Blister tshuab los tsim cov ntawv PVC hloov granulation

PVC feem ntau yuav tsum tau hloov kho thiab granulated ua ntej, thiab tom qab nws tau npaj rau hauv granules nrog ib tug ntsia hlau extruder, lub plasticization yog ntau txaus thiab kev ua tau yooj yim dua, tshwj xeeb tshaj yog rau cov khoom uas nws cov txheej txheem yog txhaj molding. Ntsia hlau extruder yog ib qho ntawm cov khoom siv tseem ceeb tshaj plaws rau kev ua cov yas molding. Nws nqa tawm cov khoom conveying, compaction, melting, shearing thiab extrusion molding ntawm plastics los ntawm sab nraud fais fab kis thiab tshav kub hloov los ntawm cov cua kub sab nraud. Cov ntsia hlau extruder plays lub luag haujlwm tseem ceeb ua lub tshuab yas thiab granulating lossis molding thiab ua tshuab. Hais lus nruj me ntsis, cov khoom siv PVC nrog cov kev cai tshwj xeeb thiab PVC hloov cov qauv tsim tau raws li cov neeg siv khoom xav tau. Kuj tseem muaj copolymerization derivatives hauv PVC txheej txheem. Xws li kev hloov kho ntau yam suav nrog vinyl chloride copolymer, polyvinyl chloride blends thiab chlorinated polyvinyl chloride.
