The surface of alluvium before hot dip galvanizing of orchard special electric galvanized shaft wire can partially remove the surface film layer, surface impurity and other shortcomings according to the basic technology to find and solve; Excessive foam is caused by soap and soapable surface active substances such as human fat into the tank. A moderate rate of foam production would be fine. There are many fine homogeneous particles in the tank, can stabilize the foam layer, with activated carbon mat to remove surface active substances. Or make the bubble unstable according to overworry, these are all reasonable countermeasures; Other strategies should also be used to reduce the amount of surface-active substances introduced. The introduction of organic matter can make the electroplating process speed drop sharply. Although the secret recipe of organic chemistry is beneficial to the high accumulation rate, the thickness of the coating can not meet the requirements after the organic matter is brought in, so the activated carbon can be used to solve the tank.

Hexagonal cage has a wide range of applications, with the progress of science and technology, has been extended to the major hydraulic, civil engineering. Geotechnical engineering and other projects. In hydraulic hexagonal cage in river construction from closed utility, think appropriate and the use of hexagonal cage to fill stone, fixed river, can be used to avoid river erosion brought water and soil loss. In civil engineering projects, hexagonal cage that is suitable and the use of similar particle size volume particles to fill, mesh wall is formed between the cage, which is the stone cage retaining wall.
