Abstract
Relate to the Self-broken decontamination liquid that radioactive pollutant removes decontamination Material Field, the described soiling solution that disappears is made up of in mass ratio following component: organic-silicon-modified resin 40 ~ 60, silicon sol 10 ~ 20, ethanol 3 ~ 6; Be difficult to after the described soiling solution that disappears effectively can solve existing pollution clean-up material filming peel off, not easily reclaim and can produce a large amount of waste liquid and the low difficult problem of operating efficiency, thus be highly suitable for controlling the structure such as room, passage wall radioactive contamination dust and removing operation.
Description
[technical field]
The present invention relates to radioactive pollutant and remove decontamination Material Field, especially relating to a kind of Self-broken decontamination liquid for removing radioactive contamination dust.
[background technology]
Known, along with continually developing and application of new forms of energy, also day by day perfect about the applicable technology of core, although the development and utilization of nuclear energy brings huge economic benefit and social benefit to the mankind, its radwaste produced in application process brings threat also to the living environment of the mankind, at present, polymer pressed material is mainly comprised both at home and abroad for removing the alpha-contamination removing material of channel wall, dry remover, decontaminant, peelable film insulating covering agent and chemical gel/foam decontaminating agent etc., wherein, because peelable paint can be applied in pollutent surface by peelable film insulating covering agent, and pollutent is taken away by simply peelling off film body after drying forms film, therefore, in large-scale engineering decontamination, especially in the process of the Radioactive decontamination to a large amount of equipment and building structure, application peelable film insulating covering agent just becomes a kind of ideal method, but, find in long-term practical application, because the sagging homogeneity of peelable film insulating covering agent is poor, and generally its film body formed in vertical walls can be not easy to reclaim because crossing thin, therefore, existing peelable film insulating covering agent has certain deficiency when removing vertical walls radioactive contamination dust, simultaneously, other several classes remove materials when removing the pollution of vertical walls also in various degree have the shortcoming that task difficulty is large, workmen's open-assembly time is long, soil removal efficiency is not high and waste liquid amount is large, namely these are removed materials and are also not suitable for for carrying out removing operation to the radioactive contamination dust of vertical walls.
[summary of the invention]
In order to overcome the deficiency in background technology, the invention discloses a kind of Self-broken decontamination liquid effectively can removing vertical walls radioactive contamination dust.
For achieving the above object, the present invention adopts following technical scheme:
A kind of Self-broken decontamination liquid, the described soiling solution that disappears is made up of in mass ratio following component: organic-silicon-modified resin 40 ~ 60, silicon sol 10 ~ 20, ethanol 3 ~ 6; Namely the described soiling solution that disappears is made after stirring 0.5h after said components mixes in normal temperature environment.
Further, the described soiling solution that disappears is made up of in mass ratio following component: organic-silicon-modified resin 50, silicon sol 15, ethanol 5; Namely the described soiling solution that disappears is made after stirring 0.5h after said components mixes in normal temperature environment.
Further, described organic-silicon-modified resin is self-drying type solvent-borne type silicone resin or self-drying aqueous silicone resin.
Further, described self-drying type solvent-borne type silicone resin is JF-2033 type.
Further, described self-drying aqueous silicone resin is JF-2061 type.
Further, described disappear soiling solution when applying by corresponding spray appliance according to 2kg/m
2consumption be sprayed at wall, or cover spraying at twice.
Owing to adopting technical scheme as above, the present invention has following beneficial effect:
Self-broken decontamination liquid of the present invention can be synthesized under normal temperature environment, and synthesis technique is simple, and cost is lower, the described soiling solution that disappears not only has quick-drying and film characteristic easy to crack, but also effectively can improve the homogeneity generating film and the stability improving storage, namely it can to concrete, glass, the radioactive dust of general wall paint wall carries out efficient adsorption, cracked solid-state cleavage block can also be formed after rapid drying simultaneously, and reach the cohesive strength obviously reducing cleavage block and wall, or even the object of self falling, therefore, be difficult to after the described soiling solution that disappears not only efficiently solves existing pollution clean-up material filming peel off, not easily reclaim and can produce a large amount of waste liquid and the low difficult problem of operating efficiency, but also be highly suitable for room, the structure wall radioactive contamination dust such as passage carry out controlling and removing operation.
[embodiment]
Can explain the present invention in more detail by the following examples, disclose object of the present invention and be intended to protect all changes and improvements in the scope of the invention, the present invention is not limited to the following examples:
Described Self-broken decontamination liquid is made up of in mass ratio following component: organic-silicon-modified resin 40 ~ 60, silicon sol 10 ~ 20 and ethanol 3 ~ 6; Wherein, organic-silicon-modified resin is filmogen, and it has quick-drying and film characteristic easy to crack, possesses autoclase cracking performance for making the described soiling solution that disappears; Silicon sol is performance improvement additives, and it can play the effect improving and be coated with film uniformity and improve storage stability; And ethanol uses as solvent, for adjusting viscosity and dry, cracked speed, namely reach to disappear described in the raising thermal adaptability of soiling solution and the object of rate of drying; As required, described organic-silicon-modified resin can adopt self-drying type solvent-borne type silicone resin, such as JF-2033 type or self-drying aqueous silicone resin, such as JF-2061 type;
Just make after stirring 0.5h after said components mixes in normal temperature environment and can be in liquid state, dynamic viscosity lower than 2000mPas in the temperature range of-30 ~ 50 DEG C, the described Self-broken decontamination liquid that normal temperature sealed storage validity period is greater than 1 year; The described soiling solution that disappears utilizes corresponding spraying equipment according to 2kg/m
2consumption once spray in the ventilated environment of-30 ~ 50 DEG C, or after covering is sprayed at the vertical walls such as concrete, glass, general wall paint wall being stained with radioactive dust pollution at twice, can also there is caking at 6 hours inner dryings cracked, reach the cohesive strength of obviously reduction fragment and wall simultaneously or make fragment automatically from the surperficial object come off of wall; The described soiling solution that disappears can will pollute adsorbing powder dust, be embedded in formed solid-state fragment in film forming drying process, thus effectively control flying away of pollution dust, and fragment come off or use relevant device to reclaim process in by pollution clean-up, confirm according to many experiments, the described soiling solution surface contamination clearance rate that disappears can reach more than 85%.
Part not in the detailed description of the invention is prior art, therefore the present invention is not described in detail.
