Slaodacht ghrád tógála HPMC increases when the temperature drops. The product viscosity we usually call refers to the result of the detection of a 2% aqueous solution of this product at a specific temperature of 20 degrees Celsius.
In practical applications, because of large temperature differences between summer and winter, our engineers recommend using relatively low Slaodacht ghrád tógála HPMC in winter, so that it is more convenient to use during construction and construction progress is faster. If high Slaodacht ghrád tógála HPMC is used and used in low temperature weather in winter, Slaodacht ghrád tógála HPMC will increase. When workers scrape, the viscosity is too strong, it is not easy to scrape, and it is uneven, which increases the difficulty of workers' work. , The progress of the project will also be affected.
But in summer, we can use high Slaodacht ghrád tógála HPMC so that the viscosity of the product will not decrease, the worker can be done it well.
