PVC (Polyvinyl chloride) feem ntau plays lub luag hauj lwm ntawm rwb thaiv tsev thiab sheath nyob rau hauv lubkab, thiab cov nyhuv extrusion ntawm PVC hais ncaj qha cuam tshuam rau kev siv ntawm cov cable. Cov nram qab no teev rau 6 qhov teeb meem ntawm PVC particle extrusion, yooj yim tab sis siv tau heev!
01.PVC khoomhlawv tshwm sim thaum extrusion.
1. Cov ntsia hlau siv tau ntev, cov ntsia hlau tsis huv, thiab cov khoom siv hluav taws kub tau muab tshem tawm; Tshem cov ntsia hlau thiab ntxuav kom huv si.
2. Lub sij hawm cua sov yog ntev heev, PVC hais aging, scorch; Txo lub sijhawm cua sov, xyuas seb puas muaj teeb meem nrog lub tshuab cua sov, thiab kev saib xyuas raws sijhawm.
02. PVC hais tsis yog yas.
1. Qhov ntsuas kub tsawg dhau; Tsim nyog nce tuaj yeem ua tau.
2. Thaum granulating, cov yas sib tov tsis sib xws los yog muaj qhov nyuaj rau plasticize cov khoom hauv cov yas; Lub tes tsho pwm tuaj yeem ua kom zoo nrog cov me me, txhim kho lub siab ntawm cov kua nplaum lub qhov ncauj.
03. Extrude uneven thickness thiab slub puab
1. Vim yog cov ntsia hlau thiab traction instability, ua rau cov khoom tsis sib xws, vim yog cov teeb meem ntawm lub nplhaib nro, yooj yim los tsim xyoob, pwm yog me me, los yog cable core txoj kab uas hla hloov, ua rau thickness fluctuations.
2. Feem ntau xyuas cov traction, ntsia hlau, thiab nqa cov khoom nro los yog ceev, hloov raws sij hawm; Cov pwm sib txuam yuav tsum tsim nyog los tiv thaiv cov kua nplaum; Saib xyuas sab nraud txoj kab uas hla hloov tsis tu ncua.
04 ib.Cov khoom siv cableextrusion pores thiab npuas
1. Ua los ntawm lub zos ultra-siab kub tswj; Nws pom tias qhov kub thiab txias yuav tsum tau hloov kho raws sijhawm thiab tswj nruj heev.
2. Cov yas tshwm sim los ntawm kev ya raws lossis dej; Pom tau tias yuav tsum tau nres hauv lub sijhawm thiab net noo noo.
3. Lub tshuab ziab khaub ncaws yuav tsum tau ntxiv; Qhuav cov khoom ua ntej siv.
4. Cov tub ntxhais hlau yuav tsum tau preheated ua ntej yog tias nws ntub.
05. Cable khoom extrusion haum tsis zoo
1. Tsawg kub tswj, tsis zoo plasticization; nruj me ntsis tswj qhov kub thiab txias raws li tus txheej txheem.
2. Pwm hnav; Hloov kho lossis tshem tawm cov pwm pwm.
3. Tsawg lub taub hau kub, yas gluing tsis zoo; Tsim nyog tsa lub taub hau kub.
06. PVC hais extrusion nto tsis zoo
1. Cov resin uas nyuaj rau plasticize yog extruded yam tsis muaj plasticization, ua rau cov ntsiab lus me me thiab cov khoom siv rau ntawm qhov chaw, muab faib rau ntawm qhov chaw; Qhov kub thiab txias yuav tsum tau nce kom tsim nyog los yog cov kab khiav ceev thiab cov ntsia hlau ceev yuav tsum tau txo.
2. Thaum ntxiv cov khoom, impurities yog tov nrog rau saum npoo ntawm impurities; Thaum ntxiv cov khoom, impurities yuav tsum nruj me ntsis tiv thaiv los ntawm kev sib tov, thiab impurities yuav tsum tau ntxuav tam sim ntawd thiab cov ntsia hlau nco kua nplaum yuav tsum tau tshem tawm.
3. Thaum cov tub ntxhais cable hnyav dhau lawm, lub zog them nyiaj me me, thiab qhov cua txias tsis zoo, cov yas saum npoo yog yooj yim rau wrinkle; Tus qub yuav tsum ua kom qhov nro, thiab tom kawg yuav tsum txo cov kab traction ceev kom ntseeg tau lub sijhawm txias.
