In water-based systems, particle agglomeration, uneven dispersion, and poor long-term stability are common challenges facing many enterprises. These problems can lead to uneven color, reduced performance, or lower production efficiency.
Chemi Tech focuses on the R&D and innovation of water-based dispersants, offering customized solutions tailored to the characteristics of different materials. Our technical team helps customers achieve efficient dispersion through the following steps:
Step one: analyze material characteristics and process conditions. Key parameters such as particle size, surface charge, and system pH are determined through laboratory testing.
Step two: match the dispersant type and dosage. Choose an anionic, nonionic, or composite dispersant to ensure system compatibility and optimize the addition ratio.
Step three: optimize dispersion process parameters. Adjust stirring speed, temperature, and addition sequence to maximize dispersion efficiency.
Step four: verify stability and performance. Confirm the effectiveness of the solution through centrifuge testing, storage-stability testing, and application-performance evaluation.
One coating enterprise using a general-purpose dispersant encountered pigment settling and insufficient gloss. Chemi Tech recommended a high-molecular-weight polycarboxylate dispersant at a dosage of 0.8% and optimized the grinding process. After the adjustment, the coating's viscosity stability improved by 40%, color uniformity improved noticeably, and energy costs were reduced.
We emphasize the practicality and operability of technical service, helping enterprises improve product competitiveness from the source.
