Technical field
The utility model relates to a kind of methylene oxide detecting instrument device, is particularly useful for the burst size of methanal device for fast detecting of wooden furniture, woodwork, timber floor etc.
Background technology
At present to indoor formaldehyde pollution level (concentration value, mg/m 3) detection, instrument commonly used expensive returns the laboratory to spot sampling and carries out the splitting ratio colour test.These a little instruments are minimum ten thousand yuan of the 5-8 that also need at present, your person reach hundreds of thousands or more than, and detect in fact mainly is at various decorating and renovating materials, especially wooden furniture, woodwork carry out, therefore as long as detect the requirement of the burst size of methanal conformance with standard regulation of wooden furniture, woodwork, timber floor in the laboratory, these products are used for that its burst size of methanal is exactly safe when indoor.
In the face of expensive instrument and numerous and diverse burst size of methanal detection, purchasing such equipment for general mechanism obviously is a no small input, it is also considerable to carry out its expense of one-time detection for the consumer, often be difficult to realize, thus formaldehyde to pollute be pain of the consumer mind that is difficult to eliminate always.
The utility model content
The purpose of this utility model provides that a kind of detection speed is fast, operating cost is low, precision is high, strong interference immunity, mainly is applicable to the burst size of methanal device for fast detecting of decorating and renovating materials such as wooden furniture, woodwork, timber floor.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of burst size of methanal device for fast detecting, comprise the sample cabin that is used to place sample, in this sample cabin, heating arrangements is installed and is provided with air duct, be respectively equipped with air in and mixed gas outlet on this sample cabin, its special feature is, the air in described sample cabin is by pipeline and pneumatic pump, spinner-type flowmeter, exsiccator, wash bottle and air strainer UNICOM successively, and the gas vent in described sample cabin is by pipeline and at least one road valve and absorption bottle UNICOM successively.
Wherein the mixed gas outlet in sample cabin by pipeline respectively with four way valve door and absorption bottle UNICOM successively.
Wherein thereby the mixed gas outlet in sample cabin is also used by pipeline and the independent UNICOM of one road valve cleaning sample cabin.
Wherein sample cabin inside and outside wall is provided with interlayer, and heating arrangements is made up of heat tape and supporting temperature controller, and heat tape is installed in the interlayer, and an end of this interlayer engages with air in, its other end and sample cabin interior bonds.
The temperature sensor of detectable sample cabin internal temperature wherein also is installed on the sample cabin.
The flow sensor that is connected with air in wherein also is installed on the sample cabin.
The utility model provide a kind of practical, easy to operate, cost performance is high, detection speed is fast, precision is high, the burst size of methanal device for fast detecting of strong interference immunity, mainly is applicable to the mensuration of decorating and renovating material burst size of methanal such as various wooden furnitures, woodwork, timber floor.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Principle of work of the present utility model is the sample of known surface area to be put into the sample cabin 15 of the formaldehyde release-absorption apparatus of uniform temperature, humidity, air mass flow and pressure, the airflow for the treatment of the formaldehyde that discharges in the sample and entering in the sample cabin 15 mixes, the formaldehyde in the mixed gas constantly by with absorption bottle 21 that sample cabin 15 is connected in absorption liquid (distilled water) absorption.With the concentration of formaldehyde in the spectrophotometric determination absorption liquid, calculate the burst size of methanal of sample, test result mg/m by the surface area of this concentration of formaldehyde, formaldehyde soak time and sample 2.h expression.
The utility model need be removed the wide edge strip of every limit 200mm to wooden sample when test, cut into onesize sample, be of a size of 400mm * 50mm * thickness of slab, all test samples must be placed in the container (or sealing bag) of sealing, behind the specimen preparation, store at room temperature immediately.The necessary edge sealing of tested sample can adopt the wax of brushing fusing or use the aluminium foil Pressure sensitive adhesive tape.
Come the utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model comprises the sample cabin 15 that is used to place sample, in this sample cabin 15, heating arrangements is installed and is provided with air duct, these 15 two ends, sample cabin are respectively equipped with air in and mixed gas outlet, the air in sample cabin 15 is by pipeline and pneumatic pump 4, spinner-type flowmeter 6, exsiccator 3 (specifically can adopt the silica dehydrator bottle), wash bottle 2 (interior dress distilled water) and air strainer 1 UNICOM successively, thereby this part mainly is pure and dryly avoid influencing testing result in order to keep entering air in the sample cabin 15.
The mixed gas outlet in sample cabin 15 is by pipeline and at least one road valve 10 and absorption bottle 21 UNICOM successively, specifically can be sample cabin 15 mixed gas outlet by pipeline respectively with four way valve door 10 and absorption bottle 21 UNICOM successively.
