0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 1.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; There are two common skinning phenomena: one is the skinning on the surface of the glue in the packaging barrel, the other is in The glue layer on the surface of the rubber disc produces a skin.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; The skin of the box glue in the packaging barrel is crust

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 1) If the temperature is too high when filtering and packaging the glue, it is easy to form a crust in the barrel when the temperature drops. This kind of situation is common in the high temperature in summer, because the glue cools slowly, if the goods require emergency and can not be lowered to a suitable temperature for packaging, this situation is easy to occur.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 2) If the packaged glue is exposed to sunlight, it will also form a skin.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Crust in the surface layer of glue

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 1) When the glue plate has a dead angle (such as a rectangular shape of the glue plate), the glue rarely flows, and the surface glue moisture Will slowly evaporate, forming a film and skinning.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 2) There is hot air blowing directly to the tray in the drying tunnel

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 3) The surface of the foam with more foam is very thin and easy to form a film.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 2.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Foam is also divided into foam in the barrel and foam when gluing

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; foam in the barrel

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; This situation is mainly due to the violent shaking during the transportation process to generate foam, and also more foam after infiltration with more moisture and stirring .

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; When there is more foam when glue is applied, the glue tray will slowly come out

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 1) The glue defoamer fails or is under-metered

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 2) The top roller speed is too high and the glue is stirred too strongly

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 3) The glue level and the top roller are in an inappropriate position. Into a lot of gas.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 4) The viscosity of the glue is too high, and the thicker foam wall is not easy to break.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; There are many foams in the glue box, and the consequences are also as follows:

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 1) affect the speed of compounding (filming speed)

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 2) When a large amount of glue is applied, part of the foam is applied to the film. Road, or enter the drying channel without breaking the bubble, drying and breaking to form empty spots, and after compounding, a phenomenon similar to fish eyes and pin holes occurs.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 3) It is easy to produce glue box skin on the glue plate.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; In the method of dealing with more foam, the common way is to add anti-foaming agent, but it is necessary to pay attention to adding anti-foaming agent The type, quantity and stirring method, if improper operation, it is easy to cause the drop of glue eyes and peeling force.
