Kev taw qhia luv luv ntawm Caustic Soda Manufacturing Plant
Caustic dej qab zibyog ib tug muaj zog alkali nrog muaj zog corrosiveness. Nws yog feem ntau nyob rau hauv daim ntawv ntawm flakes los yog blocks. Nws yooj yim soluble hauv dej (exothermic thaum yaj hauv dej) thiab tsim cov tshuaj alkaline. Nws kuj yog deliquescent thiab yooj yim rau nqus tau pa. Dej vapor (deliquescent) thiab carbon dioxide (deterioration) tuaj yeem muab ntxiv rau hydrochloric acid los kuaj xyuas qhov tsis zoo.
NaOH yog ib qho ntawm cov tshuaj nyob rau hauv chemical Laboratory thiab ib qho ntawm cov tshuaj lom neeg. Cov khoom ntshiab yog cov xim tsis muaj xim thiab pob tshab. Qhov ceev yog 2.130 g / cm3. 318.4 ° C melting point. Qhov kub ntawm qhov kub yog 1390 ° C. Cov khoom lag luam muaj cov sodium chloride thiab sodium carbonate me me thiab yog cov dawb opaque crystals. Muaj cov blocks, flakes, granules thiab rods. Tus nqi yog 39.997.
Caustic soda manufacturing cog tuaj yeem siv los ua tus neeg saib xyuas alkaline hauv kev kho dej, soluble hauv ethanol thiab glycerin; insoluble nyob rau hauv propanol thiab ether. Disproportionation cov tshuaj tiv thaiv nrog halogens xws li chlorine, bromine thiab iodine. Nws neutralizes nrog acids tsim ntsev thiab dej.
Caustic Soda Manufacturing PlantTechnology Taw Qhia:
Lub ionic membrane caustic soda tshuab peb muab yog qhov siab tshaj plaws hauv lub ntiaj teb, tam sim no lub peev xwm peb muab yog los ntawm 2, 000t / y mus rau 320, 000t / y.
ASIA CHEMICALtuaj yeem muab cov kev ua tau zoo thiab ruaj khov Soda Ash Production Process Machinery nrog rau kev tsim qauv engineering, khoom siv, kev teeb tsa & erection kev pabcuam, kev cob qhia thiab kev pabcuam, thiab lwm yam.
Kev siv thiab ntau npaum li cas ntawm caustic soda
Ntxiv dej rau dilute los yog dissolve caustic soda, thiab npaj 1 feem pua ~ 2 feem pua caustic soda tov rau tshuaj tsuag thiab tshuaj tua kab mob. Nws yog tsuas yog siv rau kev tua kab mob ntawm cov tsiaj nyeg tsev thiab tsheb.
Lub hom phiaj tseem ceeb:
1. Cov xab npum dav dav yog acetate ntawm cov roj fatty acid ntau dua, uas feem ntau yog npaj los ntawm kev siv cov roj zaub los tsim cov tshuaj xab npum hauv qab cov nyhuv ntawm sodium hydroxide ntau me ntsis.
2. Hauv kev luam ntawv thiab dyeing factories thiab paj rwb textiles, ntau cov tshuaj caustic soda yog siv los tshem tawm cov roj zaub los ntawm cov paj rwb ntshiab, wool wool, thiab lwm yam. Sodium hydroxide tseem yuav tsum tau tsim cov fibers hluavtaws.
3. Sodium hydroxide kuj yog siv rau cov roj av tshwj xeeb. Yuav kom tshem tawm cov collagen fibers nyob rau hauv cov roj crude feem, sulfuric acid feem ntau yog ntxiv rau cov roj crude feem kom yaj cov collagen fibers rau hauv acid residues. Tom qab pickling thiab passivation, cov roj crude tseem muaj cov kua qaub thiab alkaline residues xws li phenol thiab naphthenic acid thiab nws cov tsis tsim nyog hydrochloric acid. Nws yuav tsum tau ntxuav nrog caustic soda tov thiab tom qab ntawd ntxuav nrog dej kom tau txais cov khoom siv roj av tshwj xeeb.
4. Hauv kev lag luam ntawv, thawj qhov kev daws teeb meem yog siv cov organic chemistry, steaming raw cov ntaub ntawv nrog methyl cellulose thiab organic chemicals los ua daim ntawv pulp. Txhawm rau muab nws bluntly, alkaline papermaking yog siv caustic soda tov raws li cov kua distillation kom tshem tawm lignocellulose, carbohydrate compounds thiab epoxy resins nyob rau hauv cov ntaub ntawv raw, thiab neutralize citric acid nyob rau hauv nws, thiaj li hais tias methylcellulose raug rho tawm. .
5. Hauv kev lag luam hlau thiab hlau, cov khoom siv hauv cov hlau ore feem ntau yog hloov mus rau hauv soluble acetate los pab txhawb kev tshem tawm cov residues insoluble. Yog li ntawd, feem ntau yuav tsum tau ntxiv sodium hydroxide.
6. Hauv kev lag luam tshuaj, sodium hydroxide yuav tsum tau siv los ua cov hlau sodium thiab electrolyzed dej. Kev tsim cov carbonates ntau, tshwj xeeb tshaj yog kev npaj ntawm qee cov acetates, yuav tsum siv sodium hydroxide. Sodium hydroxide kuj tseem siv rau hauv kev sib txuas ntawm dyes, kws tshuaj thiab lawv cov organic chemical intermediates.
