Sanming authorization how hot melt adhesive
sanming authorized hot melt adhesive [
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.
Usually volatile substances smell, the smell of heavy metals and other inorganic small.
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.
3, 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.
(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.
Product selection sanming authorization hot melt adhesive how these components by oxidation reduction reaction generated has triggered activity of free radicals.
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.
Sanming authorization about hot melt adhesive shall be conducted according to GB/T 2792.
Water soluble with its functional and environmental protection, and the price is low, will be the future direction of coating.
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.
Sanming authorization about hot melt glue smell is the inherent nature of the material, is one of the important features, material can be measured.
Products with good flexibility, folding, no crack viscosity 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.
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.
Sanming authorization about hot melt adhesive 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.
Sanming authorization about hot melt glue a bisulfite persulfate initiator system, for example, you can through the following reaction generates free radicals: 1.
180 ° peel strength test of the jinan lincom mechanical and electrical technology co. , LTD. (XLW series intelligent electronic relay testing machine
