The rubber Ceramic Lining is not a single material. Instead, it's a wear-resistant lining material created through a special process by combining high-hardness Alumina ceramic with highly elastic natural rubber/nitrile rubber. Its core structure and performance can be summarized as a perfect combination of "hard protection + soft cushioning":

1. Core Structure: Three-layer composite, each performing its own function

Surface layer (wear-resistant layer): Made of 92%-95% pure alumina ceramic, it boasts a Mohs hardness of 9 (second only to diamond) and a compressive strength exceeding 1800 MPa. It directly withstands high-frequency impact and friction from materials, boasting wear resistance 20-30 times that of ordinary steel, serving as the lining's "first line of defense."

Intermediate layer (bonding layer): Utilizing a high-strength modified epoxy resin adhesive, the ceramic and rubber are tightly bonded, achieving a peel strength of ≥8 MPa. This ensures the ceramic retains its integrity under severe vibration and impact, preventing secondary wear caused by loosening of the ceramic. Bottom Layer (Buffer Layer): This elastic rubber layer, 3-10mm thick, not only absorbs the kinetic energy generated by material impact (reducing damage to the equipment base), but also conforms to minor surface irregularities, reduces installation gaps, and provides a certain degree of sealing and noise reduction.

2. Performance Advantages: Significant Advantages over Traditional Wear-Resistant Materials

Compared to pure ceramic liners (brittle and prone to breakage), wear-resistant steel plates (inadequate wear resistance and heavy weight), and cast stone liners (complex installation and poor impact resistance), rubber ceramic liners offer comprehensive performance that is more suitable for complex industrial working conditions.

2. Core Application Scenarios for Rubber Ceramic Liners: Where Wear Exists

With its dual properties of "wear resistance and impact resistance," rubber ceramic liners have become the "standard" for equipment protection in multiple industries, particularly suitable for critical areas with high material flow rates, coarse particles, and high impact:

1. Mining Industry: Resolving wear in slurry and ore transportation

Applications: Slurry pipes in flotation plants, ball mill outlet chutes, vibrating screen hoppers, and crusher discharge ports. Problem Solved: Mining slurry contains large amounts of hard particles such as quartz sand and iron ore. Conventional pipelines require replacement every 1-3 months. However, pipelines lined with Rubber Ceramic Linings can extend their service life to 3-5 years, reducing maintenance frequency by over 80% while also preventing environmental pollution caused by slurry leaks.

2. Power Industry: Fly Ash and Desulfurization Slurry Protection

Application Areas: Fly ash conveying pipelines in thermal power plants, slurry pipelines in desulfurization systems, the inner walls of electrostatic precipitator hoppers, and coal pulverizer drop pipes.

Problem Solved: Fly ash is highly hard (6-7 on the Mohs hardness scale). Long-term transportation can cause pipeline thinning or even perforation. Desulfurization slurry contains acidic substances, which can also cause corrosion. The rubber ceramic lining's wear-resistant ceramic layer and corrosion-resistant rubber layer protect against both damage, extending equipment life to 4-6 years. 3. Metallurgical Industry: Protection of High-Temperature Materials and Metal Slag

Applications: Blast furnace coal injection piping in steel mills, converter slag ditch linings, sintering machine mixture chutes, and coal conveying pipelines in coking plants.

Problem Solved: Materials in the metallurgical industry often contain high-temperature metal particles (e.g., steel slag temperatures exceeding 1000°C). Rubber ceramic linings can be made of high-temperature resistant rubber (temperature resistance -40°C to 200°C). The ceramic layer withstands high temperatures and does not deform, effectively resisting the impact of high-temperature materials, preventing premature failure of slag ditches and pipelines due to high-temperature wear and corrosion.

4. Chemical Industry: Wear-Resistant Protection for Corrosive Materials

Applications: Acid and alkaline material conveying pipelines in chemical plants, the inner walls of pellet silos in fertilizer plants, and phosphate slurry pipelines in phosphate chemical plants.

Problem Solved: Chemical materials are often corrosive, and traditional metal liners are easily corroded. However, the rubber layer (such as nitrile rubber) of rubber ceramic liners is acid and alkali resistant, and the ceramic layer is chemically stable, allowing long-term use in "corrosive and abrasive" conditions, reducing the risk of equipment leakage. III. Selection and Installation: These Three Key Details Determine the Effectiveness of Rubber Ceramic Lining

The effectiveness of rubber ceramic lining depends not only on product quality but also on selection criteria and installation techniques. Companies should pay close attention to the following details when purchasing:

1. Selection: Choose the right "ceramic + rubber" model based on the operating conditions.

Ceramic Selection: For high-wear, low-impact applications (such as fly ash pipelines), choose 95% high-alumina ceramic (optimal wear resistance). For high-impact, medium-wear applications (such as mine chutes), choose 92% high-alumina ceramic (slightly more tough and less prone to cracking). For lightweighting, choose silicon carbide ceramic (30% lighter than high-alumina ceramic, with comparable wear resistance).

Rubber Selection: For normal operating temperatures (0°C-80°C), choose natural rubber (excellent elasticity and low cost); for high-temperature applications (80°C-200°C), choose styrene-butadiene rubber (resistant to high-temperature aging); for corrosive applications (acidic and alkaline environments), choose nitrile rubber or fluororubber (chemical resistance). 2. Installation: Three key steps are essential.

Substrate preparation: The equipment substrate (such as the inner wall of a pipe) must be derusted and degreased. If the surface is uneven, use putty to level it. An unclean substrate will result in poor adhesion to the lining, making it prone to peeling later.

Bonding process: Use a specialized epoxy adhesive (must meet "heat resistance and aging resistance") and apply it evenly (3-5mm). Keep the gap between the linings ≤2mm to prevent material from seeping through the gap and corroding the substrate.

Curing: After bonding, cure at room temperature (20-25°C) for 24-48 hours. If the temperature drops below 10°C, extend the curing time or apply heating to ensure complete curing of the adhesive and avoid premature operation that could cause the lining to shift.

3. After-sales service: Focus on "warranty period + repair service."

High-quality Rubber Ceramic Lining Manufacturers offer a 1-3 year warranty (free replacement for non-intentional damage during the warranty period) and provide on-site installation guidance or on-site installation services. When purchasing, companies need to avoid "low-priced, low-quality" products - some small factories use low-purity ceramics (such as 85% high-aluminum ceramics) or recycled rubber, which have a wear resistance of only 1/3 of that of high-quality products, and are prone to problems such as ceramic shedding and rubber aging and cracking.
