The occurrence of "agglomeration," "cohesion," and "viscosity increase" in dispersion processes is caused not by the equipment but by the design of the process. Poor wetting during powder input and unsuitable dispersion conditions lead to quality variations and poor redispersion, significantly compromising stability during mass production. Additionally, during scale-up, it is often impossible to reproduce the same conditions, resulting in unexpected troubles. Furthermore, every time there is a change in materials or formulations, new conditions must be established, increasing the burden of development and mass production. Shibuya Kogyo's solid-liquid mixing and dispersion system is designed to provide a consistent process from powder supply to dispersion, formulation, and CIP cleaning. By optimizing the entire process, including material properties, input conditions, and fluid design, we stabilize dispersion quality and reproducibility. Moreover, optimization across the entire line contributes to reducing losses between processes and lowering equipment load. It is not just a dispersion machine but a dispersion system that governs the entire process. By building quality from the design stage, we achieve shorter startup times and improved yields. We also provide consistent support from equipment selection to startup, reducing the burden on the site. We propose the optimal dispersion process tailored to your materials and process conditions. Please consult us about your current challenges. We support you from initial considerations to mass production startup.

In the manufacturing of battery material slurries, dispersion quality is a crucial factor that influences product performance. However, in high-concentration slurries, challenges such as the formation of clumps during powder addition, aggregation of nanoparticles, and decreased fluidity due to increased viscosity can arise, leading to quality variations and reduced productivity. Additionally, during scale-up, it can be difficult to reproduce conditions, which may lead to issues in mass production. Our inline solid-liquid mixing and dispersion system is designed for a seamless process from powder supply to dispersion, formulation, and CIP cleaning. By optimizing the entire process, including material properties, input conditions, and fluid design, we stabilize dispersion quality and reproducibility. In battery materials, frequent changes in formulation and material lot differences often require resetting conditions, making it challenging to maintain a stable dispersion state. Our system optimizes dispersion conditions throughout the entire process, flexibly responding to these variable factors and achieving quality stability and improved reproducibility. Not just a simple dispersion device, but a dispersion system that governs the entire process, it is capable of supporting everything from the development stage of battery materials to mass production lines. For those struggling with clumps, aggregation, and viscosity increases in battery material slurries, we propose the optimal dispersion process tailored to material characteristics and process conditions. Please consult us about your current challenges.

In the manufacturing of resin materials, dispersion quality affects product performance and appearance quality. Particularly in formulations containing fillers, dispersion unevenness and agglomeration are likely to occur, leading to issues with strength, functional characteristics, and appearance defects. Additionally, in high-viscosity systems, poor mixing and viscosity variations can easily arise, making it challenging to ensure quality. Furthermore, during scale-up, reproducing dispersion conditions can be difficult, resulting in cases where quality is not stable during mass production.

Cellulose nanofiber (CNF) is being utilized in a wide range of fields such as automotive, food, and cosmetics as a next-generation material with high strength and lightweight properties. However, CNF has strong cohesiveness and high viscosity, which can lead to challenges such as "clumping," "poor dispersion," and "mixing issues due to increased viscosity," making stable dispersion difficult. In particular, poor wetting during powder addition and incompatibility in shear conditions and fluid design can easily lead to variations in dispersion quality and reduced reproducibility, often resulting in cases where consistent quality cannot be reproduced during scale-up. Shibuya Kogyo's solid-liquid mixing and dispersion system optimizes the entire process, including powder supply, addition conditions, dispersion processes, and fluid design, according to the characteristics of CNF. This is not just about selecting equipment; it achieves stabilization of dispersion quality and improvement of reproducibility from a process design perspective. Furthermore, by designing the entire process consistently from dispersion to formulation and CIP cleaning, it also contributes to reducing losses between processes and lowering equipment load. With consistent support from research and development to mass production startup, we assist in solving the challenges of the CNF dispersion process.

In the dispersion process of battery slurry, it is often observed that while dispersion can be achieved without issues during the research phase, it cannot be replicated during mass production, leading to quality problems. This is particularly true for positive and negative electrode slurries and CNT conductive materials, where variations in powder input conditions, dispersion energy, viscosity changes, and differences in process configuration can significantly alter the dispersion state and coating properties. Our service conducts dispersion tests at the lab scale based on the customer's materials and formulation conditions, evaluating the dispersion state, viscosity characteristics, and reproducibility. Furthermore, we support scale-up verification using small machines and pilot equipment, visualizing risks during mass production in advance. This is not just a simple test; through verification that delves into process design, we assist in reducing troubles during the transition to mass production and shortening the startup period.

Negative electrode slurry (graphite, Si-based) tends to have high solid content and high viscosity, making it a challenging material for mixing and dispersion. Issues such as clumping during powder addition, poor binder dispersion, mixing failures due to increased viscosity, and variations in coating properties are common, especially with Si-based materials, where the dispersion state directly affects battery performance and lifespan. Additionally, there are many cases where dispersion can be achieved in the research phase but cannot be reproduced during mass production. This system is designed to optimize the entire process from powder supply to dispersion and formulation, optimizing input conditions, dispersion energy, and fluid design. It achieves uniform dispersion even under high viscosity conditions and ensures reproducibility through consistent scale-up design from the lab to mass production. We propose the optimal process tailored to material properties and formulation conditions.

In conductive paste using CNT (carbon nanotubes), the strength of aggregation and the difficulty of dispersion are challenges. If not sufficiently dispersed, a conductive network will not form, leading to unstable performance; on the other hand, excessive shear can lead to the destruction of the CNT structure, making the optimization of dispersion conditions essential. Furthermore, even slight differences in the dispersion state can significantly affect viscosity and conductivity, becoming a factor in quality variation during mass production. This system appropriately breaks down CNT aggregation while maintaining structure through process design that includes powder input, wetting processes, dispersion energy control, and circulation conditions. It is designed with the same logic from the lab to mass production, achieving a balance between conductivity and reproducibility.

In the manufacturing of lithium-ion batteries (LiB), the dispersion quality of the positive and negative electrode slurries and conductive material pastes significantly affects battery performance, lifespan, and safety. On-site challenges include clumping during powder input, agglomeration of conductive materials, poor mixing due to increased viscosity, and variability between batches. Particularly in the research phase, issues may not arise, but many cases are observed where they cannot be replicated during mass production. Many of these challenges stem not from individual equipment but from the entire process, including input conditions, dispersion energy, fluid design, and process configuration. This system is designed to provide a consistent approach from powder supply to dispersion and formulation, establishing an optimal dispersion process tailored to material properties and formulation conditions. By designing with the same logic from the lab to small machines, pilot, and mass production lines, reproducibility and quality stability during scale-up are achieved. It is also capable of accommodating process design according to the characteristics of the positive electrode, negative electrode, and conductive materials.

The quality of protein products is greatly influenced by their dispersion state. In particular, powdered protein often faces challenges such as clumping during dissolution in water or solvents, uneven dispersion, and poor mouthfeel. Additionally, changes in formulation or raw materials can alter viscosity and dispersibility, leading to cases where there are no issues during prototyping but quality becomes unstable during mass production. This service conducts dispersion tests tailored to raw material characteristics and formulation conditions, verifying the suppression of clumping, improvement of dispersibility, and enhancement of mouthfeel. Furthermore, through process design aimed at scaling up from the lab to small machines and mass production equipment, we establish reproducible manufacturing conditions. We can support evaluations from the prototyping stage to pre-mass production verification.

In the dispersion process of resin materials, the dispersion state of fillers and additives greatly influences product performance. Issues such as strength reduction due to poor dispersion, appearance defects, variability in functional characteristics, and viscosity fluctuations are likely to occur, especially in high-fill and nano-filler systems where dispersion difficulty increases. Additionally, even if there are no problems during the prototype stage, it is often seen that the same quality cannot be reproduced during mass production. This service conducts dispersion tests tailored to material properties and formulation conditions, evaluating dispersion state, viscosity characteristics, and reproducibility. Furthermore, through scale-up verification using small machines and pilot equipment, risks during the transition to mass production are visualized in advance. This is not just a simple test; by delving into process design, we support quality stability and productivity improvement.

The performance of adhesives greatly depends on the dispersion state of fillers and additives, and even slight differences in dispersion can affect adhesion strength, durability, and appearance quality. Particularly in highly filled systems, issues such as clumping, undispersed particles, and poor mixing due to viscosity increases are likely to occur, leading to variations in dispersion and quality due to sedimentation and separation. These challenges often stem not from the equipment alone but from input conditions, dispersion conditions, and process composition, manifesting as problems that cannot be reproduced during mass production. In this service, we conduct dispersion tests based on the customer's materials and formulation conditions to evaluate the dispersion state, viscosity characteristics, and their impact on adhesive performance. Furthermore, we perform scale-up verification using small machines and pilot equipment to clarify the reproducible conditions for mass production. By conducting thorough verification that delves into process design, we support quality stability and reduction of development time.

In the positive electrode slurry of lithium-ion batteries, the ability to uniformly disperse active materials, conductive agents, and binders affects the coating properties, electrode quality, and stability of battery performance. In actual production environments, issues such as clumping during powder addition, aggregation of conductive materials, poor mixing due to increased viscosity, and variations in dispersion between batches often arise. Even if there are no problems during the research phase, it is not uncommon for these issues to hinder reproducibility in mass production. This system designs the entire process of positive electrode slurry, including powder supply, input conditions, dispersion energy, circulation conditions, and formulation processes, to suppress dispersion inconsistencies and undispersed materials. By focusing on process design rather than just the equipment itself, it supports consistent scale-up and reproducibility from laboratory validation to mass production lines. It is also possible to consider conditions tailored to the positive electrode materials and formulation conditions.

In the production of CNT water dispersion, it is important not only to break down agglomerates but also to maintain a dispersed state. CNTs tend to agglomerate strongly at the nanoscale, and even after dispersion, re-agglomeration can occur, making stable quality assurance a challenge. This system consistently controls the process from dispersion to stabilization through inline continuous operation. It maintains a uniform dispersion state while suppressing excessive shear, preventing re-agglomeration. It accommodates water-based and low to medium viscosity conditions, contributing to the stabilization of CNT dispersion quality and improving reproducibility in mass production processes. Furthermore, by optimizing dispersion conditions and residence time, it is possible to suppress variations in the dispersion state and continuously ensure stable quality. It also supports consistent scale-up design from the lab to mass production, aiding in the stable manufacturing of CNT dispersion.
