sodium hydrosulfide yog ib qho khoom siv tshuaj lom neeg tseem ceeb thiab cov khoom lag luam, thiab nws cov txheej txheem evaporation thiab concentration ntsib cov teeb meem tshwj xeeb xws li corrosiveness muaj zog thiab thermal rhiab heev.
Kev Tshawb Fawb Txog Cov Yam Ntxwv Tshwj Xeeb ntawm Cov Txheej Txheem Sodium Hydrosulfide Evaporation
Qhov kev ua kom cov kua sodium hydrosulfide evaporation txawv ntawm cov ntsev ib txwm muaj, feem ntau yog ob qho: cov khoom siv thiab cov txheej txheem xav tau.
Hauv kev siv tshuaj lom neeg, sodium hydrosulfide yooj yim hydrolyzes ntawm qhov kub siab, tsim cov roj hydrogen sulfide thiab sodium hydroxide. Qhov kev tshuaj tiv thaiv no tsis yog tsuas yog ua rau poob cov khoom xyaw nquag xwb tab sis kuj ua rau cov khoom siv xeb heev. Cov ntaub ntawv sim qhia tau hais tias tus nqi hydrolysis ntawm sodium hydrosulfide nce exponentially thaum qhov kub tshaj 80 ° C, xav tau kev tswj hwm qhov kub ua haujlwm hauv lub kaw lus evaporation.
Lub cev, cov tshuaj sodium hydrosulfide yog alkaline heev thiab corrosive heev, ua rau muaj kev cai nruj rau cov khoom siv. Cov hlau tsis xeb ib txwm muaj kev xeb pitting thiab kev ntxhov siab corrosion cracking tom qab kev sib cuag ntev, ua rau yuav tsum tau siv cov alloys tshwj xeeb lossis cov thev naus laus zis hauv daim ntaub. Lub caij no, cov sulfide ions hauv cov tshuaj react nrog cov hlau nto los tsim ib txheej FeS xoob, ua rau corrosion sai dua. Cov ntaub ntawv ua haujlwm qhia tau hais tias lub neej ua haujlwm ntawm cov khoom siv carbon steel tsis muaj kev tiv thaiv hauv ib puag ncig sodium hydrosulfide feem ntau tsis pub tshaj 6 lub hlis.
Cov yam ntxwv ntawm cov tshuaj sodium hydrosulfide muaj xws li: qhov kub ntawm 15-25 ° C rau 30% concentration; tus nqi xeb ntawm 0.5-2.0 hli / xyoo rau 316L stainless hlau ntawm 80 ° C; tus nqi hydrolysis ntawm 3-8% ib teev ntawm 90 ° C nyob rau hauv atmospheric siab; thiab qhov kub crystallization ntawm 40-60 ° C rau cov tshuaj saturated.
