Problems solved by technology

In the prior art, the determination of volatile organic compounds (VOCs) in the ink of cigarette rods and box wrapping paper is done by sampling and testing the finished products after printing. This method not only cannot quantitatively measure the VOCs of raw material inks, Moreover, measuring after printing will increase the cost of printing enterprises.

Embodiment Construction

[0017] A method for quantitatively determining the VOCs of cigarette rods and cartridge inks described in the embodiments of the present invention comprises the following steps:

[0018] First, inject the ink that is evenly stirred and free of bubbles into the piston of the quantitative instrument and install the ink nozzle, and discharge the air at the nozzle end of the piston; secondly, squeeze the ink quantitatively onto the ink roller of the ink color development instrument through the scale on the quantitative instrument. Apply evenly on the left and right; again, start the ink color development instrument for ink distribution operation; the fourth step, after the ink distribution operation is completed, install the scraping paper, start the color development key to perform the color development operation; finally, after the color development operation is completed , measure the VOCs of printing ink by headspace-gas chromatography; The piston is a plastic piston; The ink n...

Abstract

The invention relates to a method for quantitatively measuring volatile organic compounds (VOCs) in ink for cartons and boxes of cigarettes. The method comprises the following steps: (1) injecting bubble-free ink which is uniformly stirred into a piston of a quantometer, mounting an ink nozzle, and discharging air at the ink nozzle end of the piston; (2) quantitatively extruding the ink onto an ink roller of an ink color developer according to scales on the quantometer, uniformly daubing from side to side; (3) starting the ink color developer for uniformly inking; (4) mounting scraping paper after the uniform inking operation is finished, starting a color developing key for performing color developing operation; and (5) measuring the VOCs of the ink through headspace-gas chromatography. The method has the beneficial effects that the VOCs in ink for cartons and boxes of cigarette is quantitatively measured before printing by the method, the method is simple and convenient, and an accurate measured value of VOCs in ink can be provided for cigarette pack printing, so that qualified finished products are well printed, and the cost is saved.

Description

technical field [0001] The invention relates to the field of cigarette pack printing, in particular to a method for quantitatively measuring VOCs of cigarette rod and box ink. Background technique [0002] National Tobacco Industry Standard YC / T207-2006 "Limits of Volatile Organic Compounds in Cigarette Rods and Packing Papers" and "Determination of Volatile Organic Compounds in Cigarette Rods and Packing Papers by Headspace-Gas Chromatography" were comprehensively promoted, It not only puts more pressure on cigarette pack printing companies, but also poses greater challenges to the determination of volatile organic compounds in inks, which are the main raw materials for cigarette strips and boxes. In the prior art, the determination of volatile organic compounds (VOCs) in the ink of cigarette rods and box wrapping paper is done by sampling and testing the finished products after printing. This method not only cannot quantitatively measure the VOCs of raw material inks, Mor...
