Plastics Extruders rau PA66 Thermal Break Strips | POLYWELL Solutions

Kev pab cuam tshuam ntawm dej ntxias yog qhov chaw nyob ze tshaj plaws hauv kev tsim kho ib qho khoom siv raw thermoplastic mus rau ib txoj hauv kev loj ntawm cov khoom finished loss semi-finished uas muaj ib qho chaw ntsug sib npaug, xws li profiles, pipes, sheets, thiab films. Qhov ceev tshaj plaws yog nrhiav plastic resin, tshaj tawm nrog rau daim duab pellet, los ntawm ib qhov rooj kom muaj dej ntxias hauv ib qhov khaub npag uas muaj ib lub screw uas rov. Lub screw no muaj peb qhov tseem ceeb: nws xa cov khoom siv zog mus sab laj, sau cov khoom siv nrog kev puag ncig thiab kev ruaj ua rau nws thawb yooj yim, tom qab ntawd nws muab cov thawb zoo ib yam nkaus nrog kev ruaj thiab ntau yam los ntawm ib qhov rooj kho. Qhov kev kho lub screw yog qhov tseem ceeb heev thiab tsim rau polymer tshwj xeej; piv txwv li, ib lub screw rau rigid PVC sib txawv ntau dua li ib lub uas tau raug kho rau glass-filled Polyamide 66 (PA66) vim muaj qhov sib txawv hauv melt viscosity, shear sensitivity, thiab thermal stability. Cov extruders tau raug chia tawm tshaj tawm los ntawm qhov kev sib txawv ntawm lub screw, uas muaj single-screw extruders yog tshaj tawm tshaj plaws vim nws tsim nyog thiab nyiaj ntau hauv cov lej xws li profile extrusion, thaum twin-screw extruders (co-rotating thiab counter-rotating) muaj kev pab zoo dua hauv kev mix, devolatilization, thiab output stability, uas tshuaj xyuas tseem ceeb rau compounding thiab processing heat-sensitive loss materials uas muaj khoom siv. Cov metrics tseem ceeb tshaj plaws rau ib lub extruder yog nws output rate (kg/hour), qhov siab ntawm kev sib npaug hnyav hluav taws xob, thiab kev siv hluav taws xob. Tom qab tawm los ntawm qhov rooj, lub extrudate yuav tsum tau sov, tshaj tawm nrog rau calibrated water bath loss nrog air knives, tom qab ntawd nws tau pull los ntawm haul-off unit ua ntej nws tau cut loss muab rov qab. Qhov kev nyab xeeb ntawm tag nrho qhov kev lag luam, los ntawm kev sib npaug ntawm cov khoom siv raw material feed mus rau qhov precision ntawm cov khoom downstream, qhia txog qhov txiaj ntsig ntawm cov khoom tiag tiag, uas pab lub plastics extruder zoo ib yam li ib qhov chaw siv khoom siv zoo tshaj plaws thiab tseem ceeb hauv kev tsim kho polymer hauv cheeb tsam no.
