How to maintain the fireproof and thermal insulation of the construction site?

The construction site fireproof and thermal insulation is replaced by the traditional thermal insulation. It can be used for about 5-9 years, and the heat insulation is easy to use. Under the same conditions, the temperature can be increased by 10 degrees compared with that of grass, which is convenient for storing personal collections. This product is suitable for solar greenhouses, smart greenhouses, ecological garden restaurants, and short-distance transport vehicles. , vegetable greenhouses and other thermal insulation covers are good substitutes for grass and mountain stone quilts. The fireproof and thermal insulation of the construction site has a small heat transfer coefficient and good thermal insulation properties, especially when the temperature difference changes greatly; low moisture content, good waterproof properties; excellent tensile and compressive properties; easy to use, engineering Simple construction, suitable size; odorless and clean. Note: Although the above-mentioned types of thermal insulation quilts often have good thermal insulation properties, they are all suitable for mechanical equipment rolling, and the total area of ​​marketing promotion and application is constantly developing. However, because they still have different shortcomings, they still need to be continuously improved to make them more ideal and easy to use. The fireproof and thermal insulation quilt on the construction site should also have the characteristics of thermal insulation, light transmittance, waterproofness, relaxation degree, and long service life. The rapid development trend of agriculture is the fire protection and thermal insulation of construction sites, and the thermal insulation of greenhouses is also gradually accepted by agricultural planting, project construction sites, and bridge ground insulation. Fireproof and thermal insulation of the construction site is used for winter construction"cotton clothes", Improve the quality of the project! The raw materials of traditional fireproof and thermal insulation quilts for construction sites include straw, pouf, paper quilt and silk quilt, thermal insulation felt, etc. It also reduces the thermal insulation properties, and causes serious environmental pollution to the plastic film, so it is very easy to reduce its light transmittance. The new thermal insulation felt (quilt) developed and designed at this stage needs progress in getting rid of the shortcomings. An ideal fireproof and thermal insulation quilt should have the advantages of low thermal conductivity, strong thermal insulation, moderate net weight, easy to roll, strong wind resistance, moisture resistance, long service life, etc. How to maintain the fireproof and thermal insulation of the construction site? 1. If the cold-proof, frost-proof and thermal insulation is wetted by rain, it should be exposed to the sun for a period of time before being rolled up the next day, and then rolled up after it is basically dry. 2. When installing the cold-proof and anti-freeze insulation quilt, the stubble between the two beds of the cold-proof and anti-freeze insulation quilt should not be less than 10cm. 3. After the cold-proof and anti-freeze insulation quilt is covered, a waterproof film should be covered on it. Roll up again. 4. When the thermal insulation quilt is not in use, choose to dry it on a sunny day and store it in the house, and then transport it home and seal it with a greenhouse. It is strictly forbidden to be exposed to the sun and rain. 5. The anti-cold and anti-freeze insulation quilt should be handled with care during transportation to avoid tearing, puncturing and abrasion. The use method of the fireproof and thermal insulation quilt on the construction site is very simple and plays a relatively large role. Due to the strong rainproof and waterproof performance of the tarpaulin and its strong performance, the surface of the thermal insulation quilt used for engineering can also play the role of rainproof and waterproof on the basis of thermal insulation. The role of anti-corrosion and fire prevention (fire-proof tarpaulin is required for fire prevention). It can also play a role in stabilizing fire protection while insulating the engineering building. Therefore, the tarpaulin thermal insulation quilt is a special thermal insulation quilt for the thermal insulation of concrete construction projects. These are some of the help we have seen in using engineering insulation quilts, which can give us many advantages in practical applications. Therefore, engineering thermal insulation quilt has also become a thermal insulation equipment that many people need. When using materials such as aluminum foil film, aluminized film or mixed aluminum film (silver-gray film) with high reflectivity to infrared radiation as the surface layer of the fireproof and thermal insulation quilt on the construction site, its thermal insulation can be improved. Compared with the thermal insulation quilt with low reflection surface of infrared radiation, the heat transfer coefficient of thermal insulation quilt with high reflectivity surface such as aluminum foil film or aluminized film will be reduced by 2%~8%. When the reduction range is higher than that of the high reflectivity lower surface, the heat transfer coefficient is greatly reduced when the high reflectivity surface is used on both sides of the thermal insulation quilt. The thermal insulation performance of the thermal insulation quilt material is evaluated by the thermal conductivity coefficient for materials that transfer heat in the form of heat conduction. Induced heat flow through a unit area of ​​a covering material. Glue-sprayed cotton, non-bonded cotton, polyethylene closed-cell foam, pearl cotton and other materials are all excellent thermal insulation materials. Its light weight is beneficial to reduce the load of the quilt, but on the other hand, it is easy to be tilted by strong winds, causing cold air to be poured in and reducing its thermal insulation. Therefore, the insulation quilt needs to be lapped firmly in blocks, and the quilt should be pressed firmly when it is covered in use.
