Timing refers to the specified time, quantitative refers to the number of specifications, the fixed quantitative polyurethane spraying machine sprays the specified amount of polyurethane within the specified time, and the program control of the pouring equipment is very accurate, continuous and rapid construction.
The multi-station construction efficiency of the timing and quantitative polyurethane spraying machine is high
Timing and quantitative polyurethane spraying machine has a wide range of uses, such as polyurethane spraying between layers of heat insulation pipes, the middle layer of anti-theft doors, aluminum alloy profiles, heat insulation pipes, etc.
The dimensional stability of polyurethane thermal insulation spray foam refers to the irreversible dimensional changes in three-dimensional directions perpendicular to each other after the material is placed in a specific environment for a certain period of time. The magnitude of this change is related to the type and structure of rigid polyurethane foam. Density, molding conditions and other factors related to the thermal conductivity of the polyurethane rigid foam at the initial stage of molding have low thermal conductivity. After 24 hours, as the aging time increases, the cell structure gradually stabilizes, and its thermal conductivity also tends to stabilize. The reason is that in the initial stage of molding, the air pressure in the bubbles and the content of blowing agent are relatively high. As the aging time increases, the thermal conductivity value tends to stabilize. Due to gas diffusion, polyurethane foams. The bubble structure gradually stabilized.
The application of fixed-quantity polyurethane spraying machine in the field of building energy saving is limited, mainly because its cost is higher than the cost of EPS and XPS insulation materials. The rigid foam polyurethane insulation material synthesized by isovalerate, triethanolamine, polyether, polyol and various additives was studied, and the influence of each reaction component on the performance of the insulation material was explored, thereby forming a better formula. Reduce synthesis costs.
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
Polyurea spraying equipment can be applied to building roofs, tunnels, subways, waterproofing of roadbeds, production of foam membranes and TV props, internal and external corrosion protection of pipelines, auxiliary cofferdam works, corrosion prevention of storage tanks and chemical tanks, pipeline
As we all know, polyurea spraying equipment is an essential tool in life, because of his wide range, multi-purpose, so that we not only in the enterprise even our life also change together. Then want to use good polyurea spraying equipment is not so easy, this time I will bring you after the use of
Polyurethane rigid foam in the state before molding is two kinds of liquid, in the molding of these two kinds of liquid mixing, through the polyurethane spraying machine to become a solid raw material, so the construction molding method is more mobile. As long as it is not crushed polyurethane rigid
