Brief description
The freeze-thaw testing machine can be used as freeze-thaw testing equipment for concrete slow freezing method, wall bricks, hollow blocks, aerated concrete and other building materials. This freezing and thawing machine uses the method of freezing in the air and thawing in water to conduct periodic freezing and thawing tests. The test has a high degree of automation. It can automatically complete multiple freeze-thaw cycle tests with one setting. No operations are required during the test to meet the requirements of relevant standards for freeze-thaw tests on specimens. It is the current best choice for frozen building materials. Ideal equipment for melt testing.
Artificial simulated environment test is a scientific summary of the actual environmental impact and has the characteristics of typification, standardization, ease of use, and ease of comparison. The diversification of environmental conditions and the importance of environmental testing also put forward more stringent requirements for environmental testing equipment.
The series of freeze-thaw testing machines are in accordance with the national industry standards and the national standard B/3-B/-Geotechnical Test Method Standard and B/"Test Method for Wall Bricks", B/-"Long-term Performance and Durability Test of Ordinary Concrete" Method", B/-"Test Method for Small Hollow Concrete Blocks", B/-"Test Method for Air-entrained Concrete", and can be used as wall bricks, hollow blocks, air-entrained concrete, etc. Test equipment for slow freezing and thawing of specimens.
After long-term use by users, it is confirmed that the product has high reliability, providing important quality assurance for long-term performance and durability performance tests of wall tiles and concrete, and can satisfy research institutes, universities, design, and The need for rapid frost resistance testing of concrete in construction, quality inspection and other departments.

Equipment structure
The equipment shell is processed and formed by high-quality 3 steel plate CNC machine tools, and the surface of the shell is sprayed with plastic. It is more smooth and beautiful
The inner tank is made of 3 high-quality stainless steel plates, and the outer side of the inner tank is reinforced with ribs to avoid deformation of the overweight inner tank
The testing machine uses a temperature LCD controller (with its own communication interface) , the temperature is displayed directly, and the operation is simple
< r::\~\~\~\\\. The controller operation interface is available in Chinese and English,
The real-time operation curve can be displayed on the screen
Control method: Thermal balance temperature and humidity regulation method
Temperature sensor: Platinum resistance temperature measuring body
It has the function of automatic calculation, which can immediately correct the temperature change instrument appearance diagram
conditions, so that Temperature control is more accurate and stable
The controller operation interface is available in Chinese and English, and the real-time operation curve can be displayed on the screen
The controller can set program groups, each group of programs has a maximum setting step, each Program groups can be connected. Full cycle, maximum number of times, partial cycle, maximum number of times.
. The inner sample holder is made of stainless steel square tube welded and can bear approximately 100,000 pounds without deformation
. Insulation material: high-density foaming agent. The thickness of the insulation layer is The temperature will not be transmitted to the outside of the equipment, ensuring a balanced and stable temperature in the laboratory
. The bottom frame of the equipment is reinforced by channel steel mesh welding
. The equipment box cover adopts an extended handle, and there are no additional handles on both sides. The air source is supported by a gas spring strut, which is easy to open
. The drainage valve is installed at the bottom of the left side to facilitate the discharge of sewage
. The control part of the equipment is designed on the right side of the equipment, making it easy to operate, simple and easy to maintain.
, Use stainless steel electric heaters, reasonably distributed in the lower part of the box (away from the bottom of the box)
, Built-in water circulation pump, and a filter screen is installed at the water inlet to prevent clogging of the water pump pipeline
