Matters needing attention of Weiwang EVA hot melt adhesive stick in book binding
As we all know, EVA hot melt adhesive has good advantages, such as green environmental protection, high bonding and curing, affordable cost, suitable for continuous automatic high-speed operation and so on. It is widely used in many industries, among which book album operation is one of them. Printing manufacturers need to use this material. Hot melt adhesive can be perfectly integrated in book binding operation, but sometimes there are some problems in the process of book binding, such as sudden degumming, Or the solubility can't be bonded. Combined with the above points, we sorted out the following points about the hot melt adhesive problem in book binding. Next, let's see what the impact will be?


1、 Improper operation of EVA hot melt adhesive temperature

Temperature control is an important link in the use of hot-melt adhesive. When the temperature of the adhesive is too high, it will be easy to wire drawing although the fluidity is good. If the temperature is too low and the sol is not complete, it will lead to poor fluidity of the adhesive and is not conducive to uniform and sufficient gluing. Therefore, according to these two points. Book binding manufacturers need to control the use of glue according to the production ambient temperature.


2、 Different softening point

The composition and performance of hot melt adhesives of different brands from different manufacturers are different, and the softening point will be different. Some manufacturers use low-cost raw materials, and then charge them well. If the softening point of the produced rubber rod is not good, it will lead to the imperfection of book binding operation. We need to make appropriate adjustments to the fluidity and softening point of the glue, so as to ensure the smooth flow of the glue, good viscosity and high utilization rate.


3、 Glue quality of hot melt adhesive manufacturer

The quality of hot melt adhesive affects the firmness of book block binding. Now some inferior books on the market are easy to rot after purchase. They can't stand repeated reading, and there are problems of degumming and loose glue. Readers also have opinions. This is because some book manufacturers have purchased inferior hot melt adhesive rods and good hot melt adhesive. EVA raw materials are used, with high technical content and wide practicability. Under different temperature environments, It can also have a good bonding effect. If you accidentally buy low-quality glue raw materials, it is not suitable to bond thick books, so it will be prone to book loose pages degumming. As a hot-melt adhesive manufacturer, Weiwang uses high-quality raw materials when producing hot-melt adhesive rods, strictly controls production and adheres to the principle of quality. A good hot-melt adhesive belongs to Weiwang.

Now we know the impact of hot melt adhesive on book binding, so when book binding manufacturers buy hot melt adhesive, they still need to look at several more, depending on the high praise rate of the market and the establishment time of the manufacturer. Generally, for manufacturers with a long establishment time, the quality is still trustworthy, and Weiwang hot melt adhesive is worthy of your trust.
