BONDING means adhesion in English, and “bangding” comes from its transliteration. The bonding techniques of metal powder coatings are to make adhesion of metal pigments and resin powder coatings. The metal bonding powder is a kind of high value-added product, and a coating widely applied in home furnishings, household electrical appliances, architectural ornaments, automobile industry and other industrial products.

Decai’s perfect bonding techniques have become the standard of metal powder coating industry. After unremitting tests and experiments, we have developed the techniques of temperature-sensitive products applicable for specific requirements. Such innovative techniques can ensure that the metal powder coatings do not discolor but keep beautiful and long-lasting, and guarantee the customers having competitive advantages in international markets.

Technique process

The strict control stage of bonding techniques is the temperature segment at which the resin begins to soften and the aluminum powder is bound. At this temperature segment, the resin changes from powder to mass. This temperature segment is very short. If the mixture temperature is higher than this temperature, the mixture will be caked, and cannot be used again. The whole bonding techniques of Decai masterbatch mixing machine can reach the surgical like precision, and ensure absolute reliability of techniques.

Production process

By generating heat through friction, the temperature of the base material mixture is increased, then the aluminum powder is added when the temperature value is slightly lower than the glass transition temperature (TG) of resin. Keep heat preservation for a certain time under this temperature until the aluminum powder and resin are bound completely. The combination of optimization technologies with precision mechanical design is reliable guarantee for reliable operation, no-damage production and excellent product price performances. These characteristics are alsoimportant factors to consider firstly for investment return.

The Decai bonding machine optimizes the production of metal bonding powder. The drive shafts, blades, pot wall interlayer and pot bottom of bonding machine have mutually independent cooling areas. The blades are of integrated design. All basic technique parameters of control device can be stored in the software which is researched and developed wholeheartedly. The organic combination of mechanical design, control hardware and software program have met the complicated techniques and technical control, met the special requirements for temperature-sensitive products, and provided irreplaceable schemes for the production of bright-colored metal bonding powder. The downstream cooling mixing machine can cool the bound metal bonding powder timely, and prevent caking of raw materials. The cooling mixing machine of appropriate size can also homogenize several batches of materials in the binding machine. The metal bonding powder produced by Decai bonding machine does not have separation characteristics but has constant colors, thus provides advantageous conditions for the market comp
