When mixing refractory mud, the water temperature requirements are as follows:

I. Normal temperature water:

Usually, clean normal temperature water should be used when mixing refractory mud, and the water temperature is generally between 5℃ and 35℃. This is because normal temperature water can ensure the normal chemical reaction and physical properties of refractory mud, and at the same time avoid the influence of too high or too low water temperature on its cohesiveness and hardening effect.

II. Low temperature environment:

When the ambient temperature is lower than 5℃, in order to ensure the construction performance and hardening effect of refractory mud, the mixing water can be heated appropriately to ensure the proper temperature of the mud. However, it should be noted that the water temperature should not be too high to avoid affecting the chemical stability of refractory mud.

III. High temperature environment:

In the high temperature environment, it should be avoided to mix refractory mud with overheated water, because high temperature water may lead to the early reaction of binder in refractory mud and affect its construction performance.

IV. Water quality requirements:

No matter what the temperature, the water mixed with refractory mud should be kept clean, the water quality should meet the water standard for urban residents, and the chloride ion content in the water should be less than 300ppm. For coastal areas or areas with poor water quality, special attention should be paid to water testing to ensure that the chloride ion concentration meets the requirements.
