Permanent antistatic thick china antistatic principle:
1, permanent antistatic thick china, is divided into: two-layer up and down, upper strata is the antistatic backing of polychrome panel, mainly absorbs air static; Lower floor is black conductive panel, and Main Function is: polychrome panel antistatic backing absorbs air static and static discharges by lower black conductive plate, has protected like this safety of product in manufacturing process.
2, upper strata Multilayer panel is mainly to add the special electrostatic material of certain proportion, this electrostatic material can be passed through high temperature extrusion in HIPS inside, inner and the surface formation conductive path leakage electric charge at HIPS, and be not subject to outside natural conditions (humidity, alcohol cleaning) impact reaches a kind of effect of permanent antistatic, it is different from other liquid electrostatic material, by migration product surface and air moisture, give and be combined in HIPS surface and form a kind of antistatic film and carry out conductive path leakage electric charge, after this tunic is rubbed off, HIPS is the anlistatig ability of tool not, also return to former front insulator state.
3, black bottom, mainly relies on conductive carbon powder to be added on HIPS by high temperature extrusion, forms surface and inner conductive path, and not changed by natural conditions affects anti-static effect.
Double layer multicolor permanent antistatic thick china of the present invention, volume resistance≤10
7Ω cm, static releasing effect is good, in one second, from 5000V-500V voltage, and can make different purposes polychrome Anti-static veneers, pass through " national antistatic supervision inspection center " simultaneously and detected various technical indicators and surpassed common Anti-static veneer on market.
And Anti-static veneer of the present invention is two-layer compound; form up and down path and reveal electric charge; in two-layer employing, add the special powder static electricity material of type; this material adds HIPS, forms core shell structure by high temperature extrusion in parent, and at the inner and surperficial path that forms of HIPS, reveals electric charge with this; this technological design can make the surface electrostatic of antistatic backing by black conductive layer, be derived and be gone very soon; and speed is fast, can make free charge be deposited in product surface, thereby protect product safety in the mill.The permanent antistatic thick china of our factory exploitation does not have animal migration, volume resistance is low, static rate of release is fast, and antistatic has permanently, and it is different from other products and moves to product surface and rub off the fatal shortcoming that just there is no antistatic effect by static liquid.The difficult problems such as therefore, the thick china of our factory permanently antistatic is succeeded in developing, and has solved electron trade Anti-static veneer short former service life, is subject to effect of natural conditions large, and antistatic effect is undesirable.
