| titleOfInvention | Process for producing binderless formaldehyde-free fiberboard and coproducing fulvic acid from straw |
| abstract | A process for producing binderless formaldehyde-free fiberboard and coproducing fulvic acid from straw. All-element purification, activation, saccharification and separation are carried out on the non-wood fiber raw material through boiling and defibering to obtain primarily activated lignin, purified and activated fibers, monosaccharides of hemicellulose and non-wood fibers, and fulvic acid. Deep activation is carried out on activated lignin. The binderless formaldehyde-free fiberboard is produced by using sufficiently activated lignin and low-molecular-weight monosaccharides as a hardener and binder. By sufficiently activating the lignin, comprehensive utilization of straw fiber as resources is realized, and the special requirements of binderless formaldehyde-free fiberboard for high-quality fibrous raw material and high-activity lignin are met. The boiled dilute black liquor was subjected to extraction and concentrated to obtain fulvic acid, thereby avoiding pollution caused by pulping and board production. The distilled water obtained by carrying out evaporative concentration on the boiled dilute black liquor is reused. |
