How to effectively insulate summer living on the top floor? Look at the experience summed up after the renovation

With the advent of midsummer, friends who have lived on the top floor should all feel the distress that the walls are still hot at night in summer. Some experienced owners will do a good job of heat insulation when decorating, which not only reduces the worries of hot summer homes, but also saves a lot of electricity bills in the later period. Therefore, it is very important to heat insulation and cool down the penthouse building in summer! Today, Xiao Bian will share how to make heat insulation measures on the top floor ~

Application of alumina fiber

As one of the seven strategic emerging industries in China and one of the ten key areas of "made in China 2025" and the key areas in the 13th five-year National Science and Technology Innovation Plan, the new material industry is the industrial foundation for the transformation and upgrading of the whole manufacturing industry. The core manufacturing technology of alumina fiber needling blanket has been tightly blocked by developed countries due to its outstanding product advantages, while China has long relied on imports for this product. A very large application market for alumina fiber needled blankets is the three-way catalytic converter sealing gasket in exhaust gas treatment equipment in the high-end automobile industry. At present, the sealing gasket in the automobile industry is made up of Mitsubishi of Japan, IBIDEN of Japan, and 3 of the United States.

Matters needing attention after the construction of inorganic fiber spraying

Before spraying, various pipelines, air ducts and other equipment hangers shall be installed to avoid drilling and chiseling on the base surface after spraying. During the drying and curing of the finished product, avoid mechanical impact and rain erosion. When the spray coating is damaged due to collision, it should be repaired locally. For the parts that are often vulnerable to mechanical collision, glass fiber cloth or other protective materials can be pasted to protect the surface of the fiber layer. Keep the environment of the spraying area clean to avoid dust flying and contaminating the surface of the finished spray coating. In the process of spraying construction, spraying operators should follow the relevant provisions of the national labor protection regulations,

Operation Points of Inorganic Fiber Spraying Insulation Project

1, raw material appearance quality inspection before construction, should be sprayed fiber cotton and adhesive sampling inspection, fiber cotton should be dry without caking, white without dirt, adhesive should be no stratification, no foaming, no deterioration and discoloration; 2. Spraying base surface treatment (1) and spraying base surface treatment: clean up dust and dirt on the spraying base surface with compressed air or clear water; Check whether the hanging parts and embedded parts are firm, and tighten the loose parts, if the original base surface has been damaged or there are serious cracks, should be repaired first. (2), the doors and windows and various equipment, pipelines and non-spraying parts of the protective block, blocking fee spraying parts and ventilation pipeline through hole. (3) Clean up the obstacles on the working surface, ensure the smooth movement space and safety of the spraying hand, and maintain the best spraying distance and spraying angle. 3. Material preparation and debugging (1), break up the compressed fiber cotton, continuously fill the sprayed cotton into the spraying machine, and keep the fiber material in the material box sufficient. (2) A special person shall be responsible for diluting the adhesive stock solution with clean water in a professional matching container (a 200-liter graduated plastic container equipped with a high-speed stirrer) according to the instructions for spraying the adhesive. The preparation ratio shall be strictly controlled, and the water dilution shall not be increased at will. The electric stirrer shall be continuously started for uniform stirring. The stirring time shall not be less than 5 minutes. Each barrel shall be prepared one by one, and prepared as required to avoid freezing and failure. 4. Pre-spraying primer on the surface of the base layer: after the surface of the base layer is cleaned, the prepared spraying adhesive can be used to pre-spray glue on the base surface, and the glue amount is appropriate and uniform without flowing.
