Can you believe it? After spraying polyurea in the bamboo basket, the bamboo basket can be used to fetch water to make it drip-proof; after spraying polyurea on the outside of the watermelon, no damage can be seen even if it is dropped from the 15th floor.
That's right, polyurea, the "king of coatings", was once known as "the great discovery in the field of coating technology in the 20th century". Its appearance also made the spraying technology leap forward. From truck containers, park sculptures, to reservoir dams, traffic bridges and tunnels, and even my country's aerospace military industry, nuclear power and wind power, its advent covers all aspects of our lives.
Therefore, there are many reasons for choosing polyurea spraying!
1. Good thermal stability, 120℃;
2. Two-component, 100% solid content, does not contain any volatile organic compounds (VOC), environmentally friendly;
3. The prototype has good reproducibility, and the surface is smooth, continuous, seamless, waterproof, anti-corrosion, anti-wear, and anti-scaling performance;
4. Excellent physical and chemical properties, such as tensile strength, elongation, flexibility, wear resistance, aging resistance, corrosion resistance;
5. It is not sensitive to humidity and temperature, and will not be affected by ambient temperature and humidity during construction. (Can be used on ice; can be used at -28°C; can be solidified in the freezer);
6. No catalyst, fast curing speed, can be sprayed on any curved, inclined and vertical surfaces without sagging. Gels in 5 seconds and reaches walking strength in 1 minute.
You must know that with the advancement of technology and the vigorous development of green industries, high-quality and high-efficiency products will always be welcomed by the market, while low-end and backward products will gradually be replaced.
One. Corrosion resistanceIn addition to hydrogen acid, concentrated nitric acid and some strong oxidants, polyurea coatings show good stability in acid, alkali, salt, seawater, oil and other media, in the salt spray medium to do a strengthening comparative experiment, 1000 hours later, polyurea and
1. Increase efficiencyThere's a reason operators don't like manual mixing. It's a repetitive, physically demanding, and inefficient job. This includes manual heating and mixing of elements, trying to guess the correct dosage and loading the mixed paint into the spray system. It's becoming increasing
The moon is very bright at the fifteenth day of the month, and the love is even stronger at the Mid-Autumn Festival; the Mid-Autumn Moon is the most round in a year, and the osmanthus rabbit is accompanied by Chang'e; the warmest thing on earth is the reunion, and we are looking forward to the night
On August 30th, Shandong Hightop Group went to Jining Children's Welfare Institution to carry out a donation activity of “Drops converge to become the sea of love and brighten the future”, and sent a batch of love materials to the children.In order to provide the most accurate care for the children,
What is a two-component sprayer?Two-component sprayer refers to the A/B component coatings, when spraying construction fusion spraying operation, or the main liquid material with the curing agent in the spraying construction according to a certain ratio of mixing spray, to achieve the best coating e
In the early 1970's Germany will custom polyurethane two-component liquid reaction molding technology, that is, RIM-PU technology commercialization to really promote the development of the custom polyurethane industry. Two-component rigid polyurethane liquid reaction molding process coup the traditi
The advantages of polyurea spraying equipment over manual hand brush construction:First, extremely high coating efficiency. Spraying efficiency is as high as 200-300 square meters per hour, more than 10 times that of traditional roller construction.Second, excellent surface quality. Spray coating is
As we all know, polyurethane is a widely used polymer material on the market, which can be used as adhesives, sealants, coatings, insulating materials, fillers, foaming materials, engineering plastics, rubber products, fibers and so on.And polyurea waterproof coating has gradually become familiar to
On August 2, CNMC-E3 polyurethane spraying machine was loaded in the industrial park and will be exported to France soon.CNMC-E3 polyurethane spraying machine is widely used in industrial maintenance, tunnel, subway, waterproofing of road base, production of foam film and television props, pipeline
Polyurethane temperature is too high when the reaction is violent and not easy to control easily injected into the larger box of the bubble liquid performance is not uniform, the beginning of the injection of the bubble liquid has been a chemical reaction, the viscosity increases rapidly after the i
