AI Summary AI generated
This standard specifies a method for determining the diffusibility of disperse and vat dyes. The principle involves dropping a dye suspension onto filter paper to form a diffusion ring, which is then compared with a standard rating card to assign a diffusibility grade (1 to 5). It details the preparation of the dye suspension, the preparation of the filter paper diffusion ring, and the rating procedure, referencing standards for filter paper, dyeing conditions, and water quality. It is applicable for quality control in dye production and use.
本标准规定了分散染料和还原染料扩散性能的测定方法。原理是将染料悬浮液滴在滤纸上形成渗圈，通过与标准评级卡对比来评定扩散性能等级（1-5级）。详细描述了染料悬浮液的制备、滤纸渗圈的制备和评级步骤，并引用了相关滤纸、染色条件和水质标准。适用于染料生产和使用中的质量控制。

染料悬浮液在滤纸上形成渗圈时，根据渗圈中心的染料沉积情况可以定性地确定染料扩散性能的优劣。
通过与“染料扩散性能评级卡”中的滤纸渗圈对比评级来评价染料扩散性能。
准确称取染料样品0.5 g(精确至0.001 g)，置于150 mL烧杯中，加入少量30℃的蒸馏水，将染料调成浆状，再加入蒸馏水，使总体积为100 mL。
将滤纸水平放置在表面皿上，在搅拌的情况下，用刻度吸管从按本标准的6.1制备的染料悬浮液的中部吸取0.2 mL染料悬浮液。
1级：表示扩散性能很差；2级：表示扩散性能差；3级：表示扩散性能一般；4级：表示扩散性能较好；5级：表示扩散性能很好。
When the dye suspension forms a diffusion ring on the filter paper, the deposition of dye at the center of the ring can qualitatively determine the diffusibility of the dye.
The diffusibility is evaluated by comparing the filter paper diffusion ring with the filter paper diffusion rings in the 'Rating Card for Diffusibility of Dyestuffs'.
Accurately weigh 0.5 g (accurate to 0.001 g) of the dye sample, place it in a 150 mL beaker, add a small amount of distilled water at 30℃, stir the dye into a paste, then add distilled water to make the total volume 100 mL.
Place the filter paper horizontally on a watch glass, and while stirring, use a graduated pipette to draw 0.2 mL of the dye suspension from the middle of the suspension prepared according to 6.1 of this standard.
Grade 1: indicates very poor diffusibility; Grade 2: indicates poor diffusibility; Grade 3: indicates average diffusibility; Grade 4: indicates good diffusibility; Grade 5: indicates very good diffusibility.
