Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for cleaning a vinyl greenhouse used for cultivating plants or the like.

(Prior Art) The outer surface of a vinyl greenhouse is soiled with dirt, sand, etc., and the inner surface of a greenhouse that is heated by a boiler or the like is soiled with soot.

As described above, when the vinyl of a greenhouse becomes soiled, the transmittance of sunlight decreases, affecting the growth of plants, causing problems such as the occurrence of diseases and a decrease in yield.

For this reason, it has been conventional practice to regularly wash the vinyl in greenhouses to remove dirt adhering to the surface.

The conventional cleaning method is to make a cleaning solution by diluting a detergent containing a citric acid ester activator and a mineral solvent, etc. with water, spraying this cleaning solution on the vinyl with a power sprayer, and then spraying it with water using a high-pressure washer. A method of spraying and washing with water is known.

(Problem to be Solved by the Invention) However, in this conventional cleaning method, the main purpose is to decompose dirt by the chemical action of chemicals in detergents, so after spraying the cleaning liquid, the chemicals act to remove dirt. There was a problem in terms of workability, as it took a long time to disassemble and it was not possible to perform the next washing operation consecutively.
Also, even though the dirt is broken down by the chemical action of chemicals,
It is not effective in removing dirt stuck to vinyl,
The reality is that there is almost no improvement in cleaning effectiveness.

(Means for Solving the Problems) The present invention was invented to solve the above-mentioned conventional problems, and its purpose is to remove vinyl by physical polishing with an abrasive material. The purpose of the present invention is to provide a method for cleaning a vinyl greenhouse that removes dirt.

In order to achieve this object, the present invention has a structure in which a polishing liquid made by mixing a powdered abrasive material with water is sprayed onto the vinyl of the greenhouse, and then the vinyl greenhouse is washed with water.

(Function) Therefore, in the cleaning method of the present invention, since the abrasive liquid made by mixing powdered abrasive material with water is jetted toward the vinyl, the abrasive material in the polishing liquid stains the vinyl due to the force of the jet. can be scraped off.

After that, washing with water will wash away dirt particles and residues of the abrasive that adhered to the vinyl, so the vinyl surface can be thoroughly cleaned. The operation can be carried out continuously following the polishing liquid jetting operation.

(Example) The present invention will be explained in detail below.

First, powdered calcium carbide with a particle roughness of 80 mesh is used as the abrasive, and this abrasive is poured into water and mixed well to prepare a polishing liquid. In the examples, in addition to the abrasive, a conventionally used detergent is also mixed.

In this case, the mixing ratio of abrasive material, water, and detergent is 90Q of water.
In contrast, 2400 g of abrasive material and 0.50 g of detergent were mixed well so that the abrasive material and detergent were evenly dispersed in water.

Next, the polishing liquid prepared as described above is sprayed onto the vinyl surface of the greenhouse using a power sprayer or a high-pressure washer.

In this case, the injection pressure is 35 kg/aI, and the injection is performed at the same location twice, from top to bottom and then from bottom to top, while moving sequentially in the lateral direction.

Next, after spraying the polishing liquid onto the vinyl surface as described above, water is sprayed onto the polished vinyl surface using a power sprayer, etc. to eliminate dirt particles adhering to the vinyl and polishing. The cleaning process is completed by rinsing off the remaining materials and detergent.

In this case, the jetting pressure of the water can be lower than the jetting pressure of the polishing liquid described above, and may be 20 kg/cJ.

Therefore, in the cleaning method of this embodiment, since a polishing liquid mixed with a powdered abrasive is sprayed onto the vinyl, the dirt can be removed by a physical polishing operation of scraping off the dirt with the abrasive, and the dirt can be removed from the vinyl surface. It can be cleaned so well that it becomes glossy.

In addition, since dirt can be removed directly by spraying the polishing liquid, washing with water can be carried out immediately after spraying the polishing liquid, eliminating wasted time such as waiting. Work time can be shortened.

In addition, in the example, since a detergent is mixed in the polishing liquid, this detergent can also have a chemical decomposition effect on dirt, making it possible to perform even more effective cleaning. Since the calcium carbide used is also a fertilizer for plants, there is no problem with the polishing solution seeping into the soil due to the washing process.On the contrary, the calcium carbide improves the soil to be suitable for growing plants. It is possible.

Although one embodiment of the present invention has been described above, the specific configuration of the present invention is not limited to the above-described embodiment, and even if there are design changes within the scope of the invention, the present invention included in the technical scope of

For example, as an abrasive material, in addition to calcium carbide, solid materials such as stone, sand, ash, synthetic resin, and light metals can be selected and used, and those that are harmless to the human body and plants can be used. However, the number of meshes is not limited to 80 meshes, and a range of 70 to 120 meshes is considered to be appropriate.

Incidentally, a commercially available household cleanser can also be used as the abrasive.

In addition, regarding the blending ratio of abrasive and water when making a polishing liquid, the abrasive is 1500 to 3500 to 9 Ml of water.
I think it is appropriate to mix within the range of g.

Also, it is not always necessary to mix detergent into the polishing liquid, and the injection pressure of the polishing liquid should be 20 to 5゜kg/
cJ is appropriate, and the jetting pressure of water during rinsing only needs to be enough to wash away dust particles and residues of abrasive material attached to the vinyl, and the jetting pressure of the polishing liquid or less is sufficient.

(Effects of the Invention) As explained above, the vinyl house cleaning method of the present invention uses an abrasive to remove dirt, so the vinyl can be cleaned so thoroughly that the finished product has a glossy finish. The cleaning effect can be improved to an extent that is incomparable to methods using conventional detergents.

In addition, since dirt can be removed directly by jetting the polishing liquid, there is no need to wait for washing with water as in conventional methods, and by making polishing and washing work continuous, work time can be shortened and improved efficiency. The effect is that cleaning work can be carried out.

That is, according to one aspect of the present invention, it is possible to perform the cleaning work efficiently while obtaining a cleaning effect with a clean finish.
