Dab tsi yog Cov Txheej Txheem Ntau Lawm Thiab Cov Txheej Txheem Txheej Txheem Txheej Txheem Ntawm Cov Khoom Roj Hmab?
Jan 15, 2022
Muaj ntau ntau yam khoom siv roj hmab, tab sis cov txheej txheem tsim khoom yog tib yam. Cov txheej txheem tseem ceeb ntawm cov khoom siv roj hmab nrog cov khoom siv roj hmab-raws li cov khoom siv raw khoom suav nrog rau cov txheej txheem yooj yim: plasticizing, sib tov, calendering, extrusion, molding thiab vulcanization. Tau kawg, cov txheej txheem yooj yim xws li kev npaj cov khoom siv raw, cov khoom tiav tiav, kev tshuaj xyuas thiab ntim khoom kuj tseem ceeb. Kev siv thev naus laus zis ntawm roj hmab yog tsuas yog los daws qhov tsis sib xws ntawm plasticity thiab elasticity.
Los ntawm ntau txoj kev siv tshuab, cov roj hmab elastic tau hloov mus rau hauv cov yas masticated roj hmab, thiab tom qab ntawd ntau cov tshuaj sib xyaw ua ke tau ntxiv los ua cov khoom tiav, thiab tom qab ntawd cov khoom lag luam semi-tiav tau hloov mus rau hauv cov khoom siv roj hmab uas muaj elasticity thiab zoo lub cev thiab txhua yam. Cov khoom siv los ntawm vulcanization. Cov khoom siv roj hmab xa mus rau kev ua haujlwm ntawm kev tsim ntau yam khoom siv roj hmab nrog cov roj hmab ntuj thiab hluavtaws ua cov khoom siv raw, thiab tseem suav nrog cov khoom siv roj hmab uas tsim los ntawm cov roj hmab pov tseg. Cov zis ntawm cov roj hmab hluavtaws tau zoo heev tshaj li ntawm cov roj hmab ntuj, ntawm cov roj hmab styrene-butadiene yog qhov loj tshaj plaws.
