Degree of substitution

The degree of substitution is the average level of methoxy substitution on the cellulose chain. Since there are maximum three possible sites of substitution with each cellulose molecule, this average value is a real number between 0 and 3. However, the degree of substitution is often expressed in percentages.

Molar substitution

Molar substitution is the average level of hydroxypropoxy substitution on the cellulose chain. Since hydroxypropoxy base can be attached to each other on side chains and does not each require a base substitution site on the cellulose molecule, this number can be higher than 3. However, molar substitution is also often expressed in percentages.

Customization

HUAMAO® can customize according to customer demand, production of goods.
1. HUAMAO® can customize the packaging according to the customer's requirements.
2. HUAMAO® can produce HPMC which is the special technical index, according to the customer's demand.

Ceramic tile as a functional decorative material, has been widely used throughout the world, and how to paste this durable material has always been a concern, the appearance of ceramic tile adhesives to a certain extent to ensure the reliability of the bond engineering, Tile has different shapes and sizes, unit weight and density also have differences, The cellulose ether products of Shandong Heta can guarantee the smooth construction of different types of tiles on different substrates, even when the environment temperature is relatively high, it can also give the tile binder long opening time and adjustable time.

Due to the problem of habit, in the way of construction, Europe and China have a large difference, different construction habits for tile binder is different requirements. In China, the point sticking method is still the main method of tile pasting project, when using the point sticking method, it is easy to stir, easy to operate, not stick the knife in the first place for tile binder, and have good anti drape effect; When the pasting method is changed into a trowel, the requirements for tile Binder are: Easy to stir, easy to spread, non-stick knife, good resistance to drape, long opening time, good wettability, adjustable time.

The requirements of different construction methods can be easily achieved by adding different cellulose ether products, and the cellulose ether from Shandong Heta can provide excellent wet adhesion, sag resistance and opening time for your tile binder.
