Yinchuan complaints yinchuan pressure sensitive adhesive industry pressure sensitive adhesive complaints 1. Pur polyurethane hot melt adhesive to the surface of the adhesive material processing clean, dry, no dirt, no greasy, no dust, evenly apply the product in the adhesive surfaces and two surface bonding pressure, the clamps are available, and gently pressure adhesive tape or clog content of two sides, for glue to work under pressure, pressure time should be extended accordingly draping speed advice is 80 - 150 m/mm, drying temperature advice is 80 - 110 ℃ stored in shady and cool place and avoid direct sunlight, keep the temperature for 5 ~ 40 ℃ is suitable for PET aluminum plating film and paper combined with green products can be safely used in food, drugs, alcohol and tobacco, children's toys packaging processing appearance milky white or light yellow latex health and safety of 20 kg, 50 kg bottled definition 2: academic definition: pressure sensitive adhesive is a kind of have a combination of the viscous properties of liquid and solid elastic properties of the viscoelastic body; The viscoelastic body at the same time, have to be able to withstand adhesive contact two aspects of process and failure process of impact factors and properties. (1) the fabric paste with hot melt adhesive [ 2] Furniture furniture USES hot melt adhesive is a kind of special to the man-made plank paste adhesive, it is a kind of environmental protection, solvent-free thermoplastic rubber. Adhesive for sewing can reduce labor intensity, garment and clothing made of fine, fit, strong strong. Used in fabric paste mainly include polyamide hot-melt adhesive, such as cheese and polyurethane. Food with silica gel is made from silicate polycondensation of inorganic polymer gel material, ingredient is SiO2 · nH2O, its content is over 98%, avirulent insipidity, stable chemical performance, under the normal except hydrofluoric acid and caustic, not any response from the acid and alkali salt. From the late 1970 s, hot melt adhesive to begin to enter to wood industry, used for sealing side, plywood core, plate joining together, such as furniture tenon joint, early hot melt adhesive equipment is mainly dependent on the United States, west Germany, Italy and other countries of equipment, along with the hot melt adhesive equipment has become increasingly mature, stable, selection and use is suitable for the hot melt adhesive equipments of the furniture factory details, not only can improve the quality of the furniture and class, and can improve the production efficiency, reduce the difficulty of the panel is renovated, reduce labor intensity. (2) the lining cloth processing with hot melt adhesive, hot melt adhesive was heated to a definite temperature by solid into molten, namely when the coating to or sealing side of man-made board base material surface, cooling into a solid, the material with the base material of adhesive. Adhesive lining cloth is on fabric surface evenly Xu Bu made of hot melt adhesive. When used to adhesive lining cloth cut into the required shape and size, to be coated with hot melt adhesive side with other fabric materials ( The fabric) On the back of the hot-pressing bonding. It lining in the clothing layer, as a skeleton of a garment, simplifies the clothing processing technology and time, make the garment with light, beautiful, comfortable, insurance type, washable, durable effect. (3) : late because of the small water molecules than solvent-based adhesive, can penetrate into the surface of the material smaller pore, equivalent to cast anchor in the material surface, its late on and solvent adhesive, with some suitable for cast anchor porous materials, such as mesh cloth and EVA, the late strength is better than solvent-based adhesive; (3) glue barrel stacked shall not exceed 4 layer; Avoid direct sunlight and rain; 3 type water-based glue suitable shoes and shoes (4) the warehouse should be set temperature and humidity meter, advice within 5 ∽ 30 ℃, temperature control and record every day, such as the temperature is beyond the scope suggested, should take timely improvement measures, to ensure that the water-based adhesive; The rapid development of the electronics industry to drive the further development of conductive adhesive. Lining cloth processing general requirement for hot melt adhesive is a colorless, odorless, texture soft, rapid bonding, resistance to wet and dry wash, cannot have an effect on fabric, light resistance, etc. Can use a variety of hot melt adhesive lining cloth processing, almost all types of hot melt adhesive can be used, with much is ethylene - Vinyl acetate ( EVA) Hot melt adhesive, polyamide hot melt adhesive and high-pressure polyethylene ( HDPE) Hot melt glue powder, and different USES of hot melt adhesive and processing methods are also different. Yinchuan industry complaints so food-grade silicone pressure sensitive adhesive can be used as food, external use of desiccant. Hot melt adhesive stick to white opaque ( Strong type) , non-toxic, easy operation, continuous use without carbonization phenomenon have fast adhesion, high strength, ageing resistance, non-toxic, good thermal stability, film toughness, etc. 。 (3) the carpet back glue with hot melt pressure sensitive adhesive glue yinchuan industry complaints in which the vast majority of cases is the use of ethylene.
