Wali band acid, lapho ifomula H 3 PO 4, obizwa nangokuthi wali band. Egcekeni ngaphansi kwezimo ezivamile iyisimo esiqinile wokuhlanganisa. zinhlayiya ezincane we ketshezi Ayinambala. Acid okubonakala kalula oncibilikayo emanzini, Ethanol nezinye ezihogelwayo. In the state okuqinile kanye ketshezi, amangqamuzana efana nesimo zizihlanganisa ngu-hydrogen izibopho nezinhlupheko, ngenxa yalesi sizathu yagxila H3PO4 ine viscosity anda. Ukubila iphuzu 42,3 C, kanti ngokubeka amalahle kuze kufinyelele 213 C iba pyrophosphoric acid H 4 P 2 O 7.
Wali band acid kuyinto amandla electrolyte nalasemkhatsini kanye tribasic acid, ke dissociates stepwise ngezinyathelo ezintathu e izixazululo aqueous.
Inkhulumo lelungiselelwe orthophosphoric acid ngokuvamile usawoti yalo eziqukethwe namaminerali phosphate - apatite ne phosphorus, ngaphansi kwethonya sulfuric acid. Futhi, ngokuphuza hydration phosphorus oxide (V) by hydrolysis noma i egcekeni wezinto ezingaphili - phosphor pentachloride.
Wali band acid is wasithukuthelela lezisekelo, metal oxides, nosawoti, izinsimbi asebenzayo futhi acid eqinile. Lapho uxhumana hydroxides neutralization ukuphendula kwenzeka, umphumela okuyinto kumiswa usawoti namanzi. Benziwa zensimbi oxides lwakha usawoti namanzi. Lapho zisabela ukusabela nosawoti exchange senzeka, okuyinto etholakala uma usawoti entsha kanye acid. Basabela kanjani orthophosphoric acid ne esiliva nitrate (usawoti) kuyindlela yemvelo yokusabela lapho qualitative, siwuvumele ukuthola izixazululo zayo. Inani eliphansi - ophuzi kwenze - phosphate Isiliva (Ag 3 PO 4). Njengoba izinsimbi asebenzayo, okuyizinto phakathi Beketova kuze hydrogen engena esikhundleni ukusabela. Ukuhlanganyela acid eqinile (bleach) liveza ubunjalo ezimbili (amphoteric) futhi esakha nosawoti eziyinkimbinkimbi - phosphoryl. Futhi, lesi sithako kungenziwa thermally ukubola ukuba diphosphoric acid.
Wali band acid, ukusetshenziswa okuyinto kabanzi, asetshenziswa kabanzi ezimbonini eziningi. Ngokwesibonelo, kwezolimo, ikakhulukazi ngenxa ukukhiqizwa umquba aqukethe phosphorus. umquba okunjalo kungaba ngcono ukukhiqiza hhayi kuphela, kodwa futhi kahle kuthinte Ukwakheka microbiological enhlabathini, okwaba nomthelela ekwakhekeni kanye ekwandeni nama-bacterium awusizo, kanye ukwandisa hardiness izitshalo. Esikhathini umkhakha ukudla acid lisetshenziswa njengedivaysi ukudla okufakiwe E 338, okuyinto kuqukethwe esincane kule marmalade, isiraphu kanye iziphuzo carbonated. Kungenxa yokuthi okuqukethwe wali band acid kanye citric acid e iziphuzo lapho ukusetshenziswa ngokweqile kwenzeka ukubhujiswa izinyo. Le mpahla ukuthambisa izinyo koqweqwe lwawo futhi dentin ibilokhu isetshenziswa odokotela bamazinyo. Ngokwesibonelo, wali band acid oqukethe nokunamathisela ekhethekile lisetshenziswa izinyo ngaphambi ukugcwaliswa ke futhi ubangela izicubu demineralization. Ingqikithi isetshenziselwa ukwelashwa imbewu nokumiswa non-ezivuthayo ukhuni upende varnishes nezinto zokwakha (non-oluvuthayo phosphate Foam fosfodrevesnye ipuleti). Ngezenzo elisetshenziswa brazing ithusi, izinsimbi ayoni, insimbi engagqwali wokuhlanza okususa ebusweni oluhlukile lwensimbi oxides. Futhi esetshenziswa descaling, yokuwasha ezinto eziphilayo nasemkhakheni wezinto.
Wali band acid kutholakala wokusetshenziswa okusebenzayo kanye lomnotho ngenxa izakhiwo zabo physicochemical futhi iphansana izindleko ukulungiselela.
