How do you use the hefei whole series of glue

Hefei how to use the full series of glue hefei how to use the full series of glue von sticker glue is the use of advanced equipment and new mature formula, by the scientific development of polymer emulsion. Characteristics due to the initial adhesive' target='_blank'>adhesion was mainly affected by segment activity, and its viscosity influence mainly by cohesion strength, therefore, it is generally believed that formula soft monomer, low molecular weight, and the width of the existence of the molecular weight distribution can improve the adhesive can tack, hard monomer, crosslinking branched factors will improve adhesive can hold viscous, and exist in stripping experiment, pressure sensitive adhesive peel failure mode shift ( Interface damage or cohesion damage) , therefore, need to consider these factors impact on adhesion force and cohesive 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. (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. 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. 3. Widely used for bonding a variety of materials. Eight hefei how to use the full series of glue, hot melt adhesive and solvent using general safety precautions: suggest using hair roller, to ensure uniform cloth and rubber, unfavorable choose brush and spatula this product already adjust the indicators according to the laminating process, when using, do not add water or other solvents 20 kg, 50 kg bottled product use has good gloss, good heat resistance and freeze resistance, corrosion resistance strong sex solids 40 - 50±2%( 105℃±1. 5℃/ 3 h) Should stir well when using packaging and storage definition 1: use refers to the pressure, it can make adhesive instantly at any glued glue material is bright and clean surface. 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. 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. Hefei whole series of how to use the glue viscosity refers to after cementing, respectively by a certain external force have been destroyed by the continuous shear under the action of time. Textile hefei whole series of how to use the glue, Emulsifier) K12( Sodium dodecyl sulfate) 0. 5 g OP - 10 ( Octyl phenol polyoxyethylene ( 10) Ether) 0. 4 g in the infrared image by above knowable sample and carbonyl peak ( 1700) , hydroxyl ( 3000) And alkyl ( C - near 1200 H bending vibration) The above results show that acrylic acid involved in the reaction. Object of adhesive, bonding and sealing, wide application range, paper, plastic, metal, ceramic and so on all have better stick relay; 1, can under the professional instrument for testing analyzing the composition of hot melt adhesive, so that we can get the accurate data. When pur hot melt adhesive machine use pur glue barrel and melt pressure plate exposure to rapid circulation of air, because of the rapid cooling, will affect the pur hot melt adhesive machine hot melt adhesive flow, but also waste energy.
