Iiceramics zeAlumina: izinto ezinganyangekiyo ezinazo iimpawu zekhemikhali ezizinzileyo

Kwicandelo lesayensi yezinto eziphathekayo, sisoloko sikhangela izinto ezintsha ezineempawu ezintle kunye nozinzo. Phakathi kwazo, ii-alumina ceramics zisetyenziswa kakhulu kwiindawo ezahlukeneyo ngenxa yeempawu zazo ezintle zomzimba nezekhemikhali, kunye nokumelana nobushushu obuphezulu kunye nokumelana nokugqwala. Namhlanje, makhe sijonge ngokusondeleyo uzinzo lweekhemikhali ze-alumina ceramics.

Okokuqala, uzinzo lweekhemikhaliiiseramikhi ze-aluminaIbonakala kakhulu ekuchaseni kwayo uninzi lwee-asidi, iziseko kunye nee-oxidants. Oku kungenxa yokuba ulwakhiwo lwe-alumina ceramics luqinile kwaye unxibelelwano phakathi kwee-molecules luqinile, nto leyo eyenza ukuba ikwazi ukugcina imo yayo yokuqala kunye neempawu zayo kwiindawo ezinzima kakhulu. Olu zinzo lwenza i-alumina ceramics isetyenziswe kakhulu kwiikhemikhali, ipetroliyam, isinyithi kunye neminye imimandla.

Okwesibini, ukuzinza kweekhemikhali ze-alumina ceramics kubonakala nakwiimpawu zayo ze-antioxidant. Phantsi kweemeko zobushushu obuphezulu, izinto ezininzi ziya kusabela kwi-oksijini, nto leyo ebangela ukuba ulwakhiwo kunye neempawu zazo zitshintshe. Nangona kunjalo, ii-alumina ceramics zihlala zizinzile kule ndawo kwaye azisabela kwi-oksijini. Oku kuxhathisa i-oxidation kwenza ii-alumina ceramics zidlale indima ebalulekileyo kwi-aerospace, emkhosini nakwezinye iindawo.

Ukongeza, ukuzinza kweekhemikhali ze-alumina ceramics kubonakala nakwi-asidi kunye ne-alkali corrosion resistance. Kubomi bethu bemihla ngemihla, ii-asidi kunye neziseko zizinto eziqhelekileyo, kwaye zinefuthe lokubola kwizinto ezininzi. Nangona kunjalo, ii-alumina ceramics ziyakwazi ukumelana nokubola kwe-asidi kunye ne-alkali kwaye zigcine iipropati zazo zokuqala kunye nolwakhiwo. Oku kuxhathisa ukubola kwe-asidi kunye ne-alkali kwenza ii-alumina ceramics zisetyenziswe kakhulu ekulungisweni kokutya, kwikhemistri, kwezonyango nakwezinye iindawo.

Ngokubanzi, iipropati zeekhemikhali ze-alumina ceramics zizinzile, ukuze zikwazi ukugcina ukusebenza kakuhle kunye nokuma kakuhle kwiindawo ezahlukeneyo ezinzima. Olu zinzo lwenza i-alumina ceramics isetyenziswe kakhulu kwiindawo ezininzi.
