Isikulufu Se-Titanium Esenziwe Ngokwezifiso Sokusetshenziswa Kwezimboni

Ukukhiqizwa kwezikulufu ze-titanium

Njengamanje, ukukhiqizwa kwasekhaya nezangaphandle kwe-titanium kanye ne-titanium alloy wire ikakhulukazi kusetshenziswa ukudweba, ukugaya, ukuxubha, ukugeza kwe-asidi ne-alkali, ukusika, ukuqondisa kanye nezinye izinqubo, kuyo yonke inqubo yokukhiqiza kudinga ukudlula ukudweba okungu-20, ukugaya okuphakathi kokuthathu kuya kwezine, i-annealing eyishumi emaphakathi, inqubo yokugeza i-asidi emibili kuya kwemithathu ne-alkali, inqubo yokuqondisa. Izikulufu ze-Titanium, esimweni sokushisa okuphezulu kokushisa ngokusebenzisa isikhunta sembobo ukulawula ububanzi bocingo, ukucubungula ucingo oluqondile kunzima, ukunemba okungalungile kwendawo, ukumuncwa kwe-hydrogen ne-oxygen okungathi sína, isisindo se-disc eyodwa siphansi, asikwazi ukuhlangabezana nezidingo ukunemba okuphezulu kwe-titanium; I-Acid ne-alkali yokuhlanza indawo inokungcola okukhulu, izikulufu ze-titanium, zingacosha kuphela i-titanium, futhi azikwazi ukukhiqiza i-titanium ekhanyayo. Inqubo yokuqondisa izokwenza ubuso bezinto ze-titanium bube okusanhlamvu okuqondisayo okunzima ukukuqeda, ukuze umonakalo ongaphezulu we-titanium ube mkhulu kakhulu.

Izikulufu ze-Titanium zinokumelana nokugqwala okuhle kakhulu

  I-passivity ye-titanium incike ebukhoneni befilimu ye-oxide, ukumelana kwayo nokugqwala endaweni ye-oxidizing kungcono kakhulu kune-rencing medium, futhi izinga eliphezulu lokugqwala lingenzeka endaweni yokunciphisa. I-Titanium ayigqwali kweminye imithombo yezindaba ebolayo, njengamanzi olwandle, i-chlorine emanzi, izixazululo ze-chlorite ne-hypochlorite, i-nitric acid, i-chromic acid, i-metal chlorides, ama-sulfide nama-organic acid. Nokho, phakathi nendawo esabela nge-titanium ukuze ikhiqize i-hydrogen titanium ngokuvamile inezinga eliphezulu lokugqwala. Kodwa-ke, uma inani elincane le-oxidizing agent lengezwa ku-asidi, i-titanium izokwakha ifilimu ye-passivation. Ngakho-ke, ekuxubeni kwe-sulfuric acid - i-nitric acid noma i-hydrochloric acid - i-nitric acid, futhi ngisho ne-hydrochloric acid equkethe i-chlorine yamahhala, i-titanium iyamelana nokugqwala. Ifilimu ye-Titanium protective oxide ivame ukwakheka lapho insimbi ishaya amanzi, ngisho namanani amancane noma lapho kukhona umhwamuko wamanzi. Uma i-titanium ivezwa endaweni eqinile ene-oxidizing lapho amanzi engekho ngokuphelele, i-oxidation esheshayo ingenzeka futhi ikhiqize ukusabela okuvuthayo okunodlame, okuvamise ukuzenzakalelayo. Ukuziphatha okunjalo kwenzeka lapho i-titanium iphendula ne-nitric acid evuthayo equkethe i-nitrogen oxide eyeqile nalapho i-titanium iphendula nge-chlorine eyomile. Nokho, ukuze kuvinjelwe ukwenzeka kokusabela okunjalo, inani elithile lamanzi kufanele libe khona.
