Abstract
The invention discloses air purifying agent. The air purifying agent is characterized by comprising the following components in percentage by weight: 60%-80% of polyether modified silicone oil and 20%-40% of octaphenyl polyoxyethyiene. Compared with the prior art, the air purifying agent disclosed by the invention has the advantages of good coal dust wetting and dust-removing effects and low cost, and is convenient to use.
Description
Technical field
The invention belongs to dustfall agent, be specifically related to a kind of air purifying preparation that coal dust is had good wetting and depositing dust performance.
Background technology
Coal dust is the coal dust of the fine particle that produces in the coal mining process.Coal dust flies upward contaminated air in the tunnel, easily causes miner's anthracosis, and the serious harm miner's is healthy, is one of the most common occupational.Also can cause coal-dust explosion when coal dust and oxygen concentration reach certain limit and naked light is arranged, its harmfulness is very huge.Therefore, it is particularly important that the depositing dust of coal dust just seems, industrially generally take the measures such as coal-bed flooding, spray sprinkler or available ventilation to come depositing dust, and spray sprinkler have good effect to the control dirt depositing dust of large-scale open scope, therefore is used widely in coal industry field.
The surface tension of water is larger, can not the effective wetting coal dust, and dust-laying effect is poor, and add surface tension and the moistening corner that can make the aqueous solution of surfactant reduce, thus increase solution to the wettability of coal dust.According to coal dust Surface Physical Chemistry character, the multiplex anion surfactant of down-hole atomizing de-dusting and non-ionic surface active agent.According to existing bibliographical information, anionic surfactant is maximum has neopelex (SDBS), lauryl sodium sulfate (SDS) etc., non-ionic surface active agent to use maximum have OP series (as: OP-10) and TX serial (as: TX-100) etc.SDS is insoluble in water, and application is restricted; SDBS is water-soluble also not good, and to the wettability of coal dust far away from non-ionic surface active agent; Though OP series and TX series are soluble in water, particularly can not show wetting and depositing dust performance preferably below critical micelle concentration (CMC) at low concentration, application cost is relatively high.
Summary of the invention
The air purifying preparation that the purpose of this invention is to provide a kind of and depositing dust better performances wetting to coal dust.
For achieving the above object, the present invention is by the following technical solutions:
Technical scheme 1, air purifying preparation of the present invention (cleanser 1), adopt following component and weight percent content:
Polyether modified silicon oil 60～80 %; OPEO (TX-405) 20～40 %.

Technical scheme 2, air purifying preparation of the present invention (cleanser 2), adopt following component and weight percent content:
Polyether modified silicon oil 30～73 %; OPEO (TX-405) 10～36 %; Neopelex (SDBS) 9～50 %.
The preferred content of described component is:
Polyether modified silicon oil 50 %; OPEO (TX-405) 20 %; Neopelex (SDBS) 30 %.
The compound method of air purifying preparation of the present invention: described component is mixed getting final product by described proportioning.
During use, air purifying preparation of the present invention and water are mixed into solution for wetting and atomizing de-dusting.Cleanser 1(or cleanser 2) mass concentration suitable at 0.1～0.7 g/L, wherein best with 0.5～0.7 g/L.Single from wetting and dust-laying effect consideration, be advisable with 0.7 g/L; Consider financial cost and wetting and dust-laying effect, best with 0.5 g/L.
The serviceability temperature scope of air purifying preparation of the present invention: 10～40 ℃.Temperature is decided by this body structure of surfactant for the impact of surfactant wettability, in general, improves temperature and is conducive to improve wettability, and therefore, serviceability temperature is 25～40 ℃ of the bests.
Wetting and the dust-laying effect of air purifying preparation of the present invention sees Table 1 and table 2, can find out, it is wetting and dust-laying effect is all good than existing single component surface activator solution.
Table 1: the wetting effect of various surfactant solutions compares:
| Surfactant | SDBS | TX-100 | Cleanser 1 | Cleanser 2 |
