What are the exterior wall insulation materials?
- Benzene plate. The price of this material is relatively cheap, because its heat preservation effect is not ideal. And after the rain will be deformed, very easy to absorb water; therefore, the use of this material usually waterproof.s
Which is better, roofing rock wool or glass wool?
- Glass wool than low density rock wool, slag ball less content, low thermal conductivity, long service life, high toughness fiber, but the maximum use temperature of high rock wool up to 600 degrees Celsius, glass wool is only 260 degrees celsius.s
Advantages of exterior wall energy saving and environmental protection heat insulation coating
- 1, rock wool board, inorganic refractory class A, thermal conductivity of 0.041-0.045, fire retardant, moisture absorption, insulation effect is poor;2, inorganic active insulation refractory grade A, thermal conductivity of 0.050-0.055 fireproof insulation effect is good, the construction is simple (no mesh, mortar etc.), and buildings with life, water resistant anti cracking hollowing;3, ceramic insulation board, inorganic refractory grade A, thermal conductivity 0.08-0.10, fire retardant, non absorbent, easy construction, durable use;s
What are the building thermal insulation materials in general?
- Qinglong hollow glass micro bead heat insulation technology is composed of hollow glass beads inorganic insulation mortar, impermeable crack mortar, alkali resistant fiberglass mesh cloth (or galvanized steel mesh) is composed of three parts, the core part is hollow bead mortar, thermal insulation mortar insulation for the past, empty valley clefts and low strength. Our company in recent years development and improvement, through the selection and adjustment of raw materials imported additives were modified to form a double micro structure inside the product, the material has the characteristics and functions of lightweight plastering mortar, excellent thermal insulation, heat insulation performance of the material is stable, excellent fireproof performance, convenient construction, is at present, the products of similar products.s
What is the difference between high-density rock wool board and hard rock wool board?
- It can be used in the area of flat and big curvature radius, such as tank, boiler, large steel structure, external thermal insulation of glass curtain wall and so on. With aluminum foil, it can meet the needs of insulation and water vapor barrier of HVAC, air duct and cooling and heating pipe, as well as the requirement of building insulation. Make the room cool in summer and warm in winter and comfortable in all seasons.s
What are the composite thermal insulation boards?
- Extrusion board, Extrusion board insulation effect is better, higher prices, but also easy to burn, complex construction process, the need to add mesh cloth.s
The difference between rock wool and mineral wool
- By the above two concepts, we should compare the difference between rock wool and slag cotton.1., raw materials are different: to metallurgical slag or fly ash as the main raw material called slag cotton; basalt and other rock as the main raw material called "rock wool"".2. the coefficient of acidity of rock wool and slag cotton is also different. Rock wool acidity coefficient MK generally greater than 1.5, and even up to more than 2; slag cotton MK generally can only be maintained at around 1.2, it is difficult to more than 1.3.3. because of the difference between chemical composition and acidity coefficient of rock wool and slag cotton, they also show some differences in performance.(1) the difference of water resistance(2) difference of heat resistance;(3) difference in corrosion resistances
What are the requirements for floor and exterior wall waterproofing in building construction?
- Building exterior wall waterproof design should include the structure through windows and doors, awning, balcony, cracks, out wall casing, capping, embedded parts, prefabricated wall parapet and the intersection area of waterproofing. 5.1.3 the waterproof layer of the exterior wall shall be installed on the surface of the water.s
