Traditional Chinese Deinking Agent for Waste Paper Recycling
In short: Small-Scale Chinese Handmade Paper Production: Workshop Formula, Ratios & Method. This entry documents a formula & ratios taken from Chinese practical-technology literature, written for small-scale makers and home producers. The text below is the full English translation of the original Chinese workshop notes, covering materials and quantities, the step-by-step sequence, and the practical cautions recorded in the source. Roughly 9115 words of English technical text, translated and preserved without editing. It is intended for experimental and reference use, not for regulated or commercial certification.
Waste paper regeneration deinking agentIn the past, when regenerating waste paper, the reagents used to separate pulp and ink include caustic soda, sodium silicate and other alkaline reagents, hydrogen peroxide, sodium sulfite and other bleaching agents, as well as deinking agents, such as alkyl benzene sulfonates, alkyl sulfonates, α-olefin sulfonates, higher fatty acid salts and other anionic surfactants, and higher alcohols, alkylphenols, polyethylene glycol ethers and esters of fatty acids and other non-ionic surfactants.However, due to the recent increase in the types of waste paper, the diversification of ink ingredients, and the advanced printing technology, previous deinking agents cannot achieve good deinking effects. Of course, it is more difficult to obtain high-quality recycled paper with high whiteness. Therefore, it has become an urgent task to develop a deinking agent suitable for recycling various waste papers.The present invention has successfully developed a deinking agent with excellent deinking effect.The two compounds used are as follows:RO(C3H6O)1SO3M (Ⅰ)R′O(C2H4O)m(C3H6O)nH (II)When compound (I) is used alone, or when (I) and nonionic surfactant (II) are used together in a certain ratio, and compound (I) …
