Chemical Properties |
Raws li lub hauv paus muaj zog thiab tsis muaj zog acid ntsev, dej qab zib tshauv tuaj yeem hydrolyze hauv cov tshuaj aqueous los tsim hydroxide ions, nthuav tawm muaj zog alkalinity. | Kuj tseem muaj ntsev, ci dej qab zib nthuav tawm tsis muaj zog alkalinity hauv cov kua dej vim nws qhov qis qis ntawm kev sib cais hauv dej, khaws qee cov hydrogen ions hauv cov molecule. | ||
Lub cev muaj zog |
Qhov tshwm sim: zoo, hmoov dawb nrog cov xim dawb huv Solubility: heev soluble nyob rau hauv dej, tsim ib tug alkaline tov. Thermal stability: ua kom pom kev thermal stability ntau dua, ruaj khov txawm tias nyob rau hauv cov cua kub kub. |
Qhov tshwm sim: zoo, dawb crystalline khoom zoo li zoo ntsev Solubility: solubility cuam tshuam los ntawm qhov kub thiab txias, soluble hauv dej siab tshaj 50 degree. Thermal stability: decomposes raws li cua sov los tsim carbon dioxide, dej, thiab sodium carbonate. |

Kev siv thiab cuam tshuam |
Cov ntawv thov kev lag luam: Dav siv nyob rau hauv iav manufacturing, textile printing thiab dyeing, thiab raws li ib tug raw khoom rau ua lwm yam sodium tebchaw. Kev ua zaub mov: Siv los ua tus neeg sawv cev nruab nrab lossis cov neeg sawv cev tawm, txawm tias tus nqi yuav tsum tau tswj kom tsis txhob cuam tshuam rau cov zaub mov saj thiab kev nyab xeeb. Ntxuav: Ua hauj lwm hauv kev lag luam tu txheej txheem vim nws alkalinity. |
Ci: Ua hauj lwm raws li ib tug leavening neeg sawv cev nyob rau hauv ci qhob cij, ncuav, thiab lwm yam khoom noj, ua rau lawv softer thiab qab dua. Kev tu tsev: Siv kev nyab xeeb thiab ib puag ncig los ua lub tshuab ntxuav tais diav, lauj kaub, thiab lwm yam khoom siv hauv tsev. Kev siv tshuaj: Muaj peev xwm neutralize plab acid kom txo tau gastric tsis xis nyob. Lwm yam kev siv: Siv los ua cov dej haus carbonated, ua cov tshuaj tua hluav taws, thiab tshem tawm cov ntxhiab tsw. |

Kev xav txog kev nyab xeeb |
Vim nws muaj zog alkalinity, dej qab zib tshauv tuaj yeem ua rau tawv nqaij thiab qhov muag. Yog li ntawd, cov khoom siv tiv thaiv xws li khaub ncaws, hnab looj tes, tsom iav, thiab qhov ncauj qhov ntswg yuav tsum tau hnav thaum siv. Cov dej khib nyiab uas muaj dej qab ntsev yuav tsum tau kho kom zoo kom tsis txhob muaj kuab paug ib puag ncig. |
Feem ntau suav hais tias muaj kev nyab xeeb rau kev siv hauv tsev, tab sis kev noj ntau dhau tuaj yeem ua rau tsis xis nyob. | ||
