Qhov sib txawv ntawm kev sib txawv ntawm lub tsev so xuab zeb thiab cov xuab zeb ntsuab xuab zeb dag nyob hauv hom xuab zeb lawv cov txheej txheem siv.
Resin xuab zeb tov khoom
Dab tsi yog Resin xuab zeb tov khoom?
Resin xuab zeb tov khoom yog lub tshuab tsim kom muab cov xuab zeb nrog cov khoom siv hluav taws xob thiab cov tshuaj catalenters (lossis cov khoom tawv) los tsim cov khoom siv muaj zog thiab ruaj khov rau cov txheej txheem casting. Nws ua kom cov khaub ncaws sib xyaw ntawm cov cob nrog cov xuab zeb los tsim cov khoom sib xws, cov khoom lag luam zoo lossis cores siv hauv hlau casting.
Cov yam ntxwv tseem ceeb ntawm lub resin xuab zeb tov khoom tov khoom
1.Sib tov sib xyaw:
Xoom: Feem ntau cov xuab zeb lossis cov xuab zeb tshwj xeeb haum rau casting.
Resin phau ntawv: tuaj yeem yog Phenolic, Furan, Epoxy, lossis lwm yam tshuaj lom neeg.
Catalyst / hardener: ntxiv rau pib pib siv tshuaj lom neeg thiab tawv tawv.
2.Tsim:
Nruam Mixers: tsim rau cov kab ntau lawm ntau lawm, uas cov xuab zeb thiab cov khoom siv txuas mus rau hauv cov tov khoom.
Batch Mixers: Txheej Txheem Xuab Zeb thiab Resin hauv kev tswj hwm ua ke rau qhov tseeb.
3.Nws cov txheej txheem sib xyaw:
Cov xuab zeb tau pub rau hauv cov tov khoom los ntawm kev cia siab.
Resin thiab catalyst yog metered thiab ntxiv rau cov xuab zeb nyob rau hauv cov lus qhia tshwj xeeb.
Cov sib tov yog sib xyaw nyob rau hauv ib lub chamber siv tig tuaj lossis paddles kom ntseeg tau tias cov txheej txheej ntawm cov xuab zeb hais.
4.Cov zis:
Cov kab sib xyaw ua ke yog tso tawm, npaj yuav ntim rau hauv cov pwm lossis cores.
Cov sib tov tawm sai sai vim muaj tshuaj lom neeg cov tshuaj tiv thaiv, ua cov pwm nruj.
Resin xuab zeb tov khoom thov
Resin xuab zeb tov khoom rau high-precision rau cov hlau zoo li hlau los yog aluminium uas yuav tsum tau nto qhov chaw du thiab cov ntsiab lus zoo.
Ntsuab Xaws Tov Khoom
Dab tsi yog ntsuab xuab zeb tov khoom?
Cov xuab zeb ntsuab xuab zeb yog lub tshuab siv los muab cov xuab zeb, dej, thiab av nplaum (feem ntau bentonite) rau hauv kev sib xyaw ua ke rau kev tsim cov pwm hauv cov txheej txheem casting txheej txheem. Lo lus "ntsuab xuab zeb" yog hais txog lub moist, pliable xwm ntawm cov xuab zeb sib tov, tsis yog nws xim. Cov xuab zeb ntsuab tau siv dav hauv cov khoom siv rau nws cov nyiaj tau, rov qab, thiab yooj yim ntawm kev tuav.
Cov yam ntxwv tseem ceeb ntawm cov xuab zeb ntsuab xuab zeb
1.Sib tov sib xyaw:
Xuab zeb: Silica xuab zeb yog cov siv cov khoom siv hluav taws xob ntau tshaj plaws.
Avy binder: bentonite av ua raws li tus neeg sawv cev ntawm txoj kev khi, muab cov xuab zeb rau nws lub zog thiab cov yas.
Dej: ya raws txuas ntxiv kom ua kom cov av nplaum thiab tsim cov khoom siv tsim nyog.
Yeem cov khoom sib ntxiv: cov ntaub ntawv ib yam li cov plua plav thee lossis lwm cov organic sib xyaw yuav suav nrog cov pwm lossis ua tiav.
2.Tsim:
Batch Mixers: Mix cov ntaub ntawv hauv me me, tswj cov khoom rau qhov tseeb.
Nruam mixers: cia li pub cov xuab zeb, av nplaum, thiab dej rau cov chaw siab ntau lawm.
Nruab nrog rotating paddles lossis li tuaj los ua kom meej txawm sib xyaw thiab tiv thaiv clumping.
3.Nws cov txheej txheem sib xyaw:
Cov xuab zeb nyoos, av nplaum, thiab dej ntxiv rau hauv tov.
Paddles lossis cov nplais tig mus rau tusyees faib cov khoom siv thiab ua tiav qhov xav tau.
Qhov sib xyaw kom sib tov raws li cov pliabed raws li lub pliable, cohesive loj, npaj txhij rau pwm-ua.
4.Cov zis:
Tau tsim cov xuab zeb ntsuab nrog lub zog kom yog thiab khi lub zog kom ua rau pwm.
Daim ntawv thov xuab zeb ntsuab
Ntsuab xuab zeb tov khoom rau hlau, thiab tsis-ferrous hlau castings, siv rau kev tsim cov pwm hauv cov hlau loj ntau lawm ntawm hlau casings.
