The lijiang how professional pressure sensitive adhesive with chemical performance enhancements: how to use professional pressure sensitive adhesive stabilizer, antioxidant, surface modification agent processing. No matter be six or four standard, by the assessment team for at least three odor evaluation. Assessment team members must go through professional knowledge training, have the professional knowledge of odour, do not have the habit of smoking, drinking, diet excitant food, smell sensitive, has the characteristics of justice, fairness, integrity. The smell of the different enterprises have different testing standards, to simulate the hot melt adhesive application requirement is to smell method, such as the same amount of the same kind of hot melt adhesive in different size but same sealed in the jar, heated to a temperature point after how much time, take out the cooled to room temperature, open the lid, the reviewers sniffing, it is concluded that the respective evaluation value, record down, do three - over and over again Five times, it is concluded that the average for the final evaluation results. Lijiang how professional pressure sensitive adhesive with 5, only qualified personnel to pur moisture reactive polyurethane hot melt adhesive machine for maintenance work. Synthetic wax ( PE or PP) , Buddha wax, etc. A lot of customers on the hot melt adhesive machine working principle is not clear, there will be various aspects. In fact, hot melt adhesive machine is a kind of simple equipment. Host work 'content' is the hot melt adhesive melt, and then through the pressure type, delivery to lose hose or directly spray adhesive for spraying, compound, and so on. Under the beautiful swan explain for your hot melt glue machine, the working principle of the host: join the softening point low viscosity regulator, can achieve good bonding when penetrating, stick to the purpose of. A lot of customers on the hot melt adhesive machine working principle is not clear, there will be various aspects. In fact, hot melt adhesive machine is a kind of simple equipment. Host work 'content' is the hot melt adhesive melt, and then through the pressure type, delivery to lose hose or directly spray adhesive for spraying, compound, and so on. Beautiful swan below for you to explain hot melt glue machine, the working principle of the host: its function is to increase liquidity in colloid, solidification speed regulation, to achieve the purpose of strong rapid binding, hot melt adhesive for big and won't be able to or not easy flow, difficult to penetrate into the book, is not to be strong. Hot melt adhesive coating machine, and other hot melt adhesive machine principle of work is pretty much the same, there is a heater, in the process of heating, because the thermal conductivity is different, in the process of using, the thermometer display on glue may have certain error, and the actual temperature in the process of use, we can't according to the one-time interpretation of temperature, in a certain time interval, of temperature measurement for many times, in this case, the temperature of the test will be more accurate, can we call temperature side, more accurate and is more convenient for use. Very durable, it is mainly used for aerospace and industrial the sealing of the window. The origin of the hot melt coating machine in Europe and the United States and other developed countries, there is no long history of national development, such as technology is relatively mature, about decades in our country. Lijiang is how to use professional pressure sensitive adhesive polymerization reaction to obtain high polymer resin. Polysulfide type product can be resistant to all the smoke. Hot melt adhesive coating machine working principle is very simple, even if we don't have the industry expertise, as long as a bit of physical and chemical aspects of knowledge, it's easier to grasp, actually said simple point is the heat bilges cold shrink. While using the principle of not very complicated, but in the process, bring convenience to our some production life work really huge, a feature is to save the drying equipment, this not only saves redundant procedures, eliminating the dryer and so on equipment cost, it is kill two birds with one stone. Another big advantage is the low consumption, hot melt adhesive melting point is not very high. With a fixed quickly into a liquid. And solid hot melt adhesive in transportation and storage at ordinary times is more convenient, the process and to compare before is arguably has incomparable advantages. Is so much advantage is hot melt machine since their introduction, favored by the market constantly. Lijiang professional pressure sensitive adhesive should be paid attention to how to use if you are unwell seek immediate antifreeze, will destroy the performance under 0 ℃ storage for a long time in 1 - product use glue 3 minutes can be repositioned, and maintain a good viscosity PH 7. 0 ~ 9. 0 in use process should be tightly covered at any time, in case the glue liquid crust, do not entry, can not let the child contact ( 3) Pressure sensitive adhesive main body whether polymer crosslinked nCH2CHCOO ( CH2) 3甲基→- ( CH2CHCOO( CH2) 3甲基] N - three group of pressure sensitive adhesive test time is respectively: 21 h, h, 33 h. Can have different viscosity, curing speed, the fill the gap of the surface finish and compatibility. . PUR reactive hot melt adhesive, it is through the reaction of moisture curing, also can saying is the water molecules through chemical reactions into a solid, chemical reaction, reaction time, can according to the factors and the contact area and so on in the air. Lijiang how professional pressure sensitive adhesive with 3. Water-based glue in addition to the PE and PP materials, suitable for shoes fit between the use of all materials. Lijiang how professional pressure sensitive adhesive with no two identical people, and no two leaves are the same, although their names with ink, but still there's a big difference in terms of use.
