摘要: A green ceramic composition and a green ceramic body. The green composition and the body formed therefrom have sufficiently high wet strength to prevent formation of defects due to differential flow. The composition does not include calcined clays and comprises hydrated clays, cordierite precursors such as alumina, talc, and silica, and at least one binder. The binder can be present at a level that ranges from 3 wt % up to 10 wt %. A method of making a cordierite green body is also described.

摘要: A twin-screw extruder includes a barrel including a pair of chambers in communication with each other and a discharge port, and an extrusion molding die coupled with respect to the discharge port of the barrel. First and second screw sets are rotatably mounted at least partially within respective ones of the pair of chambers. The first and second screw sets each include a raker blade segment at the discharge port of the barrel that includes at least one flight element with a plurality of serrations extending therethrough. Each of the first and second screw sets also include a lobed kneading segment at the discharge port of the barrel that includes at least one flight element. One of the raker blade segment and the lobed kneading segment is located downstream from another of the raker blade segment and lobed kneading segment. A method of using the twin-screw extruder is also provided.
