ʻO nā mea hoʻomehana Silicon Carbide SiC

ʻO ka wehewehe pōkole:

Hoʻopili ʻia ka mea hoʻoheheʻe silikoni me ka oxide metala, ʻo ia hoʻi, ka pena infrared lōʻihi silikon carbide pā ma ke ʻano he radiation element, i loko o ka lua element (a i ʻole groove) i loko o ka uea hoʻomehana uila, ma ka lalo o ka silicon carbide plate e hoʻokomo i ka insulation mānoanoa, refractory. , mea wela wela, a laila hoʻokomo ʻia ma ka pūpū metala, hiki ke hoʻohana ʻia ka pahu e hoʻopili i ka lako mana.

Ke hoʻomālamalama ka hihi infrared lōʻihi o ka mea hoʻomehana silicon carbide i ka mea, hiki iā ia ke komo, noʻonoʻo a hele i loko. Hoʻopili ka mea wela a maloʻo i ka ikehu radiation mamao-infrared i kahi hohonu o nā molekole kūloko a me ka ʻili i ka manawa like, e hana ana i kahi hopena hoʻomehana ponoʻī, i hoʻoheheʻe ʻia ka mea hoʻoheheʻe a i ʻole ka wai molekele a wela like, pēlā e pale aku ai i ka deformation a me ka hoʻololi qualitative. ma muli o nā degere like ʻole o ka hoʻonui ʻia ʻana o ka wela, no laila e mau ke ʻano o ka mea, ke kino a me nā waiwai mechanical, ka wikiwiki a me ke kala.

ʻoi aku ka maikaʻi o ka pale ʻana i ka oxidation ke kiʻekiʻe ka mahana e like me 1600 C.
2. Maʻemaʻe kiʻekiʻe: hana ʻia e ka hoʻoheheʻe ʻana i ka mahu ma lalo o ke kūlana chlorination kiʻekiʻe.
3. Erosion kū'ē: kiʻekiʻe paakiki, paʻaʻiliʻili, maikaʻi particles.
4. Ke kū'ē i ka corrosion: acid, alkali, paʻakai a me nā mea hoʻoulu.
