The pure polyurea of our company was successfully applied to the jiaozhou bay bridge in Qingdao, deducing the successful case of "turning the rotten into the magic". The reporter of peninsula metropolis daily interviewed professor huang, the technical director of the project, and made a special report on the project, the details are as follows.
There is a kind of damage, unlike the earthquake, typhoon as suddenly, it quietly, can let the bridge collapse, high-speed rail collapse, reservoir leakage, it caused a year of damage is greater than the sum of natural disasters 6 times, its name is "corrosion". Recently, the Chinese academy of sciences released a staggering figure, China's annual corrosion loss is equivalent to the output of 1.5 baosteel, China's 2010 corrosion loss of 1.2 trillion yuan, Qingdao's annual corrosion loss of more than 15 billion yuan. Happily, Qingdao's jiaozhou bay bridge, Olympic venues and other high-tech enterprises have been put on "protective clothing", can protect for a hundred years. On November 1st and 2nd, our reporter went deep into the anti-corrosion site and anti-corrosion laboratory to reveal this layer of protective clothing.
The construction site
Wearing a leather jacket in a leaky canal
Just to put on the jiaozhou bay bridge "protective clothing", Qingdao sand wood international trade co., LTD. Yang's phone rang off the top of his head as he picked up another project in nanjing. "since we introduced the polyurea technology developed by the functional materials research institute of Qingdao university of technology, we've been looking for partners one by one," he said. Yang yong, who only gets five hours of sleep a day recently.
November 1 at noon, the reporter came to the chengyang district cotton community, 200 meters away from the shuyuan reservoir diversion canal, a rough tent of about 25 square meters was set up, all the people are still busy on the site.
"Apply a little more force here, spread it evenly and keep up." Known as the "father of China's polyurea", professor huang, director of the institute of functional materials at Qingdao university of technology, has been paying attention to the transformation of scientific research results at different construction sites. The technician carried a 60-meter long white pipe on his right shoulder. He held an "airbrush" in his right hand and a heated pipe in his left hand. The pipe wrapped around the technician like a "snake".
Reduce the leakage of drinking water by more than 30%
At the other end of the tube were two large drums, one red and one blue. The tubes were made of yellowish material and the other blue was pale white. Under the action of the machine, the materials in the two barrels are input into the white tube. Press the button connected to the "gun", and the two materials are ejected together, showing a grey-white color. Professor huang said: "actually want what kind of color can be ejected, two types of material in the light yellow is necessary, the other kind of material can be required according to the color configuration.
The reporter climbed down two meters of the canal, see the surface of the canal pitted, this part is not put on the "protective clothing", and then go a paragraph, is the surface of the clean place, "this is treated. After being processed by the "gunners", the canal floor after spraying the materials is elastic and very flat, which looks like a leather carpet, huang said.
"A lot of drinking water is wasted because of the long duration of the canal and the cracks in the concrete structure of the canal." In the field responsible for the entire college reservoir project renovation manager told reporters, after an open tender, they chose the "polyurea" technology, to the canal wear this layer of "leather", at least 30 percent of the water leakage can reduce waste.
