Ученые из Перми провели успешные испытания полимерных конструкций из раствора с добавлением целлюлозно-бумажных отходов. Добавки позволяют снизить себестоимость производства полимеров из вторсырья, тротуарной плитки и проч на 10%. Специалисты отраслевого исследовательского центра Пермской целлюлозно-бумажной компании (ПЦБК) совместно с лабораторией конструкционных материалов строительного факультета Пермского национального исследовательского политехнического университета (ПНИПУ) проверили промышленные образцы полимерных фитингов и полимерпесчаных плит для тротуаров.
Продукт, получающийся при одном из способов варки целлюлозы — лигносульфонат (ЛСТ) позволил снизить стоимость исходной смеси. Кроме того, в ходе опытов выяснилось, что ЛСТ действует как пластификатор — позволяет раствору чуть дольше оставаться пластичным и лучше заполнять форму.

Следующим этапом станет испытание промышленного образца. В мае запланированы замеры прочности полимерпесчаной плиты без наполнителя для сравнения характеристик.
