How is DTPMPA used in papermaking?

 DTPMPA (pentamethylamine pentaphosphate) is mainly used as chelating agent and scale inhibitor in paper industry, the following are its specific applications:

Chelating agent:

Prevent metal ions from interfering: in papermaking process, water often contains metal ions such as calcium, magnesium, iron, etc. These ions will interfere with the performance of papermaking chemicals.DTPMPA combines with these metal ions through chelating, preventing them from reacting with other chemicals in the pulp and ensuring the smooth progress of papermaking process.

Improvement of paper quality: Chelating metal ions prevents them from negatively affecting the fibres, thus improving the strength and whiteness of the paper.

Scale inhibitor:

Prevents scaling: In papermaking water systems with high water hardness, precipitates such as calcium carbonate and calcium sulphate are easily formed, leading to scaling of the equipment.DTPMPA can prevent calcium and magnesium ions from precipitating by complexing them, protecting the equipment and pipelines, and reducing maintenance costs.

Improve heat exchange efficiency: By preventing scaling, DTPMPA is able to maintain the efficiency of heat exchangers, saving energy and improving productivity.

Anti-corrosion agent:

Extend equipment life: DTPMPA has good anti-corrosion properties that prevent corrosion of piping and equipment, extending their life and reducing downtime and maintenance costs.

Overall, the application of DTPMPA in the paper industry not only improves the quality of paper, but also effectively reduces production costs and improves production efficiency.

多元醇磷酸酯 PAE

  Performance and Usage : PAPE is a novel water treatment chemical with good scale inhibition and corrosion resistance properties. The introduction of multiple polyoxyethylene groups in the molecule enhances its corrosion resistance and the ability to disperse calcium scale and suspended solids. It effectively inhibits the deposition of barium and strontium scales, which are challenging for existing scale inhibitors, and also provides excellent scale inhibition for sparingly soluble salts like calcium carbonate and calcium sulfate. PAPE offers cathodic protection for steel and is more effective than similar products available domestically. It is miscible with polycarboxylate, organophosphonates, inorganic phosphates, and zinc salts, making it versatile for use with other water treatment agents. The product is suitable as a scale inhibitor for oilfield water injection and as a corrosion and scale inhibitor for circulating cooling water treatment. Technical Specifica...

What is the function of EDTMPS

 EDTMPS， Ethylenediamine tetramethylphosphonic acid sodium is a nitrogen-containing organic polybasic phosphonic acid mainly used as a cathodic corrosion inhibitor. Compared with inorganic polyphosphates, it has a higher corrosion inhibition efficiency, about 3 to 5 times higher. EDTMPS is miscible with water, non-toxic and pollution-free, with good chemical stability and temperature resistance, and can maintain its scale inhibition effect even at high temperatures of 200 ℃. In aqueous solution, EDTMPS can dissociate into 8 positive and negative ions, forming chelates with multiple metal ions, thereby disrupting the normal crystallization of calcium scale and exhibiting good scale inhibition effects on calcium sulfate and barium sulfate scales. The main uses of EDTMPS include as a corrosion and scale inhibitor for circulating water and boiler water, a chelating agent for cyanide free electroplating, a chelating agent for the textile printing and dyeing industry, and a...
