new arrival! TD741-1 automatic vacuum sealing instrument for asphalt mixture solves the testing problem of high water absorption mixture

Recently, Hebei Tianqi Xingzi Testing Equipment Co., Ltd. (hereinafter referred to as "Tianqi Xingzi") officially launched a testing and development system specifically designed for high water absorption asphalt mixturesTD741-1 Automatic Vacuum Sealing Instrument for Asphalt MixtureThe device focuses on the detection pain points of open graded or high porosity mixtures (water absorption rate>2%) such as SMA and OGFC, and provides a more reliable volume index testing solution for the field of road engineering material testing with high-precision automated sealing technology, repairing the accuracy gap of traditional detection methods in high water absorption specimen testing.

As the core link of road engineering quality control, the volume indicators such as gross volume density and void ratio of asphalt mixture directly affect the impermeability, durability, and bearing capacity of the road surface. However, open graded mixtures such as SMA and OGFC have high porosity and water absorption rates greater than 2%. In traditional testing methods, water often seeps into the interior of the specimen due to poor sealing, resulting in data deviation and making it difficult to meet the strict requirements of engineering for testing accuracy.

In response to the pain points in this industry, Tianqi Xingzi has achieved a key technological breakthrough with the TD741-1 automatic vacuum sealing instrument, which relies on years of experience in developing testing equipment. The equipment, through an intelligent automatic vacuum pumping system, can create a tightly sealed vacuum environment between the specimen and the sealed bag to complete the sealing process, effectively eliminating the hidden danger of moisture infiltration from the source and ensuring the accuracy of the results of the relative density, bulk density, and connectivity porosity tests. At the same time, the equipment strictly follows the latest industry standards such as the "Test Regulations for Asphalt and Asphalt Mixtures in Highway Engineering", and the temperature control accuracy of the test environment reaches 25 ℃± 0.5 ℃. It is equipped with 4300ml × 2 large capacity containers, 0-100kPa precise pressure control, and 120W high-efficiency exhaust fan to further ensure the stability and data reliability of the testing process.

In terms of core parameters and practical design, TD741-1 equipment also performs outstandingly. Its power supply voltage is compatible with 220V ± 10% civilian and laboratory circuits, and the 30W vibration machine can assist in fitting the test piece to the sealed bag. The compact shape of 530 × 500 × 360mm is convenient for laboratory layout, which can meet the mix proportion verification needs of asphalt mixture production enterprises and also adapt to the daily testing work of third-party testing agencies and highway engineering quality inspection departments, providing full scene support for the quality control of high-performance asphalt mixtures such as SMA and OGFC.

The person in charge of Hebei Tianqi Xingzi Testing Equipment Co., Ltd. said: "The launch of TD741-1 automatic vacuum sealing instrument is another practice of Tianqi Xingzi's research and development concept of 'solving industry pain points with technology'. In the future, the company will continue to focus on the technical needs in the field of road engineering inspection, launch more high-precision and intelligent inspection equipment, and contribute to the improvement of road engineering quality and industry technological progress. ”

At present, the TD741-1 automatic vacuum sealing instrument for asphalt mixtures has been officially opened for ordering. Tianqi Xingzi can provide customers with one-stop services such as equipment installation and commissioning, operation training, and after-sales technical support.
