Dispersant MF is a common anionic surfactant. Its main component is methyl naphthalene sulfonate. It is often used in dyes, pigments, pesticides and other fields. Its main function is to improve dispersion performance and prevent particle aggregation and sedimentation. The following are the main features and applications of dispersant MF:   1. Main component Methyl Naphthalene Sulfonate Formaldehyde Condensate   2. Main features Good dispersibility: It can effectively disperse dyes, pigments and other solid particles that are insoluble in water.   Acid and alkali resistance: It is stable in a wide pH range and generally maintains good performance between pH 4-12.   Good thermal stability: It is suitable for high temperature environments, such as printing and dyeing and papermaking processes.   Strong compatibility: It can be used in combination with other additives and surfactants.   3. Main uses Dye industry: It is used as a dispersant for disperse dyes and vat dyes to improve the dispersion stability of dyes and prevent precipitation and agglomeration.   Pigment industry: It is used to disperse pigments such as carbon black and iron oxide to improve the stability of color paste. Pesticide industry: used as a dispersant for wettable powder (WP), water dispersible granules (WDG) and other preparations to improve drug efficacy. Ceramic industry: used for dispersing ceramic glazes and mud to prevent sedimentation and improve uniformity. Papermaking industry: can be used as a pulp additive to enhance paper dyeing effect. Concrete industry: used in cement and concrete systems to improve fluidity and reduce water-cement ratio. 4. Physical and chemical properties Appearance: brown powder or brown liquid Solubility: easily soluble in water pH value (1% aqueous solution): about 7-9 Active ingredient: usually ≥90% (powder) or 40-50% (liquid) Ionicity: anion 5. Difference from dispersant NNO Dispersant MF uses methylnaphthalene as the main raw material, has strong dispersing ability, better high temperature resistance and acid and alkali resistance, and is often used for high temperature dyeing. Dispersant NNO uses naphthalene as the main raw material, has slightly weaker dispersing performance, but is widely used in textile printing and dyeing, concrete, and has a low cost.
