The machine has three vertical or horizontal stations available for customized and is easy to operate. Loading, unloading and measurements are also much easier to carry out with the workstations provided. The sample flexes at speed of 140 times per minute, and the exact number is recorded in a counter that has been preset to the required number of flexing. A fixture can be used to position the steel chisel, which can be used to support the sample after the initial chipping. All mobile parts that need access are fully protected with a fully interlocked security cover to ensure that the machine complies with the latest security regulations. A manual device can be used to measure the hardness of the outer bottom and check whether the outer bottom must be twisted in accordance with EN ISO 20344. UTS also provide a version of this machine for testing at low temperatures allowing tests to be conducted down to -20°C.

Water Resistance Tester
Shoe Water Resistance Tester H009

To determine the waterproofness property for finished shoes. Within the specified depth of water, whole shoe will be mechanically brushed by rotary wet brush, so as to measure the water penetration property for finished shoe.

NBS Abrader - Abrasion Tester
NBS Rubber Abrasion Tester H014

To determine the abrasion resistance property for rubber or other compounds, sole and heel materials which are not less than 2.54mm in thickness. This machine has memory function so that users can set the number of tests by themselves. The current records will be kept not to change even if power failure or stop occurs. It also can be connected to a cleaner for easy cleaning.

astm d1424  Elemendorf Tear Tester
Digital Elemendorf Tear Tester M006B

High temperature aging box features and common failure maintenance

2019-05-06

Application: this product is suitable for rubber, plastic, artificial leather, wire, cable, insulator or coated rubber test piece and other synthetic products to test the aging, elongation and tensile strength of the material and compare the tensile strength and elongation of the test piece before and after aging.The machine adopts hot air circulation to promote the aging of test pieces, and the inner box has strong airtightness.

Structure and characteristics of high temperature aging box:

1. The large observation window is equipped with a light to keep the box bright, and the tempered glass is used to clearly observe the status of the box at any time;

2. The hot air circulation system is composed of fans that can operate continuously under high temperature and special air ducts, and the temperature in the working room is even;

3. Aging box device is equipped with low speed rotary table;

4. The box insulation is made of ultra-fine glass fiber insulation cotton, which can avoid unnecessary energy loss;

5. There is a 50mm test hole on the left side of the box, which can be used for external test power line or signal line;

6. The time and frequency of ventilation can be set arbitrarily;

7. Control precision, plus or minus 0.1 ℃;

8. Temperature sensor: PT100 platinum resistance

9. Key input, digital display;

10. The automatic calculation function of p. i. D can reduce the inconvenience caused by manual setting;

11. During operation or setting, warning signals will be provided in case of errors;

12. The machine USES hot air circulation to promote the aging of test pieces, and the inner box is highly airtight;

13. It is equipped with air device for changing the inner box and automatic cut-off protection device for over temperature.

High temperature aging box common failure solutions and daily maintenance

1. Find out whether the applied voltage is consistent.(AC220V, 7KW) into the test sample.

2.When the "POWER" button is turned on, the POWER supply will be on when the POWER indicator is on, and then set the temperature controller according to the required temperature adjustment. For detailed temperature operation, please refer to the PID temperature controller operation instructions.

3. Air change adjustment method: open the vent and air inlet (air change control valve) to the appropriate position (low temperature, large hole;High temperature, the opposite.In case of more than one air change, please fully open the vent, the air change regulating valve clockwise to open, counterclockwise to close (left to close, right to open).The air change switch should be opened only when the number of air changes is large. Generally speaking, it is enough to open the vent and air inlet (air change control valve) to the proper position.

4. The PV display temperature is the actual measured temperature.SV display temperature is the set temperature.

5.Turn on the timing switch, adjust the test time, close the door, the operation will automatically stop after the time

6.Air volume calculation formula N=3590 (p1-p2) /V*d* delta T

N- air change (times/hour)

P1- average electrical power consumed when the air passage is opened (W);

P2- average electrical power consumed when the air passage is closed (W);

△T - the difference between the arithmetic mean of the temperature in the cabinet and the environment temperature (℃);

△V- studio volume (L);

D - air density at ambient temperature (g/L).

The expansion and contraction of a gas is the most obvious.A gas is also easily compressed.Therefore, the density of a gas is most affected by temperature and pressure. When you say the density of a gas, you must specify the conditions (temperature and pressure).The temperature rise per 1 ℃, the air density decreased 0.000042 grams per cubic centimeter.

0 to 0 ℃.001293 grams per cubic centimeter 10 to 0 ℃.001,247 grams per cubic centimeter.

When 20 ℃ to 0.001205 grams per cubic centimeter at 30 ℃ to 0.001165 grams per cubic centimeter.
