СПОСОБ ИЗГОТОВЛЕНИЯ КЕРАМИЧЕСКИХ ИЗДЕЛИЙ ИЗ НЕПЛАСТИЧНЫХ МАТЕРИАЛОВMETHOD FOR MAKING CERAMIC PRODUCTS FROM NON-PLASTIC MATERIALS
.Ча нлено 8 сент бр 1948 г. за Л 384142/29 в Управление по изобретени м и открыти м Гостехники СССРSeptember 8, 1948, for L 384142/29 to the Office for Inventions and Discoveries of State Machines of the USSR

Известны способы изготовлени керамических изделий из непластичных материалов, при которых дл формовани заготовок порошок материала смешивают с термопластичной органической св зкой и затем отливают нагретую до жидкого состо ни смесь (шликер) в формы . Удаление св зки из отформованной массы заготовки осуществл етс путем нагревани в среде тонкодисперсного материала (засыпки), отсасываюш,его св зку.Methods are known for the manufacture of ceramic products from non-plastic materials, in which the powder of the material is mixed with a thermoplastic organic binder to form the blanks and then the mixture (slip) heated to a liquid state is cast into molds. The removal of the binder from the formed mass of the preform is carried out by heating in the environment of a finely dispersed material (backfill), suctioning off its binder.
В качестве термопластической св зки примен ют: крахмал, казеин , декстрин, воск, парафин, стеарин, церезин и т, п. вещества.The following materials are used as thermoplastic binder: starch, casein, dextrin, wax, paraffin, stearin, ceresin, etc.
Кроме того, известно формование изделий из шликера путем прессовани (штамповки), прот жки через мундштук и вручную с помощью шаблонов.In addition, it is known to form articles from a slip by pressing (stamping), drawing through a mouthpiece and manually using templates.
Вслед за формованием идет процесс сушки полученной заготовки (полуфабриката) и ее обжиг.Following the molding process, the resulting billet (semi-finished product) is dried and fired.
Недостатки известных способов при изготовлении р да деталей (пробирок, тонкостенных станин, деталей сложной формы и т. п.) заключаютс в очень низкой механической прочности полуфабрикатов, в большом количестве брака от деформации и трещин изделий, который по вл етс в процессе сушки и обжига и в невысокой геометрической точности получаемых изделий.The disadvantages of the known methods in the manufacture of a number of parts (test tubes, thin-walled stands, complex-shaped parts, etc.) are in the very low mechanical strength of the semi-finished products, in a large number of defects from deformation and cracks in the products that appear during the drying and firing process. and in the low geometric accuracy of the resulting products.
Надо отметить, что некоторые издели практически невозможно изготовл ть известными способами и все известные способы имеют большой технологический цикл.It should be noted that some products are almost impossible to manufacture by known methods and all known methods have a large technological cycle.
Предложенный способ устран ет эти недостатки и позвол ет приготовл ть тончайшие керамические издели требуемой прочности и формы, которые ранее не производились, за счет того, что при отливке заготовки шликер подают в формы под давлением сжатого воздуха.The proposed method eliminates these drawbacks and permits the preparation of the finest ceramic products of the required strength and shape, which were not previously produced, due to the fact that during the casting of the workpiece, the slip is fed into the molds under compressed air pressure.
:NO i6/b07- 2 Таким образом, предложенный способ, состо щий из сочетани изBecTHi .ix технологических операций- элементов изготовлени керамических изделий, дает новый положительный технический эффект.: NO i6 / b07- 2 Thus, the proposed method, consisting of a combination of the BecTHi. Ix technological operations — elements of the manufacture of ceramic products, yields a new positive technical effect.
Согласно предложенному способу из непластичных материалов совместно со св зкой путем гор чего смешивани при температуре 100- 250° готов т жидкую смесь (шликер), подают ее в стальные формы под давлением сжатого воздуха, удал ют св зку отсасыванием при нагревании заготовки (полуфабриката) в среде тонкодисперсного материала (засыпки) при установленном температурном режиме и обжигают заготовку (полуфабрикат), получа нужные издели .According to the proposed method, a liquid mixture (slip) is prepared together with the binder by hot mixing at a temperature of 100-250 ° C, it is fed into steel molds under compressed air pressure, the binder is removed by suction when the preform (semi-finished product) is heated the environment of the fine material (backfill) at a set temperature and burn the workpiece (semi-finished product), to obtain the desired product.
