Barium chromate,nrog rau cov tshuaj formula BaCrO4 thiab CAS naj npawb 10294-40-3, yog ib tug daj crystalline compound uas tau pom muaj ntau yam kev siv. Kab lus no yuav piav qhia txog kev siv barium chromate thiab nws qhov tseem ceeb hauv kev lag luam sib txawv.
Barium chromate feem ntau yog siv los ua cov tshuaj tiv thaiv corrosion thiab ua cov xim hauv ntau yam kev siv. Nws cov khoom tiv thaiv corrosion ua rau nws muaj txiaj ntsig zoo hauv cov txheej txheem rau cov hlau, tshwj xeeb tshaj yog nyob rau hauv aerospace thiab automotive industries. Lub compound tsim ib txheej tiv thaiv ntawm cov hlau nto, tiv thaiv nws los ntawm xeb los yog corroding thaum raug mob hnyav ib puag ncig. Qhov no ua rau nws yog ib qho tseem ceeb muaj nyob rau hauv kev tsim cov khoom zoo, cov txheej txheem ntev ntev rau cov hlau nto.
Ntxiv nrog rau nws lub luag haujlwm ua cov tshuaj tiv thaiv corrosion, barium chromate kuj tseem siv los ua cov xim hauv kev tsim cov xim, inks, thiab plastics. Nws cov xim daj vibrant thiab kub kub ruaj khov ua rau nws muaj kev xaiv nrov rau kev faib xim rau ntau yam khoom. Cov xim tau los ntawm barium chromate paub txog nws qhov zoo tshaj plaws lightfastness thiab tsis kam mus rau cov tshuaj, ua rau nws haum rau siv nyob rau hauv sab nraum zoov daim ntaub ntawv thiab nyob rau hauv cov khoom uas yuav tsum tau mus ntev lub sij hawm.
Tsis tas li ntawd,barium chromatetau ua haujlwm nyob rau hauv kev tsim cov foob pob hluav taws thiab cov ntaub ntawv pyrotechnic. Nws lub peev xwm los tsim cov xim daj-ntsuab ntsuab thaum ignited ua rau nws muaj txiaj ntsig zoo hauv kev tsim cov khoom siv hluav taws xob pom kev zoo nkauj. Cov khoom siv hluav taws xob tiv thaiv hluav taws xob kuj tseem ua rau nws cov txiaj ntsig zoo hauv kev siv pyrotechnic, kom ntseeg tau tias cov xim tsim nyob rau hauv vivid thiab zoo ib yam thaum lub sij hawm combustion.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum barium chromate muaj ntau yam kev siv hauv kev lag luam, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo saib xyuas vim nws cov tshuaj lom neeg. Kev cuam tshuam rau barium chromate tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv, thiab kev ntsuas kev nyab xeeb tsim nyog yuav tsum tau ua thaum tuav thiab siv cov khoom uas muaj cov khoom sib xyaw no. Kev ua pa kom raug, cov cuab yeej tiv thaiv tus kheej, thiab ua raws li cov lus qhia kev nyab xeeb yog qhov tseem ceeb kom txo qis kev pheej hmoo ntawm kev noj qab haus huv cuam tshuam nrog barium chromate.
Nyob rau hauv xyoo tas los no, muaj kev loj hlob tseem ceeb ntawm txoj kev loj hlob ntawm ib puag ncig tus phooj ywg lwm txoj kev rau barium chromate vim nws toxicity. Cov neeg tsim khoom thiab cov kws tshawb fawb tau nquag tshawb nrhiav cov tshuaj hloov pauv uas muaj cov tshuaj tiv thaiv corrosion zoo sib xws thiab cov xim xim thaum ua rau muaj kev pheej hmoo tsawg rau tib neeg kev noj qab haus huv thiab ib puag ncig. Qhov kev siv zog txuas ntxiv no qhia txog kev cog lus ntawm kev lag luam los ua qhov tseem ceeb ntawm kev nyab xeeb thiab kev ruaj ntseg hauv lawv cov txheej txheem tsim khoom.
Hauv kev xaus,barium chromate, nrog rau nws tus lej CAS 10294-40-3,plays lub luag haujlwm tseem ceeb hauv ntau daim ntawv thov kev lag luam. Nws siv los ua cov tshuaj tiv thaiv corrosion, pigment, thiab cov khoom siv hauv cov ntaub ntawv pyrotechnic qhia txog nws txoj kev siv ntau yam thiab qhov tseem ceeb hauv ntau qhov chaw. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tau ua qhov kev sib xyaw no nrog kev ceev faj vim nws cov tshuaj lom neeg. Raws li kev lag luam txuas ntxiv mus ntxiv, kev tshawb nrhiav lwm txoj hauv kev nyab xeeb rau barium chromate underscores qhov kev cog lus los txhawb cov khoom lag luam kev nyab xeeb thiab kev ruaj ntseg ib puag ncig.
