Hydroxypropyl starch (HPS) is widely used in construction and is mainly used to improve the performance of various building materials.
Thickening agent: HPS has good thickening ability and can significantly increase the viscosity of building materials, making them easier to construct and form.
Water-retaining agent: HPS has good water-retaining properties and can prevent water from evaporating too quickly, ensuring that cement or gypsum-based materials have enough moisture to react during the hardening process, thereby improving the strength and durability of the material.
Improved constructability: HPS can improve the construction performance of building materials, making them easier to apply and scrape, reducing construction difficulty and time.
Anti-sag: HPS can improve the anti-sag of the material and prevent the material from sliding down during construction on vertical surfaces, thereby ensuring construction quality.
Adhesion: HPS can enhance the bonding force between building materials and substrates, improve material adhesion, and reduce the risk of falling off and cracking.
Crack resistance: By improving the water retention and adhesion of the material, HPS can effectively reduce the cracks that occur during the hardening process of the material.
Reduce shrinkage: HPS can control the evaporation rate of water in the material, reducing the risk of shrinkage and cracking, thereby improving the stability and durability of the material.
Extended opening time: HPS can extend the opening time of materials, giving construction workers more time to make adjustments and repairs, improving construction efficiency.
Versatility: HPS is suitable for a variety of building materials, including cement mortar, tile adhesive, putty powder, gypsum plaster, etc., and can play a role in different application scenarios.
Environmental protection: HPS is a non-toxic and odorless natural polymer material, which is environmentally friendly and meets the environmental protection requirements of modern building materials.
Through these characteristics, HPS plays an important modification role in building materials and can significantly improve the performance and construction effects of materials.
