Zhanjiang whole series of PUR glue zhanjiang whole series of PUR glue of complaint [ 5] Applicable to BOPP film/printing, PET laser machine/products combined with technical indicators of the note packaging and storage pressure sensitive adhesive can be divided into crosslinked type and the crosslinking type pressure sensitive adhesive. Specifically, PUR hot melt adhesive moisture curing principle is as follows: 4. Water-based glue can not more than 5% of the water against, but to fully mix, or glue layer will effect the stalemate. PUR hot melt adhesive, the adhesive heating molten fluid, coated in glued base material surface, the two glued laminating, colloid at the beginning of cooling rapidly generating viscous force positioning effects ( Physical curing) ; The colloid and the moisture in the air or glued trace moisture of base material continues to function, chemical crosslinking reaction, chain extender ( Chemical curing) 。 After the crosslinking reaction polymer with high cohesion, once cured, then show special waterproof, high resistance to chemical corrosion resistance and weatherability. Crosslinking type pressure sensitive adhesive with good bonding strength, particularly suitable for making permanent pressure-sensitive labels. Is corrosive and has a flexible products, can be felt a lot of base material, in a wider temperature range still has very good performance, and resistant to most chemicals and various climate environment. Hot melt glue gun is frequently used tool, especially when decorating a room. Commonly used in material coating purposes. Have precise effect of open circuit, a variety of nozzle, can satisfy different requirements, the unique design of filter for cleaning and other characteristics, widely used. The innovation provides a simple and effective method of keep the taste and quality. A variety of usage of hot melt adhesive, the life of a hidden artifact hangers skid would clothes? Phone line fault is not willing to throw? The blade naked too? The closet door shutting too big? Now the life need a glue gun can be all done! Don't let hot melt glue gun idle, let it go and live to Duan Junzi glue. Epoxy resin polyurethane type: polyurethane sealant is mostly one-component, good cohesiveness and extensibility. The zhanjiang whole series of PUR adhesive complaints second fracture a black material floolwing do big products. Screen printing ink is a bit thick, and in addition to dry, color can't own curing down, need check equipment, and the curing time is can change with the thickness of the ink. Raw materials and shuikou resolution: up from color to distinguish the material floolwing products used blond, black larger scale. Into the glue guns opened the package, in the packing of the hot melt glue guns tend to have a little support, the small bracket installation in gun two holes on the surface of the whole. With bracket live hot melt glue gun, so will not spoil the table. Antioxidant hardness is 78 - 82, 65 - 75 furniture USES hot melt adhesive is a kind of special to the man-made plank paste adhesive, it is a kind of environmental protection, solvent-free thermoplastic rubber. Zhanjiang whole series of PUR glue complaints after 12, changing the PUR polyurethane hot melt adhesive, must wait for PUR hot melt adhesive machine heating at least 20 minutes before start the pump and motor, such as immediately start the pump and motor can cause polyurethane gear pump damage, reduce the service life of PUR hot melt glue machine.
