Abstract
The present invention relates to a modifier for stainless steel fibers, which mainly comprises the following ingredients: 1 of silicone oil, 1.5 to 2.5 of ethyl acetate and 1.5 to 2.5 of polytetrafluoroethylene. While in use, the modifier is diluted to dilute solutions with the concentration of 30% to 40% by water; then, stainless steel fibers are put in the dilute solutions to be dipped for 40 to 80 minutes; finally, the stainless steel fibers are baked at the temperature of 100 DEG C to 150 DEG C, and a mesh can be laid. The modifier of the present invention can effectively reduce the roughness of the surface of the stainless steel fibers and greatly enhance the uniformity of forming nets; the present invention can realize effects on forming nets that the deviation g/m2 of single weight is reduced to at most 3% from the common deviation g/m2 of at least 10%; the yield of products is enhanced to more than 95% from the original yield of less than 70%.
Description
Technical field
The present invention relates to a kind of mineral compound, is a kind of fluorochemical specifically.
Background technology
The stainless steel felt is to develop the product innovation that emerges in recent years, commonly used does filtering material, is widely used in the environmental protection facility such as sewage disposal, has performances such as well acidproof, alkaline-resisting, high temperature resistant.The stainless steel felt is that the Stainless Steel Wire with diameter 1.7mm is drawn into diameter ￠≤25 μ m, and lapping is made.Stainless Steel Wire surface in drawing process becomes coarse, and coarse micron order Stainless Steel Fibre is when felt, and winding, brittle failure mutually easily between fiber causes fiber to become net inhomogeneous, directly influenced the qualification rate of fibrefelt and the quality of fibrefelt.Prior art does not still solve the effective ways of Stainless Steel Fibre surface smoothness.
Summary of the invention
The purpose of this invention is to provide a kind of Chemicals that improve the Stainless Steel Fibre surface smoothness.
The present invention is a kind of Stainless Steel Fibre properties-correcting agent, and this properties-correcting agent mainly contains silicone oil, ethyl lactate, three kinds of compositions of tetrafluoroethylene, and proportioning is therebetween, silicone oil: ethyl lactate: tetrafluoroethylene=1: 1.5～2.5: 1.5～2.5.Silicone oil is abbreviated as " MD
nM "; Ethyl lactate, molecular formula are C
5H
10O
3, structural formula is CH
3CH (OH) COOC
2H
5Tetrafluoroethylene claims special fluorine logical sequence again.Properties-correcting agent of the present invention is to use like this: during use, earlier this properties-correcting agent is diluted with water to concentration and is 30%～40% dilute solution, stir, Stainless Steel Fibre is placed on soaked in this dilute solution 40～80 minutes then, 100 ℃～150 ℃ oven dry, get final product lapping again.Properties-correcting agent of the present invention can effectively reduce the surfaceness of Stainless Steel Fibre, has improved fiber homogeneity into the net greatly, and it becomes net effect to reach: substance deviation (g/m
2) by common 〉=10%, be reduced to≤3%; The yield rate of product, is brought up to more than 95% below 70% by original; This properties-correcting agent is at 400 ℃～600 ℃ of temperature and air pressure 1.0 * 10
-2Under the Pa, can volatilize, carbon-free residual, thus guaranteed fiber homogeneity into the net.
Embodiment
Narrate two embodiment below:
Embodiment 1, prepares 50 kilograms of Stainless Steel Fibre properties-correcting agent
Get: 10 kilograms of silicone oil, 15 kilograms of ethyl lactates, 25 kilograms of tetrafluoroethylene.The three is put together, stir.During use, it is 30% dilute solution that this properties-correcting agent is diluted with water to concentration, stirs, and Stainless Steel Fibre is placed in this dilute solution soaked 80 minutes then, 100 ℃ of oven dry down, gets final product lapping again.
Embodiment 2, prepare 50 kilograms of Stainless Steel Fibre properties-correcting agent
Get: 10 kilograms of silicone oil, 25 kilograms of ethyl lactates, 15 kilograms of tetrafluoroethylene.The three is put together, stir.During use, this properties-correcting agent is diluted with water to concentration becomes 40% dilute solution, stir, Stainless Steel Fibre is placed in this dilute solution soaked 40 minutes then, 150 ℃ of oven dry down, get final product lapping again.
