Abstract

The invention provides a paper penetration rate measuring device and method. The measuring device comprises a conductive plate; an insulating cylinder of which the bottom end is open, wherein the insulating cylinder is provided with a test port and a liquid injection port, and when the insulating cylinder is arranged on tested paper, the bottom end opening is closed by the tested paper; a power supply of which one pole is connected with one end of a first conductor, wherein the other end of the first conductor is connected with a conductive plate, the other pole of the power supply is connected with one end of a second conductor, and the other end of the second conductor penetrates through the test port and is suitable for being in contact with tested paper located in a space defined by the insulating cylinder and the tested paper or liquid injected on the tested paper; and a current sensor which detects the current in the first conductor or the second conductor. According to the paperpenetration rate measuring device and method, the method for indirectly reflecting the liquid penetration speed by measuring the liquid penetration amount is replaced, the paper liquid penetration rate is directly measured, and the paper liquid penetration speed is more accurately reflected; the measuring device automatically performs timing measurement and is convenient to operate and high in measuring result accuracy.

Description

technical field [0001] The invention belongs to the technical field of paper performance testing, and in particular relates to a paper permeation rate measuring device and method. Background technique [0002] The liquid permeation rate of paper is an important indicator of paper. Different uses of paper have different requirements for liquid permeation rate. For some uses of paper, it is expected that the slower the liquid permeation rate, the better. There are also some uses of paper, such as water transfer. For printing paper, it is expected that the faster the liquid (water) penetration rate, the better. Therefore, in many cases, it is necessary to measure the liquid penetration rate of a specific paper product. [0003] Water transfer printing technology is one of the commonly used methods for printing decorative patterns on the surface of porcelain, ironware and other products. The principle of water transfer printing technology is to print patterns, characters, etc. ...
