The connection and difference between hot melt glue machine and cold glue machine?_News_reactor | jacketed reactor | stainless steel reactor

In order to understand the connection and difference between hot melt glue machine spraying and cold glue machine spraying, it is necessary to understand their uses and implementation objects.
Both hot melt glue machine and cold glue machine are special equipment for spraying and gluing, and the application fields are very different;

The hot melt glue machine uses gel glue, also known as jelly glue. Because the shape and performance of jelly glue are a bit like jelly, it also becomes jelly glue, which is characterized by: fragrant smell, strong viscosity, good fluidity, strong folding, and fast drying time. Therefore, the hot melt glue gluing machine can avoid the shrinkage, mildew, and slow drying of the white latex, and can also solve the problems of deformation, brittleness, blistering, etc. The thing that comes out is very straight, very straight, and does not bend.

The cold glue machine uses general water-based glue such as white latex. Performance: White latex is not afraid of moth-eaten rat bites, will not mold and deteriorate, is harmless to the human body, easy to wash, can be diluted at will, and is easy to use; cutting does not damage the blade, suitable for binding. The disadvantage is that this adhesive has poor water resistance and poor heat resistance. Application: Especially suitable for bonding of porous materials, such as paper, fabric, leather, wood. The drying speed is very slow, and it is not easy to set the shape. If it is used to paste the hardcover bookcase, the bookcase will warp and uneven due to the penetration of moisture and the short drying time.
With the increase of living standards, people have more and more requirements, such as cold glue machine can not be used in the food industry, and hot melt adhesive is an environmentally friendly material, widely used in: disposable hygiene materials, maternal and child hygiene products, no Textile, bookbinding, shoe industry, medical supplies, furniture manufacturing, automobile manufacturing, air filter production, adhesive tape, trademark labels, packaging industry (carton sealing, color box sealing) and express bags and other major industries .

The main difference is that the cold glue spraying machine has a small range of use, is not environmentally friendly, has certain harm to the human body, and has low viscosity, while the hot melt glue spraying machine has become one of the indispensable mechanical equipment for many manufacturers. Every household is equipped with a hot melt glue machine. From the perspective of future development, the cold glue spray machine will inevitably be diluted in people\'s sight, and it will be replaced by a hot melt glue machine.
