LEISA RC Resin Content Testing Service

Resin content testing service

Service Content

Resin content is an important performance indicator of composite materials such as glass fiber reinforced plastics, which affects the mechanical properties, corrosion resistance and service life of the material. Raysa Technology Laboratory provides professional resin content testing services to ensure that the quality and performance of the material meet the expected requirements.

Testing standards

• The test is carried out according to GB/T 2577-2005 Test method for resin content of glass fiber reinforced plastics.

Detection method

• The resin content was determined by the loss on ignition (LOI) method.

Testing process

1. Sample Receiving and Registration

   • Sample requirements : The customer provides the samples to be tested. The samples should be representative and of moderate size.
   • Information registration : Record sample information in detail, including sample name, quantity, provider, etc.

2. Sample pretreatment

   • Cutting and weighing : Cut the sample into appropriate sizes, weigh it accurately, and record the initial weight (W1).
   • Constant temperature drying : Place the sample in a drying oven at 105°C and dry it to constant weight, and record the weight after drying (W2).

3. Test preparation

   • High temperature furnace preheating : Preheat the high temperature furnace to the specified temperature (usually 600°C).
   • Sample loading : Place the dried sample into the crucible and accurately weigh the total weight (W3).

4. Detection execution

   • Burn-out process : Heat the sample to 600°C in a high temperature furnace and keep it for a period of time (usually 30 minutes) to allow the resin to burn completely.
   • Cooling and weighing : After the sample has cooled to room temperature, accurately weigh the remaining sample (W4).

5. data analysis

   • Resin content calculation : Calculate the resin content according to the following formula:
     $$\text{<span class="katex-display"><span class="katex"><span class="katex-mathml">Resin content</span></span></span>}<span\; class="katex-display"><span\; class="katex"><span\; class="katex-mathml">(</span></span></span>\mathrm{<span\; class="katex-display"><span\; class="katex"><span\; class="katex-mathml">\%</span></span></span>}<span\; class="katex-display"><span\; class="katex"><span\; class="katex-mathml">)</span></span></span><span\; class="katex-display"><span\; class="katex"><span\; class="katex-mathml">=</span></span></span>\frac{\mathrm{<span\; class="katex-display"><span\; class="katex"><span\; class="katex-mathml">𝑊</span></span></span>}\mathrm{<span\; class="katex-display"><span\; class="katex"><span\; class="katex-mathml">3</span></span></span>}<span\; class="katex-display"><span\; class="katex"><span\; class="katex-mathml">-</span></span></span>\mathrm{<span\; class="katex-display"><span\; class="katex"><span\; class="katex-mathml">𝑊</span></span></span>}\mathrm{<span\; class="katex-display"><span\; class="katex"><span\; class="katex-mathml">4</span></span></span>}}{\mathrm{<span\; class="katex-display"><span\; class="katex"><span\; class="katex-mathml">𝑊</span></span></span>}\mathrm{<span\; class="katex-display"><span\; class="katex"><span\; class="katex-mathml">3</span></span></span>}<span\; class="katex-display"><span\; class="katex"><span\; class="katex-mathml">-</span></span></span>\mathrm{<span\; class="katex-display"><span\; class="katex"><span\; class="katex-mathml">𝑊</span></span></span>}\mathrm{<span\; class="katex-display"><span\; class="katex"><span\; class="katex-mathml">2</span></span></span>}}<span\; class="katex-display"><span\; class="katex"><span\; class="katex-mathml">\times </span></span></span>\mathrm{<span\; class="katex-display"><span\; class="katex"><span\; class="katex-mathml">100</span></span></span>}$$ Resin content ( % ) = W 3 − W 2 W 3 − W 4 × 100

6. Report Preparation

   • Report content : including sample information, test methods, test conditions, resin content calculation process and result analysis.
   • Quality review : Data review and report preparation are performed by professional technicians.

7. Results Feedback

   • Report delivery : The test report will be delivered to the customer in electronic or paper form.
   • Technical consultation : Provide result interpretation and technical consulting services to answer customers' questions.

service advantage

• Professional equipment : Use high-precision high-temperature furnace and weighing equipment to ensure the accuracy and reliability of the test results.
• Technical team : We have an experienced technical team that can provide professional analysis and technical support.
• Quick response : Efficient service process ensures that the test is completed and the report is provided in the shortest time.

Through the above systematic testing process, Lesa Technology Laboratory can provide customers with reliable resin content testing services to help customers ensure the performance stability and safety of materials in actual use.
