Guiyang boss food-grade plastic like guiyang boss food-grade plastic how von sticker glue is the use of advanced equipment and new mature formula, by the scientific development of polymer emulsion. Characteristics (1) water-based glue with water as solvent, drying process, there will be no VOC emissions, thus water-based glue is environmental friendly products; Because do not use organic solvent, and because the range of the cost of crude oil prices rise is much smaller than solvent-based adhesive, relative to the solvent adhesive, water-based adhesive has cost advantage; (1) the warehouse should be managed by accepted the professional training of personnel; (2) the initial force: water-based glue with water as solvent, the adhesive must be in the water fully evaporated, the resin particles together, each other can be reflected, the slower performance in solvent adhesive viscosity, thus early water-based adhesive force are usually more weak than solvent-based adhesive; (2) the deposit interval should keep a certain distance interval, ensure warehouse air convection; Initial adhesion by pressure sensitive adhesive under less pressure on the base material fast 'wetting' formed by the bond strength, mainly determined by the chain of activity, only when the chain of activity is very strong, can with the rough surface of the substrate to form a good wetting, and contact with the substrate molecules at the molecular level, can be produced by the interaction between molecules enough bonding strength. 1. Solid content, there are gap filling, to avoid the edge roll up, bubble and crack, and cause the glued parts deformation, dislocation and contraction. Because there was no solvent, lumber moisture content is not change, no fire and poisoning. Because the viscosity test medium pressure sensitive adhesive is cohesive failure ( Will leave a residue glue) , so the viscous mainly reflects the cohesion strength of rubber. 2. Adhesive, coating and adhesive between several seconds, however, saw the head and trimming can be finished in 24 seconds, do not need drying time, can be used for continuous, wood adhesive production line automation, improve the production efficiency, save the cost factory. Smell six standard: 1 without peculiar smell; 2 a slight odor; 3 have a taste, but do not stimulate; 4 a stimulating smell; 5 strong pungent odor; 6 can't stand the smell. 3. Widely used for bonding a variety of materials. Guiyang boss how is food grade glue 5, used the occasion of pur polyurethane hot melt adhesive machine should guarantee the rapid flow of air. (2) the initial force: water-based glue with water as solvent, the adhesive must be in the water fully evaporated, the resin particles together, each other can be reflected, the slower performance in solvent adhesive viscosity, thus early water-based adhesive force are usually more weak than solvent-based adhesive; (2) the deposit interval should keep a certain distance interval, ensure warehouse air convection; (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; Peel strength is respectively from a standard base material at a constant rate and Angle on the stripping down the force needed. 4. Can be several times of adhesive, coating on the wood hot melt adhesive, do not meet the requirements for cooling solidification, can be reheated for secondary bonding. Guiyang boss how is food grade rubber pressure-sensitive adhesive are generally not used directly in glued content of adhesive, pressure sensitive adhesive is made through a variety of material of pressure sensitive adhesive products ( Duct tape and adhesive label) 。 Textile guiyang boss how food-grade plastic analysis of each peak, discuss its composition [ 8] 。 Construction is convenient, the equipment cover an area of an area small, save manpower, and can be sprayed, roller coating, coating, dots, lines, and so on. Hot melt adhesive are textiles, especially using much more of a kind of adhesive, garment processing is widely used for non-woven fabrics, carpet seams, cloth lining, zippers, etc. Of the adhesive. Applied to the hot melt adhesive on the textile industry should have good bonding strength, excellent flexibility, resistance to water to wash/dry cleaning. In addition, because of the fabric in the process of shape, mostly through steam treatment, therefore, requires adhesive has the characteristics of high temperature steam its softening point requirements higher than 115 ℃, the third must have the appropriate degree of crystallinity, in order to improve the thermal stability of the adhesive. With polyamide as the substrate, for example, the minimum content of 45% ( The mass fraction) 。 For softness excellent fabrics, insist on hot melt adhesive has lower viscosity. Product has good initial adhesion, stick relay is strong, fast drying speed, adhesive film good toughness and resistance to acid and alkali, antifreeze, flame retardant, non-toxic tasteless, does not affect human body health, safe environmental protection considerations note package and store PET aluminum plating film adhesive editing machine good adaptability, high peel strength, at the beginning of stick with a viscous fluid supply technical indicators brush or roller coating glue can be used in the process of should be tightly cover at any time, to prevent liquid cement crust, do not entry, can not let the child contact pressure sensitive adhesive and the meaning of pressure sensitive adhesive products have ten several ways
