Toughened alumina ceramic overlapping curved pipe of high-performance zirconium oxide and its production

Abstract

The invention is concerned with high capability zirconia particulates toughened alumina ceramic net wave tube and its production method. According to the requirement of net wave tube to wear resistance, intension and toughness of stuff, and thinking about to reduce cost, select zirconia particulates toughened alumina ceramic stuff to produce the ceramic net wave tube and get ZrO2 toughened Al2O3 composite ceramic. Its weight and cost is lower than zirconia ceramic and its wear resistance, intension and toughness are better than alumina ceramic coating. The three point bending intension is larger or equal to 500 to 600Mpa, the rupture toughness is larger or equal to 6.8 to 10MPa.m1 / 2, and the rigidity is larger or equal to 1200 to 1500Gma. The process is producing ZrO2 toughened Al2O3 composite ceramic powder, milling, preparing high solid ceramic plasm by mixing round (adding dispersant, adjusting the value of pH), gel to pour the module, dryness, sinter, rubbing and getting ceramic net wave tube with high precision.

Description

technical field [0001] The invention belongs to a new material component structure for a color packaging carton printing die-cutting machine and a manufacturing method thereof, in particular to an anilox tube and a manufacturing method thereof, which are mainly used in a color packaging carton printing die-cutting machine. Background technique [0002] The anilox tube is a key component in the color packaging carton printing die-cutting machine. Each printing die-cutting machine needs 4 anilox tubes, and the anilox tube is a consumable product. Therefore, the market of reticulated pipe is large and the prospect is very broad. At present, the traditional metal reticulated pipe is mainly based on the traditional metal reticulated pipe. The traditional metal reticulated pipe has poor wear resistance and short service life, usually only about 10 days, so it cannot meet the requirements of today's high-speed color packaging carton printing die-cutting machine.

At present, the traditional metal reticulated pipe is mainly based on the traditional metal reticulated pipe. The traditional metal reticulated pipe has poor wear resistance and short service life, usually only about 10 days, so it cannot meet the requirements of today's high-speed color packaging carton printing die-cutting machine. Require

Recently, foreign countries (such as the United States, Japan, and Europe) have improved the traditional metal reticulated pipe, that is, the aluminum oxide ceramic coating is used to prepare the reticulated pipe on the surface of the metal pipe. Although the wear resistance of this method has been improved to a certain extent Although the wear resistance of the ceramic coated reticulated pipe is higher than that of the metal reticulated pipe, due to the difference in thermal expansion coefficient and elastic modulus between the alumina ceramic coating and the base material, the existing internal stress will cause a small Cracks will also affect the printing quality and shorten the service life, generally one to two months

Moreover, China itself cannot produce this kind of ceramic-coated reticulated pipe, almost all of which are imported from abroad, and the price is expensive, with an average price of 7,000 yuan / piece
