Introduction

The rational use of qualified dispersants is a necessary behavior to protect the marine environment. In order to unify and clarify the performance indicators and test methods of dispersants To determine the qualified dispersant products from the production, inspection and qualification of dispersants, and to further determine their use criteria and scope of application To achieve the rational use of qualified dispersant products.

GB/T 18188 "Oil Spill Dispersant" aims to unify the performance indicators and usage guidelines of dispersant products, and consists of two parts.

--- Part 1. Technical conditions. The purpose is to determine uniform performance indicators and test methods for the qualification determination of dispersant products. law, inspection rules.

--- Part 2. Guidelines for use. The purpose is to determine the use criteria and scope of application of dispersants, and to realize the rational use of dispersant products. to ensure that it plays an effective role in oil spill emergency response.

The implementation of GB/T 18188 unifies the test methods for dispersants in my country, defines performance indicators and usage guidelines, and is beneficial to the protection of water domain environment. GB/T 18188 was formulated in:2000 and has been released for more than 20 years. During this period, with the advancement of science and technology, product upgrading, The standard update corresponding to the relevant test methods, as well as the country's further emphasis on marine environmental protection, combined with the implementation of the:2000 version of the standard In order to further meet the requirements of marine environmental protection under the premise of maintaining its emulsifying performance and reduce secondary pollution, the performance indicators of dispersants require It is indeed necessary to revise and improve GB/T 18188.1 to continuously adapt to the new needs of the development of oil spill dispersants and ensure that they are used in the emergency response to oil spills. play its due role.

Through the revision, dispersant production enterprises can be promoted to improve technology transformation to meet the performance index requirements, so as to ensure that qualified dispersant products are in It plays an effective role in oil spill emergency practice, and under reasonable conditions of application, it can better promote the ecological environment, aquatic resources and coastal sensitive areas.
