Problems solved by technology

[0003] The products produced by the current process have defects such as poor fiber interweaving structure, uneven hardness, and even fiber clusters on the surface of the product, and uneven density; the thickness is not easy to control, and the production of products with a thickness greater than 60mm is difficult; the volume density fluctuates in a large range; The construction and application effect of the product restrict the development of refractory fiber to high-grade direction

Embodiment Construction

[0011] A vacuum reverse suction molding process for refractory fiber products, including a suction filtration process, in the negative pressure source for suction filtration - mold combination, the negative pressure source is at the bottom, a layer of suction filter mesh is lined in the middle, and a mold is used on it. The suspension slurry is poured into the mold from top to bottom, the solvent water is separated by vacuum suction filtration, the aluminum silicate refractory fiber mixture is absorbed in a mold of a certain shape, and special-shaped products of different shapes can be produced after drying. Features:

[0012] (1) The negative pressure source for suction filtration—in the mold combination, the negative pressure source for vacuum suction filtration is on the liquid surface, and the suction port of the mold is immersed in the feed liquid downward;

[0013] (2) The vacuum suction filter area is a multi-cavity multi-stage distributed arrangement, and the negative ...

Abstract

A vacuum reverse-sucking technology for manufacturing refractory fibrous product features that the mould for manufacturing the said refractory fibrous product is turned over by 180 deg.C to make its sucking mouth deconward, the vacuum sucking region has multiple cavities and multiple segments, and the sucking net is composed of overlapped multiple layers. Its advantages include precise control of volume density, uniform fibre interleaving, high antiflex cracking strength and low thermal conductivity.

Description

technical field [0001] The invention belongs to a refractory fiber product forming process, and relates to a refractory fiber product vacuum suction forming process. It is suitable for the molding process of refractory fiber products. Background technique [0002] When manufacturing refractory fiber products in the prior art, the vacuum forming process is usually adopted. In the negative pressure source for suction filtration-mold combination, the negative pressure source is at the bottom, with a layer of suction filter mesh in the middle, and finally a mold is used; The process is: use aluminum silicate refractory fiber as the main raw material, add a certain amount of binder to make a suspension slurry, pour it into the mold from top to bottom, and separate the solvent water through vacuum suction filtration, and the aluminum silicate refractory The fiber mixture is adsorbed in a mold of a certain shape, and after drying, felts, boards and special-shaped products of diffe...
