Product Overview

The KR‑849 xenon‑arc light‑fastness weathering test chamber is comprehensive accelerated‑ageing laboratory apparatus. It reproduces natural outdoor environmental stresses including full‑spectrum sunlight irradiation, temperature fluctuation, humidity variation and simulated rain‑spray cycles. It evaluates light‑resistance, weather‑induced colour‑fading and photo‑ageing performance for dyed textiles, garments, geotextiles, leather, polymer plastics and other coloured substrates.
The long‑arc xenon lamp paired with specialised optical filters delivers daylight‑matching spectral distribution. Closed‑loop regulation manages irradiance, black‑panel‑temperature, chamber‑temperature and relative humidity throughout test cycles. Operators configure custom‑test sequences to complete light‑fastness and artificial‑weathering assessment efficiently, cutting down lengthy natural‑exposure periods. This instrument complies with GB/T 8427, ISO 105‑B02, GB/T 8430, ISO 105‑B04 and related global textile‑testing norms, widely used in dye‑finishing plants, apparel‑manufacturers, material‑R&D centres and accredited third‑party testing‑laboratories.

Core Product Competitive Advantages

  1. Multilingual Touch‑Screen HMI plus Industrial‑Grade PLC Control System
    Large‑size colour touch‑panel supports Chinese‑English bilingual operation. Dynamic real‑time icons visualise chamber running‑status. Equipped with Omron PLC main‑controller for powerful anti‑interference capability, adapting to long‑duration continuous‑lab‑operation scenarios.
  2. Low‑Energy‑Consumption Optimised Hardware Layout
    Energy‑saving circuit design keeps hourly power‑draw under 2.5 kWh. No extra high‑power voltage stabiliser is required for normal equipment deployment, lowering facility‑transformation cost for end‑user laboratories.
  3. Self‑Positioning Rotary Specimen‑Frame Assembly
    Clutch‑type transmission connects drive‑motor and rotating sample‑rack. The sample drum can rotate freely without motor‑driven force, making specimen mounting and removal highly convenient. Special structural design guarantees uniform light‑irradiance across every test‑sample position.
  4. Imported Ultrasonic Atomisation Humidification & Spraying Unit
    Premium ultrasonic atomising module generates fine homogeneous mist droplets with low‑noise output. It precisely fulfils humidity‑control and simulated‑rain‑spray requirements for artificial‑climate weathering‑test workflows.
  5. Dual‑Channel Redundant Electronic‑Circuit & Intelligent Self‑Diagnosis
    Redundant dual‑circuit hardware architecture enhances reliability for non‑stop long‑time‑running. Built‑in multi‑point status‑monitoring system achieves fault‑alert and self‑diagnosis functions, pointing out abnormal components to simplify maintenance work.
  6. Custom‑User‑Programmable Test‑Procedure
    Users can edit and store independent test‑profiles according to diverse‑standard‑requirements. Multiple parameter‑groups of illumination‑duration, humidity, temperature and spray‑cycle can be combined to satisfy different light‑fastness and weather‑ageing evaluation‑conditions.

Standard Complete Test Operating Workflow

  1. Pre‑Test Preparation
    Place unit on well‑ventilated horizontal lab‑location. Complete water‑supply, exhaust‑pipe and power‑supply connection. Check xenon‑lamp status, filter assembly, ultrasonic‑atomizer water‑tank and specimen‑clamps. Prepare textile or material test‑specimens together with blue‑wool reference‑standards. Call‑up or edit target test‑program via touch‑screen according to required‑testing‑standard.
  2. Specimen Installation
    Open test‑chamber door. Rotate specimen‑drum manually via clutch‑free‑rotation function. Secure samples and corresponding blue‑wool reference‑cards into standard‑specimen holders; fit shielding‑mask covers (1/2, 1/3, 2/3) as‑required. Ensure each sample is fixed flat without wrinkles. Close and lock chamber door.
  3. Initiate Accelerated Light / Weathering‑Ageing Test
    Trigger test‑start command. Equipment runs preset sequence: xenon‑arc‑lamp illumination, rotary‑drum rotation, temperature‑humidity closed‑loop‑regulation, and intermittent spray‑cycle if weather‑mode is enabled. System continuously monitors black‑panel‑temperature, chamber‑climate and lamp‑irradiance, executing auto‑compensation adjustment.
  4. Intermittent Observation & Test Completion
    Pause program periodically for intermediate‑colour‑change observation without taking‑down samples. Once pre‑set exposure‑time / radiation‑energy threshold is reached, the instrument terminates test‑run automatically. Open chamber door and retrieve specimens and blue‑wool‑standards.
  5. Result Evaluation & Post‑Test Maintenance
    Assess colour‑change grade of test‑samples against blue‑wool‑reference‑cards, record light‑fastness rating for lab‑report filing. Empty atomiser water‑tank, clean chamber interior residues. Shut‑down main‑power. Periodically inspect xenon‑lamp ageing‑condition, optical‑filter transparency and replace consumables on schedule.
