Nrog rau kev loj hlob sai ntawm cov tshuab kev lag luam, kev lag luam casting tsim sai heev, nrog rau kev siv cov khoom siv xuab zeb coated yog nce, feem ntau vim tias cov khoom siv xuab zeb coated npog thaj tsam me me, kev ua haujlwm yooj yim thiab kev nqis peev tsawg. Txoj kev loj hlob yav tom ntej ntawm cov xuab zeb coated yog: txo kev ua qias tuaj ib puag ncig, txhim kho kev tsim dua tshiab, txhim kho kev txawj ntse; Hloov cov khoom rheological ntawm phenolic resin, thiab txhim kho cov tshuaj tiv thaiv, enchantment thiab curing zog ntawm resin; Txo qhov kub thiab txias ntawm cov xuab zeb coated, txo lub sijhawm kho, uas tuaj yeem tsis tsuas yog txo lub zog noj, txhim kho kev ua tau zoo; Txhim kho lub peev xwm rov ua dua tshiab ntawm cov khoom siv xuab zeb coated thiab txo cov nqi tsim khoom lag luam.
Hauv kev lag luam casting, coated xuab zeb yog ib qho khoom siv tsis tau. Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam casting, qhov kev thov rau cov xuab zeb coated yog nce. Txhawm rau txo cov nqi tsim khoom thiab txo cov pa phem rau ib puag ncig, nws yog ib qho tseem ceeb heev uas yuav tsum ua txoj haujlwm zoo hauv kev siv cov xuab zeb thib ob. Kev rov tsim dua tshiab ntawm cov xuab zeb qub ntawm cov xuab zeb mulched tsis tsuas yog txuag lub zog, tab sis kuj txo cov pa phem ib puag ncig thiab txo qhov kev ntxhov siab ib puag ncig. Yog li dab tsi yog qhov txawv ntawm qhov qub xuab zeb rov qab thiab rov tsim dua tshiab ntawm cov khoom siv xuab zeb coated uas peb feem ntau hais?
Kev rov ua dua ntawm cov xuab zeb siv feem ntau txhais tau tias crushing cov clumps hauv cov xuab zeb siv los tshem tawm cov impurities thiab residues. Cov txheej txheem tseem ceeb yog cov xuab zeb qub los ntawm kev sib tsoo, sib nqus sib nqus, kev tshuaj xyuas thiab kev tshem tawm plua plav. Tom qab cov txheej txheem ntawm lub cev, cov binder zaj duab xis nyob rau saum npoo ntawm cov xuab zeb tsis raug tshem tawm, yog li cov xuab zeb qub tau siv dua, thiab cov xuab zeb nrog kev huv huv dua tsuas yog tau, uas txawv ntawm cov xuab zeb tshiab thiab tsis tuaj yeem hloov daim ntawv thov ntawm cov tshiab. xuab zeb. Tom qab ntxiv ntau hom xuab zeb no, nws yuav ua rau muaj teeb meem xws li qhov nce ntawm qhov tsis xws luag, yog li nws yuav tsum tau tswj hwm raws li qhov sib npaug lossis siv cov xuab zeb rov qab.
Cov xuab zeb qub qub feem ntau yog siv rau lub cev, tshuaj thiab thermal kho ntawm cov xuab zeb qub. Ntxiv nrog rau cov yeeb yaj kiab lossis lub plhaub ntawm cov av nplaum los yog cov residue residue accumulated nyob rau hauv cov xuab zeb, muaj teeb meem hais thiab plua plav, thiaj li hais tias nws tsim cov thawj particle loj tis dua. Cov yam ntxwv ntawm cov xuab zeb qub tom qab rov tsim dua yog ze rau cov xuab zeb tshiab, thiab cov khoom siv tau zoo xws li lub cev, tshuaj lom neeg thiab refractoriness tsis txawv heev. Qhov Performance index yog ze rau cov xuab zeb qub thiab tuaj yeem sib xyaw nrog cov xuab zeb qub hauv ib qho loj. Qhov kev thov rau saum npoo zoo tsis yog siab heev. Nws tuaj yeem siv ncaj qha rau ntawm lub ntsej muag xuab zeb.
