1: plasticizing
Los ntawm qhov kev txiav txim ntawm chim ntsuas kub thiab ntsia hlau, cov khoom hloov mus rau hauv homogeneous nruam yaj nrog ib qho muaj npliag.
Ob: molding tshuab
Vim lub ntws ntawm qhov tsis sib txig ntawm lub ntsej muag sib cais, cov ntsia hlau nkag mus rau lub taub hau tshuab los ntawm cov phaj perforated vim kev sib hloov ntawm cov ntsia hlau, thiab tau tsim rau hauv parison nrog qee yam qauv raws li cov tuag tub ntxhais qws.
Peb: Txias
Ntawd yog, nyob rau hauv cov nyhuv ntawm extrusion siab thiab traction, lub parison yog zoo li tus qauv los ntawm lub tshuab nqus tsev txias los ua ib yam khoom nrog qee lub zog, txhav thiab qhov tseeb raug.
2-4 cov txheej txheem granulation
Cov txheej txheem granulation yog cov txheej txheem ua haujlwm nyob rau hauv uas cov cob thiab ntau yam ntxiv tau suav, sib xyaw, thiab yas los ua cov ntawv cog lus me me, kheej kheej, thiab cov thawv uas yooj yim rau daim ntawv. Nws muaj ntau txoj hauv kev rau granulate, xws li:
Resin + Pabcuam → Qhov hnyav → Kev hnyav → sib tov → Extrusion → Round Bar → Cua Txias → Kab Pelletizer Pelletizer
Extrusion granulation kev ua haujlwm yog tas mus li, kaw, yooj yim los lim tawm impurities, siab tsim tawm, tsis tshua muaj zog ua haujlwm, huv ib puag ncig thiab suab nrov qis, tab sis qhov zoo ntawm plasticizing tsis yooj yim los tswj raws li cov qauv ntsiav tshuaj.
2-5 Tswj kev rho tawm txheej txheem
Cov txheej txheem txheej txheem kev tswj hwm suav nrog kev tswj cov tshuaj molding kub, extrusion ceev, nqus dehumidification, nqus nrawm, thiab lub tshuab nqus tsev txias.
1. Kev tswj qhov ntsuas kub
Extrusion qhov kub thiab txias yog qhov tsim nyog los txhawb kev hloov khoom yas ntawm cov khoom siv molding thiab kev ntws ntawm cov yas yaj. Nws ncaj qha cuam tshuam rau lub xeev qhov xwm txheej ntawm cov khoom siv thaum lub sij hawm ua tiav tag nrho cov txheej txheem. Nws yog ib qho tseem ceeb heev rau kev txiav tawm ntawm cov yas yas thiab cov khoom tsim thiab qhov zoo ntawm cov ntsiab lus Lub ntsiab lus.
Lub sijhawm ua tiav tag nrho cov txheej txheem, cov khoom yuav tsum ua tiav qhov hloov ntawm lub xeev iav rau siab elastic xeev mus rau khov dej ntws xeev, thiab kev tswj qhov kub thiab txias ntawm txhua ntu kuj sib txawv.
