2. Lub sijhawm ua kom sov ntev dhau, cov khoom PVC laus zuj zus, kub hnyiab; Ua kom lub sijhawm ua kom sov luv dua, xyuas seb puas muaj teeb meem nrog lub tshuab ua kom sov, thiab saib xyuas raws sijhawm.
02. Cov khoom PVC tsis yog yas.
1. Qhov kub qis dhau; qhov nce ntxiv tsim nyog yuav ua tau.
2. Thaum ua cov yas granulating, cov yas sib xyaw tsis sib npaug lossis muaj cov khoom me me hauv cov yas uas nyuaj rau ua kom yas; Lub tes tsho pwm tuaj yeem nruab nrog cov khoom me me, txhim kho qhov siab ntawm lub qhov ncauj kua nplaum.
03. Tshem tawm cov tuab tsis sib xws thiab cov duab slub
1. Vim yog qhov tsis ruaj khov ntawm cov ntsia hlau thiab kev rub, ua rau cov khoom tuab tsis sib xws, vim muaj teeb meem ntawm lub nplhaib nruj, yooj yim tsim cov xyoob, pwm me dhau, lossis lub hauv paus cable hloov pauv, ua rau muaj kev hloov pauv ntawm cov tuab.
2. Feem ntau xyuas qhov traction, ntsia hlau, thiab lub cuab yeej rub lossis qhov ceev, hloov kho raws sijhawm; Cov pwm sib phim yuav tsum tsim nyog kom tiv thaiv kev nchuav kua nplaum; saib xyuas qhov hloov pauv sab nraud ntau zaus.
04.Cov khoom siv cableextrusion pores thiab npuas
1. Ua los ntawm kev tswj qhov kub hauv zos uas kub heev; pom tau tias yuav tsum tau kho qhov kub kom raws sijhawm thiab tswj kom nruj me ntsis.
2. Yas tshwm sim los ntawm cov dej noo lossis dej; Pom tias yuav tsum tau nres hauv lub sijhawm thiab cov dej noo.
3. Yuav tsum ntxiv cov cuab yeej ziab; ziab cov khoom ua ntej siv.
4. Lub hlau tseem ceeb yuav tsum tau preheated ua ntej yog tias nws ntub.
05. Cov khoom siv cable extrusion tsis zoo
1. Kev tswj qhov kub tsawg, kev ua kom yas tsis zoo; Tswj qhov kub raws li cov txheej txheem.
2. Kev puas tsuaj ntawm pwm; Kho dua lossis tshem tawm cov pwm puas tsuaj.
3. Qhov kub ntawm lub taub hau qis, kev nplaum yas tsis zoo; Ua kom qhov kub ntawm lub taub hau nce siab.
06. PVC cov khoom extrusion nto tsis zoo
1. Cov roj hmab uas nyuaj rau plasticize yog extruded yam tsis muaj plasticization, ua rau muaj cov ntsiab lus me me thiab cov khoom me me ntawm qhov chaw, faib nyob ib puag ncig qhov chaw; Qhov kub yuav tsum tau nce kom haum lossis qhov ceev ntawm txoj kab traction thiab qhov ceev ntawm lub hau yuav tsum tau txo qis.
2. Thaum ntxiv cov ntaub ntawv, cov khoom tsis huv yuav tsum sib xyaw nrog cov khoom tsis huv; Thaum ntxiv cov ntaub ntawv, cov khoom tsis huv yuav tsum tsis txhob sib xyaw, thiab cov khoom tsis huv yuav tsum tau ntxuav tam sim ntawd thiab cov kua nplaum yuav tsum tau ntxuav.
3. Thaum lub cable core hnyav dhau, qhov kev nruj me me, thiab qhov txias tsis zoo, qhov chaw yas yooj yim rau wrinkle; Tus thawj yuav tsum ua kom muaj kev nruj, thiab tus tom kawg yuav tsum txo qhov ceev ntawm txoj kab traction kom ntseeg tau tias lub sijhawm txias.
