Viscosity Sensor so The Measurement Characteristics

Control is a large challenge for all surface coating viscosity control operations. Many factors affect closing film properties, viscosity coating materials is very important for consistency. Coating viscosity is proportional to coating solids concentration of the liquid film thickness and uniform.

Incorrect film thickness at the excellence of the final product unsuitable, inappropriate, video, a further characteristics. Scrap reduced yields, without the expensive coating material and environmental expenses related to production losses. Periodic manual control with the viscosity increases labor costs and considering the variance of the operator. And plant performance, changes in temperature, the coating material blending options and the process of evaporation is often driven by off-line measurements are unlikely. viscosity coating

A typical coating system include: the unbooked time of base stock and a liquid, the mixture agitated tank, pump, heater, filter, power line, the applicator, the applicator itself, and return mixture of reservoir. Applicator can be used for a dip, roll, spray, sputter, a different processes. To accurately and reliably control the coating viscosity, viscosity at Cambridge recommends best practitioners.

First Use of closed-loop control. Locate a viscosity sensor, therefore it is a substance to get actually applicable for measuring the final product. The number 1 place in the supply line of the applicator. Sensor information should be fed directly to electronics, which controls without make-up liquid or solvent. The integrated PID controller provides excellent performance. An individual gauge of basic shares without filling system.

The second Temperature-compensated viscosity is very important. Temperature has a significant effect on viscosity, but not at all times the surface concentration. Unfortunately, the production of the ambient temperature is often not well controlled. Viscosity and thus free hard in order to be fair, regardless of temperature. Coating has to repeat the temperature-viscosity relationship that can be simply modeled mathematically, that can be directly programmed electronic temperature compensation for accurate viscosity viscosity control regarding temperature changes.

The third Offline measurements are important, but must be strictly controlled. Off-line measurements are often coater control viscosity standard. Unfortunately, usually are very well significant errors from different sources. These off-line measurements can be within a production environment, mugs and more sophisticated laboratory resources. It is important that:

a) The sample includes a coating, and also typical, a lot more places.

b) must be done often enough styles.

c) the shear type of the conditions to be duplicated in the laboratory.

d) sampled and measured, for example, that no off-gassing coating is made way for.

e) All tests must be handled consistently deny the inherent variability of the operator.

4) Automated line viscosity control eliminates errors. Sampling and laboratory methods for diversity very best controlled through an automated line measurement and control. The sensor can be arranged in a manner that measures coating liquid, which is representative with the fluid is applied. Solvent or liquid makeup can be automatically furthered the associated with a magnetic fluid coating consistency. Most of the liquid fluid is pumped and piped fluid shear most on the controls. Achieve a consistent shear sensor is mounted globe supply line applicator. In this particular way, the operator-induced errors in a minimum accurate and repeatable information.

5) small-sized sensors which usually suitable for hazardous area installation and maintenance more uncomplicated. Compact sensor, it is easier to set up and to maintain. If the sample conditioning is necessary, small sensors require smaller amounts of fluid therapy. Self-cleaning/low surveillance sensors are available online or tank configurations.
