Abstract
The invention discloses an ECR/PTFE fiber blended yarn treatment method. The ECR/PTFE fiber blended yarn is prepared by blending of ECR fiber and PTFE fiber. The ECR/PTFE fiber blended yarn is characterized in that: at the end of blending, the ECR/PTFE fiber blended yarn needs impregnation pressing treatment by a surface chemical treatment agent, which contains a PTFE emulsion, hydroxyl silicone oil, a silane coupling agent A151 and superfine graphite. Compared with the prior art, the method provided by the invention has the following advantages that: the ECR/PTFE fiber blended yarn prepared by the scheme has high acid resistance and high filtering performance, is a high cost performance filter base cloth fiber, has acid resistance far higher than that of GF/PTFE fiber and service life longer than that of GF/PTFE fiber, and the two materials have equivalent price. The ECR/PTFE fiber blended yarn is a material with good acid resistance at present, and can be applied to the field of high acidity and high temperature flue gas dust removal and filtration.
Description
Technical field
The present invention relates to fume treatment technical field, in particular a kind of ECR/PTFE fiber blend yarn processing method.
Background technology
China's environmental complex degradating trend is contained not yet at all, and environmental problem has become one of principal element threatening health, public safety and social stability.China is coal-fired production and consumption first big country, and light coal fired power generation discharges flue dust every year and reaches 5,000,000 tons, and its flue dust is mostly below PM10 fine dust, and industrial dust occupies critical positions in atmosphere pollution.And it is high containing SO in this flue gas
2, NO
xwith high acid gas such as HC, wherein SO
2discharge capacity accounts for national total release more than 50%.Coal-fired peracidity flue gas ash removal is adopted at present mostly to the high temperature blended yarns such as PPS (polyphenylene sulfide), PTFE (polytetrafluoroethylene (PTFE)) and GF (glass fibre).PPS valency is high, and not resistance to oxidation, high temperature resistant grade is constant, and PTFE intensity is low, poor dimensional stability, and also valency is high, be difficult to be used alone, GF acid resistance difference (especially E glass), so require with GF price suitable, and the good inorfil of acid resistance replaces GF and PTFE fiber composite to prepare the object that high-performance blended yarn is the present invention.
ECR is resistance to chemical attack alkali-free glass, and it is the floride-free glass fibre without boron of a kind of alkali-free, has the acid resistance of extra-heavy, resistance to water, anticorrosion stress-resistant and short-term alkali resistance, also has good electric property simultaneously.Without the raw material that boracic is fluorine-containing in ECR glass formula, eliminate fluorine, boron from source to the pollution of environment, manufacture process Air Contamination is reduced to minimum level.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of ECR/PTFE fiber blend yarn processing method.
The present invention is achieved by the following technical solutions: a kind of ECR/PTFE fiber blend yarn processing method, ECR/PTFE fiber blend yarn is made through blending by ECR fiber and PTFE fiber, it is characterized in that: ECR/PTFE fiber blend yarn is after blending completes, need to carry out dipping pressure through surface chemical treatment agent and prick process, in surface chemical treatment agent, comprise PTFE emulsion, hydroxy silicon oil, silane coupling A 151 and superfine graphite.
As further improvement of these options, the superfine graphite of the PTFE emulsion containing 25 ~ 45% weight ratios in surface chemical treatment agent, the hydroxy silicon oil of 3 ~ 10% weight ratios, silane coupling A 151 and 5 ~ 15% weight ratio of 0.5 ~ 2.5% weight ratio.
As further improvement of these options, in blended yarn, the proportioning of ECR fiber and PTFE fiber is 70/30 ~ 60/40.
As further improvement of these options, ECR fiber adopt weaving fiber size for reinforcemeent produce: fiber filament diameter is 6 ~ 9um, yam count be 100 ?150TEX.
As further improvement of these options, PTFE long fiber selected by PTFE fiber, and line density is 400 ~ 450deu, and tensile strength is 13 ~ 19N.
The present invention has the following advantages compared to existing technology: the ECR/PTFE fiber blend yarn produced by this programme process possesses highly-acidproof energy, the high performance-price ratio blended yarn fiber of high filtration performance, its acid resistance is far above GF/PTFE fiber blend yarn, service life, also comparatively GF/PTFE fiber blend yarn was long, and the two price is suitable, be the good a kind of blended yarn of current acid resistance, can be applicable to peracidity high temperature fume dust removal filtration art.
Detailed description of the invention
Elaborate to embodiments of the invention below, the present embodiment is implemented under premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
Embodiment 1
