I. Characteristics of Water-Based Metalworking Fluids 1. Alkaline pH: 8 - 9.5. Although this is not the most suitable pH for microorganisms, it does not affect their rapid proliferation. 2. Temperature: The low temperature is sufficient to support the growth and reproduction of microorganisms, but not so high as to inhibit their growth. 3. Usually contains a high percentage of water. 4. The components contain sufficient nutrients.

In industrial systems such as coatings, adhesives, and metal processing fluids that contain water, microorganisms are the lurking "invisible destroyers". They quietly multiply, causing product spoilage, odor, stratification, performance degradation, and even leading to production line contamination and customer complaints.

Triazine is mainly used as a fungicide in natural latex to extend the storage time of latex and improve its quality. During the processing of natural latex,

biological stability of water-based metal cutting fluids in China In recent years, the biological stability of water-based metal cutting fluids has aroused widespread concern in the domestic industry, and domestic research has been conducted in this area

Hydroxyethyl hexahydrotriazine (hereinafter referred to as BK) preservatives as a commonly used fungicide
