Polyurea spray material is a new type of polymer material. Since this material has many different forms, and different forms of polyurea sprayers have many different characteristics, polyurea spray materials are widely used in contemporary society and industrial production.
As the thermal insulation effect of this material is gradually verified, the thermal insulation of polyurea sprayers has gradually become one of the common styles in the thermal insulation industry. This material is not only very good in insulation, but also has strong corrosion and water resistance, so even if this material is placed in some humid or corrosive environments, this kind of pipe can be used normally. If the insulation material of the polyurea sprayer is made of a plate and placed outside the wall, this kind of pipe can also play a very good role in preventing external factors from corroding the wall. In addition to being used as thermal insulation material, polyurea spray material can also be used as a raw material for making rollers, conveyor belts and shoe soles.
The traditional roofing waterproofing materials mainly include modified asphalt linoleum, SBS and APP modified linoleum, polymer waterproofing membrane and water-based paint. Traditional roofing waterproofing materials (such as asphalt, SBS, APP, etc.) will crack after aging in sunlight; that is to say, the material itself does not crack, but it will also break due to concrete cracking (caused by vibration, stress, weathering, etc.). There are a lot of seams in the waterproofing material, which can accelerate leakage as it ages outdoors. Once a leak occurs, it can be difficult to find the leak.
Polyurea material is completely superior to traditional waterproof material. Polyurea has excellent physical and chemical properties, high tensile strength, impact strength, flexibility, abrasion resistance, wet skid resistance, aging resistance and corrosion resistance. Jinghua Bangwei polyurea sprayer sprays on site, and the cured polyurea coating is 100% attached to the substrate, with good surface integrity, no joints, and good anti-leakage effect.
The two elastic waterproof polyurea materials were sprayed on the steel, concrete and asphalt surfaces respectively, and the surface of the sample at a distance of 30.5 cm from the coating was sprayed with -196 liquid nitrogen for 30 seconds without any damage to the coating; when the spraying distance decreased By 10.2 cm, the coating on the steel and concrete surfaces showed slight cracks, while the coating on the asphalt surface was intact. In addition, the concrete specimen coated with polyurea material fell freely from a height of 1.8 meters, and the concrete itself cracked, but the elastic waterproof polyurea material was not damaged, and the concrete fragments gathered together firmly. Because the elastic waterproof polyurea material has excellent flexibility, aging resistance and mechanical strength, even in the case of concrete cracking, the polyurea material not only does not break by itself, but also "holds" the concrete, thus achieving waterproofing and protection. effect. The elastic waterproof polyurea material is especially suitable for the waterproof treatment of the roof of the building to achieve the purpose of "once and for all".
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
