How does the polyurea spraying machine effectively prevent concrete from cracking?
The adhesive material of the polyurea spraying equipment is attached to the component parts of the composite floor. It has the integrity of the outermost layer, has no gaps, and has excellent leakage resistance. From the point of view of specific structure, the many advantages of polyurea spray have become more obvious. In some ways, special spraying devices are used during the entire spraying process. Polyurea spraying has a highly complete water protection structure, avoids the possibility of joint leakage, and can greatly improve construction efficiency. Because of this, compared with the existing common protective materials for water, the performance of polyurea spraying technology is more reliable and more environmentally friendly.
The biggest advantage of polyurea spray equipment materials is its excellent elasticity. Because of this advantage, it is an ideal protective material for floor concrete. As everyone knows, concrete materials are extremely easy to open and crack, and their durability at some extreme temperatures is extremely low. Extreme conditions such as opening cracks may occur when tested at some extremes or high temperatures. Polyurea materials are easy to manufacture and make up for some of the shortcomings of this type of concrete. The cracked pattern spreads very well. Concrete often bears stress (the internal force per unit area at a certain point of the examined section is called stress) and cracks, while the outer protected polyurea material will not crack, but the concrete chips will stick tightly. Together. Its soft and tough characteristics and high mechanical strength can prevent concrete openings from cracking even in bad weather, because of this it provides excellent water protection and protection.
Polyurea spray equipment can be divided into flexible polyurea for water protection, overweight polyurea that prevents metals from being corroded by oxidants, and polyurea that is resistant to abrasion. Polyurea coating is widely used in the playing field for its bright colors, flexibility and long life cycle. In high-speed iron mines, film and television props, theme parks and many other fields, the use of polyurea spraying equipment can improve the quality and speed of construction.
Because the site environment is more complex, the shapes of the coated objects are different, and there are many related related influencing factors, such as the size of the wind, the roughness of the substrate, the skill of the construction staff, and the construction star. Paint loss, customer demand, construction technology, etc. will all increase material consumption and cost.
Among many liquid on-site pouring film-forming materials, on-site adaptability is particularly important. No single material can do it. Without excellent primer (the first layer of the paint system), tight sealants, repair materials, etc., the effective time performance of on-site architectural coatings cannot be obtained. These auxiliary materials are necessary materials for perfecting detailed nodes and dealing with difficult projects.
