Flat ntxaib ntsia hlau chim ua lub luag haujlwm tseem ceeb hauv kev tsim cov kav dej PVC thiab cov profiles.Nws daim ntawv thov nyob rau hauv ob daim teb no tau teev tseg hauv qab no: Plasticization thiab kev sib xyaw ntawm cov ntaub ntawv: Cov ntsia hlau chim siab melts thiab mixes PVC resin thiab lwm yam additives los ntawm lub rotating ntsia hlau thiab cua sov cheeb tsam.Qhov no ua rau cov khoom siv PVC mos thiab yooj yim rau kev ua thiab cov duab.Extrusion molding: Nyob rau hauv qhov kev txiav txim ntawm cov ntsia hlau chim, cov khoom siv PVC molten yog extruded los ntawm cov tuag los ua ib tug tubular los yog profile-shaped khoom.
Kev tsim thiab kev hloov kho ntawm lub taub hau ntsia hlau ua rau kev tsim cov kav dej thiab cov profiles ntawm cov duab sib txawv thiab ntau thiab tsawg.Txias thiab solidification: Tom qab extrusion, cov yeeb nkab lossis qhov profile tau txias txias los ntawm cov cua txias kom khov cov khoom thiab tswj nws cov duab.Txiav thiab Trimming: Siv cov cuab yeej xws li cov tshuab txiav thiab txiav cov cav tov los kho qhov loj thiab ua kom tiav cov txheej txheem ntawm extruded kav thiab profiles.Nyob rau hauv luv luv, lub tiaj tus ntxaib-ntsia hlau chim chim plays lub luag hauj lwm tseem ceeb nyob rau hauv cov txheej txheem ntawm zus tau tej cov PVC kav thiab profiles, realizing lub plasticization, sib tov, extrusion molding thiab tom qab ua tiav ntawm cov ntaub ntawv, xyuas kom meej qhov zoo thiab kev ua tau zoo ntawm cov khoom kawg.
