It is very important to know the important guarantee of railway transportation, because most of the enterprises now choose the mode of transportation is railway transportation, and railway as an important means of transportation for people to go out, its safety is a social concern. At this time the blade thorn rope can play a very good practical value in various railway trunk lines.
- Electric welding net is also known as external wall insulation wire mesh, galvanized wire, galvanized electric welding net, wire mesh, row welding net, touch welding net, construction net, external wall insulation net, decorative net, wire mesh, square eye mesh, screen mesh, anti-crack mesh. Stainless steel electric welding mesh, is made of high quality stainless steel wire row welding, more acid resistance, alkali resistance, welding firm, beautiful, widely used and so on.
In the process of composite electroplating galvanized wire, the plating solution must be stirred to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. The acid activation solution in the production process can remove the corrosion products and oxide film on the surface of the low carbon steel wire without excessive corrosion on the matrix.

Now the pet cage on the market is still mainly wire cage, so the identification of wire cage mainly has the following parameters:
-
Atmospheric relative humidity At the same temperature, the percentage of atmospheric water vapor content and its vapor saturation content is called relative humidity. Below a certain relative humidity, the corrosion rate of metal antirust oil is small, while above this relative humidity, the corrosion rate increases sharply.

- Moreover, NIOSH has also delved into the emerging field of nanotechnology, where TiO2 nanoparticles find applications in sunscreens, self-cleaning surfaces, and air purification systems. These nanoparticles can have different toxicological properties than their bulk counterparts, necessitating a more nuanced approach to risk assessment These nanoparticles can have different toxicological properties than their bulk counterparts, necessitating a more nuanced approach to risk assessment

niosh titanium dioxide. NIOSH has published guidelines and hazard evaluations to address potential exposure risks and promote safe handling practices.
- titanium oxide and 2 per cent' sulphuric acidand 63 per cent water, are slowly added to a solution containing 1050 pounds of barium sulphide, held in a large cylindrical tank, provided with a rotary agitation :capable of producing rapid agitation. The mass isthus v rapidly agitated, and the 2 per cent of sulphuric acid contained in the titanium acid cake reacts with a small portion of the barium sulphide. This reaction may be represented by the following equation TiO H 80 The free sulphuric acid of the titanium acid cake is neutralized by thebarium sul-' phide solution, forming barium sulphate and hydrogen sulphide, as indicated by the above equation. As the sulphuric acid is present only in a small percentage, the major porltiion of the barium sulphide remains as suc very fine colloidal suspension. The barium sulphate produced is also very fine, and the presence of this. very fine barium sulphate in suspension, and also of the very fine colloidal titanium oxide, is believed to be the explanation of the great improvement in the properties of the finished lithopone.
Available studies in humans and postmortem analysis of tissues suggested that the oral bioavailability of titanium dioxide in humans is very low. JECFA noted that there are currently no epidemiological studies that allow any conclusions to be drawn with respect to an association between dietary exposure titanium dioxide and human health effects.

Titanium dioxide comes in the form of a white powder and is sometimes used in cosmetics to adjust a color to a lighter shade. This is also why it can produce a white cast.
③ Paper making industry: Paper making and paper products industry is the third largest application industry of titanium dioxide. Paper using titanium dioxide has good whiteness, high strength, luster, thin and smooth, and is not easy to penetrate when printing. Under the same conditions, the opacity is 10 times higher than that of paper using calcium carbonate and talc powder, and the weight can also be reduced by 15% to 30%. The amount of titanium dioxide in decorative paper accounts for 20%~40% of its raw materials, and the amount of titanium dioxide in other papers is about 1%~5%. Due to the continuous adjustment of the industrial structure of the paper products industry from 2016 to 2018, according to the data of China Paper Association, the output of China's paper products in 2019 was 72.19 million tons, a significant year-on-year increase of 29.4%, and the use of titanium dioxide increased significantly.

Toxic effects of TiO2 NPs on soil organisms
Prof. Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), wrote of the decision: “Taking into account all available scientific studies and data, the Panel concluded that titanium dioxide can no longer be considered safe as a food additive. A critical element in reaching this conclusion is that we could not exclude genotoxicity concerns after consumption of titanium dioxide particles. After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body.”
Lithopone B301, Lithopone B311 powder’s 2 main components:
As of August 7, the use of titanium dioxide in food is banned in the European Union. Europe is taking a precautionary principle approach based on findings from the European Food Safety Authority (EFSA).
