TECHNICAL FIELD

[0002] The high-pressure vacuum extrusion forming plate, referred to as ECP plate for short, is a hollow strip plate made of silicate cement, fibers (pulp fiber, polypropylene fiber, etc.), and siliceous materials (quartz powder, etc.) as main raw materials, and is made through vacuum high-pressure extrusion forming, once low-temperature steam curing, and high-temperature and high-pressure curing.

[0003] The ECP plate has many advantages, including: (1) high strength: the ECP plate has very high strength after high-temperature and high-pressure curing, with a bending strength of 17 MPa, a solid compressive strength of 60 MPa, and a hollow compressive strength of greater than 10 MPa; (2) light weight: the ECP plate has a relatively light weight, for example, the areal density of a 60 mm thick plate is 70-75 kg / m2, which can reduce the load requirements on the structure and foundation and facilitate construction; (3) high weather resistance: the plate structure is dense, the performance is stable, the surface water absorption rate is low, and the freeze-thaw cycle can reach 100 times, so the ECP plate has excellent durability and weather resistance; (4) excellent fire resistance: the ECP plate is a non-combustible material of A1 grade, and the fire resistance limit of a 60 mm thick plate is 1 hour, meeting the building fire performance requirements; (5) good sound insulation performance: the ECP plate has excellent sound insulation performance, for example, the sound insulation performance of a 60 mm thick plate can reach 32 dB, and the sound insulation performance of an 80 mm plate reaches 36 dB. Therefore, the ECP plate is widely used in the building industry.
