Uila felanulanua'i malu puipuialanu lanu:
Matou te gaosia ituaiga e lua: phosphors organic & phosphors inorganic
O se phosphors faʻaola: Mumu, samasama-meamata, samasama, lanumeamata ma le lanumoana.
B phosphors inorganic: Mumu, samasama-meamata, lanumeamata, lanumoana, paepae, Viole.
Uv fluorescent saogalemu pigments auala lomitusi
Lomitusi offset, lomitusi screen, lomitusi intaglio ma lomitusi flexographic.
U'u fa'amalama fa'amalama fa'aulaula Uiga
O se phosphors organic
1. Fluorescence lanu susulu, e leai se mana natia, fua faatatau o le malamalama o le 90%.
2.Solubility lelei, e mafai ona fa'amavaeina ituaiga uma o solu suauu.Ona o le solvency eseese, faamolemole filifili e tusa ai ma manaoga eseese o le faaaogaina.
3. E iai i le fa'asologa o vali, e tatau ona gauai atu i fa'afitauli suiga lanu.
4. ona o le leaga o le tetee o le tau, pe a e manaʻomia le faʻaopoopoina o isi faʻamautu.
5. Tete'e o le vevela: maualuga le vevela o le 200 ℃, fetaui i totonu ole 200 ℃ fa'agaioiga vevela maualuga.
B phosphors e le fa'aletino
1. Fluorescence lanu susulu, mana lelei natia (opacity e mafai ona faaopoopo saoloto sui).
2. Fine spherical particles, faigofie ona taape, 98% o le lautele e uiga i 1-10μm.
3. Lelei faʻafefe vevela: maualuga le vevela o le 600, talafeagai mo le faʻaogaina o le vevela maualuga o faiga eseese.
4. Lelei faʻafefete faʻafefe, acid, alkali, mautu maualuga.
5. E leai se suiga lanu, o le a le faʻaleagaina.
6. Le non-o'ona, e le lofia pe a vevela formalin, meataalo ma pusa meaai e mafai ona faaaoga mo valivali.
7. E le faʻafefete le tino lanu, pe a i totonu o le masini tui mo le faʻafefe, e mafai ona e faʻasaoina faiga faʻamamā.
Uv fluorescent saogalemu pigments Fa'aoga
UV fluorescent puipuiga pigments E mafai ona faʻaopoopo saʻo i le vaitusi, vali, faia le puipuiga malu aafiaga, fua faatatau fautuaina o le 1% i le 10%, e mafai ona faaopoopo tuusao i mea palasitika mo tui extrusion, fua faatatau fautuaina o le 0.1% i le 3%.
1. e mafai ona faʻaaogaina i le tele o palasitika e pei ole PE, PS, PP, ABS, acrylic, urea, melamine, polyester O le resini lanu felanulanuaʻi.
2. Vaitusi: mo se tetee lelei solvent ma e leai se suiga lanu o le lolomiina o le oloa maeʻa e le faʻaleagaina.
3. Vali: tete'e i gaoioiga mata tolu taimi sili atu le malosi nai lo isi ituaiga, fluorescence susulu umi e mafai ona faʻaaogaina i luga o faʻasalalauga ma Puipuiga Lomiga lapataiga atoa.
