[China Aluminum Industry Network] Recently, the “silanization†surface treatment technology for aluminum alloy profiles jointly developed by Hunan University and Haida Aluminum achieved major breakthroughs, obtained national invention patents, and was mass-produced in Changsha Haida Aluminum Industry Co., Ltd.
It is reported that at the 2008 China (Changsha) Science and Technology Achievement Transformation Fair, Changsha Haida Aluminum Industry Co., Ltd. as a “three hundred stars†company in Changsha was successfully contracted by Changsha City and Hunan University to jointly develop a “silanization†surface. Processing technology.
According to Zhang Jinlu, manager of technology development department of Haida Aluminum Co., Ltd., the silanization process is an environmentally friendly metal protection pretreatment technology. The silane film can be used as a pre-protection layer alone, and the silane film has a good binding force with the organic coating. , can significantly improve the adhesion of the coating and the metal matrix, in the past few years, the project team after repeated studies and experiments, "silanization" technology in Haida Aluminum successfully tested, Haida Aluminum successfully applied the technology to develop "gold "Silver family", "Purple gold dynasty", "Ruyi 818" series of products, once listed, has been highly recognized by the majority of users, the current supply of these new products exceeds demand, "the family of gold and silver, purple dynasty products not only look luxurious, but her resistance to decay The wear-resistance performance is even more enhanced. It is indeed a high degree of unity between classical beauty and modern technology." Zhang Jinzhang's manager told reporters with pride.
Haida Aluminum pays long-term attention to product innovation. The innovative research and development of technology and products has also enabled Haida to make rapid progress. In just five years, sales have grown from 70 million to seven billion.
It is reported that Haida's technical center was established at the end of 2005 and invested a total of 27.69 million yuan in the past five years. At present, there are 55 technical centers with 28 undergraduate degrees, 10 intermediate titles, and 5 senior engineers. Haida adheres to the open mode of operation and the third-level R&D system, and combines the three R&D models of external committee research and development, independent research and development, and full participation, to improve the independent research and development capabilities of the technology center.
Fibreglass Geogrid ( FG) Stitched With Nonwoven Geotextile Impregnated by Bitumen: Ultimate tensile Strengths from 8kN/m to 400kN/m . Biaxial, flexible high modulus Polyester geogrid stitched with nonwoven geotextile together impregnated with bitumen using the knitting process .
1. It reinforce old asphalt concrete road surface and asphalt layer, and prevents damage ;
2. It is used for rebuilding cement concrete road surface into composite road surface and restraining reflection caused by block contraction .
3. It is used in road expansion and improvment project and crack caused by old and new combination position and uneven sedimentation ;
4. It is used in soft soil base reinforcement treatment , is favorable for soft soil water separation and concretion,restrains sedimentation effectivly,distributes stress uniformly and improve overall strength of road base;
5. It is sued for preventing contraction crack caused by new road semi-rigid base layer,and reinforces and prevents road surface crack caused by foundation crack reflection.
