YH-60B Type 60 Group Concrete Standard Curing Box

YH-60B Type 60 Group Concrete Standard Curing BoxIt is developed, designed, and manufactured based on GB1345-99 "Cement Standard Consistency Water Consumption Setting Time Stability Test Method" and technical data provided by the Building Materials Research Institute and relevant departments. It is suitable for large, medium, and small cement plants, as well as construction and engineering departments for the setting and curing of concrete and cement specimens.

YH-60B Type 60 Group Concrete Standard Curing BoxOn the basis of the original product, a series of improvements have been made. The box door is sealed with magnetic tape, and the insulation layer is made of insulation cotton with good insulation effect. A refrigeration unit is added inside, which runs smoothly and has low noise. The heater is made of copper tube processing, rust and corrosion prevention, humidification device, beautiful appearance, and high precision of controller temperature control and humidity control. A user troubleshooting and maintenance table has been added in the user manual as a basis for users to provide records to the factory during maintenance, so that our maintenance box can be improved in the production process and the product can be made durable to meet the user's requirements.

YH-60B Type 60 Group Concrete Standard Curing BoxStructure and working principle:

1. Structure

The box is made of two layers, inner and outer, consisting of an outer box and an inner box. The outer box is made of high-quality cold-rolled steel plate, the inner box is made of stainless steel plate, and the shelves are made of stainless steel profiles, with good corrosion resistance. The water tank below the inner box is used for heating and auxiliary humidification. The humidification system mainly uses ultrasonic humidification instruments, supplemented by water heating and evaporation. The automatic control system is controlled by temperature and humidity control instruments to cool according to the given temperature and humidity, and automatically switch between heating and humidification. The temperature and humidity inside the box are displayed digitally by the instruments.

2. Working principle

Temperature control: When the temperature inside the box is lower than the lower limit set value of the temperature controller, the temperature controller outputs a heating signal to command the electric heating element to start working. Conversely, when the temperature is higher than the upper limit set value, the temperature controller commands the refrigeration system to work. When the temperature inside the box reaches the required value, it automatically stops heating or cooling.

Humidity control: Ultrasonic humidifier is used for humidification, which can ensure that the humidity inside the box reaches ≥ 95%. The humidification device is automatically controlled by a temperature controller. When the humidity is less than 95%, the temperature controller commands the humidifier to work. After reaching the hysteresis value, it automatically stops working. The hysteresis value should be adjusted to 0-1 ℃ and should not be too large.
