Sodium hydroxide, mubisanzwe izwi nka soda ya Caustic, Soda yumuriro, na soda ya caustic cyane muburyo bwa flake, granules, cyangwa ibice. Birashonje byoroshye mumazi (birekura ubushyuhe iyo bushonga mumazi) kandi ikora igisubizo cya alkaline. Nibishobora kandi birashobora gukuramo imyuka y'amazi (penquescence) na dioxyde de carbone (kwangirika) mu kirere. Acide ya hydrochloric irashobora kongerwaho kugirango agenzure niba yangiritse. Byoroshye gushonga mumazi, ethanol, na glycerol, ariko udashidikanya muri acetone na ether. Ibicuruzwa byera ni ibara ritagira ibara kandi ryumucyo. Ubucucike 2.13g / CM3. Gushonga Ingingo 318 ℃. Ingingo yo guteka 1388 ℃. Ibicuruzwa byinganda birimo bike bya chloride ya sodium na sodium karubone, aribyo kristu ya ovaque. Reka tuganire kubisabwa bya sodium hydroxide muburyo bwo kuvura ibyuma.
1. Kuraho gukuramo amavuta, koresha sodium hydroxide kugirango ubyitwaramo acide yuzuye mu nyamaswa no gutanga sodium yoroheje ya sodium yamamaza (isabune (glycerin (glycerin (glycerin (glycerin (glycerin (glycerin (glycerin (glycerin (glycerin (glycerin (glycerin (glycerin (glycerin (glycerin (glycerin (glycerin). Iyo kwibanda kuri sodium hydroxide na ph iri munsi ya 10.5, sodium ihungabanye izahinduka hydrolyzed kandi ingaruka zo gukurwaho amavuta zizagabanuka; Niba kwibanda cyane, kukesha sodium yihuta kandi hazagabanuka, bizagabanuka, bikaviramo kwamazi mazi nabi na hydrogan okledation. Umuyoboro wa sodium muri rusange ntirurenga 100g / l. Sodium hydroxide ikoreshwa cyane mubice by'icyuma, nk'ibimera bitandukanye, Titanium alloys, Nickel, umuringa, n'ibice bidafite iby'icyuma, kugira ngo bigabanye mbere yo kwifotoza. Nyamara, sodium hydroxide ntigomba gukoreshwa kuri degrease alkali-ikomantasha ibyuma nka alumini na zinc. Alkaline defreasing yibice bya plastike birakwiriye ab, polysulfone, yahinduwe polystyrene, nibindi biruka byikirahure byashimangiwe nibisubizo bya alkaline ntibikwiriye kuri debreasing alkaline.
2. Ibyuma bya Etching Porogaramu ①. Mu kuvura aluminium alloy mbere yuko okiside, umubare munini wa sodium hydroxide ukoreshwa kuri alkali esching. Ubu buryo nuburyo busanzwe bwo kuvura mbere ya Aluminium Asloy okiside. Umubare munini wa sodium wasaga nawo ukoreshwa kuri aluminium alloy yerekana. ②. Sodium hydroxide nigikoresho cyingenzi cyo kugata kubintu bya ething ya aluminium na alloys. Nubu buryo busanzwe bwo kuhama. Muburyo bwa EUMINUM na Alloys, ibikubiye muri sodium hydroxide igenzurwa muri rusange kuri 100 ~ 200g / l. , kandi nkuko kwibanda kuri sodium hydroxide yiyongera, umuvuduko wihuta wihuta. Ariko, niba kwibanda cyane, bizamura ikiguzi. ETCHING ubuziranenge bwibikoresho bimwe na bimwe byahumuriza. Igisubizo ni gukurikira ai + naoh + h2o = naaio2 + h2 ↑
3. Muri Electraplating na Porogaramu Zishimwe Zitanga Amashanyarazi, Amashanyarazi manini akoreshwa muri polkaline tin na alkaline zinc. Cyane cyane muri alkaline zinc, ingano ihagije ya sodigide nigikorwa cyibanze cyo gukomeza umutekano; Mubyifuzo bya electroless bikoreshwa kuri pH guhindura plaper idafite amashanyarazi; Byakoreshejwe mugutegura igisubizo cya zinc kwibiza mbere ya aluminium alyloy elegitale idafite amatora / electroplating, nibindi. ①. Gusaba muri Cyanide zinc. Sodium hydroxide nundi mukozi utoroshye mugutanga. Ibigoye hamwe na zinc onte ions ions, ituma iryo ryo kwiyuhagira rihamye kandi ritezimbere imikorere yo kwiyuhagira. Kubwibyo, Cathode imikorere yubushobozi kandi itandukanya igisubizo cyo gukwirakwiza iratera imbere. Iyo sodium ikubiyemo isuku iri hejuru, anode irashonga byihuse, itera ibikubiye muri zinc mu gisubizo cyo kwiyongera kwiyongera no gufunga kugirango bikomere. Niba sodium hydroxide iri hasi cyane, imikorere yicyorezo gikennye, imikorere iriho ubungubu, kandi igikombe nacyo kizaba kibi. Mu gisubizo cyo gushushanya kidakubiyemo sodium hydroxide, imikorere ya Cathode iri hasi cyane. Mugihe kwibanda kuri sodium hydroxide, imikorere ya Cathode iriyongera buhoro buhoro. Iyo kwibanda kuri sodium hydroxide igera kumafaranga runaka (nka 80G / L), imikorere ya Cathode igera kumugaragaro kandi igakomeza guhora nyuma. ②. Gusaba muri Zincate Electraplating: Sodium hydroxide numukozi utoroshye numunyu uyobora. Kurenga kwa sodium hydroxide birashobora gutuma intunga zitoroshye kandi zifite akamaro keza, zingirakamaro kugirango utezimbere ubushobozi bwo gutatanya. , kandi wemerere anode gushonga bisanzwe. Ikigereranyo kinini cya kinc of zinc of mexide kuri sodium hydroxide mu gisubizo cya Zincate cyakozwe neza kuri 1: (10 ~ 14), hamwe numupaka wo hasi wo gumanika no hejuru ya barrel. Iyo sodium hydroxide iri hejuru cyane, anode irashonga vuba, kwibanda kuri kinc ions muburyo bwo kwiyuhagira ni hejuru cyane, kandi kristu yo kwisiga irakabije. Niba ibirimo bitoroshye cyane, kuyobora kwiyuhagira byagabanutse, kandi imvura ya zinc hydroxide ikorwa byoroshye, igira ingaruka kumiterere yimpimbano. ③. Gusaba muri alkaline tin. Muri post ya alkaline tin, imikorere nyamukuru ya sodium hydroxide ni ugukora ikintu gihamye gifite umunyu wamabati, kunoza imirongo, kandi byorohereza iseswa risanzwe rya anode. Mugihe kwibanda kuri sodium hydroxide, harakomera kandi ubushobozi bwo gutatanya bwiyongera, ariko imikorere yubu iragabanuka. Niba sodium hydroxide ari ndende cyane, biragoye kuri anode gukomeza leta ya pasiporo ya pasiporo hamwe na shoxves yashonga amabati, bivamo ireme ribi. Kubwibyo, kugenzura kwibanda kuri sodium hydroxide ni ngombwa cyane kuruta kugenzura iminyu yumunyu. Mubisanzwe sodium hydroxide igenzurwa kuri 7 ~ 15G / L, kandi niba hydroxide ya potasiyumu ikoreshwa, igenzurwa na 10 ~ 20g / l. Mubikorwa bya alkaline bidasubirwaho, sodiyumu yakoreshejwe cyane cyane muguhindura agaciro p p ph igisubizo, komeza igicuruzwa gihamye kandi gitanga ibidukikije bya alkaline kubigabanya Formaldehyde. Mubihe bimwe na bimwe, kongera kwibanda kuri sodium hydroxide birashobora kongera umuvuduko wububiko bwa etalless, ariko hejuru cyane yibanda ku muvuduko wo kubitsa umuringa, ariko ahubwo bizagabanya umuvuduko wo gukemura amashanyarazi. Sodium hydroxide nayo ikoreshwa cyane muburyo bwibyuma. Kwibanda kuri sodium hydroxide bigira ingaruka kumuvuduko wa okiside. Ibyuma byinshi bya karubone bifite umuvuduko wihuse hamwe nigitekerezo cyo hepfo (550 ~ 650g / l) kirashobora gukoreshwa. Icyuma-carbone okiside umuvuduko ni buhoro kandi hejuru (600 ~ 00g / l) birashobora gukoreshwa. Iyo kwibanda kuri sodium hydroxide ari hejuru, filime ya oxide irabyimbye, ariko urwego rwa firime ntiruranje kandi rufite umukungugu utukura ugaragara. Niba kwibanda kuri sodium hydroxide irenze 1100g / l, magnetic chagnedide ishonga kandi ntishobora gukora firime. Kwibanda kuri sodium hydroxide niba ari hasi cyane, firime ya oxide izaba inanutse kandi ubuso buzaba bumeze neza, kandi imikorere ikingira izaba ikenerwa.
4. Gusaba kuvura imyanda: Sodium hydroxide nigice gikunze gukoreshwa mu mategeko no kwinjiza ihuza rya mail kumazi yamazi asohoka muri electraplating, anoding, nibindi.
