Xiamen production of composite plastic direct xiamen production of composite plastic direct source of the smell of hot melt adhesive: the smell of hot melt adhesive from the hot melt adhesive itself, is the essential characteristics of hot melt adhesive, from raw material, production process, the influence of the circulation. 3, food packaging industry: in recent years, food safety more and more get the attention of people, our life is also true that there are too many unsafe food, milk powder, rice, cooking oil, dead pork, fake, and expired mooncakes, expired milk, etc. , and even some domestic famous brands, propaganda 'victory by wisdom, victory by Germany' big companies are selling tainted milk, China user who really don't know what to believe and who should not trust, the whole image of the Chinese brand hit hard. Smell, especially is faulty, people would think is unsafe, so the food and drink beer manufacturer of hot melt adhesive were put forward such as no smell, no smell of glue lets the user feel safe, rest assured, the steadfast. If you use the viscometer, make the viscosity of the ink, glue and solvents have accurate control of the dosage, so will greatly reduce the number of residual ink, glue and quantity. 4, automotive interior industry: car, is the second largest industry as the leading industry, annual production of 22 million cars by 2014 above, China is power from the car to the car power shift. Car interior environment, people can't stand more and more harsh indoor environment, car brands made the car interior environment standard, standard for VOC. And VOC from auto interior materials, so the requirement of car interior trim stick or move hot melt glue VOC standards, require no volatile substances, demand has no smell. However, VOC standard car, but the smell also has many is unacceptable, VOC and the relationship between the odor becomes a research thesis. Here are some representative should use: (3) a variety of surface stress of the sandwich plate; (4) construction is convenient, fast curing. To explore the essence of smell: discussed here is the smell of the material, not a person's interest and meaning expression, such as the human spirit of temperament, smell. 8, the pur hot melt glue machine pressure plate after cleaned up, press the pressure plate shall be immediately into the new pur hot melt adhesive in barrel, avoid long time to get the pressure plate, exposed to air. Exposed to ultraviolet or visible light, 10 to 20 seconds can be cured. 1, smell concept: fast curing and improves the efficiency. Smell is to point to the object itself or send out the flavor. Bouquet: odor gas + =. Gas is gas, volatile matter, it is a substance that is usually small molecules, so easy to turn into gas. Taste is sensory perception, be equivalent to sensors, refers to the molecule in the senses ( Sensor) After the surface produce the quantity change ( Physical quantities can be electric, magnetic, optical, length or volume, ion flow, molecular flow, etc. ) Through to the CPU (the signals produced by, The brain) 。 So the smell is not refers to a substance, but the process of interaction between material ( From baidu encyclopedia) 。 Smell is a kind of feeling people foreign in material objects, different people have different feeling to the same kind of material, by the people's eating habits, work experience, education degree, personal preferences, the influence of such factors as a like the smell of another person may hate, a people hate the smell of others can be very like, really for all tastes. Sour, sweet, bitter, spicy, salty, is to be mixed, by feeling or sense of smell and feel. Xiamen production of composite plastic press the hot plate direct into the plastic bucket, lift cylinder pressure should be from small to large size, may not directly use the high pressure gas, prevent accidents, pay attention to the safety of the operator. Material as the temperature rises, the volatile gas concentration grows, are smell the smell of the heavier, vice scent is light. Usually volatile substances smell, the smell of heavy metals and other inorganic small. Smell is the inherent nature of the material, is one of the important features, material can be evaluation. In the production process, hot melt adhesive may also have a new odor sources, through the production process control can achieve the goal of reducing odor. Glue keep bad will solidify, the composite reinforcement becomes poor, has a great effect on printing quality. Xiamen direct produce compound rubber in logistics transportation of hot melt adhesive, may also be dyed into new smells. These ink left threw a pity, then, is not working, their performance has been changed to a dark and poor flowing property, impurities, scraping clean produce bubbles.
