High Alumina Insulation Ceramic Board
Production Introduction
HENGRUI High temperature energy saving Company is specialized in silica alumina ceramic fiber refractory material, which have done R&D for high temperature and energy saving materials since established. The high alumina ceramic fiber board is researched, developed & tested many times by our company according to the special request for refractory materials of some parts in thermal equipment.
HENGRUI high alumina ceramic fiber board is light weight, thin sheet refractory materials, which component is Al2O3 and SiO2, etc. All the material mixed together in certain proportion and then filtered and vacuum pressed. On the surface of board there is hard protection shield condensed by different kinds of refractory powder. The shield is made evenly by our technician by special equipment on board surface to make sure its balance hardness on each part.
HENGRUI high alumina ceramic fiber board has the advantage of good hardness, low shrink, anti-erosion, long usage, no powder and so on. The high mechanical strength and excellent thermal shock resistance make the board don't drop powder and cracked on the condition of sharp quenching &snap heat and high temperature airflow.
