The cement fiber pressure board is a kind of new building materials, based on the industrial standards of national building materials, it belongs to non-asbestos and chrysotile fiber cement boards in building boards. Currently in domestic, chrysotile fiber cement board takes the priority. By adopting the special production technology, the main fabrics (serpentine)、cement（portland cement)、ganister sand and other auxiliary materials which get through slurry making、extraction (or slurry flowing)、pressurization (dwt press)、four-step curing to produce the cement flat board used for construction, and it’s widely used for construction field and other various fields by its superior properties.
