Q:Advantages and disadvantages of wall insulation system?
Disadvantages: high cost, difficult construction (especially high-rise), construction technology requirements, the effect of high wall decoration (wall tiling and high technological requirements).
Q:What are the new types of building brick materials?
The whole material made of brick and mortar is one of the most widely used building materials. According to whether the masonry is reinforced, it is divided into unreinforced brick masonry and reinforced brick masonry.
Q:Does the building with the exterior wall thermal insulation brick require adding an angle steel bracket in the middle of the brick?
The first thing the man has to do is to do the quality test in front of the wall. As for the second, there is not much to do.
Q:What is the maximum temperature range of high temperature resistant insulation materials?
A class of inorganic non-metallic materials with a refractoriness of not less than 1580 degrees. Refractoriness is defined as the temperature of a sample of a refractory cone sample that resists high temperature without loading and does not soften and melt down. But only in terms of fire resistance can not be fully described refractories, 1580 degrees of temperature is not absolute.
Q:What is a JQK composite lightweight thermal insulation brick?
1. structural layer2. leveling layer3. waterproof layer4. thermal insulation layer and decorative layer
Q:What is the price of fireproof insulation material?
Fire insulation materials are various, different specifications, grades of prices are different, according to market rules, there will be fluctuation, the most commonly used are insulation rock wool, insulation board, insulation bricks, fire blocking materials.
Q:There are several construction techniques for exterior wall insulation
Exterior wall internal insulation technologyThe interior heat preservation of the wall is to place the heat insulation material on the inside of the outer wall.Advantage:1) waterproof, weather resistance and other technical indicators of finishes and insulation material requirements are not very high, gypsum board, gypsum plaster mortar can meet the use requirement, convenient;2) the internal insulation material is separated by the floor slab and is only constructed within a high storey without scaffolding;3) in the hot summer and cold winter and hot summer and warm winter zone, the inner heat preservation can meet the requirement;4) for the energy transformation of existing buildings, especially at a time when the housing sold to individuals, the whole building (source: China insulation network) or the entire district unified reform is difficult, only by the possibility of a large number of internal insulation. Therefore, in recent years, the exterior wall insulation has also been widely used.Shortcoming:1) because of beam, slab, structural column will cause thermal bridges, more heat loss;2) due to the material, structure, construction and other reasons, the cracking of the facing layer;3) it is not convenient for users to decorate two times and hang ornaments;4) occupy indoor use space;5) the energy saving of the existing buildings is very disturbing to the daily life of the residents.6) wall under outdoor climate, the temperature difference between day and night and the large temperature difference between summer and winter, easy to cause the wall cracking.
Q:What is composite sintering insulation bricks?
Taking the Yangtze River, lake and silt as the main raw materials, the performance indexes of roasting are in line with the technical specifications and technical requirements of the building blocks, referred to as insulating bricks.
Q:Insulation brick should pay attention to external walls?
Construction at room temperature, 24h after spraying water conservation, water spraying should not be too much, not flow. Unsuitable for winter construction. According to the national standard, seven consecutive days and nights, the average temperature is less than 5 degrees, may not carry on the external wall insulation, brick construction.
Q:Are there any special requirements for the use of raw materials in thermal insulation brick production equipment? What about the raw materials?
Specific funding, different production, different raw materials configuration will be different. According to the design requirements, refining production process, for production process, production management level, complete monitoring, pulping system on the lower computer, based on control level; lower machine by the programmable controller (PLC) is mainly composed of a crushing system. The host computer takes the standard industrial control computer (IPC) as the main man-machine interface (HMI) and beating system, and if possible, it is recommended to investigate on site
