Problems solved by technology

The surface of the stainless steel wire becomes rough during the drawing process. When the rough micron stainless steel fiber is felted, the fibers are easily entangled and brittle, resulting in uneven fiber web formation, which directly affects the qualified rate of the fiber mat and the quality of the fiber mat. the quality of

Embodiment 1

[0006] Embodiment 1, prepare 50 kilograms of stainless steel fiber modifiers

[0007] Take: 10 kg of silicone oil, 15 kg of ethyl lactate, and 25 kg of polytetrafluoroethylene. Put all three together and stir well. When in use, dilute the modifier with water to a dilute solution with a concentration of 30%, stir evenly, then soak the stainless steel fiber in the dilute solution for 80 minutes, and then dry it at 100°C to lay the net.

Embodiment 2

[0008] Embodiment 2, prepare 50 kilograms of stainless steel fiber modifiers

[0009] Take: 10 kg of silicone oil, 25 kg of ethyl lactate, and 15 kg of polytetrafluoroethylene. Put all three together and stir well. When in use, dilute the modifier with water to a concentration of 40% dilute solution, stir evenly, then soak the stainless steel fiber in this dilute solution for 40 minutes, and then dry it at 150°C to lay the net.

Abstract

The present invention relates toa stainless steel fiber modifying agent. It mainly contains three components of silicon oil, ethyl lactate and teflon according to ratio of 1:1.5-2.5:1.5-2.5. When it is used, firstly, said modifying agent can be diluted with water to obtain the dilute solution whose concentration is 30%-40%, then the stainless steel fibre is placed in the diluted solution and socked for 40-80 min., then dried at 100 deg.C-150 deg.C, then the net can be laid. Said invention modifying agent can effectively reduce the surface roughness of stainless steel fibre, and can greatly raise web-forming uniformity.

Description

technical field [0001] The present invention relates to an inorganic compound, specifically a fluoride. Background technique [0002] Stainless steel felt is a new product developed and released in recent years. It is often used as a filter material and widely used in environmental protection facilities such as sewage treatment. It has good acid resistance, alkali resistance, and high temperature resistance. Stainless steel felt is made by drawing stainless steel wire with a diameter of 1.7mm to a diameter of ￠≤25μm, and laying a net. The surface of the stainless steel wire becomes rough during the drawing process. When the rough micron stainless steel fiber is felted, the fibers are easily entangled and brittle, resulting in uneven fiber web formation, which directly affects the qualified rate of the fiber mat and the quality of the fiber mat. the quality of. There is still no effective method to solve the surface finish of stainless steel fibers...
