Fineness Reduced by 66%! ZYE ZYTR-80E-Plus Roll Mill Machine Solves Silicone Rubber Adhesive Dispersion Challenges
With the rapid development of new materials and precision manufacturing, silicone rubber adhesives are increasingly widely used in electronic packaging, automotive manufacturing, and new energy fields due to their excellent weather resistance, electrical insulation, and flexibility.
In the production of silicone rubber adhesives, because the material system is complex and highly viscous, fillers and additives inside are prone to agglomeration. Uneven dispersion not only reduces the rheological properties of the adhesive and makes extrusion difficult, but also affects its mechanical strength and adhesion after curing. Therefore, how to break up agglomerates through an efficient grinding process and achieve fine dispersion and homogenization of materials is a key step in improving adhesive quality.
Solution
Targeted Breakthrough: Improving Dispersion Uniformity of Silicone Rubber Adhesive
To solve the problem of particle agglomeration inside the material, a materials company in Guangdong partnered with ZYE Technology to conduct a fine dispersion experiment on silicone rubber adhesive. This experiment was designed to use a roller mill grinding process to achieve more uniform dispersion of high-viscosity materials and strict fineness control.
Experiment Process
Customer Name: A materials company in Guangdong
Experimental Material: Silicone rubber adhesive
Experimental Equipment: ZYE Technology ZYTR-80E-Plus roll mill machine + laser particle size analyzer
Experimental Objective: To achieve more uniform material dispersion through roll mill grinding and reduce fineness to below 10 microns.
Experimental Steps: Scientific Three-Stage Dispersion Process for Silicone Rubber Adhesive with a Roll Mill
1. Initial Testing: Obvious Large-Particle Agglomeration in the Material
Before the experiment, the untreated silicone rubber adhesive was initially tested using a laser particle size analyzer. The data showed that relatively large particles existed inside the material, requiring fine grinding.
Initial particle size data: D10 = 4.139 μm, D50 = 18.64 μm, D90 = 59.26 μm.

2. Three-Stage Dispersion Process: Precise Control of Roll Gap and Pressure
In view of the high viscosity of the silicone rubber adhesive, the experiment used the ZYTR-80E-Plus roll mill machine to disperse and homogenize the slurry through a set three-stage dispersion process, ensuring that the particle size was stably controlled below 10 μm and significantly improving the rheological properties of the slurry. The specific process parameters were as follows:
Coarse mixing stage: Roll gap set at 10–5 μm to initially break up large-particle agglomerates.
First fine grinding: Roll gap set at 1–1 μm to further refine the particle size.
Second fine grinding: Inter-roll pressure set at 2–1 N/mm to complete final homogeneous dispersion.
Throughout the operation of the roller mill, the equipment performed stably, discharged evenly without material leakage, and the slurry condition was significantly improved.

3. Discharge Testing: Fineness Successfully Reduced Below 10 μm
After three-stage grinding by the ZYTR-80E-Plus, the laser particle size analyzer was used again for testing. The data showed that the fineness of the slurry was greatly optimized, reaching the expected experimental target.
Discharge particle size data: D50 = 6.119 μm.

Result Analysis: 66% Reduction in Fineness, Significant Process Advantages
Combined with the test report from the laser particle size analyzer, this experiment achieved significant dispersion results:
1. Core breakthrough in fineness
After using ZYE Technology’s ZYTR-80E-Plus three roll mill, the median particle size (D50) of the material decreased significantly from the initial 18.64 μm to 6.119 μm, a reduction of 66%. This indicates that the shear force applied by the equipment effectively broke the agglomerated structure inside the adhesive and achieved a high degree of homogenization.

2. Comparison of equipment and process advantages
Compared with traditional three-roll mills, the ZYTR-80E-Plus demonstrates superior dispersion precision and consistency when processing high-viscosity silicone rubber adhesive. From the final particle size distribution curve, it can be seen that the particle size distribution of the material ground by Zhongyi equipment is narrower and more concentrated, effectively avoiding batch-to-batch variation caused by uneven grinding force in traditional equipment.

Conclusion
The laboratory data objectively verifies that ZYE ZYTR-80E-Plus three-roll mill, with its precise roll gap and pressure control capabilities, can efficiently solve the dispersion problems of silicone rubber adhesive during production. Its stable three-stage dispersion process not only successfully controls material fineness below 10 μm, but also greatly improves material homogeneity and rheological properties, providing reliable equipment support for the R&D and mass production of high-quality adhesives.
