GinShiCel® HPMC from Haishen New Materials Empowers Mortar Upgrading and Builds a Solid Foundation for High-performance Construction
As a core foundational material for construction projects, the workability and durability of mortar directly determine the quality and service life of buildings. Zhejiang Haishen New Materials Co., Ltd., a high-tech enterprise with over 30 years of expertise in the cellulose ether sector and a participant in formulating industry standards, has independently R&D and manufactured its proprietaryGinShiCel® Hydroxypropyl Methylcellulose Ether (HPMC). Boasting outstanding water retention, thickening and bonding-strengthening properties, this product serves as the "performance-core additive" in cement-based and gypsum-based plastering mortar, repair mortar and waterproof mortar. With precise formulations and scientific dosage, it provides critical support for improving quality and efficiency in construction projects worldwide.
Precisely Empowering Three Types of Mortar: Functional Application Scenarios of Haishen HPMC
Cement-based & Gypsum-based Plastering Mortar: Balancing Workability and Long-term Stability
In cement-based plastering mortar, its core functions are reflected in three key aspects:
- Powerful water retention and locking
It prevents the base layer from absorbing water too quickly or moisture from evaporating rapidly, ensures the full hydration of cement, fundamentally reduces dry cracks and strength loss, and is suitable for complex construction environments such as high-temperature and dry conditions.
- Optimized workability
It precisely adjusts the viscosity and thixotropy of mortar, improves the smoothness of plastering and anti-sagging performance, effectively avoids sagging and hollowing problems during vertical construction, lowers operation difficulty and enhances construction efficiency.
- Enhanced bonding strength
It strengthens the adhesion between mortar and the base layer through intermolecular forces, reducing the risk of peeling off in the later stage.
Targeting the characteristics of gypsum-based plastering mortar, such as rapid hydration rate and susceptibility to shrinkage cracking, HPMC further exerts its functions of retarding hydration, retaining water and enhancing crack resistance. On the one hand, it locks in the moisture required for gypsum hydration, extends the open time for construction, and reserves ample room for refined operations. On the other hand, it forms a uniform polymer network structure, inhibits shrinkage stress during gypsum hardening, significantly reduces the probability of cracking, and simultaneously improves the smoothness, wear resistance and durability of wall surfaces. It is widely suitable for interior wall, ceiling and other interior decoration and commercial decoration scenarios.
Repair Mortar: Enhancing Bonding Strength and Crack Resistance for Diverse Repair Requirements
Repair mortar needs to meet special requirements such as the integration of new and old base layers, crack repair, and rapid hardening. With its flexible performance regulation capability, HPMC has become a "performance stabilizer" for repair projects. Its core functions are concentrated in three aspects:
- Powerful water retention ensures the full hydration of cement, improves the anti-bleeding performance of mortar, and avoids structural looseness caused by moisture loss.
- Enhanced interfacial adhesion enables the new mortar to closely bond with the old base layer, fundamentally eliminating problems such as secondary cracking and peeling, and is suitable for regular repair scenarios of building walls and floors.
- Flexible adaptation to scenario requirements: For rapid repair or heavy-duty scenarios such as roads and bridges, the low-viscosity type of Haishen HPMC can ensure mortar fluidity while avoiding excessive thickening that affects hardening speed, achieving dual guarantees of repair efficiency and structural strength.
Waterproof Mortar: Building a Dense Barrier and Constructing a Long-lasting Waterproof Defense Line
The core requirements of waterproof mortar are impermeability and long-term durability. By optimizing the internal structure of mortar, HPMC builds a comprehensive waterproof barrier. High-viscosity HPMC models mainly perform three functions in waterproof mortar:
- Prolonging cement hydration time to improve the overall compactness of mortar, reduce porosity, and structurally enhance impermeability grade.
- Forming a closed polymer film to accurately fill the tiny pores inside the mortar, block water penetration paths, and provide long-lasting waterproof protection for key parts such as roofs and basements.
- Optimizing construction stability: relying on its thickening property, it prevents bleeding and segregation during mortar application, ensures uniform thickness of the waterproof layer, avoids local waterproof weak points, and further enhances waterproof reliability.
Functional Core: Three Core Values of Haishen HPMC
As a "multifunctional performance modifier" for mortar systems, the core values of Haishen GinShiCel® HPMC run through the entire construction process, forming a standardized empowerment logic.
- Core value: Water retention and locking
As the foundation for performance guarantee of all types of mortar, it ensures the full hydration of cementitious materials by stabilizing water supply, avoids dry cracking and insufficient strength, and is suitable for construction environments with varying temperatures and humidity levels.
2.Core value: Workability optimization
By regulating viscosity and thixotropy, it endows mortar with both smoothness and anti-sagging property, lowers the construction threshold, improves operation efficiency, enhances adhesion to the base layer, and reduces quality defects.
3.Core value: Structural stability enhancement
Through film-forming ability and network structure construction, it improves the comprehensive performance of mortar such as crack resistance, impermeability and wear resistance, extends the service life of buildings, and meets the development needs of green buildings and energy-saving projects.
