  🧫 Struggling with iron fouling and phosphate scale in your RO or cooling system? Traditional dispersants often fall short when it comes to complex scale and fouling combinations. You need a copolymer engineered for the toughest conditions. Shandong Kairui Chemical’s AA-AMPS Copolymer (Acrylic Acid – 2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer) offers advanced performance: ✅ Superior iron dispersion – effectively disperses iron oxide and prevents deposition ✅ Calcium phosphate scale control – outperforms conventional polymers in phosphate-rich systems ✅ Excellent calcium carbonate inhibition – keeps heat exchangers and membranes clean ✅ Chlorine resistance – maintains performance even in chlorinated systems ✅ Compatible with multiple water chemistries – adaptable to a wide range of industrial applications 🌊 Ideal for: cooling water systems, reverse osmosis pretreatment, boiler water, and oilfield produced water treatment. 💡 Recommended dosage: 2–15 mg/L depend...

 If you're running a reverse osmosis (RO) system, you know the struggle: membrane fouling, frequent cleaning, and that constant battle with scaling. It eats into your budget and cuts into your production time. That's where KR-191 RO Membrane Scale Inhibitor & Dispersant from Shandong Kairui Chemistry comes in. ✅ What it does: KR-191 is a high-performance scale inhibitor widely used in brackish water, high-salinity water, process water, and even drinking water systems . ✅ Why it matters: It delivers powerful scale inhibition across various water qualities, reduces the frequency of membrane cleaning, and can even minimize or replace acid dosing in your system . ✅ The result: Lower chemical costs, higher water recovery rates, and extended membrane life . Don't let scale steal your efficiency. KR-191 works with all membrane types and is more stable and effective than traditional SHMP (sodium hexametaphosphate) . 👉 Learn more: www.krwater.com 📧 Contact: e...

 HPMA is a low molecular weight polymeride, with average molecular weight 400-800. No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature above 330℃.HPMA has obvious threshold effect under high temperature (350℃) and high pH(8.3)level, suitable to be used in alkaline water system or built with agents. It has good scale inhibition against carbonate and phosphate scales under temperature 300℃ with effective time as long as 100 hours. Due to its good scale inhibition and high temperature tolerance properties, HPMA is widely used in desalination plant of flash vaporization equipment, low pressure boiler, steam locomotive, crude oil evaporation, petroleum pipeline, and industrial circulating cool water systems. In addition, HPMA has good corrosion inhibition effect when used together with zinc salt. HPMA can also used as additives for cement. HPMA is usually used together with organic phosphonate at dosage of 1-15ppm for circul...

  PAPE is a new variety of water treatment chemical. PAPE has very good scale and corrosion inhibition ability. Because more than one ployethylene glycol group is introduced into the molecule, the scale and corrosion inhibition for calcium scale is improved a lot. PAPE has wonderful inhibition effect for barium and strontium scales. PAPE has admirable scale inhibition capacity for calcium carbonate and calcium sulfate,PAPE can be mixed well with polycarboxylic acid, organophoronic acid, phosphate and zinc salt. PAPE can also be used as scale inhibitor for oilfield and industrial cool water system.

  CAS No. 9003-04-7 corresponds to  Polyacrylic Acid  ( PAA ). PAA is an important polymer compound, produced by polymerization of acrylic monomer, which is water-soluble and has various functionalities, and is widely used in industry and daily life. This is a highly versatile polymeric compound with the molecular formula (C₃H₃NaO₂)ₙ. Depending on the application and form, it is also known as polyacrylic acid sodium salt, PAAS, or other trade names.
