Description
Technical field
The utility model belongs to the chemical detection technique field, relates to a kind of detection bag of analyzing for formaldehyde, is specifically related to the detection bag of burst size of methanal in a kind of Fast Measurement wood-based plate.
Background technology
Wood-based plate is that to take timber or other non-wood plants be raw material, is processed into the different group element materials such as veneer, wood shavings or fiber, through applying adhesive and other adjuvants, reconfigures the sheet material of making.Because wood-based plate adopts Lauxite during fabrication mostly, it is tackifier, in tackifier, add formaldehyde can improve the performance of sheet material, and formaldehyde is volatile, and release period reaches 3-5, it is generally acknowledged allergen, be also one of potential strong mutagen, by the World Health Organization (WHO), be defined as carcinogenic and teratogenesis shape material, so the consumer more and more pay close attention to the burst size of methanal of wood-based plate.Country classifies wood-based plate as ten series products of emphasis regulation in recent years, starts to have strengthened the dynamics to the wood-based plate random checking, requires manufacturing enterprise should strictly control the burst size of methanal of artificial board.
Raising day by day along with the resident living level, have that large, structural good, the easy construction of breadth, rate of expand to shrink are low, dimensionally stable, material wood-based plate even than sawn timber, that be difficult for the advantages such as strain cracking be used widely in furniture, indoor decorating, in wood-based plate, the burst size of methanal index has become an important indicator of its application.At present, in wood-based plate, the mensuration of burst size of methanal in two steps: the first step is that the free formaldehyde that wood-based plate is discharged is collected, and it is dissolved in absorption liquid, and method has exsiccator method, WKI method (wide-necked bottle mensuration), perforation extraction, climate case method etc.; Second step is to adopt instrumental method quantitative test formaldehyde, uses spectrophotometric method, chromatography, electrochemical process etc. to measure the formaldehyde absorbent of collecting.All use instrumental analysis in the quantitative test of second step, these instrument detection sensitivities are high, quantitatively accurate, strong interference immunity, but testing cost is high, proving time is long, and need the professional to operate, and are difficult to popularize.Though spectrophotometric method equipment is simple, it is less to invest, sample pretreatment is loaded down with trivial details: (1) diacetone photometry (GB/T18580-2001) pre-treatment generates stable yellow substance needs 60min, and the reaction time is long, and needs to heat, and interference free performance is low; (2) chromotropic acid photometry, in test, the large and operation inconvenience of sulfuric acid consumption need be boiled heating in strong acid solution, and phenol, aldehydes have interference to mensuration, if be mixed with also interference measurement of nitrate ion in sulfuric acid.Therefore be necessary to develop a kind of simple, fast, the formaldehyde quantitative testing device that reliable, expense is lower, make check more rapidly, convenient.
The utility model content
The purpose of this utility model is that a kind of fast detecting bag of burst size of methanal is provided for the deficiencies in the prior art, but has the characteristics such as burst size of methanal in easy to operate, the low fast quantification wood-based plate of use cost.
The know-why that the utility model adopts: utilize formaldehyde to generate orange red compound with phloroglucinol reaction under alkali condition, the principle that shade is directly proportional to content of formaldehyde, design a kind of detector tube of measuring burst size of methanal in wood-based plate.
The technical scheme that the utility model adopts:
A kind of fast detecting bag of burst size of methanal, comprise wrapper, is provided with detector tube and colorimetric card in wrapper, and wrapper is hedged off from the outer world detector tube and colorimetric card, avoids detecting making moist of reagent, described detector tube comprises a transparent cylindricality tubular container, the top overcoat plug of cylindricality tubular container, can prevent that the external interference thing from entering in detector tube, impact detects effect, spaced two-layer sieve plate in the cylindricality tubular container, be enclosed to form an interlayer by two-layer sieve plate and cylindricality tubular container, between sieve plate, (being in interlayer) loads the colour developing potpourri consisted of developer and carrier, sieve plate plays a part fixedly filler, the colour developing potpourri is to be mixed by heating, drying and form with carrier by developer, the inside of cylindricality tubular container also is provided with piston, piston connects firmly with the pipe bolt, by the draw-tube bolt, can make piston move around in the cylindricality tubular container.The shades of colour section is set on described colorimetric card, and each color is corresponding to formalin and the reacted solution colour of developer of variable concentrations, and indicates the concentration of formaldehyde, and concentration unit is mg/L.Described developer is phloroglucin and NaOH potpourri; Described carrier is white zeyssatite.
When detecting, take off the plug of detector tube top overcoat, top is inserted and collected in the absorption liquid of burst size of methanal, the pipe bolt of pulling back, the pipe bolt drives piston and moves backward, make the space in the cylindricality tubular container form negative pressure, due to suction function, the collection liquid of formaldehyde is inhaled into the cylindricality tubular container, reacted 1min by sieve plate with the colour developing potpourri, observed the color of colour developing potpourri, with subsidiary colorimetric card contrast, learn the concentration range of formaldehyde in tested absorption liquid, thereby calculate the burst size of these wood-based plate samples formaldehyde in 24 hours.
The technique effect that the utility model reaches: 1, simple in structure, without reagent preparation, high efficiency; 2, without using any detecting instrument, easy and simple to handle, use cost is low, without the professional, detects, have simultaneously preserve convenient, the characteristics such as the term of validity is long; 3, contrast the color of testing result and colorimetric card by naked eyes, judged result, simple and clear; 4, without directly contacting chemicals, safe and reliable; 5, be applicable to the relevant law enforcement agency law enforcement such as hygiene department, quality supervision department, inspection and quarantine and epidemic prevention department and the heavy demand of woodwork manufacturing enterprise aspect production quality control.
The accompanying drawing explanation
