What is the difference between wear resistant castables and wear-resistant plasticrefractory?
Wear-resistant castables and wear-resistant plastic refractory are both wear-resistant refractory materials, but they are quite different.
Wear-resistant castables: brown corundum, silicon carbide, and bauxite are the main raw materials, which are combined with 1-12mm aggregates, powders and pure calcium aluminate cement. They have strong resistance to wear and corrosion. Quite strong.
Wear-resistant plastic refractory also need corundum, silicon carbide, and bauxite as the main raw materials, which are made by adding 0-5mm particles into refractory clay with strong cohesiveness and combining with phosphoric acid.
Wear-resistant castables and wear-resistant plastic refractory are very different in construction form. When the wear-resistant materials are constructed, the thickness is more than 100mm. Generally, the construction thickness is 200mm. The wear-resistant castable and bonding agent are poured into the mixer. Adding water and stirring requires pre-welding anchor nails, anchor bricks and other supporting parts, and then supporting the mold for pouring construction. During the construction, the castable is vibrated and compacted with a vibrating rod. After the castable is solidified, the template is removed, and then dried for curing and put into use.
The wear-resistant plastic refractory material needs to be trapped before construction. There is no need to set up templates, and tortoise shell nets or anchors are used as support. Put the plastic into the pores of the support and ram it to make it compact. And in the construction process, the material should not be in contact with water, and the waterproof work should be done well in the plastic construction. And the construction thickness of the plastic is 50-80mm, not more than 80mm.
If the wear-resistant plastic refractory is not applied in a short time, the binder and the aggregate can be installed separately. When using, add half of the binder to the mixer for mixing. After the material is trapped for 12 hours, add the other half of the binder. Stir before use. If the construction time is tight, you can first add 40% of the bonding agent to the manufacturer. The plastic has already been trapped during transportation, and then another part of the bonding agent is added to the construction site, and the construction can be carried out at any time.
There are 4 biggest differences between wear-resistant castables and wear-resistant plastic refractory. The first is the difference in bonding agent, the second is the size of the aggregate, the third is the construction method, and the fourth is the construction. The thickness is different.
