As a new coating material, polyurea has changed the concept and cognition of previous coatings by engineers and added new knowledge of coatings. Since the polyurea coating can withstand the full impact of a sledgehammer and the most severe abrasion, and at the same time has satisfactory flexibility, the coating film will not crack even if the obvious expansion and contraction causes the concrete cracking or the steel structure deformation. Under abnormal conditions such as outstanding pipelines and sinking, it can still cover the entire surface of the workpiece. Let's take a look at the detailed composition of polyurea spraying.
1. Polyurea spraying: It is an elastomer substance produced by the reaction of amino compound component and isocyanate component. Isocyanates can be both aromatic and aliphatic. The amino compound component in between can be monomers, polymers, isocyanate derivatives, prepolymers and semi-prepolymers.
2. Prepolymers and semi-prepolymers are made by reacting amino-terminated or hydroxyl-terminated compounds with isocyanate. The R component must be composed of an amino-terminated resin and an amino-terminated chain extender. The amino-terminated resin must not contain any hydroxyl components and catalysts, but can contain additives that facilitate the dispersion of the pigment.
On June 8, the CNMC-A25 polyurea spraying machine produced by Hightop Group was loaded in Hightop Group Industrial Park and will be exported to Italy. CNMC-A25 polyurea spraying machine is widely used in industrial maintenance, tunnel, subway, roadbed waterproofing, foam film and television props pr

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
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
