Description

Известны методы получени  пресснорошков из термореактивных смол и нластиков путем предварительного смешени  их с наполнител ми на различном оборудовании (например , вальцы, бенбери).Methods are known for producing pressor powders from thermosetting resins and lasers by pre-mixing them with fillers on various equipment (for example, rollers, benbury).

После проведени  этой операции смееь может быть получена в виде листов, лент или бесформенных больших кусков в зависимости от примен емого оборудовани . Смесь подвергают охлаждению с последующим проведением дроблени  и просева. Толстые листы, ленты или большие куски охлаждаютс  медленно , при этом качество смеси измен етс  по всей массе неравномерно . При дроблении и просеве происходит потер  материалов и ухудшаютс  санитарные услови  работы.After this operation, the lurking can be obtained in the form of sheets, ribbons or shapeless large pieces, depending on the equipment used. The mixture is subjected to cooling, followed by crushing and sieving. Thick sheets, ribbons or large pieces are cooled slowly, and the quality of the mixture varies unevenly throughout the mass. When crushing and sifting, materials are lost and the sanitary conditions of work deteriorate.

Извеетен также метод получени  пресспорошков в виде гранул, осуществление которого по сравнению с обычными методами требует дополнительной установки к шнекпрессам экструзионных мащин и вызывает значительный расход пара на нагрев смеси до пластического состо ни .The method of obtaining pellets in the form of pellets, which, compared to conventional methods, requires additional installation to screw extruders of extrusion machines and causes a significant consumption of steam for heating the mixture to a plastic state, is also known.

Особенность описываемого изобретени  состоит в том, что с цел12Ю получени  пресспорошков из термореактивных смол и пластиков в виде однородных гранул и устранени  нылевыделени  при дроблении , смесь в гор чем состо нии сразу после смешени  смол илт пластиков с наполнител ми поступает на вальцы, валки которых имеют либо глубокие етрого радиальные рифлени , либо глубокие риски по взаимно-перпендикул рным направлени м (см. чертеж). Предусмотрена также возможность получени  nopoHiKOB на непрерывных вальцах, когда один валок гладкий, а другой имеет рифление с радиальными ребрами.The peculiarity of the described invention consists in the fact that with the whole production of pressurized powders from thermosetting resins and plastics in the form of homogeneous granules and eliminating toxins during crushing, the mixture is in a hot state immediately after mixing the resins or plastics with fillers enters the rollers, the rolls of which have deep, deep radial grooves, or deep risks in mutually perpendicular directions (see drawing). It is also possible to obtain nopoHiKOB on continuous rollers, when one roll is smooth and the other has corrugation with radial ribs.

Полученные тонкие листы подвергают охлаждению, после чего их обрабатывают в галтовочном барабане , при этом получают гранулы правильной формы. Этот метод позвол ет повысить равномерность гвойств пресспорошков, облегчить автоматизацию загрузки в гнезда прессформы, улучшить услови  труда и сократить потери.The obtained thin sheets are subjected to cooling, after which they are treated in a tumbling drum, and granules of the correct shape are obtained. This method allows to increase the uniformity of compactness of compressed powders, to facilitate the automation of loading into the nests of the mold, to improve working conditions and to reduce losses.

Предмет н з о б р с т е и и  Subject matter

Способ гранулировани  иресспорошков на основе термореактивных или термонластичных смол на дробилках валкового типа, отличающийс  тем, что, с целью нолучени  ирессиорошков в виде однородных гранул и устранени  пылевыделени  нри дроблении, пластические материалы прокатывают между валками, снабженными глубокими рифами определеииой конфигурации , после чего полученны листовой материал с отпечатанной геометрией поверхности валков поступает в галтовочный барабан дл  разделени  на гранулы правильной формы.A method of granulating and sprinkling powders based on thermosetting or thermoelastic resins on roll crushers, characterized in that, in order to obtain iress and powders in the form of homogeneous granules and to eliminate dust generation during crushing, plastic materials are rolled between rolls equipped with deep reefs of the defined configuration, after which, after the result, the plastic material is rolled between the rolls provided with deep reefs of the defined configuration, after which the grinding is crushed, after the grinding, after the grinding, then the result of which with the printed surface geometry of the rolls, it enters the tumbling drum for dividing it into granules of regular shape.
