1. Ua ntej pib lub tshuab, nws yog ib qho tsim nyog yuav tsum xyuas seb lub hwj chim ntawm lub tshuab hmoov puas yog raws li lub hwj chim ntawm lub qhov (socket) extruder.Tsuas yog tom qab lees paub tias tsis muaj qhov yuam kev tuaj yeem txuas lub zog hluav taws xob.
2. Tom qab cov hmoov feeder yog powered, tam sim ntawd soj ntsuam lub rotating system thiab cua sov system.Tom qab paub meej tias tsis muaj qhov yuam kev, tig lub tshuab hluav taws xob cua sov thiab ziab cov hmoov talc ntawm qhov kub ntawm 150 ℃ (ua tiav 1.5 teev ua ntej extrusion).30 feeb ua ntej ntau lawm, txo qhov kub thiab txias rau qhov ntau ntawm 60 + 20 / -10 ℃ ntawm qhov kub thiab txias rau kev siv
3. Npaj kom txaus talcum hmoov ua ntej ntau lawm.Tus nqi ntawm talcum hmoov yuav tsum yog 70% -90% ntawm lub peev xwm ntawm cov hmoov hla lub tshuab.Thaum lub sij hawm tsim khoom, xyuas seb cov talcum hmoov puas txaus tsawg kawg ib zaug ib teev, thiab ntxiv nws tam sim yog tias tsis txaus.
4. Thaum lub sij hawm tsim khoom, nws yog ib qho tseem ceeb kom ntseeg tau tias cov hlau hla mus rau nruab nrab ntawm txhua qhov kev qhia log ntawm cov hmoov feeder kom tsis txhob muaj cov hlau tsis zoo los ntawm cov khoom ua tiav los ntawm kev sib tsoo.
5. Kev xaiv ntawm extruded puab pwm rau hmoov coated hlau: Loj nws los ntawm 0.05-0.2M / M raws li tus qauv ib txwm (raws li cov hmoov txheej yuav nyob ntawm ib qho kev sib txawv, thiab cov pwm me me tuaj yeem ua rau cov tsos tsis zoo thiab cov hlau tawg yooj yim)
1. Kev tshem tawm tsis zoo:
ib.Cov hmoov me me dhau lawm, talcum hmoov tsis qhuav tag, thiab ib qho txaus ntawm cov hmoov qhuav talcum yuav tsum tau ntxiv.
b.Yog tias qhov kev ncua deb ntawm cov pwm sab hauv thiab sab nrauv yog qhov deb dhau thiab qhov protrusion yog qhov loj heev, nws yuav tsum tau txo qhov kev ncua deb ntawm cov pwm sab hauv thiab sab nrauv.
n.Sab nraud txoj kab uas hla ntawm cov khoom semi-tiav lawm stranding yog me me heev kom yooj yim hmoov: stranding thiab extrusion yog kho nrog ib tug tsim nyog tus nqi ntawm tso tawm neeg sawv cev ua ntej yuav hmoov
2. Cov tsos mob tshwm sim los ntawm cov hmoov ntau dhau:
ib.talcum hmoov accumulates ntau dhau rau hauv cov pwm puab duct, cuam tshuam kev ua haujlwm du ntawm cov khoom tiav thiab ua rau tsis zoo.Nws yog ib qho tsim nyog yuav tsum tau siv rab phom cua los tshuab ziab cov hmoov talcum hauv cov pwm sab hauv
b.Thaum txhuam tsis tau txhuam cov hmoov talcum ntau dhau, cov khoom lag luam ib nrab yuav tsum muab tso rau hauv nruab nrab ntawm cov txhuam hniav kom cov txhuam hniav tuaj yeem tshem tawm cov hmoov talcum ntau dhau.
c.Cov pwm sab hauv me me dhau lawm: Vim tias kev siv loj dua ntawm cov hmoov hlau sab hauv pwm piv rau cov hmoov hlau (ntawm tib lub ntsiab lus), nws yog ib qho yooj yim los xaiv ib qho pwm sab hauv nrog qhov pore loj 0.05-0.2M / M loj dua. ib txwm thaum lub sijhawm tsim khoom
3. Core hlau adhesion:
ib.Kev ua kom txias tsis txaus: Cov txheej txheej txheej ntawm cov hmoov kab feem ntau yog tuab, thiab vim tias tsis muaj cua txias thaum lub sij hawm tsim khoom, nws yooj yim ua rau cov tub ntxhais hlau adhesion.Thaum lub sijhawm tsim khoom, txhua ntu ntawm lub tank dej yuav tsum muaj cov dej txias txaus kom ua tiav qhov txias txaus
b.Insulated PVC melts ntawm qhov kub thiab txias, ua rau cov tub ntxhais hlau adhesion: cov tub ntxhais hlau yog extruded, thiab ib tug tsim nyog tus nqi ntawm tus neeg sawv cev tso tawm yog siv thaum lub sij hawm stranding.Ua ntej extruded, tus neeg sawv cev tso tawm yog siv ua ntej ua hmoov, los yog thaum raug extruded, lub stranding yog txhim kho los ntawm kev ua hmoov.
