Paste. Paste preparation made by the pulp and additives, Backpack Flags of which the slurry should have good structural viscosity and effect. When roller pressure or profit pressure, viscosity becomes smaller relative increase in the permeability of the paste; release the pressure, but also to restore the original viscosity does not affect the fineness of the amount of, so that was easy to .
Other components. Other ingredients, additives, drying agents, to improve the of fitness.
and b. Foaming ink. This foam ink rely on the foaming agent gasification of foam purpose. This ink is a foaming agent dissolved in the liquid polyvinyl chloride resin is made. When the ink is heated, Backpack Flags the blowing agent gasification, the ink layer to the formation of numerous tiny pores, graphic foam raised.
Foaming ink formulations:
Dibasic aluminum phosphate
Amount of pigment (coloring)
Fully grinding the above ingredients, dubbed a paste resin, and by adding an appropriate amount of solvent dilution.
PVC resin. PVC resin is a vinyl chloride by the polymerization of polymers by Emulsion polymerization into a paste resin used as a link to material in the foam ink. Backpack Flags
Calcium carbonate. Calcium carbonate is a white crystal or powder, used as a filler in the foam ink.
Phthalate Lee ester. Dioctyl phthalate is a colorless transparent oily liquid. Used as plasticizers, foaming ink and has good resistance to cold and less volatile. Such plasticizers can increase the plasticity and fluidity of the molding of the PVC resin processing.
Dibasic phosphate of aluminum. Dibasic aluminum phosphate as a stabilizer of PVC resin in the long-term high fever gradual decomposition of the escape of hydrogen chloride gas, will make the resin to continue to break down. Therefore need to add the stabilizer, the absorption of hydrogen chloride gas, and prevent the decomposition of the resin.
Azo-bis-ammonium formate. Azo-bis-ammonium formate is a lemon-yellow crystals. Used as blowing agents in foam ink. Its decomposition temperature in air for 195 ~ 210 ° C in plastic in the decomposition temperature of 155 ~ 210 ° C, gas evolution from 190 to 220 ml / g, precipitation nitrogen and solid residues of oxalic acid amine decomposition. This blowing agent is not soluble in common solvents and plasticizers, but very easily dispersed in the polymer.
Pigments. The main role of the pigment is to make the foam ink coloring, mainly titanium blue, chrome yellow, carbon black, titanium white, magenta, phthalocyanine blue, etc., Backpack Flags as needed quantitative addition. Paint to go through the grinding, mixing, filtering matched to link compound, requiring more detailed the better.
Foam equipment. Foam equipment screen equipment and baking (Pressing machine) equipment.
a. Foam can be ordinary screen equipment, there is no special foam machine.
