Why do putty and mortar made of cellulose with the same viscosity feel different in winter and summer?
Why do putty and mortar made of cellulose with the same viscosity feel different in winter and summer?
Due to the thermal gelation of the product, the viscosity of the product will gradually decrease with the increase of temperature. When the temperature exceeds the gel temperature of the product, the product will precipitate out of the water, thus losing its viscosity. The room temperature in summer is generally above 30 degrees, which is much different from the temperature in winter, so I feel the viscosity is lower. It is suggested that products with a higher viscosity should be selected as far as possible in product application, or the amount of cellulose should be increased. In addition, products with high gel temperature should be selected, and cellulose produced by our company should be selected as much as possible. The gel temperature of products is generally above 70 degrees. Try not to use methyl cellulose in summer, because its gel temperature is about 55 degrees Celsius, and its viscosity will be greatly affected if the temperature is slightly higher.
