Dab tsi yog lub luag haujlwm ntawm barium sulfate hloov pauv hauv cov txheej txheem ntawm kev sib txuas ntawm nano barium sulfate?

Nyob rau hauv tus txheej txheem ntawm kev npaj nano barium sulfate, cov txheej txheem tseem ceeb tau muab faib ua tshuaj synthesis thiab nag lossis daus. Cov hom kev hloov kho, cov pawg uas tsis yog-bridging hydroxyl pawg (-OH) ntawm nano barium sulfate hais yog hloov mus rau ether bonds (-O-) thaum lub sij hawm npaj ntawm barium sulfate nws tus kheej, uas yuav tsum tau ib tug haum dispersant los daws. Lub luag haujlwm tseem ceeb ntawm calcium sulfate modifier yog lub tsho tiv no thiab hloov cov barium sulfate thaum lub sij hawm crystallization txheej txheem, thiab txhim kho dispersibility ntawm barium sulfate. Nyob rau tib lub sijhawm, tus nqi ntawm kev hloov kho, qhov kub thiab txias, qhov sib tov, qhov loj me, thiab lwm yam kuj yog qhov tseem ceeb cuam tshuam rau qhov zoo ntawm cov khoom siv hluavtaws nano barium sulfate. Tau kawg, txhua yam khoom tseem yuav tsum tau kuaj xyuas seb puas muaj, thiab kev xyaum yog tus qauv rau kev sim seb cov khoom puas ua tau.
