China Pigment Carbon Black Supplier, Manufacturer For Polyurethane Paints, New Grades Carbon Black Powder-Beilum Carbon

 Polyurethane Paint is a relatively common type of coating at present, which can be divided into two-component polyurethane coatings and one-component polyurethane coatings. Different pigments give paints different colors, and black paint mainly uses Pigment carbon black as the main pigment.

Pigment Carbon Black makes the coating film appear colorful, and makes the coating film have the ability to cover the object to be coated, so as to play its role of decoration and protection.

At the same time, it can also provide properties such as: improving the mechanical properties of the paint film, improving the durability of the paint film, providing anti-corrosion, electrical conductivity, flame retardant and other properties.

For the two-component polyurethane paint, one component is the curing agent. If you shake the tin can vigorously, you should feel that the paint is shaking, which proves that the curing agent is basically intact. In addition, look at the shelf life of the curing agent, which is generally 6 to 12 months.

The paint film has strong adhesion. Polyurethanes, like epoxies, formulate into excellent adhesives. Therefore, the coating film has excellent adhesion to various surfaces (metal, wood, rubber, concrete, some plastics, etc.).

What is the reinforcing mechanism of Carbon Black? Best price of Beilum Carbon Black in China

  The reinforcing effect of carbon black is mainly that the addition of carbon black changes the structure of the rubber and produces a C-phase structure. In vulcanized rubber, if the carbon black is well dispersed, and a C-phase structure is formed on the surface of each carbon black particle , Phase C plays a skeleton role to connect phase A and phase B. Forming an overall network of rubber macromolecules and fillers, changing the structure of the vulcanized rubber, thus improving the physical and mechanical properties of the vulcanized rubber. Reinforcement mechanism of  carbon black  Surface adsorption layer theory This theory believes that Black carbon and rubber generate a microscopic multi-phase inhomogeneous structure, which is a reinforcing mechanism of composite materials. Nuclear magnetic resonance studies have confirmed that there is an adsorption layer composed of two types of rubber macromolecules on the surface of carbon black. The inner layer of about 0.5nm close to the

What index of conductive carbon black has good electrical conductivity? - Beilum Carbon

  Judging the conductivity of  conductive carbon black  through the oil absorption value index Oil absorption value (DBP) is commonly used to express structural properties. The greater the DBP value, the higher the structural properties. The physical properties and conductivity of conductive carbon black depend on the volume and microporosity of these aggregates. The greater the oil absorption value of  conductive carbon black  DBP, the easier it is to form aggregates with a large number of particles and complex structures, and the more aggregates there are per unit mass. Therefore, under certain conditions, the greater the DBP oil absorption of carbon black, the stronger its conductivity. Based on the particles that make up the basic aggregates and morphology of carbon black, high-structured carbon black aggregates have large, polymeric particles. This branching increases the contact between aggregates, which can lead to high conductive properties. Judging the conductivity of carbon b
