Embodiment 1

[0008] ①, material selection and preparation

[0009] Purchase 1 kg of 75-mesh quartz sand;

[0010] Purchase 1 kg of water glass with a modulus of 2.2;

[0011] Configure 1 kg of water glass solution diluted to 10%.

[0012] ②. Spray the diluted water glass evenly on the quartz sand, and do directional shaking, so that the quartz sand is bonded together under the action of water glass to form a particle shape of a certain size similar to a sphere.

[0013] ③. Aging at 25°C for 24 hours to harden the spherical particles to have a certain strength, or to blow carbon dioxide to solidify the spherical particles to have a certain strength.

[0014] ④. Sieve and store particles of different sizes separately for later use.

Abstract

The invention discloses a filling particle of black foam metal and making method in the black foam metal technical domain, which comprises the following steps: blending sodium silicate and quartz sand to form filling particle; spraying sodium silicate solution with water on the quartz sand evenly; swaying directionally; solidifying under certain temperature or through carbon dioxide to possess certain strength; sieving; preparing the particle with fire resistance and easy dissolution; improving void rate of pore structure of black foam metal evenly.

Description

technical field [0001] The invention belongs to the technical field of producing foamed ferrous metal. In particular, it relates to filler particles used for producing foamed ferrous metals by extrusion infiltration technology and a production method thereof. Background technique [0002] At present, the production of foamed stainless steel and other materials at home and abroad is completed by powder foaming process, but the uniformity and porosity of the internal pore structure of foamed ferrous metal produced by powder foaming process is difficult to control, and the quality is difficult to meet the ideal requirements. Contents of the invention [0003] The purpose of the present invention is: to provide a new technical scheme, to provide a new filler particle for the production of foamed ferrous metal by the extrusion seepage process, which can greatly improve the quality of the produced foamed ferrous metal. [0004] The present invention is realized in the following...
