Lub tshuab tseem ceeb ntawm PVC hose tshuab muaj xws li plasticizing thiab mixing PVC resin thiab additives siv ib tug ntxaib - ntsia hlau extruder, extruding lub preform los ntawm ib tug tuag, thiab ces txias, shaping, kos duab, thiab txiav kom tiav cov txheej txheem ntau lawm.
Cov txheej txheem tseem ceeb ntawm PVC hose tshuab yog nyob rau hauv cov txheej txheem extrusion molding. Cov txheej txheem no siv cov kev sib hloov ntawm cov ntsia hlau thiab cov cua sov kom sov cov khoom siv PVC rau lub xeev molten hauv lub thoob. Lub molten PVC yog ces extruded los ntawm cov tuag nyob rau hauv lub taub hau tuag los tsim ib tug nruam tubular khoom. Thaum lub sij hawm extrusion, lub tshuab ua kom txias sai sai ua rau lub tshuab extruded los txhim kho nws cov duab thiab txhim kho nws lub cev.
