Glue glue contact hefei in hefei Germany Germany contact, therefore, over the past 20 years, this kind of pressure sensitive adhesive is developing very rapidly, and have replaced the dominance of natural rubber pressure-sensitive adhesive.
Water-based glue to use plastic containers, do not use metal containers, otherwise it will affect the glue of resistance to yellowing coefficient.
Hefei German glue contact but high dosage of emulsifier and will reduce the resistance to water of pressure sensitive adhesive and sizing the bubble too much, influence the construction performance.
Water-based glue because volatilizes slower, must add 5% of waterborne curing agent, and mixing 5 -
8 minutes, mix evenly, add the curing agent of glue must be finished within 4 hours, do not use the next day.
Hefei Germany contact the glue glue 6 according to the weight of the brackets than add hardener (
Today hardener added amount is accurate right amount, will affect the early stages of the water-based glue then force and heat resistance;
All landowners with pneumatic stirrer, set of mixing time, under the 300 ∽ 500 RPM speed, stirring for 10 minutes.
Search the public number: WPU -
88 China adhesive platform 8 water-borne pressure sensitive adhesive: stick on the tag is not enough, or early attachment is weak;
Vacuum suction plastic: positioning surface bubble, and the early strength is low;
Paper packaging glue: glue machine after become warped outlet, need to bale or weight.
3 acid ester emulsion pressure sensitive adhesive, preparation, to choose the appropriate soft and hard monomers and dosage, the soft and hard monomer ratio, appropriate to pressure sensitive adhesive bonding performance and cohesion strength coordination and balance, but for pressure sensitive adhesive, is also important to the choice of the functional monomer, it can increase the cohesion of the pressure sensitive adhesive, improved adhesion
with the substrate, and provides further crosslinking active group.
In the 50 - water-based glue drying temperature
3-60 ℃, drying time
About 5 minutes.
Type hot melt adhesive with stable performance, high utilization rate of raw materials, production speed, high yield, 13, equipment cover an area of an area small, and the advantages of small investment of other major acrylic epoxy resin adhesive products silicone acrylic acid with acrylic acid, methyl acrylate, ethyl acrylate and acrylic acid
Ethyl caproic ester copolymer emulsion, such as for electrostatic flocking, flocking adhesive, its fast and feel good.
Water-based glue cannot add oil curing agent, otherwise easy to cause death glue or glue agglomerate, cannot use.
Hefei Germany contact glue sealing glue for all kinds of polishing, polishing, pressure light, PP compound such as PET, PP transparent box, adhesive film, non-woven products, box packaging, food packaging, cigarette packaging, furniture edge banding tetra beverage packaging, assembly, electronic industry, automobile interior trim seal, headlights, windshield assembly, etc. )
, non-woven pads, diapers, diapers, insoles, disposable supplies, paper coating composite trademark, label double-sided adhesive tape, glue plate, flypaper, wooden floor and carpet glue, bandages, medical, color box packaging, carton packaging with breathable tape glue, back adhesive to stick material such as the cingulate has strong adhesive force;
Good thermal stability, no impurities, good operation;
Aluminum foil sealing characteristics of the hot melt adhesive unique water resistant, waterproof.
The selection of hot melt adhesive: although some hot melt adhesive at the time of operation will be some smell, but is completely disappeared after curing, so the hot melt adhesive is safe, can be used in electrical parts of adhesive.
To thin and uniform, water-based glue coating is too thick, after drying, can clearly see the underlying material, if see is the white layer and the brush glue is too thick.
Smell, especially is faulty, people would think is unsafe, so the food and drink beer manufacturer of hot melt adhesive were put forward such as no smell, no smell of glue lets the user feel safe, rest assured, the steadfast.
1, in cleaning up pur polyurethane hot-melt adhesive machine, you must first make the hot melt adhesive plate away from the pur hot melt glue barrel and pur polyurethane hot melt adhesive glue barrel with pur hot-melt adhesive machine, after the hot dish out should be in keeping the lift cylinder under the condition of internal pressure, cut off all the power.
