Abstract

The invention discloses a production device of fluorescent whitening agent VBL. The production device mainly comprises a condensation kettle (D101), a dissolution kettle (D102), a condensation kettle(D103), a condensation kettle (D104), an acid precipitation tank (D105), a kneading machine (L101), a baking room (L102), a sand mill (L103), a blender (F101), a filter (F102) and a suction filter barrel (F103), wherein the dissolution tank (D102) is respectively connected with the condensation kettle (D101) and the condensation kettle (D103), the acid precipitation tank (D105) is respectively connected with the filter (F102) and the suction filter barrel (F103), and the condensation tank (D101) has a nominal volume of 600-660L.

Description

technical field [0001] The invention relates to a compound synthesis device, in particular to a production device of fluorescent whitening agent VBL. Background technique [0002] Fluorescent whitening agent VBL can be mixed with anionic surfactants, anionic dyes (such as direct dyes, acid dyes, etc.) and pigments, but it is not suitable for use with cationic dyes, cationic surfactants, and synthetic resin initial shrinkage bodies. It is mainly used for whitening of cellulose fabrics and papers, brightening of light-colored fabrics and whitening of dyeing and printing. The dyeing performance of the whitening agent VBL is basically similar to that of the dye. It can be accelerated by salt, sodium sulfate, etc., and the leveling agent can be used as a retarder. The temperature and time are also closely related to the degree of dyeing. Most of the existing production devices are relatively complicated. The fluorescent whitening agent VBL is used as a cellulose whitening agent....
