Foreword

GB/T 12008 "plastic polyether polyol" is divided into seven sections. --- Part 1. Designation system; --- Part 2. Specifications; --- Part 3. Determination of hydroxyl value; --- Part 4. Determination of sodium and potassium; --- Part 5. Determination of acid value; --- Part 6. Determination of the degree of unsaturation; --- Part 7. Determination of viscosity. This section GB/T 12008 Part 1, instead of the GB/T 12008.1-1989 "polyether polyol is named." The main difference compared to part with the GB/T 12008.1-1989 as follows. --- Increase the scope of content (in this part of the "1.2", "1.4" and "1.5"); --- Modified polyether polyols named configuration (the original standard "2.1", this section "2.1.2"); --- Modify the initiator functionality and a nominal molecular weight polyether polyols representation (the original standard "2.1.1", this part of the "2.2" and "2.3"); --- Modify the properties of modified or special code (the original standard "2.1.2", this section "2.4"); --- Modified to give additional information or other information (the original standard "2.1.3", this part of the "2.5"); --- Increased normative appendix "formula nominal molecular weight" (see Appendix A). This section of Appendix A normative appendix. This part is proposed by the China Petroleum and Chemical Industry Association. This part of the National Standardization Technical Committee of plastic products and plastic resins General Methods Chapter (SAC/TC15/SC4) centralized.

1 Scope

1.1 GB/T 12008 in the provisions of this part of the polyether polyol naming system. The system can be used as the basis for classification. 1.2 Different types of polyether polyols with the following nominal fixed specifies the names and characteristics of the project group initiator functionality, polyether polyols Molecular weight, modified or special performance distinction based on a naming system. a) The main initiator functional degree; b) Secondary functional initiator degrees; c) nominal molecular weight of the thousand; d) nominal molecular weight of hundreds digit; e) modified or special performance code. 1.3 part applies to the polyurethane material polyether polyol name. 1.4 part name does not mean the same polyether polyol must have the same performance. This section does not provide a description of polyether polyol Engineering Data alcohol special purpose and (or) method of processing required, performance data or data processing conditions. 1.5 To illustrate the use of some special polyether polyols, or production plant in order to distinguish or other information described in character group 4 are given additional requirements.

2 naming system

2.1 General 2.1.1 polyether polyol is named by name plus a fixed feature project team structure, stable names for polyether polyols, referred to as polyether. 2.1.2 polyether polyol naming system based on the following standard mode. name Fixed name Characteristics of the project team Group 1 Group 2 character character character character Group 3 Group 4 Characteristics of the project team made up of four groups of characters represents the performance characteristics of the composition. Character Group 1. represents a set of numbers initiator functionality. Position 1. The main initiator functionality degree (see 2.2) Position 2. Secondary functional starter degrees (see 2.2) Character Group 2. nominal molecular weight polyether polyol represents a set of numbers. Position 1. nominal molecular weight of the thousand (see 2.3) Position 2. hundreds digit nominal molecular weight (see 2.3) Character Group 3. represents the performance of modified or special code (see 2.4) Character Group 4. Additional information or other information can be given (see 2.5) in the character set of 4, if this information is given, it should burst 3 in cross Line "-" operator. 2.2 Character Group 1 In this group of characters, Arabic numerals functional degree of polyether polyol initiator. Multi-initiator of the polyether polyol bit 1 indicates the degree with a major functional initiator figures indicating the position 2 with secondary functional initiators degree numbers. Single initiator Polyether polyol, a position indicated by the degree of functional initiator figure 2 is not given location can be omitted. Functional initiator of common Table 1 degree. ......
