In numerous fields such as flame-retardant materials, composite materials, and ceramic building materials, aluminum hydroxide has become an indispensable key raw material due to its outstanding flame-retardant properties, corrosion resistance, and environmental friendliness. In the field of flame retardancy for polymer materials like plastics and rubber, aluminum hydroxide must be uniformly dispersed within the organic matrix to achieve a flame-retardant effect through dehydration and heat absorption at high temperatures, while ensuring that the material’s mechanical properties remain largely unaffected. In the coatings industry, as a bulk pigment, it needs to exhibit excellent dispersibility and adhesion to prevent issues such as sedimentation and delamination. In ceramic production, the surface activity of its particles directly influences the sintering performance of the green body and the density of the finished product.

The coating and modification machine demonstrates its capabilities in alumina hydroxide processing. Two Outstanding application features. First, it boasts high coating uniformity; the equipment employs multiple sets of rotors. The stator structure is designed to ensure that powder particles achieve 360° collision and friction with no dead angles within the modification chamber, enabling a coating rate of the modifying agent as high as 9%. 9.2 Moreover, this process effectively avoids performance fluctuations caused by insufficient local coating in traditional methods. Second, the process boasts strong controllability: a PLC control system allows for precise adjustment of key parameters such as modification temperature, rotor speed, and modifier dosage. This enables rapid switching between different process configurations tailored to specific application scenarios—for instance, high-hydrophobic modification is required for flame-retardant plastics, while high-dispersibility modification is needed for coatings—resulting in a stable product qualification rate consistently above 99%.

The precise processing of the coating and modification machine directly imparts a series of core performance advantages to aluminum hydroxide materials, fully unlocking their value across various application fields. In the flame-retardant sector, aluminum hydroxide that has undergone coating and modification interacts with... The compatibility of plastic matrices such as PP and PE has been significantly enhanced, meeting the flame-retardant rating requirements of industries including construction and home appliances. In the coatings industry, the dispersibility of the modified aluminum hydroxide powder has been greatly improved, while its anti-aging performance has also been markedly strengthened.

Whether it’s enhancing the safety performance of flame-retardant materials, optimizing the application effects of coatings, or reducing the overall costs of ceramic production, coating modification machines—with their precise process control, stable processing quality, and remarkable performance improvement effects—have become indispensable key equipment for alumina hydroxide processing enterprises.
