XINTAO Honeycomb Ceramic
Introduction:
Honeycomb ceramics are a new kind of industrial ceramic product developed in recent years. They have a large surface area, higher air vent rate, good heat functions, stable chemical properties etc. At present, ceramic honeycombs are being used to purify industrial waste gas, automobile emissions, eliminate noise, deal with waste water, to dry air, incineration, used in the manufacture of infrared ray instruments, to filter metal liquids etc. All ceramic honeycombs can be produced in conformance with customer requests.
