Low viscosity hydroxypropyl methylcellulose for self-leveling mortar

Low-viscosity hydroxypropyl methylcellulose is an additive commonly used in making self-leveling mortars. It is a chemical substance extracted from natural plant cellulose and has excellent dispersion and thickening properties.

Hydroxypropyl methylcellulose is a white or light yellow powder with the following properties:

1. Thickening: HPMC can significantly increase the viscosity and yield stress of self-leveling mortar and improve its fluidity.
2. Water retention: HPMC can absorb and retain moisture, control the curing process of self-leveling mortar, and improve its strength and stability after curing.
3. Crack resistance: HPMC can enhance the toughness of self-leveling mortar and prevent cracks during use.

4. Environmental protection: HPMC is a natural cellulose, biodegradable and meets environmental protection requirements.

Application of hydroxypropyl methylcellulose in self-leveling mortar:

1. Fluidity: Adding HPMC can increase the viscosity of self-leveling mortar, giving it better fluidity during construction. At the same time, the water retention of HPMC can also prevent segregation of mortar during transportation and construction.
2. Curing time: HPMC can control the curing time of self-leveling mortar so that it can cure quickly under appropriate temperature and humidity conditions and improve construction efficiency.
3. Strength and stability: The reinforcing effect of HPMC can improve the strength and stability of self-leveling mortar, giving it better performance during load- bearing and use.
4. Durability: HPMC can enhance the durability of self-leveling mortar, giving it good anti-aging performance and weather resistance during

Dosage:

In practical applications, the addition amount of cellulose ether is usually 0.2-0.5% of the total amount of mortar. The specific addition amount should be determined according to the specific material ratio and usage requirements. At the same time, when using fiber cord ether, you also need to pay attention to factors such as compatibility with other additives and control of the construction process.
In short, cellulose ether is a commonly used self-leveling mortar additive that can improve the performance and construction effect of mortar. It has broad application prospects in the construction industry.
