Small polyurethane foaming machine equipment has become the first choice for modern spraying technology. It is gradually replacing traditional spraying technology with the advantages of high efficiency, wide range and good effect. It has a wide range of applications in construction spraying and other related industries. Give you a brief introduction to some high-pressure foaming machine process principles and operating principles.
The principle of the polyurethane unitary foaming machine equipment is to use a high-pressure "plunger pump" to continuously deliver paint into the closed high-pressure paint pipe, so as to reach a high pressure of about 500-5000psi in the enclosed space, and then release the spray gun connected to the end of the high-pressure pipe Trigger to force the high-pressure "paint flow" through the extremely small nozzle (radius 0.1-0.5mm). When the high-pressure paint leaves the nozzle-contact with air and releases the pressure, it immediately expands violently and atomizes into very fine paint particles. To the surface of the coated object. With economic development and changes in people's concepts, it has become fashionable to use medium and high-end interior and exterior wall paints instead of mosaics and ceramic tiles to decorate walls in China. Water-based latex paint has become the most popular interior and exterior wall decoration material because of its non-toxicity, easy cleaning, colorful, and no pollution to environmental slag. But latex paint is a water-based paint with a high viscosity.
During the construction, the general manufacturers have very strict restrictions on the dilution of the original paint with water, generally 10%-30%. Excessive dilution will lead to poor film formation, and its texture, scrub resistance and durability will be damaged by varying degrees of alkali. The degree of damage is proportional to the degree of dilution, that is, the greater the degree of dilution, the worse the quality of the paint film. If strictly according to the manufacturer's dilution requirements, the latex paint will have a high viscosity and difficult construction. The most popular method in foreign countries is to use high-pressure airless spraying machine for construction.
From the above introduction, we know that the principle of the polyurethane foaming machine equipment is to pressurize the liquid paint into a gaseous state to increase the painting area, but this process is currently only used for large-area spraying construction. It is believed that with the continuous development of the industry, the scope of application of the spraying process in the future will be broader.
In many fields such as industrial protection and building waterproofing, polyurea materials have been widely used for their excellent performance advantages. In order to give full play to the characteristics of polyurea materials, a high-performance spraying equipment is crucial, and the CNMC-A25 po
