The 18th China (guangzhou) international building decoration fair a complete success



South China university of technology innovation of science and technology co., dalian on July 8, 2016-11, attended the 18th China (guangzhou) international building decoration fair, exhibited and innovative energy-saving Windows and doors matching solution, attract nearly person-times of professional audiences to visit and exchange.The products displayed in foaming equipment inspired professional audience for doors and Windows energy saving aspects of the new way of thinking, the use of low cost but, profiles, doors and Windows can be significantly reduced the production process of thermal conductivity by professional customer consistent high praise.

A. Foaming technique may reduce energy consumption resulted from air circulation of barrier-strip heat insulation molding. Non-foamed K-value is 2.3 to 3.5, and the K-value of foamed profile can be lowered to 1.5 to 2.

B. Preventing siphonage effect: PA66GF25 heat insulating strip has certain water absorption. In winter, steam generated from air circulation inside profile cavity is absorbed by heat insulating strip, and brittle rupture will occur when coefficient of linear expansion reaches 30%. This will not happen to the profile after foaming, and PU foaming absorbs no water.

Stopping convection phenomenon in barrier-strip cavity, and improving heat-insulating performance of doors and windows.

Preventing shrinkage of heat-insulating strip that will break away from connection due to freeze expansion after hydrops inside thermal-insulation cavity.


Help to improve profile`s integral rigidity.
Effectively making up for the insufficient press-in in profile`s insertion process that leads to defective goods.
