Scale and Corrosion Inhibitor MST210

I. Performance and Application MST210 closed-loop water corrosion inhibitor is suitable as a corrosion and scale inhibitor for chilled water and hot water systems of central air-conditioning closed systems. MST210 closed-loop water corrosion and scale inhibitor is mainly composed of small-molecule organic phosphonate corrosion inhibitors, dispersants, molybdate, etc., and is one of the more widely used scale and corrosion inhibitors with good performance in closed systems. It has good corrosion inhibition performance on carbon steel, stainless steel, copper alloy, aluminum alloy and other materials, has good scale inhibition performance in closed hot water systems, contains no chromate, is colorless in water, and reduces the phenomenon of spotting on metal materials. It ensures good heat transfer efficiency and reduces maintenance and operating costs. The liquid product is very convenient to add and operate. This product is suitable for closed circulating water cooling systems with small leakage. II. Technical Indicators Appearance: reddish-brown transparent liquid Active ingredient ≥: 20% Density (20°C) g/cm3 ≥: 1.1 pH (1% aqueous solution): -10 III. Usage Based on the system's holding water volume, add 15-25 g per ton of water. There are two dosing methods: first, during normal operation, based on the make-up cooling water volume, add 1.3 times the calculated dosage into the expansion tank. Second, use a metering dosing pump: pour the agent into the dosing tank, add seven times the amount of water, and dose daily an amount equal to the tonnage of make-up water multiplied by eight. IV. Packaging and Storage MST210 closed-loop water corrosion and scale inhibitor is packed in plastic drums, 25 kg or 250 kg per drum. Store indoors in a cool place; storage period is twelve months. V. Safety and Protection MST210 closed-loop water corrosion and scale inhibitor is alkaline. Pay attention to labor protection during operation and avoid contact with skin and eyes. After contact, rinse with plenty of water.
