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. Kiekie haawe softening wela.
5. Hiki ke hōʻemi i nā haumia ʻino.
6. He maikaʻi ke kū'ēʻana i ka wela.
Hoʻohana ʻia ʻo Andalusite Brick
ʻO nā paia kapuahi wela, nā pōhaku lepo, nā hale kapuahi, nā keʻena puhi ahi (andalusite low creep series)
ʻO 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.
