Lishui boss glue complaints of lishui boss complaints to balance the pressure sensitive adhesive glue adhesive attraction and cohesion, adhesive performance and water resistance, weather resistance, solvent resistance, you must first determine the dosage of all kinds of raw materials. 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] 。 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. 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? (1) the whole lining wall surface and the wood frame adhesive; (2) for vacuum resistance, high strength, good reliability. 1, can under the professional instrument for testing analyzing the composition of hot melt adhesive, so that we can get the accurate data. If the printing ink, glue composite viscosity is too small, excessive solvent content in the ink, glue, and resin, pigments and other components are relatively less, so can't form a smooth layer when dry, so white, become dull, lack of gloss. 2, can also be observed in appearance, if the hot melt adhesive glue type, do manual work is coarser, then the quality. Lishui boss complaints should be soft monomer and hard monomer, glue them modified functional monomer on the composition of interdependence. Composite glue in solvent can cause more bad, bubbles, poor fastness. 3, can put the hot melt adhesive melts tested on tensile strength, tensile strength of hot melt adhesive is not qualified. Lishui boss complaints as fiber adhesive glue cat agent should be washable and dry cleaning. High purity, low toxicity and excellent weather resistance. Determine the oil-water ratio of 54:46. This has made product performance more good on average. 4, hot melt adhesive, observe whether there is a powdery material after melting, if there are captions powdery material packing, adhesive performance is poor. General coating concentration control in 20% 16-30%, viscosity It is advisable to 20 seconds. A bridge near Paris in 1963, for the first time using epoxy adhesive instead of mortar will split the parts together. Lishui boss glue complaints
