The glass fiber asphalt tile is a new type of tile shaped roof waterproof material, which is based on high-quality glass fiber felt, coated with high-quality petroleum asphalt, covered with calcined colored mineral particles on one side, and insulated materials on the other side. The quality of glass fiber mat is directly related to the service life of asphalt shingles; The formula of asphalt is very important, because the intensity of sunlight is different all the year round, the temperature difference is large, and the asphalt is subject to a great test, and the asphalt shingles are generally self-adhesive series, which requires that the tiles fixed on the roof play the function of self-adhesive strips on the premise of ensuring that the asphalt surface is not soft, not flowing, not hard, and not broken
2015/01/08 09:22:26 Safety signs, tools, instruments, electrical facilities and all kinds of equipment in high place operation must be checked before construction to ensure that they are in good condition before they can be put into use. Climbing and hanging high place operators and those who erect safety facilities for high place operations must receive professional technical training and pass professional examinations, take up their posts with certificates, and must undergo regular physical examination. The temporary catwalk or operating platform must be reliably tied or connected, and the safety net shall be fully covered below, temporary railings shall be set up on the side, skirting boards shall be set up, and close mesh safety vertical net shall be fully covered to prevent falling objects from hurting people. Reliable anti-skid measures must be taken when working at heights in rainy days. conduct...
2015/01/08 09:22:05 At present, with the rapid development of building decoration technology in China, more and more advanced building materials are used in building decoration, of which the integrated panel technology of external wall insulation and decoration is more advanced among many finishing technologies. At present, the external wall thermal insulation system in China is developing very fast. As a new type of wall thermal insulation material, the external wall thermal insulation decorative integrated panel has shown a good momentum of development. Traditional advanced exterior decoration materials, such as aluminum plate and stone curtain wall, can only use mineral wool or on-site polyurethane foaming agent to achieve the purpose of thermal insulation, which not only extends the construction period of exterior decoration, but also significantly increases the investment cost. Use new technology to
2015/01/08 09:21:23 Resin tile is a new generation of light environmental protection building material vigorously advocated and promoted by the country at present. The product is environmentally friendly, energy-saving, renewable and recyclable. Its unique performance advantages have won widespread attention and recognition from people in the construction industry. Xiaobian mainly introduces the performance advantages of resin tile as follows: 1. The resin tile has super weather resistance. Because of the characteristics of the material itself, it has extraordinary weather resistance in the natural environment, so it can maintain stable performance in any harsh environment. 2. Resin tile has good corrosion resistance. High weather resistance resin and main resin have very good corrosion resistance
2015/01/08 09:21:02 Most consumers and buyers will ask this question. In fact, one of the characteristics of fiber cement board that is different from other boards is its lightweight height. Before answering, briefly introduce the production process of fiber cement board, raw materials - molding - compression (ten thousand ton press) - demoulding - curing - steam curing - single piece drying, etc. If a manufacturer lacks a press machine, the plates of this manufacturer can be positioned without pressing plates, and the strength of the plates must not be good. If a manufacturer does not have steam curing equipment and monolithic drying equipment, then the strength of the plate is qualified, but the plate is easy to deform, especially not suitable for the external wall
2015/01/08 09:20:43 1. Specific gravity of plastic steel tile The main raw material of plastic steel tile is polyvinyl chloride (PVC). Its specific gravity is about 1.4. The plastic steel tile weighs 1 square meter of plastic tile. The weight divided by the volume is about 1.4, which proves that the main material of plastic tile is PVC and can effectively guarantee the service life of the product. The weight divided by the volume is greater than 1.4, which proves that a large amount of heavy calcium carbonate is added to the plastic tile to send other fillers, which not only cannot guarantee the service life of the plastic tile, but also the product is very fragile and easy to break, which can be applied to the proposed temporary buildings. 2. The plastic steel tile shall be ignited with a fire to ignite one corner of the plastic tile. After the fire source leaves, the flame will extinguish immediately. Fake and inferior models
