Dintshayelelo enento yokwenza
Kwinkqubo yokunyibilikisa kunye nokugcinwa kobushushu be-aluminium kunye ne-aluminium alloys, ulawulo lobushushu be-aluminium etyhidiweyo kunye ne-aluminium etyhidiweyo yinto ephambili yokuqinisekisa umgangatho weemveliso ze-aluminium.Inokunqanda i-oxidation ebangelwa kukutshiswa ngokugqithisileyo kwe-aluminiyam etyhidiweyo kunye ne-aluminiyam etyhidiweyo, ngaloo ndlela igcina ukusetyenziswa kwamandla.Kuba ci-asting ye-aluminiyam etyhidiweyo kunye ne-aluminiyam etyhidiweyo,tubushushu bakhe budla ngokuba malunga nama-720°C.Ukuqinisekisa ukuba ulwelo aluminiyam kunye namanzi aluminiyam agcinwa kobu bushushu, ulwelo aluminiyam aluminiyam amanzi.thermocoupleidlala indima ephambili njengenzwa yobushushu efakwe ngokuthe ngqo kulwelo lwe-aluminiyam kunye namanzi e-aluminiyam ukulinganisa ubushushu.
Okokuqala, ukuqonda i-aluminiyam elulwelo, i-aluminiyam yentsimbi engamanzi isebenza kakhulu, ukunyanzeliswa kwee-athom ze-aluminiyam kunamandla, kwaye yonakalisa kakhulu isinyithi.I-interlayer yefilimu ye-oxide iqulethe inani elikhulu le-athomu ye-hydrogen, enokuthi ibambelele ngokulula kumphezulu wesinyithi esomeleleyo kwaye idle isinyithi esiqinileyo.
Ngokusekelwe kwezi zizathu zingasentla, kubaluleke kakhulu ukuba ulwelo lwe-aluminium kunye ne-aluminium yokulinganisa ubushushu bamanzi i-thermocouple ukusebenzisa i-material enganyangekiyo kwi-corrosion ye-aluminium engamanzi kunye namanzi e-aluminium njengetyhubhu yokukhusela i-thermocouple.I-iron-based alloy thermocouple protection tube okanye i-Si3N4 edibeneyo ye-SiC yokukhusela i-thermocouple tube,uii-thermocouples ezisebenza ngokuphezulu njengezinto zokuva ubushushu.Inamandla amakhulu, ukuxhathisa okuqinileyo kwe-corrosion, ixesha elifutshane lokuphendula i-thermal, ubomi benkonzo ende kunye nomlinganiselo wokushisa oqhubekayo kwiiyure ezingama-24.
Ikakhulu ilungele ukulinganisa ubushushu kwi-aluminium processing kunye ne-aluminium electrolysis industrie.
[Indlela yokulungisa]: Inokulungiswa ngeflange esisigxina (ubungakanani beflange ngokwezifiso)
I-tube yokukhusela yenziwe ngetsimbi engapheliyo ngokungagqibekanga.Ukulinganisa ixesha elide ngaphezu kwe-800 degrees, kucetyiswa ukuba ityhubhu yokukhusela inokwenziwa ngokwezifiso kunye ne-2520 impahla, i-GH3030 kunye ne-GH3039 impahla, kunye ne-anti-corrosion ingenziwa ngokwezifiso nge-316L impahla.Kucetyiswa ukuba usebenzise i-2.0mm okanye i-2.5mm kwi-diameter yecingo elingaphezulu kwe-800℃.Ityhubhu yokukhusela i-single-layer ingasetyenziselwa ukulinganisa ubushushu besithando somlilo, kwaye ukongezwa kwe-silicon carbide ingasetyenziselwa ukulinganisa ubushushu besisombululo setsimbi.
Ityhubhu yangaphakathi yenziwe ngentsimbi engenasici, kwaye ityhubhu yangaphandle inokuxhotyiswa ityhubhu yokukhusela i-silicon carbide, ephinda yenziwe ngesilicon carbide.Umphandle wecasing ene-double-layer casing-resistant kunye ne-corrosion-resistant.Isetyenziswa ikakhulu kwi-metallurgy, kushishino lweekhemikhali, kunye nokunyibilikiswa kwentsimbi okungeyontsimbi.Kufanelekile ngokukodwa ukulinganisa ubushushu be-aluminium etyhidiweyo kunye nobhedu.Ngenxa yobuninzi bayo obuphezulu, ayiyi kuchithwa yi-aluminium etyhidiweyo ngexesha lokulinganisa ubushushu;inokumelana nokothuka kwe-thermal, ukugquma kunye nokumelana ne-oxidation, ukumelana nokunxiba kunye nokumelana nobushushu obuphezulu, kunye nobomi benkonzo ende.
