Guizhou HENKEL glue contact HENKEL glue contact car indoor environment in guizhou, the indoor environment, people more and more can't put up with irritating car brands made the car interior environment standard, standard for VOC. Using high temperature pur polyurethane hot melt adhesive, and really pay attention to the following items: 4, car interiors industries: automobile is China's 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. 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. Guizhou contact HENKEL glue and 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. Has the very good performance, basic no curing volatiles release. 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. Book binding with hot melt adhesive film is mainly divided into two major categories of thermoplastic and thermosetting, mainly used in electronic products, nameplate, plastic, hardware, mobile phone window frame and the front cover of the adhesive; Even in the uneven surface of adhesive also can obtain good effect. 2. 1 heating cleaning solvents. 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. 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. 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. Guizhou HENKEL contact EVA hot melt adhesive is a kind of glue 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. 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. 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.
