    摘要: A thermal shock resistant and asymmetric honeycomb ceramic wall-flow filter, comprising: an inlet honeycomb ceramic surface and an outlet honeycomb ceramic surface. Inlet channels (1) and outlet channels (2) are provided on both the inlet honeycomb ceramic surface and the outlet honeycomb ceramic surface. The inlet channels (1) are in communication with the outlet channels (2). Outlet ends of the inlet channels (1) and inlet ends of the outlet channels (2) are sealed. An inner diameter of the inlet channel (1) is greater than that of the outlet channel (2). A cross-section of the inlet channel (1) is a square, and is provided with a fillet, or two adjacent edges are connected by two connecting lines, or two adjacent edges are connected by two connecting lines or a circular arc located between the two connecting lines. A cross-section of the outlet channel (2) is a square, and is also provided with a fillet or a chamfer. The filter has good mechanical properties, low back pressure, and excellent thermal shock resistance.

    摘要: A honeycomb structure body, which includes a honeycomb body and a skin layer, the honeycomb body including axially extending channels defined by a porous wall, wherein a radial path of a radial section of the honeycomb body from a central axis to the skin layer consists of a porous wall inner section and a porous wall outer section in sequence, an average wall thickness of inner porous walls provided in the porous wall inner section is smaller than an average wall thickness of outer porous walls provided in the porous wall outer section, and a length of the porous wall inner section in the radial path accounts for 71%-95%. The specific structure of the honeycomb structure body not only increases the strength of the honeycomb structure body, but also ensures good thermal shock resistance and small back pressure.

    摘要: Disclosed are a honeycomb structure body, a honeycomb structure filter and an extrusion molding die for a honeycomb structure body, which belong to the field of vehicle exhaust purification materials. The honeycomb structure body includes a honeycomb body and a skin layer around the honeycomb body, the honeycomb body including axially-extending channels defined by a porous wall, wherein a radial path of a radial section of the honeycomb body from a central axis to the skin layer consists of a porous wall inner section and a porous wall outer section in sequence, an average wall thickness of inner porous walls provided in the porous wall inner section is smaller than an average wall thickness of outer porous walls provided in the porous wall outer section, and a length of the porous wall inner section in the radial path accounts for 71%-95%. The arrangement of the specific structure of the honeycomb structure body of the present application not only increases the strength of the honeycomb structure body, but also ensures good thermal shock resistance and small back pressure of the honeycomb structure body; and the honeycomb structure body of the present application is prepared by integral molding, thereby achieving high production efficiency and low preparation cost.

    摘要: Provided is a high-light transmittance zirconia sintered body, prepared by processing and forming a material for the high-light transmittance zirconia sintered body, and then performing high-temperature sintering in the atmosphere under normal pressure. The material for a high-light transmittance zirconia sintered body is prepared from zirconia powder and α-aluminum oxide as raw materials, wherein the molar percentage of yttrium oxide in the zirconia powder is 4-6%. The high-light transmittance zirconia sintered body can be used for preparing a fixed dental prosthesis. The zirconia sintered body has a grain size of 0.1-0.7 μm, and due to the dispersion and toughening by aluminum oxide, the zirconia sintered body has a higher strength and toughness. Pores in the zirconia powder can be eliminated by adding aluminum oxide. The zirconia sintered body has a higher light transmittance, and the prepared dentures are good in texture, good in jade-like appearance, and closer to the human teeth.
