Mullite Sand
Product Information
Mullite sandis a aluminium silicate refractory material, inowanzo shandiswa musimbi isina tsvina chaiyo yekukanda maitiro. Iyo refractoriness ndeye 1750 madhigirii. Iyo yakakwirira iyo aruminiyamu yemukati mumullite jecha, iyo inodzika iyo iron yemukati, uye idiki guruva, zviri nani kunaka kwemullite jecha chigadzirwa. Mullite jecha rinogadzirwa nepamusoro-tembiricha sintering yekaolin.
Features:
1. Nzvimbo yepamusoro yekunyungudika, kazhinji iri pakati pe1750 ne1860°C.
2. Kugadzikana kwakanaka kwepamusoro-tembiricha.
3. Low thermal kuwedzera coefficient.
4. Kugadzikana kwemakemikari yakakwirira.
5. Inonzwisisika particle size distribution inobvumira kusarudzwa uye kugadziriswa kunobva pane zvakasiyana-siyana zvekukanda maitiro uye kukanda zvinodiwa.

Applications
Mwongo wekukandira nemazvo kugadzirwa kwegoko remukombo (maitiro ekunamira patani yewakisi nemateru akawanda ezvezvinhu zvinoramba kunyunguduka kugadzira goko rekunze. Kana patani yewakisi yanyunguduka, panoumbwa gomba rekudira simbi yakanyungudutswa). Mullite jecha rinonyanya kushandiswa serefractory aggregate mugoko re mold uye rinoiswa kune akasiyana akaturikidzana egoko, kunyanya sezvinotevera:
1. Surface Shell (Inotsanangura zvakananga iyo Yepamusoro Hunhu hwekukanda)
Basa:Iyo yekumusoro layer inosangana yakanangana nekukandira uye inofanirwa kuve nechokwadi chekupera kwepamusoro (kunzvenga hukasha uye gomba) ukuwo uchishingirira kubata kwekutanga kwesimbi yakanyungudutswa.
2. Back Shell (Inopa Yakazara Simba uye Breathability)
Basa:The back shell is a multi-layered structure kunze kwepamusoro pedenga. Inotsigira kusimba kwese kwegomba rekuumbwa (kudzivirira deformation kana kudonha panguva yekudururwa) uku uchivimbisa kufema (kuburitsa magasi kubva mugomba uye kudzivirira porosity mukukanda).
3. Specialized Applications for High-Demand Castings
High-temperature alloy castings:akadai sema blades einjini ye turbine (kudurura tembiricha ye1500-1600 ° C), inoda kuti goko rekuumbwa rimire kutonhora kwakanyanya. Mullite jecha rakakwirira refractoriness rinogona kutsiva iro rinodhura zircon jecha (inonyunguduka 2550 ° C, asi inodhura), kusangana nepamusoro-tembiricha inodiwa uku ichideredza mitengo.
Kune reactive metal castings:zvakadai sealuminium alloys uye magnesium alloys (iyo inonyanya kushandiswa uye nyore nyore kuita neSiO₂ mujecha re quartz kuti iite inclusions), mullite sand's chemical stability inogona kuderedza reactivity uye kudzivirira kuumbwa kwe "oxidation inclusions" mukukanda.
Kune yakakura chaiyo castings:semhepo turbine giya bhokisi dzimba (inogona kuyera matani akati wandei), iyo mold shell inoda yakakwira simba rechimiro. Iyo yekutsigira layer inoumbwa ne mullite jecha uye binder ndeyekusimba kwepamusoro, inoderedza njodzi yekuwedzera mold uye kudonha.
4. Kusanganiswa nemamwe maRefractory Materials
Mukugadzirwa chaiko, jecha remullite rinowanzoshandiswa pamwe chete nezvimwe zvinhu kukwirisa mold shell performance:
Kusanganiswa nejecha zircon:zircon jecha rinoshandiswa seyepamusoro layer (kuve nechokwadi chepamusoro pepamusoro pekupedzisira) uye mullite jecha seyaitsigira layer (kudzikisa mutengo). Izvi zvakafanira castings ane zvakanyanyisa pamusoro pepamusoro zvinodiwa, senge aerospace zvikamu.
Yakasanganiswa nejecha requartz:Pamakanda ane tembiricha inodiwa (senge copper alloy, melting point 1083 ℃), inogona kutsiva jecha requartz uye kushandisa kuwedzera kwakadzika kwejecha remullite kuderedza kutsemuka kwegoko.
