INTRODUCTION TO RELEVANT KNOWLEDGE OF POLYUREA SPRAYING EQUIPMENT ⑶

Polyurea spraying equipment is a highly reactive and pollution-free spraying technology developed in the past 20 years abroad. Its excellent physical and chemical properties, excellent manufacturability and environmental protection fully show its unparalleled superiority over traditional protection technology. So what is the application of the environmental protection of polyurea spray equipment materials in the construction field?

Application of environmental protection of polyurea spraying materials in construction

1. 100% solid content, no solvent, no organic matter volatilization, non-toxic, is a pollution-free green spraying technology.

2. Good water permeability resistance, seamless overall, dense tissue, toughness, strong adhesion, real "skin-like" waterproof. Polyurea can be used for waterproofing on the front and back water.

3. The elastomer coating of polyurea spray equipment can be used for a long time at -45℃～120℃, and the heat resistance can reach 160℃ (it can withstand the short-term thermal shock of 160℃).

4. Good weather resistance and aging resistance. Although aromatic polyurea has yellowing under ultraviolet rays, it has no chalking and cracking, and can be used for a long time. It is resistant to freezing and thawing, cold and heat shock and the alternating shock of wind, rain, frost and snow.

5. Excellent physical properties. Polyurea has outstanding characteristics such as tensile strength, tear strength, impact strength, bonding strength, elongation, abrasion resistance, puncture resistance, rolling resistance, puncture resistance, and slip resistance, and it has excellent resistance to concrete cracking Performance, protection against concrete cracking, and reinforcement of lost strength concrete structures.

6. Good anti-corrosion function. Polyurea can withstand long-term immersion in most corrosive media such as acid, alkali, salt, sea water, and chloride ions.

Polyurea spray equipment waterproof coating has the advantages of excellent waterproof performance, no joints, good adhesion, environmental protection, long service life, and high cost performance. It is a dream waterproof material in the construction industry. At present, the material has been widely used in high-speed railways, Olympic venues, roof waterproofing, pools, subways, tunnels and other fields. The use of spray polyurea equipment waterproof coating does not require maintenance, one-time investment, life-long benefit, it is the best choice for large-scale national waterproof projects such as high-speed railways and tunnels.

Our country's building roof waterproof materials have developed from a single bitumen variety to modified bitumen coils, polymer waterproof coils and waterproof coatings. There are a large number of joints in the waterproofing membrane, which can easily cause leakage. Let’s take a look at the application of polyurea spray equipment waterproofing in high-end roof construction.

 Application of Polyurea Spraying Equipment for Waterproofing in High-end Roofing Buildings

Polyurea spray equipment waterproof coatings are mainly polyurethane and water-based acrylic. Water-based acrylic paint has good weather resistance and is easy to clean. The disadvantage is that it cannot be applied under low temperature or high humidity conditions, and its high air permeability cannot seal water vapor. Polyurethane elastic waterproof coating has bright colors and good waterproof performance, but it is easy to foam under the influence of humidity during construction, the facade is easy to flow, and the aging resistance is not good.

The above-mentioned waterproof materials are more prone to cracking after aging in the sun. Even if the waterproof material itself does not crack, it will break due to the cracking of the concrete (caused by vibration, stress, weathering and other factors). SPUA material is different because of its high strength, good flexibility, and good aging resistance. Even when the concrete is cracked, it can hold the concrete tightly. It is especially suitable for the roof waterproof treatment of high-end buildings. If we want to completely eradicate the hidden danger of roof leaks and get out of the current construction industry's "repair every year, every year, more and more leaks", we must eventually come to SPUA technology, which has been well verified abroad.

The application of polyurea spray equipment technology to roof waterproofing of high-end buildings is a general trend. Its excellent cost performance will surely end the history of my country's "black roof" in the near future and make our city more colorful.

Polyurea spraying equipment paint is used in sewage treatment tanks, and a large amount of sewage containing corrosive media, such as acid, alkali, salt industrial wastewater, organic matter and oxidants; rainwater and sewage in oxidation ditch, have good waterproof and anti-corrosion effects. Today, I will take you to learn about the application of polyurea spray equipment coatings to industrial waterproof and anticorrosive treatment.

Application of Polyurea Spray Coating to Industrial Waterproof and Anticorrosive Treatment

To waterproof the metal roof with polyurea spray equipment, first of all, the details of the steel roof: metal plate seams, gutters, sinkholes, roof ridges and other parts that are prone to water leakage are partially blocked, and then the whole is sprayed with polyurea. The details are handled in a similar way to acrylic.

The addition of microorganisms and chlorine will also have a certain impact on the corrosion of reinforced concrete; the corrosion of industrial septic tanks is much stronger than that of domestic sewage tanks. For the selection of anti-corrosion layer, industrial wastewater treatment tanks should fully consider the characteristics of sewage corrosion in different industries, and appropriate anti-corrosion linings should be selected.

For anti-corrosion concrete structure anti-corrosion paint series and series, the corrosion degree of sewage is different. For the value series of corrosion degree of small sewage tank, compare the corresponding acid corrosion series high-strength, water-based paint, non-toxic and environmentally friendly. It will not cause harm to the body. It can also brush workers, spray mechanically, and use plasma spraying equipment. The weight of the equipment is only kilograms. There are three construction groups. Each shift can complete more than square meters, which greatly improves construction efficiency and ensures normal production. cycle.
