China inopenya isina musono zirconium crucible yekunyungudutsa simbi Mugadziri uye Mutengesi

inopenya isina musono zirconium crucible yekunyungudutsa simbi

Tsanangudzo Pfupi:

Bright seamless zirconium crucibles yekunyungudusa simbi ingave sarudzo yakanakisa kune yakanyanya tembiricha yekushandisa. Zirconium inozivikanwa nepamusoro pekunyunguduka kwayo uye kusagadzikana kwekuora, zvichiita kuti ive yakakodzera kushandiswa mukuita kunyungudika kwesimbi.

Ndeipi tembiricha yemhando ye zirconium crucibles?

Zirconium crucibles ine tembiricha yakakwira, ichiita kuti ive yakakodzera kune akasiyana maindasitiri ekushandisa anosanganisira kunyungudika kwesimbi uye mamwe maitiro ekupisa. Tembiricha yemhando ye zirconium crucibles inowanzo wedzera kubva mukamuri tembiricha kusvika kunosvika 2400 ° C (4352 ° F). Uku kugona kwekushisa kwakanyanya kunoita kuti zirconium crucibles zvive zvakanaka pakunyungudusa masimbi akanyanya kunyungudika senge titanium, nickel nedzimwe simbi dzinoramba.

Pamusoro pezvo, zirconium's corrosion resistance uye kugona kumira tembiricha yakakwira inoita kuti ive chinhu chakakosha chekushandisa mumamiriro akanyanya.

Ndeupi musiyano uripo pakati pealumina uye zirconia crucible?

Alumina uye zirconia crucibles ese ari maviri anowanzo shandiswa mukupisa kupisa kwepamusoro, asi ane mimwe misiyano yakakosha:

1. Kuumbwa kwezvinhu:
- Alumina crucibles inogadzirwa nealuminium oxide (Al2O3), chinhu checeramic chinozivikanwa nehupamhi hwekupisa conductivity uye yakanakisa makemikari kuramba.
- Zirconia crucibles, kune rumwe rutivi, inogadzirwa ne zirconium dioxide (ZrO2), inozivikanwawo se zirconia. Zirconia ine simba rakakwirira, kuoma uye kurwisana nekutyisa kwekushisa.

2. Kunyungudika:
- Aluminium oxide ine nzvimbo yakakwira yekunyungudika, kazhinji inotenderedza 2050°C (3722°F), ichiita kuti ive yakakodzera kune dzakasiyana siyana tembiricha yekushandisa.
- Zirconia ine nzvimbo yakakwirira yekunyungudika, kazhinji inotenderera 2700 ° C (4892 ° F), zvichiita kuti ive yakakodzera kune zvikumbiro zvinoda kupisa kwakanyanya.

3. Thermal conductivity:
- Aluminium oxide ine yakanyanya kupisa conductivity, iyo inobatsira mune mamwe maapplication uko kwakakosha kupisa kupisa kwakakosha.
- Zirconia ine yakaderera thermal conductivity ichienzaniswa nealuminium, iyo inobatsira mumashandisirwo anoda kupisa kwemafuta.

4. Chemical resistance:
- Aluminium oxide ine yakanaka makemikari kuramba, ichiita kuti ive yakakodzera kushandiswa nesimbi zhinji dzakanyungudutswa uye hutsinye hwemakemikari nharaunda.
- Zirconia inoratidzawo yakanakisa makemikari kuramba, kunyanya kune acidic uye alkaline nharaunda, zvichiita kuti ive yakakodzera kudiwa kwemakemikari kushandiswa.

Mukupfupisa, nepo zvese zviri zviviri alumina uye zirconia crucibles zvakakodzerwa nepamusoro-tembiricha kunyorera, sarudzo pakati pezviviri zvinoenderana nezvinodiwa chaizvo senge tembiricha renji, thermal conductivity, uye makemikari kuramba.
