Description
Technical field
The utility model relates to a kind of producing device of filter paper, is specifically related to a kind of for measuring the producing device of the color spot filter paper that raindrop diameter uses.
Background technology
Color spot refers to coats colorant on filter paper, when raindrop drop on filter paper, leaves the color spot of permanent sub-circular.It is the principle based on " the color spot size that raindrop form on same material is relevant to the diameter of raindrop " that color spot method is measured raindrop diameter, pre-determined the relation between raindrop diameter and color spot diameter, the color spot size then forming on same material by measurement raindrop is known corresponding raindrop diameter by inference.Between raindrop diameter and color spot diameter, there is power function relationship as shown in Equation 1:
D=kD
n(formula 1)
In formula 1: d-raindrop diameter; K-coefficient; D-filter paper color spot diameter; N-index.
Wherein, on the kind of the coefficient k of color spot filter paper and the size of index n and the kind of filter paper, colorant and filter paper, the consumption of colorant is directly related.
Yet, on present market, not having special color spot filter paper and sell, user cannot be bought directly and be obtained by market, needs self manufacture color spot filter paper, and the coefficient k of definite filter paper and index n.The method for making of common color spot filter paper is: with hairbrush, colorant powder is evenly coated on filter paper, flicks filter paper and can make color spot filter paper to flick off unnecessary colorant powder.
At present, the coefficient k of color spot filter paper and index n mostly adopt with the following method and determine: adopt the syringe needle (or different bore test tube) of common injector for medical purpose and different model to serve as raindrop generator, by measuring the gross mass of a plurality of raindrop, then by the quality of the single raindrop of mean value calculation, by the relational expression of raindrop quality and raindrop volume, try to achieve raindrop diameter, as shown in Equation 2:
In formula 2: d-raindrop diameter; M-raindrop quality; π-circular constant; ρ-water-mass density.
The different raindrop of diameter, drop in respectively the color spot that forms different sizes on color spot filter paper, by measuring the area of color spot, calculate corresponding color spot diameter, then by a plurality of different raindrop diameters and corresponding color spot diameter, carry out regretional analysis, draw raindrop diameter and color spot diameter Relationship figure, obtain coefficient k value and Index n Value in raindrop diameter d and color spot diameter D power function relationship formula.
Color spot filter paper is measured accuracy and the reliability (repeatability) of raindrop diameter, can be subject to making the impact of color spot filter paper and Coefficient of determination k and index n.Use definite method of above-mentioned color spot filter paper method for making and coefficient k, index n, accuracy and reliability (repeatability) are not high.Different experimenters, is using identical qualitative Medium speed filter paper at present, and in the situation of identical coating, the coefficient k value obtaining is between 0.30～0.46, and Index n Value is between 0.66～0.78.The larger difference of visible different experimenter's experiment value, traces it to its cause, and the method for making of current color spot filter paper at least exists following problem:
(1) manual with hairbrush brushing colorant powder on filter paper, can not effectively colorant powder be coated on filter paper equably, cause colorant powder skewness on filter paper, cause the raindrop of same diameter on color spot filter paper, to produce the color spot of different sizes.Meanwhile, operate by hand hairbrush brushing colorant powder, colorant powder can be dispersed into surrounding environment and pollute, unfavorable to health;
(2) colorant powder skewness on filter paper, and produce the diameter of raindrop and departing from more greatly of actual raindrop diameter, cause determining that coefficient k value and the Index n Value of filter paper are inaccurate.
