УПРУГО-ДЕФОРМАЦИОННОЕ ИЗМЕЛЬЧЕНИЕ ХЛОПКОВОЙ ЦЕЛЛЮЛОЗЫ И ВЛИЯНИЕ СПОСОБА ВОЗДЕЙСТВИЯ НА СТРУКТУРУ И СВОЙСТВ ПОРОШКОВ

Аннотация

Subjects of the inquiry: cellulose, cotton fiber, cotton lint and also the obtained powdered cellulose. Aim of the inquiry: development of elastically-deformation method and device for pulverizing of cellulose materials; obtain of powdered cellulose and also the investigation of it's structure, properties and application. Methods of inquiry: methods of optical and electronic microscopy; IR-, NMR- and KP-spectroscopy, X-ray method; sorbsion and calorimetric investigations. The results achieved and their novelty: for the first time the new method of reducing of cotton cellulose under action of high pressure and shift deformation and also the new installation was constructed providing continuous obtain of thinly- dispersion powder cellulose (UZ patent 1487236). For the first time the methanism of physical destruction of cotton cellulose at elastically - deformation pulverizing was determined. By methods of IR-, NMR-, KP-scopiya, X-ray method and thermodinamical analysis it was determined that elastically-deformation action and shift have brought to decreasing of content of high-regulating parts of cellulose in limits of structure form C-I. Particularities of the milling of cellulose materials were determined and also it was shown that elastically-deformation milling of the natural cellulose have carried out changing of physical structure without conformation changings. Practical value: development and constraction of laboratory and experimental-industrial installations for obtain of thinly - dispersion power cellulose from cotton cellulose. For example scientifically -industrial enterprise «Tegirmon» has developed experienced industrial installation for elastically -deformation pulverizing of cellulose materials with productivity 10 kg/h Degree of embed and economical effectivity: power cellulose obtained by elastically - deformation pulverizing was used as sorbents and ionits, materials of medical purpose, substrats for glucose obtain by ferment hydrolysis, initial source for obtain of sodium salt of carboxymethilcellulose and heliums. Sphere of usage: medicine, pharmaceutics, cosmetics, paper and chemical industries.
