Abstract
The invention discloses an automatic online detection method for formaldehyde emission of an artificial board, which comprises the following steps: installing a formaldehyde detection mechanism on the conventional artificial board automatic sorting device, and screening and removing unqualified artificial boards according to whether the formaldehyde emission exceeds a preset value; the formaldehyde detection mechanism comprises a negative pressure fan and a formaldehyde sensor, the negative pressure fan collects volatile matters of each artificial board on line, after the volatile matters are detected by the formaldehyde sensor, if the formaldehyde emission amount exceeds a preset value, a signal is immediately transmitted to a controller on a conventional artificial board automatic sorting device, the artificial board automatic sorting device is assigned to sort out the artificial boards, and the formaldehyde emission amount of artificial board products is guaranteed to be qualified.
Description
Technical Field
The invention relates to the field of prevention and control of formaldehyde pollution of artificial boards, in particular to an automatic online detection method for formaldehyde emission of artificial boards.
Background
The formaldehyde is colorless gas, has pungent smell, and has stimulating effect on eyes and nose; the formaldehyde can be smelled at low concentration, and the olfaction threshold of human to formaldehyde is usually 0.06-0.07mg/m3(ii) a But has larger individual difference, and some people can reach 2.66mg/m3(ii) a Long-term and low-concentration formaldehyde contact can cause headache, dizziness, hypodynamia, sensory disturbance and immunity reduction, and can cause sleepiness, hypomnesis or neurasthenia and mental depression; chronic diseaseThe harm of poisoning to the respiratory system is huge, and long-term formaldehyde contact can cause respiratory dysfunction and hepatotoxic lesion, which are shown as hepatocyte damage, liver radiation energy abnormity and the like;
therefore, the zero-formaldehyde artificial board is a popular product in the board industry, and the binder containing formaldehyde is inevitably used in the production and manufacturing process, and although corresponding measures for removing formaldehyde are provided, whether zero-formaldehyde is completely realized cannot be guaranteed, so that the zero-formaldehyde factory inspection equipment for artificial boards is invented to ensure the product quality and avoid false propaganda, and needs to be solved by technical personnel in the field.
Disclosure of Invention
The invention aims to solve the problem that the formaldehyde emission of the artificial board is unqualified. Therefore, the invention provides an automatic online detection method for formaldehyde emission of an artificial board, which can screen out defective products containing formaldehyde and ensure that products with qualified formaldehyde emission can only leave a factory.
An automatic online detection method for formaldehyde emission of artificial boards is characterized in that a formaldehyde detection mechanism is installed on a conventional artificial board automatic sorting device, and unqualified artificial boards are screened and rejected according to whether the formaldehyde emission exceeds a preset value; the formaldehyde detection mechanism comprises a negative pressure fan and a formaldehyde sensor, the negative pressure fan collects volatile matters of each artificial board on line, after the volatile matters are detected by the formaldehyde sensor, if the formaldehyde emission amount exceeds a preset value, a signal is immediately transmitted to a controller on a conventional artificial board automatic sorting device, the artificial board automatic sorting device is assigned to sort out the artificial boards, and the controller is an STM32F103V8 single-chip microcomputer.
The invention has the advantages of high maturity, easy operation, low cost and the like, is operated automatically, saves labor cost, and has large market demand and wide application prospect.
