Cov iav clarifiers feem ntau yog siv cov khoom siv tshuaj lom neeg hauv cov iav ntau lawm. Txhua yam khoom siv raw uas tuaj yeem decompose (gasify) ntawm qhov kub thiab txias thaum lub sij hawm iav melting txheej txheem los tsim cov roj los yog txo cov viscosity ntawm cov kua iav los txhawb kev tshem tawm cov npuas hauv cov kua iav yog hu ua clarifier. Raws li cov txheej txheem ntawm iav clarification, nws tuaj yeem muab faib ua: oxide clarifier (feem ntau hu ua: oxygen clarification), sulfate clarifier (feem ntau hu ua: sulfur clarification), halide clarifier (feem ntau hu ua: halogen clarification) thiab composite clarifier ( feem ntau hu ua: Compound clarification).
1. Oxide clarifier
Oxide clarifiers feem ntau suav nrog dawb arsenic, antimony oxide, sodium nitrate, ammonium nitrate, thiab cerium oxide.
1. Dawb arsenic
Dawb arsenic, tseem hu ua arsenous anhydride, yog ib qho kev siv cov lus qhia meej nrog cov txiaj ntsig zoo heev. Nws yog feem ntau hu ua "Clarification King" hauv kev lag luam iav. Tab sis cov arsenic dawb yuav tsum tau siv ua ke nrog nitrate kom ua tiav cov txiaj ntsig zoo. Dawb arsenic yog me ntsis soluble hauv dej txias thiab yooj yim soluble hauv dej kub. Nws yog tshuaj lom heev. Nws yog dawb crystalline hmoov los yog ib qho amorphous iav. Raws li ib tug byproduct ntawm kub smelting, arsenic grey feem ntau yog grey, grey los yog grey-dub. Nws feem ntau yog siv los ua tus neeg saib xyuas kom meej. arsenic. Thaum cov arsenic dawb yog rhuab mus rau ntau tshaj 400 degrees, nws yuav tsim arsenic pentoxide nrog cov pa tawm los ntawm nitrate nyob rau hauv high kub. Thaum rhuab mus rau 1300 degrees, arsenic pentoxide yuav decompose los tsim arsenic trioxide, uas txo cov pa ib nrab siab ntawm cov pa hauv iav npuas. Nws yog qhov tsim nyog rau kev loj hlob ntawm npuas thiab ua kom nrawm ntawm kev tshem tawm npuas, thiaj li ua tiav lub hom phiaj ntawm kev nthuav dav.
Tus nqi ntawm cov arsenic dawb feem ntau yog 0.2% -0.6% ntawm cov nyiaj batch, thiab tus nqi ntawm nitrate qhia yog 4-8 npaug ntawm cov dawb arsenic. Kev siv ntau dhau ntawm cov arsenic dawb tsis tsuas yog ua rau cov volatilization, tab sis kuj ua rau ib puag ncig thiab ua rau muaj kev phom sij rau tib neeg lub cev. 0.06 grams dawb arsenic tuaj yeem ua rau tuag taus. Yog li ntawd, thaum siv cov arsenic dawb, ib tus neeg tshwj xeeb yuav tsum tau ua kom nws thiaj li tiv thaiv tau qhov xwm txheej lom. Cov iav nrog cov arsenic dawb li cov neeg ua kom pom tseeb yog ib qho yooj yim los txo thiab ua kom cov iav dub thaum lub sijhawm ua haujlwm ntawm lub teeb, yog li cov arsenic dawb yuav tsum tau siv tsawg dua los yog tsis nyob hauv lub teeb iav.
2. Antimony oxide
Cov nyhuv qhia meej ntawm antimony oxide zoo ib yam li cov arsenic dawb, thiab nws yuav tsum tau siv nrog nitrate. Qhov kev qhia meej thiab qhov decomposition kub ntawm kev siv antimony oxide yog qis dua li ntawm cov arsenic dawb, yog li antimony oxide feem ntau siv los ua ib qho kev qhia meej thaum melting iav. Hauv dej qab zib txiv qaub silicate iav, 0.2% antimony oxide thiab 0.4% dawb arsenic yog siv los ua cov neeg ua kom pom tseeb, uas muaj cov txiaj ntsig zoo dua thiab tuaj yeem tiv thaiv kev tsim cov npuas thib ob.
3. Nirate
Nitrate ib leeg tsis tshua siv los ua tus neeg saib xyuas kom meej hauv iav, thiab nws feem ntau yog siv los ua cov pa oxygen pub rau ua ke nrog cov valence oxides sib txawv.
4. Cerium dioxide
Cerium dioxide muaj qhov kub ntawm qhov decomposition ntau dua thiab yog qhov pom tseeb zoo dua, uas yog dav siv los ua raw khoom. Thaum siv los ua tus neeg saib xyuas kom meej, nws tsis tas yuav tsum tau ua ke nrog nitrate, thiab nws tuaj yeem tso pa oxygen los ntawm nws tus kheej ntawm qhov kub thiab txias kom ua kom pom tseeb. Txhawm rau txo cov nqi, nws feem ntau siv nrog sulfate hauv kev tsim cov iav pob kom ua tiav cov txiaj ntsig zoo.
2. Sulfate clarifier
Cov sulfates siv nyob rau hauv iav feem ntau yog sodium sulfate, barium sulfate, calcium sulfate, thiab sulfate nrog siab decomposition kub, uas yog ib tug high-kub clarifying tus neeg saib xyuas. Thaum sulfate siv los ua tus neeg saib xyuas kom meej, nws yog qhov zoo tshaj plaws los siv nws nrog oxidizing tus neeg sawv cev nitrate, thiab tsis tuaj yeem siv ua ke nrog tus neeg saib xyuas kom tsis txhob muaj sulfate decomposing ntawm qhov kub thiab txias. Sulfate feem ntau yog siv rau hauv lub raj mis iav thiab cov iav tiaj tus, thiab nws qhov ntau npaum li cas yog 1.0% -1.5% ntawm batch.
3. Halide clarifying tus neeg saib xyuas
Feem ntau suav nrog fluoride, sodium chloride, ammonium chloride thiab lwm yam. Fluoride feem ntau yog fluorite thiab sodium fluorosilicate. Tus nqi ntawm fluorite siv los ua tus neeg saib xyuas kom meej yog feem ntau xam raws li 0.5% fluorine nkag mus rau hauv pawg. Qhov dav dav npaum li cas ntawm sodium fluorosilicate yog 0.4% -0.6% ntawm sodium oxide nyob rau hauv iav. Thaum lub sij hawm melting ntawm fluoride, ib feem ntawm cov fluorine yuav tsim hydrogen fluoride, silicon fluoride, thiab sodium fluoride. Nws toxicity ntau dua li ntawm sulfur dioxide. Kev cuam tshuam ntawm huab cua yuav tsum tau xav txog thaum siv nws. Lub vaporization thiab volatilization ntawm sodium chloride ntawm qhov kub thiab txias tuaj yeem txhawb kev qhia meej ntawm cov kua iav. Qhov dav dav npaum li cas yog 1.3% -3.5% ntawm cov khoom siv batch. Ntau dhau yuav emulsify lub iav. Nws feem ntau yog siv los ua ib qho kev qhia meej rau boron-muaj iav.
Plaub, compound clarifier
Lub composite clarifier tsuas yog siv peb qhov kev pom zoo ntawm oxygen clarification, sulfur clarification thiab halogen clarification nyob rau hauv lub clarification tus neeg saib xyuas, thiab muab tag nrho cov kev ua si rau lub synergistic thiab superimposed los ntawm peb, uas muaj peev xwm ua tiav cov nyhuv ntawm tas mus li qhia meej thiab zoo heev txhim khu kev qha. muaj peev xwm. Nws yog ib qho kev qhia meej. Tus neeg sawv cev yog incomparable. Raws li txoj kev loj hlob theem, muaj: thawj tiam ntawm composite clarifiers, lub thib ob tiam ntawm composite clarifiers thiab lub thib peb tiam ntawm composite clarifiers. Lub cim thib peb ntawm kev sib xyaw clarifiers tseem hu ua lub cim tshiab ntawm cov phooj ywg zoo ib puag ncig cov lus piav qhia, uas yog ntsuab thiab ib puag ncig tus phooj ywg. Paub txog nws txoj kev nyab xeeb thiab kev ua haujlwm zoo, nws yog txoj kev txhim kho yav tom ntej ntawm iav fining tus neeg saib xyuas kev lag luam thiab qhov kev tsis pom zoo ntawm kev ua tiav cov qauv tsis muaj arsenic hauv kev lag luam iav. Qhov dav dav npaum li cas yog 0.4% -0.6% ntawm cov batch. Lub tshuab ua kom pom tseeb tau siv dav hauv lub raj mis iav, iav pob (nruab nrab alkali, tsis muaj alkali), iav tshuaj, hluav taws xob lub teeb ci iav, iav hluav taws xob, iav-ceramics thiab lwm yam iav. Cov khoom lag luam.
2. Sulfate clarifier
Cov sulfates siv nyob rau hauv iav feem ntau yog sodium sulfate, barium sulfate, calcium sulfate, thiab sulfate nrog siab decomposition kub, uas yog ib tug high-kub clarifying tus neeg saib xyuas. Thaum sulfate siv los ua tus neeg saib xyuas kom meej, nws yog qhov zoo tshaj plaws los siv nws nrog oxidizing tus neeg sawv cev nitrate, thiab tsis tuaj yeem siv ua ke nrog tus neeg saib xyuas kom tsis txhob muaj sulfate decomposing ntawm qhov kub thiab txias. Sulfate feem ntau yog siv rau hauv lub raj mis iav thiab cov iav tiaj tus, thiab nws qhov ntau npaum li cas yog 1.0% -1.5% ntawm batch.
