Kev Tshawb Fawb Txog Cov nyhuv ntawm cov dej noo ntawm Organic Pigments

Organic pigment particles muaj lub zog siab cov ntsiab lus ntawm lawv qhov chaw, thiab lawv qhov chaw ib txwm adsorbs qee yam khoom, nrog dej yog ib qho ntawm lawv. Cov dej xa mus rau ntawm no yog hais txog cov dej ntub dej, uas yog cov dej adsorbed rau ntawm cov xim, tsis suav nrog cov dej khi rau hauv cov tshuaj lom neeg ntawm cov xim. Nws yog tsis yooj yim sua rau lub pigment nto yuav tsis muaj dej kiag li. Txawm hais tias cov xim qhuav yog ci, nws tseem yuav nqus dej ib zaug rau saum huab cua kom txog thaum nws nyob rau theem sib npaug nrog qhov kub thiab av noo.
Qhov tsim nyog noo noo cov ntsiab lus nyob rau hauv cov organic pigments yog tsim nyog, vim hais tias muaj cov dej noo tuaj yeem cuam tshuam rau kev sib tsoo thiab dispersion ntawm pigments hauv coatings, uas yog tshwj xeeb tshaj yog nyob rau hauv Suav pigments. Yog tias cov dej noo ntawm cov xim qis dhau lawm, nws nyuaj rau zom, thiab yog tias cov ntsiab lus noo noo siab dhau lawm, nws yuav ua rau muaj kev tiv thaiv coarsening.
Feem ntau, noo noo yog flocculant rau xim pleev xim, thiab cov dej noo tsim nyog yuav tsis ua rau ntau dhau flocculation. Lub xub ntiag ntawm noo noo tuaj yeem cuam tshuam rau ntau yam khoom ntawm cov xim, xws li xim ci thiab kev nqus roj. Yog li ntawd, raws li kev siv cov organic pigments sib txawv, qhov tsim nyog noo noo cov ntsiab lus ntawm cov pigments sib txawv tau teev tseg. Feem ntau, cov dej noo ntawm cov pigments tsis tshaj 1%, thaum rau Hualan, nws yog 4%. Cov pa roj carbon dub tuaj yeem qhia cov dej noo txog li 10%.
