Description

  The present invention relates to a technique for providing a coating film collecting tool and a coating film collecting method that contribute to anticorrosion coating and anti-aging measures implemented for the maintenance management of steel structures.

  Conventionally, in order to provide a corrosion prevention function for steel structures and building iron parts, lead-tan paints and lead-based anticorrosion paints mainly composed of lead anti-corrosion pigments have been used. However, as lead paint rust-preventing undercoats, JISK5622 (lead red paint), JISK5624 (basic chromate rust-preventing paint), JIS5627 (zinc chromate rust-preventing paint) and JIS5627 (lead Tan zinc chromate anticorrosive paint) was abolished.

Nonetheless, as JIS standards, only JISK5623 (lead oxide rust preventive paint), JISK5625 (cyanamide lead rust preventive paint), and JISK5629 (lead acid calcium rust preventive paint) were used as anticorrosion primer for steel structures. . However, in April 2014, these were also deleted from the JIS standard.
As described above, the anticorrosion undercoat and the middle / top coat mainly composed of lead and chromium pigments have been abolished.

  Among the anti-corrosion coating systems used so far, chlorinated rubber coatings manufactured from 1967 to 1972 are classified as PCB (polycarbonate), which is certified as a hazardous substance. Biphenyl chloride) was added. This anticorrosion coating system using chlorinated rubber paint has been used for many steel structures including road bridges.

  At present, manufacture, use and import of chlorinated rubber-based paints containing PCB are prohibited by relevant laws and regulations. In Japan, in accordance with the Stockholm Convention (POPs Convention), it is required to abolish the use by 2005 and implement appropriate treatment by 40.

  Deterioration of paint film containing PCB, lead, chromium, etc. (hereinafter referred to as “coating film”) is caused by coating changes such as blistering, peeling, and film peeling due to aging and aging of structures. Is generated. In addition, the rust generated on the surface of the steel material causes the deteriorated coating film containing harmful substances to fall off, so that it is necessary to take measures to protect the surrounding environment.

  Most of the methods for dealing with the deterioration of the coating film are limited to repainting by locally removing the coating film. Therefore, a future countermeasure against aging of steel structures is to shift to long-term anticorrosion coating, which is expected to have a long service life. The long-term anti-corrosion repainting can be handled by applying a coating system such as a long-term anti-corrosive primer and a highly weather-resistant top coat, and completely removing the existing coating film containing harmful substances. It is a necessary condition to adjust a clean steel base.

  In recent years, aging of road structures has progressed, and the frequency of repairing, reinforcing, and inspecting structural parts has increased. Moreover, in the repair work by partial or local aging countermeasures, the need for repair work by removing the coating film as a long-term aging countermeasure and changing to a long-term anticorrosion coating system or by repair is increasing.

  Under such circumstances, in the presence of existing coatings containing PCB, lead, and chromium, the ground treatment for repainting and the repair and maintenance work for steel structures including roads should be carried out. become. In order to carry out refurbishment / repair work related to this existing paint film, it is necessary to confirm the presence or absence of harmful substances contained in the waste paint film discharged to the surrounding work environment and to properly store and dispose of the waste paint film. Become. In addition, it is necessary to understand the current situation for the development of safe infrastructure, especially the presence, concentration and type of harmful substances in existing coatings. Therefore, an analytical test for determining whether or not a harmful substance is contained in an existing coating film is essential.

  Depending on the presence / absence, type, and concentration of harmful substances contained in the coating film, the safety measures for repainting and maintenance / renovation work, and the storage and disposal methods for discharged contaminated waste vary. If the contents of toxic substances are not grasped and these operations are carried out, the paint film fragments and paint dust generated at that time will be a health hazard caused by sucking them and the surroundings due to their diffusion. There is concern about environmental pollution. In addition, there is a concern that coating films containing hazardous substances that are discharged may lead to contamination of the living environment if they are not properly treated in accordance with the relevant laws and regulations on industrial waste.

  Therefore, for aging countermeasures and maintenance management of existing steel structures, while confirming the history of the structure and the history of the coating system protecting the steel material, chemical analysis of the specimen collected from the existing coating film, It has become mandatory to evaluate and determine the concentration and type of harmful substances such as lead, chromium and PCB.

  Conventionally, there are various apparatuses and methods for removing a paint film. It is conceivable to use this to collect a coating film for an analytical test. For example, Patent Document 1 includes a heating device that heats and carbonizes a coating film applied to a structure, and a scraping device that scrapes and removes the coating film carbonized by the heating device. Thereby, since the carbonized coating film can be easily peeled off from the structure, it can be easily scraped off and removed. It is said that it has the effect of improving the work environment and working efficiency.

JP 2001-334799 A

However, when analyzing a coating film, safety measures are required to prevent accidents due to scattering, diffusion and suction of the collected coating film, assuming that the coating film contains harmful substances.
The conventional method for collecting coatings requires large-scale and safe temporary equipment such as installation of anti-scattering work to prevent contamination and diffusion of harmful coatings on the temporary equipment. In addition, the amount of industrial waste due to secondary contamination due to harmful paint film adhering to the temporary equipment is large, and the processing time and cost for that are also great.

That is, the conventional method for collecting and collecting a coating film has the following problems to be solved.
1. In order to prevent contamination of the surrounding environment due to diffusion and scattering of existing paint film fragments and dust paint films that occur during paint film collection work, provision of temporary equipment, etc. It is necessary to take measures against scattering.
2. The operation of collecting the coating film is easily influenced by the weather, and the collected coating film may be diffused or washed away by the influence of wind and rain, and the process of collecting the coating film is not stable.
3. In the work environment where temporary equipment and countermeasures against scattering are required, the coated surface for collecting the coating film for analysis becomes wide, and impurities are likely to be mixed during collection of the collected coating film, resulting in an analysis sample of inappropriate quality. .
4. When collecting coatings containing harmful substances, workers must wear safety protective clothing, safety masks such as dust masks, protective gloves, and protective glasses that are compatible with the hazardous substances. Also, in a narrow and sealed work place, measures to prevent health problems due to suction, such as installing equipment such as ventilation, are necessary.
5. Predetermined procedures are required to implement measures against coating scattering such as provision of temporary equipment. In addition, the number of work days including the installation and removal of temporary facilities increases, the range of scattering countermeasures is wide, and the generation of secondary contamination waste due to the adhesion and soaking of paint films containing hazardous substances also increases.
6. To collect and handle coatings containing hazardous substances, specialized technicians with knowledge of coating history, knowledge of safety protective equipment and tools, and practical experience are required.

  Although the removal apparatus and the removal method of the paint film of patent document 1 were shown as a prior art example, they do not solve the above-mentioned problem. In addition, other conventional publications that solve the problem could not be found.

  Therefore, when collecting a coating film for analytical tests, the coating film is collected safely, the coating film is efficiently recovered, impurities are not mixed, and secondary contaminated waste generated during operation is removed. Development of a coating film collecting tool that can be reduced as much as possible, and establishment and popularization of a coating film collecting method using the same are desired.

The coating film 51 is collected by being scraped off from the coating surface 50 and falling and accumulating inside the bag-like body 11. In addition, as a tool for coating film scraping, a cemented carbide blade or other tools can be used.

In the coating film collecting step, the coating film 51 collected inside the bag-like body 11 is collected at one end of the two separation sections 13a and 13b as shown in FIG. The end portion is sealed with an adhesive tape 41 from the outside. Thereafter, the adhesive tape 41 is cut almost from the center, and the coating film 51 is collected.
When collecting the coating film 51, as shown in FIG. 7, the coating film collection bag 30 was attached to the end of the separating part 13a (or 13b) on the collecting side, and then collected at the end. The coating film 51 can be deposited on the coating film collection bag 30. The end portion of the coating film collection bag 30 is sealed with an adhesive tape 31 from the outside, and the adhesive tape 31 is cut from almost the center to collect the coating film 51.

The left and right hands are put into the bag-like body 11. A work glove (work gloves, etc.) is put into the bag 11 from the upper opening / closing part 15. Thereafter, the work gloves (work gloves) are attached to the left and right hands wearing the protective gloves 21a and 21b.

  A coating film scraping operation and a coating film peeling operation are performed by putting a tool for coating film scraping and a coating film peeling agent into and out of the bag-like body 11 from the opening / closing part 15. The coating film 51 is collected by being scraped off from the coating surface 50 and falling and accumulating inside the bag-like body 11.

  In the coating film collecting step, the coating film 51 collected inside the bag-shaped body 11 is formed into a bag shape formed so as to open to the lower side of the bag-shaped body 11 and protrude outwardly as shown in FIG. The collected film is collected in the coated film collecting unit 22. Further, the film is deposited on the coating film collection bag 30 placed outside the opening / closing unit 15 of the coating film collection unit 22. As shown in FIG. 7, the end of the coating film collection bag 30 is sealed with an adhesive tape 31 from the outside, and the adhesive tape 31 is cut almost from the center to collect the coating film 51.

  From the above, the coating film 51 can be easily collected without removing the opening 12 attached to the coating surface 50 during the coating film peeling operation. Since the opening / closing unit 15 is formed in the coating film collecting unit 22 that is opened to the bag-like body 11 and protrudes outward, the collected coating film 51 is collected in the coating film collecting unit 22, and the coating film collecting unit It can be easily recovered from the 22 opening / closing sections 15.
