Handan handan PUR glue factory industry PUR glue factory has good flexibility, folding, no crack viscosity of 3000 ~ 5000 mpa.
S health and safety of 20 kg, 50 kg bottled please don't mix with other products, not finished product should be kept sealed.
Join the right amount of antioxidants to prevent premature aging of EVA hot melt adhesive
Because colloid when molten high temperature oxidation decomposition, adding antioxidants can guarantee under the condition of high temperature, bonding performance does not change.
Defect is poor film-forming, washing fastness, PU can't stick hot glue.
In addition to the above several kinds of raw materials can also be according to the difference of temperature, regions with some suitable for cold with the temperature of the thermal dose of cold resistance agent or suitable for tropical temperatures.
Product features look pale yellow viscous emulsion used to maintain good health can be divided into solvent pressure sensitive adhesive, pressure-sensitive adhesive water solution type pressure sensitive adhesive and emulsion pressure sensitive adhesive, hot melt pressure sensitive adhesive and rolling pressure sensitive adhesive, etc. Five types.
To use points: can be divided into filter hot melt adhesive, automated packaging hot melt adhesive, car interior with hot melt adhesive, hot melt adhesive label, adhesive tape, hot melt glue, hot melt adhesive, etc.
Product selection PUR glue factory oxidation - handan industry
Reduction system is made up of two or more components.
Usually volatile substances smell, the smell of heavy metals and other inorganic small.
A, the color of the glue is supposed to have the difference.
If being itself to the color no special requirements, then it is recommended to use yellow hot melt adhesive, generally speaking, yellow hot melt adhesive is better than white sticky.
Handan industry PUR glue factory according to the provisions of GB/T 2792.
(4) from the cleaning fluid plastic brush, must use clean cloth to wipe dry rear can be used to besmear to brush glue;
Hard monomers such as methyl methacrylate, these homopolymer Tg is higher, can enhance the cohesion strength of pressure sensitive adhesive, with the increase of the hard monomers, the viscosity increase of the pressure sensitive adhesive peel strength increases, the early viscous force will be reduced.
Second, by then surface treatment.
Hot melt adhesive surface treatment to be then there is no other adhesive is so strict, but was then content on the surface of the dust, oil pollution also should do the appropriate processing, hot melt adhesive can give full play to the functions of glue.
Handan industry PUR glue factory three, homework time.
Homework is an important characteristic of hot melt adhesive quickly.
Hot melt adhesive homework time generally in 15 seconds, with modern production mode -
Assembly line is widely used, shorter operation time requirements for hot melt adhesive, such as books binding and speaker manufacturing of hot melt adhesive work time requirements for 5 seconds.
Handan industry PUR hot melt adhesive glue factory clothing with poly phthalein amine machine reference formulation for the quality of nylon 100 salt, 85 quality of nylon 6 a 'salt, 150 quality of nylon 1010 salt.
(3) found plastic brush with agglomerate, gel, use boiling water to remove immediately 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.
