Foreword
Revision of "Water-based Metal Cleaning Agent". During the revision, in addition to editorial modifications to the original standard and the correction of some typographical errors in JB432386
, its main technical content has also been changed: 1. The original 2.3 "Suitable for mechanical cleaning" has been changed to "Suitable for ordinary mechanical cleaning under normal pressure." 2. The original 3.2 "30 Machinery Oil" is changed to "N46HL Hydraulic Oil (oil used in ordinary machine tool industry). This standard will replace JB4323-86 from the date of implementation. This standard is proposed and centralized by Guangzhou Machine Tool Research Institute. This standard is responsible for Drafting units: Guangzhou Machine Tool Research Institute, Beijing Technical Exchange Station, Chaonan University. Main drafters of this standard: Li Maosheng, Tang Lianhua, Fan Shuqing, Liu Shilun 1Scope

This standard specifies the requirements for water-based metal cleaners Classification, technical requirements, packaging, marking, transportation and storage. This standard applies to water-based metal cleaning agents that are mainly composed of surfactants and various additives for cleaning oily metal materials and parts. 2 Reference standards ||tt ||The following standards contain provisions that, by reference in this standard, constitute provisions of this standard. The editions indicated are valid at the time of publication of this standard. All standards are subject to revision and parties using this standard should consider their use. Possibility of the latest version of the following standards. JB/T4323.2-1999 Water-based metal cleaning agent test method 3 classification
Water-based metal cleaning agents include filter, powder and paste products, which are divided into high-efficiency, Anti-rust type, low foam type and normal temperature type. 3.1 High-efficiency type
The product has excellent cleaning performance and does not corrode metal during the cleaning process. 3.2 Anti-rust type
The product does not corrode metal during the cleaning process. The residual liquid film has a temporary anti-rust effect on metal. It is divided into two categories according to its adaptability to metals:
Category 1: suitable for steel, cast iron and other ferrous metal alloys; Category 2: suitable for steel, aluminum, Copper and its alloys. 3.3 Low-foaming type
products have low-foaming properties and have temporary anti-rust effects on ferrous metals, and are suitable for normal mechanical cleaning under normal pressure. , divided into two categories according to their adaptability to oil stains: Category 1: suitable for cleaning light oil stains at room temperature: Category 2: suitable for cleaning heavy oil stains at room temperature. 4 Technical requirements
4.1 General requirements
4.1.1 The product should be harmless to the human body and have no strong irritating odor. 4.1.2 The product concentration should not exceed 5% (weight ratio). 4.1.3 The product shall be valid for no less than one year from the date of shipment under the specified conditions. . 4.2 The physical and chemical performance indicators and test methods are shown in Table 1.
