Specification & Application (for Alumina Powder Transportation)
Product Overview
Wagon Liner is a professional flexible packaging product specially designed for the transportation of alumina powder by train. Adopting high-quality woven PE fabric processed by heat welding technology, it integrates wear resistance, tear resistance, dust proof, moisture proof and leak proof performance, effectively preventing alumina powder from leaking, absorbing moisture, caking and being polluted during long-distance train transportation. It is widely used in the non-ferrous metal industry, alumina production and transportation fields, providing a safe, efficient and cost-effective packaging solution for bulk alumina powder logistics, reducing transportation loss and ensuring product purity.
Product Specifications
| Parameter | Detailed Specification |
| Product Name | Wagon Liner (for Alumina Powder) |
| Material | High-strength woven PE fabric, processed by heat welding technology (no stitching, seamless connection to prevent powder leakage) |
| Material Thickness & Weight | Woven PE fabric: 150-200gsm; Total thickness: 0.3-0.5mm; Unit |
| Tensile Strength | Warp: ≥ 2000N/5cm; Weft: ≥ 1800N/5cm (resistant to pressure of bulk alumina powder and train vibration) |
| Elongation at Break | Warp: ≤ 15%; Weft: ≤ 18% (flexible, not easy to tear during loading, unloading and transportation) |
| Moisture & Dust Proof | Waterproof rate ≥ 99.5%, dust proof rate 100%; effectively isolating moisture, rainwater and dust, preventing alumina powder from caking and pollution |
| Leak Proof Performance | Seamless heat welding, no pinholes or gaps; can withstand static pressure of 5-8 tons/m² without leakage |
| Load Capacity | 20-60 tons per wagon (customizable according to train wagon size and alumina powder density) |
| Available Sizes | Customized for standard railway wagons (gondola wagon, covered wagon); length: 8-14m, width: 2.8-3.2m, height: 1.8-2.5m |
| Color | White, gray (standard, dirt-resistant); black, blue (customizable with minimum order quantity) |
| Accessories | Reinforced edges (heat-welded reinforcement, prevent tearing); fixing ropes (8-12 pcs, high-strength PE rope, load-bearing ≥ 5 tons each); anti-slip bottom (prevent liner displacement during train operation) |
| Certifications | ISO9001, REACH, RoHS (environmental compliance); non-toxic, odorless, no pollution to alumina powder |
Product Features
- Seamless Leak Proof: Adopting professional heat welding technology, the liner is seamless without stitching, eliminating pinholes and gaps that may cause alumina powder leakage, ensuring 100% leak proof during transportation.
- High Strength & Wear Resistant: High-strength woven PE fabric has excellent tensile, tear and wear resistance, which can bear the pressure of bulk alumina powder (up to 60 tons per wagon) and resist friction with the wagon inner wall during train operation.
- Moisture & Dust Proof: The dense woven PE structure forms an effective barrier against moisture, rainwater and dust, preventing alumina powder from absorbing moisture, caking, deteriorating or being polluted, ensuring the purity and quality of the powder.
- Anti-Slip & Stable: The anti-slip bottom design increases the friction between the liner and the wagon bottom, preventing the liner and alumina powder from shifting due to train vibration, braking or turning, avoiding local pressure concentration and liner damage.
- Easy Installation & Unloading: Lightweight design, easy to unfold and lay in the train wagon; equipped with high-strength fixing ropes for quick and firm fixation; the smooth inner surface facilitates rapid unloading of alumina powder without residue.
- Customizable & Durable: Supports customization of size, thickness, color and accessories (such as anti-UV treatment, reinforced load-bearing design) to adapt to different types of train wagons and transportation environments; reusable for many times, reducing packaging costs.
Product Application
Main Application Fields & Goods
- Non-Ferrous Metal Industry: Specialized for the transportation of alumina powder by train, including raw alumina powder, calcined alumina powder and other types of alumina products, suitable for large-volume bulk transportation.
- Alumina Production Enterprises: Transportation of alumina powder from production bases to smelting factories, railway stations or ports, adapting to long-distance and short-distance train logistics.
- Logistics & Transportation Industry: Used for railway bulk transportation of alumina powder, compatible with various standard train wagons (gondola wagon, covered wagon), reducing transportation loss and improving logistics efficiency.
Application Scenarios
Suitable for standard railway wagons (gondola wagon, covered wagon) in long-distance and short-distance train transportation; widely used in domestic railway logistics, industrial raw material transportation and other scenarios. It is an essential packaging product for alumina powder railway transportation, especially for large-volume, long-distance transportation that requires strict leak proof and moisture proof.
