Bonding strength, two make use of the polyvinyl acetate emulsion modified plastic: this kind of gum is environmental basic safety viscose. fast drying, now to become utilized extensively, however the cost is higher also factors higher middle-and-low quality school, commonly speaking, the higher the price, the strength, the higher the moisture content substance is smaller, high-grade choose this kind of higher top quality rubber packing general.

Through the glue molecular penetration to attain the performance using the bonding treatment of compound now some problems worthy of attraction brought out for the reference. The glue on. system could be the fluid glue evenly coated within membrane layer straight with producing cardstock proper after on damp joint.

To compound images need to own powerful h2o imbibition, one adhesives for water-based gel. Bibulous ability is bad images cannot use this kind of glue compound.

Criterion need to first sample, two for products which include platinum ink prints. Only for platinum ink batch utilized without discoloration reaction ability.

Only to become transparent plastic substance ability proper after lower open, and three complex products in winding the rod. need about time of twenty minutes.

Criterion need to sit twenty-four several hours later. once the need to bump on. products suck.

May be gelatinize too much, 5 tlat matte if seem proper after 4 dozen change out to become warped phenomenon. lead to sub shrinking anxiety consequently of too especially much water, or cardboard high, should really look for to control.

In purchase to stop has the glue polymerization, 6 completely different dealer glue should really not be mixed use. effect on. effect.

Before applying the need to go through the glue action in reduce temperatures is below 10, seven ℃ for that following. If reduce temperatures overall performance is bad, criterion need to adopt h2o bath heating treatment allows the glue temperatures reached 10 ℃ above. So regarding attain the performance of completely glue

Insert movie product top quality inspection techniques

Use every little bit as arms like cleaning clothing that back nonetheless again and forth knead, one knead just before and proper following the inspection: consider proper area on. tear sheets. See plastic substance movie and images in between not withdraw or popping &adhesion firmly that no consider away membrane, product top quality is reliable.

Use hand uncover and tear out, two tear jie inspection: the sample of put movie on plastic substance movie layer. See producing ink coating are commonly completely adhere on membranes or will paper-based tore lousy, if have, make clear complex normal.

Use pass away slicing knife or pressurized, three toppan pressurized inspection: the on. tear sheets to pass away slicing creasing product or toppan printing. See pressurized place to own curly hair white phenomenon. No white phenomenon is marked especially good top quality on..

After 65 ℃ temperatures baking, about 4 heating inspection: the sample to the baking tlat within of the tao. to not think about away a film, no bubbles, not wrinkle make clear on. regular

Membrane coating and producing cardstock are not isolated, 5 immersion test: decided tlat at immersion in h2o sample in about an hour later. A pow camp that joint membrane layer coating solid. coloring box particular glue (framed tile adhesive, snon postformable glue) use commonly appears the problems and solutions, now domestic utilization of corrugated and fits (surface mounted) utilized glue a whole good offer more chaos, comprehensive up about two categories:

Adhesive tape have particular viscous, one use oxidation starch and sodium silicate-bonded plastic: this kind of glue and less expensive prices. So in some low-grade packaging and needs using the dealer even now reduce attraction in use, but merely because this kind of glue powerful alkali, so at situations packaging is yellow, change out to become soft, moisture absorption, brittle, have an effect on the phenomenon of producing ink of happen, should really be washed out affordable glue.
