Barium chromate,ndi mankhwala chilinganizo BaCrO4 ndi CAS nambala 10294-40-3, ndi chikasu crystalline pawiri kuti wapeza ntchito zosiyanasiyana mafakitale. Nkhaniyi ifotokoza za kugwiritsidwa ntchito kwa barium chromate komanso kufunikira kwake m'mafakitale osiyanasiyana.
Barium chromate imagwiritsidwa ntchito ngati choletsa corrosion inhibitor komanso ngati pigment pamagwiritsidwe osiyanasiyana. Zomwe zimalepheretsa dzimbiri kumapangitsa kuti ikhale yofunika kwambiri pakupaka zitsulo, makamaka m'mafakitale apamlengalenga ndi magalimoto. Pawiriyi imapanga chinsalu choteteza pamwamba pazitsulo, kuti chisachite dzimbiri kapena chiwonongeko chikakumana ndi zovuta zachilengedwe. Izi zimapangitsa kuti zikhale zofunikira kwambiri popanga zovala zapamwamba, zokhala ndi nthawi yayitali pazitsulo zazitsulo.
Kuphatikiza pa ntchito yake ngati corrosion inhibitor, barium chromate imagwiritsidwanso ntchito ngati utoto popanga utoto, inki, ndi mapulasitiki. Mtundu wake wachikasu wonyezimira komanso kukhazikika kwa kutentha kumapangitsa kukhala chisankho chodziwika bwino popereka utoto kuzinthu zambiri. Pigment yochokera ku barium chromate imadziwika chifukwa cha kupepuka kwake komanso kukana mankhwala, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito panja komanso pazinthu zomwe zimafunikira kukhazikika kwanthawi yayitali.
Komanso,barium chromateadagwiritsidwa ntchito popanga zozimitsa moto ndi zida za pyrotechnic. Kuthekera kwake kutulutsa mitundu yowala, yachikasu-yobiriwira ikayatsidwa kumapangitsa kuti ikhale gawo lofunika kwambiri popanga zowonetsa zowoneka bwino. Zomwe zimalimbana ndi kutentha kwapawirizi zimathandizanso kuti zitheke bwino pakugwiritsa ntchito pyrotechnic, kuwonetsetsa kuti mitundu yomwe imapangidwa imakhalabe yowoneka bwino komanso yosasinthasintha pakuyaka.
Ndikofunika kuzindikira kuti ngakhale barium chromate ili ndi ntchito zingapo zamafakitale, ndikofunikira kuigwira mosamala chifukwa cha poizoni. Kuwonetsedwa kwa barium chromate kumatha kubweretsa ngozi ku thanzi, ndipo njira zoyenera zotetezera ziyenera kutsatiridwa pogwira ndikugwiritsa ntchito zinthu zomwe zili ndi mankhwalawa. Mpweya wabwino, zida zodzitetezera, komanso kutsatira malangizo achitetezo ndikofunikira kuti muchepetse zoopsa zomwe zingachitike paumoyo wokhudzana ndi barium chromate.
M'zaka zaposachedwa, pakhala kugogomezera kwambiri pakukula kwa njira zoteteza zachilengedwe m'malo mwa barium chromate chifukwa cha kawopsedwe. Opanga ndi ofufuza akuyang'ana mwachangu mankhwala olowa m'malo omwe amapereka zolepheretsa dzimbiri zofananira komanso mawonekedwe a pigment pomwe akuyika chiwopsezo chochepa ku thanzi la anthu komanso chilengedwe. Khama lomwe likupitilira izi likuwonetsa kudzipereka kwa mafakitale kuti aziyika patsogolo chitetezo ndi kukhazikika munjira zawo zopangira zinthu.
Pomaliza,barium chromate, yokhala ndi nambala yake ya CAS 10294-40-3,imagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana. Kugwiritsiridwa ntchito kwake monga corrosion inhibitor, pigment, ndi chigawo chimodzi mu zipangizo za pyrotechnic kumawonetsa kusinthasintha kwake komanso kufunikira kwake m'magulu osiyanasiyana. Komabe, ndikofunikira kuti mugwiritse ntchito mankhwalawa mosamala chifukwa cha poizoni wake. Pamene mafakitale akupitabe patsogolo, kufufuza kwa njira zina zotetezeka ku barium chromate kumatsimikizira kudzipereka pakupititsa patsogolo chitetezo cha mankhwala ndi kusungidwa kwa chilengedwe.
