СПОСОБ ПОЛУЧЕНИЯ НАНОЧАСТИЦ ИЗ БИОПОЛИМЕРА

FIELD: chemistry. ^ SUBSTANCE: in the present method, biopolymer starting material and a plasticiser are fed into the feeding zone of an extruder having an auger configuration such that the biopolymer starting material, particularly starch, in the extruder undergoes processing by shearing forces, and a cross-linking agent is fed into the extruder on the process scheme downstream the feeding zone. The method is characterised by output higher than or equal to 1.0 metric ton of the product per hour. The biopolymer starting material and plasticiser are preferably fed into the feeding zone separately. The extruder in the feeding zone can have single-turn elements. Temperature in the intermediate section of the extruder is not higher than 100C. Configuration of the auger can include two or more sealing sections for water vapour. Shearing forces in the first section of the extruder can be greater than shearing forces in the neighbouring second section of the extruder lying on the process scheme downstream the first section. Water can be fed into the post-reaction section lying after the position in which the cross-linking reaction has finished in order to improve operational characteristics of the head. ^ EFFECT: method enables to obtain cross-linked nanoparticles of a uniform size, having high molecular weight and also enables to manipulate molecular weight of a protective colloid. ^ 38 cl, 3 dwg, 2 tbl, 10 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 457 223 (13) C2 (51) МПК C08L 3/02 (2006.01) C08B 30/00 (2006.01) B29C 47/36 (2006.01) B82B 3/00 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21)(22) Заявка: 2009109258/05, 14.08.2007 (24) Дата начала отсчета срока действия патента: 14.08.2007 (73) Патентообладатель(и): ЭКОСИНТЕТИКС ЛТД.

A method of manufacturing foamed polystyrene balls

A method of continuously manufacturing foamed polystyrene balls includes heating two flows of molten vinyl aromatic polymer 15, 16 to within 25 degrees of an expanding agentâ s critical temperature. The expanding agent is then added to one at a supercritical pressure and the flows are mixed. This mixture can then be extruded through holes in a cylindrical die 37 which are provided with knives to separate the extrusion into granules. A nozzle 13 directs a liquid jet at the die and an inlet 14 feeding a gas to the cutting chamber prevents it flooding. This process ideally produces almost spherical granules having a density less than 50g/l with most of the cavities being unlinked.

Angles of the channels inclination increase as they move from the central channel with zero inclination angle. External surface of the press-tool with outlet holes of the channels is made as a convex segment of a sphere, angles of axes inclination of cylindrical parts of the channels differ from axes inclination angles of converging intake parts of the channels and together they increase as the channels move from the central channel with zero inclination angles of both axes. EFFECT: invention provides higher quality of manufactured products by grain-size distribution, density, mechanical strength and porosity, higher mean efficiency by 2-6 %, as well as reduced by 1-3 % mass and energy losses due to reducing the number of forced shutdowns of the press when loosing stability of the forming process. 1 cl, 10 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (51) МПК B29B 9/00 (13) 2 600 763 C2 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ 2014116044/05, 22.04.2014 (24) Дата начала отсчета срока действия патента: 22.04.2014 (43) Дата публикации заявки: 27.10.2015 Бюл. № 30 (45) Опубликовано: 27.10.2016 Бюл. № 30 2 6 0 0 7 6 ...
