Kufotokozera
Kampani yathu imaperekaKupaka kwa SiCntchito ndi CVD njira pamwamba pa graphite, zoumba ndi zipangizo zina, kuti mpweya wapadera munali mpweya ndi pakachitsulo anachita pa kutentha kupeza mkulu chiyero SiC mamolekyu, mamolekyu waikamo pamwamba pawokutidwazipangizo, kupanga SIC zoteteza wosanjikiza.
Makhalidwe a SiC shawa mitu ndi motere:
1. Kukana kwa dzimbiri: Zinthu za SiC zimakhala ndi kukana kwa dzimbiri ndipo zimatha kupirira kukokoloka kwa zakumwa zamadzimadzi zosiyanasiyana ndi njira zothetsera, ndipo ndizoyenera kugwiritsa ntchito njira zosiyanasiyana zopangira mankhwala komanso njira zochizira pamwamba.
2. Kukhazikika kwa kutentha kwakukulu:SiC nozzlesamatha kukhala okhazikika m'malo otentha kwambiri ndipo ndi oyenera kugwiritsa ntchito zomwe zimafuna chithandizo cha kutentha kwambiri.
3. Kupopera mbewu kwa yunifolomu:SiC nozzlekapangidwe ali wabwino kupopera mphamvu ntchito, amene angathe kukwaniritsa yunifolomu kugawa madzi ndi kuonetsetsa kuti mankhwala madzi wogawana anaphimba pamwamba chandamale.
4. Kukana kuvala kwakukulu: Zida za SiC zimakhala ndi kuuma kwakukulu ndi kukana kuvala ndipo zimatha kupirira kugwiritsa ntchito nthawi yayitali ndi kukangana.
Mitu ya shawa ya SiC imagwiritsidwa ntchito kwambiri muzamankhwala amadzimadzi popanga semiconductor, kukonza mankhwala, zokutira pamwamba, ma electroplating ndi magawo ena ogulitsa. Ikhoza kupereka zotsatira zokhazikika, zofananira komanso zodalirika zopopera mankhwala kuti zitsimikizire ubwino ndi kusasinthasintha kwa processing ndi chithandizo.
Main Features
1. Kutentha kwakukulu kwa okosijeni kukana:
kukana kwa okosijeni kumakhalabe kwabwino kwambiri pamene kutentha kumafika pa 1600 C.
2. Chiyero chachikulu: chopangidwa ndi kuyika kwa nthunzi wamankhwala pansi pa kutentha kwambiri kwa chlorination.
3. Kukana kukokoloka kwa nthaka: kuuma kwakukulu, pamwamba, tinthu tating'onoting'ono.
4. Kukana kwa dzimbiri: asidi, alkali, mchere ndi organic reagents.
