Iiminerali ze-spinel zinempembelelo ebalulekileyo kwiimpawu zokushisa eziphezulu zezinto eziphikisayo. Ngokomzekelo, ngenxa ye-coefficient encinci yokwandisa i-thermal ye-spinel (α=8.9x10-*/℃ kwi-100 ~ 900℃), i-spinel isetyenziswe njenge-agent ebophelelayo (Okanye ebizwa ngokuba yi-cementing phase, matrix), izitena ze-magnesia-alumina ezine-periclase. njengenqanaba lekristale eliphambili, xa ubushushu buguquka ngokukhawuleza, uxinzelelo lwangaphakathi olwenziwe luncinci, kwaye izitena azilula ukuphuka, ngoko ke ukuzinza kwe-thermal yezitena kunokuphuculwa (izitena ze-magnesia-alumina Ukuzinza kwe-thermal yi-50 ~ 150 amaxesha).

Ukongeza, ngenxa yokuba i-spinel ineempawu ezilungileyo ezinjengokuqina okuphezulu, iipropathi ezizinzile zeekhemikhali, kunye nenqanaba eliphezulu lokunyibilika, kwaye lixhathise kakhulu ukubola ngokunyibilika ngeendlela ezahlukeneyo kumaqondo aphezulu obushushu, ubukho beeminerali ze-spinel kwiimveliso buye baphucula ukusebenza kobushushu obuphezulu. imveliso.

Esona sizathu sibalulekileyo sokuba iqondo lobushushu obuphezulu bobushushu obuthambileyo bezitena ze-magnesia-alumina (indawo yokuqala ayikho ngaphantsi kwe-1550-1580℃) iphezulu kunezitena ze-magnesia (indawo yokuqala ingaphantsi kwe-1550 ℃) kukuba ukubunjwa kwe-matrix kwahlukile. .

Ukushwankathela, i-spinels zizinto ezigqwesileyo ngokubhekiselele kwi-melting point, ukwanda kwe-thermal, ubunzima, njl., kunye neepropati zeekhemikhali ezizinzileyo, ukuchasana okunamandla kwi-alkaline slag, kunye nokuchasana nokukhukuliseka kwesinyithi esinyibilikisiweyo. .

Ulwazi olusisiseko

I-Junsheng high-purity magnesia-aluminium spinel inomxholo ophantsi kakhulu wokungcola kunye nokusebenza okuphezulu kobushushu obuphezulu. I-spinel ye-High-purity spinel ifanelekile kwiindawo ezenziwe ngaphambili ezifana nezitena eziphefumulayo, izitena zokuhlala, i-ladles, i-firnace top covers, izinto eziphikisayo ze-rotary kilns, kunye nezinto eziphikisayo zokunyibilikisa i-alloys. iimveliso, kunye ne-spinel-containing shape sets.

Iimveliso zinokunceda ukuphucula i-slag corrosion resistance ye-refractory materials, kunye nokusombulula ingxaki yokuqhekeka kwezinto ezibangelwa ukongeza izinto eziluhlaza ze-magnesium.
