WamvulaBarium sulphate(BaSO4), EINECS No. 231-784-4, ndi gulu lofunidwa kwambiri lomwe limadziwika ndi chiyero chake chapadera, ndi osachepera 98% BaSO4. Mankhwalawa amagwiritsidwa ntchito m'mafakitale osiyanasiyana kuphatikiza utoto, zokutira komanso ngakhale kupanga mabatire. Makhalidwe ake apadera amachititsa kuti ikhale yofunika kwambiri pazochitika zambiri, kuonetsetsa zotsatira zabwino kwambiri.

Chimodzi mwazinthu zodziwika bwino za precipitated barium sulphate ndi kuthekera kwake kupangidwa pamlingo waukulu. Opanga ali ndi njira zokometsera kuti awonetsetse kuti akutumiza mwachangu popanda kusokoneza mtundu. Kuchita bwino kumeneku ndikofunikira kwambiri pamakampani omwe amadalira njira zogulitsira zomwe zimangochitika munthawi yake kuti zikwaniritse zosowa zopanga. Kaya ndi pulojekiti yokutira yayikulu kapena kugwiritsa ntchito batri yapadera, kupezeka kwa barium sulfate wapamwamba kwambiri ndikosintha masewera.

Barium sulphate ndi pigment yofunika komanso yodzaza mumakampani opanga utoto ndi zokutira. Ndi mamolekyu a BaSO4, imapangitsa kuti utoto ukhale wosawoneka bwino komanso wosasunthika, ndikupangitsa kuti utoto ukhale wokongola komanso wokhalitsa. Kuonjezera apo, kukhazikika kwake kwa mankhwala kumatsimikizira kuti sichidzatsutsana ndi zosakaniza zina, zomwe zimapangitsa kukhala chisankho chodalirika kwa opanga.

Kuphatikiza apo, kugwiritsa ntchito barium sulfate pakupanga batri kumawonetsa kusinthasintha kwake. Monga mankhwala a sulfate, amathandizira kukonza magwiridwe antchito ndi magwiridwe antchito a mabatire, ndikupangitsa kuti ikhale gawo lofunikira la mayankho amakono amphamvu.

Pomaliza, mpweya wa barium sulphate ndi woposa pawiri, ndiye mwala wapangodya wa mafakitale osiyanasiyana. Ndi chiyero chake chapamwamba, kuthekera kwakukulu kopanga ndi kugwiritsa ntchito mosiyanasiyana, BaSO4 ikupitilizabe kugwira ntchito yofunikira pakupita patsogolo kwaukadaulo komanso kuwongolera zogulitsa. Pamene makampani akukula, kufunikira kwa barium sulphate yapamwamba mosakayikira kudzakula, kugwirizanitsa malo ake pamsika.
