Description
(54) ШИХТА ДЛЯ ИЗГОТСеЛЕНИЯ СТРОИТЕЛЬНЫХ МАТЕРИАЛОВ тельной деструкции. Органические компоненты окисл ютс и удал ютс из системы . Остающийс в системе неорганичес кий фосфат натри образует в продукте до полнительные количества высокотемпера турного кле - полифосфата натри , что способствует упрочнению издели . Дл получени состава шихты берут три смеси ингредиентов, содержащие, кажда , %: кремнезем - 72, полифосфат ; натри 1,5; вода - остальное и отличающиес друг от друга содержанием 7 8 полиэфира, равным в каждой смеси последовательно , % : 1,0; 1,5;3,О. Полученные составы формуютс в кубики 2х2х2см и обжигаютс при бОО-вОСЯс. Полученные при формовании шихты массы имеют хорошие формовочные и пластические свойства, сохран ют без деформации приданную форму а при раскатывании практически не имеют адгезии к рукам и металлу. Свойства полученных изделий в зависимости от количества полиэфира прёд ставлены ниже.(54) CHARGE FOR PRODUCTION OF CONSTRUCTION MATERIALS of body destruction. The organic components are oxidized and removed from the system. The inorganic sodium phosphate remaining in the system forms additional quantities of high-temperature sodium polyphosphate adhesive in the product, which contributes to the strengthening of the product. To obtain the composition of the mixture, three mixtures of ingredients are taken, each containing,%: silica - 72, polyphosphate; rub 1.5; water - the rest and differing from each other by the content of 7 8 polyester, equal in each mixture in series,%: 1.0; 1.5; 3, O. The resulting formulations are molded into 2 x 2 x 2 cm cubes and calcined with PSO. The masses obtained during the molding of the mixture have good molding and plastic properties, retain the given shape without deformation, and when they are rolled out they practically have no adhesion to hands and metal. The properties of the obtained products, depending on the amount of polyester, are listed below.
