The alkali-resistant penetrant AEP (fatty alcohol polyoxyethylene ether phosphate, CAS: 68439-39-4) is an anionic surfactant. It has stable chemical structure and undiminished penetrating power in high-concentration alkali baths, while also possessing acid resistance, hard water resistance, and high-temperature stability. It is a multifunctional and efficient auxiliary agent.
The following application fields and processes are sourced from authoritative technical materials in the Guoli Chemical product database.
| Industry | Specific Process | Role Description |
|---|---|---|
| Textile Dyeing and Finishing | Alkali-oxygen One-bath Scouring and Bleaching | Helps alkali liquor and hydrogen peroxide penetrate quickly and evenly, improving scouring and bleaching efficiency and whiteness uniformity |
| Cold Pad-batch Pretreatment | Maintains excellent penetrating power during low-temperature long-time stacking, ensuring the treatment liquid fully wets the fabric | |
| Desizing | Accelerates the penetration and swelling of caustic soda into the sizing material, promoting rapid removal of the size | |
| Mercerizing Penetration | Promotes rapid and uniform penetration of concentrated alkali into cotton fibers, enhancing the mercerizing effect | |
| Leather Industry | Soaking | Accelerates the penetration of water and auxiliaries into the dry hide, shortening the rehydration time of raw hides |
| Degreasing | Enhances the penetration and emulsification of natural fats in the hide under alkaline conditions, achieving deep degreasing | |
| Papermaking Industry | Waste Paper Deinking | Promotes the penetration of deinking agent into the interface between ink and fiber, effectively stripping ink and preventing redeposition |
| Alkaline Cooking Penetration | Accelerates the penetration of cooking liquor into wood chips or grass raw materials, improving cooking efficiency and pulp yield | |
| Metal Surface Treatment | Alkaline Degreasing Cleaning | As a penetrating component of metal cleaners, enhances the penetration and emulsifying ability of alkaline cleaning solution for oil stains |
| Industrial Hard Surface Cleaning | Hard Surface Alkaline Cleaning | Improves penetrating power, helping to quickly break down and remove stubborn oil and dirt |
This product can achieve "one agent, multiple uses," effectively shortening processes, reducing the variety of chemicals, and lowering overall operating costs. It has strong formulation compatibility and can be used in the same bath with various auxiliaries and high-concentration electrolytes. It is recommended to perform compatibility tests before use to optimize the process recipe.
