Description

A kind of manufacture craft of middle low temperature filtrate
Technical field
The present invention relates to cleaner field, more particularly to a kind of manufacture craft of middle low temperature filtrate.
Background technology
With the high speed development of national economy, including the industrial mistake including electric power, metallurgy, cement, petrochemical industry, solidification disposal of waste etc. Discharge substantial amounts of smoke-dust in journey, atmosphere pollution (especially PM2.5 pollutions) oneself turn into one and increasingly serious global ask Topic.Coal-burning power plant of electrostatic precipitator Zeng Shi China and the main cleaner in cement plant, but its outlet dust concentration is higher, it is right Working condition requirement is high, and the clearance of fine particle is relatively low.Sack cleaner structure is relatively simple, invest less, it is simple to operate can Lean on, and with collect dust size scope it is wide, filter efficiency is high, do not influenceed by working condition the features such as, just progressively substitute other Poorly efficient dedusting method.
The sizable part of sack cleaner uses needle felt material, belongs to in-depth filtration, by being trapped in filter material Dust particale layer on material is separated, and generally there are the problems such as life-span is low, filtering accuracy is poor, deashing is difficult.For overcome with Upper defect, newest mode is to use coated filter material, and its metal surface filtering, filtering accuracy is high, and its principle is to rely on gluing for surface The film retention dust of conjunction, has the disadvantage to fabricate high cost, and transport installation requirement is high, and exist during use resistance it is big, The problems such as high energy consumption, surface layer film easily fail.Traditional film coating technique is divided into two kinds, and one is that PTFE film is fitted, but Air permenbility one As for 50mm/s or so, and the fastness of film is relatively poor, and two is the foaming coating of PTFE dispersion liquids, is passed through in process of production High temperature sintering temperature is 300-350 DEG C, and energy consumption is big, and the micropore of generation is uneven, and certain pollution, and cost are caused to air It is higher.
In terms of Novel filter material exploitation, some efficient filtrates, such as gradient filter media, composite filtering material have been developed both at home and abroad, And by after surface treatment, being capable of achieving the functions such as grease proofing, waterproof；Or processed by surface coating, thinner particle can be filtered Thing, but the filtrate of this surface coating is expensive, and as filtrate is bad with Film laminated, after losing efficacy of filtrating box etc. can be brought bad Really.Although Some Domestic business research develops the process for treating surface of filtrate, filtrate film coating technique and spun lacing filtering technique etc., Made some progress in economy and applicability, but also needed to further on efficiently control PM2.5 fine particles Research.
The content of the invention
It is an object of the invention to provide a kind of manufacture craft of middle low temperature filtrate, the filtration temperature of middle low temperature filtrate is normal - 120 DEG C of temperature.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：
A kind of manufacture craft of middle low temperature filtrate, including：
(1) terylene needle punched non-woven fabrics, are prepared；
(2) coating paste, is configured, coating paste includes following component, and the total content of component is 100%：
Acrylate, organosilicon, heatproof resin ternary copolymer emulsion：90-95%,
Crosslinking agent：0.5-1%,
Foaming agent：1-2%,
Foam stabilizer：4-6%；
(3), mixed to addition crosslinking agent, foaming agent and stabilizer in ternary copolymer emulsion and complete foaming；To terylene Needle punched non-woven fabrics surface carries out the coating of slurry, bakes.
Preferably, in (3)：Stirred to crosslinking agent, foaming agent and stabilizer is sequentially added in ternary copolymer emulsion Mix, mixing speed is stepped up, mixing speed is that 100-1000 turns/min, and mixing time is 10-20min.
Preferably, in (3)：Slurry is sent into foaming machine by way of negative pressure of vacuum to be foamed, blowing ratio It is 1.5-3.
It is further preferred that described blowing ratio is 2-2.5.
Preferably, in (3)：The speed of coating is 15-20 meters/min.
Preferably, in (3)：The temperature for baking is 135-160 DEG C, and the time for baking is 1-1.5min.
Preferably, after (3)：The filtrate that will be baked carries out pressure bubble treatment with 10-15 meters/min, pressure for 4-8kg.
Preferably, the grammes per square metre of described terylene acupuncture filter material is 500-600g/m2。
Because copolymer emulsion contains silicone ingredients, the microporous barrier that coating is formed in filter material surface, surface is extremely smooth, Ash-removal effect is excellent during use；
Copolymer emulsion is foamed to be coated in filtrate, through after baking and pressing bubble part emulsion glue body embedded fiber enhance the glass of film from Intensity, simultaneously because the effect of additional crosslink agent, the self-strength of formation film is greatly increased during high temperature is baked；
It is different from dispersion liquid, terpolymer, foam produce micropore, be evenly distributed, Kong Jing it is also smaller, and in production process The stability of middle foam is preferable, so as to produce filtrate product stability.
Because above-mentioned technical proposal is used, the present invention has following advantages and effect compared with prior art：
After coating of the present invention filter material surface formed one layer of film with micropore so that improve the heatproof chemical-resistance of filtrate, Hate oily hydrophobic performance, surface effect and deashing property, extend the cleaning cycle and service life of filtrate, be not used in the coating agent Adhesive, is completely dependent on heat treatment, makes melt polymer material, sticks to fiber surface, is prevented effectively from coated filter material film Come off and localized membrane breakage after fill grey phenomenon.
Specific embodiment
With reference to case study on implementation, the invention will be further described：
Embodiment one：
A kind of manufacture craft of middle low temperature filtrate, including：
(1) it is 550g/m, to prepare g weights2Terylene needle punched non-woven fabrics；
(2) coating paste, is configured, coating paste includes following component：
