Description

Technical Field

[0001] The present application relates to the field of coating detection technology, and in particular to an instrument for quickly identifying the zinc content in cold-applied zinc coatings at a construction site. Background Art

[0002] Zinc, as a common metal element, plays an important role in coatings. It can improve the anti-corrosion performance of coatings and increase the durability and service life of coatings. Therefore, the zinc content in coatings has become an important indicator for evaluating coating performance. Common methods for detecting zinc content in coatings include atomic absorption spectroscopy, inductively coupled plasma emission spectroscopy, etc. These methods are based on the spectral characteristics of atoms or ions and can accurately measure the zinc content in coatings. Before conducting zinc content testing, it is usually necessary to properly treat the coating sample, such as dissolving, diluting, etc., to facilitate subsequent measurements. The current shortcomings of identifying zinc content in coatings mainly include the following aspects:

[0003] 1. Destructive testing: Some traditional methods for testing zinc content in coatings may require destroying the coating sample, which means that non-destructive testing is not possible. This destructive testing may not be practical for large-scale production and quality control;

[0004] 2. High time cost: Some detection methods may take a long time to complete analysis and measurement, which may lead to production delays and reduced efficiency;

[0005] 3. Technical complexity: Some advanced detection methods, such as spectral analysis, may require specialized technical knowledge and equipment. This increases the cost and complexity of the test and may require specialized operators;

[0006] 4. Affected by interference factors: Some detection methods may be affected by other elements, resulting in inaccurate results. This requires additional measures to eliminate interference factors, which increases the complexity and cost of detection. Utility Model Content

The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0038] The embodiment of the present application provides an instrument for quickly identifying the zinc content in cold-applied zinc coatings at a construction site, such as Figure 1-Figure 2As shown, the instrument includes a base 100, a bracket 200, a metering container 300, a scraper 400, and a weighing device 600. The bracket 200 is fixed to the base 100. The metering container 300 has a capacity of one liter. The top of the metering container 300 is open to form a feeding port 301. The edges of the feeding port 301 are located in the same horizontal plane. The bottom of the metering container 300 is provided with a discharge port 302, and the discharge port 302 is provided with a removable sealing member 500. The scraper 400 is used to scrape off the cold-coated zinc coating material that overflows the feeding port 301, so that the metering container 300 can quantitatively measure one liter of cold-coated zinc coating material. The weighing device 600 is located below the metering container 300 and includes an electronic scale 610 and a receiving container 620 disposed on the electronic scale 610. The receiving container 620 is used to receive the cold-coated zinc coating material flowing out of the discharge port 302.

[0039] The receiving container 620 can be a beaker, and the volume of the beaker only needs to be greater than one liter.

[0040] When the instrument is actually used, the entire instrument is placed at room temperature, the reading of the electronic scale 610 is reset to zero, the cold zinc coating paint is poured into the quantitative container 300, and the portion overflowing the feeding port 301 is scraped off with the scraper 400 so that the cold zinc coating paint and the feeding port 301 at the top of the quantitative container 300 are kept at the same horizontal line. In this way, a volume of 1 L of cold zinc coating paint can be quickly and accurately measured. Then, the blocking member 500 on the discharge port 302 is removed, and the cold-coated zinc coating material in the quantitative container 300 flows into the receiving container 620 of the weighing device 600 below. At this time, the electronic scale 610 will have a reading. According to the mass formula m=ρv and the description of the density of solvent-based cold-coated zinc and water-based cold-coated zinc in "GB / T 6750", the density of solvent-based cold-coated zinc is ≥2.7g / ml, and the density of water-based cold-coated zinc is ≥2.9g / ml. If the measured solvent-based cold-coated zinc coating meets the zinc content standard, the electronic scale 610 reading is ≥2.7kg; if the measured water-based cold-coated zinc coating meets the zinc content standard, the electronic scale 610 reading is ≥2.9kg. Otherwise, the zinc content in the cold-coated zinc coating is unqualified.

[0041] In the embodiment of the present application, the instrument comprises a base 100, a bracket 200, a one-liter quantitative container 300, a scraper 400, and a weighing device 600. The instrument has a simple structure and can be used to quickly determine whether the zinc content of a cold-applied zinc coating is ≥95%. This is time-saving and easy to operate. Because the test is entirely physical, it does not damage the cold-applied zinc coating composition, and the cold-applied zinc coating can continue to be used after testing.

[0042] In one embodiment, if Figure 2-Figure 3As shown, the quantitative container 300 includes a cylindrical portion 310 and a conical portion 320, the large end of the conical portion 320 is connected to one end of the cylindrical portion 310, the small end of the conical portion 320 forms a discharge port 302, and the end of the cylindrical portion 310 away from the conical portion 320 forms a feeding port 301.

[0043] The quantitative container 300 is designed to be funnel-shaped from the top, and its internal structure is conducive to the flow of cold-coated zinc paint. The inner wall of the conical cylinder 320 can be further designed to have a large inclination angle, and the small end of the conical cylinder 320 can be designed to have a wider outlet, so that the cold-coated zinc paint can flow out more smoothly and avoid residue inside the quantitative container 300.

[0044] In actual use, the quantitative container 300 can be rinsed with a small amount of the same solvent or cleaning agent as the paint to be measured to moisten the surface of the quantitative container 300 and reduce the adhesion of the cold-coated zinc paint. The purpose is to avoid the residue of cold-coated zinc paint in the quantitative container 300 and improve the measuring accuracy of 1L of cold-coated zinc paint.

[0045] In a specific embodiment, the inner wall of the quantitative container 300 is smooth and does not chemically react with the cold-coated zinc coating. Understandably, the purpose of the smooth inner wall is to reduce the adhesion of the cold-coated zinc coating, prevent the cold-coated zinc coating from remaining in the quantitative container 300, and improve the measurement accuracy of 1L of cold-coated zinc coating. The inner wall of the quantitative container 300 does not chemically react with the cold-coated zinc coating, which does not cause the cold-coated zinc coating used for testing to denature, allowing it to continue to be used after testing, thus saving costs.

[0046] In a further specific embodiment, Figure 3 As shown, the inner wall of the quantitative container 300 is provided with an anti-stick coating 3001 , such as a Teflon coating, so as to prevent the cold-coated zinc paint from adhering to the inner wall of the quantitative container 300 .

[0047] In one embodiment, if Figure 1-Figure 2 As shown, the bracket 200 includes a column 210, a cross bar 220 and a supporting ring 230. The column 210 is vertically fixed on the base 100, one end of the cross bar 220 is connected to the upper end of the column 210, and the other end is connected to the supporting ring 230. The supporting ring 230 is arranged horizontally, and the inner diameter of the supporting ring 230 is larger than the small end of the conical cylinder 320 and smaller than the large end of the conical cylinder 320. The quantitative container 300 is placed on the supporting ring 230 from top to bottom, and the supporting ring 230 is used to support the quantitative container 300. The structure is simple.

[0048] In one embodiment, if Figure 1-Figure 3 As shown, the blocking member 500 includes a magnetic blocking plate, and a magnetic attraction member 700 is embedded at the discharge port 302 . The blocking plate can be magnetically attracted and block the discharge port 302 , and the blocking plate can be horizontally removed from the discharge port 302 to open the discharge port 302 .

[0049] It is understandable that if a valve is set on the discharge port 302, due to the complex internal structure of the valve, the cold-coated zinc paint is likely to remain inside the valve, affecting the measurement accuracy of 1L of cold-coated zinc paint; if a rubber plug is used to seal the discharge port 302, at the moment the rubber plug is removed, the cold-coated zinc paint flowing out of the discharge port 302 is likely to drip onto the hands of the inspector, which also affects the measurement accuracy of the cold-coated zinc paint and the accuracy of the weighing results.

[0050] In the embodiment of the present application, a sealing plate is used to seal the discharge port 302 , which has a simple structure. When the discharge port 302 needs to be opened, one end of the sealing plate is pinched and pulled horizontally to overcome the magnetic attraction of the magnetic element 700 at the discharge port 302 .

[0051] Specifically, the magnetic attraction member 700 can be a plurality of magnet blocks arranged around the discharge port 302, and the sealing plate can be a magnetic plate.

[0052] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
