Polyurea is an isocyanate component and amino compound composition of the reaction of the formation of an elastomeric material, the most basic feature is corrosion, water, wear and so on. Polyurea coating is mainly used in long-distance transmission of oil (gas, water) pipes, tank coffers and mining conveyor belt, hairdryer and other fields,and that has achieved very good waterproof, non-slip, wear, acid, alkali, aging, impact resistance and economic, social and environmental benefits.
Polyurea coating process to break the traditional anti-corrosion coating needs to heat and winding defects, a spray thickness of up to 1 ~ 2mm, so that the coating process greatly simplified. The coating does not contain organic solvents, the appearance of continuous, dense, seamless.
Polyurea spray repair has the following advantages:
1, without catalyst, fast curing, can be in any surface, slope and vertical surface spray molding, does not produce flow phenomenon, coating dense, continuous, seamless, protective performance is very prominent.
2, the moisture, moisture is not sensitive to the construction from the ambient temperature and humidity, the material protection and spraying technology organically combine to greatly improve the quality and progress of the project.
3, the use of complete sets of spraying, pouring equipment, construction convenience, high efficiency. A device to be 3 to 4 people operating, the daily construction of more than 1000 square meters, is the traditional process of 15 to 20 times, to minimize the impact of the weather on the progress of the construction.
4, the material is flexible, high strength, corrosion resistance, anti-aging, repair the conveyor belt up to the original belt with several times the service life.
5, two-component, 100% solid content, in the construction and use, are non-toxic, non-polluting, known as "green materials, green technology."
6. Has good thermal stability, can be used at 150 ℃ for a long time, and it can withstand 350 ℃ short-term thermal shock.
