Refractory clays insulating firebricks/good thermal insulation bricks:are made of Mullite material in good purity.In order to meet the thermal and physical requirements,we produce BJM insulating firebricks into several grades through the addtion of alumina.And we also add some material (which will burns out) to get the pole structure which is helpful for the heat thermal. This kind product used for oven/ furnace and some equipments working in high temperature by back-up insulation behind other refractories.The production of these goods are strictly in size and quality.
Advantages of Refractory clays insualting firebricks/good thermal insulation bricks:
• Made of high pure material,light weight • Color pure white • Good thermal conductivity • Great thermal shock resistance • very good volume stability at high temperature |
