Read MoreThe common thorn rope is double strand thorn rope, models are 2.0*2.0mm, 2.25*2.25mm, 2.7*2.25mm three, and are galvanized thorn rope (plastic coated thorn rope is rarely used), the thorn distance (that is, the distance between winding wire) is generally 14 cm. Let’s take a look at what these models mean:

concrete pin nailsWhen using these two products, it is obvious that there is a gap between them. By pulling or bending the wire, it is often difficult to restore the original, for example, if the same place is repeatedly bent, it will be found that it has broken, and the cold drawing wire will not. Cold drawing wire compared with iron wire, its hardness, tensile resistance, bending ability is greatly enhanced, suitable for building materials.

Other scientists, however, have called into question the experimental designs of such studies, citing inconsistent results specifically in studies used to test DNA damage.
Genotoxicity refers to the ability of a chemical substance to damage DNA , the genetic material of cells. As genotoxicity may lead to carcinogenic effects, it is essential to assess the potential genotoxic effect of a substance to conclude on its safety.
Nanotoxicology “focuses on determining the adverse effects of nanomaterials on human health and the environment.”
On the other hand, titanium dioxide is a synthetic mineral that is produced through a chemical reaction involving the mineral ilmenite or rutile. It is used in industries such as cosmetics, paint, and sunscreen as a whitening agent and pigment. The manufacturing process of titanium dioxide involves extracting the mineral from ores, purifying it through chemical processes, and then grinding it into a fine powder.
Bluescope Steel now specifically mention sunscreen & titanium dioxide use in their warranty so they no longer have to pay out for the damage caused by a little bit of transferred sunscreen residue.
About Titanium Dioxide. Titanium Dioxide, a white crystalline powder, represents the natural oxide of titanium, with its primary occurrence observed specifically in rutile ores. This titanium compound holds remarkable significance in various technological realms, functioning as a commodity chemical extensively harnessed across diverse industries. In actuality, a substantial majority of titanium ores undergo processing procedures to yield Titanium Dioxide, consequently establishing its unrivaled status as the most extensively utilized titanium-based substance on a global scale.
Does It Cause Cancer?
The Sydney Morning Herald reported on the finding of nano particles in our food supply here in Australia, despite no testing every carried out on the safety of these products by our food safety body.
Following a request for assessment in 2020 by the EU, the European Food Safety Authority (EFSA) assessed E171, particularly for its genotoxicity. In 2022, the agency deemed the food additive no longer safe for use.
