Chlor-alkali industry, a vital sector in chemical manufacturing, operates in highly aggressive environments. Its core processes—such as brine electrolysis, chlorine gas production, and caustic soda synthesis—involve exposure to extreme conditions: strong acids (e.g., hydrochloric acid), corrosive gases (like chlorine), high-temperature brine, and other reactive media. Traditional lining materials, including metals and plastics, often degrade rapidly under such stress, leading to frequent equipment failures, costly downtime, and safety hazards. To address these challenges, the chemical processing industry increasingly relies on advanced, corrosion-resistant solutions—with ceramic balls emerging as a game-changer for lining critical equipment in chlor-alkali systems.

Superior Corrosion Resistance: The Core Advantage
The primary strength of ceramic balls as a corrosion-resistant lining lies in their exceptional chemical stability. Crafted from high-purity alumina or other engineered ceramics, these balls exhibit a dense, inert structure that resists attack from the full spectrum of chlor-alkali process fluids. Unlike metals, which corrode through oxidation or chemical reactions, ceramic materials form a passive oxide layer that acts as a barrier against brine, chlorine, and acidic byproducts. For instance, in chlor-alkali electrolysis cells, where brine (sodium chloride solution) circulates at high temperatures, ceramic balls prevent pitting, crevice corrosion, and stress corrosion cracking—common issues with carbon steel or rubber linings. This inherent resistance ensures the lining maintains its integrity even after years of operation, keeping equipment functional and safe.
Enhanced Equipment Longevity and Operational Efficiency
Beyond corrosion resistance, ceramic ball linings significantly extend the lifespan of chlor-alkali equipment. By acting as a physical barrier, they protect the underlying metal or composite materials from direct contact with corrosive media, reducing wear and tear. This translates to fewer repairs, less unplanned downtime, and lower maintenance costs—key factors in optimizing operational efficiency. Additionally, ceramic balls maintain their structural integrity under the high temperatures (up to 1200°C) and mechanical stresses encountered in chlor-alkali plants, ensuring consistent performance. For example, in chlorine gas compressors or acid storage tanks, a ceramic ball lining can reduce equipment replacement cycles from 3–5 years to 10+ years, allowing plants to redirect resources toward production rather than repairs.
Technical Specifications and Diverse Applications
Ceramic balls for chlor-alkali lining are engineered to meet specific industrial requirements. Key technical parameters include: material composition (typically 90%–99% alumina for maximum durability), size range (5–50mm to fit various equipment dimensions), and mechanical properties (high hardness, low porosity, and thermal shock resistance). They are available in both spherical and irregular shapes to ensure optimal packing and coverage, adapting to curved surfaces or tight spaces in reactors, heat exchangers, and pipeline systems. These versatile products find applications across the chlor-alkali value chain: from the anode compartments of electrolysis cells to the brine storage tanks in PVC production facilities. Their compatibility with diverse process conditions makes them a universal solution for corrosion protection in the industry.
