Lijiang industry industrial rubber like lijiang industry industrial rubber like attending a bowl of residual glue, glue don't fall back to the packing barrels, so as to avoid pollution of the glue barrel of glue. Using high temperature pur polyurethane hot melt adhesive, and really pay attention to the following items: 1. 23) By bonding surface treatment: hot melt adhesive for bonding material surface treatment no other adhesive is so strict, but be dust on the surface of the adhesive material, oil should also do the appropriate processing, their best to make the hot melt adhesive glue. EVA hot melt adhesive after melting, the pale brown or white. 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. Lijiang industry industrial glue how EVA hot melt adhesive is a kind of without solvent, excluding water solid meltability polymer; It is solid at room temperature, heat can melt to a certain temperature to flow, and has a certain viscosity liquid. 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. Application of construction industry on the adhesive assembly are: (1) day and night temperature difference is big, strong radiation, glue must withstand harsh environment. 2. Heating cleaning solvents, automotive interiors industry: car is the second largest industry, is a big industry, annual production of 22 million cars by 2014 above, China is power from the car to the car power shift. Civil engineering in the construction industry, adhesive is mainly used for structure and decoration, making many engineering components, such as cork plywood, laminated board, laminated board, and some of the same component, plastic floor, carpet, ceramic tiles, wallpaper paste. 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. Five, ink, glue viscosity change with strong read relationships ( 4) Grafting modification are just the right amount of styrene monomer are added into the polyurethane emulsion, made by in-situ poly polyurethane grafted styrene emulsion, improves the adhesion and water resistance. 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. How about lijiang industry industrial glue but, VOC standard car, but the smell also has many is unacceptable, VOC and the relationship between the odor becomes a research thesis. C, before using cleaning solvents, must check whether indoor air liquidity is good, avoid to use open flame, not under the environment of air does not flow cleaning pur hot melt adhesive machine. Color: brown 2. Soft, good elasticity, resistance to kink deformation; Product category editing epoxy resin type: single-component or bi-component, for the majority of base material has good bonding properties, resistance to chemicals. Lijiang industry industrial glue how 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.
