Product Description

Product Description

Principle of Gypsum hardening accelerator
Gypsum coagulant is a chemical agent that can accelerate the curing time of gypsum. The principle is that the addition of gypsum coagulant can inhibit the diffusion of calcium ions in gypsum and promote the aggregation of calcium ions, so that the reaction speed of gypsum is accelerated and the curing time is shortened.

Influence and advantages of Gypsum hardening accelerator
1. Influence on curing time: adding gypsum coagulant can shorten the curing time of gypsum, especially for the products that need to be processed such as large pieces of gypsum and gypsum sculpture, it can improve the production efficiency.
2. Improve the performance of gypsum: gypsum coagulant can make the surface of gypsum smoother, improve the hardness, toughness and strength of gypsum, and improve the quality and service life of products.
3. Enhance the waterproof performance: the use of gypsum coagulant can make the gypsum form a more dense structure after curing, improve the waterproof performance.
4. Improve the added value of commodities: the application of gypsum coagulant can speed up the production speed of gypsum products and improve the added value of commodities.

Precautions for the use ofGypsum hardening accelerator
1. Use it strictly according to the added amount, don't add too much.
2. Gypsum coagulant should be sealed and stored, avoid moisture and sun exposure.
3. Gypsum coagulant should avoid direct contact with skin and eyes, wear protective gloves and glasses when using.
4. The material should be cleaned in time after use.


SF-15C
Gypsum quick-hardening additives Gypsum hardening accelerator

Gypsum hardening aid is a chemical agent that can accelerate the curing time of gypsum. The principle is that the addition of gypsum coagulant can inhibit the diffusion of calcium ions in gypsum and promote the aggregation of calcium ions, so that the reaction speed of gypsum is accelerated and the curing time is shortened. SF-15 is a special coagulant for gypsum, which can accelerate the hardening process of gypsum-based materials in contact with water.

 

Product characteristics

SF-15 has good dispersion and workability.

1. SF-15 is a powder composite material, which can be mixed in gypsum or dissolved in water, with good water solubility.
2. Affect the curing time: adding gypsum coagulant can shorten the curing time of gypsum, especially for the products that need to be processed such as large pieces of gypsum and gypsum sculpture, it can improve the production efficiency.
3. Improve the added value of commodities: the application of gypsum coagulant can accelerate the production speed of gypsum products and improve the added value of commodities.
4. It can be used with water reducing agent to accelerate the setting time.

 

Technical Data

Recommended dosage0.05% ~ 0.5% of total volume, according to the type of raw material and the demand for appropriate mixing to determine the appropriate dosage.

Scope of application

1. Gypsum products such as gypsum board, art gypsum, gypsum self-leveling, etc.
2. Gypsum sculpture
3. Gypsum works
4. plaster cast
5. Construction

Usage and Precautions

1. When using, need to be mixed with other dry powder components together, when using according to the construction of different areas of mixing requirements for mixing and construction;
2. Before using gypsum coagulant promoter, it is first necessary to add appropriate amount of coagulant promoter in the ratio of gypsum and water. Generally, the amount of gypsum coagulant is0.05% ~ 0.5% of the weight of gypsum. Then mix well to form gypsum slurry. After the slurry is prepared, it should be used in time so as not to waste the gypsum because it cures too fast.;
3. The mixing amount of concrete with higher requirements for freeze-thaw resistance and winter construction concrete should be determined by test according to the requirements of air content of concrete.
4. The air-entraining quantity is affected by the material used to formulate concrete and the temperature of the environment in which the concrete is prepared, so it must be kept as stable as possible in order to control the fluctuation of air content.

packaging and storage

1. Packed in paper-plastic composite bag, 25kg/bag, the storage period is 12 months from the date of production, if it exceeds the shelf life, it must be verified by test and inspection before use;
2. Place in a ventilated and dry place for storage, pay attention to moisture-proof treatment, avoid direct sunlight, use it in time after opening, and seal it in time if it is not used up to prevent moisture absorption and deterioration.
