HL-102 Hydroxyethyldiphosphonic acid HEDP
Properties:
Itis an organic dirt -resistant corrosion agent, which has the characteristics ofhigh temperature resistance, high pH value, not easy to hydrolysis, goodantioxidant performance, etc. It can form stability with various metal ionssuch as calcium, magnesium, copper, zinc, iron, aluminum, etc. When completingthe complex of the collateral, it shows a good synergy effect when it isreproduced with other water treatment agents. It is a commonly used stains inthe industrial circulating cooling water system. It can dissolve oxides on thesurface of the metal surface, and often serve as metal and non -metal cleaningagents.

Usage:
Ithas excellent stabilization corrosion performance, which is widely used inindustrial circulating cooling water systems such as metallurgy, coal chemicalindustry, and electricity, as well as medium and low -pressure boilers,oilfield water injection and oil pipelines. It is a boiler and heat exchanger.Salvas and corrosion agents can be used as metal and non -metallic cleaningagents, stabilizers and fixing agents in the drift -dyeing industry.
Itis used as a stuffing agent, and the concentration is generally controlled at 1~ 10 mg/L; used as a corrosion agent, the concentration is generally controlledat 10 ~ 50 mg/L; used as a cleaner, the concentration is generally controlledat 1000 ~ 2000 mg/ L; Usually use it with polycarboxylic acid -type dirtdispersing agent.
Packingand storage:
Thenet weight 25ibc or 250ibc plastic barrel is stored in a cool and dry place for ayear of storage.
SafetyProtection:
Itis acidic liquid. It is forbidden to contact the skin, eyes and clothing, andrinse it with a lot of water immediately after contact. Avoid inhalation ofsteam or smoke, container guarantee.
