Common knowledge of coating: application prospect of pure polyurea coating in water conservancy industry

Core tip: in China, canal seepage control is the most widely used water-saving engineering technology, which can effectively improve the utilization rate of water, alleviate the problem of water delivery and supply, promote the development of national economy and protect the needs of people's living water The traditional canal seepage control materials include earth material, masonry, concrete, asphalt concrete and geomembrane material In recent years, canal anti-seepage engineering technology has been paid attention to and developed rapidly in the industry Many research results have been obtained in the aspects of anti-seepage materials, anti-seepage section structure and anti freezing technology Drinking water transmission equipment and pipelines are under the action of water flow scouring and alternating temperature for a long time, except for the requirements Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Paint House News: in China, canal seepage control is the most widely used water-saving engineering technology, which can effectively improve the utilization rate of water, alleviate the problem of water supply, promote the development of national economy and protect the needs of people's living water The traditional canal seepage control materials include earth material, masonry, concrete, asphalt concrete and geomembrane material In recent years, canal anti-seepage engineering technology has been paid attention to and developed rapidly in the industry Many research results have been obtained in the aspects of anti-seepage materials, anti-seepage section structure and anti freezing technology Drinking water transmission equipment and pipeline are in the role of water flow erosion and alternating temperature for a long time In addition to the ability of resisting erosion and temperature alternation, the material also needs to have excellent aging resistance The most important thing is that the material itself must be safe and non-toxic It is difficult for common coating materials to meet the above requirements at the same time Qtech-407 pure polyurea antibacterial material developed by Qingdao University of science and technology provides a reliable new technology and material for the protection of drinking water transmission equipment Qtech-407 pure polyurea antibacterial material is zero VOC, pollution-free, environment-friendly green environmental protection material In addition to its excellent mechanical properties, aging resistance, corrosion resistance, leakage resistance, impact resistance, fatigue resistance and other properties, the material also has good antibacterial and mildew resistance properties, and the material itself is non-toxic and harmless, with high safety In addition to its wide application prospect in drinking water delivery equipment, it can also be widely used in other fields with high health requirements, such as pharmaceutical industry Factory, hospital disinfection room and other places As a new type of anti-seepage coating, qtech-407 pure polyurea coating has the following advantages in the anti crack and anti-seepage engineering of diversion canal: 1 Excellent physical and chemical properties, high elasticity, high anti crack strength, outstanding anti scour and anti-seepage performance; 2 100% solid content, pure and non-toxic, suitable for domestic water facilities, in line with the hygienic requirements in the safety evaluation standard for drinking water transmission and distribution equipment and protective materials (GB / t17219-1998); 3 Rapid curing, can be put into use immediately after spraying, the top surface of facade construction does not hang; 4 Insensitive to environmental temperature and humidity, with good thermal stability; 5 Long service life, low long-term cost and high cost performance After immersion in water for 360 days, the tensile strength, elongation at break and hardness of qrech-407 pure polyurea coating are still high, and the change of mechanical properties of the material is small on the whole; the adhesion between the coating and the substrate shows a slow decline trend, but it can still reach 4.5MPa With these excellent physical and chemical properties, pure polyurea coating has gradually entered the water conservancy industry, especially in the field of urban residential water and canal irrigation Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
