Smaller size urethane foaming machine is a device for infusion and foaming of polyurethane foam and plastic. As long as the performance indicators of the polyurethane component raw materials (isocyanate component and polyether polyol component) meet the requirements of the formula. Passing through this equipment can produce uniform and qualified foam products. It is made of polyether polyol and polyisocyanate in the presence of a variety of chemical additives such as blowing agent, catalyst, emulsifier, etc., through chemical reaction to foam and prepare foam and plastic.
Polyurethane foaming machine
1. Purpose
Used in the production of rigid, semi-rigid or soft polyurethane products, refrigerators (English: Refrigerator) freezers, automobile, motorcycle seat cushions, instrument panels, insulation pipes, building materials sandwich panels, furniture, etc.
2. Features
High and low voltage cycle switching device, switch between working and non-working
The combined device, the selected application L-type high-pressure self-cleaning combined head, the nozzle diameter is adjustable, and the high pressure forms a mist to be uniformly combined.
The metering is accurate, the selected high-precision metering device ensures that the metering accuracy is ≤1%, and the metering pump is selected to use a magnetic connection, which will never leak, and has a service life of 1 million times.
Electrical control, the selected application is a 10-inch touch screen, PLC module control, temperature, pressure and pouring flow rate, 20 recipes are stored, and the degree of automation is high.
Polyurethane elastomers are typical multi-block copolymers, where the molecular chain consists of flexible chain segments with a glass transition temperature below room temperature and rigid chain segments with a glass transition temperature above room temperature. The oligomer polyol constitutes th
Cold storage spray polyurethane focuses on the overall seamless condition after spray foaming. Polyurethane has good density, insulation and cold resistance. It is basically a closed cell structure. It not only has excellent thermal insulation properties, but also has good resistance to freezing and
In order to select the shrinkage rate of large cast polyurethane elastomer products more accurately, the influences of process conditions, environmental factors and product structure on the shrinkage rate were systematically investigated, and the change curves of shrinkage rate with time were measur

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
For the polyurea spraying equipment should take how to recommend1, polyurea is a set of waterproof, anticorrosion, wear-resistant, protection of multiple performance materials, but there is a certain range of tolerance, polyurea's recommended temperature range for the use of -40 ℃ -120 ℃.2、 Polyurea
Polyurea waterproof and anti-corrosion construction is generally spraying operation, in front of the small series to tell you why the reason for spraying, I believe everyone should have understood, now is about the construction process of the problem, let's take a look at it.Summary of polyurea wate
One. Corrosion resistanceIn addition to hydrogen acid, concentrated nitric acid and some strong oxidants, polyurea coatings show good stability in acid, alkali, salt, seawater, oil and other media, in the salt spray medium to do a strengthening comparative experiment, 1000 hours later, polyurea and
1. Increase efficiencyThere's a reason operators don't like manual mixing. It's a repetitive, physically demanding, and inefficient job. This includes manual heating and mixing of elements, trying to guess the correct dosage and loading the mixed paint into the spray system. It's becoming increasing
