2. When the weather is too dry and humid, remember to blow dry the cage or move it to a place with heating to prevent dry crack damage.

Take 20cm galvanized wire for acid fog experiment, check the zinc content of galvanized wire through the balance to see whether it meets the zinc layer standard required by customers, ensure that the metal wire achieves the role of rust and corrosion prevention, and meet the service life required by customers. Galvanized iron wires must be packed in good condition, bound neatly and orderly, and bound inward to prevent scratches during transportation. The inspection standard of galvanized iron wire also includes the tensile test, which is decided according to the material of the galvanized wire order ordered by the customer, and it needs to be tested by comparing the raw material list.

Stainless STEEL HAS THE ABILITY to resist ATMOSPHERIC OXIDATION – that is, rust resistance, but also has the ability to resist corrosion in the medium containing acid, alkali, salt – corrosion resistance. However, the corrosion resistance of the steel varies with its chemical composition, additive state, service conditions and environmental media type.

That layman how to identify the amount of galvanized, can use the following three methods. Professionals told us that the surface layer of the high-zinc barbed rope would not be particularly smooth due to the zinc behind it, which could be found when comparing the two products. Although the zinc barbed wire zinc layer is thin but relatively smooth.

Zinc pot workers should be determined to do duty and responsibility. Do not leave the post without leave, always observe the change of hot plating wire galvanized layer, and according to the analysis results, master the asbestos block gap friction, how long it takes to press, replace the pressing face; Adjust the working face; Until all four faces of the asbestos block are used up, maintenance workers can continue to use the asbestos block after repair when necessary to reduce the consumption of asbestos block.

Amount: if too little titanium dioxide is added, the distance between particles is too large and there is not enough opacity, while if the titanium content is too high, the particles interfere with each other and poor efficiency is obtained.

In an early study Jani et al. administred rutile TiO₂ (500 nm) as a 0.1 ml of 2.5 % w/v suspension (12.5 mg/kg BW) to female Sprague Dawley rats, by oral gavage daily for 10 days and detected presence of particles in all the major gut associated lymphoid tissue as well as in distant organs such as the liver, spleen, lung and peritoneal tissue, but not in heart and kidney. The distribution and toxicity of nano- (25 nm, 80 nm) and submicron-sized (155 nm) TiO₂ particles were evaluated in mice administered a large, single, oral dosing (5 g/kg BW) by gavage. In the animals that were sacrificed two weeks later, ICP-MS analysis showed that the particles were retained mainly in liver, spleen, kidney, and lung tissues, indicating that they can be transported to other tissues and organs after uptake by the gastrointestinal tract. Interestingly, although an extremely high dose was administrated, no acute toxicity was observed. In groups exposed to 80 nm and 155 nm particles, histopathological changes were observed in the liver, kidney and in the brain. The biochemical serum parameters also indicated liver, kidney and cardiovascular damage and were higher in mice treated with nano-sized (25 or 80 nm) TiO₂ compared to submicron-sized (155 nm) TiO₂. However, the main weaknesses of this study are the use of extremely high single dose and insufficient characterisation of the particles.
