Heat insulation coating construction technology of


a, foundation treatment, foundation treatment is the first step, processing the goal is to keep the metope rough, dry but basic level off, the strength and stiffness must also be up to standard. Next, after the processing of the surface of the base coating interface agent, and wipe the heat preservation mortar, make efforts to protect horn.


2, polishing putty leveling: metope is water wet, with metope of sand paper burnish, flexible putty scraper scrape twice, make metope level off is smooth.


3, grassroots back cover: clean up the dust on the surface of the spraying, paint, with excellent short hair roller roller, the construction process carefully.


4. Paint construction: finish the construction on the environment conditions of the demand is higher, the temperature should be higher than 5 degrees, is free from the influence of the bad weather such as wind and rain, to ensure the smooth progress of construction paint and standard quality.


5. Spray paint and modelling: according to the design requirements of the user or manufacturer, have good area, then spray coating, spraying attention to ensure uniform thickness.


6, exterior wall coating elastic paint twice: pop-up color line, and then from top to bottom in matte painting, after the first shallow depth.


7. Cleaning: look carefully metope after construction, pay attention to whether metope of spray paint color uniform, color separation line is straight, presence of sagging or Dally, if any, in a timely manner to correct.


the characteristics of thermal insulation coatings


1) Heat insulation coatings are usually excellent weathering resistance, low thermal conductivity, insulating stable stays, freezing-thawing resisting sexual, and aging resistance.


2) The material using the flexible and crack technology, each layer of material change of elastic modulus index matching and the gradient step by step, may at any time dispersion and eliminate deformation stress. Grassroots deformation and strong adaptability, can effectively resist the cracks of the wall.


3) No cavity system, negative wind pressure resistance is strong, suitable for multi-storey and high-rise buildings.


4) Good ventilation, respiratory function is strong, good resistance to water, not only can eliminate the moisture inside the insulation layer.


5) Heat insulation coating fireproof rank for B1.


6) Construction is convenient, the use of ready-mixed dry blend lightweight aggregate packing technology, can avoid the construction site to weigh the problem of inaccurate. Can be more multi-level building at a high speed.


7) Error correction ability. Good adaptability and effectiveness of low roughness structure construction


to decorate, correct local deviation.


8) Heat insulation coating of comprehensive cost is low, so the price is relatively cheap.
