Ukusetshenziswa kwe-formic acid esikhumbeni

Isicelo sei-formic acid esikhumbeni

Isikhumba isikhumba sesilwane esine-denatured esitholakala ngokucutshungulwa ngokomzimba namakhemikhali njengokususwa kwezinwele nokushukwa.I-Formic acid isetshenziswe ezixhumanisini ezihlukahlukene njengokususwa kwezinwele, ukushuka, ukulungisa umbala nokulungiswa kwe-pH ekucutshungulweni kwesikhumba. Indima ethile ye-formic acid esikhumbeni imi kanje:

1. Ukususwa kwezinwele

I-Formic acid ingathambisa uboya, futhi ikhuthaze ukuwohloka nokususwa kwamaprotheni, esiza ekuhlanzeni nasekucutshungulweni okulandelayo kwesikhumba.

2. Ukushukwa

Enqubweni yokushukwa kwesikhumba,i-formic acid ingasetshenziswa njenge-agent engathathi hlangothi ukusiza i-ejenti yokushuka esikhumbeni ukuba idlale ngokugcwele indima yayo, ngaleyo ndlela ithuthukise ukuqina nokuthambile kwesikhumba.

3. Ukusetha nokudaya

Ngesikhathi sokuhlelwa kombala kanye nenqubo yokudaya isikhumba,i-formic acid isiza udayi ukuba ungene esikhumbeni futhi uthuthukise umphumela wokudaya, kuyilapho uvikela isikhumba emonakalweni obangelwa ama-molecule odayi. Ukusetshenziswa okunengqondo kwei-formic acid ingathuthukisa ukuthungwa kwesikhumba futhi yenze ubuso besikhumba bushelelezi futhi bukhanye.

4. Lungisa i-pH

I-Formic acid ingasetshenziselwa ukulawula i-pH ngesikhathi sokucubungula isikhumba, okunciphisa usayizi we-pore futhi kwandise ukuminyana kwesikhumba, ngaleyo ndlela kuthuthukise ukumelana kwamanzi nokuqina. Ngokuvamile, inani le-pH lesikhumba esingenalutho ngemuva kokuthambisa kwe-desliming ngu-7.5 ~ 8.5, ukuze wenze isikhumba esimpunga silungele izimo zokusebenza zenqubo yokuthambisa, kuyadingeka ukulungisa inani le-pH lesikhumba esingenalutho, linciphise libe ngu-2.5 ~ 3.5, ukuze ilungele ukushukwa kwe-chrome. Indlela eyinhloko yokulungisa inani le-pH i-acid leaching, esetshenziswa kakhului-formic acid. I-Formic acid inama-molecule amancane, ingena ngokushesha, futhi inomphumela wokufihla oketshezini lokushuka kwe-chrome, ukuze ukuhlangana kokusanhlamvu okuncane kwesikhumba kube kuhle ngesikhathi sokushukwa. Ivame ukusetshenziswa ngokuhambisana ne-sulfuric acid ngesikhathi sokuvuthwa kwe-asidi.
