应用
Mortar, plasters, cements, gas manufacturing to remove ammonia, in lubricants, water softening, petrochemicals, soil conditioner, paving materialsCalcium hydroxide is used as a flocculant in water and sewage treatment. It is also used in fresh water treatment to raise the pH of the water thereby controlling the corrosion of pipes. It is widely used in the production of calcium stearate. It is an active ingredient in whitewash, mortar and plaster. This compound is also used in the petroleum refining industry for the preparation of additives to oils and in the preparation of dry mixes for painting and decorating. It finds application as an antifungal and antimicrobial preservative for vegetables in storage.

产品说明

一般描述

The pH buffer standards are measured and qualified using differential potentiometry with two platinum hydrogen electrodes. This method allows the comparison of the reference buffers to the corresponding primary reference materials by PTB (Physical Technical Institute, Germany) and NIST (National Institute of Standards and Technology, USA). Uncertainty data and traceability are documented in a comprehensive, batch-specific Certificate of Analysis.

应用

For the preparation of DIN 19266 pH standard buffer solutions.
Calcium hydroxide (calcium dihydroxide or Ca(OH)2) is a reference buffer solution used to calibrate pH electrodes and pH instruments.
