The applications of industrial-grade calcium oxide in rubber, plastics, and as a lubricant each possess unique characteristics. Below is a detailed analysis of these three aspects:
1. Application of Industrial-Grade Calcium Oxide in Rubber
Rubber, which primarily includes natural and synthetic types, boasts resistance to combustion, chemical corrosion, as well as excellent elasticity, abrasion resistance, and elongation properties. It has wide applications across various industries. As a widely used inorganic physical and functional filler, calcium oxide primarily serves as a physical filler in rubber production processes, with the following functions:
Enhances the physical properties of rubber products, such as strength, rigidity, dimensional stability, thermal stability, and chemical stability.
Acts as a drying and defoaming agent due to its strong water absorption capacity, which helps absorb moisture, eliminate bubbles, and reduce porosity in finished products.
High purity levels, with effective calcium content exceeding 90%, outperform market equivalents. Low impurity content and high purity make it suitable for light-colored or rubber products.
Exhibits excellent dispersion, allowing for blending with rubber in any proportion without affecting the incorporation of other additives, facilitating easier molding of compounded rubber.
Significantly increases product volume, effectively reducing the usage of natural rubber raw materials and lowering production costs.
2. Application of Industrial-Grade Calcium Oxide in Plastics
In the plastics industry, industrial-grade calcium oxide is commonly used as a filler and defoaming agent, featuring the following characteristics:
Effectively enhances the strength and stability of plastic products.
Possesses good dispersion properties, enabling easy and uniform mixing with plastics.
Functions as a defoaming agent, eliminating bubbles during plastic production and improving product quality.
3. Analysis of Industrial-Grade Calcium Oxide as a Lubricant
Calcium oxide itself does not possess the typical characteristics of lubricants, such as reducing friction coefficient and wear rate, and is therefore generally not recommended for use as a lubricant. However, under specific conditions, it may be used as part of a lubricant system or in combination with other lubricants. Yet, such cases are relatively rare and require specific conditions and formulations. The reasons include:
Calcium oxide readily absorbs moisture and carbon dioxide from the air, which may degrade lubricant system performance or cause failure.
Its high hardness may exacerbate friction and wear.
Mixing calcium oxide with other lubricant components may produce adverse reactions, affecting lubrication effectiveness.
