And many base materials have the adsorption effect on formaldehyde, so a glass plate which does not adsorb formaldehyde is required to be selected as a cabin body base material, but the problem that samples are easy to remain on the base material due to smooth surface of the glass plate is easily caused, and particularly, the problem that the residues are easy to be pulverized or sprayed is solved, so that the problem of removing the residues is solved.
The test analysis of the formaldehyde concentration is carried out according to the spectrophotometry of the standard method for formaldehyde sanitation inspection in the atmosphere of the national standard GBT 16129-1995 residential district, and the test principle is as follows: formaldehyde and 4-amino-3-hydrazine-5-mercapto-1, 2, 4-triazene are condensed under alkaline condition, and then oxidized into 6-mercapto-5-triazene [4,3-b ] -S-tetraheliobenzene mauve compound by potassium periodate, and the reaction equation is shown as the following formula:
the spectrophotometric method has the advantages of strong anti-interference capability and serious interference to the acetylacetone method, the MBTH method and the parafuchsin methodThe method is free of interference. Therefore, the method is an effective method for measuring formaldehyde released in the resin crosslinking process, and has high sensitivity and the lowest detection limit of 0.01mg/m3It is suitable for detecting indoor air in general.

The handle is convenient to carry.
The watch glass is made of high borosilicate glass.
Preferably, the glass made of the high borosilicate has good chemical and physical properties, can resist water, acid and alkali, and most importantly, does not react with formaldehyde, does not interfere the formaldehyde purification process, and does not influence the purification capacity of the purification material; the glass has high hardness, can prevent the glass from being broken due to collision in the carrying process, and has stability and long service life; the surface dish increases the specific surface area of the liquid and the formaldehyde is evaporated quickly. Meanwhile, the high borosilicate glass has high transparency, so that the formaldehyde volatilization condition can be conveniently observed; the surface of the watch glass is smooth and easy to wash, and the influence of residual pollutant formaldehyde is prevented.
The testing method adopting the easy-to-clean rapid air purification detector comprises the following steps of:
coating or spraying a sample on the coating surface of the glass plate, dripping formaldehyde liquid on a surface dish after the sample is dried, and arranging a sealing cover of the cabin cover at an opening at the upper end of the cabin;
and (II) opening a fan to accelerate the air flow in the cabin body, closing the fan before sampling, sampling and extracting the gas in the cabin body by an air detection device every 0.8-1.2h, and detecting by adopting a formaldehyde concentration test analysis method, wherein the total sampling frequency is less than or equal to 3 times.
The test method has the advantages that the test cabin is convenient to clean, and the operation method and the detection are accurate.
The air detection device comprises an air sampler and a bubble absorption pipe connected between the air sampler and the air detection hole, wherein formaldehyde absorption liquid is filled in the bubble absorption pipe; the second step is that the air detection device samples and extracts the gas in the cabin body and the formaldehyde concentration test analysis method is adopted for detection, and the specific procedures are as follows: and starting an air sampler, sucking the gas in the cabin into the bubble absorption tube, allowing the gas to be absorbed by the formaldehyde absorption liquid, and then detecting the formaldehyde absorption liquid.
The formaldehyde concentration test analysis method comprises the following steps: taking 2mL of formaldehyde absorption liquid absorbing air in a test chamber, dropwise adding 1.0mL of 5moL/L potassium hydroxide solution, then adding 1.0mL of 0.5% AHMT solution to perform polycondensation reaction with formaldehyde for 20min, adding 0.3mL of 1.5% potassium periodate solution after the reaction is finished, oxidizing the polycondensation product into a mauve compound, fully shaking, and standing for 5 min; the absorbance of the purple-red compound was measured at a wavelength of 550nm, and the concentration of formaldehyde in the cabin was calculated from a standard curve prepared by Standard method for the sanitary inspection of formaldehyde in the atmosphere of GBT 16129-1995 residential area. The mode can quickly test the aldehyde removal rate of the material, has high test sensitivity, and can quickly measure the air purification capacity of the sample.
The sampling flow rate of the air sampler is 0.1-1L/min, the sampling time is 0.5-5min each time, and the dosage of formaldehyde absorption liquid is 1-3mL each time detection is carried out.
Preferably, the volume of single sampling is controlled to be 0.1-0.3L, and the volume of the cabin body is 0.008-0.012m3The volume of the air sampled at one time is 0.83-3.75% of the total air volume of the chamber body, which is close to the volume sampling ratio of 2.0% in GB/T16129-1995, so that the influence of the negative pressure generated by air sampling on the sampling process is reduced, and the requirement of national standard is met. When the sampling volume is 0.1-0.3L and the formaldehyde absorption liquid is 1.0mL, the sampled sample solution contains 0.198-3.198ug of formaldehyde pollutants; when the formaldehyde absorption solution is 3.0mL, the sampled sample solution contains 0.066-1.066ug of formaldehyde pollutants. The detection sensitivity is low due to too much absorption liquid and too low concentration of formaldehyde in the sample absorption solution, and if the consumption of the absorption liquid is too low, the formaldehyde concentration measurement cannot be characterized, so that the formaldehyde measurement range is not in the actual concentration range due to too much or too little absorption liquid, the test result is inaccurate, and 1-3ml is selected as the preferable amount.
And step (II) also comprises turning on the LED light source.
Turning on the LED light source can be used for testing of photocatalytic coatings.
