Application of polyurea coatings in life
Spray Polyured Waterproofing Coating is an advanced and highly safe coating imported from abroad. Continuously improve and perfect in combination with relevant domestic scientific research units. The polyurea coatings currently sold in the domestic market have the characteristics of solvent-free, pollution-free, and highly reactive protection.
The polyurethane on-site foaming equipment consists of a two-component A, B, solvent-free, fast-curing green and environmentally friendly elastic waterproof material, which is divided into high-elastic spraying (pure) polyurea waterproof coating (JNC) according to different film-forming reaction groups And high-elastic spray polyurethane (urea) (commonly known as semi-polyurea) elastic waterproof coating (JNJ), according to the physical properties is divided into type I and type II. The components A and B are mixed and sprayed in the spray gun of the special spraying equipment, and react and cure quickly to form an elastomer waterproof film. High-elastic spray (pure) polyurea waterproof coating A component is a semi-prepolymer prepared by reacting a hydroxyl-terminated compound with an isocyanate; the B component is a mixture composed of an amino-terminated resin and an amino-terminated chain extender. Contains any hydroxyl components and catalysts, but it is allowed to contain Shaoli pigments and dispersing additives.
The A component of the polyurethane field foaming equipment waterproof coating is a semi-prepolymer prepared by the reaction of a hydroxyl-terminated compound and isocyanic acid; the B component is a mixture of a hydroxyl-terminated resin or an amino-terminated resin and an amino-terminated chain extender. The B component can contain a catalyst for improving the reaction activity, and it is allowed to contain oligomeric pigments and dispersing additives. This product needs to be sprayed and formed by special professional construction machinery when forming a film. Its excellent physical and chemical performance indicators, convenient construction technology, integrity of the waterproof and anti-corrosion system, and environmental protection are beyond the reach of any other traditional protective materials and technologies. It is widely used in urban subway, high-speed railway, tunnel and bridge, water conservancy and electromechanical, marine chemical industry, military and civilian projects for waterproof, anti-corrosion, abrasion resistance and "two prevention and one resistance" projects.
Now, with the improvement of residents' material consumption level, people's requirements for the living environment are constantly changing. Environmental comfort, safety, and environmental protection have become the leading direction pursued by modern people. Traditional home improvement coatings are gradually abandoned by the market. Because traditional coatings can no longer meet the needs of modern interiors. The appearance of toxic paint, pungent smell paint, and inferior paint makes people fearful and has a serious impact on the human body. Now, it is replaced by polyurea coatings with very high safety performance.
High-pressure foaming machine, also known as foam generator, the product of the foaming machine is foam, and what we need in the production process is also foam. In the work, polyurethane foaming has to go through two stages of foaming and curing.The high-pressure foaming machine will present variou
As a common product, high-pressure foaming machine has widely appeared in our real life, and the development trend is increasing:1. Polyurethane products are made of isocyanate and polyether as the main raw materials. Under the action of various additives such as blowing agent, catalyst, flame retar
The high-pressure foaming machine works for a long time, it is easy to heat up too high, what are the ways to cool down?Today, I will talk to you about the temperature reduction of the high-pressure foaming machine.Large flow box type high pressure foaming machineWhen using a high-pressure foaming m
Because foaming relies on heat, if there is no heat, the foaming agent in the system cannot evaporate and foam plastic cannot be formed. The heat comes from two aspects, one is the heat produced by the chemical reaction, and the other is the heat provided by the environment. The heat of chemical rea
A considerable part of auto parts, especially interior parts, are polyurethane foam products.

Polyurethane foaming machine is a large-scale equipment, which is used in many production enterprises. The emergence of polyurethane foaming machine production line provides companies with a lot of convenience, and the performance of this equipment is also very good in all aspects. Many people are m
The high-pressure precision foaming machine is carefully designed by the designer according to the user, and there are many models of it. Users can choose the model that suits them according to their needs to purchase. The high-pressure precision foaming machine in the market is economical. It is ve
1. Raw material system. The pressure of the raw material tank should be dry air, and nitrogen should be used as much as possible. Before starting the machine every day, turn the turntable of the raw material filter to the left or right a few times, and remove 200~300ml of raw material from the botto
What are the key factors that affect the foaming process of the high-pressure foaming machine? As long as the polyurethane component materials (isocyanate component and polyether polyol component), the performance indicators meet the formula requirements. A high-pressure foaming machine can produce
