Processes The LiquiSonic® analyzer allows a continuous monitoring of cleaning, degreasing, quenching, rinsing and treatment baths in all common industrial surface treatment and cleaning processes. Spray or immersion baths are used to remove film-type or particulate soiling from components. In baths for surface treatment, for example, anti-corrosion coatings are applied or surfaces are being densified or hardened by active substances. Technologically, these processes are implemented in single baths or cascades. The graphic below shows an example of using the LiquiSonic® bath monitor in process....

During the mixing of bath chemicals from supplied concentrates and the solvent (e.g. water), dilution control for target concentration is necessary as it ensures an efficient use of the materials used with consistent implementation of quality-related parameters. The dilution control can also be done directly in the bath in a separate storage tank. Process documentation is particularly important to have a proof of compliance with the quality related parameters „bath concentration" and „bath temperature" within the process chain. The information on bath concentration is used to redose the cleaning...

ApplicationsAutomotive and aircraft In order to meet the cleanliness requirements of specific components and to ensure long-term reliability, impurities such as oil and mineral deposits are removed from finished components. Otherwise damages of the components arise, once they are used under extreme loads. At high cleaning volumes, components are purified with aqueous cleaners such as Hakupur that consists of inorganic ingredients (builder) and tensides. These cleaners can remove oily ingredients well and disperse in the cleaning liquid. For components with a complex geometry and very high cleaning...

In the metalworking industry, different cleaning products are used depending on the cleaning method and surface contamination. These cleaning products usually consist of different components such as tensides and complexing agents, which have a high cleaning power in combination. Only the continuous concentration monitoring of these cleaners ensures a consistently good cleaning result. Depending on the material of the components, cleaning baths with aqueous or nonaqueous cleaners are used. Different baths are combined in order to achieve a high level of cleanliness of the components. In order...

Your benefits: Hardening is the process of heating a component to harding temperature of quench and subsequent rapid cooling (quenching). During this process the component‘s structure changes, resulting in a significant increase in hardness. For example, saline solutions or oils are used as quenchant. avoiding incorrect dosages preventing cracking insufficient hardening in case of overdose reproducible results trough constant quenching targeted and efficient process control ensuring optimum hardness of products There is a high correlation between the concentration of the quench liquid and its...

Ensuring an effective and efficient coating by monitoring the concentration and quality of the coating materials requires inline analysis in coating processes with liquid substrates such as adhesion promoters or corrosion protection. A corrosion protection of metallic materials can be ensured through the application of protective agents such as Wigol. These inhibit the formation of rust over several weeks. The temporary protection enables a longer storage of the products between the processing steps. After the coating, another product cleaning is performed in order to remove excess coating material...

In the electronics industry, residues of flux, resin and solder pastes are removed from components and printed circuit boards (PCB) through the use of different types of detergents. Aqueous cleaners, such as Vigon and Atron, have the advantage of a very low VOC content (volatile organic compounds), which means they only have a few volatile components. Furthermore, there are no flash points, so cleaning facilities are not subjected to the requirements of explosion protection. In most cases, aqueous cleaners contain tensides as detergent substances, which assimilate the impurities and capture the...

In the production of plastic components and polymeric intermediates, surface contaminations such as release agents, abrasion and dust are removed in order to further process the components in subsequent processes. These include, for example, gluing, coating or painting. For other products, monomers, inhibitors and other additives must be removed from polymer. Mostly pure solvents like propanol are used to dissolve residual monomers in an optimal way. Often, different cleaning baths are combined with various solvents to achieve the maximum cleaning effect. In order to avoid transmission rinsing...

LiquiSonic® QC LiquiSonic® QC in the production For processes and systems in which an inline measurement is not feasible and the quality monitoring thus requires sampling, SensoTech has created a clever solution. Especially with small volumes, an inline measurement is often not reasonable and entails expensive conversions. Thus, LiquiSonic® QC, the especially developed central quality test site, is perfectly suitable in such systems. LiquiSonic® QC is adjusted to the individual concentration ratios at the relevant measuring points in the production system. The system can be expanded to include...
