Abstract
The invention discloses deliquescence-resistant coarse titaniumpowder. The deliquescence-resistant coarse titaniumpowder comprises, by weight, 15-20 parts of a structural aid, 2-10 parts of a hardener, 2-8 parts of a water repellent, 2-6 parts of a stabilizer and 3-60 parts of a crude titaniumpowderraw material. The crude titanium powderraw material comprises a coarse titanium powder main body and nano-SiO2. The invention provides the deliquescence-resistant coarse titanium powder and a preparation method thereof. The SiO2 as a carrier improves the resistance to deliquescence. Through useof polyoxyethylene as a hardener, potassium methylsilicate as a water repellent and sodium carboxymethylcellulose as a stabilizer, the deliquescence-resistant coarse titanium powder has good flexibility and plasticity and has a compact structure. A permanent waterproof membrane is formed on the outer part of coarse titanium powder so that the coarse titanium powder is not easy to deliquesce and deteriorate and can effectively resistcorrosion.
Description
technical field [0001] The invention relates to the technical field of coarse titanium powder, in particular to a deliquescence-resistant coarse titanium powder and a preparation method thereof. Background technique [0002] Titanium powder is a very versatile metal powder. It is an additive for powder metallurgy and alloy materials. At the same time, it is also an important raw material for cermets, surface coating agents, aluminum alloy additives, electric vacuum getters, spraying, and plating. [0003] The catalyst made of titanium powder is easy to cause wear and dust under the scouring action of dust in the flue, especially the top wear is the most prominent, which will cause damage and fracture of the catalyst, and then cause the blockage of the catalyst channel, causing a series of follow-up question. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a deliquescence-resistant coarse ...
