(Rock wool has been identified IARC authority to not carcinogen) application: Rock wool board is widely used in petrochemical, textile and metallurgy, electric power transportation, construction and agriculture. In recent years, the building exterior insulation fire due to improper material selection often occur to people's lives and property caused great losses, applied for building up wool characteristics developed a series of products: 1, exterior insulation Rock wool board is designed for the construction of exterior insulation system design and production, suitable for concrete or brick and other dense structures new or existing buildings external wall insulation or energy saving. It has the highest fire rating class A1 in fire insulation, acoustic noise reduction, while also having a high compressive strength and anti-pull strength, low water absorption and moisture absorption, good dimensional stability, resistance to aging, etc., can better compatible with the external walls of the system, and building structure basically the same life of the building to provide effective thermal insulation, fire and extreme weather protection and other properties. 2, roof special wool board is designed for all types of flexible waterproof roof system design and development of set thermal insulation, fire protection, acoustic noise and other functions as one of rock wool products, has good compressive strength and resistance to pitting load capacity, Good water-repellent, moisture resistant, short-term and long-term wet and low water absorption, resistance to aging and weathering resistance, good physical and chemical stability. Weight bearing and related equipment needed to meet the roofing system installation and maintenance. 3, curtain wall with rock wool board is designed for curtain wall system design with higher refractory temperatures, higher melting point and smaller linear shrinkage temperature and other characteristics, but also has good water-repellent, moisture resistance, low moisture absorption and water absorption, not metal will have a corrosive effect. 4, Fire Barrier Barrier rock wool developed for use Production, which uses thick wool board cut into strips, the use of the fibers perpendicular to the wall, providing a great rock wool anti-pull strength, mainly used reach the A1 level of external insulation materials supporting the use of EPS, XPS and other combustion performance, increase the fire performance of building exterior insulation system and security. Fire performance: color composite sandwich panels and insulation materials surface material is non-combustible material, fully able to meet fire code requirements. Durability: Various studies show that more than 40 years and is widely used abroad confirmed, with a special coating color steel shelf life of 10--15 years, every 10 years after spraying anti-corrosion coatings, lumber life of up to 35 years. Appearance: pressure plate clear lines of up to dozens of kinds of colors, can meet the needs of any style buildings, to achieve satisfactory results. High intensity: the use of high strength steel for the substrate (of tensile strength 5600KG / CM) coupled with the most advanced design and roll forming, with excellent structural properties. Insulation: The composite board insulation materials used are: wool, fiberglass, polyethylene, polyurethane, etc., low thermal conductivity, good insulation effect. Systems approach 1, Exterior: special adhesive mortar should be used with the base wall bonding, supplemented by bolt and mesh. Finishes for a variety of hanging wall and directly paint finishes wool board 13,084,554,488 need to be cautious and not for brick veneer. 2, roof: low intensity, high water absorption, can not be used for roofing. 3. The implementation of the standards: National and Jiangsu Province have not yet introduced the applicable standards. Architecture structural action wool board is mainly composed of: adhesive layer, insulating layer, wipe the surface layer, decorative layer and accessories. Attributed to the adhesive layer for the construction, between the bottom and the surface layer is between the primary gelling material firmly bonded to the upper and lower layers, their main source of inorganic filler. Insulation in order to avoid and reduce heat loss to the environment turbines, steam turbines and insulation material layer pipe laying substandard appearance, the main filler as rock wool fibers and a certain amount of organic matter and water, as well as adhesives. Facing layer should be used plasters, mortars and other light embellishment functional coating or outstanding breathability aqueous exterior paint, so let wool board maintains its lightweight characteristics, also increased its aesthetics. Selection of the main types of paint accessories, while increasing the surface of the color of rock wool board, so that it could be applied to any environment as well as fire-retardant coating and thermal insulation can play a role to some extent. 2 cracks because of stress at door and window openings gather, causing the protective layer and the facing layer exhibits flaws. 3, the protective layer and the facing layer shrinkage is large, leading to produce vitality flaws; insulation material insulation materials on the market, can the apparent density, temperature, compressive strength, thermal conductivity, water absorption and other properties to meet the requirements and use in energy-saving building insulation materials are: polystyrene foam board (EPS and XPS), rock wool board, glass wool blankets and lightweight Polystyrene insulation materials such as pulp. All of the above materials have a common characteristic is within the material has a lot of closed pores, and their apparent density are small, which is also used as thermal insulation materials are essential. Cautions 1. To pay attention to rain, not construction in the rain. 2. For cold is bound to the vapor barrier, in particular at low temperature conditions, with resin-free wool to insulate, the vapor barrier must also be fireproof 3. When the temperature exceeds a certain temperature, for example: 200 When ℃, heat must be added a suitable external protection, so as not to make wool board thickness and density to change. The large diameter peace related equipment wool finished wall insulation, beyond 200 ℃, must remember wool board manufacturer told: add insulation nails, (pitch around 400mm) outer jacket to snapping. 5. The required insulation equipment, insulation nails and pipes for the benefit of antiseptic, can receive proper coating. Additionally there should be no place leaked. So it can achieve better results. 6. In the case of rock wool board finished outdoor insulation should be subject to mechanical wear is appropriate metal or plastic wrap, then place attention joints, seams sealed, plus gum seal if necessary, wrap a layer stack locally not less than 100mm 7. When holding an object placed at 90 degrees, and there is a certain height, rock wool insulation board is bound to have locating pins or support ring, spacing must not be greater than 3 meters, insulation materials to prevent sliding down when there is shock . 8. In order to be able to achieve the minimum heat loss off target, rock wool board and felt the butt joints must be tight, if there is a multi-layer insulation various cross seams need interwoven open, so as not to constitute a thermal bridge, when the cold must eradicate cold bridges . Industry access standards will be strictly insulation develop China Energy Conservation Association pointed out that, according to preliminary estimates, the five-second period, the national average annual completion of the new building area of ??20 million square meters, according to the most conservative demand estimates, the annual demand of rockwool 238 tons, the output value of 11.9 billion yuan to create. Predictably, in the face of a huge market space, various capital investment wool production line will become a market choice. The production line in order to avoid duplication, the Ministry has drafted a timely exterior insulation Rock wool industry access conditions. Access conditions to determine the production line construction conditions, layout, scale and process equipment, product quality, energy consumption, environmental protection, health and safety and social responsibility and many other indicators. Among them, the scale index for an initial annual capacity of 20,000 tons. Experts point out that, although the number of existing SMEs can also increase investment to increase production capacity, but at multiple standards layout, equipment, energy, etc., can meet the enterprise is not too much, a huge gap in the market mainly by leading enterprises to fill. Ministry sources said that through the establishment of high barriers to entry, will support the advanced productivity speed up the layout, adjust and optimize the product structure, to encourage bigger and stronger to do good, and guide the healthy and sustainable development of industry. Rockwool mineral wool market demand this year, that is, a exterior insulation material. In recent years, when the market share amounted to 90% of the organic insulation material at a standstill waiting to see, as to fire Grade A inorganic material exterior insulation wool has ushered in an unprecedented market opportunity. This year around, wool prices by 42 yuan / square meter rose to 200 yuan / square meter. Even so, the market demand is still in short supply. The reason why wool material price increases, policy adjustment is the direct cause. As in recent years, Beijing, Shanghai, Shenyang, and other places the fire, so fire drawbacks of the current large-scale use of exterior insulation and organic material exposed. In March, the Ministry of Public Security Fire Bureau issued "to further clarify the civil construction supervision and management of fire insulation materials relevant requirements of the notice", the civil construction insulation materials incorporated into fire safety design, fire inspection and record the scope of checks, and provision of civilian building insulation materials must meet the A grade. 13084554488
