Alkali-resistant penetrant AEP (fatty alcohol polyoxyethylene ether phosphate) is an anionic surfactant whose core advantage lies in maintaining excellent penetrating power and chemical stability even in high-concentration alkali baths, a trait that ordinary penetrants struggle to match. Therefore, it has become the preferred auxiliary agent in strong alkali processes such as alkali-peroxide one-bath scouring and bleaching, cold pad-batch pretreatment, and mercerizing penetration. Additionally, this product offers resistance to acids, hard water, and high-temperature stability, enabling it to continuously perform under various complex operating conditions.
In the field of textile printing and dyeing, AEP rapidly reduces the surface tension of the working fluid, promoting uniform diffusion of alkali liquor and auxiliaries into the fiber interior, thereby improving the uniformity and efficiency of pretreatment. In papermaking and leather processing, it helps chemical solutions penetrate deep into fibers or leather hides, accelerating reaction processes and improving product quality. In metal cleaning and industrial hard surface cleaning, AEP enhances the penetration and stripping ability of alkaline cleaning solutions against stubborn oil stains.
| Application Industry | Specific Process | Function Description |
|---|---|---|
| Textile Printing and Dyeing | Alkali-peroxide 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 long-term low-temperature stacking, ensuring full wetting of the fabric by the treatment solution | |
| Desizing | Accelerates the penetration and swelling of caustic soda into the sizing agent, promoting rapid stripping of the size | |
| Mercerizing penetration | Promotes rapid and uniform penetration of concentrated alkali liquor into cotton fibers, enhancing the mercerizing effect and fabric luster | |
| Leather Industry | Soaking | Accelerates the penetration of water and auxiliaries into the interior of dry hides, shortening the soaking time for raw hides |
| Degreasing | Enhances the penetration and emulsifying ability of natural oils within the hide under alkaline conditions, achieving deep degreasing | |
| Papermaking Industry | Deinking of waste paper | Promotes penetration of deinking agents into the interface between ink and fiber, effectively stripping ink and preventing redeposition |
| Alkaline cooking penetration | Accelerates penetration of cooking liquor into wood chips or grass raw materials, improving cooking efficiency and pulp yield | |
| Metal Surface Treatment | Alkaline degreasing cleaning | Acts as a penetrating component in metal cleaning agents, enhancing the penetration and emulsifying ability against oil stains on metal surfaces |
| Industrial Hard Surface Cleaning | Alkaline hard surface cleaning | Improves the penetrating power of alkaline cleaning solutions, helping to quickly break down and remove stubborn oil stains and dirt |
Alkali-resistant penetrant AEP is particularly suitable for harsh working conditions with high alkali, high temperature, and high electrolyte concentration. It is recommended that users conduct compatibility tests before actual use to optimize process formulations and dosage. This product can be used in the same bath with various auxiliaries, featuring a 'multi-purpose with one agent' characteristic, effectively simplifying processes, reducing the types of chemicals, and lowering overall operating costs.
In textile printing and dyeing, AEP performs exceptionally well in mercerizing penetration and alkali-peroxide one-bath scouring and bleaching processes; in the metal cleaning field, as a core penetrating component in alkaline degreasing formulations, it significantly improves cleaning efficiency.
