Pilikia Corundum-Hengli

Hana ʻia ʻo Hengli Corundum Bricks mai ke kiʻekiʻe maʻemaʻe tabular alumina, fused alumina, sintered i loko o ka wela wela kiln. Loaʻa i nā pōhaku lepo nā hiʻohiʻona o ke kiʻekiʻe kiʻekiʻe, ka maʻemaʻe kiʻekiʻe, ka porosity haʻahaʻa, a me ke kūpaʻa haʻalulu wela maikaʻi.
Hiki i nā pōhaku lepo ʻo Hengli Corundum ke kū i ka hoʻouka ʻana i ka corrosion i ka hoʻoheheʻe ʻana i nā lewa a me ka hoʻohaʻahaʻa nui ʻana i nā lewa. Hiki iā ia ke pale aku i ke kiʻekiʻe wela hydrogen hoʻouka.
Loaʻa ʻia ʻo Hengli Corundum Brick i nā nui brick maʻamau (pololei, arches a me nā wedges) a me nā papa maʻamau a me nā ʻano.

Nā hiʻohiʻona

ʻO nā pōhaku lepo Corundum, i kapa ʻia ʻo nā pōhaku alumina, he mau huahana refractory kiʻekiʻe-alumina me nā hiʻohiʻona nui.

1. **Maemae Kiekie: **ʻOi aku ka nui o ka 90% alumina (Al2O3), e hōʻoia ana i nā waiwai refractory maikaʻi loa.

2. **Ke Kūʻai Kūlana Kiʻekiʻe: **Hiki iā ia ke pale i nā mahana a hiki i 1900 ° C, e kūpono ana iā lākou no nā kaiapuni wela kiʻekiʻe.

3. **Ka Ikaika Mechanical: **Loaʻa i nā pōhaku Corundum ka ikaika compressive kiʻekiʻe a me ke kūpaʻa ʻaʻahu maikaʻi, hiki iā lākou ke mālama i nā ukana kaumaha a me nā kūlana abrasive.

4. **Paʻa ʻino: **Kūʻē lākou i ka ʻino mai nā slags, acids, alkalis, a me nā kemika ʻē aʻe, e hoʻolōʻihi i ko lākou ola ʻana i nā wahi paʻakikī.

5. **Ka Haʻahaʻa Porosity: **ʻO ka porosity haʻahaʻa e kōkua i ka pale ʻana i ka infiltration o nā mea hoʻoheheʻe a me nā kinoea, hoʻonui i ka lōʻihi a me nā waiwai insulation thermal.

6. **Kupaa wela: **Hōʻike lākou i ke kūpaʻa wela maikaʻi loa a me ke kūʻē ʻana i ka haʻalulu wela, he mea koʻikoʻi ia no nā kaʻina hana e pili ana i nā loli wikiwiki.

7. **Paʻa ʻĀpana: **ʻO ka ʻike alumina kiʻekiʻe e hōʻoia i ka mālama ʻana o nā pōhaku i ko lākou ʻano a me ka leo i nā wela kiʻekiʻe, e pale ana i ka hāʻule ʻole o ke kūkulu ʻana.

ʻO kēia mau hiʻohiʻona e hana i nā pōhaku lepo corundum i kūpono no ka hoʻohana ʻana i nā noi wela kiʻekiʻe, e like me nā kapuahi pahū, nā umu wela wela, nā ipu kila, a me nā umu ʻoihana a me nā kiln.

Hoʻohana maʻamau

Hoʻohana nui ʻia i nā ʻoihana e like me ka fertilizer, electro ceramics, petrochemical, steel, foundry, alloy steel, refractories, etc.
