Introduction of cork board construction technology
Cork construction technology, first of all, you have to understand what cork is, and the general construction technology is divided into many kinds. At this time, you should know that cork board is not wood, but rubber bark with a long history. Although cork building technology is a kind of building technology, it contains high-tech content. People keep discovering new energy. Cork material, that is, rubber, now plays an irreplaceable role in people's lives. The construction technology of cork board is a technology worth learning. To understand its construction technology, we need to pick up the definition, characteristics and so on of cork board. The following is the specific content.

Cork, commonly known as cork (Quercus variabilis), is not wood, but the bark of oak. Oak is one of the oldest existing tree species in the world, with a history of about 60 million years. At present, the cork resources in the world are mainly concentrated in the Mediterranean coast, especially in Portugal, which is known as the "cork kingdom", accounting for 30% of the world's oak resources, 50% of the raw material output and 90% of the cork products output. Oak is a special tree species. If its bark is picked regularly, it will not only die, but also grow new bark, and the raw material of cork message board is the bark of these oak trees. Features. Cork has a series of excellent characteristics, such as low density, compressibility, elasticity, air tightness, waterproof, moisture-proof, oil resistance, acid resistance, vibration reduction, sound insulation, heat insulation, flame retardant, insulation and wear resistance, and is loved by thousands of people. In addition, cork board has the characteristics of mildew resistance, heat preservation, sound absorption, silence and so on, and is more loved by people. Applicable place. Bulletin board is an ideal tool for companies, offices and schools to publish news, notices, plans, demonstrations and announcements.

Cork is made by crushing cinnamon bark into particles, mixing with chloroprene phenolic glue in a certain proportion, heating and pressurizing, and vulcanizing. Sound insulation and sound absorption, but also anti-slip, suitable for libraries, scientific research buildings, computer rooms and other types of buildings that need to be quiet. The construction of the cork floor in the reading room project of Beijing Library is introduced as follows: 1. The properties of the material and binder are 1. The common specification of technical performance of cork board is 300× 300× 5 (mm); Cork content: above 75%; Product density: 0.5 ~ 0.9g/cm ~ 3;; Tensile strength: 15 kg/cm ~3 or more; Hardness: Shore 70 or above, and has good elasticity.

The construction of cork insulation layer introduces the concepts of cork and cork insulation layer, the working conditions and machines needed for the construction of cork insulation layer. The technological process and operation characteristics of cork construction are emphatically expounded, especially the boiling of No.60 asphalt material, the preparation of cork, the division of elastic line on the surface of base course and the determination of position. Points for attention in construction and quality standards to be achieved are pointed out.

Cork board is made by crushing school bark into particles, mixing with chloroprene phenolic glue in a certain proportion, heating and pressurizing, and vulcanizing. Sound insulation, sound absorption, anti-skid, suitable for libraries, scientific research buildings, electronic computer rooms and other buildings that need to be quiet. The construction of the cork floor in the reading room project of Beijing Library is introduced as follows: 1. The properties of the material and binder are 1. The common specifications of cork technical performance are: 300 fire, 300 xs (mm), cork content: above 75%, product density: 0.5~0.9 g/cm3, tensile strength: above kg/cm2, hardness: above 70 Shore. Boiling water test: the volume change rate is less than 20%, and there is no damage. The change rate of l00'C×70 hours after hot air aging is less than 0- 10, and the flexibility multiple is less than 10 times. Bearing load: 2 1 kg/cm' has normal compressibility and is not damaged. Ex-factory price 25 yuan/m2. 2. Performance of adhesive The adhesive used for bonding chloroprene rubber cork board is Cx-40 1 adhesive, which is a chloroprene rubber-phenolic adhesive modified by chloroprene rubber. Neoprene rubber is the most widely used rubber adhesive at present, which is usually made of neoprene, zinc oxide, magnesium oxide, antioxidant and so on.

Cork can be used in many places, such as message boards, photo walls, bulletin boards, note boards and so on. You can arrange photos, documents and notes on the board with pushpins, which is very convenient.

The construction technology of cork board is a unique skill. In the process of understanding, you can know what you don't know, such as cork board is rubber or leather, which has many special functions. The cork board construction technology is different from other construction technologies, and the problems needing attention are also the key points. You really should take a good look at the construction technology of cork board.
