And after construction, the construction should take effective measures to prevent water erosion and sun exposure, and should be done in a protective layer. The job suddenly encountered rain, we should take measures to prevent the rain washed walls; freezing winter construction should take measures in accordance with the relevant standards. 7. Before the large-scale construction, required to be on site using the same materials, construction practices and processes production model the wall, and after confirmation the parties concerned before proceeding construction. 8. construction of rock wool board, operations workers should wear PPE good, good occupational health protection and focus on construction safety. 9. The material will be seized related to rock wool insulation system board should be sent to a qualified testing bodies, testing qualified before use. 10. wool board should adopt the strip sticky paste method or point bonding method, coating an area of ??not less than 50%. After the wool board finished wiping adhesives, insulation board should first stick the lower end of the grass-roots, bottom-up rock wool board should be laid horizontally along the horizontal direction, and should take the side edge anchoring shop, slab should naturally try to be, the gap between the plates no larger than 2mm, such as when the slit width 2mm, should be filled with insulation material handling, adjacent board should be flush with the height difference between the board shall not exceed 1.5mm. 11. All up wool board and member of the pipeline wall, the outlet portion of the application of the same material after sealing processing infill. 12. If found veil off, should take timely adhesive or fixing anchor anchoring manner and timely outer finish layer construction in the construction process. 13. wipe the surface layer construction should meet the following requirements: 13.1 wool board pasted finished plaster panel to deal with surface treatment, the entire surface of a stainless steel spatula scraping mortar coating (thickness 1 ~ 1.5mm), and pressed into the surface layer of rock wool fiber board. 13.2. Plastering mortar should be strictly configured in accordance with product instructions, configured adhesives should avoid direct sunlight, and should be used within 2h. 13.3 wipe the surface layer Layer 2 points. The first layer of plaster mortar thickness 2 ~ 3mm, you should use stainless steel serrated spatula plaster, with a large spatula after disappearing, and while wet pressed into fiberglass mesh, to be a little glue to dry and hard to touch when available install anchors, wipe the surface with a plastic disc anchor closure mortar in and around; a first layer of plaster mortar may be a second layer of slightly dry plaster mortar construction, the thickness of about 2mm, erase and wipe the surface layer thickness design requirements. 13.4 Laying mesh should be smooth, looking straight, and keep the yin and yang of the Founder and the vertical angle of the upper and lower mesh, should have about overlap between its lap width of not less than 100mm; fiberglass mesh must not be laid directly in wool board surface, it shall be exposed, can not dry lap. 13.5. Installation design requirements should be the position of the anchor, with the impact of drilling or hammer drilling, drilling depth should be larger than the anchoring depth 10mm, anchor nails or screwing knock when installing walls, close to the first disc layer mesh, and promptly covered with plaster mortar and its surrounding disk. 4 Note Editor 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 . 5 industry standard editing 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 2.38 million tons of rock wool, can create value 11.9 billion yuan . 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 in 2014, that is, a exterior insulation material. When the city [1]? Field occupies amounted to 90% of an organic insulating material is at a standstill waiting to see, as to fire Grade A inorganic material exterior insulation wool has ushered in an unprecedented market opportunity. Wool prices by about 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. 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 provides civil construction insulation materials We must reach A-level.
