First, the advantages of polyurethane exterior wall spraying 1. Strong stability The solid combination of rigid foam polyurethane spraying and the base wall is the basic premise to ensure the stability of the external thermal insulation layer. For the wall, the surface should be treated with interface treatment. If the surface layer is loose and hollow, it needs to be carefully cleaned to ensure the hard The foam polyurethane spray insulation layer is closely combined with the wall. The rigid foam polyurethane spray external insulation system should be able to resist the combined effect of the following factors, that is, under the unfavorable local temperature and humidity conditions, it can withstand various internal and external factors such as wind, self-weight and normal collision. Combined load, the insulation layer still does not separate from the base, fall off and remain stable in the wet state. 2. Good thermal insulation performance Rigid foam polyurethane exterior wall spraying is a high-grade thermosetting polymer, which is an excellent thermal insulation material. Due to the high bonding strength between rigid foam polyurethane exterior wall spraying and general wall materials, it does not require any adhesives and anchors. It is a natural adhesive material that can form a continuous thermal insulation layer, which ensures the joint action of thermal insulation materials and walls and effectively blocks thermal bridges. 3. Good fire performance Although the rigid foam polyurethane spray insulation layer is on the outside of the outer wall, the fire prevention treatment can not be ignored. After adding the flame retardant, the polyurethane is a flame-retardant and self-extinguishing material. A fire protection system can effectively prevent the spread of fire. The wall surfaces, doors and windows and other sides of the building are all tightly covered with fireproof rubber powder polystyrene particles, and there must be no exposed parts. Thick rubber powder polystyrene particles are used to waterproof and wipe The gray surface layer is beneficial to improve the fire resistance of the thermal insulation layer.

2. Technical performance requirements of polyurethane exterior wall spraying 1. Wind pressure resistance value: not less than the engineering wind load design value, and the safety factor K should not be less than 1.5. 2. Water absorption: soak in water for 1 hour, the water absorption of the system with only plastering layer and complete protective layer should not be greater than or equal to 1.0. 3. Impact strength: Walls, doors and windows and other vulnerable parts on the first floor of the building: 10J level; the walls above the second floor of the building are not easy to collide. 4. Freeze-thaw resistance: After 30 anti-freeze-thaw cycles, the protective layer has no cavitation, falling off, no leakage cracks, and the tensile bond strength between the protective layer and the insulation layer should not be less than 0.1mpa, and the damage Parts should be inside the insulation. 5. Weather resistance of the system: After the polyurethane exterior wall spray insulation system has passed the weather resistance test, the surface layer will not foam or peel off, the protective layer must not be hollow or peeled off, and leakage cracks must not be generated. The tensile bonding strength of the plastering layer and the insulating layer It should not be less than 0.1mpa, and the damage should be in the insulating layer.

1. How to choose to buy polyurethane insulation pipe? 1. The surface test of polyurethane insulation pipe includes observing the surface gloss, finish and thickness. For example, you can see the surface gloss to understand the advantages and disadvantages of the material, and you can also touch the surface by hand to observe the gloss. 2. Material inspection is a kind of solidity inspection. The hardness of the polyurethane insulation pipe is related to the quality and thickness of the material. The visual test is not obvious, and you need to test it yourself. 3. Price comparison, find several entities for price comparison, if some manufacturers offer very low prices, you should pay attention to the quality of polyurethane insulation pipes, and the cost is high. Of course, the price will be very high, and vice versa. . 4. From the perspective of service, high-quality service is the protection of traditional polyurethane insulation pipes. In addition to product quality and cost-effectiveness, which are several important factors that buyers should consider, there is also a service about production, especially after-sales Service to see if one-to-one measurement, installation service is provided, and whether there is a quality certificate, which is the guarantee of purchasing qualified polyurethane insulation pipe.

First, the advantages of polyurethane insulation pipe 1. The thermal insulation performance of the ester insulation pipe is very good, and the heat loss caused by it is smaller than that of the traditional pipe, which is about 25% of the traditional pipe. Therefore, the long-term use of the energy-saving pipe can save a lot of energy. 2. Polyurethane insulation pipe is easy to construct, has relatively low comprehensive cost, and has strong corrosion resistance and impact resistance. 3. Polyurethane insulation pipe has a long service life. 4. The installation cost is low, which can save a lot of installation costs

1. Installation of polyurethane cold storage board 1. The installation of the polyurethane cold storage panel wall panel should be carried out in strict accordance with the installation specifications and layout diagram. During installation, the polyurethane cold storage panel wall panel should be properly cut at the processing site, and the surface film about 5cm on both sides of the concave-convex groove of the cold storage panel should be torn off. , Perform continuous sealant treatment on the inside of the groove. 2. Hoist the polyurethane cold storage board to the designated position and fix it with nylon bolts and the steel purlins on the periphery of the wall. When fixing the wall panel, start from the corner of the outer wall, and install the wall panel to both sides with the base board as the base point, and each cold storage board is fixed. 6 nylon bolts, when inserted into the next board, squeeze with the first board, and the convex grooves are tight. The board seam is controlled at 5mm±1mm, which is used for the expansion and contraction of the polyurethane cold storage board at low temperature. 3. When the first polyurethane cold storage board is fixed in place, pull a continuous alignment line vertically, this line and the first cold storage board will become the guide line, which is convenient for the quick installation and correction of the polyurethane cold storage board, and then adjust the During installation, each wall area should be inspected in certain sections. The method is to measure the length of the fixed cold storage board, and measure it once at the top and bottom to ensure that there is no movement and fan-shaped. The intersecting parts of the polyurethane cold storage board are treated with tearing film and glue. The tearing film should be clean, and there should be no residual points.

First, polyurethane changes the type and composition of raw materials. It can greatly change the product form and its properties, and obtain the final product from soft to hard. Because the form of polyurethane products includes soft, semi-rigid and rigid foams, elastomers (polyurethane elastomers mainly include thermoplastic TPU and thermosetting ―It is mostly realized by casting process (CPU), paint coatings, adhesives, sealants, synthetic leather coating resins, elastic fibers, etc., so it is widely used in automobile manufacturing, civil engineering, footwear, synthetic leather, aviation, medical treatment, agriculture, etc. Many areas. 1. It is an indispensable material to seal and fix wood, plastic steel, aluminum alloy and other metal door and window frames. 2. Wrap and seal cables and wire boxes, air-conditioning pipes, thermal insulation hot and cold water pipes. 3. Filling voids in masonry buildings; the voids in the hull are often a headache, but it can be used to fill in very well. 4. Home maintenance: fill holes and gaps, and holes in floor tiles and floors can also be repaired using it. 5. Landscape gardening: very suitable for flower arrangement, garden engineering decoration. 6. Advertising exhibition: Because of its unique plasticity, it is beneficial to model making, sand table manufacturing, and display panel repair. 7. Packaging and transportation: You can immediately wrap up some valuable and fragile items to avoid the danger of being broken. 8. Refrigerated air conditioner: The caulking, sealing and heat preservation around the refrigerator and air conditioner make the service life of the air conditioner longer.
