Cov txheej txheem ntau lawm ntawm pvc hose tsuas yog suav nrog cov kauj ruam hauv qab no:
Cov khoom lag luam raw ua: Ua ntej, raws li cov khoom lag luam uas tsim nyog, yasizer thiab lwm yam khoom siv roj av, thiab txiav txim siab ntawm txhua feem. Ua kev soj ntsuam zoo ntawm cov ntaub ntawv raw ua kom ntseeg tau tias lawv tau raws li kev tsim khoom, thiab ua cov kev tsim khoom tsim nyog xws li ziab thiab sib tov.
Kneading: Tso PVC Resin, Yas Coolizer, Stabilizer, Roj Av thiab Lwm Cov Khoom Siv Raw rau hauv lub tshuab kneading hauv ib qho kev txiav txim. Cov kev txiav txim ib txwm ntawm kev pub mis yog PVC Resin, Planizer, Stabilizer, Roj nplua nyeem. Thaum lub sij hawm kneading, qhov ntsuas kub tau tswj hwm ntawm 100 ~ 110 lub sijhawm Celsius, thiab lub sijhawm Kneading Celsius, thiab lub sijhawm kneading
Granulation: Cov khoom siv kneaded yog granulated. Thaum lub sij hawm granulation yuav tsum tau them rau kom ntseeg tau tias cov khoom kub tsis tshaj qhov kub thiab txias tshaj qhov kub ntawm raj extrusion molding.
Extrusion Molding: Ntxiv cov khoom siv granuled rau tus extruder, thiab cov yas qhwv nws los ntawm lub thoob thiab ntsia hlau ntawm lub xeev homogeneous molten. Qhov kub tswj ntawm extruder ncaj qha cuam tshuam rau cov fellitity ntawm cov yaj thiab qhov zoo tshaj ntawm cov khoom extruded. Thaum lub sij hawm cov txheej txheem extrusion, ua tib zoo mloog rau cov tsos thiab viscrosity ntawm cov khoom siv moltive kom ntseeg tau tias qhov chaw ci thiab tsis muaj qhov tsis muaj pob txha. Cua txias thiab shaping: qhov kub ntawm lub hose tom qab extrusion tseem muaj siab heev thiab xav tau txias thiab zoo li tus. Rau cov hoses nrog me me diameters (tsawg dua 60mm), feem ntau yog tsis tas yuav tsum tau ua rau lub raj kom ntseeg tau qhov tseeb thiab kev ruaj ntseg ntawm lub raj diam. Txias dej tso tsheb hlau luam lossis dej txias tso tsheb hlau luam nrog tshuaj tsuag cov cuab yeej kuj tseem yog cov khoom siv cua txias. Traction thiab txiav: Thaum txias thiab ua kom txias, cov tractting, lub luag haujlwm ua rau lub taub hau extruder tsis tu ncua thiab txiav nws raws li qhov xav tau ntev. Lub Traction ceev feem ntau nrawm dua li qhov extrusion ceev los txhim kho lub pob tshab thiab ntev bumpture tsis kam ntawm cov hose. Curling thiab ntim: Tom qab cov kev nce qib tiav, cov hose yog curled thiab ntim, thiab thaum kawg kev kuaj xyuas yog nqa tawm. Lub tiav lawm pvc hose uas dhau qhov kev tshuaj xyuas zoo tuaj yeem muab tso rau ntawm kev ua lag luam muag.
Qhov txawv ntawm pvc hose thiab pvc hax yeeb nkab: pvc hose muaj ntau cov roj hmab thiab lwm yam kev sib ntxiv, tsis tuaj yeem tiv taus ntau dhau ntawm kev siv. PVC tawv tus yeeb nkab tsis muaj cov yas ua kom yooj yim, yog li nws yooj yim rau cov duab thiab muaj zog tiv taus.
