1, alkalization:Sodium Bicarbonate Lotion yog alkaline, tuaj yeem nruab nrab acidic tshuaj, nce cov nqi pH hauv qab, ua si lub luag haujlwm ntawm lub luag haujlwm. Qhov no tseem ceeb lub luag haujlwm hauv kev yaug thiab nruab nrab ntawm qee cov kua qaub tsis sib xws, acid hlawv, lossis cov kua qaub.

2, kev tu thiab yaug:Sodium Bicarbonate Lotion tuaj yeem siv los ntxuav thiab yaug qhov txhab, cov txhab lossis lwm thaj chaw tsis huv. Nws tuaj yeem pab tshem tawm cov av, cov kab mob, cov toxins thiab lwm cov tshuaj muaj kuab lom, txhawb kev kho kom zoo thiab txo kev pheej hmoo kis tus kab mob.

3, cov nyhuv tua kab mob:Vim nws cov khoom alkaline, sodium bicarbonate lotion tuaj yeem muab cov nyhuv ntawm cov kabmob tshuaj tua kabmob, thiab muaj cov kab mob uas muaj txiaj ntsig ntawm qee cov kab mob thiab cov kab mob. Ib qho ntxiv, sodium bicarbonate lotion tuaj yeem ua lub luag haujlwm hauv kev ua kom muaj txiaj ntsig lossis tswj cov yeeb tshuaj los txhim kho lawv qhov ruaj khov.

Dyeing ntxiv

Nws tuaj yeem siv los kho tus neeg sawv cev rau dyeing printing, acid-alkali tsis, thiab them tus neeg sawv cev rau cov ntaub txaij thiab xov. Ntxiv cov nqaij soda rau qhov dyeing tuaj yeem tiv thaiv cov xov paj los ntawm kev ua cov paj dawb.

Tus neeg saib xyuas xoob (cov khoom noj qib)

Nyob rau hauv kev ua zaub mov noj, sodium bicarbonate yog ib qho ntawm feem ntau cov khoom noj khoom haus cov khoom noj khoom haus, tab sis tom qab qhov kev ua zaub mov noj ntau dhau thiab tom qab qhov tsw qab, tab sis tom qab qhov tsw qab, tab sis tom qab qhov khoom noj tsw qab heev thiab ua rau cov tsw phem, daj xim av xim. Nws yog tus tsim cov roj carbon dioxide hauv cov dej qab zib; Nws tuaj yeem ua ke nrog Alum los ua alkaline baking hmoov, thiab tseem tuaj yeem ua ke nrog dej qab zib ua ke ua pob zeb alkali. Nws kuj tseem siv tau ua cov butter txuag. Hauv kev ua zaub ua zaub tuaj yeem siv tau los ua cov txiv hmab txiv ntoo thiab zaub ua ntej tiv thaiv tus neeg sawv cev. Ntxiv li 0.1% rau 0.2% sodium bicarbonate thaum cov zaub ntxhua khaub noom thiab zaub tuaj yeem ua rau ntsuab ruaj khov. Thaum sodium bicarbonate yog siv los ua txiv hmab txiv ntoo thiab zaub kom tau nce, cov nqaij hlwb tuaj yeem ua tau softened, thiab lub tsev ua haujlwm qub, thiab lub hnub qub uas tuaj yeem ua kom yaj. Ib qho ntxiv, nws muaj cov txiaj ntsig ntawm kev tshem cov ntxhiab tsw ntawm cov yaj mis nyuj, thiab cov nyiaj siv yog 0.001% mus rau 0.002%.
