The spraying polyurea construction operation should be carried out under the conditions that the construction environment temperature is greater than 5°C, the relative humidity is less than 85%, and the base surface temperature is 3°C greater than the dew point temperature.
If the temperature of the construction environment is too low and the relative humidity in the air is too high, the moisture in the air is easy to condense on the surface of the base layer. Because the temperature of the material sprayed on the surface of the base layer is higher, and the crosslinking reaction exotherms, it is It is very easy to vaporize moisture, and then produce pinholes and holes in the rapid prototyping polyurea coating film defects, so it is particularly important to control the temperature and humidity of the construction environment.
During the spraying polyurea construction operation, if the wind speed is too high, it is difficult to operate, and the material is flying around, and it is difficult to form a uniform coating. Therefore, it is not suitable to perform spraying operations if the construction is in the open air environment with wind level 4 and above. Yes, spraying in the open air is strictly prohibited in rain and snow.
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
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
