This standard specifies the requirements, sampling, test methods, inspection rules and marking, packaging, transportation and storage of DM (dibenzothiazole disulfide) vulcanization accelerator for rubber industry. This standard applies to DM vulcanization accelerator prepared from 2-mercaptobenzothiazole (vulcanization accelerator M) with air, sodium nitrite, sulfuric acid, hydrogen peroxide, chlorine, etc. GB/T 11408-2003 Vulcanization accelerator DM GB/T11408-2003 Standard download decompression password: www.bzxz.net

This standard replaces the GR/T 1°406-2C03. This standard is not equivalent to the international standard SK201 for rubber compounding agent testing method. This standard: 1. The difference between this standard and the international standard SK5-32GG7 is to facilitate the implementation of the standard. 5.2 of this standard is for the purpose of selection. Regarding the sieve residue, Australian standard 5K62c-2:2001 stipulates that the virtual method is used to determine the sieve residue of 0.(mm, 0.15:mm two-stroke grid sieve. This standard specifies the empirical method for measuring 3.1mm structure 115k22:12Ce: for the sixth standard). t||This standard GB/11.1G-8* flash + main differences are as follows: relevant ten war test methods are determined in accordance with the national standards, [S version of the 5th rate: the 5th rate of the version): the determination of the wetness of the test point, the details of the dynamic grid and the temperature rise flow 2 control band: 1 5, 1: this version, ): changed the heating practice of the humidity control (1989 edition 5.3: this version =.3:: change the wide range of temperature control of this specification (1989 edition before: 2: this version of 5.1, the technical back length of the qualified product and brand point (1989 edition of the 3rd share: the largest version of the 3rd high! : This standard is white! National Stone Pool and Chemical Industry Association proposed this standard National Rubber and Image Products Standardization Technical Committee Chemical Institute Division Technical Committee Will call. This standard starts from: Zhouzhou Chemical Industry Company, this standard is mainly produced by a single person.

The samples are divided into two groups and sealed with no less than 30 pieces. The plastic bottles are sealed with a ring label (packing): product name, number, purchase date, etc. The bottles are for inspection. In addition, the guarantee is implemented in each group. 5 Test method
The inspection results are given according to the provisions of C3/T[25\ standard production. 5.1 Appearance
R visual evaluation,
5.2 Determination of average melting point
The detailed format is as follows: 1.? mm~.1.m glass thickness is .2m~0.3m fill in the table to change the foreign 3mu~.6mm. heat source group% pre-excitation point is 25 hours. Cut off the minute 3 start swimming, the whole predicted refining point is 1, the capillary temperature safety meter center and the middle of the wet water ball are at the same - commercial degree. The wave transmission is 4 to 1 minute rise,
