Kwatanta fa'idodi da rashin amfanin amfani da sodium carbonate ko sodium hydroxide don daidaita ƙimar pH don ruwan ciyar da tukunyar jirgi

1, ruwan dafa abinci na tukunyar jirgi don daidaita ƙimar pH na dalilin

A zamanin yau, yawancin injinan dumama ruwa a China suna amfani da ruwa mai narkewar osmosis ko ruwa mai narkewar sodium ion, ruwa mai narkewar osmosis ko ruwa mai narkewar sodium ion, ruwa mai narkewar osmosis, ruwa mai narkewar osmosis, ruwa mai narkewar osmosis, ruwa mai narkewar osmosis, pH, yawanci yana da ƙasa da acidic, ƙimar pH na ruwa mai narkewar osmosis gabaɗaya shine 5-6, ƙimar pH na sodium ion, canjin ruwa mai narkewar osmosis, yawanci shine 5.5-7.5, don magance tsatsawar samar da ruwa mai tsami ga injinan dumama ruwa da bututu. Dangane da tanadin ƙa'idar ƙasa ta BG/T1576-2008, ƙimar pH na ruwan tukunyar masana'antu yana tsakanin 7-9 kuma ƙimar pH na ruwan da aka rage yana tsakanin 8-9.5, don haka samar da ruwan tukunyar yana buƙatar daidaita ƙimar pH.

2, ƙa'idar asali ta ƙara sodium carbonate a cikin ruwan dafa abinci na tukunyar jirgi don daidaita ƙimar pH

Sodium carbonate an fi saninsa da soda, soda ash, soda ash, washing alkali, wanda aka rarraba shi a matsayin gishiri, ba alkali ba, dabarar sinadarai Na2CO3, a cikin yanayi na yau da kullun don farin foda ko gishiri mai kyau. Babban ƙa'idar ƙara sodium carbonate a cikin ruwan dafa abinci na tukunya don daidaita ƙimar pH shine amfani da sodium carbonate don narke a cikin ruwa kuma ya zama alkaline, wanda zai iya kawar da carbon dioxide a cikin ruwan ciyar da acidic kuma ya magance lalata ruwan laushi na acid ko ruwan gishiri akan tukunyar jirgi da bututun. Sodium carbonate wani electrolyte ne mai rauni, wanda aka narkar a cikin ruwa don samar da maganin buffer na sodium carbonate da sodium bicarbonate, akwai daidaiton electrolytic a cikin maganin, tare da amfani da electrolytic hydroxide, ma'aunin zai ci gaba da motsawa zuwa dama, don haka pH da ke cikin amsawar ba ya canzawa sosai.

Tsarin hydrolysis na farko na sodium carbonate:

Na2CO3 Sodium carbonate +H2O ruwa = NaHCO3 sodium bicarbonate +NaOH sodium hydroxide

Tsarin hydrolysis na biyu na sodium carbonate:

NaHCO3 sodium bicarbonate +H2O ruwa =H2CO3 carbonic acid +NaOH sodium hydroxide

Lissafin ion na farko na hydrolyzed sodium carbonate:

(CO3) 2-carbonic acid +H2O ruwa =HCO3- bicarbonate +OH- hydroxide

Daidaiton ion na biyu na hydrolyzed sodium carbonate:

HCO3- bicarbonate + H2O ruwa = H2CO3 carbonic acid + OH- hydroxide

3, ƙa'idar asali ta ƙara sodium hydroxide a cikin ruwan tukunyar jirgi don daidaita ƙimar pH

Ana kuma kiran sodium hydroxide da caustic soda, caustic soda, caustic soda, caustic soda, yawanci farin flake, sinadaran NaOH, sodium hydroxide yana da ƙarfi alkaline, mai lalata sosai.

Daidaiton ionization na sodium hydroxide: NaOH=Na++OH-

Ƙara sinadarin sodium hydroxide a cikin ruwan tukunyar zai iya daidaita fim ɗin kariya da ke saman ƙarfe, inganta ƙimar pH na ruwan ciyar da tukunyar da kuma ruwan tanda, don magance tsatsawar ruwan da aka yi wa acid ko ruwan da aka lalata a kan tukunyar da bututun, da kuma kare kayan aikin ƙarfe daga tsatsa.

4. An kwatanta fa'idodi da rashin amfanin amfani da sodium carbonate ko sodium hydroxide don daidaita ƙimar pH don ruwan ciyar da tukunyar jirgi.

4.1 Saurin ƙara darajar pH tare da sodium carbonate da sodium hydroxide don ruwan dafa abinci na tukunya da lokacin kiyaye tasirin amfani ya bambanta

Saurin ƙara sodium carbonate a cikin ruwan da ke cikin tukunyar jirgi don ƙara ƙimar pH ya fi na sodium hydroxide jinkiri. Saboda sodium carbonate yana samar da maganin buffer, yana da ɗan canji kuma yana da daidaito kuma yana da sauƙin daidaitawa. Duk da haka, kewayon daidaita pH yana da iyaka. Lokacin daidaita ƙimar pH iri ɗaya, adadin sodium carbonate zai fi girma fiye da na sodium hydroxide. Ana kiyaye tasirin amfani na dogon lokaci, kuma pH na ruwan ba shi da sauƙin raguwa.

Sodium hydroxide tushe ne mai ƙarfi kuma mai ƙarfi na electrolyte, sodium hydroxide don daidaita ƙimar pH na canjin yana da girma, sodium hydroxide bayan ƙara pH na ruwa yana da sauƙin ƙaruwa, daidaita ƙimar pH da sauri da kuma kai tsaye, amma kuma yana da sauƙin kawar da shi ba zai iya sanyawa da yawa ba, idan aka kwatanta da sodium carbonate don ƙara ƙasa da haka zai iya isa ga buƙatun pH index, wato, kodayake ƙimar pH ta sodium hydroxide ta ƙaru, Duk da haka, adadin sodium hydroxide da aka ƙara ba shi da girma, wato, ikon ruwa na kawar da acid na rukunin hydroxide ba ya ƙaruwa sosai, pH zai faɗi nan ba da jimawa ba.

4.2 Illar da ke tattare da ƙara yawan sinadarin sodium carbonate da sodium hydroxide don ƙara darajar pH ga ruwan da ke ciyar da tukunya ya bambanta.

Ƙara yawan sinadarin sodium carbonate a cikin ruwan tukunya don daidaita ƙimar pH zai ƙara yawan gishirin da ke cikin ruwan tukunya da kuma yadda ake amfani da shi; Akwai ƙarin ions na bicarbonate a cikin ruwan tukunya, kuma ions na bicarbonate suna narkewa cikin sauƙi zuwa carbon dioxide lokacin da aka dumama su. CO2 yana shiga cikin na'urar musayar zafi kuma yana haɗa ruwan tare da tururi. Sodium carbonate ba wai kawai ba zai iya daidaita ƙimar pH na ruwan dawowar tururi da tururi ba, har ma yana rage ƙimar pH na tururi da condensate, yana lalata bututun musayar zafi da condensate. Dalilin da yasa ions na ƙarfe a cikin tururi ke dawo da ruwan dawowa ya wuce launin rawaya ko ja na yau da kullun.

Ƙara yawan sodium hydroxide a cikin ruwan tanda don daidaita ƙimar pH zai sa ruwan tukunya ya yi yawa, kuma ruwa da soda za su bayyana. Adadin sodium hydroxide ba shi da sauƙin sarrafawa, kuma NaOH mara yawan gaske zai haifar da babban alkalinity, kuma lalacewar alkali shima zai haifar da tsatsa ga kayan aikin. Marubucin ya ga tankin cire filastik mai ƙarfi da aka cika da faci a wurin mai amfani, wanda ya lalace kuma ya huda saboda amfani da sodium hydroxide don daidaita ƙimar pH na debrine. Sodium hydroxide ba zai iya daidaita ƙimar pH na tururi da tururi ba, kuma ba zai iya sarrafa tsatsa na kayan aikin dawo da tururi da tururi da tsarin samar da ruwa da hanyar sadarwa ta bututu ba.

4.3 Tsaron sodium carbonate da sodium hydroxide da ake amfani da su a cikin ruwan dafa abinci don ƙara darajar pH ya bambanta.

Sodium carbonate yana da ɗan laushi, yana cikin kayan abinci, ƙaramin abin ƙarfafawa, ɗan tsatsa, ana iya taɓa shi da hannu, buƙatar saka safar hannu na dogon lokaci.

Sodium hydroxide abu ne mai haɗari, mai lalata fata, kuma maganinsa ko ƙurar da aka fesa a fata, musamman a kan mucous membrane, na iya haifar da ƙura mai laushi, kuma yana iya shiga cikin kyallen takarda masu zurfi.
