1, boiler ba fepa metsi ho fetola boleng ba ph ea lebaka
Matsatsing ana, batho ba bangata ka China sebelisa basse basmosis ba songoang ka makhetlo a 5-6, boleng ba sodium. Rarolla khara ea metsi a acid ea acidic ho ea re apereng liaparo le lipeipi, ho latela lipehelo tsa metsi a bophelo ba naha e pakeng tsa 8-9.5, kahoo phepelo ea metsi ea boilent e hloka ho fetola boleng ba PH.
2, molao-motheo oa mantlha oa ho eketsa sodium carbonate ho boiler ho fepa metsi ho lokisa boleng ba PH
Sodium Carbonate o tsejoa e le Alkali, a khetholla Alkali, eseng Alkali, Climam Foramlama Na2CO3, letsoai le tloaelehileng bakeng sa phofo e tšoeu kapa letsoai le letle. Molao-motheo oa mantlha oa ho eketsa sodium carbonate ho ea pherekano ea Ph e ka sebelisa metsi a acid acid a ka fokotsang metsi kapa metsi a letsoai kateng le pompoline. Sodium Carbonate ke e motlakase e fokolang, e qhibiliha metsing ho etsa tharollo ea buffer, ka hona ph e teng ha u ikutloa joalo.
Sodium carbonate ea khokahanyo ea sodium hydrolysis:
Navco3 sodium carbonate + H2O Metsi a metsi = Nahco3 sodium bicarbonate + Naoh sodium hydroxide
Sodium carbonate ea bobeli ea hydrolysis:
Nahco3 sodium bicarbonate + H2O Metsi = H2CO3 Carbonic Acid + Naoh sodium hydroxide
Sodium Carbonate ea mantlha ea Ion:
(Co3) 2-carbonic acid + h2o metsi = hc3- bicarbonate + oh- hydroxide
Sodium Carbonate Secondary Secondarter Equation:
HCO3- Bicarbonate + H2O Metsi = H2CO3 Carbonic Acid + Oh-hydroxide
3, molao-motheo oa mantlha oa ho eketsa sodium hydroxide ho ea metsi a boiler ho fetola boleng ba ph
Sodium hydroxide e boetse e bitsoa cada, caday soda, sodium soda, sodium sodake e nang le alkaline e matla, e benyang haholo.
Equation equation equation ea sodium hydroxide: Naht = Na ++ oh-
Ho eketsa sodium hydroxide ho metsi a boilear a ka tiisa filimi e sirelletsang holim'a metsi, e le metsi a entsoeng ka seboko, e be metsi a entsoeng ka seboko.
4. Melemo le likotsi tsa ho sebelisa sodium carbonate kapa sodium hydroxide ho fetola boleng ba PH hore metsi a feptjoa
4.1 Lebelo la ho holisa boleng ba PH le sodium carbonate le sodium hydroxide bakeng sa boiler ea boiler, ka nako ea ho boloka tšebeliso e fapane
Lebelo la ho eketsa sodium carbonate ho phepelo ea metsi a boilert ea boilert ho eketsa boleng ba PH e lieha ho feta ea sodium hydroxide. Hobane sodium carbonate o hlahisa tharollo e nyane ea buffer, e na le khatello e nyane ebile e bonolo ho e fetola. Leha ho le joalo, mefuta ea phetoho ea ph e lekantsoe. Ha u ntse u fetola boleng bo ts'oanang, palo ea carbonate ea sodi e tla ba kholo ho feta ea Sodium hydroxide. Phello ea tšebeliso e bolokoa nako e telele, 'me PHO ea metsi ha e bonolo ho e tlohela.
Sodium hydroxide ke setsi se matla le sesebelisoa se matla sa motlakase, sodium hydroxide Boleng ba Pydroxide bo ile ba eketseha, sodium hydroxide ba ekelitse, ke hore, bokhoni ba metsi ho khelosa acid ea amdroxide.
4.2 Kotsi e bakiloeng ke tlatsetso e feteletseng ea sodium carbonate le sodium hydroxide ho eketsa boleng ba ph bakeng sa metsi a phefumoloho a fapaneng
Ho eketsa sodium e ngata haholo ka metsing a boiler ea boiler ho fetola boleng ba pH ho eketsa sejo sa metsi le boitšoarona; Ho na le li-bicarbonate li na le li-bicarbonate ka metsing, 'me lihlekehleke tse bicarbonate li lahleloa habonolo ke khabone dioxide ha e futhumatsa. CO2 e kenya marang-rang a mocheso le metsi a mangata ka mouoane. Sodium Carbonate ha a khone ho fetola boleng ba PH feela ho khutlisa metsi a Steam le Steam. Lebaka le etsang hore tšepe ea tšepe e leng metsi a khutlang ea Steam e feta 'mala o tloaelehileng kapa' mala o mofubelu.
Ho eketsa sodium e ngata haholo metsing a boea ho lokisa boleng ba pH ho tla ba holimo haholo, mme metsi le soda li tla hlaha. Palo ea sodium hydroxide ha ho bonolo ho laola, le hang hang hang, hang hang a baka lalkarinirini e kholo, mme Alkali Sengoli se bone fiber ea polasetiki e matla e tletse likonopo sebakeng sa mosebelisi, e neng e entsoe hape ka lebaka la ts'ebeliso ea likoloto tsa phdium. Sodium hydroxide ha a khone ho fetola boleng ba PH le metsi a khutlang a ho khutla le ho se khone ho khutla
4.3 Ts'ireletso ea sodium carbonate le sodium hydroxide e sebelisitsoeng ho boiler ho jala boleng ho phahamisa boleng ba PH bo fapane
Sodium Carbonate e bonolo haholo, e le thepa e nyane, e tloaelehileng, e ka ikutloa e lokela ho roala liatlana.
Sodium hydroxide ke lisebelisoa tse kotsi, lijalo tsa eona kapa lerōle la eona, li ka hlahisa lisele tse bonolo, 'me li ka kenella lisele tse tebileng. Ho chesa ho siea letlalo. Ho pharalla ka leihlo, ha se senya mofuta oa Cornea, empa o boetse o senya lisele tse tebileng tsa leihlo. Ka hona, opareire e lokela ho sebetsa setlolo se sa nke lehlakore letlalong, mme o tlameha ho roala liaparo, likhalase tse sirelletsang, litlolo tse telele tsa rabara, li-rabara tse ling ho etsa mosebetsi o motle oa ts'ireletso ea motho.
Ho na le linyeoe tse sebelisoang le ho leka tse bonts'a: Sodium Syadroxide le sodium carbonate e sebelisoa ka mokhoa o fapaneng, kapa moruo o molemo ho feta o sebelisa mohokahanyi ea itseng a le mong. Ha boleng ba boileparo sa boiles bo fumanoa bo nyahame haholo, sodium hydroxide e ka eketsoa ka nepo ho eketsa boleng ba PH. Kamora hore cydroxide e felisitsoe ka botlalo, mosirebe o mong oa khapo o ka eketsoa ho holisa carbonate ka metsing. Sena se ka nolofalletsa ho theoha ha boleng ba metsi a phepelo; Hobane palo ea carbonate ea sodium e ka kenngoa ka ho feta, bokhoni ba ho boloka likhakanyo tsa boikhathollo bo tlase haholo, e le hore tse peli li behiloe hantle, ka bobeli.
