2, the production and installation is simple and fast, the use of patented friction connection or special connection accessories for installation, greatly improve the installation efficiency.

The quality of hot-dip galvanized barbed wire is only in the surface of the wire attached to the galvanized layer, and with the reason of the chemical reaction, the surface of the zinc layer will gradually lose its role because of the oxidation reaction, this situation is more prominent in humid areas. And because after all, the steel wire will rust, so the quality of hot-dip galvanized barbed wire is certainly not up to the level of stainless steel barbed wire.

Arrived in other ways can’t end effect of the inclination of hook flower network structure in essence is void, water permeability, the natural effect of groundwater and filtering effect has a strong inclusive, suspended in the water content and silt accumulation in fill in crevices, applied to mountain protection, is conducive to the growth of natural plant, beautify the grass spraying to arrive late his curing effect, Gradually restoring the original ecological environment is a perfect connection between beautification and protection.

Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.

Although the evidence for general toxic effects was not conclusive, on the basis of the new data and strengthened methods we could not rule out a concern for genotoxicity and consequently we could not establish a safe level for daily intake of the food additive, commented Matthew Wright, member of the EFSA's Food Additives and Flavourings Panel in a press statement.

Titanium dioxide used for adhesive applications should contain an inorganic coating to control polarity, improve its ease of dispersion, and improve its weather resistance. The inorganic coating (zirconium dioxide, silica, alumina) is applied in the aqueous slurry by precipitation of one or more hydrated metal oxides and by neutralization of acidic and alkaline compounds.
