What problems should be paid attention to in the production of hydroxypropyl methylcellulose in putty powder

We know that hydroxypropyl methylcellulose is a powdery substance at room temperature, and the powder is relatively uniform, but when you put it in water, the water will become viscous at this time, And with a certain degree of viscosity, we can correctly identify it by using the characteristics of hydroxypropyl methylcellulose, and general construction sites will generally adapt to such a characteristic of it, let the rest of the putty powder combine to increase The stickiness between the putty powder and the wall surface, so what details should be paid attention to when adding hydroxypropyl methylcellulose to the putty powder?

Once any powder is to be made into a solution, there must be a certain dosage requirement, and the use of hydroxypropyl methylcellulose is no exception. When making a mixed solution with putty powder, its dosage generally depends on the external temperature, environment, The quality of local ash calcium is closely related to these factors. Generally, other putty powder solutions need to be prepared. Generally, people will use hydroxypropyl methylcellulose between 4 kg and 5 kg, but generally the amount used in winter is higher than that in summer. It should be less. When you make a mixed solution, you can sum it up carefully.

Moreover, when the mixture solution is prepared in different regions, the dosage is also different. For example, to prepare the solution in a certain region of Beijing, it is generally necessary to add 5 kg of HPMC. But this amount is also for summer, and 0.5 kg less in winter; but in areas like Yunnan, when making the solution, generally only need to put 3 kg – 4 kg of HPMC, the dosage It is much less than Beijing, and the environment is different, and there will be differences in the natural amount.
