Izici ze-White Fused Alumina ze-Refractory Coatings
I-alumina emhlophe ehlanganisiwe Kwezembozo ezimelana nokushisa, zinezinga eliphezulu lokuncibilika, ukuqina okuhle kokushisa, ukumelana nokugqwala kwamakhemikhali okuqinile, ubulukhuni obuphezulu kanye nokumelana nokuguguleka, ukusebenza kahle, kanye nezembozo ezifanayo neziqinile. Izici ezibalulekile zichazwe ngezansi:
I. Indawo Ephakeme Yokuncibilika Nokuzinza Kokushisa
I-alumina emhlophe ehlanganisiwe inezinga eliphezulu lokuncibilika, igcina izakhiwo zomzimba nezamakhemikhali ezizinzile ngaphansi kwamazinga okushisa aphezulu ngaphandle kokuncibilika noma ukuguquka. Lokhu kuyenza ibe yinto efanelekile yokuthuthukisa ukusebenza okungenakuphikiswa kwezimbozo, ukuqinisekisa ukuthi zimelana nokuchayeka isikhathi eside emazingeni okushisa aphezulu ezithandweni, ezithandweni zokuncibilikisa, kanye nemishini efanayo ngaphandle kokwehluleka.
II. Ukumelana Nokugqwala Kwamakhemikhali
I-alumina emhlophe ehlanganisiwe ikhombisa ukumelana okuphezulu nezinto ezibolayo ezifana nama-asidi nama-alkali, ingathinteki ngamakhemikhali amaningi. Ezindaweni ezibolayo ngaphakathi kwezimboni ezifana nokucubungula amakhemikhali kanye ne-metallurgy,izembozo eziphikisayoequkethe i-alumina emhlophe ehlanganisiwe igcina ukuzinza kwesikhathi eside, yandisa ngempumelelo isikhathi sokuphila kwemishini.
III. Ukuqina Okuphezulu Nokumelana Nokugqokwa
Njengoba i-Mohs ilukhuni kakhulu kune-diamond ne-silicon carbide, i-alumina emhlophe ehlanganisiwe ikhombisa ukumelana nokuguguleka okumangalisayo. Imelana nokushaqeka nokuguguleka okuvela kuketshezi olunesivinini esikhulu kanye nezinhlayiya ngenkathi igcina ubuso bubushelelezi futhi buthambile ngokuhamba kwesikhathi.
IV. Ukusebenza Okuhle Kakhulu Kohlelo Lokusebenza
I-alumina emhlophe ehlanganisiweingasetshenziswa ngokufafaza, ukuxubha, noma izindlela ezifanayo. Ngesikhathi sokufaka, isabalalisa ngokulinganayo futhi ibopha ngokuqinile ne-substrate ukuze yakhe ungqimba oluqinile oluphikisayo. Ukuhlanzeka kwayo okuphezulu kanye nokuqukethwe kwayo okuphansi kokungcola kunciphisa ubunzima bokufaka, kuthuthukisa ukusebenza kahle, kuqinisekisa ukufana kokumboza kanye nobuningi, futhi kunciphise izingozi zokuqhekeka noma zokuxebuka.
V. Ukugqoka Okufanayo Nokujiyile
Izembozo ezikhipha umoya eziqukethe i-alumina emhlophe ehlanganisiwe zakha izendlalelo eziqinile ngokulinganayo ngesikhathi sokusetshenziswa, zinciphisa ngempumelelo ukugoba ngenkathi zandisa ubuningi namandla. Lokhu kunegalelo ekuthuthukisweni kokusebenza kwezembozo, okuhlanganisa ukugoba, ukumelana nokushayisana, kanye nokumelana nokuhuzuka.
VI. Ukumelana ne-Oxidation kanye nokumelana ne-Thermal Shock
I-alumina emhlophe ehlanganisiwe ibonisa ukumelana okunamandla kwe-oxidation kanye nokuwohloka okuncane kwamakhemikhali ngesikhathi sokusetshenziswa isikhathi eside, okunciphisa kakhulu ukuqhekeka kwe-coating kanye nokuguga ezindaweni ezikhipha i-oxidation. Ngaphezu kwalokho, ithuthukisa ukumelana nokushaqeka kokushisa kanye nokumelana nokuguguleka kwe-slag ngokusebenzisa ama-composite formulations anama-oxide ahlukahlukene noma ama-non-oxide.
VII. Ukusebenza Okuhlukahlukene Nokusebenza Okubanzi
Izembozo ezikhipha umoya eziqukethe i-alumina emhlophe ehlanganisiwe azifanele nje kuphela ukuvikela imishini yezimboni eshisa kakhulu kodwa futhi zingalungiswa ukuze zihlangabezane nezidingo ezahlukahlukene ngokulungisa usayizi wezinhlayiya.
