Fuzhou how all series glue fuzhou whole series of glue (
The main body of pressure sensitive adhesive
composition classification in recent years as the packaging, packaging, office supplies and all kinds of tag demand expands, the demand is becoming more and more big pressure sensitive adhesive.
In the structure of polyurethane resin part introduce hydrophilic group, the emulsification.
3. According to the classification of solvent properties of water-soluble and emulsion adhesives with modified below small make up for the detailed introduce you to the exhibition of products sell like hot cakes.
Acetone method: first made high viscosity polymer, plus acetone viscosity reduction, with a hydrophilic monomer, chain extender, join the water under the high speed stirring, through strong shearing action to disperse in water, emulsion after vacuum distillation recycling solvent is made of PU water dispersion system.
If you are unwell seek immediate extrusion aluminum plating film adhesive editor green products can be safely used in food, drugs, alcohol and tobacco, children's toys packaging processing solids 50 + / - 2% (
5℃/ 3 h)
The machine stability qualified (
3000 r/min, the centrifugal 10 min without precipitation or layered)
In use process should be tightly covered at any time, in case the glue liquid crust, do not entry, can not let children please don't contact with other products mix, not finished product should be kept sealed.
Sealing and isocyanate method: choose the blocking agent of the right to water sensitive side - isocyanate
NCO groups protected, make its loss of activity, add extender chain agent and crosslinking agent, a total of milk made from latex when used by a certain temperature and special catalyst demasking, generating -
NCO terminal base, chain extender to the preparation of waterborne polyurethane
aqueous coating glue with water as solvent or polyurethane acrylate resin through specialized emulsification equipment, emulsion.
Its advantage is: many varieties, environmental protection, low prices.
How about fuzhou all series glue soluble in ethanol, ethyl ether, almost insoluble in water, the water solubility of 0.
When used under the high temperature of 260 ℃, glass, organic silicon laminate or copper - should be adopted
Ptfe composite panels.
Used by the tool before drying of glue can be used warm water to clean.
Now there are a lot of coating is done with water soluble glue, such as general water soluble PA, water soluble PU and leather adhesive, oil wax feeling, the feeling of color paste and other functional material.
Water soluble with its functional and environmental protection, and the price is low, will be the future direction of coating.
Defect is poor film-forming, washing fastness, PU can't stick hot glue.
New product development with hot melt adhesive joint lining cloth furniture sealing side is on fabric surface evenly Xu Bu made of hot melt adhesive.
How about fuzhou all series glue laminated assembly of rigid printed circuit board, can be used with thermoplastic or thermosetting adhesive plastic film bonding together.
