Colorant detection method for ink detection

1, principle

The sample and the standard were diluted with a standard white ink, and the concentration of the diluted ink was compared and expressed as a percentage.

2, tools and materials

(1) Cone-shaped body of ink-powder knives, 200mm long, 20mm at the widest point, and 8mm at the narrowest point.

(2) Wiper blade made of stainless steel, 92mm × 59mm × 0.5mm, blade width of 9mm bending outward at 25 °.

(3) Scratch paper base paper (in line with ZB Y32 002), specifications 110mm × 65mm.

(4) Standard white ink.

(5) Standard black ink.

3, the instrument

(1) Analyze the balance with a maximum load of 200g and a volume of 1mg.

(2) Round glass sheet 2mm, diameter 90-100mm.

4, test conditions

(1) The test shall be conducted at a temperature of (25 ± 1) °C and a relative humidity of 65% ± 5%.

(2) Observe the divergent scraping, it should be under the D65 standard illumination body.

5, inspection steps

(1) Using an analytical balance, weigh 2 g of standard white ink and 0.2 g of sample ink on a round glass slide. In the same way, standard white ink and standard ink were weighed in the same ratio. The well-known ink is fully regulated with the ink-regulating blade.

(2) Apply about 0.5g of the standard sample with a spatula and apply it to the upper left of the scraping paper, and then take about 0.5g of the sample to be applied on the upper right of the scraping paper, and the two should not be connected.

(3) Place the doctor blade over the painted ink sample so that the body of the doctor blade is perpendicular to the scratch paper. Then, from the top down, the ink is scraped into a thin layer on the scratching paper, and when it is scraped to 35-45mm, the force is reduced, the angle inside the blade is approximately 25°, and the ink is painted on the paper to form a thick ink layer. . The final scraping shape should be similar to the schematic in GB/T 14624.1.

(4) Observe whether the face color and the ink color of the sample and the sample are the same. If they are not the same, change the amount of the standard white ink of the sample until the diluted sample is consistent with the standard sample. Calculate the percentage of the color strength of the sample according to the formula.

(5) After scratching, the ink color reflected in the observation within 30 seconds shall prevail.

6, test results

S=B/A×100%

In the formula, S—the percentage of coloring power (100% of the standard sample), %;

A - Dilute the standard amount of white ink, g;

B - dilute the amount of white ink sample, g.

Bronze Sculpture

Chinese people are very fond of sculpture, sculpture and other cultural arts. This art is relatively inherited. It has been in our country for a long time, and it has been up to now. Carving can not only carve out beautiful patterns, but also has the effect of cultivating one's character, which is a very good interest. In the sculpture industry, although the price of copper sculpture is relatively expensive, compared with sculptures made of other materials, the overall performance of copper sculpture is particularly excellent. It's very strong, safe and reliable. It is found that bronze sculptures are used very frequently in urban landscapes and are loved by citizens of all countries around the world. Bronze is hard and chemically stable. In history, bronze equipment has been used to make ritual instruments since the Shang and Zhou Dynasties, which are still well preserved. From the appearance, the appearance of the bronze sculpture is very natural and textured, the glaze looks very soft, and the rich copper layer reminds us of our long history and culture. Although copper is not as precious as gold or as shiny as aluminum alloy, its seemingly natural material can show a unique temperament, which is not possessed by other materials. I think the greatest commonality between sculpture and love is the pursuit of an eternal possibility. Sculpture gives its hard material, and love gives its clear soul."
