ACETATE POLY ANTI-STATIC, ANTI-ULTRAVIOLET PUIPUIA PA'U IE MO Ofu AC9218

1. Alkali tetee
E le'i fa'aleagaina ai le acetate agent vaivai, ma e la'ititi lava le pa'u o le mamafa.Pe a fetaui ma alkali malosi, aemaise lava diacetate fiber, e faigofie ona deacetylate, e mafua ai le paʻu o le mamafa, malosi ma le faʻaitiitia o le modulus.O le mea lea, o le pH o le vaifofo mo le togafitia o le cellulose acetate e le tatau ona sili atu i le 7.0.I lalo o tulaga masani o le fufuluina, e malosi le chlorine bleaching tete'e ma e mafai fo'i ona fa'amama-mamago i le tetrachloroethylene.

2. Tete'e i solvents organic
Cellulose acetate e matua solu i le acetone, DMF ma glacial acetic acid, ae le mafai ona solu i ethanol ma tetrachloroethylene.E tusa ai ma nei uiga, e mafai ona faʻaaogaina le acetone e pei o le soli vili o le acetate fiber, ma e mafai ona faʻaaogaina le tetrachlorethylene e faʻagogo mama acetate fiber ie.
3. Tete'e o le acid

Acetic acid fiber e lelei le mautu, ma o le sulfuric acid masani, hydrochloric acid ma le nitric acid o le a le afaina ai le malosi, luster ma le faʻalauteleina o le alava i totonu o se vaega faʻatonuga.Ae e mafai ona faʻamavaeina i totonu o le sulfuric acid concentrated, concentrated hydrochloric acid ma concentrated nitric acid.

4. Lanu lanu

E ui lava o le cellulose acetate e mafua mai i le cellulose, i le taimi o le esterification process, o se vaega tele o vaega polar hydroxyl i luga o le kulukose mama o le cellulose ua suia e vaega acetyl.O le mea lea, o vali e masani ona faʻaaogaina i le valiina o le fiber cellulose e toetoe lava a leai se sootaga mo le cellulose acetate ma e faigata ona vali.O vali e sili ona talafeagai mo alava acetate o vali faʻasalalau e maualalo le mamafa mole mole ma tutusa fua faʻalanu.

O le acetate fiber poʻo le ie ua valiina i vali faʻasalalau o loʻo i ai le lanu susulu, lelei le faʻaogaina o le tulaga, maualuga le vaivai o le vali, maualuga le lanu vave ma le chromatography atoatoa.
