Description
Technical field
The present invention relates to chemical industry measurement field, be specially a kind of preparation method of canister mouth neck ash discharge standardized level difference color board.
Background technology
The mouth neck ash discharge test of canister,, with pulse of air stream, ash is blown to canister, the dust collection of blowout has on filter board disk having certain area, result of the test canister ash discharge standardized level difference color board (hereinafter referred to as color board) carries out colorimetric to its disk, according to the colourity rank of filter board disk, judge that whether the ash discharge performance of canister is qualified.The air entering canister should be air pulse, namely simulates the breath state of people, requires that gas flow and respiratory rate and people are similar when moderate activity intensity.Collect the circular filter scraps of paper of testing sample, its quality must be identical with the filter paper making color board.
Why canister will carry out a mouthful neck ash discharge test, is because in canister except filter paper group is housed, be also filled with the impregnated carbon containing chromium.Wear and tear owing to being given a shock the chromium and dust that produce, and meeting enters the respiratory apparatus of the personnel of wearing along with air-flow, causes physiological damage to personnel.And chromium is one of carcinogen, harm more very.Therefore, from the angle of protecting mask wearer health, must be limited the ash discharge amount of canister.This performance indications are tested in mouth neck ash discharge test.
According in standard GB/T 2890-2007 about filter element ash discharge experimental test require in clear stipulaties, standardized level difference color board should be used.But as application specific standard material, color board only uses now in chemical defence industry, and ready-made product can not bought.
Canister mouth neck ash discharge standardized level difference color board, from founding the factory, uses the standardized level difference color board of the Soviet Union always.1964, chemical defence research institute have developed China's first generation breathing mask, and factory uses the differential color board of new standard of the supporting development of chemical defence institute instead still.1974, due to the foundation of the 11 breathing mask mobilization production lines in the whole nation, the demand of color board increased, and therefore, former our factory physics and chemistry room newly have developed a collection of standardized level difference color board and is issued to each mobilization production factory, uses till today always.Even to this day, then without unit developed new standardized level difference color board.
Now use color board when making, by the restriction of equipment and process, the precision of instrument equipment is lower, and manufacture craft also limits by condition, and color board precision is not high.And personnel at that time and instrument and equipment do not exist, concrete making details is had no way of textual criticism.Through By consulting literatures, there is no the relevant report of color board manufacturing technology yet.
After for many years, now change greatly with the whiteness value of color board, no longer applicable.Color board is the application specific standard material of protective equipment inspection, and it ensures canister mouth neck ash discharge test data Main Means accurately, should have strict production and administration system, to ensure its accuracy.
Summary of the invention
The object of the present invention is to provide a kind of method making canister mouth neck ash discharge standardized level difference color board, make the standardized level difference color board that precision is higher, meet the requirement of canister ash discharge performance test.
According to the regulation in requiring about filter element ash discharge experimental test in standard GB/T 2890-2007, standardized level difference color board divides two-stage, and Φ 30mm effectively filters in border circular areas, and additional powdered carbon quality is respectively the Ith grade of 0.12mg, the IIth grade of 0.24mg.

5) air pulse of resistance to broken ability: air mass flow 60L/min, respiratory rate 21 ~ 24 times/min under ash discharge experimental condition, 1min test period interior diameter 38mm filter paper disk does not break;
6) wettability: under suction filtration condition, filter paper can be spontaneously wet out by water, and wetting time is not more than 30s for the first time;
7) powdered carbon Equalsettlement: if wettability is better, under suction filtration condition, powdered carbon can uniform settlement to filter paper face;
8) whiteness: if above over-all properties meets the requirements, random test whiteness value 10 times, relative standard deviation≤0.5%.
The filter paper chosen is cut into the square plate of length of side 60mm, for making color board.The filter paper chosen is die-cut into the disk of Φ 38mm, tests for ash discharge.The quantity of filtering the scraps of paper can be decided in its sole discretion by consumption as required.
(4), production standard curve
4a, mounting filter, sandwich in filter by color board filter paper;
Wherein, design following filter, comprise glass bottle with frosted glass opening 101 and sand core funnel, as shown in Figure 2, described sand core funnel comprises infundibular body 102, and the neck root of described infundibular body 103 is connected with frosted mouth base 103, and the top of described frosted mouth base 103 is formed with vacuum orifice 105; The top of described infundibular body 102 is provided with core filter plate 104.As shown in Figure 4, described sand core funnel utilizes frosted mouth base 103 to be installed on glass bottle with frosted glass opening 101; On described infundibular body 102, docking is placed with water conservancy diversion container 106, with fixture 107 grips after placing color board filter paper 100 between the outlet of described water conservancy diversion container 106 and infundibular body 102.During use, install as shown in Figure 4, effective filtering surface of filter is Φ 40mm border circular areas, as shown in Figure 7.
Adopt above-mentioned filter to carry out the filtration of powdered carbon titer, its suction filtration face freely can be separated with upper container and by special clip clamping, can sandwich between suction filtration face and upper container by the filtration scraps of paper easily, convenient taking-up after suction filtration completes; This filter is core suction filtration face, not only can play good supporting role to filter, and draft is even, can make powdered carbon uniform settlement.
4b, the vacuum orifice of filter to be connected with vavuum pump, to open vavuum pump, with pure water by color board filter paper wetting 8-12 time repeatedly, shortening wetting time interval as far as possible.First time, time wetting, water was longer by filter paper spended time, about needs 10 ~ 15 seconds, after this all can pass through rapidly.
4c, filtration powdered carbon
The powdered carbon titer getting the 0.01mg/mL of certain volume is placed in the water conservancy diversion container on filter top, starts vavuum pump, by powdered carbon suction filtration on color board filter paper; For ensureing powdered carbon Equalsettlement, should be specifically noted that suction filtration speed, vacuum can not be too high.Generally, vacuum is-26 ~ 32kPa, makes powdered carbon titer pass through filter paper with the speed of 7 ~ 11mL/s.
