At present, there are a large number of high-brightness backlights emerging in the market. However, the yield rate has not been high (between 88% and 93%). The labor and operating costs are getting higher and higher. The unit price of a product is pressured by customers and the yield rate is not high. Under high circumstances, there is basically no profit. How can we improve the product yield rate? ? In the bad products you will find most of the bad (40-50%) is made of static electricity, micro dust. Solving electrostatic and dust problems can increase 3-5% yield. Electrostatic Solution (1) Reasons for the generation of static electricity:
Biaxial Geogrid(bx geogrid) is made of high molecular polymer through extrusion, forming and punching before longitudinal and lateral stretching. This material has considerable tensile strength in longitudinal and lateral directions. This chain structure can effectively bear and diffuse forces on soil and is applicable to large area permanent load bearing foundation as a reinforce.
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.

1. Die-cutting machine, slitting machine, laminating machine, film laminating machine itself with static electricity 2, electronic material own static large 3, material surface and friction on the device generate a lot of static electricity 4, winter climate dry and increase the material surface Static electricity 5, human body static electricity (2) electrostatic impact on production
1, affect the precision of die-cutting, lamination, film and sheet mutual repulsion of inconvenient die sheet, laminating, finishing, packing and coiling of the coiled material. 3, static electricity has adsorption force, static electricity on the surface of the material will absorb air The fine dust and particles in the product will affect the yield of the product (if the static electricity is greater than 500 volts, it will adsorb 0.05 fine particles).
4. Electrostatic material is excessively sparked on the surface of the material, which can cause electric breakdown of the surface of the material, resulting in scrapping or damage of the material and even fire.
(c) Misunderstanding of static electricity
1. Most of the static eliminators are purchased and used by non-professionals from the SEG market or non-professional traders. In addition to the inefficient electrostatics, the high-voltage generators in the long-term use are depleted, and some static electricity is eliminated. Good product.
2, the operator does not have a good maintenance and maintenance of static eliminator 3, from the unilateral to eliminate rather than the overall solution of the backlight industry, the micro dust dander solution
(A) The source of micro dust shavings
1. Dust on the surface of the material (pollution of the raw material from the die-cutting plant to the backlight plant during the turn)
2. The static electricity generated during slitting, die-cutting, and laminating will adsorb the fine dust in the air. 3. The cuttings that are cut out during die-cutting. (II) Solutions
1. Select an appropriate electrostatic precipitator (sheets and coils to remove fine dust on the surface of the film). Refer to the technical parameters. 2. Control during sheet wrapping or coil winding to prevent secondary pollution (site technical support)
