Ntsiab nta

Nyob ntawm seb cov tshuaj muaj pes tsawg leeg, cov xim xim rau qhob muaj xws cov yam ntxwv raws li corrosion thiab thermal stability, thiab xim. Cov xim muaj pes tsawg leeg muaj cov nram qab zog:

• Lightfastness - zas kom tus thawj, los yog nyob ze rau nws cov xim thaum raug rau ultraviolet tawg. Qhov tseem resistant mus rau zoo xws los ntawm tej yam ntuj tso pigments.
• Nkaum hwj chim - lub peev xwm pigmenting muaj pes tsawg leeg thaum ua ntawv thov mus rau qhov chaw ntawm cov xim thaiv.
• Dispersiveness - nyob ntawm seb yuav ua li cas npaum li cas twb finely as xim rau coloring qhob. Lub finer thiab finer sib tsoo hais, ntau dua qhov lub coloring muaj peev xwm thiab kev pab them nqi pes tsawg leeg.
• Tshuaj kuj mus alkalis - xim xim stability rau alkali kawm grout.
• Roj haum, uas yog to taub raws li ib lub sij hawm los tuav cov xim hais rau ntawm qhov chaw ntawm qhov yuav tsum tau npaum li cas ntawm phau ntawv muaj pes tsawg leeg (roj). Nws nyob rau ntawm lub keeb kwm thiab dispersion ntawm pigments. Tus me dua cov nqi, qhov ntau check thiab yig xav txheej.
