strong structure long lifetime lightweight waterproof fiber cement
board production line
Production conditions
1. Fiber cement board is made from Cement, quartz sand and certain
amount of fiber. It is produced after several procedures such as
pulp preparation, forming, autoclaving, drying, polishing and
after-processing.
2. It has advantages such as light in weight, high in strength,
good in processing and easy in decorating, and it can also has
performances of heat insulation and fire fighting.
3.It can be widely used in inner wall and suspended ceiling of
buildings, sound panel and partition board partition board of
gymnasium, theater and council chamber.
4. It can also be used for special facilities in various
industries, such as sound proof wall and apron plate of highway,
permanent moulding board of constructional engineering, bay plate
of train and ship, movable board for house and outer board of
large-scale clad plate factory.
