Yangzhou Interbright Chemical CO.LTD.

Caustic soda piritsi rudzi rwechiratidzo chechiSoda

Zvakasiyana kwazvo. Kushandiswa kwakawanda kweCaustic mahwendefa ezvipata anopfupikiswa seinotevera:

1, Pepa:

Papermaking zvinhu zvimedu zvehuni kana huswa zvidyarwa, zvidyarwa zveuswa mukuwedzera cellulose, asi zvakare chine huwandu hwakawanda husina-cellulose (lignin, gamu, nezvimwewo). Flake Alkali anoshandiswa kudiwa, uye iyo fiber inogona chete kuwanikwa nekubvisa lignin kubva kune huni. Iyo isiri-cellulose chikamu chinogona kuvhiringidzwa nekuwedzera dilute caustic solution solution, saka iyo cellulose sechinhu chikuru chePulp inogona kugadzirira.

2, Yakanatswa Petroleum:

Mushure mekunge zvigadzirwa zvepamhepo zvakashambwa neslfuric acid, zvimwe zvinhu zvemukati zvinofanirwa kushambidzwa ne piritsi alkali solution, uye washambwa kuti uwane zvigadzirwa zvakanatswa.

3. Textile:

Cotton uye machira emachira anobatwa neyakaomeswa sodium hydroxide (caustic soda) mhinduro yekuvandudza fiber zvivakwa. Kubhururuka kwemafuta akadai seyakajaira machira, Rayon, etcose machira (anoitwa soda), carpon soda (cs2) seyakagadzirwa, yakagadzirwa neViscose, nekuita svutugadzike, nekupururudza.

4, Kudhinda nekuchengetera:

Cotton mucheka weAlkaline Solution kurapwa, kunogona kubvisa yakafukidzwa muCotton Fabric wax, mafuta, strar

5, kugadzira sipo:

Chikamu chikuru chesipo ndiyo sodium munyu wevakuru vane mafuta ecids, kazhinji yakagadzirwa nemafuta eaya uye alkali seaini seyakagadzirwa kuburikidza neSaponification maitiro. Kuwedzera kune yakakwira mafuta acid salts, sipo zvakare ine rosin, girazi remvura, zvinonhuwira, dhayi uye mamwe mafirita. Zvakarongeka, iyo yakakwirira mafuta acid sodium ine isina-polar hydrophobic chikamu (hydrocarbon boka) uye hydrophilic chikamu (carboxyl group). Boka reHydrophobic rine Oleophilic Properties. Munguva yekugeza, iyo mafuta mune tsvina inovhunduka uye yakapararira madonhwe emarara, uye mushure mekusangana neboka remafuta. Iyo hydrophic group (carboxyl group), iyo inopenya nyore nyore mumvura, inotambanudzwa kunze kwekunze kwekudonha kwemafuta uye yakaiswa mumvura. Chinhu chikuru chinonyudzwa sipo ndiNao, asi naOoh haasi soko. Mhinduro yayo yemvura ine mafuta uye inogona kushandiswa sesipo. Soap ndeye emulsifier. Iyo nheyo ndiyo SAPONICIED Reaction ch3co0ch2ch3 + naoh = chit3coona + ch3ch2oh, and ch3coona ndiyo inoshanda inoshanda muSap.

6, indasitiri yemakemikari:

Gadzira sodium yesimbi, mvura yemagetsi ndeye kushandisa mahwendefa eAlkali. Kugadzirwa kwemazhinji madzinza emukati, kunyanya kugadzirira kweimwe sodium saltts (sodium sidium, sodium dichromite, sodium sulfa, etc.) inoshandiswa muchiratidziro alkali. Iyo inoshandiswawo mu synthesis yemadhirowa, zvinodhaka uye organc vepakati.

7, Indasitiri yeMaRemalurgical:

Kazhinji kushandura chikamu chinoshanda cheguva muzvinyorwa zvekunyaradza munyu, kuti abvise kusachena kwehungwaru, saka, kazhinji kunoda kuwedzera mahwendefa eAlkali. Semuenzaniso, mukupfira maitiro ealuminium, kugadzirira kwaCryolite uye kurapwa kweBauxite anoshandiswa.

8, kushandiswa kwe lime kuvandudza ivhu:

Muvhu, nekuti nyaya organic muchiitiko chechiodhisheni chinoburitsa organic acids, mamiriro ekunze emaminerari anogona zvakare kuburitsa zvakare zvinhu zvakanaka. Uye zvakare, kushandiswa kweiyo inorganic fettilizer yakadai saAmmonium Sulfate, Ammonium chloride, etc., ichaitawo ivhu acidic. Kushandisa huwandu hwakaringana hwemberi hunogona kusimudzira iyo acid muvhu, ita kuti ivhu rive rakakodzera kukura kwegopi, uye kusimudzira nhema dzehutachiona. Mushure mekukuvara kweCA2 + muvhu, kunogona kusimudzira kutenderwa kwevhu revhu, iyo inokodzera kuumbwa kwekuunganidzwa, uye panguva imwe chete, inogona kupa iyo kaunzi inodikanwa yekukura kwechirimwa.

9. Alumina Production:

Naoh Solution inotsvakwa kuti isimbe Alumina muBauxite uye kuwana sodium aluminAte mhinduro. Mushure mekunge mhinduro yacho yaparadzaniswa Mhinduro yacho mushure mekunyepedzera kweAluminium Hydroxide inonzi Amai doro, iyo yakavhurwa uye yakabviswa uye yakaiswa uye yakagadzirwazve. Nekuda kweiyo yakasiyana crystalline zvivakwa zveDiaspore, diaspore uye diaspore, yavo solubility muCaustic Soluda yakasiyana, saka inodikanwa kupa mamiriro akasiyana-siyana ekupaza, kunyanya kupisa kwakasiyana kwekupaza. Iyo diaspore mhando bauxite inogona kunyimwa pa125 ~ 140c, uye iyo diaspore mhando inogona kunyimwa pa 240 ~ 260 ℃ uye yekuwedzera ye lime (3 ~ 7%).

10, ceramics:

Caustic svutugadzike mune yeCeramic inogadzira gadzira ine mapoinzi maviri: Kutanga, mukupfura maitiro eCeramics, caustic soda se dhilient. Chechipiri, pamusoro peiyo yakadzivirirwa ceramic ichave yakakwenenzverwa kana kuomarara, uye mushure mekuchenesa neCaustic Soluda Solution, iyo Ceramic Surch ichave inotsvedza.

11, Kusafarira:

hutachiona hwehutachiona. Izvi zvinonyanya kushandiswa kuitira kuchenesa uye kusatadza mabhodhoro muindasitiri yewaini.

12 Kuwedzera kumarara:

Simba sodium oxide kuti rigadzirise iyo PH kukosha, kurapwa kwesewge, kuitira kuti zviwanikwa zvichikwanisika.

13, gadziriro yemakemikari, maindasitiri ekumaindasitiri:

Piritsi alkali inonyanya kushandiswa muindasitiri yemishonga yekugadzirisa mhinduro kana kugadzirisa iyo pH kukosha kwemishonga yemishonga.

14, Electroplating, tungsten Kunatsa .:

Mahwendefa eAlkali ari mumatare ari kusimbisa semhedzisiro yemagetsi, tora basa reConstlet!

15, Silk silika, gadzira rayon machira.

16. Indasitiri yeganda (Sumo yeyishandisirwo yemapiritsi maviri eAlkali):

.

Pakati pematanho maviri eLime Powder inobata kurapwa, kushandiswa kwe30% Sodium Hydroxide Solution
. Mushure mekukurudzira, wedzera hydrochloric acid mune trickle, ramba uchimutsa kwemaminetsi makumi maviri kusvika makumi matatu, uye wedzera fomu re formaldehyde mvura. Ichengete inodziya

17, Indasitiri yePolyters Chemical:

Inoshandiswa kugadzirwa kweiyo fomu (oxal acid, borax, sodium cyanide neshizha, synthetic fatty acids, synthetic decant, nezvimwe.

18, machira ekudhinda uye indasitiri yekudyira:

Inoshandiswa sekotoni inoda mumiririri, anodzika mumiririri, kungwara mumiririri uye kuderedza dhayi, haichang bhuruu dhayi.

19, Inonhuwirira Indasitiri:

yaishandiswa kugadzira aluminium hydroxide, aluminium oxide uye simbi sosi yekurapa mumiririri.

20, indasitiri yechigadzirwa ,:

Inoshandiswa seAcid Neutralizer, jegerizing mumiririri, leodorizing mumiririri.

21, Adhesives Indasitiri:

yakashandiswa sehuni dzeGealhinger, kusarerekera.

22, Mugadziri Phosphate, Gadzira Mhananate.

23. Kugadziriswazve kwekare rabha.

24, inogona kushandiswa seCitrus, Peach Peeling Agent uye Concorrizing Mumiririri, Deodorant.

25, Piritsi alkali rinoshandiswawo mukugadzira pestical.
