Barium sulfate uas tau muab tsoo yog li cov khoom siv tshuaj ntsuab thiab tsis muaj qhov tshuaj ntsuab, tsis zoo li cov khoom siv tshuaj ntsuab barite uas tau ua los ntawm kev txiav cov khoob thiab tsis muaj kev ua kom zoo. Lub tsev ntau tus neeg siv khoom siv thiaj li txhawj xeeb rau cov khoom siv ob qhov no, tab sis cov khoom siv barium sulfate uas peb ua los yog ua los ntawm cov khoob uas peb xaiv thiab kev ua kom zoo ntawm kev ua khoom siv thiab kev ua kom zoo, uas muaj qhov ntsuab zoo dua, qhov ntsuab nyuaj dua thiab qhov ntsuab zoo dua. Cov khoom siv no tau ua los ntawm cov khoob barium uas muaj kev pab cuam rau lub ntiaj teb, thiab tau ua los ntawm kev ua khoom siv uas tsis muaj kev pheej yig rau lub ntiaj teb, kev ua kom zoo ntau qhov thiab kev ua kom zoo ntawm kev ua khoom siv. Nws muaj qhov ntsuab tsis muaj khoom siv tsis zoo, qhov ntsuab zoo dua, qhov ntsuab zoo dua thiab qhov ntsuab zoo dua. Txhua qhov khoob uas peb ua khoom siv yog muaj kev txheeb xyuas, thiab txhua qhov kev ua khoom siv tau ua raws li cov kev cai ntawm lub ntiaj teb rau kev pab cuam rau lub ntiaj teb. Nrog kev txheeb xyuas ntau qhov thiab qhov ntsuab zoo dua, cov khoom siv barium sulfate uas peb ua los yog muaj kev nyiam rau kev siv ntau qhov thiab kev siv ntau qhov rau cov neeg siv khoom siv hauv lub ntiaj teb.
Daim ntawv pov tseg uas yuav tau rau cov barium sulfate uas tau ua los ntawm kev pov tseg yog cov ntawv pov tseg barite zoo tshaj plaws los ntawm cov chaw pov tseg uas tau muab xaiv. Peb xaiv cov ntawv pov tseg barite zoo tshaj plaws uas muaj qhov ntau ntawm barium sulfate, qhov me ntsis ntawm cov heavy metal, thiab qhov me ntsis ntawm cov khoob tshuaj tsis zoo uas nyob hauv ntawv pov tseg rau ua lub thawv rau kev ua noj. Thaum peb txhawj xyuas rau cov ntawv pov tseg barite me ntsis uas nyob hauv tsev kawm, cov ntawv pov tseg uas peb xaiv muaj qhov zoo tshaj plaws ntawm cov khoob tshuaj, qhov me ntsis ntawm cov dej ntawm khoob tshuaj, cov quartz, thiab cov khoob tshuaj tsis zoo uas tuaj yeem siv tau, uas pab tso cai rau cov khoom siv uas muaj qhov ntau ntawm cov dej ntawm khoob tshuaj thiab qhov zoo tshaj plaws ntawm cov khoob tshuaj. Peb muaj cov chaw pov tseg uas peb sib tham nrog lawm ntev, uas pab tso cai rau kev muab cov ntawv pov tseg los ntawm kev sib tham, qhov zoo tshaj plaws ntawm cov ntawv pov tseg, thiab qhov ntau ntawm cov ntawv pov tseg. Peb tsis xav siv cov ntawv pov tseg tsis zoo thiab cov ntawv pov tseg uas tau siv lawm los ua cov khoom siv rau kev ua noj, yog li cov khoom siv uas peb ua tau tsis yuav muaj qhov ntau ntawm cov dej ntawm khoob tshuaj, tsis yuav muaj cov dej ntawm khoob tshuaj, thiab tsis yuav pab tso cov khoom siv rau kev ua noj.
Tom qab uas peb tau cov khoom tawm ntawm lub vaj tswv, peb ua kev tshem tawm ntau yam thaum kawg rau hauv qhov kev sib txuas ntau yam. Cov khoom tawm ntawm lub vaj tswv thiab cov khoom tawm ntawm lub vaj tswv yuav tsum tau sau, txuas, thiab tshem tawm rau kom tshem cov dej, cov ntawv, thiab cov khoom tawm ntawm lub vaj tswv. Tom qab ntawd, cov khoom tawm ntawm lub vaj tswv uas tau tshem tawm yuav sib txuas nrog cov khoom siv hauv kev sib txuas thiab cov khoom siv hauv kev sib txuas rau hauv qhov chaw uas muaj qhov ceev zoo ib yam rau kom tau cov khoom tawm ntawm lub vaj tswv. Qhov kev sib txuas no siv qhov kev sib txuas ntau yam, uas tsis pub cov khoom siv hauv kev sib txuas ntau yam uas yuav tshem tawm cov khoom tawm ntawm lub vaj tswv. Ntawm qhov kev sib txuas ntau yam, peb tuaj yeem npaj cov khoom tawm ntawm lub vaj tswv rau cov khoom tawm ntawm lub vaj tswv, cov khoom tawm ntawm lub vaj tswv, thiab cov khoom tawm ntawm lub vaj tswv. Txhua yam kev sib txuas yuav tsum tau sau rau hauv qhov kev tshem tawm.
Kev puas tsuaj ntau thiab kev tshem tawm ntau yuav yog cov qhov ceev uas txhais qhov precipitated barium sulfate zoo li cas los ntawm cov khoom sib txawv. Cov lus hauv qab no yog qhov intermediate solution uas muaj peb lub tswv yim, thiab nws yog qhov sulfur-containing solution uas tau tshem tawm, thiab nws yog qhov kev puas tsuaj neutral puas tsuaj rau hauv cov tank puas tsuaj uas muaj cov kab tshuab. Qhov puas tsuaj ntawd yog qhov uas ua rau muaj cov crystal slurry hydrated barium sulfate. Qhov puas tsuaj thiaj li ua hauv cov khoom uas muaj cov kab tshuab kom tsis muaj dej lossis dust los ntawm qhov xwb. Tom qab ntawd, cov crystal slurry yuav mus rau hauv kev tshem tawm 4 zaug ntawm kev tshem tawm nrog kev tshem tawm nrog dej kom tshem tawm cov soluble salt ions, cov alkalis tsis tau tshem tawm, thiab cov chemical residues. Kev tshem tawm nrog dej ntau yuav pab txo qhov conductivity ntawm cov powder, pab nce qhov weather resistance ntawm cov khoom, thiab pab tshem tawm qhov paint film bubbling, plastic aging, thiab rubber performance decline uas muaj los ntawm cov impurities tsis tau tshem tawm. Qhov kev tshem tawm ntau ntawd yog qhov yuav tsum muaj ntawm peb cov khoom los ntawm cov crude precipitated powder uas muaj nqi ntau.
Kab mob txhais rau qhov kawg, kab mob tshuaj, thiab kab mob txhais rau qhov kawg txhais rau qhov sib sau ntawm cov khoom siv. Tom qab muab cov khoom tsis zoo tshem tawm thiab muab txhais rau, cov khoom siv barium sulfate uas muaj qhov zoo yuav tau muab tuaj rau cov khoom siv tshuaj tshuaj uas muaj kev sib xyaw ntau. Kab mob tshuaj tshuaj yuav tsis ua rau qhov cim ntawm cov khoom siv hauv qhov cim, yog li cov khoom siv yuav muaj qhov zoo thiab muaj kev sib xyaw zoo. Tom qab ntawd cov khoom siv uas tau tshuaj yuav tau muab tshuaj tshuaj ntau thiab muab txhais rau los ntawm cov khoom siv tshuaj tshuaj uas muaj kev sib xyaw ntau, uas yuav txhais rau cov khoom siv rau qhov sib sau ntawm cov khoom siv rau cov kev sib xyaw ntawm cov khoom siv. Peb tsis muab cov khoom siv uas muaj kev sib xyaw, cov khoom siv uas muaj kev sib xyaw, thiab cov khoom siv uas muaj kev sib xyaw rau cov khoom siv, yog li cov khoom siv yuav muaj qhov zoo thiab tsis muaj kev sib xyaw. Ntawd kuj, peb muab cov khoom siv rau hauv cov khoom siv uas muaj kev sib xyaw rau qhov sib xyaw thiab rau qhov sib xyaw rau qhov sib xyaw thiab rau qhov sib xyaw rau qhov sib xyaw.
Kev tswj hwm cov khoom zoo tshaj plaws yuav pab rau kev tswj hwm cov khoom zoo. Los ntawm kev ntaus cov khoom tshiab mus rau kev xa cov khoom finished, cov neeg nyob rau hauv cov laboratori yuav txhais cov khoom zoo los ntawm kev txhais cov khoom muaj li cas, cov kab mob, cov dej, cov khoom tsis zoo, thiab cov khoom tsis muaj kev cuam tshuam nrog lwm yam khoom. Cov khoom tsis zoo yuav tsum rov qab mus ua dua raws li kev tswj hwm. Thaum peb sib piv rau cov barite uas tau ntaus, peb cov synthetic precipitated barium sulfate muaj kev sib sod zoo dua rau cov resin thiab pigment, muaj kev tshem tawm ntawm cov khoom siv ntau dua, thiab muaj kev zoo dua rau cov khoom. Vim tias peb muaj cov khoom tshiab zoo, cov kev ua haujlwm tshem tawm zoo, thiab kev tswj hwm cov khoom zoo, cov khoom ntawv muaj kev sib txawv ntawm cov khoom tshiab thiab khoom kawg zoo ib yam, muaj kev ua haujlwm zoo rau lub siab thiab muaj nqi zoo. Nws yog tus phoojyeej uas muaj kev nyab xeeb rau kev siv cov khoom sib txuas ntxiv rau cov neeg siv khoom hauv lub ntiaj teb.
