Ыстық балқымалы желім қоспаларының түзілуі және ерітіндісі

2021/03/16

Қоспалар ыстық балқымалы желімдерде қолданар алдында және қолданғаннан кейін, тіпті пайдалану кезінде пайда болуы мүмкін. Неге бұл? Сондықтан ыстық балқымалы желімнің әртүрлі күйлеріне сәйкес қоспалардың түзілуін зерттеп, содан кейін шешімін табу керек.


Қалыптастыруыстық балқымалы желім 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 ыстық балқымалы желімs. Regardless of the color, initial viscosity, and yellowing resistance of the ыстық балқымалы желім, 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 ыстық балқымалы желімs 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 ыстық балқымалы желімs.


       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 ыстық балқымалы желімs, 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 ыстық балқымалы желімs, 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.
