Njirimara physicochemical:
1. Colorless na transperent monoclinic prismatic crystal ma ọ bụ ọcha crystalline ntụ ntụ, odorless ma ọ bụ ubé mmanya na-esi ísì, dịtụ ilu, mfe ihu igwe na akọrọ na iru mmiri ikuku.
2. Solubility mmiri (46.5g / 100mL, 20 ℃, PH nke 0.1mol / L aqueous ngwọta bụ 8.87), acetone, wdg, soluble na ethanol, ma insoluble na ether.
3. Ebe mgbaze (℃): 324
Nchekwa
1. Chekwaa na ebe a na-emechi emechi na nkụ.
2. Ejiri akpa rọba kpuchie, akpa kpara akpa ma ọ bụ akpa egbe dị ka uwe elu. Sodium acetate bụ ihe na-adịghị mma, n'ihi ya, ekwesịrị ichebe ya na mmiri n'oge nchekwa na njem. A machibidoro iwu ịkpọtụrụ gas na-emebi emebi, gbochie ikpughe na anyanwụ na mmiri ozuzo, na ibugharị ya na mkpuchi mmiri ozuzo.
Jiri
1. Mkpebi nke ndu, zinc, aluminum, iron, cobalt, antimony, nickel na tin. Stabilizer na-agbagwoju anya. Enyemaka, ihe nchekwa, desiccant, mordant maka acetylation.
2. A na-eji achọpụta ndu, zinc, aluminum, iron, cobalt, antimony, nickel, na tin. A na-eji ya dị ka onye na-ahụ maka esterification na njikọ organic na ọtụtụ akụkụ dị ka ọgwụ foto, ọgwụ, ibipụta na agba agba, ihe nchekwa, reagents kemịkalụ, ihe nchekwa anụ, pigmenti, tanning, wdg.
3. Ejiri ya dị ka ihe nchekwa, onye na-ekpo ọkụ, onye na-ekpo ọkụ na pH regulator. Dị ka ihe na-echekwa ihe na-esi ísì ụtọ, 0.1%-0.3% nwere ike iji mee ka ísì ọjọọ kwụsị ma gbochie ngbanwe iji meziwanye ekpomeekpo. Ọ nwere mmetụta mgbochi ebu, dị ka iji 0.1%-0.3% na ngwaahịa surimi na achịcha. Ọ nwekwara ike-eji dị ka a utoojoo gị n'ụlọnga maka sizinin ihendori, sauerkraut, Mayonezi, azụ achicha, soseji, achịcha, nnyapade achicha, wdg Mixed na methyl cellulose, phosphate, wdg, na-eji melite ichebe nke sausaji, achịcha, nnyapade. achịcha, wdg.
4. A na-eji ya dị ka onye na-eme ihe na-ekpo ọkụ maka chloroprene roba na-achịkwa sọlfọ. Usoro onunu ogwu bụ n'ozuzu 0,5 akụkụ site uka. Enwere ike iji ya dị ka ihe na-emekọrịta ihe maka gluu anụmanụ.
5. Enwere ike iji ngwaahịa a tinye tin electroplating alkaline, ma ọ nweghị mmetụta doro anya na mkpuchi na usoro electroplating, ọ bụghịkwa ihe dị mkpa. A na-ejikarị sodium acetate eme ihe dị ka ihe nchekwa, dị ka acid zinc plating, alkaline tin plating na electroless nickel plating.
