Snow wax trucks are an important carrier of the "Science and Technology Winter Olympics" and are special vehicles for waxing athletes' skis. Located in Jinan Zhangqiu Mingshui Economic and Technological Development Zone, Shandong Kehua Saibang New Materials Co., Ltd., its self-developed ultra-low temperature impact-resistant composite materials are applied to the snow wax trucks of the Winter Olympics, which can meet the use of -55 °C ultra-low temperature environment and attract much attention on the world stage.
Delivered 4 months in advance, it can meet the use of -55 °C ultra-low temperature
Located in Mingshui Economic and Technological Development Zone, Shandong Kehua Saibang New Materials Co., Ltd. was established in 2015 by Shandong Hualing Cable Co., Ltd. and Shandong Academy of Sciences. The company mainly develops lightweight, ultra-low temperature, reinforced, toughened and other high-performance composite materials and related products.
According to the working conditions of the snow wax car resistant to low temperature use environment of the Winter Olympic Games, Cohua Saibang took the initiative to undertake the task of ultra-low temperature bumper and special development of the snow wax car. In December 2020, Cohua Saibang, together with the technical team of the Belarusian Academy of Sciences, established a special material project for snow wax car bumpers and ultra-low temperature stepping.
After nearly 5 months of research and development, Cohua Saibang and the Belarusian Academy of Sciences team, relying on the original ultra-low temperature material development experience and foundation, after nearly 100 times of formula debugging, laboratory testing work, completed the snow wax car ultra-low temperature material formula design, test work, and optimized the processing performance of the material, to ensure that the original bumper, step mold structure under the premise of not changing the original bumper, stepping mold structure, to meet the processing conditions, successfully developed a low temperature impact resistant bumper, strength, toughness, low temperature resistance performance have been greatly improved, Meet the ultra-low temperature -55 °C environment use.
From December 4 to 19, 2021, the snow wax truck equipped with Parts of Cohua Saibang went through nearly 10,000 kilometers of wind and sand in Xinjiang Hot Spring, Chongli, Hebei province and Yangpu in Shanghai, and the low temperature "pre-post trial" was tested to fully meet the design and use requirements.
According to Li Xiaoyu, executive general manager of Shandong Kehua Saibang New Materials Co., Ltd., the research and development cycle of similar projects is often more than two years, in order to successfully complete the task of helping the Winter Olympics, Kehua Saibang promoted experiments day and night, and basically completed the development of materials in less than 5 months, and completed the delivery with "extreme products and services" with high quality 4 months in advance.
After the appearance of the Winter Olympics, athletes from all over the world gave the snow wax car a very high evaluation, Li Xiaoyu said: "Some athletes said that this is the best snow wax car they have ever seen, and we are also very happy, the snow wax car represents Shandong's 'face'." ”
Rail transit, bridge construction, new materials are widely used
In addition to the snow wax car that has attracted much attention, in fact, from toys and air humidifiers, to high-speed rail, buildings, the application of new materials is everywhere.
It is understood that the preparation technology of ultra-low temperature toughening nylon materials of Minus 70 degrees Celsius has reached the world's leading level, completely replacing imported materials and being widely used in rail transit and other fields. The use of "new materials" made of high-protection safety helmets, cycling helmet series products, revolutionary use of high-performance low-temperature impact-resistant nylon composite material development, the protective performance is higher than the national standard 2-3 times, really do not smash and fall, to solve the problem of existing products below -10 °C can not guarantee safety. Carbon fiber composite material super strong new building formwork solves the traditional steel formwork, wood formwork high energy consumption, non-renewable difficulties, pain points, in the rail transit, highways, bridges and tunnels in the construction of shine.
Relying on the Belarusian National Academy of Sciences, Shandong Academy of Sciences advanced polymer materials technology achievements, transformation and cooperative development, at present, Kehua Saibang products have been widely used in military, rail transit, automobile manufacturing, sports equipment, civilian and other fields.
In Jinan's "Dongqiang" strategic map, new materials are one of the important pieces. At present, in the Zhangqiu Mingshui Economic and Technological Development Zone, Shandong Kehua Saibang New Materials Co., Ltd., Jinan Shengquan Group Co., Ltd. and other leading enterprises have "gathered" to grow, and to explore and expand the territory in the new material industry will also provide a new grip for Jinan's economic development.
