Mitundu ya Reaction Bonded Silicone Carbide (RBSiC/SiSiC)

Mitundu YamachitidweBonded Silicone Carbide (RBSiC/SiSiC)

Pakadali pano, pali ambiri opanga kuti apereke zinthu za Reaction Bonded SIC kumafakitale osiyanasiyana. Shandong Zhongpeng Special Ceramics Co., Ltd iyenera kukhala imodzi mwazinthu zabwino kwambiri zopangira zinthu zosiyanasiyana za Reaction Bonded SIC, monga Nozzle ndi ena mumagetsi, zoumba, ng'anjo, chitsulo ndi chitsulo, mgodi, malasha, alumina, mafuta, mankhwala. , desulphurization yonyowa, kupanga makina, ndi mafakitale ena apadera padziko lapansi.

The Reaction Bonded SIC ikhoza kugawidwa kukhalareaction-bonded silicon carbidendireaction-formed silicon carbide, malinga ngati choyambira chili ndi tinthu tating'ono ta silicon carbide.

Rection-bonded silicon carbide

Rection-bonded silicon carbide amatanthauza njira yopangira silicon carbide composite. Zili momwemo pomwe choyambira chili ndi silicon carbide powder. Pochitapo kanthu, kaboni ndi silicon zimachita kupanga gawo latsopano la silicon carbide ndikuphatikiza ndi silicon carbide yoyambirira. Njira yokonzekera ili motere, yomwe ndi njira yomwe imagwiritsidwa ntchito kwambiri:

Kusakaniza silicon carbide ufa, mpweya ufa ndi organic binder;

Kupanga osakaniza youma ndi debonded;

Pomaliza, kupeza zomwe zimamangiriridwa silicon carbide kudzera pakulowetsa kwa silicon.

Ma silicon carbide omwe amapangidwa ndi njirayi nthawi zambiri amakhala ndi njere za silicon carbide crystal komanso zambiri za silicon yaulere. Komabe, njirayi ili ndi njira yosavuta komanso yotsika mtengo. Pakadali pano,

silicon carbide yopangidwa ndi Reaction

Choyambira chopanda kanthu chopangidwa ndi silicon carbide chimakhala ndi carbide. Choyambira chopanda kanthu cha porous carbon chimapangidwa ndi silicon kapena silicon alloy kuti apange silicon carbide composite material. Njira iyi idapangidwa koyamba ndi Hucke. Njira ya Hucke ilinso ndi zovuta zake. Kukonzekera kwake kumakhala kovuta kwambiri. Mtengo wa njirayi ndi wapamwamba. Panthawi imodzimodziyo, mpweya wochuluka umasintha pa kutentha kwa kutentha. Izi zipangitsa kuti China iwonongeke mosavuta. Choncho, njirayi ndi yovuta kwambiri kupanga zinthu zazikuluzikulu.

Kuphatikiza apo, petroleum coke imagwiritsidwa ntchito ngati zopangira pokonzekera ma slabs onse a kaboni, kenako silicon carbide imapangidwa. Komabe, katundu wa zipangizo zokonzedwa ndi zochepa. Mphamvu zake nthawi zambiri zimakhala zotsika kuposa 400mpa. Kufanana kwa silicon carbide yomwe mwapeza sikwabwino. Chifukwa cha mtengo wotsika wa petroleum coke, mtengo wa njirayi ndi wotsika kwambiri.

Summary

Poyerekeza ndi njira zina zokonzekera za silicon carbide ceramics, reaction bonded njira ili ndi ubwino wake wapadera. Pakalipano, kafukufuku m'derali makamaka amayang'ana pa kafukufuku wa sintering ndondomeko ndi maonekedwe a mapangidwe ndi katundu wa mankhwala. Komabe, kafukufuku wokhudza kupanga opanda kanthu ndi ochepa. Ngakhale pali maphunziro ochuluka pa momwe zimagwirira ntchito pakati pawo, pali maphunziro ochepa pa permeability kinetics, momwe zimagwirira ntchito komanso kapangidwe kazinthu zamtundu wa alloying. Pali maphunziro ochepa pakukonzekera kwa zida zomwe zimakhala ndi zinthu zowongolera komanso zomangika pophatikiza kulowetsedwa kwa silicon ndi zida zina. Mfundozi zikufunikabe kuziphunzira.
