{"product_id":"hydrophilic-lightweight-calcium-carbonate","title":"Hydrophilic Lightweight Calcium Carbonate","description":"\u003cp\u003eProduct Name Name: Hydrophilic Lightweight Calcium Carbonate Product Overview Nano calcium carbonate is a novel lightweight calcium carbonate product. Due to the ultra-fine grinding of calcium carbonate particles—characterized by fine and uniform particle size, narrow size distribution, large specific surface area, excellent surface activity and dispersibility, as well as high surface energy—this material exhibits superior properties that conventional calcium carbonate materials lack, enabling a wider range of applications. The primary synthesis methods for nano calcium carbonate include the carbonation method and the precipitation method; the resulting calcium carbonate typically exists in the form of calcite, with particle sizes ranging from tens to hundreds of nanometers. In polymer melts, the agglomeration of filler particles can adversely affect the performance of the composite material; therefore, surface modification of the nano calcium carbonate must be performed prior to filling. Commonly used surfactants include silane coupling agents, stearic acid, and aluminate\/titanate coupling agents; these coupling agents typically contain both hydrophilic and hydrophobic groups, which, upon binding with the functional groups on the calcium carbonate surface, can reduce the surface energy of the nano calcium carbonate particles and improve their dispersibility(This product is unmodified.). Technical Parameter 名称 Product name 轻质碳酸钙 Lightweight calcium carbonate 粒径 Diameter 0.2-1um(SEM) 纯度 Purity 99wt%(EDS) 外观 Appearance 白色粉末white powder PH值 PH 9.0-11.0(10%浓度)10% concentration Product Features It has a low water content, is nearly neutral in pH, exhibits excellent chemical stability, and does not undergo any chemical reactions with curing agents or other components present in the adhesive. The high addition amount can significantly reduce the cost of adhesive products (e.g., the usage in silicone rubber sealing gaskets is 50% or more, while the usage in polyurethane adhesives is 20–30%). It serves as a reinforcement agent that can enhance the mechanical properties of the adhesive, reduce its shrinkage rate and thermal expansion coefficient during curing, increase its thermal conductivity, improve its heat resistance and adhesion, and elevate its mechanical strength (hardness and compressive strength) as well as its corrosion resistance; furthermore, it provides lubricating effects for the adhesive, optimizes the processing conditions, and leads to a comprehensive improvement in the bonding performance. Nano-calcium carbonate features a small particle size and a large specific surface area; after undergoing appropriate surface treatment, it exhibits excellent phase compatibility with adhesives. Within adhesive systems, it can serve as a thixotropic agent to regulate the viscosity of the adhesive, prevent sagging during application on vertical surfaces, and enhance its retention properties. During the production of colorants, nano-calcium carbonate readily absorbs color but does not affect the color of the final product. Different adhesives exhibit distinct modification effects: in PVC plastic sols, it can improve their rheological properties; in silicone structural sealants, it can enhance their strength and wear resistance; in hot-melt adhesives, it can provide additional reinforcement and heat resistance; and in water-based adhesives, it can serve to thicken the adhesive and increase its viscosity. Application Fields Plastics Industry: As a filler and reinforcing agent, nano-calcium carbonate can enhance the rigidity, toughness, and heat resistance of plastic products, while also improving their processability. For example, adding a small amount of lightweight calcium carbonate to PVC products can increase their tensile strength. Rubber Industry: Nano-calcium carbonate is utilized in high-performance tires, automotive components, bicycle tires, and running shoes, where it can improve the strength, rigidity, and durability of these products. Papermaking Industry: When used as a filler, nano-calcium carbonate can enhance the brightness, whiteness, and smoothness of paper, making it suitable for premium packaging papers. Coatings and Inks: The addition of nano-calcium carbonate to coatings and inks can impart better gloss and durability to the coatings, while simultaneously reducing production costs. Pharmaceutical Industry: Nano-calcium carbonate serves as a key component in culture media and a calcium source additive, as well as being utilized in antibiotic production, analgesics, and gastric medications.
