Transmission color spectrophotometer for color consistency of polyurethane coatings
Polyurethane coating is a commonly used waterproof coating and is widely used in the field of wood products. In order to help wood products obtain different appearance colors, various colorants can be added to mix and color. If you want to control the color quality of polyurethane coatings, you can detect it with a spectrophotometer.
Application of polyurethane coatings:
Shipbuilders often use polyurethane to protect and extend the life of their products. It is very difficult to repair the old wooden boat and restore its previous performance, especially the decay of the wood, which must be replaced in time. Therefore, in order to extend the service life of wooden boats and avoid frequent maintenance, it is necessary to choose specific waterproof coatings to protect the wood from rapid decay. Polyurethane is such a coating with water-repellent properties that is widely used in wooden products. It can form a protective water-repellent coating on the surface of wooden products, thereby improving the durability of the product and extending various forms of wooden items. Life. In general, polyurethane is completely transparent to preserve the color of natural wood, but some oil-based polyurethanes may add other colors to give the wood a better decorative effect.
Of course, whether it is to retain the natural color of the wood or wood surface is formed in the new colors, manufacturers are required to conduct polyurethane color quality control, otherwise opaque polyurethane coating mixed with other variegated, it will affect the appearance of quality wood products. Therefore, manufacturers who can produce high-quality polyurethane coatings are more favored by customers and stand out from the fierce market competition. If they want to produce high-quality polyurethane coatings, they can use a transmission spectrophotometer to control color quality.
Spectrophotometer for color consistency of polyurethane coatings:
Color quality testing is essential for polyurethane coatings. The main advantage of polyurethane over other polymer products is that polyurethane is produced and sold in the final form in a laboratory or factory and can be used without any intermediate steps after manufacturing. As a result, manufacturers make polyurethanes that can ensure that they are colorless or have a predetermined hue. Impurities or inaccurate production processes can cause chromatic aberration problems in polyurethane, which can damage the final appearance of the customer's product. To ensure that the color of each batch of polyurethane is correct, the manufacturer must carefully measure the sample before shipping it to a distributor or customer.
To accurately measure transparent liquids such as polyurethane, manufacturers can use transmission spectrophotometers. This type of instrument measures the color of transparent and translucent materials by illuminating the sample with a controlled beam, which is then collected and analyzed on the other side. Using this instrument for measurement, users can quickly detect and quantify the color parameters of samples, thereby ensuring the color quality of polyurethane.
