Description
Известны способы изготовлени массы дл типографских печатных валиков с применением дефицитного и дорогого глицерина; при ЭТОМ примен ема желатино-глицерипова масса имеет недостатки в отношении набухани и сравнительно быстрого усыхани .Methods are known for making pulp for printing presses using scarce and expensive glycerol; at THIS, the gelatin-glyceride mass used has disadvantages with regard to swelling and relatively rapid drying.
Предлагаемый способ позвол ет заменить глицерин техническим триэтаноламином недефицитным и более дешевым материалом.The proposed method allows glycerol to be replaced by technical triethanolamine with a non-deficient and cheaper material.
Сзацн.ость способа заключаетс в ТОМ, ЧТО желатина при повышенной температуре раствор етс в техническом триэтаноламине. Предварительно желатина замачиваетс в течение 12 часов. Триэтаноламии в котле с мешалкой с вод ным обогревом нагреваетс до 70. В подогретый триэтаноламин мелкимиThe essential feature of the process is the fact that gelatin dissolves in technical triethanolamine at elevated temperatures. The gelatin is pre-soaked for 12 hours. The triethanolamia in the stirred water boiler is heated to 70. In the heated triethanolamine, small
порци ми загружаетс замоченна желатина при работающей меп(алке .Soaked gelatin is loaded in portions with mep (alka.
Варка массы производитс при температуре не выше 80 .The pulp is cooked at a temperature no higher than 80.
1 loc.ie полпого растворении желатины в Триэтаноламине производитс упаривание массы до 16-18 /) содержани воды и затем полученна вальимисса фильтруетс .1 loc.ie by the half-dissolving of gelatin in Triethanolamine, evaporation of the mass to 16-18 /) of the water content is carried out and then the resulting valimissa is filtered.
