Extrusion molding process of pressureless sintered silicon carbide
The invention discloses an extrusion molding process of pressureless sintered silicon carbide, which comprises the following steps: proportionally adding silicon carbide ultrafine powder, a sinteringaid, a dispersing agent, a binder, water and the like into a horizontal ball mill, performing grinding, performing drying by using a spray drying tower to obtain uniformly mixed granules, accurately weighing the granules, and adding the granules into a kneader, adding water according to a certain ratio, performing mixing to obtain extruded pug with certain plasticity, performing vacuum pugging fermentation to ensure that pug particles are in more uniform contact with an additive and the plasticity is stronger, putting the pug into a spiral vacuum extruder, and extruding products with differentlengths and different shapes according to molds with different product sizes. According to the invention, the functions of continuous production, high efficiency and capability of producing large-size tea products are realized.
本发明公开了一种无压烧结碳化硅的挤出成型工艺，将碳化硅超细粉料和助烧剂、分散剂、粘结剂、水等按照比例加入到卧式球磨机内研磨，利用喷雾干燥塔进行干燥处理，得到混合均匀的颗粒料，将颗粒料准确称量投入到捏合机中，按照比例加水，进行混炼即可得到具有一定塑性的挤出泥料，再通过真空练泥醒料，使泥料颗粒与添加剂接触更加均匀塑性更强，将泥料投入螺旋式真空挤出机，根据不同产品尺寸模具即可挤出不同长度不同形状产品，本发明实现了可连续生产，效率高，可生茶大尺寸产品的功能。
