Txheej Txheej Txheej Txheej Txheem Rau Precision Casting.

Lub cev thiab tshuaj tsis haum ntawm silica sol feem ntau suav nrog: SIO2 cov ntsiab lus, qhov ntom ntom, Na2o cov ntsiab lus, PH nqi, kinematic viscosity, colloidal particle txoj kab uas hla, thiab lwm yam. Cov kev ntsuas lub cev thiab tshuaj lom neeg no feem ntau cuam tshuam rau lub zog ntawm lub plhaub, kev ruaj ntseg ntawm txheej thiab hmoov-rau-kua piv ntawm txheej.

Txij li thaum nws yog ib qho nyuaj rau precision casting tuam txhab los ntsuam xyuas cov tsis muaj lub cev thiab tshuaj, ntawm ib sab, nws yog tsim nyog los ntxiv dag zog rau kev xaiv, kev ntsuam xyuas thiab kev pom zoo ntawm lwm tus neeg; Ntawm qhov tod tes, txheej txheej saum npoo thiab sab nraub qaum yuav tsum siv cov khoom sib txawv ntawm silica sol. Xaiv S-830 silica sol, thiab xaiv S-1430 silica sol rau txheej rov qab. Txoj kev npaj ntawm cov txheej txheem yuav cuam tshuam ncaj qha rau qhov zoo ntawm castings hauv precision casting, yog li cia peb nkag siab txog qhov kev npaj ntawm txheej txheej.

Hauv kev npaj cov txheej txheem, silica sol feem ntau yog ntxiv ua ntej, tom qab ntawd tus neeg sawv cev ntub dej ntxiv, thiab cov hmoov refractory ntxiv thaum nplawm, thiab thaum kawg defoaming tus neeg sawv cev ntxiv. Txhawm rau kom ntseeg tau tias cov txheej txheem zoo, thaum tag nrho cov txheej txheej saum npoo yog cov ntaub ntawv tshiab, lub sijhawm sib xyaw yuav tsum ntev dua 24 teev. Yog tias qee yam ntawm lawv yog cov khoom siv tshiab, lub sijhawm nplawm tuaj yeem ua kom luv rau 12 teev. Lub sijhawm nplawm ntawm cov txheej txheem hloov pauv thiab rov qab txheej txheej tuaj yeem tsawg dua li ntawm cov txheej txheej saum npoo. Thaum tag nrho cov xim yog tshiab, lub sij hawm stirring yog ntau tshaj 10h, thiab thaum ib co tshiab, lub sij hawm stirring yuav luv luv los ntawm ib nrab. Yog tias cov xim npaj tsis siv, nws yuav tsum tau npog thiab kaw kom tsis txhob muaj dej evaporation.

Nws yog qhov zoo tshaj plaws tsis txhob sib tov xim hauv lub plhaub ua haujlwm, tab sis teeb tsa cov khoom siv xim tshwj xeeb.
