输送带为什么用 TPU
输送带用 TPU 的理由:耐磨好、耐油好、承载稳、寿命长——四条合起来,适合输送带。
耐磨是核心:物料摩擦。耐磨测试写进验收——磨穿,就是问题。
耐油不能省:接触油污。耐油测试写进验收——溶胀,就是问题。
承载摩擦油污,三道关
承载工况:物料承载。承载数据要验——拉断,就是问题。
摩擦工况:运转摩擦。耐磨数据要验——磨穿,就是问题。
油污工况:接触油污。耐油数据要验——溶胀,就是问题。

The conveyor belt wears through and runs off track after just two months, and halting the line for a day costs tens of thousands. If the conveyor belt's wear and oil resistance is not chosen correctly, moving materials just becomes burning money.
After running for two months, the runners wore out and went off track, stopping the production costs tens of thousands.
The conveyor belt is a 'component that bears abrasion': abrasion-resistant, oil-resistant, load-bearing. The material must be abrasion-resistant, oil-resistant, and stable in load-bearing — conclusion first: TPU is the mainstream for conveyor belts; for high-temperature conveying, a composite structure should be retained.
The biggest pitfall of conveyor belts: When testing materials for the first time, start with 200kg. Before mass production, test 200kg first — small batch testing of materials is the insurance for the conveyor belt.
The conveyor belt is a functional component: wear-throughs and breakages are both problems. Only by choosing the right material can the production line run smoothly — for functional components, don't skimp on material costs.
Why is TPU used for conveyor belts?
Reasons to use TPU for conveyor belts: good wear resistance, good oil resistance, stable load-bearing, long service life—combined, these four make it suitable for conveyor belts.
Wear resistance is key: material friction. Wear resistance testing is written into acceptance—wearing through is the problem.
Oil resistance cannot be compromised: it comes into contact with oil stains. Make sure to include oil resistance testing in the acceptance inspection—swelling indicates a problem.
Bearing friction and grease, three barriers
Load condition: material carrying. Load data needs to be tested — breaking, that is, the problem.
Friction condition: operating friction. Wear resistance data must be tested—if it wears through, it's a problem.
Oily condition: Contact with oil. Oil resistance data needs to be tested—swelling is the problem.
TPU or rubber? Conveyor belt at a glance
| Dimension | TPU | Rubber |
|---|
| Wear-resistant | Strong | middle |
| Oil-resistant | Good | Visual glue type |
| Bear; carry; support | Good | Good |
| Cost | Medium-high | Medium-high |
| Efficiency | extrude | Vulcanization |
| Purpose | mainstream | Special |
Table reading: TPU is wear-resistant and oil-resistant; rubber is good for special conditions—for conveyor belts, TPU is mainstream.
Choose according to working conditions: special rubber, conventional TPU.
Conveyor belt acceptance: first test with a small batch of 200kg
| Project | Quantity | Check |
|---|
| first attempt | 200 kg | Performance |
| Retest | Batch | Stable |
| Trial Production | small batch | Craft |
| Increase in volume | bulk goods | Contrast |
Form reading: Start small step by step, large batches will only be stable—first run 200kg for extrusion and wear resistance, and only increase to large batches once it passes.
Small batch trial material is the insurance for the conveyor belt.
Go straight to mass production, three pitfalls
Pitfall 1: Going straight to mass production. Jumping straight into mass production can lead to the entire batch being scrapped if it isn't wear-resistant — always test with a small batch first.
Pitfall 2: Oil resistance leakage test. Swelling — oil resistance test, must be tested.
Pitfall 3: Overstated wear resistance. Wear through — wear resistance should be measured and accepted based on actual tests.
Select conveyor belt material and start with a small batch test
Three questions: How much for the initial test, what standard for wear resistance, what medium for oil resistance. One verification: actual operation measurement — three questions and one verification make the supplier's details clear.
Small batch verification must be done first: 200kg of test material should be fully tested for wear resistance and extrusion stability. Test with a small batch first, then discuss large-scale production — small batch testing is the insurance for the conveyor belt.
Making sample retention a habit: retain samples for each batch, and retest for wear and oil resistance batch by batch. When changing materials between batches, compare first before increasing the volume—stable batches result in fewer customer complaints.
Conveyor belt: Clear mines according to this chart
| Phenomenon | Reason | Countermeasure |
|---|
| wear through | Insufficient wear resistance | Replace wear-resistant material |
| Swelling | Insufficient oil resistance | Replace with oil-resistant material |
| tear off | Insufficient load-bearing | Add enhancement layer |
| slip | Insufficient friction | Replace with high-friction material |
| Batch Drift | Formula fluctuation | Lock window |
Mainstream conveyor belt TPU, Shore A 85-95, abrasion resistance measured batch by batch according to wear. TPU's wear and oil resistance is its specialty; too soft and it collapses under load, too hard and it damages materials — A90 is the typical range for volume.
TPU is wear-resistant, oil-resistant, and efficient, while rubber belts have good anti-slip properties but are heavy and require vulcanization. For food conveying, look at food-grade TPE; for heavy-duty wear resistance, look at TPU—choose according to the material and the floor.
The conveyor belt wearing through is not because the material is not wear-resistant, but because the joint method and tension were not designed properly. Heat joints, cold joints, and mechanical joints have different strengths, and misaligned tension causes faster wear — first check the joint strength.
For the first trial batch, start with 200kg, enough for verification without overstocking. Run through the three checks of wear resistance, oil resistance, and joint strength before talking about mass production — going straight to full-scale production is gambling with the production line.
Small batch trial materials lock in the dimensions and wear resistance, and the customer placed follow-up orders for three consecutive batches. Each batch keeps samples to test wear and dimensions, and when changing systems, first do a small batch trial production before ramping up volume.
The strength of conveyor belt joints is graded according to hot splicing, cold splicing, and mechanical splicing, and tension deviation causes faster wear. TPU is highly efficient in wear and oil resistance. For heavy-duty wear resistance, look at TPU; for food conveyor belts, consider food-grade TPE. Check the joints first before discussing wear.
For the first trial material, start with 200 kg, and only increase the quantity after successfully passing the three wear-resistant and oil-resistant joint tests. Measure ground friction according to actual working conditions, record tension design in the acceptance, and for each batch, keep samples to measure wear and dimensions.
Joint strength is classified by method, and tension design is included in the acceptance test. Each batch of samples is retained to measure wear and dimensions; the first 200 kg sample passes three tests before ramping up, and ground friction is verified based on actual measurements.
First check the strength of the conveyor belt joints, then talk about wear. Heavy-duty TPU food-grade TPE is selected according to the material and ground, the strength of hot-welded, cold-welded, and mechanical joints differs. For the first trial material, 200 kilograms ran through the three tests successfully.
Each batch retains samples for wear and dimension.
For each batch of conveyor belts, samples are taken to measure wear and dimensions. For the first trial material, 200 kilograms are tested through three checkpoints. The joint strength is checked for tension before discussing wear. Going straight to full-scale production would be gambling with the production line, and ground friction is measured as actual.
Cologne customer case: shrinkage rate unstable, size fluctuates, switch system and continue three more orders
An industrial equipment factory in Zhongshan is experiencing unstable contraction rates in conveyor belts, with large size fluctuations. With Cologne's assistance in changing the system and switching grades (from SEBS-based to TPV-based), the dimensions became stable, and the customer placed follow-up orders for three consecutive batches. By changing the system, the size issue is addressed from the source—the contraction rate problem should first look at system stability.
Summary
For conveyor belt selection, try a small batch first, then test for wear resistance. For the first trial material, start with 200kg; small batch testing is a precaution.
