It is a kind of banded-shaped insulation material woven by polyester fiber. It has heat resistance and insulation property. It is used for coil binding and fastening on transformers, reactors, electric motors and other products, and has high heat shrinkage rate, high hot tensile strength, no loose or dropping, and no pollution to the oil.
Structure: plain weave
According to different shrinkage rates, it is divided into: electrical polyester high shrinkage tape(shrinkage rate 40% ~ 45%) / electrical polyester low shrinkage tape(shrinkage rate 18% ~ 23%).
1, human body temperature measurement: accurate measurement of human body temperature, replace the traditional mercury thermometer. Women who want to have children can use infrared thermometer (frontal temperature gun) to monitor basal body temperature at any time, record body temperature during ovulation, and choose the right time to conceive, and measure temperature to determine pregnancy.
Of course, the most important thing is to always observe whether your body temperature is abnormal, to avoid influenza infection, and to prevent swine flu.
2. Skin temperature measurement: To measure the surface temperature of the human skin, for example, it can be used to measure the surface temperature of the skin when it is used for re-implantation of a limb.
3. Object temperature measurement: measure the surface temperature of the object, for example, it can be used to measure the temperature of the tea cup.
4, liquid temperature measurement: measure the temperature of the liquid, such as the temperature of the baby's bath water, measure the water temperature when the baby is bathing, no longer worry about cold or hot; you can also measure the water temperature of the milk bottle, easy to prepare Baby's milk powder;

In addition to the filtering efficiency of the N95 mask, the closeness of the mask to the face is one of the important factors determining the effectiveness of the mask. Different types of masks have large differences in their suitability to the human face. Therefore, before using a mask, the suitability of the mask should be checked first. During the tightness test of the wearer's face, ensure that air can pass in and out through the mask when it is close to the edge of the face.
