Paʻa paʻa, wai a ʻaʻahu kūʻokoʻa, mea ʻenehana silica graphite hou

ʻO ka wehewehe pōkole:

ʻO Ningbo VET Energy Technology Co., Ltd. he ʻoihana ʻenehana kiʻekiʻe i hoʻokumu ʻia ma Kina. ʻO mākou he mea hana loea a me ka mea hoʻolako i nā huahana silicide Graphite.

ʻO ka graphite silikoni kahi mea i hoʻopili ʻia i hoʻopili ʻia ka carbide silika i ka ʻili o kahi substrate graphite. Loaʻa iā ia nā hiʻohiʻona o ka paʻakikī kiʻekiʻe, ka ikaika mechanical kiʻekiʻe a me ke kūpaʻa ʻana o ka carbide silicon, a me nā waiwai lubricating ponoʻī a me ke kūpaʻa haʻalulu wela o ka graphite. ʻO ia nā mea friction kūpono a me nā mea mechanical seal, kūpono no ka hoʻopaʻa ʻana i nā mīkini wai like ʻole, nā ʻaila ʻaila, nā pahū kemika, a me nā bearings o nā ʻano ʻano nui o ka wikiwiki a me ka ukana nui. Eia hou, siliconized graphite i maikai oxidation kū'ē, thermal shock kū'ē, haʻahaʻa porosity, a me kekahi uila conductivity, a hiki ke hoʻohana 'ia e like me metala smelting crucibles a me ka huki paipu.

ʻO ke ʻano o ka siliconizedʻAʻahu like ka graphite, kūlike ka ʻili me ka loko, a hiki ke hoʻololi ʻia ka lakene o ka carbide silicon a me ka graphite. ʻOi aku ka kiʻekiʻe o ka ʻike o ka silicon carbide, ʻoi aku ka nui o ka nui o ka mea, ʻoi aku ka kiʻekiʻe o ka ikaika compressive, a piʻi ka resistivity.
