Abstract

The invention provides an automatic test method and instrument for modules of sodium silicate, so as to solve the problems that in the existing measuring method, naked eyes are adopted to judge the titration end point, the measuring precision is low, and the manual operation is adopted, back titration is required to be carried out on sodium hydroxide solution in the measuring process, and the test cycle is longer. In the invention, an electric potential signal collected by a pH electrode is adopted to replace the naked eyes to judge the titration end point, manual liquid-adding titration is replaced by accurate liquid-adding titration carried out by an accurate liquid-adding titration apparatus, a processor is adopted to control the titration process and processing data, and a magnetic force heating stirrer is adopted to heat and stir in the whole measuring process. The instrument in the invention consists of a liquid-adding titration unit, a reaction unit, a signal acquisition amplifying unit, a data processing unit and a result output unit. By utilizing the method and instrument provided by the invention, rapid and accurate measurement of modules of the sodium silicate is realized, and the labor intensity of experimenters is alleviated.

Description

technical field

[0001] The invention relates to a water glass modulus measuring technology, in particular to a method and an instrument capable of automatically measuring the water glass modulus. Background technique

[0002] Water glass, also known as sodium silicate, chemical name is sodium silicate, molecular formula is Na 2 O nSiO 2 ·xH 2 O. Water glass is cheap, abundant in sources, colorless, odorless, and non-toxic. It is used in the chemical industry to manufacture silica gel, white carbon black, zeolite molecular sieve, sodium metasilicate, silica sol, layer silicon, and instant powdered sodium silicate. , Potassium sodium silicate and other silicate products are the basic raw materials of silicon compounds. In the light industry, it is an indispensable raw material for detergents such as washing powder and soap, and it is also a water softener and sedimentation aid; it is used in dyeing, bleaching and sizing in the textile industry; it is widely used in casting...
