Ingabe i-Phosphoric acid iyingozi kubantu?

Iyini i- Phosphoric acid?

I-Phosphoric acid noma i-orthophosphoric acid, i-asidi evamile ye-inorganic, iyi-asidi eqinile emaphakathi.

I-Phosphoric acid noma i-orthophosphoric acid, i-asidi evamile ye-inorganic, iyi-acid eqinile ephakathi.I-Phosphoric acid isetshenziswa ikakhulukazi emikhakheni yezemithi, ukudla, umanyolo nezinye izimboni, okuhlanganisa njenge-ejenti yokumelana nokugqwala, izithasiselo zokudla, ukuhlinzwa kwamazinyo kanye namathambo, ama-preservatives e-EDIC, ama-electrolyte, ama-welding, i-industrial competer fertilizer kanye ne-preservant imikhiqizo.Ingasetshenziswa futhi njenge-reagent yamakhemikhali.

Ingabe i-Phosphoric acid iphephile kumthengi?

I-Phosphoric acid iphephile ukuthi ingadliwa ngaphandle uma i-Phosphoric acid ithinta iso nesikhumba.

Ukuhogela: Akulindelekile ukuthi kube yingozi yokuhogela ngaphandle uma kushisa noma kunenkungu. Ingacasula ikhala nomphimbo.

Ukuthintana Nesikhumba: KUGULA. Ukuthintana kungabangela ubuhlungu, ububomvu, ukusha, namabhamuza. Kungabangela izibazi ezihlala njalo. Ukuchayeka kanzima kungadala ukufa.

Ukuthintana Neso: KUBOLE. Ukuthintana kubangela ukusha okukhulu okubomvu, ukuvuvukala, ubuhlungu kanye nokungaboni kahle. Ukulimala okuhlala njalo okuhlanganisa nokungaboni kungavela.

Ukungenisa: Ingashisa izindebe, ulimi, umphimbo kanye nesisu. Izimpawu zingase zihlanganisa isicanucanu, ukuhlanza, amajaqamba esiswini kanye nesifo sohudo. Kungabangela umonakalo unomphela.

Imithelela Yokuchayeka Kwesikhathi Eside (Okungamahlalakhona): Ezimweni eziphansi: Kungabangela isikhumba esomile, esibomvu, esiqhekekile (dermatitis) kulandela ukuthintana kwesikhumba.

Ingakanani i-Phosphoric acid ku-coke?

I-Phosphoric acid kanye nosawoti bayo benza ama-25% ayo yonke i-asidi esetshenziswa ezimbonini zokudla. Ukusetshenziswa okuyinhloko kwe-phosphoric acid kusembonini yeziphuzo ezithambile, ikakhulukazi i-cola kanye neziphuzo zikabhiya wezimpande. I-Phosphoric acid isebenza njenge-acidulant futhi inikeza inothi elithile le-tart ukunambitheka kwale mikhiqizo.

Ukuhlushwa kwe-phosphoric acid ku-coke kuphansi kakhulu (cishe u-0.055%). Qhathanisa lokhu ne-asidi yewolintshi, ecishe ibe ngu-1%. Kufanele futhi kugcizelelwe ukuthi asikubambi ukudla noma isiphuzo emilonyeni yethu isikhathi eside, ngakho-ke lokhu kunciphisa imiphumela eyingozi yanoma yimaphi ama-asidi koqweqwe lwawo lwamazinyo.

I- Phosphoric acid isetshenziselwa ini?

Ukusetshenziswa kakhulu kwe-phosphoric acid kumanyolo, kudla cishe u-90% wokukhiqiza.

I-phosphoric acid yezinga lokudla (i-additive E338) isetshenziselwa ukwenza ukudla neziphuzo ezifana nama-colas ahlukahlukene kanye nojamu, kunikeze ukunambitheka okubabayo noma okumuncu. I-phosphoric acid nayo isebenza njengesivikelo. Iziphuzo ezithambile ezine-phosphoric acid, ezingafaka i-Coca-Cola, ngezinye izikhathi zibizwa ngokuthi ama-phosphate sodas noma ama-phosphates. I-Phosphoric acid eseziphuzweni ezithambile inamandla okubangela ukuguguleka kwamazinyo.I-Phosphoric acid nayo inamandla okufaka isandla ekwakhekeni kwamatshe ezinso, ikakhulukazi kulabo abake baba nezinso ngaphambilini.

Izicelo eziqondile ze-phosphoric acid zihlanganisa:

•  ekwelapheni okulwa nokugqwala nge-phosphate conversion coating noma passivation

•  ukuvimbela i-iron oxidation ngokusebenzisa inqubo yeParkerization

•  njengezinga elingaphandle le-phosphorus-31 nuclear magnetic resonance

•  kumaseli amafutha e-phosphoric acid

• ekukhiqizweni kwekhabhoni ecushiwe

•  ekucubunguleni i-semiconductor eyinhlanganisela, ukufaka i-Indium gallium arsenide ngokukhetha ngokuphathelene ne-indium phosphide

•  ekwenzeni i-microfabrication ukufaka i-silicon nitride ngokukhetha ngokuphathelene ne-silicon dioxide

• njengesilungisi se-pH kuzimonyo nemikhiqizo yokunakekelwa kwesikhumba

•  njenge-ejenti ye-sanitizing ezimbonini zobisi, zokudla, nezokuphisa

Izingozi Zezempilo Ezihambisana Ne-Phosphoric Acid

I-Phosphoric acid ingaba yingozi kakhulu lapho uthintana nesikhumba, uthintana namehlo, futhi ungeniswa. Kungase futhi kubangele ukucasuka uma umhwamuko uhogelwa. Leli khemikhali lingadala umonakalo esikhumbeni, emehlweni, emlonyeni, nasemgudwini wokuphefumula. Ngenxa yezingozi ezingase zibe khona ngenxa yaleli khemikhali, kubalulekile ukusebenzisa ukunakekela lapho uliphatha.

Ukuchayeka kaningi noma isikhathi eside kwinkungu ye-phosphoric acid kungaholela ekucasukeni kwamehlo okungapheli, ukucasuka okukhulu kwesikhumba, noma izinkinga zepheshana lokuphefumula elide. Ukuze uvikele impilo yakho lapho uphatha le khemikhali engase ibe yingozi, kubalulekile ukusebenzisa ukuqapha ngendlela yezimpahla zokuzivikela (i-PPE).

Iyini i-phosphoric acid esetshenziselwa ukudla?

Izinhlobo eziningi zamagciwane aziwayo zikhula nge-pH ekahle ephakathi kuka-6.5 no-7.0 esikalini se-pH.Ukwengeza ama-asidi angenabuthi eziphuzweni nasemikhiqizo yokudla kungehlisa i-pH iye ku-2.5, ngaleyo ndlela kunciphise amathuba okuba amagciwane akhule eziphuzweni nokudla okunoshukela.

I-Phosphoric acid iyisengezo esihle eziphuzweni ezithambile nokunye ukudla okugayiwe ngoba ayibizi futhi ayinabo ubuthi. Futhi yengeza ukunambitheka okumuncu okubabayo, okufana ne-citric acid esithelweni.

Iyini i-pH ye-phosphoric acid?

Njengamanye ama-acids, i-pH yesisombululo se-phosphoric acid ilingana ngokuqondile nokuhlushwa kwe-solute. Iyahlukahluka futhi kuye ngezinye izici ezifana nezinga lokushisa kanye nezinhlobo zama-ion ahlukanayo lapho into ene-asidi incibilika. Isibonelo, ku-0.1 N isixazululo samanzi, i-phosphoric acid ine-pH engu-1.5.

Kodwa-ke, lokhu kukutshela kuphela ukuhlangana kwama-ion e-hydronium esikalini se-logarithmic; ayibonisi uhlobo lwama-ion kanye nokuhlukana kwawo okuhlobene. Kubalulekile ukuqaphela ukuthi i-phosphoric acid iyi-triprotic acid, okusho ukuthi inamaphrothoni amathathu ane-acidic anamanani ahambisanayo e-pKa.

Ukuphatha kanjani ukushisa kwe-phosphoric acid?

I-phosphoric acid egxile kakhulu ingashisa isikhumba futhi ibangele ukulimala okubi kakhulu. Ngakho-ke kubalulekile ukuthatha zonke izinyathelo zokuphepha ezidingekayo lapho uphatha le khemikhali ezindaweni eziningi. Lokhu kusho ukusebenzisa izibuko namagilavu, kanye nephinifa laselabhorethri noma ingubo.

Uma isikhumba sakho sichayeke ku-phosphoric acid egxile kakhulu, hlambulula ngokushesha indawo ethintekile ngamanzi afudumele okungenani imizuzu engama-30 noma kuze kube yilapho kufakwa ukwelashwa okufanele.

Ingabe i-phosphoric acid ayilungile kuwe?

Ngokusho kwe-Joint The Food and Agriculture Organization yeZizwe Ezihlangene kanye ne-World Health Organization Expert Committee on Food Additives, 'kunobufakazi obuningi bokusekela ukuphepha kokwengezwa kwenani elincane le-phosphoric acid ekudleni. Ngakho-ke, ukusetshenziswa kwe-0.01-0.02%6 njenge-sequestrant, i-antioxidant noma 'synergist' ingxube yezempilo akufanele ibekhona.

I-Joint The Food and Agriculture Organization yeNhlangano Yezizwe Ezihlangene kanye Nomhlaba

IKomidi Lochwepheshe Lenhlangano Yezempilo Yezithasiselo Zokudla , 'ukusetshenziswa kwe

i-phosphoric acid ukunxephezela ukuntuleka kwe-asidi yesithelo, njengengxenye yokunambitheka nangezinye izindlela, empeleni phakathi 'kwendikimba' yamaphosphates atholakala ngokwemvelo ekudleni, akufanele kube nenkinga'.
