Glass bottle cold and thermal shock strength meter - recommended

Glass bottle cold and thermal shock strength meter - recommended first we to understand what is thermal shock, thermal shock refers to due to sharp heating or cooling, so that the object in a short period of time to produce a large amount of heat exchange, temperature changes dramatically, the object will produce shock thermal stress, this phenomenon is called thermal shock
.

In recent years, 71% of the world's liquid filling products are the use of glass bottles, and China is also a country with a high proportion of glass bottles in the world, accounting for 55% of the global glass bottles, which has exceeded 50 billion per year, glass bottles as the mainstream packaging, after a century of packaging vicissitudes, still with its stable material structure, pollution-free, low price and other advantages by the favor
of various industries.

However, in the process of transportation and use, the glass bottle will also receive the influence of environmental factors to crack the phenomenon, of which temperature change is a very important factor, Jinan Sanquan Zhongshi Experimental Instrument Co.
, Ltd.
production of glass container thermal shock meter, is a can simulate the temperature difference, so as to detect glass products anti-cold and thermal shock detection testing machine
.

Procedure for use: 1.
Press the red button before loading the experimental parts, the hanging beam of the metal basket can be removed from the lifting seat, the hanging beam is fixed to the lifting seat with a stop that can be rotated, and the block in the metal basket is installed as needed, and the cover plate of the metal basket has two types, which are used for large and small glass products
.

Place the water-filled test specimen into a metal basket and press the cover
plate.

After hanging, open the red button
.

2.
Heat up to the required temperature, triac automatic temperature
control.

(If the temperature control accuracy is required for the second use, PID tuning can be carried out, and the method can be found in the instrument manual.

)
）3.
Adjust the position
of the limit block above the lifting guide rod according to the trough time.

The 5 cm slotting time of the limit block from the upper end is 15 seconds, and the 15 cm slotting time of the limit block from the upper end is 12 seconds
.

4.
Press the green button The instrument automatically works according to the program, the metal basket stays in hot water for 15 minutes and then rises and rotates into cold water, and the tank stays in cold water for 30 seconds before resetting
.

5.
Press the red button at work To stop the machine, and then press the red button to return to the original position
of the metal basket.

Technical parameters Temperature difference range 0-60 °C (adjustable) temperature control accuracy 1 °C capacity High temperature tank 31L Low temperature tank 56L cold water constant temperature time 1-30000s (adjustable) Hot water constant temperature time 1-30000s (adjustable) Hot and cold water conversion time 10±2s Dimension 880mm×530mm× 1300mm (length, width and height) Weight 48kg Working temperature 5°C-40°C Relative humidity 80%, non-condensing power 220V 50Hz Glass bottle cold and thermal shock strength meter - recommended
