Ntuj Barium Sulphate vs Precipitated Barium Sulphate: Kev Ua Haujlwm & Tus Nqi Sib Piv

Barium sulphate muaj nyob rau hauv ob hom: ntuj barium sulphate (muab los ntawm cov ntxhia barite) thiab precipitated barium sulphate (chemically synthesized). Thaum ob daim ntawv qhia tib yam tshuaj formula (BaSO₄), lawv cov txheej txheem tsim khoom, cov yam ntxwv ua tau zoo, thiab cov nqi sib txawv. Rau cov neeg yuav khoom thoob ntiaj teb thiab cov neeg siv khoom lag luam, kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau kev xaiv txoj cai ntawm barium sulphate rau cov kev siv tshwj xeeb, kev ua haujlwm zoo, thiab tswj cov nqi yuav khoom.

 

Ntuj barium sulphate yog muab rho tawm los ntawm barite ore los ntawm lub cev sib tsoo thiab purification txheej txheem. Nws yog feem ntau tsis tshua kim tshaj precipitated barium sulphate, raws li nws cov khoom muaj tsawg dua cov kauj ruam tshuaj. Ntuj barium sulphate muaj purity ntau ntawm 85-95%, nrog cov kab tsis huv xws li silica, calcium carbonate, thiab hlau oxides. Nws qhov loj me me yog qhov tsis sib xws thiab sib txawv, nyob ntawm cov txheej txheem sib tsoo, ua rau nws tsim nyog rau cov ntawv thov uas siab purity thiab uniform particle loj tsis tseem ceeb.

 

Precipitated barium sulphate yog tsim los ntawm cov tshuaj tiv thaiv, feem ntau los ntawm reacting barium chloride nrog sodium sulphate, ua rau cov khoom ntshiab heev (98-99.5% purity) nrog cov khoom me me thiab cov duab. Nws muaj superior whiteness (95–98) thiab dispersibility piv rau tej yam ntuj tso barium sulphate, ua rau nws zoo tagnrho rau siab-kawg daim ntaub ntawv xws li automotive coatings, siab - zoo plastics, thiab tshuaj cov khoom. Cov txheej txheem tsim khoom tswj tau tso cai rau kev hloov pauv ntawm cov khoom me me, kom ntseeg tau tias kev ua haujlwm zoo ib yam ntawm cov khoom siv.

 

Kev ua tau zoo sib txawv ntawm ob daim ntawv yog pom tseeb tshaj plaws hauv lawv daim ntawv thov. Tej yam ntuj tso barium sulphate feem ntau yog siv nyob rau hauv qis - cov nqi siv xws li, cov ntaub ntawv siv, thiab roj drilling kua, qhov twg nws cov nqi qis thiab kev ua tau zoo raws li kev lag luam. Precipitated barium sulphate, ntawm qhov tod tes, yog qhov zoo dua rau cov qib siab -txheej txheej, zaub mov- qib plastics, thiab kev siv tshuaj kho mob, qhov uas siab purity, zoo li qhov loj me, thiab zoo heev dispersibility yog qhov tseem ceeb.

 

Tus nqi yog qhov tseem ceeb rau cov neeg yuav khoom. Natural barium sulphate feem ntau yog 20-30% pheej yig dua li precipitated barium sulphate, ua rau nws tus nqi -kev xaiv zoo rau loj- nplai, qis- daim ntawv thov nqi. Precipitated barium sulphate, thaum kim dua, muaj kev ua tau zoo dua, txo qhov xav tau ntxiv cov khoom ntxiv thiab txhim kho qhov zoo ntawm cov khoom kawg. Rau cov neeg xa tawm, muab ob daim ntawv tso cai rau lawv ua raws li ntau yam ntawm cov neeg yuav khoom xav tau, los ntawm tus nqi -rhiab rau siab - daim ntawv thov kev ua tau zoo.

 

Thaum xaiv cov ntaub ntawv ntuj thiab nag, cov neeg yuav khoom yuav tsum xav txog lawv cov kev thov tshwj xeeb, kev xav tau purity, thiab kev txwv nyiaj txiag. Los ntawm kev nkag siab txog qhov ua tau zoo thiab tus nqi sib txawv ntawm ob, lawv tuaj yeem xaiv qhov zoo tshaj plawsbarium sulfaterau lawv cov txheej txheem tsim khoom, ua kom zoo thiab tus nqi -effectiveness.
