Hauv peb lub neej tam sim no, feem ntau hais lus, cov tshuab yas extrusion thiab khoom siv uas kuv cov phooj ywg feem ntau tham txog yog cov yas extruder, uas yog qhov tseem ceeb rau kev tsim khoom ntawm ntau yam khoom. Dab tsi yog kev siv cov yas extruder?
Feem ntau hais lus, kev siv cov yas extruder yog extrusion granulation thiab extrusion molding.
Nyob rau hauv lub neej tam sim no, feem ntau cov khoom yas yog tsim los ntawm extrusion ntawm cov khoom yas. Yog li ntawd, lub granulation muaj nuj nqi ntawm yas extruder yog heev ntau. Lub extruder rau extruding hais kuj hu ua yas granulator. Cov yas yog sib xyaw nrog qee cov yas ntim thiab rov ua dua tshiab thiab cov hmoov qub qub los ntawm kev faib ua feem ntawm cov mis los ntawm kneader. Nws yog tag nrho tov los ntawm kneading tshuab, thiab ces nws yuav muab tso rau hauv lub yas granulator rau extrusion. Cov khoom extruded los ntawm yas raw cov ntaub ntawv los ntawm cov yas granulator yog ntau cylindrical strips, uas yog txias los ntawm dej txias thiab ces txiav mus rau hauv me me hais los ntawm granulator, uas yog cov hais peb xav tau.
Cov khoom yas ntawm cov txheej txheem extrusion feem ntau yog extruded ncaj qha los ntawm cov khoom yas, thiab tom qab ntawd dej-txias kom tau cov khoom peb xav tau. Kuj tseem muaj qee qhov kev txhaj tshuaj molding thiab tshuab molding khoom, qee qhov yuav raug extruded los ntawm kev txhaj tshuaj yas raw khoom los ntawm cov yas extruder. Yog li ntawd, yas extruders yog dav siv.
