Description
(54) СПОСОБ ОБРАБОТКИ ЗАПОЛНИТЕЛЯ ЛЕГКОГО БЕТОНА(54) METHOD FOR TREATING LIGHT CONCRETE FILLER
Изобретение относитс к промышленности стронтельных материалов и может быть использовано при изготовлении легких бетонов.The invention relates to the stronghold industry and can be used in the manufacture of lightweight concrete.
Известен способ получени запогжйтел дл легкого бетона путем обработки гранул иенополистарола известковым молоком с последующей гепловой обработкой при 100-150° С в течение 10-20 мин 1.A known method for preparing lightweight concrete was obtained by treating granules of ienopolistarol with lime milk followed by heating at 100-150 ° C for 10-20 minutes 1.
Недостатком известного способа вл етс гнила механическа прочность покрыта и самих фанул пенополистирола после окончани обработки .The disadvantage of this method is that the mechanical strength of the foam is covered and the fan of the expanded polystyrene itself after the end of the treatment.
Известен также способ обработки пенополистирола высокомолекул рным соединением, заключающийс в том, что гранулы обрабатываютс в ультразвуковом поле с опудриванием их минеральным порошком в псевдоожиженном слое 2. Данный способ вл етс наиболее близким к изобретению по технической сущности и достигаемому результату .There is also known a method of treating expanded polystyrene with a high-molecular compound, which means that the granules are treated in an ultrasonic field with dusting them with mineral powder in a fluidized bed 2. This method is the closest to the invention in its technical nature and the result achieved.
Недостатком известного способа вл етс усложненна технологи обработки гранул и недостаточно высока их прочность.The disadvantage of this method is the complicated processing technology of granules and their strength is not high enough.
Целью изобретени вл етс интенсификаци процесса обработки и повышение прочности гранул.The aim of the invention is to intensify the process and increase the strength of the granules.
Достигаетс поставленна цель тем, что опудривание минеральным порошком осуществл ют напылением под давлением, а терг.5Ообработку производ т высокочастотным нагревом с частотой 15-25 МГЦ при 90-110°Св течеш1е 10-20 глик.The goal is achieved in that the dusting with mineral powder is carried out by spraying under pressure, and the terg. 5 The treatment is carried out with high-frequency heating with a frequency of 15-25 MHz at 90-110 ° C.
Выбранный прием опудризаки шгн ральным порошком под давлением после покрыти высокомолекул рным соеданением благодар более глубокому проникновению минерального порошка в пленку позвол ет получить прочное покрытие без значительного увеличени объемного веса гранул.The selected intake of opudrizzi granular powder under pressure after coating with a high molecular weight compound due to deeper penetration of the mineral powder into the film allows a durable coating to be obtained without significantly increasing the bulk weight of the granules.
Обработка токами высокой частоты дает возможность довспенивать гранулы, которые привод тс в термопластичное cocioHiaie благодар наличию температуры вьш1е разм гчени полистирола снаружи и BHjTpi . В результате вспучивани гранул и происход щих структурных изменений высокомолекул рное соединение и минеральньшProcessing with high frequency currents makes it possible to add to the granules, which are brought into thermoplastic cocioHiaie due to the presence of temperature of softening of polystyrene outside and BHjTpi. As a result of the expansion of the granules and the structural changes taking place, the high molecular weight compound and mineral
порошок проникают в наружные слои пенополистирола .powder penetrate the outer layers of polystyrene foam.
Тепловую обработку осуществл ют по всему объему гранул пенополистирола с помощью высокочастотного электрического пол , что ускор етHeat treatment is carried out over the entire volume of expanded polystyrene granules using a high-frequency electric field, which accelerates
