1.31 Окись цинка ; Целлюлозу размальшают в ролле до Степени помола 25-36 ШР. Затем в волок йистую массу ввод т латекс. В послед|ний предварительно ввод т дубовый экстракт (в.виде водного раствора), дисперсию тиурама (или цимата) и окиси цинка. Коагул цию латекса провод т водным раствором хлористого натри с концентрацией, Вес. %: .5 (в начале процесса) и 20 вес. % ;(в конце процесса коагул ции) - до полного осаждени каучука на волокне. I Массы отливают многослойным отли- вом. Затем листы картона выдерьсивают в течение 8 час, прессуют на гидравлическом прессе при удельном давлении 14-15 кгс/см и . сушат при 80-1О5°С в течение 6 час и при 126 С - в тече ние 1 час. Полученный картон имеет еле-1.31 Zinc oxide; Cellulose is crushed in a roll to the degree of grinding 25-36 SR. Then a latex is introduced into the wet mass. In the latter, oak extract is preliminarily introduced (as an aqueous solution), dispersion of thiuram (or cymat) and zinc oxide. The coagulation of the latex is carried out with an aqueous solution of sodium chloride with a concentration, wt. %: .5 (at the beginning of the process) and 20 wt. %; (at the end of the coagulation process) until the rubber is completely deposited on the fiber. I The masses are cast in multilayer cast. Then the sheets of cardboard are extracted for 8 hours, pressed on a hydraulic press with a specific pressure of 14-15 kgf / cm and. dried at 80-1О5 ° С for 6 hours and at 126 С for 1 hour. The resulting cardboard has a
