"Spring 2011 (QTG) on-site polyurea technology training course" was held in Qingdao university of technology from April 9 to 12, 2011. This training is sponsored by the functional materials research institute of Qingdao university of technology, and co-organized by Qingdao Shamu Advanced Material co., ltd. and yantai zhifu zhenxing polyurethane material factory.
During the four days of training, teachers use QTG site construction teaching pattern, let the students in professor huang in nearly 20 years of experience and lessons, polyurea career experience real scene polyurea construction difficulties and learn the importance of spraying essentials, understand the "a polyurea, nine points of the construction of scientific meaning. Professor huang pointed out: a polyurea refers to the pure polyurea that really conforms to the scientific definition. Nine points of construction refers to the implementation of polyurea is much more complex and professional than ordinary coating, must receive professional skills training, and constantly practice and accumulate experience.
In the course of this training, the rapid identification of true and false polyureas, which is widely concerned, was emphatically explained. Professor huang has taught "eight" methods to quickly identify the true and false polyurea. They are: 1. 2. Manual identification; 3, according to the amino and hydroxyl hydrophobic, hydrophilic principle identification method; 4. Odor identification method; 5. Reaction status identification of true and false polyureas with the participation of trace water; 6. Reaction process and gel state identification of true and false polyureas; 7. Qtech-111 rapid identification method of true and false polyureas; 8, spray on the surface of water film identification method.
