How about food grade rubber industry in anhui anhui industry how is food grade rubber pressure-sensitive adhesive composition of 3. Emulsion viscosity with the method of rolling ball test. The apparent density: 0. 48 - 0. 52g/cm3; Rest Angle: 30 - 35 degrees. Is the use of hot melt glue by heating the hot melt adhesive, hot melt adhesive machine melt glue after become a kind of liquid, by hot melt adhesive machine hot melt rubber hose and hot melt glue gun, to be adhesive surfaces, hot melt adhesive cooling after completed the glue. Bonding strength: 1 or higher. 5 - 2. 0公斤/ 25毫米; Wash resistance: 5 or more times. In the 1960 s. This kind of hot melt adhesive can be divided into polyamide ( PA) , polyester ( PES) , polyethylene ( LOPE and HDPE) And polyester amide ( 豌豆) And so on, this kind of adhesive has passed five achievements appraisal, complete national '>' research, 'five-year' research project in hebei province, won the national invention, tianjin, hebei science and technology achievement prizes at the three a, won the national invention patent. Early pressure sensitive adhesive is made from natural rubber and viscosity resin were dissolved in toluene and heptane, system solutions of the pressure sensitive adhesive coating on paper or crepe tape can be obtained. Book binding with food, drinks, instant noodles, and beer, the packing sealing, mostly using hot melt adhesive sealing machine to complete. Book binding industry have been swept away the old line, binding, using hot melt adhesive technology, not only improve the quality of bookbinding, more important is to speed up the binding, which USES hot melt glue technical indicators are as follows: how about anhui industries food-grade plastic TPU plastic raw materials and nozzle: raw material is directly never drawn out from inside the oil processing, shuikou is after a high temperature molding plastics, raw materials of chemical stable performance and physical performance is good, the nozzle of the physical is much less than the raw material, easy to brittle, is easy to crack, toughness is far less than the raw material, its forming the more times its expected more brittle. Can say, in modern people's life, the application of hot melt adhesive is everywhere. 3, can put the hot melt adhesive melts tested on tensile strength, tensile strength of hot melt adhesive is not qualified. Anhui industry food grade glue what belongs to water-soluble adhesives, non-toxic, without excitant odor. 6 water-based adhesive and solvent-based adhesive glue brush should use different cleaning fluid immersion; Water-based glue process features all landowners capacity of about 500 ml of plastic bowl, and equipped with a suitable cover to dress up the glue; Search the public number: WPU - 88 China adhesive platform 8 pressure sensitive adhesive ( pressuresensitiveadhesive, PSA) Refers to the bonding process of pressure sensitive adhesive, can be used in the process of using the stomach pressure bonding was glued surfaces, commonly used to produce label, plastic tape and protection, etc.
