Abstract

The invention discloses a detection method for chemical permeation resistance of protective clothing. The method comprises the following steps: extracting a sample piece from a specific position of the protective clothing; loading the sample piece into a permeation unit and performing a permeation simulation process; acquiring a specific quantity of samples on the sample piece every given time; detecting content of a target object in the samples and calculating a permeation rate result. Compared with the conventional detection technology, the detection method for chemical permeation resistance of the protective clothing mainly has the advantages that permeation tests are performed on the protective clothing in the permeation unit, so that the quantitative feature of the chemicals during testing is improved, and testing is more accurate; by means of an added sampling step, the testing cost is reduced, and online monitoring difficulty is reduced.

Description

technical field [0001] The invention relates to the field of detection, in particular to a detection method for chemical penetration resistance of safety clothing. Background technique [0002] Safety protective clothing is a solid guarantee for the health of operators in the chemical industry. It can effectively block the damage of chemicals. Its quality is especially the key performance-resistance to chemical penetration is very important. my country, some international organizations, and other countries have formulated strict laws and regulations to limit the chemical permeability rating of safety protective clothing, requiring that each component of safety protective clothing must be able to block the penetration of harmful chemicals within a certain period of time. At present, the main testing methods for protective clothing include ASTM_F903-03, ASTM F 739-1999, GBT 23462-2009, etc. [0003] The current detection methods are mainly divided into two categories, one is ...
