The importance of polyurea in daily life determines the quality of life. For example, the waterproof performance of swimming pools using this product has been highly praised, so the editor and the big guys will take a look at how to effectively waterproof the polyurethane sprayer in the swimming pool.
The application and development of regular quantitative polyurethane spraying machines in the field of energy-saving construction enterprises are subject to certain restrictions. The main part of the reason in China is that its cost is higher than the market price of EPS and XPS insulation engineering materials. Research on rigid foam polyurethane insulation materials synthesized with isosine ester, triethanolamine, combined polyethers, polyols and various additives as raw materials, and explore the influence of each reaction component on the performance of insulation materials to form a better Formula, reduce the company's synthetic production costs.
The polyurethane sprayer device is an elastomer made by the reaction of isocyanate components and amino molecular compounds. They have multiple functions such as water resistance, corrosion resistance, and wear resistance. Waterproofing gives polyurea considerable advantages in the fields of polyurea waterproofing for expansion tunnels, stadiums and swimming pools.
The advantages of polyurea are as follows:
No catalyst, fast curing, any curved surface, inclined surface, vertical surface can be sprayed and formed, no flow phenomenon. Gel can be achieved in 5 seconds, and walking power can be achieved in 1 minute;
It is not sensitive to humidity and humidity, and can not be affected by the temperature and humidity of the social environment during construction;
A full set of spraying and pouring equipment, convenient construction and large power;
Excellent physical properties, such as tensile strength, flexibility, aging resistance, media resistance, abrasion resistance, etc.
On April 12, 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
Due to the demand of the production scale, many manufacturers will choose small polyurethane infusion foaming machine to help products for foaming, which can be more convenient for bonding, and in the subsequent use of the process is also more convenient for maintenance. So what are the characterist
Spring Festival does not close, for this year's Spring Festival holiday, CNMC Machinery's Ali International Station store got a good start. We started the year with a salesman, we harvested more than 1.4 million in sales, of which the largest single order reached one million.CNMC Machinery is a subs
Polyurethane sprayers may require special coatings and construction parameters when working with certain specialized types of wood. The following are some common types of specialty woods:
