muaj pa luam yeeb thiab tsis muaj halogen.
1. Txoj kev hlawv ntawm qhov chaw rwb thaiv tsev. Cov txheej rwb thaiv tsev yuav tsum tau ironed kom tsis txhob muaj qhov tob tob, thiab yog tias muaj qhov tob tob loj, nws qhia tau tias cov khoom siv lossis cov txheej txheem siv hauv cov txheej rwb thaiv tsev tsis zoo. Los yog ci nrog lub teeb, nyob rau hauv qhov xwm txheej ib txwm yuav tsum tsis yooj yim rau hluav taws, cov txheej rwb thaiv tsev ntawm lub cable tseem ua tiav tom qab lub sijhawm ntev ntawm kev hlawv, tsis muaj pa luam yeeb thiab ntxhiab tsw khaus, thiab lub cheeb tau nce. Yog tias nws yooj yim rau hluav taws, koj tuaj yeem paub tseeb tias cov txheej rwb thaiv tsev ntawm lub cable tsis yog ua los ntawm cov khoom siv uas tsis muaj pa luam yeeb halogen tsawg (feem ntau yog polyethylene lossis crosslinked polyethylene). Yog tias muaj pa luam yeeb loj, nws txhais tau tias cov txheej rwb thaiv tsev siv cov khoom siv halogenated. Yog tias tom qab lub sijhawm ntev ntawm kev hlawv, qhov chaw rwb thaiv tsev poob qis heev, thiab lub cheeb tsis nce ntau, nws qhia tau tias tsis muaj kev kho mob crosslinking irradiation tsim nyog.
2. Txoj kev sib piv qhov ceev. Raws li qhov ceev ntawm dej, cov khoom yas raug muab tso rau hauv dej. Yog tias nws poob, cov yas yuav ntom dua dej, thiab yog tias nws ntab, cov yas yuav ntom dua dej. Txoj kev no tuaj yeem siv ua ke nrog lwm txoj kev.
3. Kev txheeb xyuas cov kab hluav taws xob uas tsis muaj pa luam yeeb halogen los ntawm kev ntub dej kub. Lub plawv hlau lossis cable raug ntub dej kub ntawm 90 ℃, feem ntau, qhov tsis kam ntawm rwb thaiv tsev yuav tsis poob sai, thiab tseem nyob siab dua 0.1MΩ/Km. Yog tias qhov tsis kam ntawm rwb thaiv tsev poob qis dua 0.009MΩ/Km, nws qhia tias cov txheej txheem irradiation crosslinking tsim nyog tsis tau siv.
