Resin yakavharwa nejecha receramic
Sintered ceramic jecha ijecha rekukanda rakagadzirwa neSHXK.Iine high refractoriness (>1800°C), diki angular coefficient (<1.1, inenge spherical), kushandiswa kweasidhi shoma (neutral material), low binder content (30% kuderedzwa kwebinder content), uye zvidimbu zvesimba rakakwirira, risina kuputika uye mamwe maitiro, akakodzera kukanda jecha (jecha rekuumbwa, jecha repakati) , jecha rakavharwa, V nzira yekukanda, yakarasika foam casting (jecha rakazara), foundry coating (ceramic sand powder), 3D kudhinda uye mamwe maitiro ekukanda.Ijecha rakasvibirira uye rinoenderana nenharaunda.
Chikamu chejecha receramic chinoshandiswa mujecha rekugadzira uye jecha repakati kuita kuti goko regomba uye ganda repakati rive nemamiriro ekudzivirira kwekushisa kwepamusoro, kuwedzera kwakaderera, kudonha kuri nyore, uye kuderera kwegasi kuburitsa, izvo zvinogona kudzivirira zvinokanganisa kuwedzeredza mukukanda.Kune macores ane maumbirwo akaomarara, anogona kubata nedambudziko rekuti kupfura jecha hakusi nyore kubatanidza.
Jecha rakazara receramic rinoshandiswa kugadzira jecha rakavharidzirwa, uye rinoshandiswazve kakawanda mushure mekugadzirisazve, izvo zvinogona kunyatso kuvandudza kunaka uye kugadzirwa kwemaitiro ekukanda, kuderedza castings scrape rate uye mutengo wekugadzira wemabhizinesi, mari yekushandiswa kwenguva refu yakaderera pane iyo. ye silica sand.Naizvozvo, mumakore achangopfuura, anenge ese mahombe akafukidzwa zvirimwa zvejecha zvakashandisa jecha receramic sejecha mbishi kugadzira jecha rakavharwa.
Advantage
● Resin yakavharwa nejecha receramic ine super high tembiricha kuramba, yakasimba kuramba deformation kusimba, yakaderera inflation, yakaderera gasi shanduko, kuzadzisa zvakakosha zvinodiwa vatengi.
● Yakanaka fluidity inozadza kugona, isina-tsvimbo mold, inoshanda kune yakagadzirwa core-making process.
● Super tembiricha inodzivirira inogona kudzivirira kukanda kuremara sekupisa jecha, kupetwa kwepamusoro, tsinga, kupenya kwemajoini uye kutsemuka.
Application
Injini cylinder block, silinda musoro, piston mhete, mafuta chisimbiso, pasi chitubu.
Diki nepakati-stainless simbi, simbi yekukanda goko, off-core.
Inoshandiswa muhombe turbine shell mold, 6-8 yekumhanyisa gearbox, chikamu chikuru che auto brake disc.
Muti-cylinder block (isina flip type core), iyo pombi yekuburitsa uye bronchus.
Camshaft, chisimbiso chemafuta, ganda rekona yekona.
Ese marudzi emhando yepamusoro, yakakwirira inodiwa, yakaoma maitiro eyakavharwa jecha castings.
Zvikamu zveParticle size Distribution
Iyo particle size yekugovera inogona kugadzirwa zvinoenderana nezvaunoda.
