Enpurte ka parèt nan adhésifs fonn cho anvan ak apre itilize oswa menm pandan itilizasyon. Poukisa sa a? Se poutèt sa, li nesesè yo etidye fòmasyon nan enpurte selon eta yo diferan nan adezif la fonn cho, ak Lè sa a, jwenn yon solisyon.
Fòmasyon nanadezif fonn cho is the result of the joint action of a variety of chemical
substances. Which substance is impure, or which two substances produce foreign
bodies when reacting, these are the categories to be considered in the
formation of impurities. Let me talk about impure raw materials first. The raw
materials are used in the production of adezif fonn chos. Regardless of the
color, initial viscosity, and yellowing resistance of the adezif fonn cho,
the role of the raw materials is irreplaceable. However, if the raw materials
are impure or the physical properties are unstable, the possibility of
impurities will be greatly increased when used in the production of hot melt
adhesive products. But sometimes adezif fonn chos may have black spots and
uneven colors, which may be caused by uneven mixing of raw materials or
conflicts in physical properties between various raw materials during the
production of adezif fonn chos.
Clean the glue
pot, improve the glue application environment, and make the hot melt glue
impurities disappear. Hot melt adhesive needs a melting process before use.
Other impurities may be mixed in the whole process. For example, when gluing a
book, paper scraps and dust may fall into the glue pot; there are more or less
carbides deposited over the years in the furnace, which may be mixed with the
newly melted glue, and so on. Perhaps a little dust will not have much
influence on the use and performance of adezif fonn chos, but what if the
adhesive itself must match the appearance of the product? This requires special
attention from glue users.
In order to
avoid impurities in adezif fonn chos, manufacturers and users of hot melt
adhesives must know the reasons for their formation. As a hot-melt adhesive
manufacturer, you need to be responsible for the quality of the hot-melt
adhesive and have requirements for the quality of the raw materials used, which
provides a basis for producing high-quality products without impurities. As a
hot melt glue user, the glue application equipment also needs to be in good
working condition like hot melt glue, and it can be cleaned regularly according
to the residual degree of the glue tank and glue gun.
