Mee ka ike tinting dịkwuo mma, mụbaa ngosipụta nke agba. Mee ka saturation na nghọta nke pigmenti organic dịkwuo mma, ma nwekwuo ike izo ezo nke pigmenti inorganic.

Mmetụta na arụ ọrụ ihe nkiri agba

Dispersant agaghị ahapụ ihe nkiri agba mgbe ihe nkiri ahụ gasịrị, ma dị ka akụkụ na-adịgide adịgide nke ihe nkiri agba dị na ihe nkiri agba, ọ dịghị obere mmetụta na arụmọrụ nke ihe nkiri ahụ.

Mmetụta na mgbochi mmiri:

Site na ụkpụrụ omume nke dispersant, ihe kacha mkpa nke dispersant bụ surfactant, na amphiphilic Njirimara. Ya mere, onye na-ekesa ga-enweghi ike inwe ụfọdụ hydrophilic, na ihe nkiri agba nwere mmetụta dị ukwuu na nkwụsị mmiri.

Sv-246h mmiri dabeere superdispersant bụ a hydrophobic gbanwetụrụ ngwaahịa, ihe nkiri akọrọ, agaghị emetụta ihe nkiri n'onwe ya mmiri na-eguzogide.

Mmetụta na gloss:

The gloss nke agba film elu na-tumadi ewepụtara site echiche nke ìhè na agba film elu, na elu ala na-adabere na urughuru size nke ọ bụla akụrụngwa, nakwa dị ka ndakọrịta na nkesa ala.

Mgbasa mgbasa ozi, nkwụsi ike bụ ihe ịrụ ụka adịghị ya na ọ na-enye aka dị ukwuu na gloss nke ihe nkiri agba. Ma mkpa ka tụlee dispersant onwe ya na resin onwe ya ndakọrịta.
