• Bridge Materials

Fine abrasive particles, such as precision grinding agents, may physically aggregate in water due to intermolecular forces and charging effects. This aggregation can lead to the formation of coarse abrasive particles, which may cause scratches, scuffs, and changes in concentration. To prevent this physical aggregation, one method is to coat each particle (abrasive grain) to inhibit physical aggregation between particles. Coating can improve the dispersion of slurries by suppressing the aggregation and adhesion between particles. We encourage you to try the additive "EVERFLO," which can enhance and improve grinding performance simply by mixing it into your grinding slurry. Expected effects from the addition of EVERFLO: - Improved dispersion - Suppression of scratches and scuffs - Increased lifespan (stabilization of grinding capability) - Enhanced cleanability *Note*: When used in silica slurry, there is a possibility of gelation, so please confirm in advance whether gelation will occur.

However, whether treatment is possible depends on factors such as particle size, so it cannot be said that any material can be treated. The treatment situation also varies depending on the type of coagulant. Here is a guide on how to confirm whether treatment is possible. 1. Check the original particle size If it is around 80 nm, there is a possibility of treatment. If it becomes finer than that, treatment becomes significantly more difficult. 2. Confirm the coagulation effect First, check the effect as it is. If treatment is possible, that’s fine; if it’s difficult, move on to the next step. 3. Dilution Dilute while the coagulant is added. Check the effect while performing dilution and adding the coagulant. Dilute boldly to about 5 to 10 times and confirm at what dilution there is an effect. The alkalinity of colloidal silica wastewater can interfere with coagulation treatment, so it is also important to start with neutralization treatment in such cases. After neutralization treatment with sulfuric acid bands, coagulation treatment may significantly reduce the amount of coagulant used. First, please check the effect with a free sample or consider our free wastewater treatment test.

The effects obtained by incorporating "groove processing (pitch)" into the grinding pad are as follows: - It allows the grinding slurry to reach the inner circumference of the grinding machine, achieving uniform grinding. - It leads to an improvement in the grinding rate. - The discharge of grinding debris (such as sludge) becomes smoother. - By changing the pitch width on the upper and lower plates, it reduces the suction phenomenon of the substrate and workpiece. Regarding the groove specifications, you can specify the groove width, pitch width, depth, and type (concave, U-shaped), according to your preferences. *The basic groove type is "grid-shaped grooves," but other embossing processes can be discussed. Additionally, "drilling of abrasive particle holes" is also possible upon request. This can help with cumbersome tasks on-site and contribute to safety management. *For more details, please feel free to contact us.

I will explain the usage points of the alkaline type "Mizusumairu," which can treat wastewater that has come into contact with strong alkaline substances such as concrete slurry and tool washing water, based on my previous experience. Point 1 - Stir well The powder coagulant is most effective when stirred well. Please note that the recommended stirring method varies depending on the amount of water to be treated. Manual treatment... Stirring machine, Notch tank treatment... Submersible pump Point 2 - Be careful not to add too much. The alkaline type "Mizusumairu" can neutralize and coagulate with one agent, but adding too much can make the treated water acidic, so please add it while checking the pH value. * Please refer to the guideline for the amount to be added. * pH checks should be done using a pH meter or pH test strips. Point 3 - Please dilute if the moisture content is low. If the moisture content of the target water is low (for example, if it is very dirty and thick), treatment may not proceed, so please dilute with water to ensure sufficient moisture content. By paying attention to these points, you can achieve better treatment results.

• Turbid water and muddy water treatment machines

"Water Clear (Alkaline Type)" is a powdered coagulant that can perform neutralization and coagulation treatment in one step. Water used to wash tools made with cement and mortar shows strong alkalinity and contains residues of cement and mortar. Typically, neutralization and coagulation treatments are carried out separately, but for wash water of about several tens of liters, neutralization is a very delicate and difficult process. In such cases, "Water Clear (Alkaline Type)," which can complete both neutralization and coagulation with a single agent, is recommended.

• Water Treatment

"Oil Flock" is a powdered coagulant that can treat wastewater from cerium oxide polishing. There are times when several tens of liters of difficult-to-treat polishing wastewater accumulate, such as when testing is done sporadically. In such cases, performing coagulation treatment for each batch of polishing wastewater can reduce the burden on treatment facilities and lead to cost savings. Oil Flock is a powdered coagulant that can remove up to 99% of suspended solids (SS), with minimal pH fluctuations before and after treatment, making it very user-friendly.

• Water Treatment

Coagulants used in construction and civil engineering can sometimes be applied to other purposes. Here are some examples where coagulants can be used effectively. For instance, wastewater generated in facilities such as chemical manufacturing and food processing contains various solids and organic materials. By adding coagulants, it is possible to aggregate the fine suspended particles in this wastewater and improve water quality. Additionally, for the purification of ponds and lakes, coagulants can be used to aggregate suspended solids and organic materials within the water body, leading to improved clarity and cleanliness of the water. [Examples] ■ Industrial wastewater treatment ■ Purification of ponds and lakes *For more details, please feel free to contact us.

• Drainage and water removal

Here, we will introduce key points for effectively using powder coagulating agents. Phenomena such as "no coagulation despite adding coagulating agents," "treated water becoming cloudy," and "dirty water becoming clear but viscous" can be caused by insufficient stirring or excessive addition of coagulating agents. The key points for using powder coagulating agents are that "the target water (turbid water) should be neutral" and "it should be stirred well." 【Testing Method for Coagulating Agent Samples】 ■1. Addition ■2. Strong shaking ■3. Gentle shaking ■4. Separation *For more details, please feel free to contact us.

• Turbid water and muddy water treatment machines

We would like to introduce "Mizusumairu (Alkaline Type)," which can treat concrete wastewater and mortar wastewater that have come into contact with strong alkalis with a single agent. At construction and civil engineering sites, cement-related wastewater is often treated on-site using methods such as "neutralization treatment" or "coagulation sedimentation treatment." However, neutralization treatment often involves the use of hazardous chemicals and requires careful management of precise additive amounts. By using this product, it is possible to streamline these processes. 【Features】 - Can treat concrete wastewater and mortar wastewater that have come into contact with strong alkalis with a single agent. - Can perform neutralization treatment and coagulation treatment simultaneously. *For more details, please feel free to contact us.

Do you know the suitable particle size for dressers for urethane pads? How to finish the PAD surface with a dresser is indeed important for improving quality and yield. In practice, incorporating multiple processes solely into the dresser can be inefficient on the manufacturing floor, and it may lead to an increase in man-hours and costs. Therefore, we introduce dressers by selecting a "best of both worlds" particle size. The suitable particle size varies depending on the processing environment, so please feel free to consult us about the appropriate dresser and particle size for your current processing environment. [Purpose of the dresser] - Elimination of clogging and flattening - Precision correction - Smoothing the PAD surface, etc. *For more details, please feel free to contact us.

When polishing with polyurethane pads using cerium oxide and other materials, abrasives inevitably remain in gaps and holes. The efficiency of the next polishing operation greatly depends on how well the abrasives are removed during the cleaning at the end of the workday. However, doing this manually can lead to uneven cleaning, and if this accumulates, it poses a risk of shortening the lifespan of the polishing pads. Therefore, we recommend using a brush carrier. Please feel free to contact us to see if it can be adapted to your work environment for improved quality. 【Benefits of the Brush Carrier】 ■ Other tasks can be performed while cleaning the brush ■ Reduced likelihood of rate decrease due to pad clogging ■ Polishing quality has stabilized, leading to improved yield *For more details, please feel free to contact us.

In flat grinding, it may be natural to perform maintenance on the PAD using a dresser, but surprisingly few places actually measure and manage it to the extent of numerical values. Due to the characteristics of grinding, there is a tendency for the central area of the reference plate to become more concave, but simply making corrections at regular intervals and for the same duration does not truly indicate whether proper maintenance is being conducted. Therefore, by using a straight gauge, it becomes possible to manage the numerical values of the overall shape, making production management very efficient. 【Precision Management Method】 ■1. Establish the reference for the straight gauge (dial gauge) ■2. Measure the reference plate (When measuring the reference plate, use a base set if measuring soft materials) *For more details, please feel free to contact us.

In wastewater treatment involving cerium oxide (ceria) and zirconium oxide (zirconia), there are cases where coagulation treatment using polymeric coagulants does not work well due to differences in the inflow concentration of abrasives. This is often not due to the capability of the polymeric coagulants, but rather due to insufficient neutralization treatment or primary treatment, which is an area that requires countermeasures. The "De-Silt Tablet" is a solid coagulant that can achieve sufficient coagulation effects on its own, but it also serves as an auxiliary agent in cases like the ones mentioned above. 【Features】 ■ Treatment is possible with just one agent ■ No need to adjust the amount added (just soak) ■ Can be used both as an auxiliary agent and as a coagulation treatment agent ■ Can also be used as a sedimentation promoter, making it more effective when longer sedimentation times can be taken *For more details, please feel free to contact us.

The "Oil Flock" we handle is a powdered coagulant that can treat wastewater containing black smoke. Wastewater containing black smoke can appear pitch black and be difficult to process depending on its concentration, but once it is understood that it can be treated with a coagulant, it is possible to effectively treat it simply by adjusting the amount added. While testing of the treated water is necessary, if the quality of the treated water meets the discharge standards of each municipality, only the coagulated material needs to be disposed of, and the treated water can be discharged. [Features] - Treatment is possible with just one agent - The viscosity of the coagulated material is low and has good dewatering properties - Coagulation and sedimentation can occur in a short time - The coagulated material is of a certain size, making it easy to recover *For more details, please feel free to contact us.

• Drainage and water removal

The occurrence of crashes due to pads peeling off or misaligning during polishing not only leads to damage to the substrate and the need for pad replacement but also requires cleaning of the polishing machine and removal of debris, resulting in a significant decrease in work efficiency. This issue can be resolved by using tape with strong adhesive properties; however, a disadvantage is that it can be difficult to remove the pads. Therefore, the choice of double-sided tape may vary depending on the customer's objectives, applications, and priorities. At FILWEL, we mainly offer tapes from three manufacturers. We can also prepare options beyond these three types according to the customer's needs, so please feel free to consult with us. *For more details, please do not hesitate to contact us.*

Would you like to try groove processing on suede pads? I believe suede pads are typically used in the final stages of polishing. Therefore, the finish of the polished surface is important, but depending on the workpiece, there may be differences between the upper and lower polishing surfaces. While this is not always the case, there can be instances where the polishing liquid does not fully drain on the lower side. By performing groove processing on the lower pad, the polishing liquid can be evenly distributed. Additionally, if the workpiece is thin and light, there can be a phenomenon where it sticks to the upper side. This can be mitigated by performing groove processing on the upper pad. We also offer U-shaped grooves in addition to the standard rectangular shape, and by making the edges of the grooves obtuse, we can reduce surface defects. Furthermore, since the flow rate of the polishing liquid increases, uniform polishing can be achieved, leading to improved accuracy. 【Features】 ■ Groove shapes: rectangular, U-shaped ■ Reduces surface defects ■ Improves accuracy *For more details, please feel free to contact us.
