Халуун хайлмал наалдамхай хольц үүсэх ба уусмал


Халуун хайлмал цавуунд хэрэглэхээс өмнө болон дараа нь, эсвэл хэрэглэх явцад хольц гарч болзошгүй. Яагаад ийм юм бэ? Тиймээс халуун хайлмал наалдамхай бодисын янз бүрийн төлөв байдалд нийцүүлэн хольц үүсэхийг судалж, дараа нь шийдлийг олох шаардлагатай байна.

Үүсэххалуун хайлмал цавуу 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 халуун хайлмал цавууs. Regardless of the color, initial viscosity, and yellowing resistance of the халуун хайлмал цавуу, 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 халуун хайлмал цавууs 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 халуун хайлмал цавууs.

       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 халуун хайлмал цавууs, 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 халуун хайлмал цавууs, 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.
