Ngokuukudaya iiasidiube nokusebenza kakuhle kwibala leendwangu zoshishino, kwaye amasimi amaninzi aqalise ukusebenzisa i-acids yokudaya endaweni ye-acetic acid. Nangona kunjalo, i-asidi yokudaya nayo ineemfuno ze-PH, kwaye ububanzi besicelo awufani!
I-asidi yokudaya isetyenziswa ikakhulu kwimpahla ezilukiweyo ezifana noboya, isilika kunye nenayiloni, kwaye zinokudlala indima ebalulekileyo kwimveliso yesikhumba, iphepha kunye ne-inki. Ngoko ufumanisa njani ukuba uhambelana njani ezahlukeneyoukudaya iiasidikwizicelo ezahlukeneyo?
Zeziphi iindidi zeeasidi zokudaya ezisetyenziswayo?
1. Idayi ze-asidi ezinamandla
Le idayi yeyona isisiseko, kunye nedayi yokuqala ene-asidi, ehambelana ngakumbi kwaye kulula ukuyibala xa idayi kunye nokuluka iimveliso zoboya, kuba ulwakhiwo lwemolekyuli yolu hlobo lwe-asidi yokudaya lulula kakhulu, kwaye luyenza ivakale. ihlwempu kakhulu.
2. Idayi eneasidi ebuthathaka
Xa kuthelekiswa ne-acidic edayiyo kakhulu ye-acidic acid, ubunzima bayo bemolekyuli bunzima ngakumbi nangakumbi, ukuze ukuhambelana koboya kukhulu. Xa usebenzisa idayi ye-asidi ebuthathaka ukudaya kunye nokuluka uboya, inokukhusela iimolekyuli zoboya ukuya kwinqanaba elikhulu, iphucule ukuqina kwayo, kwaye umbala uya kubonakala ungcono, kodwa ukudaya akufani kangako.
3. Ukudaya iasidi
Fumana abavelisi abathile ukuba babonelele nge-asidi yokudaya njenge-mordant yokudaya kunye nokuluka, unokwenza umaleko we-metal complex kwilaphu. Nangona inkqubo yokudaya iya kuba nzima ngakumbi, ukusetyenziswa kwale asidi yokudaya kunokwenza ilaphu likwazi ukumelana nokukhanya kwelanga, ukuhlamba okuqinileyo kunye nokukhuhlana kwangaphandle.
Ke kutheni abavelisi abaninzi beqala ukukhetha iiasidi zokudaya?
Abantu abaninzi bacinga ukuba ekubeni i-asidi, ngokuqinisekileyo iya kubangela umonakalo kwi-fiber element, kwaye ngeli xesha, i-asidi yokudaya ayinakho ubukho be-asidi ye-inorganic, ukuze i-cellulose ingabi buthathaka xa idibana ne-hydrolysis, ngaloo ndlela yonakele, ngokuqinisekileyo, kukhuselekile ukusebenzisa!
Iasidi yokudaya nayo inesithinteli esilungileyo ngokuchasene neasidi kunye nesiseko xa isetyenziswa. Emva kokusetyenziswa kwe-asidi yokudaya, ixabiso le-PH ye-buffer linokulungiswa kwinkqubo yokugcina uzinzo lwesiphumo sokudaya.
Emva kokusetyenziswa kwe-asidi yokudaya, kunokuphucula umphumo wokudaya kwelaphu ukuya kwinqanaba elithile, kunye nezinto ezifana ne-acetic acid, izinzile ngakumbi kwiqondo lokushisa xa kwakhiwa, kwaye umphumo ungcono xa usetyenziswa.
Ngokubanzi, ukusetyenziswa kwe-acids yokudaya kusebanzi kakhulu kwaye kubalulekile! Ukuba ufuna ukuqalisa, kucetyiswa ukuba ufumane umenzi oqeqeshiweyo nothembekileyo ngokuthe ngqo
