2. Breeding small animals such as chickens, ducks and geese, enclosure protection for fruit trees and gardens, and protection for medium-sized breeding, it is recommended that you choose products with a wire diameter of 2.3mm-2.5mm.

Hexagonal mesh is made of galvanized iron wire woven by automatic mesh machine, mesh into regular hexagonal, mesh standard, beautiful, mesh size can be customized according to customer requirements, usually 27mm,20mm, 13mm, wire diameter from 0.40mm to 1.20mm, to meet the requirements of different customers.

Galvanized iron wire has good anti-corrosion and anti-rust ability, so it can be prevented from being used in some outdoor guardrail or fence, especially on handicrafts, handicrafts are also of great use, galvanized iron wire, the surface is not easy to rust and oxidation. Now many hardware manufacturers produce iron wire, and iron wire is very easy to rust, if you need to use in outdoor or humid places, generally customers will require the use of galvanized iron wire equipment to give the wire a layer of zinc, the thickness can be determined according to user requirements.

The breeding galvanized electric welding net is still in the construction project and has been well used. It is because of such a network, so now in the construction project, can save more time and effort. Not only in this industry, such as breeding and breeding in nursery stock and supermarket shelves, have started to use such nets, to meet the needs of the industry, and can also well help people in their jobs.

Appellation: Hook fence is a variety of guardrail. The diameter of the opposite side of each mesh is generally 6.5cm-14cm. The thickness of the wire used is generally from 3.5mm to 6mm. Wire material is generally Q235 low carbon wire. The wire is welded by gimmick into decorative hook mesh black. The general size of the net is 1.5 meters X4 meters, 2 meters X4 meters, 2 meters X3 meters. The general surface treatment is cold (electric) galvanized treatment. There are also hot dip galvanizing, dip plastic, spray plastic. But overall, 99 percent is cold (electric) galvanized.

Why all of a sudden is there so much interest in the safety of Titanium Dioxide?

Researchers from France and Luxembourg gave E171 (the much more food friendly name for Titanium Dioxide) in Europe and the United States, to lab rats in their drinking water for 100 days.

Of those rats, 40 per cent of the exposed rodents developed “preneoplastic lesions” or precancerous growths. The Titanium Dioxide also inhibited the immune systems of the rats and “accelerated” the growth of the lesions. France’s INRA agricultural research institute, which took part in the study, said in a statement.“These results demonstrate a role in initiating and promoting the early stages of colorectal cancer formation,” though it said no conclusion could be drawn about later phases of cancer, or of any danger to humans……….(not till they test it on us!!)

The results of the study were published in the Nature journal Scientific Reports.

The paints and coatings industry reduced their offtakes which coupled with the drop in the crude oil prices and availability of cheaper imports from the Asian market led to the fall in titanium dioxide prices. The demand decreased significantly in the fourth quarter along with the slow manufacturing due to high inflation rates keeping the price trends of the commodity in the negative zone.

At the present JECFA meeting, the committee considered additional toxicological studies relevant to the safety assessment of the chemical that investigated its toxicokinetics, acute toxicity, short-term toxicity, long-term toxicity and carcinogenicity, genotoxicity, and reproductive and developmental toxicity, as well as special studies addressing its short-term initiation/promotion potential for colon cancer. The experts acknowledged that a large number of toxicological studies have been conducted using test materials, including nanoparticles, having size distributions and physico-chemical properties not comparable to real-world uses of titanium dioxide as a food additive. The studies on non-representative materials were evaluated by JECFA, but the committee concluded that such studies are not relevant to the safety assessment of the additive.

Despite a bullish trends ruling the market for the bulk of the period, the North American market had mixed sentiments in the fourth quarter of 2021. This was mostly due to the adequate pushback from the supply-demand imbalance, which was further compounded by rising natural gas prices, which had taken a proper toll on the future production of numerous minerals, including titanium dioxide. An increase in COVID instances had prompted concerns in ore feedstock. As a result, during the fourth quarter of 2021, the FD UGSC (USA) quarterly average negotiations for the chemical CP Rutile Grade were finalised at USD 4434 per tonne.

In a 2022 study published in the Journal of Hazardous Materials, scientists wanted to examine the effects of titanium dioxide as a food additive on atherosclerosis in mice. (Atherosclerosis refers to a hardening of the arteries.) Researchers fed mice 40 mg/kg of the food additive every day for 4 months, and found that it not only altered gut microbiota but also led to a significantly increased atherosclerotic lesion area, especially in animals that consumed a high-choline western diet (HCD).
