iindaba

ImvulaBarium sulfate(BaSO4), i-EINECS No. 231-784-4, i-compound efunwa kakhulu eyaziwayo ngokucoceka kwayo okukhethekileyo, kunye nobuncinci be-98% BaSO4. Le khemikhali isetyenziswa kuluhlu olubanzi lwemizi-mveliso kubandakanya iipeyinti, iingubo kunye nokwenza iibhetri. Iimpawu zayo ezizodwa zenza ukuba ibe yinto ebalulekileyo kwizicelo ezininzi, ukuqinisekisa iziphumo eziphezulu.

Enye yeempawu ezibalaseleyo ze-barium sulfate ye-precipitated yikhono layo lokuveliswa kwinqanaba elikhulu. Abavelisi baneenkqubo eziphuculweyo zokuqinisekisa ukuhanjiswa ngokukhawuleza ngaphandle kokuthomalalisa umgangatho. Oku kusebenza kakuhle kubalulekile kwishishini elixhomekeke kwikhonkco lobonelelo ngexesha elifanelekileyo ukuhlangabezana neemfuno zemveliso. Nokuba yiprojekthi enkulu yokugquma okanye isicelo esikhethekileyo sebhetri, unikezelo lwe-barium sulfate ekumgangatho ophezulu ngumtshintshi womdlalo.

I-Barium sulfate yi-pigment ebalulekileyo kunye nokuzalisa kwishishini lepeyinti kunye neengubo. Ngefomula ye-molecular ye-BaSO4, iphakamisa ukungabonakali kunye nokuqina kwepeyinti, ukubonelela ngobuhle kunye nexesha elide eligudileyo. Ukongezelela, ukuzinza kwayo kweekhemikhali kuqinisekisa ukuba ayiyi kusabela kakubi kunye nezinye izithako, okwenza kube yinto ethembekileyo yokukhetha abaqulunqi.

Ngapha koko, ukusetyenziswa kwe-barium sulfate kwimveliso yebhetri kuqaqambisa ukuguquguquka kwayo. Njengomchiza we-sulfate, inceda ukuphucula ukusebenza kunye nokusebenza kweebhetri, okwenza kube yinxalenye ebalulekileyo yezisombululo zamandla zanamhlanje.

Ukuqukumbela, i-precipitated barium sulfate ingaphezulu nje komxube, ilitye lembombo lamashishini ahlukeneyo. Ngokucoceka kwayo okuphezulu, amandla amakhulu okuvelisa kunye nezicelo ezahlukeneyo, i-BaSO4 iyaqhubeka nokudlala indima ebalulekileyo ekuphuculweni kwezobuchwepheshe kunye nokuphucula umgangatho wemveliso. Njengoko imboni ikhula, imfuno ye-barium sulfate esemgangathweni ngokuqinisekileyo iya kukhula, idibanise isikhundla sayo kwimarike.
