Blister ntim tshuab blister PVC hloov granulation

PVC feem ntau yuav tsum tau hloov kho thiab granulated ua ntej. Tom qab tau npaj rau hauv granules nrog cov ntsia hlau extruder, cov yas yog ntau txaus thiab kev ua tau yooj yim dua, tshwj xeeb tshaj yog rau cov khoom uas txhaj tshuaj molded. 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, compacting, melting, shearing, mixing 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 granulation lossis lub tshuab molding. Hais lus nruj me ntsis, cov khoom siv PVC nrog cov kev cai tshwj xeeb thiab PVC hloov cov mis yog tsim raws li cov neeg siv khoom xav tau. Kuj tseem muaj copolymerization derivatives hauv PVC txheej txheem. Cov kev hloov pauv zoo li no suav nrog vinyl chloride copolymer, polyvinyl chloride blends thiab chlorinated polyvinyl chloride.
