Polyurethane spray system applications in the field of building energy-saving products, services Description: Keywords: building energy efficiency, insulation, polyurethane, wall insulation, spray foam polyurethane foam material has excellent insulation properties, but its quick and easy way to spray foam molding, Polyurethane foam layer has good continuity and seamless nature; these characteristics of the product makes polyurethane spray foam molding in the field of building energy efficiency to a wide range of applications: 1, thermal insulation, good insulation properties, energy-saving effect is remarkable. Pu foam of low thermal conductivity, thermal insulation, good insulation effect it is unmatched by any other insulation materials. Use in the general residential buildings Pu waterproof foam insulation layer having a thickness of only one-third of traditional materials, and thermal resistance, but they nearly tripled. 2, roof load light. Pu foam density, light weight, light load for the roof when the roof, in the roof above the support plate part load, Pu foam roofing is the fourth traditional roofing practices, which is to improve the overall structure of the housing is very important to reduce the project cost and therefore more suitable for large span, shell roof construction. 3, to facilitate the construction progress of the project quickly. Pu Foam is a foam-forming calcium silicate board one board production Tai'an, process equipment is simple, easy to operate, can be sprayed can be cast, can at any complex surface construction work, usually construction by 3-4 people, press spraying layer thickness of 30 mm per day for about 500 square meters can be sprayed over the laying of traditional materials than tenfold increase efficiency Tai'an Which calcium silicate board one board, while also reducing the labor intensity and improve the working environment calcium silicate board one board, reduce the pollution of the environment. Pu foam-expansion foam liquid feedstock volume of 15-18 times, so that a small amount of raw material transportation. According to statistics, more than the use of traditional materials to reduce transport costs 80% of the vehicle, at the construction site also greatly reduces the workload of vertical transportation station classes. 4, good quality, long service life. How to determine the quality of marble slabs of marble is the role of the natural formation of the earth's crust millions of years, and it hard material, in the general situation of life of up to a few decades or even centuries. Selection of marble, from the color, pattern, capillary water absorption, hardness, etc. into account. Let's look at how to determine the specific quality marble: 1, in the purchase of marble stone by hand percussion test firmness, knocking marble surface, listening to its sound, feel touch, if the quality of sturdy stone the sound is crisp and solid feel Tai'an issued calcium silicate board one board manufacturers, in order to avoid cracks in the stone house to pick minor presence. 2, the stone surface structure was visually observed, the finer particles are more representative of the quality is good. 3, the structure of the surface if those cracks, there are risks in future easily broken, for the performance of the texture of the stone Omo who are not very beautiful. These are a few ways to judge the quality of marble, hoping to bring more knowledge to give customers some help, if in doubt, keep an eye on our website to ensure you have a windfall.
