Online Infrared Coating Thickness Measurement System for Epoxy Resin Self-adhesive Adhesive

Interview

Product Detail

Application Background:

The online real-time measurement of the thickness of various films and coatings has always been a difficult problem in the flexible packaging material industry. The company's online infrared coating thickness detection system provides the latest real-time film and coating online detection technology solutions, making the online control of product quality and cost easy and simple.

In addition, the problem of curling and flattening is a very important problem in the label and conversion industry. The non-uniformity of moisture will lead to the shrinkage and expansion of cellulose fiber, crimping will cause difficulties in printing and packaging, and the coating will also appear thicker or thinner at the edge. The near-infrared detector can conduct real-time online horizontal scanning detection of the moisture and coating of materials, It greatly reduces the occurrence of curl and solves the uniformity and consistency of coating, and improves the quality and cost control level of enterprise products.

 

Working Principle:

Molecular bonds, such as O-H bonds in water molecules and C-H bonds in oils and organic coatings, can absorb discrete near-infrared light, and these absorption amounts are in direct proportion to their content. The absorption amount is obtained by comparing the signal of the absorbed wavelength and some non-absorbed wavelength. The near-infrared light of different wavelengths is projected onto the tested material through the near-infrared filter. Each filter generates two internal and external beams. The external beam is collected and projected to the photo-detector through the dome mirror. The internal beam is only the optical path inside the instrument, playing a role of stable compensation. These signals can form an algorithm and output the results according to the proportion. After calibration, a measured reading will be directly output.

 

Product Advantages:

Accurate, fast, reliable, maintenance-free and high stability

Halogen light source, high safety

Easy to calibrate and operate

Short payback period and high rate of return
