Where can I go to get a comprehensive solution for dry shrinkage testing? BAIJIAN Materials Testing Agency provides dry shrinkage testing services. It is a national high-tech enterprise, a third-party materials laboratory, a CMA qualification certification agency, and a collectively owned scientific research institution with complete laboratory instruments. , a strong scientific research team, adhering to the concept of scientific research and dedication, engaged in performance testing, non-standard testing, unknown substance detection and identification, industrial problem diagnosis and testing, composition testing, failure testing, corrosion testing, etc. Test reports will be issued in 7-15 working days to support The QR code system checks authenticity, and multiple laboratory branches across the country support nationwide door-to-door sampling/sample delivery testing services.

Test period: 7-15 working days

Testing fee: Initial inspection of samples. After the initial inspection, a quotation will be made based on the customer's testing needs and the complexity of the experiment.

Dry shrinkage test range

Yarn, mortar, wood, concrete, board, cement, mortar, polyester filament, air-entrained block, etc.

Test items

1. Dry shrinkage definition: the volume reduction ratio of a material due to loss of moisture during the drying process.

2. Drying method: Air drying, vacuum drying and other methods are usually used for drying. The drying temperature and time need to be determined according to the specific materials.

3. Test conditions: The dry shrinkage test needs to be carried out under standard test conditions, including parameters such as drying temperature, relative humidity and time.

4. Sample preparation: The sample needs to be prepared in accordance with standard requirements, usually in the shape of a cuboid or cylinder.

5. Test equipment: Commonly used dry shrinkage testing equipment include density meters, dilatometers, electronic balances, etc.

6. Experimental process: Dry the sample under standard conditions, record the mass, volume and other parameters of the sample, and measure the change in sample volume within a certain time interval.

7. Data processing: By calculating the initial volume and the volume after drying of the sample, the drying shrinkage rate of the sample can be calculated.

8. Influencing factors: Dry shrinkage is affected by factors such as material type, moisture content, temperature and humidity.

9. Application scope: Dry shrinkage test is widely used in fields such as building materials, wood, soil and ceramics.

10. Significance and value: Measuring dry shrinkage can understand the physical properties and preparation process of materials, provide basic data for design and use, and also help optimize the performance and quality of materials.

What does the BAIJIAN test report do? What problems can it help you solve?

1. Sales report. (Sales need to provide third-party testing reports to make their products more unique, let the product data speak for themselves, and make customers more confident.Depend on the quality of your own products. )

2. R&D report. (In the process of developing new products, we encountered some thorny issues about ingredients. We used third-party testing data to find the cause of the problem, solve the problem in a timely manner, shorten the R&D cycle, and reduce R&D costs)

3. Improve products quality. (Discover problems with your own products through comparison of third-party testing data, improve product problems, improve quality, and reduce production costs)

4. Use of scientific research paper data.

What are the advantages of BAIJIAN material testing laboratory?

1. Collectively owned testing institution with complete qualifications and scientific, fair and accurate test reports.

2. Multiple laboratory branches are located across the country, supporting door-to-door sampling/sending samples for testing.

3. The testing cycle is short, the testing cost is low, and the experimental plan is more complete.

4. For initial inspection of samples, no testing fees will be charged during the initial inspection.

5. The test report supports scanning the QR code to check the authenticity.

BAIJIAN testing process

1. Send samples. (Communicate with engineers, submit your own testing requirements and send samples to our research institute)

2. Initial inspection samples. (After receiving the sample, conduct a preliminary inspection of the sample and formulate a detailed experimental plan)

3. Quotation. (After the initial inspection, a quotation will be made based on the customer's testing needs and the complexity of the experiment)

4. Both parties confirm, sign a confidentiality agreement, and start the experiment.

5. It takes 7-15 working days to complete the experiment.

6. Mail the test report and provide post-service.

The above is the relevant introduction to the dry shrinkage test. If you have other needs, you can consult the laboratory engineer to help you solve it.
