How do you make your adhesive?
Water based adhesives are mainly dry, solid or bonded by absorbing moisture through the surface. A solid in an adhesiveStarch, moisture absorption in line gel paste. The bonding time is from a few seconds to about one minute. Moisture gradually increasedAmbient air and paper fiber absorption. This traditional way of adhesives is generally used for corrugated cardboard production lines, immediatelyProduce a firm bond effect.
In order to achieve satisfactory bonding effect, borax must be added so that the raw starch can be absorbed during heating and all can be absorbedWater; produce the proper viscosity and toughness of gelatinize starch; play a role in preventing buffer, caustic sodaUnder the lowest gelatinization temperature make part of the expansion of starch.
In order to achieve satisfactory bonding effect, a slightly viscous suspension should be added to the starch and water emulsionsWith the pre gelatinized starch. This suspension can cause starch to float in water and prevent it from settlingOn the top roller and forming a suitable thickness of film on the roll; adjust the viscosity so as to make the paper fiber moist properlyInitial adhesion; to ensure that the starch molecules are surrounded by a large amount of moisture, so that the starch can expand maximally when heatedTo be completely gelling; adding caustic soda to adjust and control the starch gelatinization temperature, until the minimum.
The starch binder is actually a raw additive, which is pumped from a pump to a corrugating machine and then coated on a corrugated peak. When theIn the state of being raw, there is no stickiness, and only when it is heated to a certain temperature on the paste line will it become a kind of toughnessAdhesive.
