Urwego rwo gusaba no gukoresha sodium hydroxide

YANGZHOU EVERBRIGHT CHEMICAL CO.LTD.

Ibinini bya soda ya Caustic ni ubwoko bwa soda ya caustic, izina rya chimique sodium hydroxide, ni alkali ishonga, yangirika cyane, irashobora gukoreshwa nka aside itabangamira aside, hamwe na masking agent, imvura igwa, imiti igabanya imvura, umukozi wibara, saponification agent, peeling agent, detergent n'ibindi

Biratandukanye cyane.Gukoresha ibinini bya soda ya caustic byavuzwe muburyo bukurikira:

1, gukora impapuro:

gukora impapuro mbisi ni ibiti cyangwa ibyatsi, ibyo bimera usibye selile, ariko kandi birimo umubare utari muto wa selile (lignin, gum, nibindi).Flake alkali ikoreshwa mugusobanura, kandi fibre irashobora kuboneka mugukuraho lignine mubiti.Ibice bitari selile birashobora gushonga wongeyeho umuti wa soda ya caustic soda, kugirango selile nkibice byingenzi bigize pulp irashobora gutegurwa.

2, peteroli inoze:

Ibicuruzwa bya peteroli bimaze gukaraba hamwe na acide sulfurike, ibintu bimwe na bimwe bya acide bigomba gukaraba hamwe nigisubizo cya alkali, hanyuma ukakaraba kugirango ubone ibicuruzwa byiza.

3. Imyenda:

imyenda y'ipamba n'ibitambara bivurwa hamwe na sodium hydroxide yibanze (soda caustic) kugirango bitezimbere fibre.Fibre artificiel nka pamba yubukorikori, ubwoya bwubukorikori, rayon, nibindi, ahanini ni fibre ya viscose, ikozwe muri selile (nka pulp), soda ya caustic, karubone disulfide (CS2) nkibikoresho fatizo, bikozwe muri viscose, mukuzunguruka, umwirondoro.

4, gucapa no gusiga irangi:

umwenda w'ipamba hamwe no kuvura umuti wa alkaline, urashobora gukuramo utwikiriye ibishashara by'ipamba, amavuta, ibinyamisogwe nibindi bintu, mugihe wongeyeho ibara rya mercerisation yigitambara, kugirango irangi risa.

5, gukora isabune:

igice kinini cyisabune ni umunyu wa sodium ya acide ya acide yateye imbere, ubusanzwe ikozwe mumavuta hamwe na tableti ya alkali nkibikoresho fatizo binyuze muri saponification reaction.Usibye umunyu mwinshi wa aside irike, isabune irimo rosine, ikirahuri cyamazi, ibirungo, amarangi nibindi byuzuza.Mu buryo bwubaka, sodium ya aside irike irimo igice cya hydrophobique idafite polar (hydrocarbon group) hamwe na hydrophilique polar (groupe carboxyl).Itsinda rya hydrophobique rifite imiterere ya oleophilique.Mugihe cyo gukaraba, amavuta mumwanda arakangurwa hanyuma akwirakwizwa mubitonyanga bito byamavuta, hanyuma nyuma yo guhura nisabune, itsinda rya hydrophobique (hydrocarbon group) ya molekile ya sodium ya acide nyinshi yinjizwa mumatonyanga yamavuta, kandi molekile zamavuta zirimo guhambirwa hamwe n'ingabo za van der Waals.Itsinda rya hydrophilique (itsinda rya carboxyl), ryashonga byoroshye mumazi, ryagurwa hanze yigitonyanga cyamavuta hanyuma ryinjizwa mumazi.Ibyingenzi byingenzi byisabune ni NaOH, ariko NaOH ntabwo isabune.Igisubizo cyacyo cyamazi ni amavuta kandi arashobora gukoreshwa nkisabune.Isabune ni emulifier.Ihame nigisubizo cya saponification CH3CO0CH2CH3 + NaOH = CH3COONa + CH3CH2OH, naho CH3COONa nikintu gikora mubisabune.

6, inganda z’imiti:

kora sodium yicyuma, amazi ya electrolytike agomba gukoresha ibinini bya alkali.Umusaruro wumunyu mwinshi udasanzwe, cyane cyane gutegura imyunyu ya sodiumi (nka borax, sodium silike, sodium fosifate, sodium dichromate, sodium sulfite, nibindi) bikoreshwa muri tablet alkali.Irakoreshwa kandi muguhuza amarangi, ibiyobyabwenge hamwe nabahuza.

7, inganda z'ibyuma:

kenshi kugirango uhindure ibintu bikora byamabuye mumunyu wa sodium ya elegitoronike, kugirango ukureho umwanda udashonga, kubwibyo, akenshi ukenera kongeramo ibinini bya alkali.Kurugero, mugikorwa cyo gushonga cya aluminium, hategurwa cryolite no kuvura bauxite.

8, gukoresha lime kugirango utezimbere ubutaka ：

mu butaka, kubera ko ibinyabuzima bigenda byangirika bizabyara aside irike, ikirere cy’amabuye y'agaciro nacyo gishobora kubyara aside.Byongeye kandi, gukoresha ifumbire mvaruganda nka ammonium sulfate, ammonium chloride, nibindi, bizanatuma ubutaka bwa acide.Gukoresha urugero rwiza rwa lime birashobora guhindura aside mu butaka, bigatuma ubutaka bukwiranye no gukura kw ibihingwa, kandi bigatera ikwirakwizwa rya mikorobe.Nyuma yo kwiyongera kwa Ca2 + mu butaka, irashobora guteza imbere kwegeranya ubutaka bwa koleoide, ifasha mu gukora igiteranyo, kandi icyarimwe, irashobora gutanga calcium ikenewe mu mikurire y’ibihingwa.

9. Umusaruro wa Alumina:

NaOH igisubizo gishyushye kugirango ushongeshe alumina muri bauxite no kubona sodium aluminkurya igisubizo.Nyuma yuko igisubizo gitandukanijwe nibisigara (icyondo gitukura), ubushyuhe buragabanuka, hydroxide ya aluminiyumu yongerwaho nkimbuto ya kirisiti, nyuma yigihe kinini cyo gukurura, sodium aluminate ibora muri hydroxide ya aluminium, ikakaraba, ikabarwa kuri 950 ~ 1200 ℃ , okiside ya aluminiyumu yarangije kuboneka.Igisubizo nyuma yimvura ya hydroxide ya aluminium yitwa inzoga ya nyina, ihumeka kandi igahundagurika kandi ikongera gukoreshwa.Bitewe nuburyo butandukanye bwa kristalline ya diaspore, diaspore na diaspore, gukemura kwayo mumuti wa soda ya caustic biratandukanye cyane, birakenewe rero gutanga ibihe bitandukanye byo gusesa, cyane cyane ubushyuhe butandukanye bwo gushonga.Ubwoko bwa diaspore bauxite burashobora gushonga kuri 125 ~ 140C, kandi ubwoko bwa diaspore bauxite burashobora gushonga kuri 240 ~ 260 ℃ no kongeramo lime (3 ~ 7%).

10, ububumbyi:

soda ya caustic mubikorwa byo gukora ceramic ifite ingingo ebyiri: icya mbere, mugikorwa cyo kurasa ceramika, soda ya caustic nka diluent.Icya kabiri, ubuso bwa ceramique bwarashwe buzashushanywa cyangwa bukabije, kandi nyuma yo koza hamwe numuti wa soda wa caustic, ubuso bwa ceramic buzaba bworoshye.

11, kwanduza:

virusi ya poroteyine.Ibi bikoreshwa cyane mugusukura no kwanduza amacupa muruganda rwa vino.

12, usibye amazi mabi:

okiside ikomeye ya sodium kugirango ihindure agaciro ka ph, gutunganya imyanda, kugirango umutungo ukoreshwe.

13, imyiteguro yimiti, inyongeramusaruro ：

Ibinini bya alkali bikoreshwa cyane mubikorwa bya farumasi kugirango bahindure ibisubizo cyangwa bahindure pH agaciro k ibisubizo byimiti.

14, amashanyarazi, gutunganya tungsten .：

Ibinini bya alkali mubisahani nkibisubizo bya electroplating, kina uruhare rwumuyobora!

15, gukora silik, gukora ipamba ya rayon.

16. Inganda zimpu (Intangiriro yuburyo bubiri bwo gukoresha ibinini bya alkali) ：

.

Hagati yintambwe ebyiri zo kuvura ifu ya lime, gukoresha 30% sodium hydroxide yumuti hamwe nuburemere bwa tare 0.3-0.5% byongerewe kugirango fibre yuruhu yagure byuzuye kugirango byuzuze ibisabwa kandi bitezimbere ubwiza bwibicuruzwa byarangiye.
. gushonga rwose.Nyuma yo gukurura, ongeramo aside hydrochloric mumazi, komeza ukangure muminota 20 kugeza 30, hanyuma wongeremo amata y'amazi ya fordehide.Komeza gushyuha kuri 78 ~ 80 ℃, yemerera gukora muminota 40 ~ 50, ongeramo 10% ya sodium hydroxide ya sodium yo kubogama, kuyikonjesha kugeza kuri 60 ~ 70 ℃, hanyuma ongeramo formula urea yo kuvura amino, hanyuma uyungurure igisubizo cya kole unyuze murushundura kugirango ukoreshwe.

17, uruganda rukora imiti ya polyester ：

ikoreshwa mugukora acide formique, acide oxyde, borax, fenol, sodium cyanide nisabune, acide fatty acide, detergent synter, nibindi.
