     The national in the use of Eva hot melts in the unit can meet the requirements of the above standards very little. So in some areas, when using hot melts, many times appear in summer temperature high colloid is not easy to solidify and cooling hardening, cut book sticky knife, Bubbles too much, books are not stereotyped problems; when the temperature is low in winter, the adhesive is open, the curing time is shortened, sticky or sticky, and the book core breaks. Also has the area humidity is too big, achieves the $number, the package on the cover book is not stereotyped, cannot carry on the cutting and so on. These phenomena are directly related to the temperature and humidity of the workshop.EVA Hot Melt Glue Sheet

The unconditional enterprise unit, must strive to create the condition, must first to the management personnel and the worker carries on the scientific, the standardized management production education. Only advanced equipment and materials, and human technical quality does not improve, is not suitable for modern production needs.EVA Hot Melt Glue Sheet

    In the absence of the above conditions, some temporary measures should be taken to if the summer temperature is high, the temperature of hot melts can be lowered 5~10℃ to improve its curing speed; in winter, when the temperature is low, it can also increase the temperature of 5~10℃, so that the opening and curing time of the gum slightly slow some, basically meet the required requirements, So that the finished books can meet the standard.EVA Hot Melt Glue Sheet
