The season of alternating autumn and winter is a good time to maintain high and low temperature testing machines. Many people's high and low temperature testing machines need to be cleaned at this time. If these problems are neglected, then the test box will be damaged more or less in the long run. . The following small series will tell you about some methods of maintaining high and low temperature testing machines during the autumn season.

HDPE ( Uniaxial geogrids(ux Geogrid) ) : Ultimate Tensile Strength 30kN/m to 300kN/m, HDPE geogrids (Uniaxial ) range : Flexurally stiff biaxial monolithic and integrally formed geogrid constructed of PP- Polypropylene or HDPE – polyethylene by a unique punching and drawing process .
1. It reinforce old asphalt concrete road surface and asphalt layer, and prevents damage ;
2. It is used for rebuilding cement concrete road surface into composite road surface and restraining reflection caused by block contraction .
3. It is used in road expansion and improvment project and crack caused by old and new combination position and uneven sedimentation ;
4. It is used in soft soil base reinforcement treatment , is favorable for soft soil water separation and concretion,restrains sedimentation effectivly,distributes stress uniformly and improve overall strength of road base;
5. It is sued for preventing contraction crack caused by new road semi-rigid base layer,and reinforces and prevents road surface crack caused by foundation crack reflection.
First, the interior of the high and low temperature testing machine should be cleaned regularly, and the stain on the magnetic stripe of the door should be wiped off as soon as possible. Otherwise, the door seal will be accelerated and the sealing performance of the door will be affected, causing the temperature inside the box to rise and power consumption. The increase in volume, especially the lower door seal, is more likely to be contaminated and should be checked frequently.
Second, clean the surface of the condenser and compressor, do not wipe with water, use a brush to remove dust to ensure good heat dissipation conditions. Do not use strong corrosive liquids such as alcohol, benzine, washing powder, or acid solution when cleaning.
Third, the sample holder that can be removed inside the high and low temperature testing machine can be washed with water. When cleaning the surface of the high and low temperature tester and the door seal, turn off the power, wipe it with a soft cloth dampened with warm water or soapy water, and finally wipe it with water and wipe it dry. Do not flush with water inside or outside the high and low temperature test machine to avoid leakage or malfunction.
Fourth, regular defrosting. After working for a period of time on the high and low temperature tester, the surface of the evaporator inside the box will form a layer of frost. If the thickness of the frost layer exceeds 6 mm, the cooling effect will be reduced and the power consumption will be increased. Therefore, the defrosting should be performed regularly.
