Shaanxi authority how to use water-based glue shaanxi authority how to use water-based glue as fiber adhesive cat agent should be washable and dry cleaning. At present good quality hot melt adhesive can be used in the field of industrial manufacturing, heat resistance performance and flame retardant performance is guaranteed, the current can reach the quality requirements must be big brand products, such as ke, Moore, focus on the study of the hot melt adhesive, provide customized hot melt adhesive application solutions, wide range of USES, can be applied to new energy, military industry, aviation, shipbuilding, electronics, automobiles, instrument, power supply, high iron, and other areas of the industry. The known literature review: the ratio of methyl methacrylate (mma) and butyl acrylate trade 0; The proportion of hydroxy ethyl acrylate and butyl acrylate should 1:6 0 [ 6] ; Ammonium persulfate initiator dosage as the monomer volume of 0. 5% [ 7] ; Emulsifier dosage to CMC value is easy for unit 1. 5% [ 7] ; Protect the adhesive positioning monomer amount of 2. 2% [ 7] 。 Operating temperature in 100 to 600 of ( - 37 - 135oC) 。 Can have heat cycle performance of products. Hot melt adhesive is a kind of plasticity strong adhesive, and the adhesive can be adhesive, and a variety of substances can changes with temperature changes in the nature, after curing adhesion, adhesive strength is big, so many industries can use this kind of adhesive. If the adhesive is for ordinary families, the quality is not important. If it is used in the industrial field, requires attention to quality, so how to determine the quality of the hot-melt adhesive? Because the resin is the main material of plastic tightly adhering, so paint viscosity fastness with the size of the printing ink viscosity, choosing the appropriate viscosity, size of pigment adhesive fastness. 1, can under the professional instrument for testing analyzing the composition of hot melt adhesive, so that we can get the accurate data. 2, can also be observed in appearance, if the hot melt adhesive glue type, do manual work is coarser, then the quality. Shaanxi authorized water-based glue is how to use 6, pur polyurethane hot melt adhesive machine after the break with hot melt glue barrel must be thoroughly clean up on the hot melt adhesive pressure plate immediately leave the pur hot melt adhesive, in cleaning up pur hot melt adhesive machine heating plate, the cannot use any hard tools, pressure plate, teflon coating to prevent scratches. ( 5) Vinyl emulsion dispersion modified isocyanate (can be Or its pre polymers) Organic solution dispersed in the aqueous solution of polyvinyl alcohol, carboxymethyl cellulose food, beverages, instant noodles, basic resin, beer, etc. Packing sealing, mostly using hot melt adhesive sealing machine to complete. 3, can put the hot melt adhesive melts tested on tensile strength, tensile strength of hot melt adhesive is not qualified. Shaanxi authorization water-based glue is how to do maintenance pur moisture reactive polyurethane hot melt adhesive machine, need to take the following described the main safety precautions: many poly acid amine ternary copolymer can be used as hot melt adhesive machine base. They are widely used in fiber cat in aspects and so on. Adopting solid structure, strengthening concrete technology in the bridge construction, large stadiums, underwater tunnels, the lighthouse pedestal and similar are widely used in construction. Used by the tool before drying of glue can be used warm water to clean. 4, hot melt adhesive, observe whether there is a powdery material after melting, if there are captions powdery material packing, adhesive performance is poor. 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 greatly speed up the binding, which USES hot melt glue technical indicators are as follows: thickness: 0. 1 - 0. 205MM3. No crack, long service life, cold resistant high temperature; Acrylic adhesive silicone type: single-component or two components, can be a solid, is friendly to users. General coating concentration control in 20% 16-30%, viscosity It is advisable to 20 seconds. Shaanxi authorization water-based glue is how to use determine the oil-water ratio of 54:46. This has made product performance more good on average.
