СПОСОБ ПОЛУЧЕНИЯ ТОНКОДИСПЕРСНОГО METHOD OF OBTAINING THIN FINE

4four

Изобретение относитс  к Спбсобу получени  наполнител  дл  пластмасс, резин и других материалов, используемых в химической промышленности и промыплленности строительных материалов.The invention relates to the production of fillers for plastics, rubbers and other materials used in the chemical industry and the production of building materials.

Известен способ получени  наполнителей, в частности мела, путем одновременного помола , сушки и модификации гидрофобизируюп;ими добавками, например жирными кислотами и их сол ми, вводимыми в наполнитель предварительно, до обработки гор чим газом.A known method for producing fillers, in particular chalk, by simultaneous grinding, drying and modification of water-repellent agents, such as with fatty acids and their salts, which are introduced into the filler beforehand, is treated with a hot gas.

Недостаток известного способа - невысока  сыпучесть продукта (10 а/сек).The disadvantage of this method is the low flowability of the product (10 a / sec).

Дл  повышени  сыпучести наполнител  предложено в качестве теплоносител  примен ть газ, содержаш;ий продукты неполного сгорани  топлива, например тонкодисперсную сажу, количество которых составл ет 0,01- 1% от веса газа. Сыпучесть продукта 17 г/сек.To increase the flowability of the filler, it has been proposed to use gas containing coolant, as well as products of incomplete combustion of fuels, such as fine soot, the amount of which is 0.01-1% by weight of the gas, as a heat carrier. Flowability of the product 17 g / sec.

Пример. Природный мел Логовского месторождени  с размером частиц 10 мм и влажностью 10% смешивают в вибросмесителе со стеаратом кальци  и подают в аэрогидрофобизатор (газоструйную мельницу-сушилку). Материал подхватываетс  гор чим газом, который генерируетс  в камерах сгорани , работаюш ,их в режиме неполного сжигани  топлива-автотракторного керосина. Энергоноситель содержит 0,03% продуктов неполногоExample. Natural chalk Logovskogo field with a particle size of 10 mm and a moisture content of 10% is mixed in a vibrating mixer with calcium stearate and served in aerohydrophobicizer (gas-jet mill-dryer). The material is picked up by hot gas, which is generated in the combustion chambers, working in the mode of incomplete combustion of auto-tractor kerosene fuel. Energy contains 0.03% of incomplete products

сгорани  в виде высокодисперсной сажи. При соударении встречных потоков гор чего газа, несущего природный мел, стеарет кальци  и сажу, происходит диспергаци  частиц мела, модификаци  их продуктами неполного сгорани  и стеаратом кальци , а также удаление влаги.Combustion in the form of highly dispersed soot. Upon the collision of counter flows of hot gas carrying natural chalk, calcium stearate and soot, chalk particles are dispersed, modified by products of incomplete combustion and calcium stearate, as well as moisture removal.

Готовый продукт - высушенный гидрофобный порошок, имеющий стальную окраску, осаждаетс  в циклонах и на фильтрах. Полученный таким способом наполнитель характеризуетс  новыщенной сыпучестью и обеспечивает улучшение физико-механических показателей поливинилхлоридных пленок.The finished product, a dried hydrophobic powder having a steel color, is deposited in cyclones and on filters. The filler obtained in this way is characterized by a higher flowability and provides improved physical and mechanical properties of polyvinyl chloride films.

Предмет изобретени Subject invention

Способ получени  тонкодисперсного наполнител , например мела, путем одновременного помола, сушки и модификации исходного материала в высокоскоростных стру х теплоносител - гор чего газа, отличающийс  тем, что, с целью повышени  сыпучести наполнител , в качестве теплоносител  примен ют газ, содержащий продукты неполного сгорани  топлива, например тонкодисперсную сажу, количество которых составл ет 0,01 - 1% от веса газа. НАПОЛНИТЕЛЯA method for producing a finely dispersed filler, such as chalk, by simultaneously grinding, drying and modifying the raw material in high-speed jet of heat carrier — a hot gas, characterized in that, in order to increase the flowability of the filler, gas containing partial combustion products is used as a heat carrier. e.g. fine soot, the amount of which is 0.01-1% by weight of the gas.
