I-Trisodium phosphate

Igama leekhemikhali: I-Trisodium phosphate

Ifomula yemolekyuli: N / A₃Po₄,N / A₃Po₄· · H₂Kwi₃Po₄· 12h₂O

Ubunzima bemolekyuli: Amandla: 163.94; I-Monohydrate: 181.96; Dodecahhyddrate: 380.18

I-CAS: Amandla: 7601-51-5-9; Dodecahhyddrate: 10101-89-0-0-0

Umlinganiswa: Yinto engenamibala okanye emhlophe, umgubo okanye i-crystalline granule. Yinto engekhoyo, inyibilika ngokulula emanzini kodwa i-insulafle kwisinyibilikisi sendalo. I-dodecahhdrate iphulukana onke amanzi amakristal kwaye i-anhydddy xa inyuka iqondo lobushushu ukuya kwi-212 ℃. Isisombululo yi-alkaline, i-corrosion encinci kulusu.

Iinkcukacha zemveliso

Ukusetyenziswa: Kumzi-mveliso wokulungisa ukutya, isetyenziswa njengearhente ye-byffsive, iarhente ye-anti-canking, i-antioximant yongezwa, isongezelelo sesondlo kunye nearhente yensimbi.

Ukupakisha: Igxunyekwe kwingxowa yePolythylene njengomaleko wangaphakathi, kunye nengxowa yeplastiki yeplastiki efana ne-suint yangaphandle. Ubunzima bomnayi webhegi nganye yi-25kg.

Ukugcina kunye nezothutho: Ifanele igcinwe kwindawo yokugcina impahla eyomileyo nengaphezulu, igcinwe kude nobushushu kunye nokufuma ngexesha lokuhamba, ukungalayishwa ngononophelo ukuze kuthintelwe ukonakala. Ngapha koko, kufuneka igcinwe ngokwahlukeneyo kwizinto ezinetyhefu.
