Sodium hydroxide, hangata e tsejoang e le Cada, Alkali e behileng haholo ka mofuta oa li-slakes, granules kapa lithunya. E qhibiliha habonolo ka metsing (e lokolla mocheso ha e qhalana ka metsing) ebe e etsa tharollo ea alkaline. Ha u ka monya chelete ea metsi habonolo (ka boomo) le carbon dioxide (ho senyeha) moeeng. Hydrochloric acid e ka eketsoa ho lekola hore na e senyehile. Ho qhoma habonolo habonolo metsing, Ethanol le Glycerol, empa o khathatsa Acetone le Ether. Sehlahisoa se hloekileng ke kristale e se nang 'mala le e pepesang. TLHOKOMELISO 2.13G / CM3. Potso ea Melisa 318 ℃. NOLARTIT 1388 ℃. Lihlahisoa tsa indasteri li na le sodium chloride chloride le sodium carbonate, eo e leng likristale tse tšoeu tsa opaque. Ha re bue ka likopo tse sebetsang tsa likopo tsa sodium hydroxide ka kalafo ea kalafo ea tšepe.
1. Bakeng sa ho tlosa oli Ha khatello ea sodium hydroxide e fokotseha 'me ph e ka tlase ho 10.5, sodium Sterate e tla fokotsoa' me phello ea ho tlosa oli e tla fokotsoa; Haeba mahloriso a phahame haholo, solubility ea sodium Sterate le ho feta tse tla fokotsoa Tekanyetso ea Sodium ka kakaretso ha e felle 100g / l. Sodium hydroxide e sebelisoa haholo likarolong tsa tšepe, tse kang likarolo tse fapaneng, li-nickel, koporo, joalo ka likhoele tsa polasetiki, bakeng sa likhoele pele. Leha ho le joalo, sodium hydroxide ha ea lokela ho sebelisoa likarolo tsa tšepe tsa tšepe tse sa fetoheng joalo ka aluminium le zinc. ALKALINE DisReaning ea likarolo tsa polasetiki e loketse ea ABS, Ponosulfone, e fetotsoeng Ponolic e joalo ka lithahasello tsa khalase ha li tšoanelehe bakeng sa alkaline.
2. Sesebelisoa sa ho emisa ka tšepe ①. Ha a phekola Aluminium Alloy Mokhoa ona ke mokhoa o tloaelehileng oa kalafo pele aluminium alloy oxidation. Palo e kholo ea sodium hydroxide e boetse e sebelisetsoa ho ba le li-achinum tsenyori tsa aluminium aney. ②. Sodium hydroxide ke thepa e bohlokoa ea ho itlotsa ka mokhoa o ikhethileng ts'ebetsong ea aluminium le aloys. Hape ke mokhoa o tloaelehileng oa ho ba o benyang kajeno. Ts'ebetsong ea etching ea aluminium le e abelang, litaba tsa sodium hydroxide hangata li laoloa ka 100 ~ 200g / l. , e le khatello ea sodium hydroxide e eketseha, lebelo la ho hlahisa lebelo le potlakisang. Leha ho le joalo, haeba ho tsepamisa mohopolo ho le holimo haholo, e tla eketsa theko. Boleng ba thepa e ts'oanang ba lisebelisoa tse ling tsa aluminium li mpefala. Reaction e atalelang Ai +Ho = Naaio2 + H2 ↑
3. Ka likopo tsa lipelaelo tsa electroplating le tsa lik'hemik'hale, sodium hydroxide e sebelisoa ho alkaline tin plating le alkaline Zinc plating. Haholo-holo ho Alkaline Zinc ho plating, sodium hydroxide ke boemo ba mantlha ba ho boloka botsitso ba tharollo; Ho hlakile ho elektrone ho sebelisitsoe bakeng sa phetoho ea pH ea kopi ea koporo e se nang motlakase; E sebelisoa bakeng sa ho hlophisoa ha tharollo ea ho qoelisoa pele aluminium alloyum allowste / electroplating, jj. ①. Sebetsa ho Cyaanze Zinc e plating. Sodium hydroxide ke moemeli e mong ea ratoang ka bateng ea ho beha. E ea mehara e nang le zinc Ion ho etsa li-Ions tsa Zincate, tse tsitsitseng le ho feta li ntlafatsang tsa ho hlapela. Ka hona, litloaelo tsa ts'ebetso ea hajoale tsa ho qhalana ha hona joale le bokhoni ba ho senyeha ha tharollo ea plats li ntlafala. Ha litaba tsa sodium hydroxide li phahame, hoode e qhibiliha ka potlako, e etsa hore li-zin li sebetse ka tharollo ea zinc ka tharollo ea ho qala le ho koaheloa ho ba thata. Haeba khoele ea sodium e tlase haholo, phepelo ea tharollo ea plats e fosahetse, ts'ebetso ea hona joale ea fokotseha, 'me koluoa e tla ba e bohloko. Tharollo ea ho bapala tse se nang sodium hydroxide, katleho ea cashde e tlaase haholo. Ha le khatello ea sodium hydroxide e eketseha, maqhubu a cathode butle-butle a eketseha butle butle. Ha leqhubu la sodium hydroxide e fihla tekanyo e itseng (e joalo ka 80g / l), katleho ea temthode e fihlella boleng bo holimo ka morao ho nako eo. ②. Ho sebetsa ho Zincate Fertroplating: Sodium hydroxide ke moemeli ea rarahaneng oa letsoai le letsoai le tsamaisang. Ho fetella ka mokhoa o fokolang oa sodium hydroxide ho ka tiisa haholoanyane ebile o na le boitšoaro bo betere, bo molemo ho ntlafatsa bokhoni ba ho hana ha ho se hloekise. , mme o lumelle amoutu hore e qhibilihe ka tsela e tloaelehileng. Karolelano ea boima ba zinc oxide ho sodium hydroxide ka tharollo ea zincate e ka bang 1: (10 ~ 14) Ha litaba tsa sodium hydroxide li phahame haholo, ho tsepamisa maikutlo ha zinc sethkeng ho phahame haholo, 'me crystallization ea koae e lerootho. Haeba litaba li le tlaase haholo, phepelo ea ho hlapela ea ho bapala e etsoa habonolo, e amang boleng ba koae. ③. Kopo ho alkaline tin plating. Ka Alkaline tin plating, ts'ebetso ea mantlha ea sodium hydroxide e tla theha letsoai le tsitsitseng le letsoai, ho ntlafatsa monyebe le ho nolofatsa ho felisoa ha anade. Ha le khatello ea sodium hydroxide e eketseha, likotloriria li fetoha matla le bokhoni ba ho senyehe, empa ho sebetsa hona joale hoa fokotseha. Haeba sodium hydroxide e phahame haholo, ho thata hore Aduese e be le boemo bo fetisitsoeng habonolo, 'me e qhibiliha boleng bo rarollotsoeng. Ka hona, ho laola mokhoa oa ho laola sodium hydroxide ho feta bohlokoa haholo ho feta ho laola letsoai le letsoai la Tin. Hangata ea sodium hydroxide e laoloa ho 7 ~ 15g / l, 'me haeba potasiamo hydroxide e sebelisoa, e laoloa ho 10 ~ 20g / l. Ka har'a alkaline ea ho tšoaha e se nang motlakase, sodium hydroxide e sebelisoa haholo ho lokisa boleng ba ph, boloka botsitso ba tharollo bakeng sa formalsehde. Tlas'a maemo a itseng, ho eketsa mahloriso a sodium hydroxide ka nepo ho eketsa lebelo la litefiso tsa koporo, empa ho e-na le ho nahana haholo ka ho tsitsa ha tharollo ea likepe tse se nang motlakase. Sodium hydroxide e boetse e sebelisoa haholo ka holim'a sekheo sa tšepe. Khatello ea Sodium hydroxide ka kotloloho e ama lebelo la oxida le axida. STEF-Carbon Sense e na le lebelo le potlakileng la oxidation le mahloriso a tlase (550 ~ 650g / l) li ka sebelisoa. Khoeli ea tšepe e tlase-carbon lebelo le liehang le e phahameng (600 ~ 00g / l) e ka sebelisoa. Ha khatello ea sodium hydroxide e phahame, filimi ea pompo e boreleli, empa sephara sa lifilimi se boreleli ebile se le lerootho, 'me lerōle le khubelu le tloaetse ho hlaha. Haeba khatello ea sudium hydroxide e feta 1100g / l, magnetic tšepe ea tšepe e qhibiliha ebile ha e khone ho theha filimi. Khatello ea Sodium Hydroxide Haeba e le tlase haholo, filimi ea oxide e tla ba tšesaane ebile sebaka se sirelletsang se tla ba futsaneha.
