. 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. Quzhou authorized packaging adhesive how to strengthen the fire prevention of engineering plastics additives are: halogen and non halogen ( Phosphate ester) Fire retardant. To join the softening point of low viscosity regulator, can achieve good bonding when penetrating, stick to the purpose. 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: can have different viscosity, curing speed,'s ability to fill the gap and the surface compatibility. 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 explain the hot melt adhesive for you under the machine, the working principle of the host: 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, shown on the thermometer temperature may have certain error, and the actual 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. Generally select paraffin wax, microcrystalline wax. 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. Quzhou authorization about packaging glue does not contain benzene, benzene, xylene, butyl acetate ester, acetone and other harmful substances, for the green products, can be safely used in food, drugs, alcohol and tobacco, children's toys and other packing materials processing notice if the glue stick on the skin, can clean water and soap. 3. Water-based glue in addition to the PE and PP materials, suitable for shoes fit between the use of all materials. 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. Quzhou authorization about packaging adhesive viscosity regulator is also the main auxiliary hot melt adhesive. If you are unwell seek immediate attention should be paid to prevent frostbite, under 0 ℃ storage for a long time can damage performance in 1 - after the 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. 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. Quzhou authorized packaging glue how is after polymerization of polymer resin. Quzhou authorized packaging glue
