Abstract

FIELD: production of cardboard. SUBSTANCE: method for production of cardboard by wet technique includes preparation of pulp from fibrous raw material, and binding agent is added to fibers prior to preparation of pulp. Binding agent may be water- soluble which is precipitated and bonded with fibers after acidification. Acidification may be effected during preparation of pulp or prior to it and also prior to adding of binding agent. Binding agent may be added to fibers in the line of pumping from defibrator for production of fibers from fibrous material or may be added before defibrator. EFFECT: higher efficiency.

В способ изготовления картона по мокрому методу масса готовится из волокон, получаемых из волокнистого сырья, а связующее добавляется перед обезвоживанием и прессованием. Способ отличается добавлением связующего к волокнам перед приготовлением массы. Связующее может быть водорастворимым связующим, которое осаждается и скрепляется с волокнами при подкислении. Подкисление может производиться вместе с приготовлением массы или перед ним, а также перед добавлением связующего. Связующее может добавляться к волокнам в линии прокачки от дефибратора для производства волокон из волокнистого сырья или может добавляться перед дефибратором.In the wet method of making cardboard, the mass is prepared from fibers obtained from fibrous raw materials, and the binder is added before dehydration and pressing. The method is characterized by adding a binder to the fibers before preparing the mass. The binder may be a water-soluble binder that is deposited and bonded to the fibers upon acidification. The acidification can be carried out together with the preparation of the mass or in front of him, as well as before adding the binder. A binder may be added to the fibers in the pumping line from the defibrator to produce fibers from the fibrous feed, or may be added before the defibrator.
