Longyan authorization laminating adhesive
longyan authorized laminating adhesive of complaint [
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.
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.
If the adhesive is for ordinary families, the quality is not important.
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.
These components by oxidation reduction reaction generated has triggered activity of free radicals.
Usually volatile substances smell, the smell of heavy metals and other inorganic small.
Authorized laminating adhesive products selected longyan complaint hot melt adhesive is a kind of plasticity strong adhesive, and a variety of material and this kind of adhesive bonding, can changes with temperature changes in the nature, after curing adhesion, adhesive strength is big, so many industries can use this kind of adhesive.
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.
Longyan authorization laminating adhesive complaints 9, the pur hot melt glue machine press pressure plate into the plastic bucket, can be appropriate in the daub on the seal of the pressure plate do a small amount of silicone oil lubrication, lubrication, between the pressure plate and rubber barrel to protect the use of the seal ring.
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.
Longyan authorization laminating adhesive clothing with complaints of phthalein amine hot melt adhesive machine reference formulas for the quality of nylon 100 salt, 85 quality of nylon 6 a 'salt, 150 quality of nylon 1010 salt.
Glue dispensing quantity according to the work experience, the size of the adhesive dot diameter should be the half of bonding pad spacing, the size of the adhesive dot diameter should be adhesive dot diameter after patch 1.
Five times, so that can ensure that there is enough glue to bonding elements and avoid excessive glue bonding pad and glue machine dispensing quantity depends on the length of the rotation of the screw pump to decide, practice should be according to the production situation,
Room temperature, glue viscosity, etc. )
Selection of pump rotation time, manufacturing defects which were liable to occur during the following process: glue dot size is unqualified, wire drawing, glue impregnation welding plate, curing strength is bad off so easily, solving the problem of the glue machine should be various technique parameters, overall research to find a solution to the problem.
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.
Longyan laminating adhesive complaints longyan authorized laminating adhesive 3 complaints, checking and adjusting pur don't remove the moisture reactive polyurethane hot melt adhesive any parts of the machine, unless you have enough knowledge of equipment performance.
(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.
