Insulating gloves are a kind of protective gloves for protecting the hands when they are to be operated on DC electrical equipment with AC voltage of 10kV and below and 10kV voltage.
Insulating gloves must have good electrical properties and high mechanical properties, hardness of 30 ° to 35 °, and have soft properties. And it should meet the requirements of GB17622-1998 "General technical conditions for insulating gloves for live working", the main technical indicators are:
1. Electrical performance Insulating gloves must have good electrical insulation properties. The test voltage waveform, test conditions and test procedures should comply with the provisions of BG/T16927.1-1997.
2. Anti-aging performance After the heat aging test, the measured values ​​of tensile strength and elongation at break of the insulating gloves should be more than 80% of the values ​​measured without the heat aging test gloves. Tensile permanent deformation should not exceed 15%.
3, low temperature resistance Gloves according to the specified method after the low temperature test, under the force of the situation, there should be no breaks, cracks and damage after visual inspection, and should pass the insulation test without moisture absorption treatment.
4. Flame resistance After the flame has passed the burning test according to the specified method, the flame spread of the burning test flame on the glove is observed after the flame exits. Wait 55s, if the burning flame does not spread to the 55mm reference line at the end of the glove, it is a qualified product.
5, mechanical properties a, tensile strength and elongation at break The average tensile strength of the glove should not be less than 14MPa, the average elongation at break should not be less than 600%
b. Tensile permanent deformation The deformation should not exceed 15%.
c. Anti-piercing force The mechanical piercing force should not be less than 18N/mm
With these guarantees, quality protective gloves can be made.

How to clean and maintenance the WPC floor products ?
*Pollution occurred from moulds,mucedine,berry and leaves,use a cleaning agent contains detergent and sodium hypochlorite to clean of.
*Dirt or debris: clean the decking to remove dirt or debris by using soap,hot water and astiff bristle.
*Chalk markings: all colored chalk lines are permanent except white,surubbing the area with hot soapy water with bleach may dislodge some of the chalk.
*Oil and olein occurred by touching: use a cleaning agent contains degreasing agent.
*Use tool clear the miscellaneous articles or objects of the profiles space in order to keep good drainage.
