Formulare ya molecular: Na₃Po₄Na₃Po₄· H₂O, na₃Po₄· 12h₂O

Uburemere bwa molekile: Anhydrous: 163.94; Monohyrate: 181.96; Dodecahydrate: 380.18

Cas: Anhydrous: 7601-54-9; Dodecahydrate: 10101-89-0

Inyuguti: Ni ibara ritagira ibara cyangwa ryera, ifu cyangwa ifu cyangwa kristu ya granule. Nibihe bidasanzwe, byoroshye gushonga mumazi ariko bidahwitse muri socit organic. Dodecahyddrate ibura amazi yose kandi ahinduke anhydrous iyo ubushyuhe buzagera kuri 212 ℃. Igisubizo ni alkaline, ruswa cyane kuruhu.

Ibisobanuro birambuye

Imikoreshereze: Mu nganda zitunganya ibiryo, ikoreshwa nka buffent agent, Emulsifuer, anti-caking, antioxident yongeyeho, inyongera yimirire hamwe nintangiriro yicyuma.

Gupakira: Yuzuyemo igikapu cya polyethylene nkikibaya cyimbere, hamwe nigice cya plastiki cya plastiki giboshye nkigikapu cyo hanze. Uburemere bwuburemere bwa buri mufuka ni 25 kg.

Ububiko no gutwara: Igomba kubikwa mu bubiko bwumutse kandi bwuzuyemo, yabujije ubushyuhe n'ubushuhe mugihe cyo gutwara, bidapakuruwe no kwitondera kugira ngo birinde ibyangiritse. Byongeye kandi, igomba kubikwa ukundi kuva ahantu h'uburozi.
