1.Raw Khoom Npaj:Cov khoom siv los ua PVC granules yog PVC resin, plasticizers, stabilizers, lubricants, thiab lwm yam additives.Cov ntaub ntawv no tau ua tib zoo ntsuas thiab npaj raws li qhov xav tau formulation raws li cov neeg siv khoom xav tau.
2.Kev sib xyaw:Cov ntaub ntawv raw yog sib xyaw rau hauv cov khoom siv ceev ceev kom ntseeg tau tias muaj kev sib xyaw ua ke.Cov txheej txheem sib xyaw feem ntau suav nrog kev sib xyaw qhuav thiab cua sov kom ua tiav qhov sib xyaw ua ke.
3.Kev sib xyaw ua ke:Tom qab ntawd cov khoom sib xyaw ua ke yog muab tso rau hauv extruder, qhov chaw uas lawv melted thiab compounded.Lub extruder heats qhov sib tov mus rau qhov kub thiab txias, ua rau cov PVC resin yaj thiab cov additives los sib tov kom huv si.Cov kauj ruam no yog qhov tseem ceeb rau kev ua tiav cov khoom xav tau ntawm cov khoom kawg.
4.Extrusion:Cov molten PVC sib tov yog yuam los ntawm ib tug tuag los ua nruam strands los yog nplooj ntawv.Cov duab ntawm qhov tuag txiav txim siab cov duab ntawm cov khoom extruded.
5.Cua txias:Cov extruded PVC strands los yog nplooj ntawv yog txias sai heev, feem ntau yog nyob rau hauv ib da dej da dej, kom solidify lawv.Cov kauj ruam ua kom txias no pab tswj cov duab thiab kev ncaj ncees ntawm cov khoom.
6.Pelletizing:Cov khoom siv PVC txias yog ces txiav mus rau hauv me me granules los yog pellets.Qhov no tuaj yeem ua tiav siv ntau yam khoom siv pelletizing, xws li strand pelletizers lossis tuag-face pelletizers.
7.Kev tshuaj ntsuam thiab kev faib tawm:Cov PVC granules raug tshuaj xyuas kom tshem tawm cov khoom loj lossis qhov tsis zoo.Cov kauj ruam no xyuas kom meej tias cov granules yog sib xws ntawm qhov loj thiab cov duab.
8.Ntim:Qhov kawg PVC granules tau qhuav thiab tom qab ntawd ntim rau hauv hnab, ntim, lossis ntim khoom ntim rau kev faib khoom thiab muag.
9.Kev Tswj Xyuas Zoo:Thoob plaws hauv cov txheej txheem tsim khoom, kev tswj xyuas kev ua tau zoo yog siv los xyuas kom meej tias PVC granules ua tau raws li qhov yuav tsum tau ua.Qhov no suav nrog kev sim rau lub cev lub cev, tshuaj lom neeg muaj pes tsawg leeg, thiab lwm yam cuam tshuam.
