Abstract
Пероксидная целлюлоза (получена делигнификацией реакционной смесью «Н2О2–Н2О–АсОН–АсООН–катализатор») и сульфатная целлюлоза из стеблей пшеничной соломы размолоты до 28–30о ШР. Определены деформационные свойства бумажных отливок: модуль упругости, работа деформации, жесткость и продолжительность релаксации при растяжении и др. При одинаковых механических напряжениях лист из соломенной целлюлозы деформируется в большей степени, чем из древесной, а из сульфатной целлюлозы – в большей степени, чем из пероксидной.
Highlights
–catalyst») and sulfate pulp from stems of wheat straw are beaten to 28–30 SR
Deformation properties of pulp sheet are defined: modulus of elasticity, work of deformation, tension stiffness, relaxation time and others. of Straw pulp sheet is deformed more than wood pulp sheet and from sulphate pulp – under identical mechanical stress
