PIGMENT YELLOW 139 – Folasaga ma le Fa'aaogaina
Pigment Yellow 139 ose lanu samasama paolo mumu e maualuga le malosi o le lanu pe a faʻaaogaina i palasitika. E fautuaina e fai ma sui o le diarylide ma le chromate pigments. Ole fa'alavelave fa'afuase'i ole PY139 fa'atasi ai ma mea fa'aopoopo alkaline e mafai ona ta'ita'iina ai le fa'alilolilo ma fa'aitiitia mea totino.
O le isi avanoa o Pigment Yellow 139 o le, e maualalo le warping i le HDPE. E fetaui mo PVC, LDPE, PUR, paʻu, fila PP, ma faʻatapulaʻa faʻaoga ile HDPE/PP.
I mea fa'apipi'i, Pigment Yellow 139 ose lanu samasama mumu ma e sili ona vave i le malamalama ma le tau, ae maise i totonu o paolo loloto. Opacity lelei tele mo se pa'u oona. E sili ona talafeagai mo le gaosiga o lanu samasama mataʻutia mo vali e leai se taʻitaʻi poʻo vali maualalo. E tatau ona manatua o le tetee atu i alkalis malosi tele i nisi faiga faʻapipiʻi e le faamalieina. Faatasi ai ma pigments inorganic i nai lo chromium samasama. Talafeagai mo Pa'u Ta'avale, Pa'u Alamanuia, Pa'u teuteu. E mafai ona e vaʻai i le faʻavave i solvents e lelei uma i lalo faʻamatalaga fesoʻotaʻi, faʻapea foʻi ma ona uiga sili ona vave.
O le isi autu e ta'uta'ua, o le to'atele o tagata latou te fa'aaogaina Pigment Yellow 139 e sui ai Pigment Yellow 83 i le taimi nei. I aso ua tuanaʻi, Pigment Yellow 83 ua faʻaaogaina lautele. Ona o le si'itia o le tau o mea mata'utia ma le le lava o sapalai, Pigment Yellow 139, lea e tutusa lona paolo (lanu samasama), e suitulaga i le tau aoga. Fa'amolemole maitau mai le vevela, Pigment Yellow 139 e mafai ona o'o i le 240C a'o Pigment Yellow 83 e na'o le 200C. Aua le fa'aogaina le Pigment Yellow 83 i polymers ile vevela e sili atu ile 200C. O le pala o Diarylide Pigments i polymers i le vevela i luga atu o le 200C e mafai ona maua ai le tele o amine manogi leaga.
So'oga i Pigment Yellow 139 Fa'amatalaga:Fa'aaogāga palasitika; Vali ma le fa'apipi'iina.
