Automatic Dual‑Head Rotary Abrasion Tester QPI‑DP2800 - Application:

O profissional Automatic Dual Head Rotary Abrasion Tester QPI‑DP2800 is engineered for high‑precision evaluation of surface durability, wear resistance, and coating integrity using standardized rotary abrasion procedures. The instrument performs controlled abrasion through two independently driven rotary heads, enabling simultaneous testing of identical or different specimens under identical load and speed conditions. This dual‑head configuration increases repeatability, reduces operator influence, and supports advanced comparative testing.

ASTM Test Method Description (Taber Abrasion – ASTM D4060 / ASTM D1044 / ASTM D3884)

ASTM rotary abrasion standards quantify the resistência ao desgaste of coatings, plastics, laminates, flooring materials, and industrial surfaces by measuring material loss after a defined number of abrasion cycles. The method simulates long‑term mechanical wear through controlled rotational friction.

Core ASTM Procedure Using QPI‑DP2800

1. Specimen Preparation

   • The test specimen is cut to the required ASTM dimensions.

   • The surface is cleaned and conditioned to remove dust, oils, or contaminants.

   • The specimen is mounted securely on the abrasion platform using the precision clamping system.

2. Wheel Selection

   • Abrasive wheels are selected according to the ASTM material category (e.g., CS‑10, CS‑17, H‑18, H‑22).

   • The QPI‑DP2800 supports rapid wheel exchange and dual‑head parallel testing.

3. Load Configuration

   • Standard ASTM loads (typically 250 g, 500 g, or 1000 g per wheel) are applied using calibrated weight assemblies.

   • The dual‑head system ensures identical loading on both test stations.

4. Rotational Abrasion Cycle

   • The test begins with the programmed number of cycles (e.g., 100, 500, 1000 cycles).

   • The specimen rotates beneath the abrasive wheels at a controlled speed defined by the ASTM method.

   • The wheels create a uniform wear path through continuous contact and friction.

5. Material Loss Measurement

   • After the cycle count is completed, the specimen is removed and cleaned.

   • Wear is quantified by:

     • Mass loss (mg)

     • Wear index

     • Visual surface degradation

   • The QPI‑DP2800’s dual‑head design allows direct comparison between two materials or two coatings under identical conditions.

ASTM Output

The ASTM method provides:

• Wear Index (WI)

• Mass loss per cycle

• Visual wear classification

• Comparative durability ranking

These results support quality control, R&D, and material certification.

ISO Test Method Description (ISO 5470‑1 – Rotary Abrasion)

ISO 5470‑1 defines a standardized procedure for evaluating the abrasion resistance of flexible and rigid materials using a rotary abrasion system. The method ensures global comparability of wear performance across coatings, polymers, textiles, and industrial surfaces.

Core ISO Procedure Using QPI‑DP2800

1. Condicionamento de espécimes

   • The specimen is conditioned under ISO‑specified temperature and humidity.

   • The QPI‑DP2800’s stable platform ensures uniform specimen alignment.

2. Abrasive Wheel Selection

   • ISO wheels (e.g., CS‑10, CS‑17, H‑18) are installed according to material type.

   • Dual‑head operation allows simultaneous ISO testing of two specimens.

3. Applied Load

   • ISO loads are applied using calibrated weight assemblies.

   • The instrument ensures precise vertical force distribution on both heads.

4. Abrasion Cycle Execution

   • The specimen rotates beneath the wheels at the ISO‑defined speed.

   • The abrasion heads apply continuous friction, producing a standardized wear track.

   • The QPI‑DP2800’s automatic cycle control ensures exact compliance with ISO cycle counts.

5. Wear Evaluation

   • After testing, the specimen is cleaned and evaluated.

   • ISO wear performance is determined by:

     • Mass loss

     • Thickness reduction

     • Surface appearance changes

     • ISO wear index calculations

ISO Output

ISO 5470‑1 provides:

• Mass loss (mg)

• Wear index

• Surface degradation classification

• Internationally comparable abrasion performance data

Why Engineers Prefer the QPI‑DP2800 for ASTM & ISO Abrasion Testing

• Dual‑head parallel testing for high throughput

• Precision speed control for strict ASTM/ISO compliance

• Rapid wheel exchange system

• Stable specimen platform for repeatable results

• Automatic cycle counting and programmable test sequences

• Ideal for coatings, plastics, flooring, automotive materials, aerospace surfaces, and industrial laminates
