Mapa a Caustic Soda

Kodi caustic soda ndi chiyani?

Sodium hydroxide, imadziwikanso kuti caustic soda ndi caustic soda, ili ndi mankhwala a Naoh. Ndi malo okhalamo kwambiri, nthawi zambiri ngati mawonekedwe a ma flakes oyera kapena granules. Itha kusakanizidwa ndi madzi kuti apange yankho la alkalinine, ndipo amathanso kusungunuka ku Methanol ndi Mowa. Zinthu zamchereyi ndi zotchipa ndipo zimamwa mpweya wamadzi m'mwamba, komanso mpweya wa acidic monga kaboni dayokisi. Sodium hydroxide ndi amodzi mwa mankhwala omwe nthawi zambiri amagwiritsa ntchito. Ili ndi ntchito zingapo ndipo ndizofunikira pakupanga mafakitale ambiri: nthawi zambiri imagwiritsidwa ntchito popanga mapepala a plagp, zolembedwa, sopo ndi zotupa zina, ndipo zimagwiritsidwanso ntchito munyumba ya alkaline yoyeretsa zinthu.

Kodi causda imapangidwa bwanji?

Njira yogwiritsidwa ntchito kwambiri yogwiritsidwa ntchito kwambiri ndi electrolysis, yomwe imagawidwa:
Ma diaphragm electrolysis: Pambuyo pa mchere wamchere wam'wina, onjezerani phulusa la koloko, ndipo barus soda, ndi barum chloride yochotsa zonyansa monga calcium, magnesium, ndi mphamvu yamphamvu. Kenako onjezerani sodium polyacrytete kapena kugwa china chogwera ku tank yovomerezeka kuti mufulumizire kuthamanga. Pambuyo pa mchenga wamchere, onjezani hydrochloric acid kusiya. Brine amakonzedwa ndikutumizidwa ku Elevolysis. Electrolyte amasandukanso, anapanduka, mchere, ndi utakhazikika kuti apeze soda sous. Kuchulukitsa komanso kukhazikika kumapeza zolimba zolimba za koloko. Mafuta amchere amasamba amagwiritsidwa ntchito popanga mchere. Micula ya Chemical: 2h₂o [electrolysis] → 2Nooh + p₂ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑
◆ Mchere wa Membrane: Pambuyo pa mchere wawisa umathiridwa mchere, brine amatsutsidwa molingana ndi njira yachikhalidwe. Brine woyengedwa woyamba umasefedwa kudzera mu seweroli la microctore stal tufala, kenako ndikuyezanso kudzera mu kusinthana kwa ion kumachepetsa calcium ndi magnesium omwe ali pansipa 0.002%. Brine woyengeka wachiwiri ndiwopangidwa matchulidwe kuti atulutse chlorine mu chipinda cha sode. A Nani + mu brine m'bali m'chipinda chokhazikika cholowa m'chipinda cha cakadade kudzera pa ion. H + imatulutsidwa mwachindunji pa cast Cast to amapanga hydrogen. Panjira ya electroly, kuchuluka kwa ma hydrochloric okwanira kumawonjezeredwa ku malo osungiramo malo kuti asachite kanthu, ndipo amabwezedwa, ndipo madzi oyera amayenera kuwonjezeredwa ku Catchade Chamber. Kukhazikika kwa cuassity distated soda yopangidwa mu chipinda cha cathode ndi 30% mpaka 32% (misa), yomwe imatha kugwiritsidwa ntchito mwachindunji ngati soustic mankhwala, kapena itha kukhala yokhazikika kuti ithe kupeza mankhwala omaliza a caustic. Miyezo ya mankhwala: 2Nacl + 2h₂o → 5Nooh + H₂ ↑ ↑ ↑ ↑ ₂

Caustic soda pamwamba

Mchere wa wiya: nthawi zambiri amatanthauza mchere wambiri, womwe ndi chimodzi mwazinthu zofunikira kwambiri za caustic soda ndi soda. Maakaunti amtundu wake wophika wa 70% ya kupanga misandu yonse ya pachaka.

Zogulitsa wamba

1. Alumina: Micula Formula Al2o3. Ndiwolimba kwambiri ndi malo osungunuka 2054 ° C ndi malo otentha a 2980 ° C. Ndi ion kristal yomwe imatha kuvomerezedwa kutentha kwambiri ndipo imagwiritsidwa ntchito kwambiri popanga polyilumium chloride, aluminium sulfate, utoto wa utoto, encrete utoto.
2. Pepala lotetezedwa: malo owoneka bwino opangidwa ndi pepala la osanja mwapamwamba opangidwa ndi ogudubuza. Nthawi zambiri amagawidwa m'mapepala amodzi otetezedwa ndi pepala lokhazikika. Ili ndi maubwino a mtengo wotsika mtengo, kunenepa kwambiri, kukonza kosavuta, mphamvu yayikulu, yosindikiza yosindikiza, ndi kusungidwa kosavuta, komanso kusungidwa kosavuta. Custic Soda imakonda kukhala ndi othandizira opanga mapepala.
3.

4. Wopanga sodium M'malo mwake, kupanga kwa sodium ndi gawo limodzi la kupanga kwa oxalic acid, ndipo kupsinjika kwa sodium hydroxide njira yomwe imagwiritsira ntchito mayamwidwe ndi 25% -30%.

5. Zirconium oxychloride: Kupukusa koloko yosungunuka, kenako ndikuchotsa ma aciric acid kuti apeze Zirconium Oxchloride , kenako pepani Zirconium dichloride pogwiritsa ntchito Evaporation ndende, yozizira crystallization ndi kuphwanya kwa galasi.
