1, ibyokurya bigaburira amazi kugirango uhindure pH agaciro kimpamvu
Muri iki gihe, amashyiga menshi yo mu Bushinwa akoresha amazi ya rezo ya osmose cyangwa sodium ion resin guhanahana amazi yoroshye, revers osmose demineralised water cyangwa sodium ion resin guhanahana amazi yoroshye pH agaciro ni make na acide, reaction osmose yangiza amazi pH muri rusange ni 5-6, sodium ion resin guhanahana amazi yoroshye pH agaciro muri rusange ni 5.5-7.5, kugirango bikemuke kwangirika kwamazi ya acide kubiteke hamwe nu miyoboro, Dukurikije ibivugwa mubipimo ngenderwaho byigihugu BG / T1576-2008, agaciro ka pH kumashanyarazi. amazi ari hagati ya 7-9 na pH agaciro kamazi ya demineralised ari hagati ya 8-9.5, kubwibyo amazi yo guteka akeneye guhindura agaciro ka pH.
2, ihame ryibanze ryo kongeramo sodium karubone mumazi yo kugaburira amazi kugirango uhindure agaciro ka pH
Sodium karubone izwi cyane nka soda, ivu rya soda, ivu rya soda, gukaraba alkali, ishyirwa mu munyu, ntabwo ari alkali, formula ya chimique Na2CO3, mubihe bisanzwe byifu yera cyangwa umunyu mwiza.Ihame ryibanze ryo kongeramo sodium karubone mumazi yo kugaburira amazi kugirango uhindure agaciro ka pH ni ugukoresha karubone ya sodium kugirango ushonge mumazi kandi ube alkaline, ishobora gutesha agaciro karuboni ya dioxyde de mazi ya acide kandi igakemura kwangirika kwamazi yoroshye ya acide cyangwa umunyu amazi kuri boiler n'umuyoboro.Sodium karubone ni electrolyte idakomeye, yashonga mumazi kugirango ikore igisubizo cya buffer ya sodium karubone na sodium bicarbonate, hariho umunzani wa electrolytike mubisubizo, hamwe no gukoresha hydroxide ya electrolytike, uburinganire buzakomeza kugenda iburyo, bityo pH igaragara muri reaction ntabwo ihinduka cyane.
Sodium karubone yibanze ya hydrolysis:
Na2CO3 Sodium karubone + H2O amazi = NaHCO3 sodium bicarbonate + NaOH hydroxide ya NaOH
Sodium karubone ya kabiri ya hydrolysis:
NaHCO3 sodium bicarbonate + H2O amazi = H2CO3 acide karubone + NaOH sodium hydroxide
Sodium karubone yibanze ya hydrolyzed ion ingana:
(CO3) 2-aside ya karubone + H2O amazi = HCO3- bicarbonate + OH- hydroxide
Sodium karubone ya kabiri ya hydrolyzed ion ingana:
HCO3- bicarbonate + H2O amazi = H2CO3 aside karubone + OH- hydroxide
3, ihame ryibanze ryo kongeramo sodium hydroxide mumazi abira kugirango uhindure agaciro ka pH
Sodium hydroxide yitwa kandi soda ya caustic, soda ya caustic, soda ya caustic, soda ya caustic, ubusanzwe flake yera, formula ya chimique NaOH, hydroxide ya sodium ifite alkaline ikomeye, yangirika cyane.
Ionisiyoneri ya hydroxide ya sodium: NaOH = Na ++ OH-
Ongeramo hydroxide ya sodium mumazi ya boiler irashobora guhagarika firime ikingira hejuru yicyuma, kuzamura agaciro ka pH kumazi yo kugaburira amazi n'amazi yo mu itanura, kugirango bikemure kwangirika kwa acide amazi yoroshye cyangwa amazi yanduye. guteka n'umuyoboro, no kurinda ibikoresho by'icyuma kwangirika.
4. Ibyiza nibibi byo gukoresha sodium karubone cyangwa hydroxide ya sodium kugirango uhindure agaciro ka pH kumazi yo kugaburira
4.1 Umuvuduko wo kuzamura pH agaciro hamwe na sodium karubone na sodium hydroxide kumazi yo kugaburira amazi hamwe nigihe cyo gukomeza ingaruka zikoreshwa biratandukanye
Umuvuduko wo kongeramo sodium karubone mumazi yo guteka kugirango wongere agaciro pH uratinda kurenza hydroxide ya sodium.Kuberako sodium karubone itanga igisubizo cya buffer, ifite ihindagurika rito kandi irahagaze neza kandi byoroshye guhinduka.Ariko, urwego rwo guhindura pH rugarukira.Iyo uhinduye agaciro kamwe ka pH, ingano ya sodium karubone izaba nini kuruta iyo hydroxide ya sodium.Ingaruka yo gukoresha ikomeza igihe kirekire, kandi pH yamazi ntabwo yoroshye kugabanuka.
Sodium hydroxide ni base ikomeye kandi ikomeye ya electrolyte, hydroxide ya sodium kugirango ihindure pH agaciro k ihindagurika ni nini, hydroxide ya sodium nyuma yo kongeramo amazi pH biroroshye kwiyongera, guhindura agaciro ka pH byihuse kandi bitaziguye, ariko kandi biroroshye kuri guhirika ntibishobora gushyira cyane, ugereranije na sodium karubone kugirango yongereho bike irashobora kugera kubipimo bya pH bisabwa, nukuvuga, nubwo sodium hydroxide pH agaciro kiyongereye, Nyamara, ingano ya hydroxide ya sodium yiyongereye ntabwo ari nini, ni ukuvuga, ubushobozi bwamazi yo gutesha aside aside ya hydroxide ntabwo yiyongera cyane, pH izagabanuka vuba.
4.2 Ingaruka ziterwa no kongeramo cyane sodium karubone na hydroxide ya sodium kugirango byongere agaciro ka pH kumazi yo kugaburira biratandukanye
Ongeramo sodium karubone nyinshi mumazi abira kugirango uhindure agaciro ka pH bizongera umunyu wamazi yinkono hamwe nubushobozi;Hariho ion nyinshi za bicarbonate mumazi yinkono, kandi ion ya bicarbonate ibora byoroshye muri dioxyde de carbone iyo ishyushye.CO2 yinjira mu guhinduranya ubushyuhe no guhuza amazi hamwe na parike.Sodium karubone ntishobora guhindura gusa agaciro ka pH kumazi agaruka kumazi na parike ya kondensate, ariko kandi bigabanya agaciro ka pH kumyuka hamwe na kondensate, bikangiza impinduka zumuriro hamwe numuyoboro wa kondere.Impamvu ituma ioni mumazi ya kondensate yamazi arenze ibara risanzwe ryumuhondo cyangwa umutuku.
Ongeramo sodium hydroxide nyinshi mumazi yitanura kugirango uhindure agaciro ka pH bizatera amazi yinkono alkali kuba ndende cyane, kandi amazi na soda bizagaragara.Ingano ya hydroxide ya sodium ntabwo yoroshye kuyigenzura, kandi NaOH yubusa ikabije izatera alkaline nini ugereranije, kandi kwinjiza alkali nabyo bizatera kwangirika kubikoresho.Umwanditsi yabonye ikirahuri cya fibre cyongerewe imbaraga cya tanki ya plastike yuzuye ibishishwa kurubuga rwumukoresha, byononekaye kandi bisobekeranye kubera gukoresha hydroxide ya sodium kugirango igenzure agaciro ka pH y’imyanda.Hydroxide ya sodiyumu ntishobora guhindura agaciro ka pH kumazi agaruka kumazi no guhumeka, kandi ntishobora kugenzura kwangirika kwamazi ya parike hamwe na parike ya reta hamwe nibikoresho byumuyoboro.
4.3 Umutekano wa sodium karubone na sodium hydroxide ikoreshwa mumazi yo kugaburira amazi kugirango uzamure pH iratandukanye
Sodium karubone iroroshye, ni iy'ibiribwa byo mu rwego rw'ibiribwa, kubyutsa bito, kwangirika gake, bisanzwe birashobora gukorwaho n'intoki, bikenewe igihe kirekire kwambara uturindantoki.
Sodium hydroxide ni ibintu biteye akaga, byangirika, kandi igisubizo cyayo cyangwa umukungugu wamenetse ku ruhu, cyane cyane ku mucyo, birashobora kubyara ibisebe byoroshye, kandi bishobora kwinjira mu ngingo zimbitse.Gutwika bisiga inkovu.Kwisuka mu jisho, ntabwo byangiza cornea gusa, ahubwo binangiza imyenda yimbitse yijisho.Kubwibyo, uyikoresha agomba gukoresha amavuta adafite aho abogamiye na hydrophobique kuruhu, kandi agomba kwambara imyenda yakazi, masike, ibirahure birinda, uturindantoki twa reberi, feri ya reberi, inkweto ndende n’ibindi bikoresho byo kurinda umurimo kugirango akore akazi keza ko kurinda umuntu.
Hariho gukoresha no kugerageza byerekana: Sodium hydroxide na sodium karubone ikoreshwa muburyo butandukanye, cyangwa ivanze, ubukungu bwayo ningaruka zayo nibyiza kuruta gukoresha pH runaka igenga wenyine.Iyo pH agaciro k'amazi yo kugaburira amazi asanze ari make cyane, hydroxide ya sodium imwe irashobora kongerwaho muburyo bukwiye kugirango yongere vuba pH agaciro.Hydroxide ya sodium imaze gushonga burundu, karubone ya sodium irashobora kongerwamo kugirango izamure karubone mumazi.Ibi birashobora kugabanya igabanuka ryagaciro ka pH yamazi yo kugaburira;Kuberako ingano ya karubone ya sodiumi ishobora gushirwa mubindi byinshi, ubushobozi bwo kubungabunga karubone mumazi nibyinshi, mubisanzwe rero karubone ya sodium irashobora gukoreshwa kugirango igumane agaciro ka pH kumazi n'amazi y'inkono, gusa mugihe pH agaciro ka amazi ni make cyane, umwanditsi arasaba ko hakoreshwa hydroxide ya sodium kugirango yongere vuba pH agaciro, kugirango byombi bisimburwe, haba mubukungu ndetse ningaruka nziza.
