Andalusite Brick-kope-kope
ʻO ka wehewehe ʻana o Andalusite Brick
ʻO nā mea waiwai no ka hana ʻana i nā pōhaku lepo refractory andalusite: ka pauka mullite, ka pauka maikaʻi alusite, ka pauka maikaʻi sillimanite, ka pālolo, ka pauka silika, etc.
E hoʻomākaukau i nā mea maka i luna e like me ka ratio formula, a laila e hoʻokomo i ka pauka mullite, a me ka pauka maikaʻi alusite a me ka pauka sillimanite i loko o kahi hui one no ka hui ʻana, a laila hoʻohui i ka pālolo a me ka wai e helu ana no 2% o ka nui o ke kaumaha o nā mea maka no ka hui ʻana, a laila e hoʻohui i ka pauda silika no ka hui ʻana, a e hoʻohana i ka paʻi pōhaku e kaomi i loko o kahi pākaʻi pōhaku, a ma hope o ka maloʻo ʻana o ka pā pōhaku, waiho ʻia ia i loko o kahi kīʻaha ahi no ka sintering, ʻo ia hoʻi, ke puhi ʻia i loko o nā pōhaku lepo refractory andalusite.
Nā ʻāpana Brick Andalusite
ʻO ka hana o nā brick Andalusite
1. ʻO ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa a me ka pale ʻana i ka corrosion.
2. ʻO ke kūpaʻa haʻalulu wela maikaʻi.
3. Haʻahaʻa kolo kolo.
4. Kiʻekiʻe haawe softening wela.
5. Hiki ke hōʻemi i nā haumia ʻino.
6. Kūleʻa maikaʻi ka wela spalling.
Hoʻohana ʻia ʻo Andalusite Brick
ʻO nā paia kapuahi wela, nā pōhaku lepo, nā hale kapuahi, nā keʻena puhi ahi (andalusite low creep series)
Nā pōmaikaʻi o nā brick Andalusite no nā kapuahi wela wela:
1. ʻO ka mea mua, hoʻonui ia i ke ola lawelawe o ka umu wela wela a hoʻomaikaʻi i nā pono waiwai no ka ʻoihana.
2. Hoʻonui ka paʻa haʻalulu maikaʻi i ke ola lawelawe o ka lining kiln a hoʻemi i ka lilo o ka hui ma nā mea refractory.
3. Hoʻololi pono i ka pilikia o ka instability o nā pōhaku lepo refractory ʻē aʻe ma ke ʻano wela wela o ka umu wela.
