[0051] name
[0052] 3. Nano-sol combined with long-life environmental protection wear-resistant plate prepared by non-oxidizing composite powder
preparation example 1
[0054] Its components and parts by weight are: 35 parts of magnesium-aluminum spinel corundum; 25 parts of fused dense corundum; 25 parts of SiC; 8 parts of non-oxide composite powder prepared in Example 1 above; 5 parts of activated alumina micropowder , 2 parts of metal silicon powder, 6 parts of nano aluminum sol, 0.05 part of wetting agent, 0.2 part of explosion-proof fiber,
[0055] Among them, the gradation of magnesium-aluminum spinel corundum is 8mm-5mm 10 parts; 5mm-3mm 15 parts, 3mm-1mm 10 parts.
[0056] Among them, the gradation of fused dense corundum is 1mm-0.2mm, 15 parts; the particle size is ≤0.074mm, and 10 parts.
[0057] Weigh each component of the wear-resistant plate raw material according to its weight, pour it into the mixer and stir for 5 minutes, adjust the amount of nano-alumina sol to make the vibration fluidity reach 130-140mm, and then pour it into the corresponding wear-resistant plate mold. Use a vibrating rod to tamp the air holes, release the...
