Sticky mat laying method
1, the basic requirements of the ground :
① ground to be flat , no significant irregularities , roughness less than two thousandths .
② basis of the ground floor for the mill , ceramic floors, wood floor .
③ ground should have enough strength and no sand , shell phenomenon .
④ ground be dry . 2 , anti-static
Sticky mat construction procedures and specific methods:
① with 120 # gasoline or xylene cleaning the ground impurities ( with washing machine ) ;
② floor laying a copper bar or aluminum , such as copper strip having a thickness of 0.02mm, width of 30mm, the number of floor coverings according to the actual requirements to determine the length and number , with the laying of the copper bar to the end toward the ground .
③ Ground guide grid after laying , clean and dry ground , painted conductive glue to dry for 20-30 minutes , until the stick in hand , anti-static Sticky bottom surface ( black face ) the same as ( once coated with conductive adhesive ) , then the antistatic mat and sticky adhesive surface , and then re- roll rolling 5 times, so that the surface of the anti- static sheet can be neatly straight , after 48 hours at room temperature can be used.
④ ambient temperature requirements during the construction of not less than 25 degrees Celsius and humidity less than good ventilation .
⑤ conductive glue resistivity less than 108Ωcm, peel strength Kg/2.5cm.
⑥ gap between the conductive coating conductive glue can be used , can also be pasted on the surface of the copper strip . Sticky mats electrostatic surface resistance is the material between two points on a face of the DC voltage and current through the ratio of units in ohms . Material resistance characteristics described surface resistivity usually or volume resistivity . Surface Resistivity, simply the same surface between the two electrodes measured the resistance value , the electrode shape, and the resistance value is obtained by calculating the combined resistance value per unit area .
Anti-static mats sticky material thickness volume resistivity is defined by the resistance value , the unit is Ω • cm. Generally the surface resistance with a surface resistance measuring instrument can measure . "Ohms / sq", i.e. Ω / square meter (square), the " surface resistivity " of the unit.
