Abstract
The invention discloses a kind of dedusting filtrate dressing liquid, as mass fraction, following components is included：Ptfe emulsion 10%~20%, silicone oil emulsion 2%~8%, waterproofing agent of organosilicon 2%~8%, antioxidant 0.2%~0.4%, water-base epoxy resin 1%~3%, silane coupler 3%~10%, nanoscale TiO24%, nonionic penetrant 0.5%~2%, surplus is water.The preparation method and application of above-mentioned dedusting filtrate dressing liquid are also disclosed.Filtrate after above-mentioned dressing liquid processing has excellent water proofing property, preferably film forming, so as to improve the anti-oxidant, corrosion-resistant of filtrate, grease proofing water repellent, antistatic, the performance of anti-condensation paste bag, while extension filtrate service life, improves Nomex media filtration efficiency.
Description
Technical field
The present invention relates to a kind of dedusting filtrate processing technology field, a kind of dedusting filtrate dressing liquid, its system are more particularly to
Preparation Method and application.
Background technology
With rise of the bag-type dusting in dedusting industry, filter bag as sack cleaner core component, to various multiple
The applicability of general labourer's condition also will be improved increasingly.With growing, the master occurred during filter bag use of filter materials selection technology
Want problem to become " condensation paste bag " from " broken bag ", the main cause of " condensation paste bag " be in denitrating system because of the escaping of ammonia phenomenon shape
Into ammonium hydrogen sulfate (ABS) attach on filter bag surface so that the pressure difference in whole deduster remains high, add and use factory
The cost output of family.
The filtrate production later stage needs to be post-processed with dressing liquid, the post processing mode that most filter bag producers use at this stage
For polytetrafluoroethylene (PTFE) (PTFE) dressing liquid impregnation process or the anti-oil processing of water repellent.Polytetrafluoroethylene (PTFE) dressing liquid impregnation process is i.e. with poly-
The processing of tetrafluoroethene emulsion, because of the characteristic that polytetrafluoroethylene (PTFE) is non-sticky after processing, it is difficult to continuous film is formed in fiber surface, because
This improves for the high temperature resistant of filtrate, high humidity, resistance to oxidation burn into acid and alkali corrosion performance, but DeGrain.And
The anti-oil processing of water repellent generally uses fluorine system waterproofing agent, enables to filtrate to have certain water and oil-resistant after processing, for filter
The Anti-dew effect of material be better than polytetrafluoroethylene (PTFE) dressing liquid impregnation process, but water-proofing treatment do not increase filtrate high temperature resistant,
The performances such as resistance to oxidation burn into acid and alkali corrosion.
At present, with the raising of environmental protection standard, continuous improvement of the producer for filter bag performance requirement, both routines are used
Post processing mode can not fully meet the demand of client.The fluorine system waterproofing agent used in the anti-oil processing of water repellent is in acidity, polytetrafluoro
Vac emulsion is in alkalescence, if both to be used in mixed way to the effect by filtrate waterproof is lost.
The content of the invention
The technical problems to be solved by the invention are the provision of a kind of with excellent water proofing property, preferably film forming
Dedusting filtrate dressing liquid, preparation method and the usage.
The present invention is to solve above-mentioned technical problem by the following technical programs：An aspect of of the present present invention provides a kind of dedusting
Filtrate dressing liquid, as mass fraction, it includes following components：
