Corundum refractory plastic mouldable

Corundum refractory plastic mouldable,The main materials of this product is corundum , carborundum and super high bauxite ,matched with superfine powder , adopt combined binder and additive and plasticizer to match. It has good plasticity ,long-time storage life and its strength will increase along with the temperature’s increasing to ensure the mouldable refractory high strength and wear-resistance. The wear-resisting mouldable refractory we developed was included as science promotion project by Henan province technology department .its character is convenient construction , quick repair, high strength wear-resisting , good thermal shocking, no cracking and good sealing which is suitable for the liner construction and quick repair of CFB boiler.

Application of Corundum refractory plastic mouldable :
Refractory plastics can be used to patch or repair worn refractory areas whether they were originally brick castable or plastic. For the best results, the worn refractory should be removed back to a sound surface, removing loose material and preferably providing V-shape surfaces that will allow good bonding of the patch to the original refractory. A bonding mortar coating aids in achieving a lasting patch with good adherence . Zhengzhou dongfang refractory material co.,ltd manufactures many types of plastic refractories designed for original installations and patches and for compatibility with the application conditions.
