No microcapsules on the back of carbonless copy paper. Early microcapsules, are prepared by the microemulsion droplet surface before the organic dye precursor-containing precipitate the water-soluble polymer (e.g., gelatin, gum arabic, and esterified cellulose). Precipitation by pH and temperature control. [1] The microcapsules direct about 3 ~ 8 μm (size depends on the size of the microemulsion droplets). Currently microcapsules, high-carbon paper, through the two-phase interface between an organic polymer prepared (no longer the aforementioned crosslinked polymer precipitated mechanism), carbon-free paper wholesale, this production method is more controllable. Common microcapsules "film" has polyurea, polyamide, phenolic resins and the like. The chemical composition of the raw material starch, pectin, starch cell storage cavity material, not much content, Hainan carbonless paper, soluble in water, there is no effect on the pulp and paper. Usually the ingredients contain little pectin, which is easily decomposed and dissolved in dilute alkali. Plants in the form of pectin in the presence of salt, is considered to be a source of plant ash. Flax and other bast fibers cellmedium mainly pectin, only a small amount of alkaline cooking can be unglued. Tannin, pigment content generally less raw materials without damage, they are susceptible to hot water extraction. But more content should try to draw out beforehand, otherwise the pulp bleaching is not easy to become darker in color.
