The application of polyurethane insulation materials and the support of national policy for development

Release date:2017-03-18 Author:Shanghai yue ke new materials co. LTD Click:

With the international economic situation improving and the expected domestic monetary policy easing, the industrial economy has recovered. Industrial production must use polyurethane insulation material, is the industrial production precondition, it is to determine the economic benefit of the enterprise one of the factors.

Polyurethane insulation materials can effectively prevent heat exchange materials from becoming heat insulation materials. Polyurethane insulation material type is different, thermal conductivity is different. Pu heat preservation material of the material is different, its physical and thermal properties are different, and the polyurethane thermal insulation material and heat insulation mechanism has the difference, its thermal conductivity or coefficient of thermal conductivity will vary. The thermal conductivity of industrial heat insulation materials is often lower, and specific index requirements are closely related to the industry field and specific application conditions.

Most of our polyurethane insulation materials are mostly empty heat insulation materials. It is very good for us to create an appropriate life, which is one of the indispensable substances of human beings. But with the continuous development of human life, industry, science and technology under the condition of constant progress, pu heat preservation material of pu heat preservation performance requirements are constantly improve, pu heat preservation material and constantly improve the properties of improvement.

Pu heat preservation material with its light density is small, high strength, low coefficient of thermal conductivity of a variety of performance are widely used in domestic construction market and the rapid popularization and development of rigid polyurethane insulation materials can be made according to customer's require a variety of plate and pipe, tile, also can undertake on-site pouring foam assignments or spraying operations. The protective layer of polyurethane insulation material can be used to enhance the compressive strength and anti-corrosion ability of the insulating layer. It is mainly used for the two main applications of polyurethane insulation materials, such as storage tank, storage tank, pipe, insulation, wall panel and roof, etc.

1. Building insulation: including molding polystyrene board, extruded polystyrene board, spraying polyurethane hard foam etc. Polyurethane is the best choice at present. Polyurethane has become a mainstream product of building energy conservation and insulation materials. Insulation of the exterior wall of building insulation, used to polyurethane insulation material for a long time.

In building insulation: flat roof waterproof insulation. No man's roof is sprayed with a color coating as a protective layer. The man's roofing, on top of the slurry paving tile; Roof slope roof. The foaming polyurethane is sprayed on the lower edge of the watch board, and the tile slurry is on the watch board, which will not slide; Wall insulation. Foaming polyurethane for wall insulation is more advantageous. Assembly type big wall board, spray on the plate intercostal, the bond is good and tight. If the hollow block, the insulation decorative board, the foaming polyurethane can be sprayed in the hole, filling. The wall of the frozen bank, spray is preferred. At present, the key to the wall reform is the thermal insulation technology, and the foaming polyurethane can be a big project. The basement walls are insulated and waterproof, which is the part of the foaming polyurethane, which can be insulated, waterproof, and save other protective layers. Rigid polyurethane foam material in the domestic many building wall thermal insulation is widely used in engineering, and this kind of material with its have not bibulous, waterproof function, but also has excellent thermal insulation effect, become indispensable to the current building energy efficiency market new system insulation products, can replace the traditional waterproof and thermal insulation layer is widely used in roof and wall insulation. And there are multiple systems.

2, pipe insulation: the china-russia crude oil pipeline section using a variety of domestic technology and equipment in China: pipeline adopted normal temperature sealing oil process, local pipeline in rigid polyurethane foam insulation, protective layer of polyethylene plastic.

Building energy conservation is the basic state policy that the country adheres to for a long time and is an important measure to realize low carbon and green economy. Therefore, the building energy conservation thermal insulation effect must be higher and higher. Polyurethane insulation material is the most ideal building energy conservation material at home and abroad. It is a kind of comprehensive and excellent thermal insulation material which is indispensable for the realization of national building energy saving indexes. Polyurethane insulation materials can meet the requirements of fire safety performance under different situations. The fire safety performance can be achieved and must be done. By adjusting the molecular structure and flame retardant and smoke-suppression technology of polyurethane raw materials, it can be effectively developed into a polyurethane hard foam insulation material with low smoke density and low toxicity. Polyurethane inorganic composite thermal insulation materials, combining the non-combustibility of inorganic materials and the thermal insulation of polyurethane materials, will be the future development direction of thermal insulation materials.

Shanghai, the new material co., LTD., founded in 2006, is a structure of composite material technology providers and product manufacturers, focusing on high performance requirements and large structural composites provides overall solutions, mold design and manufacturing, the overall assembly line a total package, raw material supply. Main operation: epoxy system deformable agent, polyester system mold release agent, sealant and so on.
