The waterproofing principle and characteristics of polymer modified cement waterproof mortar

Polymer-modified-cement waterproof mortar, a kind of high-performance waterproof material, is carefully formulated by mixing fine cement, aggregates, redispersible polymer powder, and other specialized additives. The core waterproofing principle of Polymer-modified-cement waterproof mortar lies in the perfect combination of redispersible polymer powder and the cement matrix. During the hardening process of cement, the redispersible polymer powder forms a continuous and tight network structure, which acts as an indestructible barrier, effectively preventing the intrusion of external water molecules.

Does tile adhesive contain formaldehyde?

Just hearing the name "tile adhesive", many people may think it's just cement mixed with glue. In fact, tile adhesive is not glue. It is formulated from high-quality cement, sand, redispersible emulsion powder, and various polymers. It is a safe and environmentally friendly product, containing no harmful substances such as formaldehyde or benzene.

Application of redispersible polymer powder in putty

In the external insulation system for exterior walls, the application of the putty layer must follow the "flexible transition" principle: the flexibility (deformation resistance) of the putty layer must be higher than that of the underlying plaster mortar base, while being lower than that of the decorative coating layer on its surface. This ensures that each layer of material can gradually release and absorb stress, preventing cracking due to incoordination of deformations. Therefore, putty used in insulation systems often requires the addition of a sufficient amount of redispersible polymer powder to ensure adequate flexibility.

The important role of redispersible emulsion powder in self-leveling

By incorporating 2% to 3% of redispersible emulsion powder, the wear resistance of self-leveling mortar can be significantly improved. The redispersible polymer powder disperses and forms a film within the mortar paste, filling the pores of the paste and interlocking with the hydration products of cement to form a three-dimensional network structure, thereby making the mortar structure denser.

Three major impacts of redispersible polymer powder on tile adhesive

In the production of tile adhesive, redispersible polymer powder (RDP) plays a crucial role. It does not only significantly enhances the performance of tile adhesive but also effectively addresses common issues during construction, such as tile detachment, hollowing, and cracking.

Employee Birthday Party Successfully Held at Hualian Top Technology

To convey corporate care and enhance team cohesion, Baoding Hualian Top Technology Co., Ltd. recently held a warm and heartfelt employee birthday party themed "Warmth in the Workplace, Together Towards the Future". More than 80 birthday employees gathered with company leaders and colleagues to celebrate their memorable birthdays.

The Characteristics of Insulating Mortar

The insulating system made from inorganic materials is composed entirely of pure inorganic substances. It is resistant to acids and bases, corrosion, does not crack or peel, and has high stability, eliminating aging issues, thus lasting as long as the building walls.

Waterproof mortar in dry mixed mortar

Waterproof mortar refers to a rigid waterproof material that achieves waterproofing and impermeability by improving the compactness and crack resistance of mortar. Mainly used for waterproofing projects that will not cause harmful cracks due to structural settlement, temperature, humidity changes, and vibration. There are three types of waterproof mortar used as waterproof layers in waterproofing projects: (1) rigid multi-layer plastering cement mortar; (2) Waterproof mortar mixed with waterproofing agent; (3) Polymer cement waterproof mortar:
