English name: Sodium salt of polynaphthalene sulphonic acid, 2-Naphthalenesulfonic acid, polymer with formaldehyde, sodium salt; FORMALDEHYDE-2-NAPHTHALENESULFONIC ACID-SODIUM SALT POLYMER); Naphthalenesulfonic acid/formaldehyde condensation product; 2-naphthalenesulfonic acid/formaldehyde sodium salt, Dispersant NNO
Composition: Sodium methylene bisnaphthalene sulfonate
Solubility: Dispersant NNO is easily soluble in any hardness of water, anionic;
Stability: acid resistance, alkali resistance, heat resistance, hard water resistance, inorganic salt resistance;
Appearance: beige brown powder;
Solubility: easily soluble in any hardness of water;
Performance: The dispersant NNO has excellent diffusibility and protective colloidal properties, but has no surface activity such as penetration and foaming, and has affinity for protein and polyamide fibers, and no affinity for fibers such as cotton and hemp.
Dispersant NNO is mainly used as dispersant in disperse dyes, vat dyes, reactive dyes, acid dyes and leather dyes. It has excellent grinding efficiency, solubilization and dispersibility; it can also be used in textile printing and dyeing, wettable pesticides as dispersant, and paper making Dispersants, electroplating additives, water-soluble paints, pigment dispersants, water treatment agents, carbon black dispersants, etc. The dispersant NNO is mainly used in industry for pad dyeing of vat dye suspensions, leuco acid dyeing, dispersing and soluble vat dyeing, etc. It can also be used for dyeing silk/wool interwoven fabrics, so that there is no coloring on the silk. Dispersant NNO is mainly used in the dye industry as a dispersion aid for dispersion and lake manufacturing, rubber emulsion stability, and leather tanning aid.
Conditions of Use
(1) The dispersant NNO is used as a dispersing and reducing agent for dispersing and reducing dyes. When the fineness of disperse or reducing dye particles is processed, the dispersant N and the dye can be added to the grinder and sand mill together with the dye. The amount of diffusing agent N is 0.5-3 times of vat dyes or 1.5-2 times of disperse dyes, some of which can be left as fillers when the dyes are commercialized;
(2) Dispersing agent NNO is used as vat dyeing: county floating body padding method: in padding bath, diffusing agent N3-5 g/l is generally added, and diffusing agent N15-20 g/l is generally added in reducing bath; Leuco acid method: Yixiu diffusing agent N dosage is 2-3g/l
(3) Dispersing agent NNO is used for dyeing with disperse dyes: When polyester is dyed at high temperature and high pressure, generally 0.5-1.5 g/L, diffusing agent N can be added to the dyeing bath; (4) Dispersing agent NNO is used for dyeing with ice dyes: To improve level dyeing and rubbing fastness, the amount of chromogen primer bath diffusing agent is generally 2-5 grams/liter, and the color bath diffusing agent N dosage is generally 0.5-2 grams/liter.
