Product Description

Product Description

SH-F3
Mortar suspending agent SH-F3 anti-sinking agent 

Cement-based self-leveling mortar has increasingly occupied an important position in floor materials due to its high fluidity, convenient construction, fast drying and hardening, and high strength. However, in actual applications, self-leveling often has phenomena such as bleeding and sedimentation, which not only directly causes the surface to become white and flowery, but also significantly reduces the strength after hardening.

 Common causes of bleeding and sedimentation
As one of the most complex systems in dry mortar, the formula design and selection of raw materials have a great impact on the final quality of self-leveling mortar. From the perspective of formula and raw materials, the common factors causing bleeding and sedimentation mainly include the following aspects:

(1) Ratio of powder to river sand
If the amount of cementitious material and fine filler is too low and the amount of river sand is too high, the slurry dispersed by the water reducer cannot fully wrap the river sand, which is easy to cause the sedimentation and bleeding of heavier particles.

(2) Grading of river sand
When the overall grading of river sand is coarse and the particles are heavy, the river sand particles are more likely to sink to the bottom of the mortar due to their own gravity. When the gradation and mud content of river sand vary greatly between batches, it will also cause a large difference in the flow state of the product, which is easy to cause water seepage and sedimentation.

(3) Water reducer
If the water reducer in the self-leveling mortar is not efficient, the cementitious material cannot be effectively dispersed, and workers often add excessive water to improve the fluidity of the slurry during construction. At this time, water seepage and sedimentation are likely to occur.
Ideas for solving water seepage and sedimentation
From the above analysis, it can be seen that when preparing self-leveling mortar, on the one hand, it is necessary to optimize the ratio of fine powder and river sand and strive to control the quality of river sand; on the other hand, water reducers and cellulose ethers with excellent performance should be selected and used. By adding stabilizers and other materials to appropriately improve the suspension of slurry particles, the sedimentation of self-leveling slurry can also be effectively improved. Stabilizers have the function of preventing mortar from water seepage, segregation and sedimentation, which helps self-leveling mortar form a more uniform structure, thereby improving bonding strength.

Mortar suspending agent SH-F3 anti-sinking agent

SH-F3 is a new suspending agent developed to solve the problems of high flow mortar, concrete easy to secrete, sand and gravel settlement. It can ensure the mortar or concrete with high fluidity and at the same time good integrity and uniform distribution of sand and gravel.

Product characteristics

1. Thickening effect: By increasing the system viscosity, increasing the resistance of the particle material to sedimentation, reducing the sinking movement, and thus playing a role in suspension stability.
2. Forming a grid structure: Some suspending agents themselves have a certain network structure or form a grid structure through hydration, adsorption, etc. This structure has a certain supporting effect, which can prevent the sedimentation of particles and improve the suspension capacity.
3. Increasing static shear force: When cement mortar is stirred by shear force, it will not settle, but when it is stationary, the gravity is greater than other forces and it will sink naturally. Adding a suspending agent will make the cement mortar have a certain thixotropy. When the external force stops, a colloidal structure with a certain gel strength will be formed to prevent the particles from settling.

2. Grouting material, compression slurry agent, etc.
3. Fluidity concrete.

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. The recommended dosage is  0.001~0.03% by weight of material, and the specific dosage is determined by trial mixing according to the application system and the change of dry mix components;

3. In low dosage when the system has good dispersion and fluidity; when the dosage is greater than 0.3%, the fluidity has a very obvious growth, pay attention to control the accuracy of the dosage.

packaging and storage
