 KR-0100 is a universal composite reverse osmosis membrane antiscalant developed for most industrial desalination, pure water preparation and small seawater desalination equipment. It adopts the compound formula of organic phosphonate and sulfonate copolymer, and realizes three core scale inhibition mechanisms of metal ion chelation, crystal lattice distortion and particle dispersion at the same time. It can comprehensively inhibit the precipitation and scaling of calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate and silica, covering almost all common scaling substances in reverse osmosis influent water. The formula is mild and friendly to membrane materials; it can be safely used for TFC polyamide composite membranes and CA cellulose acetate nanofiltration membranes, and will not cause irreversible surface pollution and damage to the membrane layer. The applicable pH range of KR-0100 is 5 to 10, which can adapt to raw water with high hardness and low hardness. ...

  CAS 130668-24-5 – PAPEMP is an advanced macromolecular organic phosphonic acid with molecular weight approximately 600, specifically developed for challenging water treatment conditions. The compound exhibits exceptional calcium tolerance at high concentration multiples, providing superior scale inhibition for calcium carbonate, calcium sulfate, and calcium phosphate. CAS 130668-24-5 demonstrates outstanding dispersing performance for iron oxides, iron hydroxides, and zinc hydroxides, making it particularly effective in high-iron and high-turbidity systems. The compound chelates effectively with copper, calcium, and magnesium ions forming soluble complexes, supporting applications in cooling water systems, household detergents, thermal power plants, and oilfield operations. The product shows excellent synergistic effects with other water treatment chemicals including HPAA and ATMP, especially under conditions of high hardness, high turbidity, high pH, and high co...

  High-temperature water systems, such as boilers and certain closed-loop cooling applications, impose extreme stress on water treatment chemicals. Elevated temperatures accelerate chemical breakdown and can significantly reduce the efficacy of standard scale and corrosion inhibitors. Shandong Kairui Chemical has developed a range of products specifically engineered to maintain their performance under these challenging thermal conditions 。 Phosphonates like  1-Hydroxy Ethylidene-1,1-Diphosphonic Acid  are known for their excellent thermal stability, making them a preferred choice for high-temperature applications. This stability ensures that the active scale-inhibiting molecules remain intact and functional, providing long-term protection against calcium carbonate and sulfate deposits. Furthermore, Kairui’s proprietary polycarboxylic acid polymers and specialized copolymers are designed to withstand high temperatures without losing their dispersant properties...
