Using high temperature pur polyurethane hot melt adhesive, and really pay attention to the following items: the VOC from auto interior materials, so the requirement of car interior trim stick or move hot melt glue VOC standards, require no volatile substances, demand has no smell. Application of construction industry on the adhesive assembly are: (1) day and night temperature difference is big, strong radiation, glue must withstand harsh environment. A, hot melt adhesive can condense into a solid, the high temperature of liquid condenses into solid state even in a period of time, still with a high temperature, once touch a person's skin, can cause serious injury. Urumqi industry how to use water-based glue car interior environment, the indoor environment, people more and more can't put up with irritating car brands made the car interior environment standard, standard for VOC. The current construction of adhesive there are two main problems: one is adhesive when a lack of proper temperature control; Second, no suitable process equipment, therefore, still need to adopt mechanical reinforcement. B, moisture near the pur reactive polyurethane hot melt adhesive machine working or hold pur hot melt adhesive glue barrel, be sure to pay attention to whether or not they wear safety work clothes, gloves and goggles. EVA hot melt adhesive by basic resin, tackifier and viscosity regulator and antioxidant components, etc. 2.

A, using solvent cleaning heating with viscose element, never use the fireworks or no temperature control of heating equipment cleaning, general pur moisture reactive polyurethane hot melt adhesive machine can't operate 280 degrees when cleaning and maintenance. B, do not use for paint solvent cleaning with viscose element, because this kind of high volatile solvents, easy combustion and explosion, and can produce poisonous gas at high temperatures, and easily damaged pur hot melt adhesive machine heating the teflon coating on the pressure plate. Urumqi industry how to use water-based glue attending the surplus glue, glue bowl don't fall back to the packing barrels, so as to avoid pollution of the glue glue in the bucket. However, VOC standard car, but the smell also has many is unacceptable, VOC and the relationship between the odor becomes a research thesis.
