FAQ:

Insulated Flexible Ductings Biggest Manufacturer in China

Q: Air conditioning ventilation when the sound is a big reason: Buried plastic pipe under external load, the diameter of the vertical diameter deformation rate should be less than the allowable diameter of the pipe deformation rate The diameter of the allowable diameter of the pipe shall not be greater than 5% The diameter deformation rate of the pipe and the allowable diameter deformation rate are calculated as follows: ε ΔD / D0 × 100% [ε] ε0 / K where: εΔD pipe in the combined load (Mm) [ε] Permissible diameter Deformation rate ε0 Elastic diameter Deformation rate (%) of pipe, by the flattening of the diameter of the pipe diameter (mm) The test determines the K safety factor, generally desirable 15

Q: US direct mail dysonhp01 Dyson air purification cooling machine triple in the country to warranty it: Among them, the extruded polystyrene gypsum composite board is based on paper gypsum substrate, the use of adhesive and extruded polystyrene board through the factory processing compound

Q: Do 3cm thick wall insulation how much kilogram of slurry and how many kilograms of polystyrene particles: From the outside: ① rigid waterproof casing is only composed of steel casing and wing ring, simple structure; ② flexible waterproof casing mainly by: flange casing, seals, flange pressure plate, wing ring, bolts, nuts Composition, complex structure From the waterproof performance up to choose: ① rigid waterproof casing is outside the wing (ring made of steel ring on the steel pipe), installed in the wall (mostly concrete wall), for the general pipe wall, ; ② flexible waterproof casing in addition to the external wing ring, the internal file ring and the like, the flange wire, there are sets of sales, but also their own processing, for the need for shock absorption pipeline, such as and pump connected When the pipe is through the wall In other words, if the wall on both sides of the waterproof performance, it is necessary to use flexible waterproof casing; if only to consider the pipe through the wall, without considering the wall, the wall on both sides of the waterproof performance and displacement of the pipeline deformation You can use rigid waterproof casing

Q: I added the space 18 degrees opened for 5 hours or not cold, we all know how is it? More: Common points are all sandwich panels, with a hard protective layer, the difference is the middle of the different materials, such as polystyrene board, polyurethane board. Polystyrene board which is the most common, because the price is cheap, easy to use so the use of more, but if the temperature is more than the requirements of the chicken inertia glycosylation moxibustion slim faint words, polystyrene board is not satisfied , So there is a polyurethane sandwich panels, polyurethane thermal conductivity of less than 0.. in the existing insulation materials, large quantities of processing, be the best. But because of its process is more complex, and the cost is relatively high, so with less, the common combination of cold storage and the like, I believe that with the economic and technological development, polyurethane sandwich board market share will be more and more High

Q: Air conditioning machine work when the sound is too much reason: Color steel plate, refers to the color coated steel plate, color coated steel plate is a kind of organic coating with steel plate

Q: What is the whole heat exchange fresh air ventilator?: (GJG130 - Fan Jutang Duanjie Daojie Juejiao 2001) will be replaced by (GJG130-2011) is expected to begin the implementation of the construction of this year, the construction of fastener steel scaffolding safety technical specifications (GJG130), the construction of fastening steel pipe scaffolding safety technical specifications (GJG130- -2011)

Q: External wall insulation method of operation There are several combinations of materials: 30-150 per square meter has, mainly to see the material, thickness and so on

Q: The installation method of ordinary air conditioner. The more detailed the better. Please thank you all: 2.1.23 step distance liftheight the distance between the upper and lower horizontal axis of the axis of each other. 2.1.24 pole vertical (cross) distance longitudinal spacingofuprighttube Scaffolding vertical distance between adjacent rods. 2.1.25 Vertical distance transversespacingofuprighttube Scaffolding Horizontal distance between adjacent vertical rods, single row scaffolding for the outside pole axis to the wall distance.

Q: Ventilation is very good, why still have to install fresh air system: Also known as foam board, EPS board, is containing volatile liquid blowing agent of the polystyrene beads can be preheated by heating, heated in the mold and the formation of white objects

Q: In the design, the building structure and the hydropower are generally designed by the Architectural Design Institute. The air conditioning ventilation is based on the design of the room. Or first air conditioning ventilation? More: Decoration refers to the home improvement part, housing construction is the content of the building
