Перспективы использования хитозана для придания антистатических свойств цементной композиции

Перспективы использования хитозана для придания антистатических свойств цементной композиции

Abstract

Environmental compatibility of construction materials and their impact onto the human organism and the environment are the essential factors to be taken account of in the course of construction. Therefore, natural renewable biological polymers arouse interest. Polysaccharide chitin takes a special position among them. It represents one of the most widely spread biological polymers; it is extracted from 100% renewable materials. It is part of the external skeleton of crustaceans and insects, and it also part of cell walls of mushrooms and algae. Any research of potential materials to be generated from chitin and its derivative chitosan may involve a practical implementation. The research of the antistatic properties followed the introduction of 1% of chitosan into the cement composition. Electrostatic field intensity was measured by Electrostatic Field Intensity Meter ST-01. The electrostatic property of the sample modified by chitosan turned out to be lower than the one of the benchmark sample by 5.6 times. The presence of chitosan in the cement composition makes no impact on strength-related properties of the construction material. The cement composition modified by chitosan may be used in the manufacturing of antistatic self-leveling floors.

Проведены исследования направленные на создание материалов на основе хитина и его производного хитозана имеют практическое значение.Для исследования антистатических свойств в цементную композицию вводился хитозан в количестве 1% к ПЦ. Уровень напряженности электростатического поля измерялся прибором СТ-01 (измеритель напряженности электростатического поля). Рассчитанная электризуемостъ образца, модифицированного хитозаном, оказалась в 5,6 раза ниже электризуемости контрольного образца. Введение хитозана в цементную композицию не повлияло на прочностные характеристики строительного материала.Цементная композиция,модифицированнаяхитозаном, может быть использованна для устройства антистатических наливных полов.
