Detergent AR-812 is mainly used in three major industries: textile printing and dyeing, industrial cleaning, and papermaking, covering various processes such as desizing and scouring, dyeing soaping, metal degreasing, hard surface cleaning, and papermaking felt maintenance.

Detailed Description

Detergent AR-812 is a non-ionic surfactant with fatty alcohol polyoxyethylene ether as the main component. It is widely used in multiple industrial fields due to its excellent penetration, emulsification, and dispersion capabilities. Its non-ionic nature allows it to maintain stable cleaning performance under acidic, alkaline, and hard water conditions, and it is compatible with anionic, cationic, and other non-ionic auxiliaries for blending, giving it a very wide process adaptability range.

In the textile printing and dyeing industry, Detergent AR-812 runs through multiple processes including pretreatment, dyeing, and finishing. In the industrial cleaning field, its rapid emulsification of oil stains and anti-redeposition ability are particularly outstanding, making it an ideal choice for metal processing and hard surface cleaning. In the paper industry, it mainly plays a key role in felt maintenance, helping to extend felt service life and reduce maintenance costs.

The product also features low toxicity, non-irritation, non-flammability, easy biodegradability, and is APEO-free, fully complying with international environmental regulations and suitable for modern industrial production scenarios with strict requirements for safety and environmental protection.

Industry Application and Process Details

I. Textile Printing and Dyeing Processing Field

1. Cleaning of Cellulosic Fibers and Their Blended Fabrics
Used after pretreatment processes such as desizing, scouring, and bleaching to efficiently remove residual sizes, impurities, and decomposition products from the fabric, providing a clean substrate for subsequent dyeing and printing, ensuring uniform dye uptake.

2. Soaping of Dyed and Printed Fabrics
Suitable for the soaping process after dyeing and printing with reactive dyes, disperse dyes, vat dyes, effectively removing unfixed floating dyes and residual pastes, significantly improving fabric color fastness and color brightness, and preventing staining on white grounds.

3. Scouring of Synthetic Fibers and Their Blended Fabrics
Used for scouring and deoiling treatment of synthetic fiber fabrics such as polyester and nylon, rapidly emulsifying and removing spinning oils and oil stains contaminated during weaving, improving fabric hand feel and hydrophilicity.

II. Industrial Cleaning Field

1. Oil Removal and Degreasing of Metal Parts
Surface cleaning of workpieces, stamping parts, precision components to thoroughly remove various oil stains such as cutting fluids, rust preventives, and greases, meeting cleanliness requirements for subsequent electroplating, coating, and assembly processes. Also suitable for inter-process cleaning and surface treatment before coating.

2. Hard Surface Oil Cleaning
Applicable for heavy oil cleaning on hard surfaces such as mechanical equipment shells, industrial vehicles, workshop floors, and workbenches. Strong penetration and emulsification ability can quickly break down stubborn grease, with excellent anti-redeposition performance.

III. Paper Industry Field

Paper Machine Felt Washing and Maintenance
Used for online or offline washing of paper machine felts, effectively dissolving and removing deposits such as resin, stickies, fine fibers, and fillers accumulated in the felt, restoring felt breathability and elasticity, extending felt service life, and reducing the frequency of shutdowns for replacement.

Application Recommendations

  • Textile Printing and Dyeing: Recommended dosage of 1-3 g/L in pretreatment washing processes; adjust to 0.5-2 g/L in soaping processes depending on the degree of floating color, better effect when used with warm water (40-60°C).
  • Metal Cleaning: Recommended to prepare a 3%-10% working solution, using immersion, spray, or ultrasonic cleaning methods, with heating (50-70°C) to significantly improve oil removal efficiency.
  • Hard Surface Cleaning: Can be diluted 5-20 times depending on the degree of oil contamination, used with scrubbing or high-pressure rinsing.
  • Paper Machine Felt Washing: Continuous washing recommended dosage of 0.5-1.5%, intermittent washing can be increased to 2-3%, specific dosage adjusted according to felt contamination level.

Precautions

  • It is recommended to wear chemical safety protective gloves and goggles during operation, avoid long-term repeated skin contact to prevent degreasing and drying.
  • Avoid contact with strong oxidizers during use and storage to prevent violent reactions.
  • Recommended storage temperature is 5°C to 40°C, avoid direct sunlight, keep container tightly closed.
  • The product is APEO-free and complies with international environmental regulations, but waste liquid should be properly treated and not discharged directly into natural water bodies.
