Q:Are there any construction waste materials for composite thermal insulation bricks?
The strength products are made of high quality tabular corundum and mullite as aggregate, silicon carbide as matrix, additional special additive and a small amount of rare earth oxide to be mixed, and then formed by high pressure molding and high temperature sintering.
Q:What is the exterior wall insulation material made of graphite?
Graphite polystyrene (SEPS) containing graphite particles special, can be like a mirror which contains thermal radiation, and can greatly enhance the heat insulation performance of the infrared absorption, thereby reducing the heat loss of housing. Its insulation capacity is at least 30% higher than the average EPS, helping to increase energy efficiency and reduce carbon dioxide emissions.
Q:What are the specifications of high strength diatomite insulating bricks?
In view of the old and new concrete, steel structure, solid brick wall, hollow brick wall, compressed air brick wall and different brick wall, combined with the company installation patent method, it is suitable for the construction and installation of various types of wall. At the same time, it is also suitable for old house reconstruction. It has excellent outdoor weather resistance, color retention, alkali resistance, water resistance, scrub resistance, crack resistance, temperature resistance, waterproof, wear-resistant, collision resistant, and durable film, adhesion, and excellent anti mildew effect.
Q:Difference between inorganic insulation material and organic thermal insulation material
The main difference between inorganic insulation materials and organic thermal insulation materials is that the types of insulation materials are different:1, inorganic insulation materials, including glass wool, rock wool, expansion perlite, micro nano insulation board;2, organic insulation materials are mainly polyurethane foam, polystyrene board, phenolic foam and so on.
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 difference between the production line of foamed cement insulation bricks and the self thermal insulation block production line?
I still feel that the special is better, specializing in the production of a product, at least quality and after-sale protection!
Q:Coke burns in a closed house. Will anyone suffocate in it?
Not suffocating in the short term, will suffocate for a long time.
Q:What are insulation bricks for? Do not use high-rise buildings on the ah?
Heat preservation and heat insulation, that depends on the design of the drawing
Q:Insulation brick should pay attention to external walls?
Using special powder pointing pointing, check the horizontal joints and then hook the vertical slot, after cancelling the recessed brick outer surface 2mm, tile seam after hook silk or cotton cloth clean, after inspection of the large area pointing outside the walls, should be the implementation of a large area of local cleaning after cleaning, to ensure the whole project clean and beautiful.
Q:Can the whole wall of the high-rise building be made of grey insulation bricks?
If the frame structure, it may be so. What is the length of the whole wall? If it is longer, it is necessary to make a constructional column; if the hole is larger, the edge of the hole needs to be made into a border or a constructional column; if the entrance is small, the edge of the hole is about 300mm and needs solid bricks to build better. South wall thickness can be about 190mm, plus plastering design value of 200mm. Personal comments for reference!
