SBY-32B cement specimen constant temperature water curing box

I. Overview:

The instrument is designed and produced according to the new national standard GB-17671-1999 "Cement Mortar Strength Test Method ISO Method" for the maintenance requirements of cement mortar specimens. The inner tank and water tank are made of stainless steel plates, and the curing is divided into pools. The water tank is equipped with sliding wheels and guide rails to facilitate the pushing and pulling and taking out of the specimen. Computer intelligent instrument, double-layer vacuum glass door. Suitable for scientific research, construction, colleges and universities, testing centers and other units.

II. Principle and Structure

1. The outer box of the sub-tank cement constant temperature water curing box is made of high-quality steel plate, and the inner tank and sub-tank water tank are all made of stainless steel, which has good corrosion resistance and thermal conductivity. The sub-tank water tank is equipped with sliding wheels and guide rails, which can be easily pushed, pulled and taken out.
2. The curing box adopts an intelligent digital display temperature controller. When the water temperature is higher or lower than the set temperature, the heating pipe or refrigerator is automatically switched to generate cold air or heating. Then, the centrifugal fan specially installed in the box can quickly even out the air temperature and keep the water temperature within the range of 20℃ ±1℃.

Function of the SBY-32B Cement Specimen Constant Temperature Water Curing Tank

The SBY-32B cement specimen constant temperature water curing tank is a specialized laboratory device designed to provide a standardized, temperature-controlled curing environment for cement specimens (such as cement mortar strength test blocks). Its primary purpose is to simulate standard curing conditions, ensuring that cement specimens undergo proper hydration under specific temperature and humidity settings, thereby obtaining accurate and comparable mechanical performance test data. Below are its key functions and features:

1. Core Functions

• Constant Temperature Curing
  Maintains water temperature at 20±1°C (complying with the Chinese national standard GB/T 17671-1999 "Method of Testing Cements—Determination of Strength"), ensuring stable curing conditions and preventing temperature fluctuations from affecting the hydration process.
• Promotes Standard Hydration
  The constant-temperature water bath allows cement specimens to fully absorb water, ensuring saturated humidity (without additional humidification) and avoiding strength deviations caused by drying shrinkage or uneven moisture distribution.
• Batch Curing
  Can accommodate multiple sets of cement specimens simultaneously (e.g., 32 sets or as per model capacity), improving testing efficiency and ensuring uniform curing conditions for all specimens in the same batch.

2. Key Features

• Precise Temperature Control
  Equipped with a high-sensitivity temperature control system (e.g., PID regulation) and a circulating water pump or heating element to ensure uniform and stable water temperature.
• Corrosion-Resistant Design
  Typically made of stainless steel or anti-corrosion materials to prevent rust from long-term exposure to water and cement specimens.
• User-Friendly Operation
  Features such as automatic water replenishment, water level control, and over-temperature protection minimize manual intervention, meeting the automation needs of modern laboratories.

3. Applications

• Cement Quality Testing
  Used by cement manufacturers, construction companies, and quality inspection agencies to ensure specimens are cured in compliance with ISO or GB standards, providing reliable samples for compressive/flexural strength tests.
• Scientific Research & Comparative Experiments
  In material research, where controlled conditions are critical, the constant-temperature water curing tank provides highly repeatable experimental environments.

4. Key Considerations

• Regular Calibration: Temperature sensors and control systems should be periodically verified for accuracy.
• Water Quality Management: Use purified water to prevent scale buildup that may affect temperature control components.
• Specimen Placement: Specimens should be spaced appropriately to avoid obstructing water circulation.

By providing a stable curing environment, the SBY-32B plays a vital role in ensuring the reliability of cement strength test results, making it an indispensable piece of equipment in cement performance evaluation laboratories.
