Uma Lime Quality Assurance and Laboratory
Ensuring Excellence in Every Batch
At Uma Lime, we are committed to delivering the highest quality lime products that meet stringent industry standards and exceed customer expectations. Our dedication to quality is reflected in our robust quality assurance processes and state-of-the-art laboratory facilities.
We maintain rigorous quality control standards by strictly following ASTM guidelines for testing our quicklime and limestone products. These standards, such as ASTM C25 and ASTM C110 for quicklime, limestone. Alongside XRF analysis, serve as crucial references in our testing protocols. By adhering to these standards, we ensure that our quicklime and limestone consistently meet industry-leading benchmarks, delivering dependable and top-quality materials for a wide range of applications to our valued customers.
Our Quality Assurance Process
1. Raw Material Analysis
Our commitment to quality begins with the careful selection and analysis of raw materials. We conduct thorough inspections to ensure that our limestone and other inputs meet the highest standards for production. We source our raw materials from trusted suppliers operating mines in Ras Al Khaimah and Fujairah, ensuring consistency and reliability in every batch.
2. In-Process Monitoring
Throughout the production process, we implement rigorous in-process monitoring. This includes regular sampling and testing to maintain product consistency and identify any deviations early, ensuring that each batch meets our high-quality standards.
3. Final Product Testing
Before our lime products reach you, they undergo comprehensive testing. We measure critical parameters such as calcium content, particle size, and purity to ensure they meet the precise specifications required for various applications.
4. Compliance and Certification
Our products comply with all relevant regulations and industry standards. We provide certifications to confirm that each batch of lime meets the necessary quality criteria, giving you confidence in the reliability of our products.
5. Research and Development
Innovation is at the heart of our quality assurance process. Our team continuously explores new formulations and processing techniques to enhance product performance and cater to evolving industry needs.
Our Laboratory Setup
Our laboratory is the cornerstone of our quality assurance efforts. Equipped with cutting-edge technology and advanced instruments, our lab is capable of performing precise chemical and physical analyses, including:
Chemical Composition Analysis Using
XRF (X-ray Fluorescence)
To ensure the highest purity and quality of our lime products, we use X-ray Fluorescence (XRF) technology for chemical composition analysis. XRF is a powerful, non-destructive technique that enables us to accurately determine the elemental composition of our materials. This advanced method allows us to detect and quantify elements such as calcium, magnesium, silica, and more, ensuring that our products meet stringent quality standards.
Carbon – Sulphur Analyser:
At Uma Lime, we ensure the highest quality of our quicklime through rigorous testing using advanced Carbon Sulphur (CS) analysis. This technique measures the carbon and sulphur content in our products by combusting the sample and detecting the resulting gases. CS analysis provides rapid, precise, and reliable results, essential for maintaining the purity of quicklime. By integrating this method into our quality control process, we ensure that our quicklime meets industry standards and customer specifications. Our commitment to thorough testing with CS analysis guarantees high customer satisfaction and compliance with regulatory requirements.
Reactivity
At Uma Lime, we employ both the T-60 Reactivity Test and the HCl Reactivity Test to uphold the highest standards of quality for our quicklime products.
The T-60 Reactivity test measures the time it takes for quicklime to reach 60°C when mixed with water, serving as a key indicator of its reactivity. A shorter T-60 time signifies higher reactivity, essential for diverse applications. Regularly conducting this test ensures consistent product quality, optimizes production processes, and guarantees that our quicklime meets customer specifications and expectations.
Similarly, the HCl Reactivity Test is integral to our quality evaluation process. This method assesses the rate and extent of quicklime's reaction with hydrochloric acid, providing critical insights into its chemical purity and suitability for industrial use. By monitoring the reaction progress and analysing the data, we ascertain the quicklime's reactivity and ensure that only high-quality products are delivered to our customers. Moreover, the knowledge gained from this test informs continuous improvements in our production processes, further enhancing product quality and performance.
Loss On Ignition (LOI):
At Uma Lime, we utilize Loss on Ignition (LOI) testing as a vital quality control measure for our quicklime products. This test determines the amount of moisture, and volatile substances present in the quicklime by measuring the weight loss after heating the sample to a high temperature, typically around 1000°C. The LOI value is essential for assessing the purity and consistency of our quicklime, as it indicates the extent of impurities and residual moisture. By conducting LOI testing regularly, we ensure that our quicklime meets the stringent quality standards required for various industrial applications. This helps us deliver reliable products that consistently meet the specifications and expectations of our customers.
Assessing Lime Content:
At Uma Lime, we prioritize understanding and quantifying both available lime and total lime in our materials. These parameters are essential for ensuring the quality and effectiveness of our limestone and quicklime products. By adhering to ASTM standards such as ASTM C25/C25M-19, we accurately measure and monitor the calcium oxide content in our materials. This rigorous quality control process guarantees that our products meet industry standards and are suitable for a wide range of applications. Whether it's soil stabilization, industrial processes, or environmental applications, our commitment to providing high-quality materials with optimal lime content remains unwavering.
Particle Size Distribution
Accurate measurement of particle size is crucial for the performance of lime in various applications. Our lab ensures that our products are within the desired size range for optimal results.
Commitment to Quality
At Uma Lime, quality is at the heart of everything we do. Our state-of-the-art laboratory plays a crucial role in ensuring that our products meet the highest industry standards. We are dedicated to maintaining exceptional quality control processes that guarantee the satisfaction of our customers.
