GB/T 17514-2017Water treatment chemicals - Anionic and non-ionic polyacrylamides (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 17514-2008 "water treatment agent polyacrylamide." This standard compared with GB/T 17514-2008, the main The technical changes are as follows:

--- The standard name was changed from "water treatment agent polyacrylamide" to "water treatment agent anionic and non-ionic polyacrylamide";

--- Deletion of the determination of the degree of hydrolysis (see.2008 version 5.2);

--- Increased determination of anionic degree (see 5.4).

--- Determination of acrylamide monomer content by gas chromatography modified to liquid chromatography (see 5.5,.2008 edition 5.4.1);

--- Remove the determination of acrylamide monomer content bromination method (see.2008 edition 5.4.2);

--- Increased chloride and sulfate content indicators and determination methods (see Table 1 and 5.9,5.10). This standard proposed by the China Petroleum and Chemical Industry Federation. This standard by the National Standardization Technical Committee water treatment chemicals Technical Committee (SAC/TC63/SC5) centralized.

1 Scope

GB/T 17514-2017 is the Chinese national standard on water treatment chemicals - anionic and non-ionic polyacrylamides, in the field of chemical technology. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 7 September 2017 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 April 2018. Classification: ICS 71.100.80, CCS G77. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the water treatment agent anionic and non-ionic polyacrylamide product requirements, test methods, inspection rules and signs, Packaging, transportation, storage and so on. This standard applies to anionic and non-ionic polyacrylamide products, the product is mainly used for drinking water, industrial water and wastewater, sewage Treated flocculants and sludge dehydrating agent.
