PVB Plastic Pellet Moisture
PVB, or polyvinyl butyral, is an 80-year-old resin used for strong binding applications that need:
The most common application is laminated safety glass in car windshields, although they are also used in ceramic adhesives, inks, paints and coatings, binders for magnetic media, and adhesives for metals. Scrap from PBV applications is collected and made into pellets for recycling into polymer blends. It is also used as a coating material.
As with any textile manufacturing process, controlling PBV plastic pellet moisture during production is critical to the product’s final quality. By measuring the moisture, the producer can ensure the quality of the end product and sell it at the appropriate price. The cost of the product is usually calculated based on the weight of the pellets, and the moisture affects this.
The moisture content varies a lot between raw materials and at different points in the manufacturing process. A moisture measurement system is critical that can:
MoistTech has been controlling moisture in manufacturing environments for more than 40 years. Our skilled engineers, along with industry partners, have devised a new, advanced NIR sensor, the IR-3000 to monitor moisture, as well as take temperature readings and film thickness ones, continuously from above the conveyor belt. When the moisture is out of preset bounds, you are alerted, so that corrective action can be taken. Our sensor is pre-calibrated at the factory and requires no calibration maintenance.
Typical moisture accuracy is about ± 0.05%, with coating accuracy varying from 0.1 to 0.01 micron, depending on the coating type. A typical analog range is 0-10% moisture. The outputs can be adjusted to optimize recording requirements or PLC.
At MoistTech, we have established the most extensive user base in the moisture management industry. Our IR-3000 is the most accurate, most reliable, and the most technologically advanced system available. Go with the leader, and contact us today for more information about using the IR-3000 for your application.
