  • Detail

In recent years, thermal insulation coatings have been widely used in life. Thermal insulation coatings can generally be divided into hydrophobic silicic acid thermal insulation coatings and rubber powder polystyrene particle external wall thermal insulation coatings. The former is composed of various high-quality thermal insulation materials such as high-quality foam stone wool, aluminum silicate fiber, expanded perlite, organic silicon and high molecular polymers. It has excellent thermal insulation performance and is widely used for thermal insulation of walls, tanks, cold storage, pipelines and so on

thermal insulation coating has extremely strong weather resistance, low thermal conductivity and stable thermal insulation performance. After long-term technical improvement, the thermal insulation coating can withstand the high temperature of 1800 degrees, and the inhibition effect of thermal insulation can reach about 90%. At the same time, the thermal insulation coating also adopts the flexible anti crack technology, which can disperse and eliminate the damage of external adverse factors at any time, and effectively prevent the cracks on the wall. Then, the following editor will introduce the acceptance of thermal insulation coating and the construction technology of thermal insulation coating

acceptance of thermal insulation coating

first of all, for the acceptance of thermal insulation coating, we should carefully check whether there are defects in our operation after the implementation of thermal insulation operation, including whether there are traces of repair of scaffold fixing points, whether the sealing points are in place, whether the wall is flat, and whether the color conforms to the overall feeling

1. The base course shall be treated in the acceptance of thermal insulation coating to see whether it meets the requirements of design and construction technology

2. Used slurry. Check the quality of building walls with block materials, plates and other wall insulation materials to see whether they are suitable for the requirements. It is necessary to comprehensively consider the material density, compressive strength, thermal conductivity of the thermal insulation board, the softening coefficient, setting time, thermal conductivity and compressive strength of the thermal insulation slurry, and the bonding strength of the bonding material

3. Whether there is an irregular effect during the operation of the main structure and the quality of the base course, whether the waterproof layer has a comprehensive protective surface, and whether the base course has reached the crack resistance characteristics

construction process of thermal insulation coating

1. Snap the control line: according to the building facade design and the technical requirements of external thermal insulation of external walls, snap the horizontal and vertical control lines, expansion lines, decorative seams, etc. of external doors and windows on the wall

2. Hanging datum line: Hang vertical datum steel lines at the big corners (internal and external corners) of the external wall of the building and other necessary places, and hang horizontal lines at appropriate positions on each floor to control the verticality and flatness of the polystyrene board

3. Prepare special adhesive: prepare it according to the mixing proportion provided in the operation manual of the special adhesive, which shall be in the charge of a specially assigned person, measured strictly, and stirred mechanically to ensure uniform mixing. The mixed adhesive can be used only after it has been stopped for 5 minutes. The adhesive must be used as soon as it is mixed, and the mixed adhesive should be used up within 1h. Pre stick and turn over the mesh cloth: all exposed places on the side of the polystyrene board (such as expansion joints and door and window openings) should be turned over with the mesh cloth

characteristics of thermal insulation coating

1. It has excellent weather resistance. Low thermal conductivity, stable thermal insulation performance, high softening coefficient, freeze-thaw resistance and aging resistance

2. Soft anti cracking technology is adopted. The change index of elastic modulus of each layer of material is matched and gradually changed layer by layer, which allows the combination of deformation and limited deformation, and can disperse and dissolve the deformation stress at any time. The base course has strong adaptability to deformation and effectively prevents the occurrence of wall cracks

3. The system has no cavity and strong ability to resist negative wind pressure. It is suitable for multi-storey and high-rise buildings

4. It has good permeability and strong respiratory function, which not only has good waterproof function, but also can remove the moisture of the insulation layer

5. The fire resistance rating is grade B1

6. The construction is convenient, and the problem of inaccurate weighing on the construction site can be avoided by using the pre mixed dry mixing and light aggregate sub loading technology. It can carry out multi-point and multi-level construction with high speed

7. Strong correction ability. It has good adaptability to the construction of structures with low flatness, and can effectively correct local deviations

8. The comprehensive cost is low

editor's summary: that's all for the acceptance of thermal insulation coating and the construction process of thermal insulation coating. I hope it will be helpful to you. If you want to know more, you can pay attention to information
