Xiamen henkel glue dealers xiamen henkel glue dealers to press the hot plate into plastic barrels, size of lifting cylinder pressure should be from small to large, may not directly use the high pressure gas, prevent accidents, pay attention to the safety of the operator.
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.
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.
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.
In production, and many times is ink, glue and solvent viscosity add not constant, the printing ink, glue remaining number increase, the number gets bigger.
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.
Hot melt adhesive, consists of main resin (
, viscosity resin, thinner or softening oil, antioxidant and other raw materials, according to a certain production process, heat melt, fully mixing, forming, cooling preparation.
1, smell concept: refers to the object itself or send out a smell smell.
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 (
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,
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 henkel glue dealers in logistics transportation of hot melt adhesive, may also be dyed into new smells.
Anaerobic adhesive UV type: single-component or bi-component, solid.
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.
Thermal decomposition of the initiator for when heated has triggered active free radicals can break down the material, a general by the initiator molecules are split into two free radicals, such as persulfate in alkaline and neutral or acidic solution not to carry on the thermal decomposition process is as follows: the performance test, hot melt adhesive concept: hot melt adhesive is short for hot melt adhesive, adhesive industry is an important category of solid content, no solvents, environmental non-toxic, fast curing characteristics, widely used in automatic packaging, hygiene products, labels, tape,, automotive, construction, furniture, printing and binding, footwear, clothing and other industries, usually is refers to the present solid at room temperature, when heated to a certain temperature and melt into sticky liquid, after coating, wetting is sticky material, after pressing, after cooling to room temperature, in a few seconds to complete adhesive bonding.
Fast curing, and improve the efficiency.
Xiamen henkel distributor 8, glue to 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.
In the manned and unmanned spacecraft adhesives are widely used.
