Q:How to distinguish between fluorocarbon paint and ordinary paint?

Fluorocarbon paint, also known as fluorocarbon paint, fluorocarbon paint is made of fluorocarbon resin, pigments, additives and other processing, is the most comprehensive performance of one of the best paint, fluorocarbon paint "paint king" reputation. Fluorocarbon paint is made of fluorocarbon resin, pigments, additives and other processing, is the most comprehensive performance of one of the best paint. Since the resin molecules contain the highest C-F bonds in the organics, the fluorocarbon paint has many special properties that are superior to ordinary coatings. Mainly in: weather resistance, salt tolerance, washability, non-sticky and so on. The above technical indicators are several times the ordinary paint. So the fluorocarbon paint "paint king" reputation. Fluorocarbon paint is widely used in oil tanks, underground underground oil pipelines, ships, steel structures, bridges, steel mills, power plants, transmission towers, chemical plants, port machinery and concrete. Anticorrosive coatings play a role in protecting iron and steel, nonferrous metals and concrete, preventing metal oxidation and cracking of concrete.

Q:The definition of the two components, it was said that the curing agent is anti-corrosion coating, I would like to know what is the difference between the two, is not anti-corrosion coating, including paint, paint is one of it, fire paint is what kind of

In the painting before the operation, we will be two sets of paint, respectively, with a dynamic mixer to fully stir evenly, add some special operations in the coating curing agent to help paint the concentration required for the construction of the curing agent when added , Add the side while stirring to ensure that the curing agent and paint can be fully integrated together.

Q:What kind of paint cost-effective, good recommendation?

When dyed, the reactive dyes are first dissolved in water, dyes and water molecules into the fiber at the same time, and the fibers are sorbed. The degree of absorption of the dye in the dye (color rate) depends on the affinity of the dye and the amount of electrolyte (salt, alkali, acid) in the dye solution.

Q:Who knows to help speak

Pigment characteristics Pigment is a kind of colored fine powder powder material, generally insoluble in water, oil, solvents and resins and other media, can be dispersed in a variety of media.It has hiding power, color strength, relatively stable light, Commonly used in the preparation of coatings, inks and colored plastics and rubber, and therefore also known as colorants. Pigments are organic or inorganic, colored, white or black material, dispersed in the medium almost insoluble. Color pigments are divided into organic and inorganic The characteristics of each of the past can be used to distinguish its type.

Q:What are the types of polymers that are classified by performance and use?

Rubber - in the greenhouse with high elasticity, even by a small external force deformation can be up to 10 times more, to the external force and then restore the original polymer. Such as styrene-butadiene rubber, butadiene rubber.

Q:Paint and the day the water on the human body what kind of harm

Long-term inhalation of benzene can lead to aplastic anemia.

Q:Are fluorescent pigments poisonous?

The pigment does not contain any radioactive elements and toxic heavy metals, so non-toxic, harmless, safe for the human body, is a new generation of green fluorescent pigments.
