Q:How does the pulp solidify? What additives do you need? Curing agents? Or what do you need as binders?

Urea formaldehyde resinUre-aformaldehyde resinsUrea formaldehyde polymer. Also called urea formaldehyde resin. The cross-linking English abbreviation UF. molding, the product is insoluble and infusible thermosetting resin, urea formaldehyde resin cured phenolic resin than the color of light, translucent resistance, weak acid and weak alkali, good insulation properties, excellent wear resistance, low price but, in case of strong acid and strong alkali decomposition, weather resistance is poor. The name Beetle. urea and 37% formaldehyde aqueous solution can be obtained by the polycondensation of linear urea formaldehyde oligomer in catalytic acid or alkali industry, with alkali as catalyst, reaction temperature of about 95, the molar ratio of formaldehyde to urea as 1.2.0, to ensure that the resin curing reaction. The first step to generate and dimethylol urea, then hydroxymethyl amino and soluble resin by further condensation, if by acid catalysis, easy to cause the product to be stored to gel. In neutral condition. The linear UF resin for ammonium chloride Curing agent can be cured at room temperature. The molding powder at 130 to 160 DEG C heat curing accelerators such as zinc sulfate, trimethyl phosphate, two oxalic acid ethyl ester can accelerate the curing process. The urea formaldehyde resin is mainly used in the manufacture of molded plastic manufacturing, daily life products and appliance parts, also can be used as adhesive, paper and fabric sheet the pulp, plywood, decorative board and so on. Because of its light color and easy coloring, products often colorful and magnificent.
