BRT-1000D Portable Carbon Black Content Tester

The BRT-1000D Portable Carbon Black Content Tester is an intelligent, high-precision laboratory testing system engineered strictly in accordance with ISO 6964, IEC 60811-4-1, GB/T 13021, and GB/T 2951.41 standards. Designed for polyolefin plastic pipe manufacturers, wire and cable quality inspection centers, and highway geosynthetic testing labs, it evaluates the precise carbon black, ash, and mineral filler percentages in polyolefin resins (PE, PP, PB), electrical insulation sheaths, and geotextiles.

Featuring a 7-inch LCD touchscreen interface, an integrated host-and-control frame, and a wide operating temperature range from room temperature up to 999.9 °C, this Carbon Black Content Tester automates the complete pyrolysis and calcination testing cycle. Equipped with automated N2 and O2 gas stream switching, nano-tape furnace thermal insulation, dual industry-dedicated combustion chambers, and an integrated mini thermal printer, the BRT-1000D delivers certified analytical consistency for quality control and material compliance verification.

Carbon Black Content Tester Compliance & Standards

This automated pyrolysis and calcination analyzer enables certified testing facilities to conduct standardized material composition evaluations across global testing frameworks:

Technological Features of BRT-1000D Carbon Black Content Tester

• Automated Gas Stream Switching (N2 to O2)

  Features internal solenoid valves controlled via software presets to automatically supply inert Nitrogen (N2) during the initial pyrolysis stage and switch to Oxygen (O2) for final sample calcination without manual valve toggling.

• PID Programmable Temperature Control (RT to 999.9 °C)

  Driven by a PID microcomputer controller that stores multiple ramp-and-hold temperature curves, delivering stable, uniform heat distribution inside the heating chamber.

• Advanced Nano-Tape Thermal Insulation Furnace

  Incorporates high-efficiency nano-insulation lining inside the tubular electric furnace, preventing external body heating, lowering power consumption, and maintaining tight thermal uniformity across the 300 mm heating zone.

• Dual Industry-Dedicated Combustion Chamber Options

  Offers specialized porcelain combustion boat and gas flow configurations tailored specifically to either the plastic pipeline industry or the wire and cable insulation industry.

• Automated Result Calculation & Mini Thermal Printer

  Automatically calculates Carbon Black %, Ash %, and Filler % upon entering initial and final specimen mass values on the 7-inch touchscreen, then prints instant test reports via the built-in thermal printer.

Testing Workflow & Target Applications

Standardized Testing Workflow:

1. Weigh a clean porcelain combustion boat and record the mass ($m_1$). Add approximately 1g of prepared polyolefin sample and record the total initial mass ($m_2$).
2. Insert the boat into the quartz tube of the tubular furnace, seal the chamber, and launch the programmed test sequence on the 7-inch touchscreen.
3. The instrument purges the furnace with Nitrogen (N2) gas and heats the specimen to cause thermal pyrolysis of the polymer matrix under inert conditions.
4. Upon completing thermal decomposition, the system automatically switches the gas supply to Oxygen (O2) for complete calcination of the remaining carbon black residue.
5. After cooling down, input the remaining masses into the controller; the system automatically calculates and prints the percentage of Carbon Black %, Ash %, and Mineral Filler %.

Target Customer Applications:

• Polyethylene (PE), polypropylene (PP), and polybutylene (PB) pipe and fitting manufacturers.
• Power cable, fiber optic cable, and electrical insulation sheath production lines.
• Highway engineering geosynthetics, geomembrane, and geotextile quality inspection centers.
• Third-party polymer testing laboratories and university material research institutes.

Carbon Black Content Tester FAQ

Q1: How does the automatic gas switching function operate on the BRT-1000D?

A: The system software regulates internal solenoid valves to purge the chamber with inert Nitrogen (N2) during the initial pyrolysis phase, then automatically switches to Oxygen (O2) for complete sample calcination based on preset time profiles.

Q2: What is the primary difference between the wire/cable and pipe testing configurations?

A: The two configurations differ in combustion boat volume dimensions and gas flow rate scale settings (3 L/min for wire & cable vs. 250 mL/min for pipe materials) to strictly comply with their respective standard protocols (IEC 60811-4-1 vs. ISO 6964).

Q3: Why is nano-tape insulation advantageous in a calcination furnace?

A: Nano-tape insulation provides superior thermal resistance compared to traditional ceramic fiber. It ensures that heat stays trapped within the 300 mm heating zone for tight temperature uniformity while keeping the external instrument chassis cool and safe to touch.
