The usage method of high temperature penetrant JFC-M varies depending on the application process. The database does not provide a fixed universal dosage; the optimal amount needs to be determined through small-scale tests based on specific working conditions.

Detailed Explanation

High temperature penetrant JFC-M (Isotridecanol polyoxyethylene ether), as a nonionic surfactant, has well-established usage methods in multiple industrial fields due to its excellent penetration, wetting, and high temperature resistance (cloud point 85~95°C), as well as alkali resistance (can withstand up to 200g/L NaOH).

Regarding Usage Method: The most core usage of this product is direct addition to various industrial liquid baths (such as dyeing baths, pretreatment liquids, and cleaning tanks). In the textile printing and dyeing field, it is mainly used as a penetrating leveling agent for high-temperature and high-pressure dyeing. It is typically injected into the circulation system along with dyes and auxiliaries during the preparation of the dye liquor; in pretreatment processes such as desizing and scouring, it can be used in the same bath as chemicals like caustic soda and hydrogen peroxide to promote the penetration of the chemical solution into the fiber interior. In metal cleaning, it serves as one of the core components of the cleaning solution and is directly added to the cleaning formulation. Regardless of the application, it is recommended to add it while stirring slowly to ensure uniform dispersion.

Regarding Recommended Dosage: The Guoli Chemical database does not specify the specific addition ratio of this product in the production process. This is because the optimal dosage highly depends on the type of material being treated, equipment type (such as overflow dyeing machines, jig dyeing machines), working fluid temperature, contact time, and final performance requirements. As an industry general reference, the initial trial range for nonionic penetrant products in general industrial working fluids is typically between 1~5 g/L, but this is not an official recommendation from Guoli Chemical and serves only as a starting point for exploration. It is strongly recommended that users combine on-site process conditions, start with a low dosage and conduct gradient small-scale tests to balance penetration effect and low foaming performance, thereby determining the precise dosage that best suits your needs.

Application Suggestions

According to the application fields provided by the Guoli Chemical database, high temperature penetrant JFC-M exhibits outstanding performance in the following scenarios:

  • Textile Printing and Dyeing High-Temperature and High-Pressure Dyeing: Used as a penetrating leveling agent added to the dye bath, it can quickly carry the liquid and penetrate into the interior of yarns or fabrics, improving dye uptake and levelness, especially suitable for difficult-to-penetrate materials such as package yarns and hank yarns.
  • Textile Pretreatment (Desizing/Scouring/Bleaching): Promotes the penetration of alkali liquor and oxidizing agents into the fiber interior, enhancing the removal rate of sizing agents and whiteness, and shortening processing time.
  • Leather Processing: Used in soaking and degreasing processes to accelerate the softening of dried hides and enhance the emulsification and removal of natural fats.
  • High-Temperature Metal Cleaning: Quickly penetrates to the interface between oil stains and metal at high temperatures, efficiently stripping carbon deposits and rust scale.
  • Pesticide Synergist: Used as a tank-mix adjuvant to reduce the surface tension of the spray solution, improving the wetting, spreading, and absorption on target crops.

Precautions

  • Eye Protection: This product is moderately irritating to the eyes. Chemical safety goggles must be worn during operation to prevent splashing.
  • Dilution Operation: The viscosity of the product may increase due to low temperatures. If the material becomes thick during winter use, it should be moved to a warm environment to naturally restore fluidity before use.
  • Incompatibility: Although this product is resistant to acids and alkalis, direct contact with strong oxidizing agents should be strictly avoided during operation to prevent violent reactions.
  • Wastewater Treatment: Wastewater containing the product should be collected and treated; it must not be directly discharged into sewers or natural water bodies without dilution.
