- Q:Can the kitchen sewage pipe pass through the walls of the stove wall?
- English: expandedpolystyreneboard molded polystyrene foam board - also known as foam board, EPS board, expandable polystyrene foam board, etc
- Q:Find a joint electronic M1.5.4 type ECU application system wiring harness and layout Thank you, anxious! The
- According to the intrinsic composition of insulation materials can be divided into: inorganic insulation materials and organic insulation materials! Fire rating A is a non-burning point with the insulation effect of materials, materials. Class A non-combustible materials have the characteristics of low density, low thermal conductivity, high pressure capacity, convenient construction, economical and durable. They are widely used in thermal insulation materials and industrial industries such as hot pipes, thermal equipment and other industrial piping equipment and industrial buildings And the civil building envelope structure of the insulation, insulation, sound absorption materials. Because of its good thermal stability, and more for the steel structure of the fire protection coating material. Fire rating B1 level is a flame retardant insulation material, is determined according to the fire resistance of the material, in addition, different parts of the material division is also different! Burning performance: refers to the material and / or products in case of fire burning all the physical and / or chemical changes, that is, the fire reaction characteristics. Fire rating B2 is a combustible insulation material also known as flame retardant materials, mostly organic insulation materials, add the right amount of flame retardants. More common for EPS expansion polystyrene board and XPS extruded polystyrene board, that is, we often say that general board. This material is low in ignition and releases a lot of harmful gases during the combustion process. Fire rating B3 is a flammable insulation material, this is more common as the main material of polystyrene foam insulation material, because this material is easy to burn,
- Q:What materials are made of flexible pipes? Why should the mechanical ventilation set the flexible tube? Where should I be located?
- It is recommended to use the home of the heart of the card to worry about toughness to fill the joints, and then paste the seam (master understand) if directly in the sandwich panel (plate) on the batch of putty powder or spray painted really easy to drop off the phenomenon of stone, the first primer, it is recommended to use the home of the German brand brackish scraping scraping again There are), to be dry and then approved scraping putty powder spray really stone paint
- Q:CAD type too much (including civil engineering, interior spring design, motor, machinery manufacturing and many other), a beginner how to choose?
- Extrusion plate (XPS) is a polystyrene resin or its copolymer as the main component, add a small amount of additives, made by heating and extrusion with a closed-cell structure of the rigid foam
- Q:How to optimize the construction management to improve the quality of construction projects
- flexible waterproof casing for seismic fortification of the region, rigid waterproof casing for the pipeline to touch the tattoo Du Gu Sen single point of the wall does not bear the vibration of the building
- Q:Drain flexible pipe to keep the base design above the elevation of the number of meters
- Flexible pipe with metal materials, such as metal mesh, organ, etc
- Q:To ask why the use of clamps connected to the spray pipe after the flush again after the water there will be a lot of hook link position leakage phenomenon? Thank you! The The
- The radial force of the seal is far greater than the axial force of the connecting bolts but all the axial force washers 窢 field urging 讵 peculiar aldehyde support, good self-sealing effect by the pipeline through the media rubber ring pressing force pressure more sealing performance of the more pressure to prevent the pressure of the rubber ring to the inner diameter of the tube end of the interface diameter Preload to prevent the media pressure leakage and the blue compared to the higher the pressure of the pipe the more the advantages of the more dangerous the pipe junction at the flexible state of the clamp and the tube between the gap between the clamp clamp a small number of adjacent pipe to allow the corner tube Pipe pipe between the end of the gap to allow the axial shift of the pipeline to adapt to the expansion and contraction of the pipe; pipe interlocking effect reduced 70% mechanical vibration
- Q:What is the difference between a rigid pipe and a flexible pipe, what kind of pipe is rigid, what is flexible
- Tower crane is used to lift objects up and down the lifting of the object is not clear the length of the arm of the tower crane!
- Q:What are the scope of construction work special operators?
- For air conditioning manufacturers, in order to standardize the product design, the two products may be the host of the heat exchanger, compressor, fan motor selection for the same, but they will specifically for different types of product design, manufacturing different main Control parts, and the two models of the host model is completely different.
- Q:The sound of water pipes will not produce infrasound damage to the human body?
- The first look at the factory declaration materials in the building level. The second depends on the material you use sandwich panels. (Generally Caigang sandwich rock wool no problem, glass wool depends on the design requirements of the building).
