Carbon black, a special pigment for jointing agents, is a necessary chemical raw material for jointing agents
Jul 28, 2023
In the construction industry and some construction areas, some gaps often appear, and a pointing agent is used. The pointing agent is usually used as cement, but it is often necessary to add the pigment carbon black to the cement to give it more color and enhance its strength. The pigment carbon black can quickly absorb carbon dioxide in the air, making the cement oxidize and firm after application.
Application Instructions for Carbon Black, a Special Pigment for Pointing Agents:
Carbon black, a special pigment for pointing agents, is developed for building materials to overcome customer requirements for high blackness, strong coloring power, long-term non deterioration, water resistance, and good dispersion performance. This requires processing the produced carbon black to ensure it has good adhesion and can be firmly adsorbed on the surface of cement, without fading after prolonged water flushing.
The special pigment carbon black for jointing agent can be widely used in jointing agent, decorative building brick, tactile paving brick, European brick, European cable brick, grass planting brick, curbstone, Concrete masonry unit, tree pool, hollow block, black cement and other products, with the characteristics of less addition and strong covering ability.
Requirements for selecting pigment carbon black for jointing agent:
The specific ratio of carbon black pointing agent is related to the type of carbon black used and the desired effect. The pointing agent used and the pigment carbon black selected are different, and the amount added is also different. If the requirement is not met and the black spot is desired, high pigment carbon black can be selected or the amount added can be increased. Those that have already met the requirements can save costs by selecting lower grade carbon black or reducing the amount added. The general addition amount is between 1% -3%.
