1. Lub zog zais
Thaum ib yam khoom raug coated nrog qee yam xim, cov xim hauv cov xim tuaj yeem npog cov xim tom qab ntawm qhov chaw ntawm cov khoom pleev xim, kom cov xim tom qab tsis tuaj yeem tshwm sim los ntawm cov xim.
Hniav fais fab=pigment mass (g) / deg cheeb tsam ntawm cov khoom yuav tsum tau coated (CM2)
2. Thaum tshav kub kub tsis kam
Nws txhais tau hais tias ntawm ib qho kev ua haujlwm kub, cov xim tsis dhau qhov kev hloov pauv hauv qhov ntxoov ntxoo thiab lub zog tinting. Nws hais txog qhov tsis kam ntawm cov xim rau qhov kev hloov ntawm tinting lub zog los ntawm kev ua haujlwm kub.
Nco ntsoov:
① Thaum xav txog qhov kub thiab txias tsis kam ntawm cov xim, nws tseem yuav tsum tau xav txog nws lub sijhawm cua sov.
② Dab tsi yuav tsum tau xav txog yog qhov thermal stability ntawm cov xim xim nws tus kheej.
3. Lub teeb ceev ceev
Nws hais txog kev hloov xim ntawm cov xim nyob rau hauv irradiation ntawm lub teeb. Qhov ntsuas lub teeb nrawm yog qhov zoo tshaj plaws nrog qib yim thiab qhov phem tshaj plaws nrog qib thawj.
4. Huab cua tsis kam
Nws hais txog kev hloov pauv ntawm cov xim hauv ntau hom kev nyab xeeb, suav nrog lub teeb pom kev thiab ultraviolet lub teeb, noo noo thiab kub, thiab xim ntawm cov khoom. Tom qab cov organic pigment yog irradiated los ntawm lub teeb, nws yuav ua rau cov kev hloov nyob rau hauv lub molecular configuration ntawm cov xim, uas yuav cuam tshuam qhov txo nyob rau hauv saturation, thiab txawm ploj mus rau hauv grey los yog dawb. Cov huab cua tsis kam ntawm cov xim yog ntsuas raws li 5 qib, thiab 5 qib yog qhov zoo tshaj plaws.
5. Kev tsiv teb tsaws chaw
Nws txhais tau hais tias cov pigment migrate los ntawm sab hauv cov yas mus rau saum npoo ntawm cov khoom los yog mus rau cov khoom yas uas nyob ib sab thiab hnyav thaum nws migrate. Hauv kev ntsuam xyuas, qib 5 txhais tau tias tsis muaj kev tsiv teb tsaws chaw, thiab qib 1 txhais tau tias kev tsiv teb tsaws hnyav heev.
Kev ua haujlwm tshwj xeeb yog raws li hauv qab no:
① Blooming: Thaum lub sij hawm cia ntawm chav tsev kub, cov xim pigment migrate los ntawm cov yas / pigment system mus rau saum npoo.
② Cov kuab tshuaj exudation: Pigment Cheebtsam nkag mus rau cov kuab tshuaj nyob ib sab, dyes thiab qee cov organic pigments qhia qhov tshwm sim no.
③ Yas / yas tiv tauj tsiv teb tsaws.
6. Roj nqus
Hais txog tus nqi ntawm cov roj refined linseed absorbed los ntawm ib tug pigment qauv nyob rau hauv tej yam kev mob, uas yuav qhia tau los ntawm ntim / loj los yog loj / loj. Tus nqi ntawm cov roj absorption muaj qee yam cuam tshuam rau lub leveling thiab gloss ntawm txheej.
7. Solvent resistance
Nws txhais tau hais tias tom qab cov xim nyob rau hauv kev sib cuag nrog cov kuab tshuaj, ib co pigments yuav yaj nyob rau hauv cov kuab tshuaj, uas yuav ua rau cov kuab tshuaj stains. Cov kuab tshuaj tsis kam ntawm cov xim yog hais txog kev ua haujlwm ntawm cov xim los tiv thaiv cov kuab tshuaj dissolution thiab ua rau cov kuab tshuaj staining.
8. Cov ntsiab lus muag muag
Qhov kub ntawm lub thermoplastic resin hloov los ntawm lub xeev ruaj khov mus rau lub xeev khov yog hu ua softening point. Yog hais tias lub softening point yog tsawg heev, cov khoom yog yooj yim rau agglomerate; Yog hais tias lub softening point yog siab dhau lawm, qhov kev txhaj tshuaj kub yuav tsum tau nce, txwv tsis pub cov pigment yog nyuaj rau yaj thiab disperse.
9. Decomposition point
Qhov kub ntawm cov resin puas thiab decomposed ntawm qhov kub siab yog hu ua decomposition point. Lub decomposition point tuaj yeem cuam tshuam qhov thermal stability ntawm cov resin.
10. Particle loj
Qhov loj me me yog qhov ntsuas tseem ceeb uas qhia txog qhov loj me ntawm cov xim fluorescent, thiab chav tsev yog um. Lub finer particle loj, qhov yooj yim cov khoom yog disperse thiab yaj mus rau hauv cov khoom downstream.
