Ikarita ya Caustic Soda Ikarita

Soda ya Caustic ni iki?

Sodium hydroxide, uzwi kandi nka soda ya Caustic, soda ya Caustic, ifite imiti ya chimique nah. Nibintu bikomeye cyane, mubisanzwe muburyo bwa flake yera cyangwa granules. Irashobora kuvangwa namazi kugirango akore igisubizo cya alkaline, kandi irashobora kandi gushonga muri methanol na ethanol. Iyi miti ya alkaline irase kandi izakurura imyuka yamazi mu kirere, kimwe na mpesi ya acide nka dioxyde de carbone. Sodium hydroxide nimwe mumiti ikoreshwa. Ifite urwego runini rwa porogaramu kandi ni ngombwa mu buryo bwinshi bw'inganda: Bikoreshwa kenshi mu gukora impapuro zifunze ibiti, imyenda, amasabune nandi mashini, kandi ikoreshwa mu rugo rwo gusukura alkaline.

Nigute soda ya caustic ikozwe?

Uburyo bwinganda bukunze gukoreshwa ni electrolysis, bugabanijwemo:
◆ Diaphragm electrolysis: Nyuma yo kurahira umunyu mwinshi, ongeraho soda ash, soda ya caustic soda, na bariya banganira gukuraho umwanda nka calcium, na ontnesium, na veon. Noneho ongeraho sodium polyacrylate cyangwa yakoreshejwe brans kuri tank yo mu rwego rwo kwihutisha imvura. Nyuma yumucanga, ongeramo aside ya hydrochloric kugirango itenduke. Inyenzi irashya kandi yoherejwe muri electrolysis. Amashanyarazi arashya, ahumeka, umunyu, arakonja kugirango abone soda ya Caustic ya Caustic. Ibindi bibyimba kandi kwibanda bizabona ibicuruzwa bikomeye bya caustic soda. Gukaraba inkweto umunyu ukoreshwa mugurisha. Formulaire ya chimique: 2Nacl + 2h₂o [electrolysis] → 2naoh + cl₂↑ + h₂↑
◆ Ion Guhana uburyo bwo muri Membrane: Nyuma yumunyu wizewe umunyu, inzara iratunganya ukurikije uburyo gakondo. Urwenya rwa mbere runonosora ruhumeka binyuze muri microporous yangiriye nabi karubone ya karubone, hanyuma yongera gutunganya mu rwego rwo guhana umunara wa resin kugirango ugabanye calcium na magnesium iri muri metero 0,002%. Ibirimo kabiri byatunganijwe ni electrolyzed kugira ngo babyare chlorine mu cyumba cya Anode. Nya na + mu cyumba cyo mu cyumba cya Anade yinjiye mu Rugereko cya Cathode Binyuze muri Ion Membrane no kubyara Hydroxide hamwe na 0h mu cyumba cya Cathode. H + isohoka mu buryo butaziguye kuri Cathode kugira ngo itange hydrogen. Mugihe cya electrolyse, umubare ukwiye wa aside hydrochloric yongerewe mumujyi wa Anode kugirango mbohereze Oh- ibyo byasubijwe, kandi amazi meza asabwa agomba kongerwa mucyumba cya Cathode. Imyitozo ya Caustic ya Caustic yakozwe mu Rugereko rwa Cathode ni 30% kugeza kuri 32% (misa), ishobora gukoreshwa mu buryo butaziguye mu buryo butaziguye mu buryo bwa Caustic Soda Soda. Formulaire ya chimique: 2Nacl + 2h₂o → 2Nooh + H₂↑ + Cl₂↑

Caustic Soda hejuru y'ibicuruzwa

Umunyu wibanze: Mubisanzwe bivuga umunyu winganda winganda, nikimwe mubikoresho byingenzi bya soda ya caustic soda na soda ivu. Ibicuruzwa byayo mbisi bingana na 70% yumusaruro wuzuye wumunyu rusange.

Ibicuruzwa bisanzwe

1. Alumina: formula ya chimique al2o3. Ni uruvange rukomeye-rugoye hamwe no gushonga 2054 ° C hamwe ningingo yo kugeza 2980 ° C. Ninyamanswa na ontstal ishobora kuba ionised ku bushyuhe bwinshi kandi ikoreshwa cyane mu musaruro wa chloride ya polyiminium, mu magambo ahire, irangi, ahinduka, entixté, n'ibindi.
2. Impapuro zigwaho: ibikoresho bigize ikibaho bikozwe nimpapuro zamavurungano hamwe nimpapuro zurugomo zakozwe nabambuzi. Muri rusange bigabanijwemo impapuro imwe zigahomba hamwe nimpapuro ebyiri. Ifite ibyiza byigiciro gito, uburemere bwumucyo, gutunganya byoroshye, imbaraga nyinshi, gucapa byiza gucapa, no kubika byoroshye no gutwara. Soda ya Caustic igira uruhare rwumukozi ufasha.
3. Acide ya formatic: Acide ya formatic nimwe mubikoresho byibanze bya kama kandi bikoreshwa cyane munganda nkibyicaromoro, uruhu, dyes, imiti na reberi.

4. Bikorerwa mu nganda: ni munganda za reaction ya monoxide ya karubone na sodium hydroxide kuri 150-170 ° C hamwe na 2MPA. Mubyukuri, inzira yumusaruro wa sodium ni imwe mubyasaruro bya oxalic, kandi kwibanda kubisubizo bya sodium byakoreshwaga kubitekerezo byinjira ni 25% -30%.

5. Zirconuum oxychloride: zirconide hydroxide uburyo bwa hydrokir acide bukoresha, yongeraho aside ya aminimi , hanyuma Shaka Zirconuum Dichloride Ibicuruzwa Binyuze mu guhumeka, gukonjesha Crystallsation na Crystal Kumenagura.
