Problems solved by technology

[0002] In order to increase the compression resistance of the metal fiber felt in the filter, it is often necessary to add a single-sided or double-sided support net to the outer surface of the metal felt. There is a known metal fiber felt. The support net is formed by sintering with the metal fiber felt. Th

Embodiment Construction

[0009] The present invention will be further described below in conjunction with the drawings.

[0010] figure 1 , figure 2 The metal fiber felt with protective net shown is composed of metal fiber felt 1 and metal protective net 2. The metal fiber felt is fixed in the middle of two layers of metal protective nets, and the surroundings between the metal protective net and the metal fiber felt are bonded The elastic gasket 4 formed by the agent 3.

[0011] The production method is: coat the adhesive 3 on the front and back of the metal fiber felt, and coat the adhesive 3 around the guard net 2, then place the metal guard net and the metal fiber mat in the mold and heat it. Pressure forming, the adhesive can be a rubber type. After coating the metal fiber felt and the protective net around, it is pressed to form an elastic sealing gasket 4 around it, which can prevent liquid leakage.

Abstract

A process for making metal fibre felt with two protecting metal net layers, metal fibre felt between two protecting net layers and elastic seal ribbon adhered to periphery of felt. A technology for preparing it includes such steps as coating the rubber-type adhesive to the edges of metal fibre felt and protecting nets, arranging them in a mould, and hot pressing. Its advantages are high size and shape precision, high pressure tolerance, and simplified sealing structure.

Description

1. Technical Field [0001] The invention relates to a metal fiber felt, in particular to a filter metal fiber felt for man-made fiber solution. 2. Background technology [0002] In order to increase the pressure resistance of the metal fiber felt in the filtration, it is often necessary to add a single-sided or double-sided support net on the outer surface of the metal felt. There is a well-known metal fiber felt. The support net is formed by sintering with the metal fiber felt. The "sandwich" structure can effectively protect the metal felt, but with this method, the wire diameter of the support mesh cannot be too different from the metal fiber wire diameter. The thick wire diameter is not easy to sinter with the metal fiber, which affects the support. The power of the net. 3. Summary of the invention [0003] The purpose of the present invention is to provide a metal fiber felt and a manufacturing method thereof, so that the periphery of the protective net is tightly combined w...
