Iithegi zeMveliso

Kwiinkqubo zobushushu obuphezulu apho ulawulo lwamanzi, ukunganyangeki kokukhukuliseka, kunye nokuzinza kwe-thermal kubaluleke kakhulu,isilicon carbide (SiC) imilomogqama njengommangaliso wobunjineli. Ngokungafaniyo ne-ceramic yegeneric okanye imilomo yentsimbi, iipropathi ezizodwa ze-SiC zijongana nemingeni ekutshiseni, ekuqhubeni, nakwiinkqubo zokutshiza kwimizi-mveliso. Eli nqaku liphonononga ukuba kutheni amashishini esamkela ngakumbi imilomo ye-SiC ukuguqula ukusebenza kwezona zicelo zifunwa kakhulu.

1. Yenzelwe iNdawo zoLwando olugqithisileyo

Imilomo ye-SiC iyagqwesa ekulawuleni isantya esiphezulu, ulwelo olunobushushu obuphezulu kunye neegesi:

(1) Ukuchasana nokukhukuliseka: Ukumelana namasuntswana abrasive kwii-injection ze-slurry slurry, iinkqubo ze-sandblasting, okanye i-rocket propellants ngaphandle kwe-deformation-induced deformation.

(2) Ukusinda kwiThermal Shock: Umjikelo okhawulezayo phakathi kwamaqondo obushushu agqithisileyo (umzekelo, inaliti yamafutha kwiziko lesinyithi) ngaphandle kokuqhekeka, ngenxa yokwandiswa kwe-thermal ephantsi ye-SiC.

(3) Ukungangeni kweChemical: Ukuxhathisa ukubola kwi-acidic / alkaline sprays, iityuwa ezityhidiweyo, okanye amadangatye oxidizing, uqinisekisa ijometri ye-orifice engaguqukiyo.

2. Ulawulo lokuHamba oluchanekileyo kwiiNkqubo eziBalulekileyo

Kwizicelo ezifuna ukuchaneka kwenqanaba le-micron, imilomo ye-SiC ihambisa ukuthembeka okungenakuthelekiswa nanto:

(1) Ijiyometri yeOrifice eZinzileyo: Gcina amanqanaba okuqukuqela achanekileyo kunye neepateni zokutshiza nasemva kokuvezwa ixesha elide kwi-1500 ° C + imekobume, ngokungafaniyo neentsimbi ezijikayo okanye iiseramics ezithomalalisa.

(2) UkuNcitshiswa kokuvala: Ukugqitywa komphezulu ogudileyo kunciphisa ukwakhiwa kwezinto kwii-injector zamafutha okanye iinkqubo zokutshiza iikhemikhali.

(3) Ukunyamezela koxinzelelo oluphezulu: Ukumelana noxinzelelo lwe-hydraulic oludlula i-500 MPa, ilungele ukusika i-waterjet okanye i-aerospace propulsion.

3. Ukunika amandla ukutsha okuFanelekileyo

Imilomo yeSiC ibalulekile ekwandiseni iinkqubo zokutsha ezisebenza ngamandla:

(1) Ukuzinza komlilo: Uyilo olumelana nobushushu luqinisekisa ukuxutywa kwe-fuel-air efanayo kwiiinjini zegesi okanye izitshisi zemizi-mveliso, ukunciphisa iindawo ezitshisayo kunye nokukhutshwa kwe-NOx.

(2) Ukuguquguquka kweFuel: Iyahambelana ne-hydrogen, i-biofuels, okanye i-oyile enzima, exhasa ukutshintshela kwimithombo yamandla ezinzileyo.

(3) Ukusebenza kakuhle kwe-Thermal: Ukunciphisa ilahleko yobushushu ngeendonga ngenxa ye-SiC ephezulu ye-thermal conductivity, ukuphucula ukusebenza kwegumbi lokutsha ukuya kuthi ga kwi-15%.

Ngaphambili: I-silicon carbide iilayini ze-ceramic

Okulandelayo: Iityhubhu ezikhazimlayo ze-silicon carbide

I-Shandong Zhongpeng Special Ceramics Co., Ltd yenye yezona zisombululo zikhulu ze-silicon carbide zeceramic ze-ceramic e-China. I-ceramic yobugcisa be-SiC: Ubunzima be-Moh yi-9 (ubunzima be-Moh entsha yi-13), kunye nokumelana okugqwesileyo kukhukuliseko kunye ne-corrosion, i-abrasion egqwesileyo - ukuxhathisa kunye ne-anti-oxidation. Ubomi benkonzo yemveliso ye-SiC yi-4 ukuya kwamaxesha ama-5 ubude ngaphezu kwe-92% yezinto ze-alumina. I-MOR ye-RBSiC yi-5 kumaxesha e-7 ye-SNBSC, ingasetyenziselwa imilo enzima ngakumbi. Inkqubo yekoteyishini ikhawuleza, ukuhanjiswa kuthenjisiwe kwaye umgangatho ungowesibini. Sihlala sizingisa ukucela umngeni kwiinjongo zethu kwaye sibuyisele iintliziyo zethu kuluntu.
