According to the dissolving property, the HPMC can be mainly divided into 2 types. The instant dissolving type, which is widely applied in the detergent industry. Such as shampoo, liquid soap, dish washing detergent, tooth paste, cloth washing etergents, painting, capsule, etc. This type of HPMC can be dissolved into room temperature water, and with high permeability. It can act as thickener, excipient, emulsifier, film-forming agent and dispersant
These applications requires a very high standard type of HPMC, thus it shall have the following features:
Shall be dissovable in water under room temperature.
High permeability
Gain viscosity within 30-60 minutes
No stains after storage of several weeks
The other type is hot dissolving HPMC. This type only have quick dissolving effect under the condition of hot water above 60 ℃. This type of HPMC is mainly used in the construction, ceramic industry, textile industry etc. It can be used as thickener, water retention agent, prolonging the open time, ensures the mortar or wall putty to be anti-drooping, anti-cracking and improves the work-ability. The function of HPMC is very distinct.
Outdoor Block Bonding Mortar
EIFS Mortar.
Tile Adhesive Mortar.
Spray Gun Used Slurry
Tile Grout
Self-leveling Slurry
For plaster putty, anti-cracking.
Anti-powdering for wall putty.
Ash ratio check by burning
By weighing
The higher purity the higher density it is. So, we may use the same measuring cup, add into HPMC of same volume, and check the weight. The heavier, the purer. (Based on the same correct content.)
By checking the fluidity
The purer powder got a better fluidity. When we put it into a jar or glass, by rolling,we may judge the quality by the fluidity. Better quality type will be more smooth in fluidity.
Before bulk order, we suggest to check the quality first by samples. We provide free samples with the air shipping cost covered by the buyer. We may provide samples for different batches, for you to check our quality stability too.
