Problems solved by technology

[0009] The present invention aims at the defect that it is difficult to accurately measure the height of the slurry in the reaction kettle in the prior art, and the large measurement error brings multiple repeated operations and long process time to the blending, so that the quality of the dyestuff decreases during the process , to provide a dye wet commercialization method, the method starts from the blended dye mixed slurry, and the actual additive amount is obtained through measurement and accurate calculation

Embodiment 1

[0034] A kind of active red wet method commercialization method, process flow chart sees figure 1 ,Specific steps are as follows:

[0035] 1. Mix two batches of dyes evenly in a 100 cubic meter reactor to obtain a semi-finished slurry. Take 100 g of the slurry sample and mark it as A 1 ;

[0036] 2. Add 200 kg Yuanming powder to the above-mentioned semi-finished product slurry, and stir for 1 hour to obtain a slurry dye sample, sample 100 g, and mark it as A 2 .

[0037] 1) From A 1 and A 2 Take 5g (accurate to 0.001g) from each of them and put them in an oven at 105°C to dry to constant weight, that is, measure the solid content (%)G 1 =25.6%, G 2 =26.2%;

[0038] 2) According to the solid content G 1 , G 2 Calculate the slurry amount M containing 1g solid dyestuff before and after adding Yuanmingfen 1 , M 2 , the amount of slurry containing 1g of solid dye (g) = 1 / solid content (%) (accurate to 0.001g), according to the calculation results to get M 1 =3.906, M 2...

Embodiment 2

[0071] A kind of wet blending of active navy blue, concrete steps are as follows:

[0072] 1. Mix two batches of dyes evenly in a 200 cubic meter reactor to obtain a semi-finished slurry. Take 100 g of the slurry sample and mark it as A 1 ;

[0073] 2. Add 700 kg of Yuanming powder to the above-mentioned semi-finished product slurry, and after stirring for 1 hour, obtain a slurry dye sample, take 100 g of the sample, and mark it as A 2 .

[0074] 1) From A 1 and A 2 Take 5g (accurate to 0.001g) from each of them and put them in an oven at 105°C to dry to constant weight, that is, measure the solid content (%)G 1 =29.5%, G 2 =31.0%;

[0075] 2) According to the solid content G 1 , G 2 Calculate the slurry amount M containing 1g solid dyestuff before and after adding Yuanmingfen 1 , M 2 , the amount of slurry containing 1g of solid dye (g) = 1 / solid content (%) (accurate to 0.001g), according to the calculation results to get M 1 =3.390, M 2 =3.226, take A with weigh...

Abstract

The invention relates to a method for wet commercialization of a dye. The method comprises the following steps of a, mixing dye raw materials into semi-finished slurry, b, sampling, c, detecting dyeing intensity C1 of the semi-finished slurry, d, accurately weighing W1 kg of an assistant, e, adding the assistant into the semi-finished slurry, f, stirring uniformly, g, detecting dye content C2 of the mixed slurry, h, comparing C1 and C2 respectively with standard dyeing intensity, i, calculating an original amount of a dye in the slurry according to a formula of W=W1C2 / (C1-C2), wherein in the formula, W represents the original amount (kg) of the dye in the slurry; W1 represents a use amount (kg) of the assistant; C1 represents the dyeing intensity (%) of the dye before assistant addition; and C2 represents the dyeing intensity (%) of the dye after assistant addition, j, calculating an actual use amount of the assistant according to the original amount of the dye in the slurry, k, adding the corresponding assistant into the slurry obtained by the step a, l, carrying out spray drying, and m, directly packaging into finished products. Through dye blending, measurement and accurate calculation of the method, an actual use amount of an assistant can be obtained.

Description

technical field [0001] The invention relates to a dye preparation method, in particular to a dye wet commercialization method. Background technique [0002] The dosage form and use performance of dyes are the most concerned things for dyeing factories. The commercialization of dyes is the final step in the dye manufacturing process. The wet commercialization of dyes is to add additives to the semi-finished dye stock, through repeated measurements and adjustments. To meet the quality requirements of standard products, compared with the current commercialization of dry method, not only is there no dust in the process, it is not flying and easy to dissolve in use, which is very popular in dyeing factories and has become the main trend. [0003] The wet commercialization of dyes is usually carried out in a large cylindrical reaction kettle with a slope of 50 to 200 cubic meters. It is necessary to prepare single or multiple batches of chemically synthesized dye slurry and auxi...
