Zvidhinha Zvinopisa Zvinogona Kutsungirira Kupisa Kwakakwirira Zvakadini?

Zvidhinha zvinogara zvichiramba:Kana ukangofunga nezvemutengo chete, unogona kusarudza zvidhinha zvakachipa zvinoramba kushandiswa, zvakaita sezvidhinha zvevhu. Chidhinha ichi chakachipa. Chidhinha chinongodhura $0.5~0.7/block chete. Chine mashandisirwo akasiyana-siyana. Zvisinei, chakakodzera kushandiswa here? Kana chiri chinodiwa, kana chikasazadzikiswa, chinogona kukonzera kugadziriswa nguva nenguva nekuda kwekusakara, uye chingasakwanise kushandiswa zvakajairika. Kugadziriswa kwacho kakawanda kunogona kutungamira mukugadziriswa nekukurumidza uye kutokuvadza michina, izvo zvisina kukodzera kuwana mari.
Zvidhinha zvevhu zvinhu zvisina acid yakawanda, zvine huremu hwemuviri hunosvika 2.15g/cm3 uye huwandu hwealumina hwe ≤45%. Kunyangwe kusimba kwekudzivirira kuri pa1670-1750C, kunonyanya kushandiswa pakupisa kwakanyanya kwe1400C. Chigadzirwa ichi chinogona kushandiswa chete zvichienderana nezvinodiwa. Kupisa, zvimwe zvikamu zvisingakoshi, kusimba kwekumanikidza kwezvidhinha zvevhu hakuna kukwira, 15-30MPa chete, izvi zvine chekuita nezviratidzo zvechigadzirwa, ndicho chikonzero nei zvidhinha zvevhu zvakachipa.

Zvidhinha zvine alumina yakawanda zvinoramba kushanda:Zvidhinha zvealumina zvine magiredhi mana zvichibva paalumina. Nekuti huwandu hwealuminamu muzvinhu zvakagadzirwa hwakakwira kupfuura hwezvidhinha zvevhu, zita rekuti zvidhinha zvealumina zvine magiredhi akawanda rinobva pane izvi. Zvichienderana negiredhi, chigadzirwa ichi chinogona kushandiswa pakupisa kwakanyanya kubva pa1420 kusvika 1550°C. Kana chikashandiswa, chinogona kuiswa pamoto. Simba rekudzvanya tembiricha yakajairika rinosvika 50-80MPa. Kana chikaiswa pamoto, tembiricha yepamusoro haigone kukwira kupfuura tembiricha yekushanda. Izvi zvinonyanya kukanganiswa nehuremu hwechigadzirwa uye huwandu hwealuminamu.

Zvidhinha zvakawanda:Zvidhinha zveMullite zvinoramba kusimba zvine simba guru uye tembiricha yepamusoro yekushanda. Zvinowanikwa mumhando dzakareruka uye dzakaoma. Zvidhinha zveMullite zvinorema zvinosanganisira zvidhinha zveMullite zvakasanganiswa uye zvidhinha zveMullite zvakasinwa. Kudzivirira kupisa kwechigadzirwa ichi kwakanaka; zvigadzirwa zvakareruka zvine simba rakanaka rekudzivirira kupisa. Zvigadzirwa zvakareruka ndeizvi: JM23, JM25, JM26, JM27, JM28, JM30, JM32. Zvigadzirwa zveMullite zvinoramba kusimba zvinogona kupiswa nemoto, uye maburi anogoverwa zvakaenzana. Zvichienderana nehukuru hwechigadzirwa uye huwandu hwezvinhu zvakabikwa, JM23 inogona kushandiswa pasi pe1260 degrees, JM26 pasi pe1350 degrees, uye JM30 inogona kushandiswa patembiricha yepamusoro ye1650 degrees. Ichi ndicho chikonzero nei zvidhinha zveMullite zvichidhura.

Zvidhinha zveCorundum:Chidhinha cheCorundum chidhinha chinorasika chemhando yepamusoro chine alumina inopfuura 90%. Chigadzirwa ichi chinewo zvigadzirwa zvakasimwa uye zvakasanganiswa. Zvichienderana nezvinhu zvakagadziriswa, zvigadzirwa zvinosanganisira: chidhinha chezirconium corundum chakasanganiswa (AZS, chidhinha chakasanganiswa), chidhinha chechromium corundum, nezvimwewo. Simba rekudzvanya tembiricha yakajairika rinodarika 100MPa uye rinogona kushandiswa kwenguva yakareba munzvimbo ine tembiricha yakakwira ye1,700 degrees. Mutengo wechidhinha ichi chinorasika unosiyana kubva pazviuru zvakati wandei kusvika kumakumi ezviuru zveyuan patani nekuda kwezvinhu zvakaita semaitiro ekugadzira uye huwandu hwezvinhu zvakagadziriswa.

Zvidhinha zveAlumina zvisina chinhu:Zvidhinha zveAlumina hollow ball zvidhinha zvinodhura zvine mwero, zvinodhura kusvika paRMB 10,000 patani. Nekuda kwenzvimbo dzakasiyana dzekushandiswa uye maitiro ekugadzira, kusanganisira huwandu hwealumina, nezvimwewo, mutengo wechigadzirwa unofanirwa kunge wakakwira. , sezvinotaurwa, kukosha kwemari.

Zviri pamusoro apa zvinotiratidza huwandu hwezvinhu zvinoramba kushanda, kuramba kupisa kwakanyanya uye mutengo wezvidhinha zvinoramba kushanda. Kazhinji, huwandu hwezvinhu zvinoramba kushanda hunoyerwa usati wabuda mufekitori. Huwandu hwezvinhu: hunoratidza huwandu hwehuremu hwechigadzirwa chakaoma kusvika pahuwandu hwacho hwese, hunoratidzwa mu g/cm3.
