How much money how much money the daqing HENKEL glue daqing HENKEL glue after 12, changing the pur polyurethane hot melt adhesive, must wait for pur hot melt adhesive machine heating at least 20 minutes before start the pump and motor, such as immediately start the pump and motor can cause polyurethane gear pump is damaged, reduce the service life of pur hot melt glue machine. The apparent density: 0. 48 - 0. 52g/cm3; Rest Angle: 30 - 35 degrees. Source of the smell of hot melt adhesive, hot melt adhesive is a kind of plastic adhesives, to a certain temperature range with the temperature change and change its physical state, and chemical properties unchanged, and its non-toxic tasteless, environmentally friendly chemical products. Bonding strength: 1 or higher. 5 - 2. 0公斤/ 25毫米; Wash resistance: 5 or more times. 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. 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. 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 much is the daqing HENKEL glue material and shuikou resolution: up from color to distinguish the shuikou material products in the high proportion of prone blond, black. 3, can put the hot melt adhesive melts tested on tensile strength, tensile strength of hot melt adhesive is not qualified. Belongs to water-soluble adhesives, non-toxic, without excitant odor. On the market at present there are mainly three kinds of pressure sensitive adhesive, solvent, hot melt type and water-based ( The emulsion) Type. 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. How much money the daqing HENKEL glue material floolwing couldn't do the transparent products, make ordinary products material floolwing is not greater than 35%, the ratio of shuikou material can reach the requirement of low products. In the 1960 s.
