    Hot melt is the use of hot melting machine through heat to melt the hot melt, the glue after the melt into a liquid, through the hot melter's throat and spray gun, sent to the surface of the adhesive, hot melt cooled after the completion of bonding, it can meet the requirements of carton box, and overcome the previous form of carton box defects.
    the advantages of hot melt
    1, fast, the entire bonding process only takes 1-3 seconds to complete (or even faster).
    2, the use of tools to occupy less space, such as hot melt body small, placed in a corner of the plant is very convenient, the use is also very convenient

    .
    3, the production cost per unit of products is the lowest.
    4, hot melt adhesive bonding effect is good, high adhesion strength is very high, and the overall strength of the adhesive carton is strengthened, so that the carton is not easy to deform and crack.
    5, the use of hot melt without waste treatment problems. In line with environmental protection requirements, in line with the packaging requirements for export products.
    6, hot melt it has anti-theft effect, can cite whether the packaging objects have been opened without authorization.
    7, can adjust the different dispensing methods, to play the role of identification and anti-counterfeiting.
    Chargeable melt characteristics
    hot melt is a solvent-free, water-free, 100% solid meltable polymer products, solid at room temperature, heating melt to a certain extent into a flowing and a certain amount of adhesive liquid adhesive, its melting is light brown translucent body or white.
    the main components of hot melt, that is, the basic resin is ethylene and ethylene acetate in high pressure together, and then with adhesives, viscosity regulators, antioxidants, etc. to make hot melt.
    hot melt it is a 100 percent solid, heated into a molten state, contact with the air cold surface and then solidified, and then completed in just a few seconds. Compared with solvent-based and water solvent-based, the main advantages are as follows:
    1, instantaneously, to ensure efficient production.
    2, no need to dry equipment, save space.
    3, non-toxic, non-flammable, no risk of pollution.
    4, long-term storage, will not go bad.
    There is the direction of the development of hot melt
    in the future, under the trend of globalization of the hot melt industry, demand will be more diversified, and gradually large-scale hot melt enterprises, will also have sufficient strength to do basic research, so as to achieve advantages in the product homogenization of serious market, so the development of technology is almost inevitable.
    1, high-strength hot melt
    bonding strength is the core performance of the glue, hot melt to be applied to some very high strength requirements of the occasion, especially to withstand greater structural stress, it is necessary to improve the bonding strength.
    strong polarity and good immersion is often the characteristics of the adhesive can achieve high bonding strength, hot melt because there is no solvent, fluidity and immersion is a short plate, improve the bonding strength of hot melt glue should mainly start from the polarity and immersion of hot melt.
    , high-speed hot melt
    the high efficiency of hot melt is recognized, because as long as the hot melt cooling can produce hardening, thus forming bonding. Cigarette mouth stick bonding speed of up to 20,000 pieces / minute, book binding up to 18,000 books / hour, diapers production up to 1000 pieces / minute.
    future, it is possible to further improve the speed of hot melt glue application, expand this advantage, mainly from accelerating the speed of hardening, improve thermal viscosity, reduce material ratio heat, equipment optimization to achieve.
    Three, low temperature hot melt glue
    application temperature is one of the most important concerns of material engineers, low application temperature can not only reduce material damage, extend the service life of equipment, save energy consumption, but also reduce carbon emissions of public welfare effects, so, low temperature hot melt will certainly be a very promising research direction.
    , low density hot melt
    in many occasions, reducing material density to achieve lightweight has many advantages, such as reducing energy consumption, saving resources. The bonding strength of the adhesive is more dependent on the bonding area than on the weight of the glue itself, which makes the low density hot melt a reliable research direction.
    low density can be achieved not only by improving material densities, such as the use of polyolefin raw materials, but also by manufacturing processes, such as foaming hot melts.
    5, odorless hot melt
    in people's health concerns more and more situation, especially in the automotive, sanitation, food, toys, furniture and other industries, odorless hot melt is the best product to reduce the concerns of end-consumers.
    odorless materials should be achieved through improvements in raw materials, minimizing small molecular substances, using low odors or even odorless raw materials, such as hydrogenated pine esters.
    6. Materialized hot melt
    through a special molding process, the hot melt glue into a membrane-like, mesh, ribbon, wire-like material, will become a hot melting glue development trend. Today, hot melt film, hot melt film, hot melt tape, hot melt glue line market is growing at a high rate, such hot melt glue materials and other materials together, more conducive to downstream enterprises to achieve large-scale production and clean production.
    7, biodegradable hot melt
    environmental protection is a big trend, at the same time environmental protection is also a relative concept, hot melt glue, although it belongs to environmental protection glue, is limited to harmless environmental protection, not in the recycling or biodegradable level of environmental protection. In the future, if we can develop hot melt products that are easy to recycle or can be degraded naturally, there must be good prospects for development.
