Problems solved by technology

[0003] At that time, JJF1070-2000 "Rules for Inspection of Net Content of Quantitatively Packaged Commodities" once included the net content testing of pressurized quantitatively packaged commodities that significantly expand or gasify under normal pressure, similar to aerosols, in the rules, but Due to the lack of scientific and reasonable detection methods and means, which caused unnecessary controversy and misjudgment, this clause was removed when the rules were revised in 2005 and no longer included
Since the promulgation and implementation of the revised 1070, the inspection and testing institutions across the country have not formed scientific inspection methods and technical means to solve the problem of measurement inspection of such commodities. Not listed

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] A method for measuring and inspecting the quantity of household aerosol products, using the volume conversion method, first transferring the content of the aerosol to the density bottle, and using a vacuum pump and an air extraction valve to control the negative pressure of the density bottle during the transfer process: -90kPa ~ -95kPa , and use the injection valve to control the release of the content of the aerosol; then use the relative density method formula: Calculate the mass of the measured aerosol content.

[0026] Due to the internal pressure of aerosol products and the heterogeneity of the contents of the container, and the original shape cannot be maintained in the case of pressure loss, we cannot use conventional methods to detect its volume. In response to this problem, the main goal of this project is to transfer the content of...

Abstract

The invention relates to a household aerosol commodity quantity variable inspection method and a device. A volume conversion method is adopted so that firstly aerosol contents are transferred to a density bottle, and negative pressure of the density bottle is controlled by a vacuum pump and an extraction valve in the process of transferring, the negative pressure is -90KPa-95KPa, and the aerosol contents are controlled to release by an introduction valve. Then a relative density method formula is used to calculate quality of detected aerosol contents. The device comprises a port valve, a pipeline, the vacuum pump, the extraction pump, the introduction valve and the density bottle, the density bottle is connected with the extraction pump and the introduction valve by the port valve, the extraction valve is connected with the vacuum pump, and a material inlet of the introduction valve is connected with the port valve which is connected with a material outlet of a detected aerosol bottle. A sliding guide rail and a stepping motor are arranged below the detected aerosol bottle. A principle of differential pressure is adopted to solve the problem of transferring of the aerosol contents, solve the problem of control and transfer of the aerosol contents, and confirm the rules suitable for legal system measurement supervision.

Description

technical field [0001] The invention relates to an aerosol testing method and testing device. Background technique [0002] Although my country's aerosol industry started relatively late, it has developed rapidly. Aerosol products are mainly divided into six categories: personal products, household products, insecticide products, medical products and other products, including fire-fighting products. According to relevant data, my country currently produces nearly 1 billion cans of aerosol cans annually, ranking fourth in the world after the United States, Britain, and Germany, and has become a veritable world aerosol production and export country. Household products such as air fresheners, insecticide aerosols, and insecticide aerosol products (hereinafter referred to as "aerosols") have become indispensable daily commodities in people's daily lives. Whether the products with large quantity and wide range are accurate and sufficient is of special concern to the public. Howe...
