PVC Extruder rau kev tsim hluas plastik | POLYWELL Solutions

Qhov cuam tshuam PVC yog qhov cuam tshuam polymer tsim nyog rau kev pab thaum siv Polyvinyl Chloride, ib qho thermoplastic siv ntau thiab muaj peev xwm, tab sis kuj muaj kev nyuaj siab txog kub thiab shear. PVC tuaj yeem tsim los ntawm rigid (uPVC) lossis zoo phem, nrog cov plasticizers tau ntxig, thiab txhua qhov tsim yuav tsum tau kev cuam tshuam tshwj xeej. Qhov teeb meem tseem ceeb tshaj plaws hauv kev cuam tshuam PVC yog qhov kub deb ntawm khoom, uas txhawj xeeb kom tsis pub tso gas hydrochloric acid tawm. Yog li, cov screw rau PVC tau tsim nrog qhov ntev hauv qhov chaw muab khoom thiab compression ratio tsuas li 2:1 mus rau 2.5:1, kom sau nqaij kev kub los ntawm shear. Cov cuam tshuam twin-screw, tshpecially cov counter-rotating parallel lossis conical, yog standard hauv vaj tse ua rigid PVC profile extrusion. Lawv cov kev pab cuam tshuam zoo dua thiab kev sib txuas kub zoo dua, tsim kev kho kom zoo, shear kub tsuas li, thiab tuaj yeem pab cuam tshuam cov powder blends tsis tas yuav compounding ua ntej. Kev kho kub hauv barrel tau kho kom meej, feem ntau nyob rau sab laug hauv qhov chaw xa khoom thiab rov cuag nce. Tom qab no, qhov profile uas tau cuam tshuam mus rau hauv qhov calibration thiab cooling system kom muaj qhov loj meej, vim PVC muaj qhov shrinkage factor zoo. Vim tias cov khoom siv PVC muaj qhov corrosive, cov ntsiab lus tseem ceeb zoo li screw thiab barrel tuaj yeem tsim los ntawm cov khoom uas tsis corrode. Qhov siv ntau ntawm PVC hauv cov khoom siv rau tsev, zoo li window profiles, pipes, thiab sidings, ua rau qhov cuam tshuam PVC tau tsim zoo heev thiab yog ib qhov tseem ceeb hauv kev tsim khoom plastics.
