How to choose the appropriate hydroxypropyl methylcellulose (HPMC) for different applications?
Hydroxypropyl Methyl Cellulose, in English: Hydroxypropyl Methyl Cellulose, also known as HPMC or MHPC. Other names: Hydroxypropyl Methyl Cellulose; Cellulose Hydroxypropyl Methyl Ether; Hypromellose; Cellulose, 2-hydroxypropylmethyl Cellulose ether; Cellulose hydroxypropyl methyl ether; Hyprolose.
What are the other names for Hydroxypropyl Methyl Cellulose (HPMC)?
1. Whiteness: Although whiteness alone does not determine the usefulness of HPMC, higher-quality products usually have better whiteness.
2. Fineness: HPMC is typically available in 80 and 100 mesh sizes, with fewer options in 120 mesh. Finer particles generally indicate better quality.
3. Transmittance: When HPMC is dissolved in water and forms a transparent colloidal solution, higher transmittance indicates fewer insoluble impurities.
4. Specific gravity: Higher specific gravity is generally better. A higher specific gravity is often due to a higher content of hydroxypropyl, which results in better water retention.
HPMC is a non-ionic type of cellulose ether. So, what does "non-ionic" mean?
In the application of HPMC in putty powder, it plays three roles: thickening, water retention, and facilitating construction. Thickening: Cellulose can thicken the mixture, maintain uniform suspension, and prevent sagging. Water retention: It slows down the drying process of putty powder and assists in the reaction of lime and calcium in water. Construction: Cellulose acts as a lubricant, improving the workability of the putty powder. HPMC does not participate in any chemical reactions; it only serves as an auxiliary agent. When putty powder is mixed with water and applied to the wall, a chemical reaction occurs because new substances are formed. However, if the putty powder is scraped off the wall, ground into powder, and reused, it is not suitable because a new substance (calcium carbonate) has already formed. The main components of lime and calcium powder are Ca(OH)2, CaO, and a small amount of CaCO3. The reaction can be represented as: CaO + H2O = Ca(OH)2 — Ca(OH)2 + CO2 = CaCO3 ↓ + H2O. Under the action of water and carbon dioxide in the air, lime and calcium carbonate are formed. HPMC only assists in water retention and the better reaction of lime and calcium; it does not participate in any reactions itself.
How to judge the quality of HPMC?
1. Hot water dissolution method: HPMC does not dissolve in hot water, but it can disperse evenly in hot water initially and then rapidly dissolve upon cooling. There are two typical methods described as follows:
(1) Place the required amount of hot water in a container and heat it to approximately 70°C. Gradually add HPMC while stirring slowly. Initially, HPMC will float on the water's surface and gradually form a slurry, which cools down under stirring.
(2) Add 1/3 or 2/3 of the required amount of water to a container and heat it to 70°C. Disperse HPMC according to method (1) to prepare a hot water slurry. Then, add the remaining cold water to the hot water slurry and cool the mixture after stirring.
2. Powder mixing method: Mix HPMC powder with a large amount of other powdered substances using a blender. Afterward, add water for dissolution. In this case, HPMC can dissolve without clumping because each tiny corner of the powder contains only a small amount of HPMC, which dissolves immediately upon contact with water. This method is commonly used in putty powder and mortar production.
