Koho ʻo Hengli Bubble Alumina Bricks ma ke ʻano he alumina maʻemaʻe kiʻekiʻe ma ke ʻano he kumu nui, ʻo ka pauka micro waiwai kiʻekiʻe ma ke ʻano he mea hoʻohui, nā mea kūlohelohe e like me ka mea hoʻopaʻa pōkole, i hoʻopaʻa ʻia i ke kiln kaʻa wela kiʻekiʻe. Loaʻa i nā huahana i hoʻopau ʻia ka nui o ka pore pani ʻia, loaʻa nā ʻano o ke kaumaha māmā a me ke kūpaʻa wela kiʻekiʻe, ka conductivity thermal haʻahaʻa, ka ikaika kiʻekiʻe, ka liʻiliʻi liʻiliʻi reheating linear hoʻololi, ke kūpaʻa haʻalulu maikaʻi maikaʻi, ke kūpaʻa erosion maikaʻi i ke kinoea erosive & melting slag.
Hiki i ka Bubble Alumina Bricks ke hoʻomaikaʻi maikaʻi i ka wela wela o ka umu, hoʻopōkole i ka pōʻai hana, hoʻomāmā i ke kaumaha o ka umu a ʻike i ka mālama ʻana i ka ikehu.

Nā hiʻohiʻona

He mau hiʻohiʻona ʻokoʻa nā pōhaku alumina bubble:

1. **Hoʻokohu wela kiʻekiʻe**:ʻO kā lākou haʻahaʻa haʻahaʻa haʻahaʻa e hoʻolilo iā lākou i insulators maikaʻi loa, e hōʻemi ana i ka nalowale o ka wela ma nā wahi wela kiʻekiʻe.

2. **Maʻemaʻe Kiʻekiʻe**:Hana ʻia mai ka alumina maʻemaʻe kiʻekiʻe, hāʻawi kēia mau pōhaku i ka hana ʻoi aku ka maikaʻi ma nā kūlana koʻikoʻi.

3. **Māmāmā**:ʻO ka hoʻohui ʻia ʻana o nā puʻupuʻu alumina e hōʻemi i ka nui o ka nui, e hoʻomāmā a maʻalahi hoʻi i nā pōhaku lepo.

4. **Ku'e i ka Mahana Kiekie**:Hiki iā lākou ke pale i nā wela kiʻekiʻe loa, ʻoi aku ma mua o 1800 ° C, i kūpono no ka hoʻohana ʻana i nā umu wela a me nā kiln.

5. **Paʻa ʻino**:He kūpaʻa maikaʻi ko lākou i ka hoʻouka ʻana i nā kemika, ʻoi aku ka nui o nā slags a me nā metala hoʻoheheʻe.

6. **Hoʻonui wela haʻahaʻa**:Kōkua kēia hiʻohiʻona i ka mālama pono ʻana i ke kūkulu ʻana a hōʻemi i ka pilikia o ka haki ʻana ma lalo o ka paikikala wela.

7. **Ka Ikaika Mechanical**:ʻOiai he māmā, hāʻawi lākou i ka ikaika mechanical maikaʻi a me ka lōʻihi ma lalo o nā kūlana hana.

Hoʻohana pono kēia mau hiʻohiʻona i nā pōhaku alumina bubble i nā ʻoihana e like me ka metallurgy, ceramics, a me ka hana aniani.

Hoʻohana maʻamau

Hoʻohana nui ʻia i nā ʻoihana e like me ka metallurgical, refractories, ceramics, petrochemical, aniani, uila, etc. Hiki ke hoʻohana ʻia ʻo ia e like me ke alo wela o ka pale ʻana o ka pyrolizer, ka umu wela wela, ka umu ahi, ka tunnel kiln, ka pahu pahu kīwī, ke kapuahi crucible. , kapuahi uila, etc.
