It is the mainstream in the form of its numerous advantage has become wall thermal insulating.Currently, in outer heat preservation system, material used in insulating layer
Presently mainly polystyrene expansion plate (EPS), extruded sheet (XPS), polyurethane sheet, although its thermal coefficient is lower, Ke Yiman
The existing energy-efficient requirement of foot, but there is serious fire safety evaluating hidden danger, it is brought greatly to people's lives and property
It threatens.The production and application for greatly developing especially A grades of fire-type energy-saving building materials of novel energy-saving construction material are to ensure people
The needs of people's safety of life and property, and the emphasis of construction technique development from now on.
The inorganic material such as pearlite insulation plate, rock wool board, foamed cement board and the glass fibre cotton applied at present have
There is certain thermal insulation property, is often used as thermal insulation material.Take perlite as the heat preservation slurry and plate of basic raw material, there is fire prevention
The advantages that performance is good, thermal insulation property is good, low in cost and easy for construction meets current architectural exterior insulation material and is necessary for A grades
The requirement of material.But perlite plate thermal coefficient, generally 0.06 or more, bulk density is in 300kg/m3, to reach same section
It can require, the thickness of perlite plate is approximately twice of organic insulation material thickness, and panel weight used is about organic heat-insulating plate
20~30 times of the weight of material, under this brings all wall constructional difficulties as above and plate easy to the practical application of pearlite insulation plate
Many problems such as pendant.At present with inorganic fireproofing insulation material that perlite is basic raw material there are still heat insulation effects poor, bulk density compared with
Greatly, the disadvantages of the problems such as easily broken, bad mechanical strength, nail-holding ability are poor and difficulty of construction is big.Rock wool has heat insulating ability and fire prevention etc.
The advantages that grade is high, is a kind of A grades of heat preservation plate materials being commonly used, but this kind of plate there is also production energy consumptions big, the easy moisture absorption,
The disadvantages of difficulty of construction is big, intensity is extremely low can generate easily tenesmus, under surface mortar is easy to fall off and thermal insulation property in use
The problems such as serious, drops.Foamed cement has many advantages, such as processing at low cost, easy to produce, and fire protecting performance is A grades, can be used as architecture indoor
Wall is filled, is used in recent years used also as thermal insulation material, but it belongs to fragile material, difficulty of construction is big and weatherability is poor.Cause
This, at present there are some disadvantages for being difficult to overcome when applying on building heat preservation in inorganic heat preservation plate.
