2. Scope and performance

This series is mainly suitable for Portland cement, ordinary Portland cement, composite Portland cement, slag Portland cement, pozzolanic Portland cement, fly ash Portland cement and masonry cement.

According to its function, it is divided into early strength type, late strength type, production-increasing type, comprehensive type, retardation type and other products.

Early-strength products, used in the cement production process, can improve the 3-day compressive strength of cement by more than 4.0MPa under the condition that the cement ratio and fineness control indicators are basically the same, and the increase in water demand for standard consistency of cement is less than 0.5%. ;

The post-strength product is used in the cement production process. Under the condition that the cement ratio and fineness control indicators are basically the same, the 28-day compressive strength of the cement can be increased by more than 8.0MPa, and the increase in water demand for the standard consistency of the cement is less than 0.5%. ;

The production-increasing product is used in the process of cement production by tube mill. Under the condition that the cement ratio and fineness control indicators are basically the same, the hourly output of the cement mill can be increased by more than 15%;

Comprehensive product, used in the cement process, under the condition that the cement ratio and fineness control indicators are basically the same, it can reduce the amount of cement clinker by more than 6%, increase the amount of mixed materials in the same proportion, and can increase production by more than 8%. ;

The retarded product is used in the production of retarded cement. When the cement ratio and fineness control indicators are basically the same, the initial setting and final setting time of this grinding aid can be extended by more than 120 minutes, and the cement is 3 days. , 28-day compressive strength increased by more than 0.5MPa.

4. Characteristics of cement using this grinding aid

1. The fluidity of cement powder will increase;

2. The fluidity of cement mortar increases slightly;

3. The water consumption of standard consistency will vary due to the amount and variety of mixed materials;

4. It is more sensitive to use a 45μm sieve to control the fineness of the milled cement.

5. How to join when using

You can directly use the metering pump to meter in without raising the addition height;

When it is necessary to increase the feeding height of grinding aid, it is generally added by means of secondary pumping, as shown in the diagram below:

For companies that use our grinding aids, we provide customers with storage tanks and related metering devices and methods of testing and controlling the amount of feed.

6. Precautions

1. This grinding aid should be used after passing the inspection. Acceptance inspection methods are:

1) A relatively simple method is to detect the density, PH value and color, or solid content of the newly arrived grinding aid and the retained sample of the certified grinding aid under the same temperature conditions, when the two are within the error range. It can be considered qualified and put into use within the time limit;

2) Use a kind of additive-free cement with the same composition as the production cement, and at the same time in the same laboratory, use the retained sample of the grinding aid confirmed by the use certificate and the newly arrived grinding aid to sample the cement strength blending test. When the three-day strength of the two is within the error range, it is qualified; the first method is generally used when the grinding aid is used continuously, and the second method is only used when there is a big difference in the quality of the grinding aid.

2. The grinding aid should be prevented from being dropped, smashed, squeezed by external force and approaching high temperature during handling and storage, and the stacking height should not exceed two barrels;

3. Before use, check the company's logo and then open the cover to confirm that the product and model are correct before putting it into use;

4. This product is slightly corrosive to the skin. After contact with the skin, it should be washed with water, and it should not be eaten by mouth;

5. When using this product, when the ambient temperature is lower than -5°C for 5 consecutive days, insulation measures should be taken to prevent product crystallization from affecting normal use.

6. The shelf life of this product is: 12 months.
