The detection of diluents involves many different projects、 including the composition and quality of diluents、 particle size distribution、 surface charge、 dust hazard、 waterproofing、 and antioxidant capacity. The following are common diluent testing items: composition and quality analysis、 mainly involving the analysis of chemical composition、 content、 and pH value. Particle size distribution analysis、 including average particle size、 particle percentage、 particle shape、 etc. Surface charge analysis、 also known as wettability testing、 involves the interaction between particle surfaces and liquids. Dust hazard assessment、 including inhalation toxicity testing、 eye irritation、 skin irritation、 and mutagenicity. Waterproof evaluation、 considering the usage environment of the diluent、 mainly focuses on the stability of the diluent under wet conditions. The evaluation of antioxidant capacity mainly evaluates the quality of diluents by measuring their oxidation capacity. Detection range: oxide diluents (such as calcium oxide、 magnesium oxide、 etc.)、 silicate diluents (such as silicon dioxide、 micro powder quartz、 etc.)、 titanium dioxide、 carbonate diluents (such as barite、 calcite、 etc.)、 aluminate diluents (such as aluminum hydroxide、 aluminum carbonate、 etc.)、 aluminum silicate diluents (such as bentonite、 nano gelatin、 etc.)、 nanomaterial diluents (such as nano titanium dioxide、 nano alumina、 etc.)、 organic diluents (such as polymers、 animal glue、 resins、 etc.) Metal thinners (such as iron powder、 copper powder、 aluminum powder、 etc.)、 other inorganic thinners (such as zeolite、 sulfate、 sodium hydroxide、 etc.)、 etc. Related reference standards and specifications: AS/NZS 1580.208.1-1999 Test methods for paints and similar materials: Method 208.1: Diluent compatibility: AS/NZS 1580.214.4-1996 Test methods for paints and similar materials: Method 214.4: Durability rotary diluent ASTM D3524-2014 Test method for determining diesel fuel diluent in waste diesel engine oil by gas chromatography Purpose of obtaining a test report: 1. Evaluate the quality of the product; 2. Determine the product quality level、 i.e. the severity of defects; 3. Inspect the process flow and supervise the process quality; 4. Collect、 statistics、 and analyze quality data to lay the foundation for quality improvement and management activities; 5. Introduce arbitration inspection to determine the responsibility for quality accidents. The purpose of handling third-party testing reports is to obtain an independent、 objective、 and professional evaluation result to confirm whether the tested items or services comply with relevant regulatory standards、 quality requirements、 or technical specifications、 and to verify their safety、 reliability、 and performance. Third party testing reports are typically used in areas such as product certification、 market access、 supply chain management、 trade negotiations、 and dispute resolution. Precautions for Testing Report: Carefully read and understand each section after receiving the testing report. Ensure that there is a "research and testing special seal" and official seal in the report、 and check the anti-counterfeiting QR code to confirm its effectiveness. Confirmation information: Verify whether personal or organizational information is accurate and accurate. If the report is not stamped with the "Research and Testing Special Seal" or official seal、 it is invalid. Pay attention to the test results: Focus on the summary and detailed information of the test results. If in doubt、 consult relevant engineers and it is strictly prohibited to alter the report. Pay attention to the reference range: Check the reference range of the test results to see if the results are normal. As the reference range varies depending on factors such as samples、 test methods、 reference standards、 etc.、 please contact our engineers to discuss your specific situation. Objection handling: If you have any objections to the test report、 please file an appeal within 15 days of receiving the report. Late appeals will not be accepted.
