Details：
First、the new material cellular ceramic products, the environmental
industry, industrial emissions, waste water purification, waste
incineration facilities until the core components, is also heat
exchangers, regenerator, energy-saving oven, gas stove,
refrigerator deodorant Equipment, paint and other energy-saving
deal with charter flights from environmentally friendly products
and materials of choice, over the years the series of products in
bulk to the United States, Germany, Korea, Japan and other
developed countries.
Ceramic honeycomb as a regenerator, mainly for heat recovery unit
in the RTO.
Ceramic honeycomb as a catalyst support, mainly for automobile
exhaust purification, air to smell, such as vehicle exhaust
catalytic converters wait.
As a ceramic honeycomb filter in, mainly for food, environmental
protection and metallurgical industries wait for the gas in the
particulate filter, metal melting in the body of impurities or
bubbles, and various industrial emissions of dust filters.
