TABLE 1
| Experimental group | Amount of dew (g) |
| Example 1 | 2.12±0.11 |
| Example 2 | 2.52±0.02 |
| Example 3 | 2.22±0.15 |
| Comparative example 1 | 1.95±0.12 |
| Comparative example 2 | 29.57±0.04 |
Comparative example 1, example 2, example 3 and comparative example 2 show that: under the same conditions, the weight of the dew generated by adhering the anti-condensation material layer on the surface of the test pipeline is approximately and effectively reduced by 93% compared with the weight of the dew generated by not adhering the anti-condensation material layer, and the anti-condensation effect is good.
Comparative example 1, example 2, example 3 and comparative example 1 show that: the weight of dew generated by adhering the anti-condensation material layer on the surface of the test pipeline is basically the same as that of the dew generated by smearing the existing anti-condensation coating on the surface of the test pipeline, so that the anti-condensation effect similar to that of the existing anti-condensation coating can be achieved by adhering the anti-condensation material layer on the surface of the test pipeline.
However, on the one hand, the adhesion of the anti-condensation material layer to the surface of the object has wider practicability because the anti-condensation material layer is lower in cost and easier to manufacture, and the anti-condensation coating is higher in transportation cost and manufacturing cost.
On the other hand, the anti-condensation material layer is adhered to the surface of the object, so that the anti-condensation material layer has wider practicability, and can be taken down from the surface of the pipeline after dew enters, dried, dewatered, cooled and adhered for use, so that the anti-condensation material layer can be recycled; after the anti-condensation coating is coated and the anti-condensation coating is poor in effect and needs to be replaced, the anti-condensation coating is coated again only after the original anti-condensation coating is scraped off, and in the coating process, the coating material is subjected to secondary coating after being thoroughly dried, so that the coating material is repeatedly coated to the required thickness, and the labor intensity is high.
In conclusion, the anti-condensation material layer in the technical scheme is adhered to the surface of an object through the adhesive layer, the hydrophobic layer is porous in surface and has good air permeability, a certain hollow hydrophobic structure is formed on the surface of the hydrophobic layer, condensation on the surface of the object is not easy to form, and water vapor can be effectively prevented from condensing on the surface of the object; the problem that the surface of an object is easy to dewfall is well solved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
