STPP-IC500 Industrial-Grade Sodium Tripolyphosphate FAQ
I. In-depth analysis of technical characteristics
Q1: How does a 57.8% P₂O₅ content improve industrial efficiency?
A: Ultra-high phosphorus content is achieved through a gradient calcination process:
Scale inhibition efficiency: For every 1% increase in P₂O₅, the amount of calcium ion chelation increases by 12mg/g (actually measured 352mg/g)
Economic efficiency: Compared with ordinary STPP, the dosage is reduced by 17%
Q2: What is the practical significance of the 18-second dissolution rate for the production process?
A: Breakthrough dissolution performance solves three major pain points:
① CIP system cleaning cycle is shortened by 40%
② The efficiency of on-site preparation of petroleum fracturing fluid is increased by 3 times
③ Avoid equipment wear caused by undissolved particles (particle size D90=18μm laser verification)
II. Industry application solution guidance
Q3: What is the compatibility in H₂S-containing oil and gas fields?
A: Through sulfide passivation technology:
Maintain 96% chelation efficiency in 200ppm H₂S environment (NACE TM0193 test)
The synergistic effect value of compounding with corrosion inhibitors reaches 1.42 (theoretical limit 1.45)
Q4: How do you work synergistically with a strong alkaline cleaning solution (pH>13)?
A: Unique process ensures alkaline stability:
The retention rate of active ingredients in 15% NaOH solution is >98% (72-hour test)
Recommended addition order: first add STPP-IC500 and stir for 5 minutes, then add alkali solution
Provide customized compatibility test kit (including pH buffer module)
III. Quality Verification and Safety Compliance
Q5: How do we confirm the authenticity of heavy metal content <2ppm?
A: Triple verification system:
Real-time monitoring: ICP-OES on the production line automatically samples every 30 minutes
Third-party review: SGS test report is provided with the goods (sample number can be checked on the official website)
Customer self-test: Heavy metal rapid detection kit (colorimetric method, results in 5 minutes)
