SUERC GY-TBY-60 Wash Sieve Residue Analyzer

Overview

The SUERC GY-TBY-60 Wash Sieve Residue Analyzer is a precision-engineered laboratory instrument designed for quantitative determination of sieve residue in carbon black, precipitated silica (white carbon black), and other fine particulate industrial powders. It operates on the principle of controlled-pressure water washing followed by mechanical sieving—fully compliant with ASTM D1514–80, the standard test method for sieve residue of carbon black. Unlike conventional gravity-fed or manual wash-sieve systems, the GY-TBY-60 integrates a self-regulating hydraulic pressure system, stainless-steel filtration architecture, and modular interchangeable sieve plates to deliver repeatable, operator-independent residue quantification. Its compact footprint (25% the volume of legacy ASTM D1514-compliant units) enables seamless integration into QC laboratories with space constraints, while its factory-calibrated assembly ensures immediate operational readiness upon power and water connection.

Key Features

• Self-contained, pre-assembled unit shipped fully calibrated—requires only AC power (220 V, 50 Hz) and potable water supply for immediate use.
• High-stability pressure regulation via spring-loaded direct-acting pressure controller (±0.05 MPa accuracy across 0.1–0.5 MPa range), eliminating external air compressors or pneumatic controllers.
• Triple-stage stainless-steel water filtration system: coarse (≥500 µm), medium (≥150 µm), and fine (≥45 µm) stages, each equipped with dedicated drain ports for sediment removal—minimizing filter clogging and extending maintenance intervals.
• Internally mounted vortex-type spray nozzle ensures uniform radial water distribution across the sieve surface without flow obstruction or sample displacement.
• Modular dual-configuration sieve plate holder accepts standardized 35 mesh (500 µm), 100 mesh (150 µm), and 325 mesh (45 µm) stainless-steel woven wire meshes; reinforced frame design prevents mesh deformation during high-pressure washing cycles.
• Robust construction: all wetted components fabricated from corrosion-resistant 304 stainless steel; housing meets IP54 ingress protection rating for laboratory environments.

Sample Compatibility & Compliance

The GY-TBY-60 is validated for routine analysis of carbon black (per ISO 4681, ASTM D3849, and GB/T 3778), precipitated silica (per ASTM D1799, ISO 10287), and other hydrophilic or dispersible inorganic powders used in rubber compounding, battery electrode slurries, and polymer masterbatches. It supports full traceability in GLP- and GMP-aligned quality control workflows. While the instrument itself does not generate electronic audit trails, its mechanical operation and standardized test protocol are compatible with laboratory documentation systems adhering to FDA 21 CFR Part 11 requirements when paired with controlled procedural SOPs and manual data recording. All sieve specifications conform to ISO 3310-1:2016 (test sieves—technical requirements and testing) and ASTM E11–22 (standard specification for wire cloth and sieves).

Software & Data Management

The GY-TBY-60 is a hardware-only, analog-operated instrument with no embedded firmware or digital interface. This design prioritizes long-term reliability, electromagnetic immunity, and regulatory simplicity—particularly advantageous in Class I Div 2 hazardous locations common in rubber manufacturing facilities. Test results are recorded manually per defined SOPs (e.g., weight of retained residue before/after drying, calculated as % w/w). Users integrate output into LIMS or ELN platforms via standardized template entry. Optional calibration certificates (traceable to NIM, China) and metrological verification reports are available upon request to support ISO/IEC 17025 accreditation requirements.

Applications

• Quantitative assessment of coarse particle contamination in carbon black grades (N110 to N990 series) prior to rubber mixing.
• Determination of oversize agglomerates in precipitated silica used in green tire tread compounds.
• Batch release testing of pigment dispersions, catalyst supports, and fumed silica in silicone elastomer formulations.
• Process validation of micronization and jet-milling efficiency in fine chemical production lines.
• Root-cause analysis of extruder die buildup or calendering defects linked to undispersed filler fractions.

FAQ

Is the GY-TBY-60 certified to ASTM D1514–80?
Yes—the instrument’s pressure delivery profile, spray geometry, and sieve retention methodology were specifically engineered to replicate and improve upon the functional requirements outlined in ASTM D1514–80, including specified flow rates and pressure stability thresholds.
Can custom mesh sizes be installed?
Yes—while standard configurations include 35, 100, and 325 mesh plates, the holder accommodates any ISO 3310-1–compliant woven wire sieve up to 200 mm diameter and 1.0 mm thickness.
What maintenance is required?
Routine tasks include periodic cleaning of drain ports, visual inspection of spray nozzle orifice integrity, and replacement of filter cartridges every 200 operational hours or per water quality logs.
Does it support automated data export?
No—it is a manually operated, non-digital instrument. Data capture follows paper-based or LIMS-integrated manual entry protocols aligned with laboratory quality management systems.
Is CE or UKCA marking available?
As a non-electronically controlled, low-voltage (<50 V SELV) mechanical analyzer, the GY-TBY-60 falls outside the scope of EU Machinery Directive 2006/42/EC and thus does not require CE marking; however, it complies with EN 61000-6-2/6-3 for EMC immunity and emission limits where applicable.
