Chii chinonzi caustic soda?
Sodium Hydroxide, inozivikanwawo seCousic soda uye caustic soda, ine yemakemikari mafomula noh. Iyo inonyanya kuora chigadziko chakasimba, kazhinji muchimiro chemuchena mapopoma kana granules. Inogona kusanganiswa nemvura kuti ugadzire iyo alkaline solution, uye inogona zvakare kunyungudika methanol uye ethanol. Iyi alkaline chinhu ndeye maune uye ichatora mvura yemvura mumhepo, pamwe nemagasi emazwi akadai secarbon dioxide. Sodium hydroxide ndeimwe yemakemikari anowanzoshandiswa. Iyo ine huwandu hwakawanda hwekushandisa uye chinhu chinodiwa muzvikamu zvakawanda maindasitiri: zvinowanzoshandiswa mugadziri wehuni pepa, zvidimbu, masoja uye zvimwe zvinoshandiswa mune zveimba alkaline dhiraini zvigadzirwa zvekuchenesa zvigadzirwa zvekuchenesa zvigadzirwa zvekuchenesa zvigadzirwa zvekuchenesa.
Caustic yakagadzirwa sei?
Iyo inonyanya kushandiswa kushandiswa kwemaindasitiri nzira magetsi, ayo akapatsanurwa mu:
◆ Dhiafragm Eleadrolysis: Wedzera Soda Ash, Caustic Soda, uye Cautic Clomini Wobva wawedzera sodium polyacrylate kana causticised bran kune kujekesa tangi kuti ukure precipitation. Mushure mejecha faira, wedzera hydrochloric acid kuti dzisarare. Brine inodiwa uye inotumirwa kune electrolysis. MaEkista electroly anga ada, akaputika, akakwiridzwa, uye akatonhorera kuti awane mvura yechikepe. Kuwedzera kugombedzera uye kusvinura kuchawana iyo yakasimba caustic soda chigadzirwa. Matope emunyu yekushambidza mvura inoshandiswa pakukwazisa. Makemikari formula: 2nacl + 2h₂o [Electrolys] → 2naoh + cl₂↑ + H₂↑
◆ ion exchange mmbrane nzira: Mushure mekunge munyu wakasviba wakarungwa, brine inonatswa maererano nenzira yechinyakare. Brine yekutanga yakanatswa yakanatswa kuburikidza neyekukutu kabhoni tubon tubon filter, uye yakazonatswa zvakare kuburikidza nekucheka Ion exin todzerwe muBrine neBrine kusvika pazasi 0.002%. Brine yechipiri yakanatswa yakasarudzwa kuti igadzire chlorine mune yeAyodwe chamber. NA + muBrine muAnode mukamuri inopinda mukamuri yeCathode kuburikidza neIon membrane uye inogadzira sodium hydroxide ne 0h mukamuri yekati. Iyo H + inobviswa zvakananga pane iyo cathode kuti iite hydrogen. Munguva yemagetsi maitiro, huwandu hwakakodzera hwekunyora-kwehydity hydrochloric acid inowedzerwa kuAnody Iko kusvinuka kweiyo yakakwira-yakanyanya caustic soda yakagadzirwa muCathode Chamber Chamber Caustic chigadzirwa soda chigadzirwa, kana chinogona kuenderera mberi nekuwana chigadzirwa chakapera cheCaustic soda. Cemical formula: 2nacl + 2h₂o → 2naoh + h₂↑ + cl₂↑
Caustic soda yakakwira zvigadzirwa
RAW SALE: Kazhinji inoreva maindasitiri emunun'una Yayo rakabikwa munyu unonamata maakaundi 70% yehuwandu hwegore negore raw rova muromo.
Zvakajairika Kupfuura Zvigadzirwa Zvigadzirwa
1. Alumina: makemikari formula al2o3. Iyo yakakwirira-yakaoma nzvimbo ine chekunyungudika nzvimbo ye2054 ° C uye nzvimbo inovira ye 2980 ° c. Icho chidimbu chechiwi chinogona kuve chakavanzika pakukwirira kwakanyanya uye zvinoshandiswa zvakanyanya mukugadzirwa kwePolandauminium chloride, aluminium sulfate, pendi pigment, kongiri admixture, nezvimwe
2 Iyo inowanzo kukamurwa kuita imwe chete yakagadziridzwa mapepa ePaphiboard uye mbiri dzakarukwa mapepa. Izvo zvine zvakanakira mutengo wakaderera, uremu hwakareruka, kugadzirisa zviri nyore, simba rakanyanya, rekudhinda rakanakisa rekudhinda, uye kuchengetedza nekuchengetera uye kufambisa. Caustic soda inotora basa remapepa emuxilialar mumiririri.
3. Apic acid: Yemafananidzo Acid ndechimwe chezvinhu zvekutanga zvemakemikari zvidzitiro uye zvinoshandiswa zvakanyanya mumaindasitiri akadai semishonga yekuuraya zvipuka, dehwe, mishonga, mishonga uye rabha.
4. Sodium fomu: Iyo inogadzirwa neyunivhesiti nekuita kabhoni monoxide uye Sodium hydroxide pa150-170 ° C uye nezve 2mpa. Muchokwadi, maitiro ekugadzira eSodium exicate chikamu chekugadzirwa kwe oxalic acid, uye kusunganidzwa kweiyo sodium hydroxide solution inoshandiswa kuitwa kweiyo 25% -30%.
5. Zirconium Oxychloride: The Zirconium Hydroxic Hydrochloric Acdrochel Nzira yekunyungudika, svina shuwa Oxychloride, uye wobva wawana zirconium dichloride chigadzirwa kuburikidza nekuvhura kwevachechi, kutonhora crystallization uye kuchema kupwanywa.
