Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard is proposed and managed by the National Certification and Accreditation Administration Committee.

This standard was drafted. People's Republic of China Anhui CIQ.

Introduction

Acrylic is usually a colorless liquid with a pungent odor; miscible with water, soluble in ethanol, ethyl ether. Acrylic acid derivatives of propylene Second only to polypropylene, acrylonitrile and propylene oxide derivatives of the fourth category, is an important organic synthetic raw materials and synthetic resin monomer, most for the manufacture of methyl acrylate, ethyl acrylate, butyl acrylate, hydroxy ethyl acrylate, etc., for the synthetic resins, synthetic fibers, superabsorbent, building materials, Paint and other industrial sectors. Acrylic main origin of Shanghai, Jiangsu, Zhejiang and other major importing countries as Japan, Korea and so on.

United Nations "on the Recommendations on the Transport of Dangerous Goods Model Regulations" (UNRTDG) acrylic main risk classified as Class 8 corrosive Substances, dangerous times classified as a Category 3 flammable liquid, UN No. 2218. Acrylic acid in the transport, storage, shall add certain the amount of polymerization inhibitor (eg. 4-methoxyphenol), suppressing self-polymerization of acrylic acid. Acrylic flammable vapor and air can form explosive mixtures, in case of fire, high-heat combustion caused the explosion. It can react with oxidants. In case of high fever, can occur polymerization reaction and emit a lot of heat Causing container rupture and explosion. On the skin, the eyes have a strong stimulating effect, slow wound healing. It can occur after contact with respiratory irritation symptom.

In March 2011 the State Council issued the "dangerous chemical safety regulations" [591 State Council Decree] provides for inspection and quarantine departments Responsible for the import and export of hazardous chemicals and their packaging implementation of the inspection. To ensure the effective implementation of the relevant inspection and quarantine operations, standardize import and export Dangerous chemicals and packaging inspection and supervision work, the development of this standard.

Import and export of dangerous chemicals inspection of acrylic acid Warning. Use of this standard should have the relevant inspection or testing work experience and relevant qualifications. This standard does not indicate all possible security issues. Users are responsible for the use of appropriate safety and health practices and to ensure compliance with relevant national regulations condition.

1 Scope
