Ruzivo rweChigadzirwa

Jecha reMullitechinhu chinodzivisa kuumbwa kwearuminiyamu silicate, chinowanzoshandiswa mukugadzira simbi isina ngura. Kusimba kwekudzivirira kunosvika madhigirii 1750. Kana aruminiyamu yakawanda mujecha remullite, iron yakaderera, uye guruva diki, kunaka kwejecha remullite kunowedzera. Jecha remullite rinogadzirwa nekupisa kwakanyanya kwekaolin.

Zvimiro:
1. Nzvimbo yakanyanya kunyunguduka, kazhinji pakati pe1750 ne1860°C.
2. Kugadzikana kwakanaka pakupisa kwepamusoro.
3. Kuwanda kwekuwedzera kwekupisa kwakaderera.
4. Kugadzikana kwakanyanya kwemakemikari.
5. Kugoverwa kwehukuru hwezvimedu zvine mwero kunobvumira kusarudzwa nekugadzirisa zvichienderana nemaitiro akasiyana ekukanda uye zvinodiwa zvekukanda.

Mashandisirwo

Chinhu chikuru chekukanda nemazvo inyaya yekugadzira magoko emhando ye mold (maitiro ekuputira patani ye wax nezvinhu zvakawanda zvinoramba kugadzira goko rekunze. Mushure mekunge patani ye wax yanyunguduka, panobva paumbwa gomba rekudururira simbi yakanyungudutswa). Jecha reMullite rinoshandiswa zvakanyanya sechikamu chinoramba mugoko re mold uye rinoshandiswa pazvikamu zvakasiyana zvegoko, kunyanya zvinotevera:

1. Goko Repamusoro (Rinosarudza Zvakananga Hunhu Hwepamusoro hweChigadziko)
Basa:Rutivi rwepamusoro rwuri padivi pechinhu chakaumbwa uye runofanira kuva nechokwadi chekuti simbi yakanyungudutswa inopedzwa zvakanaka (kudzivisa kukweshana uye kudonha) ukuwo ruchitsungirira kukanganiswa kwesimbi yakanyungudutswa pakutanga.

2. Goko reMusana (Rinopa Simba uye Kufema Kwazvo)
Basa:Goko rekumashure rine zvidimbu zvakawanda riri kunze kwechikamu chepamusoro. Rinotsigira simba rose regoko rechimurenga (rinodzivirira kushanduka kana kuputsika panguva yekudurura) ukuwo richivimbisa kufema zvakanaka (kuburitsa magasi kubva mugomba uye kudzivirira maburi ari mugomba).

3. Zvikumbiro Zvakanyanya zveKukanda Zvine Madiro Akawanda
Kukanda alloy inodziya zvakanyanya:zvakaita sema "turbine blades" einjini yendege (tembiricha inodururwa ye1500-1600°C), inoda kuti ganda re "mold" rikwanise kutsungirira tembiricha dzakanyanya. Kusasimba kwakanyanya kwejecha re "mullite" kunogona kutsiva jecha re "zircon" rinodhura (nzvimbo yekunyunguduka ye2550°C, asi rinodhura), richisangana nezvinodiwa zvekudzivirira tembiricha yepamusoro uku richideredza mitengo.

Kune simbi dzinoshandiswa:zvakaita searuminiyamu alloys uye magnesium alloys (izvo zvinobata zvakanyanya uye zvinobata nyore nyore neSiO₂ mujecha re quartz kuti zvigadzire inclusions), kugadzikana kwemakemikari ejecha re mullite kunogona kuderedza reactivity uye kudzivirira kuumbwa kwe "oxidation inclusions" mu casting.

Kune ma "castings" makuru nemazvo:zvakaita semabhokisi egiya remhepo (anogona kurema matani akati wandei), goko remuchina wekugadzira zvinhu rinoda simba rakawanda rekuvaka. Rutivi rwekumashure runoumbwa nejecha remullite nebinder rwakasimba, zvichideredza njodzi yekukura nekuputsika kwemuchina wekugadzira zvinhu.

4. Kusanganiswa Nezvimwe Zvinhu Zvinodzora Ruvara
Mukugadzirwa chaiko, jecha remullite rinowanzoshandiswa pamwe chete nezvimwe zvinhu kuti zviite kuti ganda remufuru rishande zvakanaka:

Kusanganiswa nejecha re zircon:Jecha rezircon rinoshandiswa sechikamu chepamusoro (kuona kuti chikamu chepamusoro chakakwirira) uye jecha remullite sechikamu chemashure (kuderedza mitengo). Izvi zvakakodzera kuzvinhu zvinogadzirwa nesimbi zvine zvinodiwa zvakanyanya pamusoro, zvakaita sezvikamu zvemuchadenga.

Yakabatanidzwa nejecha re quartz:Kune zvinhu zvinogadzirwa nesimbi zvine tembiricha yakaderera (senge copper alloy, melting point 1083℃), zvinogona kutsiva jecha re quartz zvishoma uye kushandisa mullite jecha shoma kuderedza kuputika kweganda.
