PUR hot melt adhesives are a type of adhesive that is commonly used in industrial applications. PUR stands for polyurethane reactive, which refers to the chemical composition of the adhesive.
These adhesives are typically applied in a molten state and then solidify as they cool. They offer a number of advantages over other types of adhesives, including:
1. Strong bond: PUR hot melt adhesives create a strong and durable bond between materials. They can bond a wide range of substrates, including wood, plastic, metal, and foam.
2. Fast curing: PUR hot melt adhesives have a relatively fast curing time, allowing for quick assembly and production processes.
3. Heat resistance: Once cured, PUR hot melt adhesives have excellent heat resistance. They can withstand high temperatures without losing their bond strength.
4. Moisture resistance: PUR hot melt adhesives are resistant to moisture and can be used in applications where the adhesive may come into contact with water or other liquids.
5. Flexibility: PUR hot melt adhesives remain flexible even after curing, making them suitable for applications that require some degree of flexibility or movement.
6. Chemical resistance: These adhesives have good resistance to chemicals, making them suitable for applications where exposure to harsh chemicals is expected.
7. Environmentally friendly: PUR hot melt adhesives are considered to be more environmentally friendly compared to other types of adhesives. They do not contain solvents or volatile organic compounds (VOCs), making them safer to use and reducing the impact on air quality.
Overall, PUR hot melt adhesives are versatile and offer a range of benefits that make them suitable for a wide range of applications in industries such as packaging, automotive, construction, and woodworking.

Edible oils must be fatty acids and several physiologically active lipids. Of course not all the components of the oil are beneficial to human health. Therefore, the use of oil smoke point instrument to test the quality of oil and then evaluate the merits of edible oil, has a very important significance for human health. The thermal stability of the grease with high smoke point is better within a certain period of time. The sanitation conditions of the fried food and cooking operation environment are good and the food flavor is good. However, the blind pursuit of high smoke point oil products is bound to be affected by the high temperature of the processing process. If the process conditions are not properly controlled, not only will the oil double bond isomerization and polymerization occur, the melting point will increase, the digestion and absorption rate and nutritional value will be reduced, but the natural antioxidants in the oil will be greatly reduced, the storage stability will be reduced, and the oil-containing food shelf Shorter period.
In the determination of the quality of edible oils and fats, it is not possible to rely solely on the detection of grease smoke points by means of grease smoke point meters. It is also necessary to comprehensively consider the various quality indicators of grease products, select the good processes and grasp the process conditions of the oil refining refining processes in order to An edible oil product with good quality and long shelf life is obtained.
Application of Oil Smoke Point Apparatus in Studying the Nutrition of Edible Oil
High-precision poly-distillation oils are not uncommon in the market, and such consumption structures have certain blindness, and are not healthy and reasonable. Oil is composed of triglyceride, a major component, and a small amount of lipids and fat accompanied by fat. It is one of the three major nutrients of human food. It is not only a good source of calories, but also makes foods delicious and appetizing. The human body provides a variety of nutrients that cannot be synthesized in the body and that are necessary for maintaining health. The grease smoke point meter is an important instrument for measuring the smoke point of fats and oils and is an inspection instrument for oil quality.
