Intelligent Building

Stories about the intellectual home is nothing new. Systems 'smart home' are becoming more popular worldwide, and in our country, including, but many still shy away at the mention of automation systems home as something of a distant and totally adapted to our Russian reality. The idea of making the building 'intelligent' originated in the United States. First appeared Intelligence building (intelligent buildings), which were based on the use of structured cabling systems. Such systems allow using the same cable to provide job exchanges, computer network, security, etc.

Then the system began to emerge multiplexed communication channels, allowing a single cable to transmit a variety of information simultaneously. The concept of smart home has been formulated in the 70s of the 20th century by the Institute of Intelligent Building in Washington as 'Building, providing a productive and efficient use of space. " In 1978, the company's X10 and Leviton USA have developed a technology to control household appliances in the household electric wires. The system allowed electric lighting control devices, and supported only six teams the power management. Further searches for ways to improve the automation and creation of new solutions captured many electronic company. For more information see this site: Crumpton Group. To date there are over a dozen different home automation technologies. So, what now constitute a system of 'smart home' is that they give the owners of dwellings, which are installed and how they are available to us mere philistines? Try to understand. So, the smart home – an intelligent control system that integrates into a single set all the equipment to perform various tasks in the field of security, livelihood, entertainment and communications.

Any smart home system consists of sensors, through which the received information, and actuators. One of the main advantages of intelligent buildings – it's comfort, they provide to their tenants. About how it's convenient for you to judge. The lighting control home and house infrastructure allows you to create different versions of light scenes, any combination, depending on the time days and moods at the touch of a button.

Polyurethane Foam Technologies

The first polyurethane foam invented (created) by Otto Bayer in 1947. First, polyurethanes have been used in industry as insulating boards, but in the seventies came the technological breakthrough in chemistry and began widespread use of polyurethane foam in aerosol (PUR). The first company packaged in a foam container was an English Royal Chemical Industry, but the first country, who used the foam in the construction, was Sweden – it happened at the beginning eighties, so that today the foam is a young and building products. Polyurethane foam in industry and construction for the production of modern foam need innovative recipe and product quality. A key indicator of success is the development of the Division of Research and Development appropriate chemical formulations, as well as overall quality control during production process. The consumer is required to use the goods in accordance with manufacturer's instructions on the label. Polyurethane foam – is a special product.

The foam is an excellent placeholder for the various voids and cracks and has good sound and heat insulation properties (1 santimmetr hardened foam on its properties correspond termichnym 1.4-1.8 cm polystyrene or mineral wool 1.75 cm). Also polyurethane foam has a high physical (density, performance), and mechanical properties: resistance to compression and rupture, adhesion to building materials. Practical application of a measure values of polyurethane foam. Polyurethane foam used for the installation of windows and doors, sound and heat insulation, fill the arches, the compounds of building materials, insulation and seal walls in buildings, cars and boats, as well as foam often perform construction work for general purposes. Differences between different types of polyurethane foam Consumers need to know the difference between the foam with tube and the foam designed under the gun. Standard polyurethane foam features a high density of 19-23 kg / m, and widespread in the market and a more affordable price.
