high quality submersible slurry pump factories

Critical to the engineering of the pump are heavy duty bearing frames and shafts, extra thick wall sections and easily replaceable wear parts. Total life cycle cost considerations are critical when specifying pumps for severe operating conditions, such as FGD service. High chrome pumps are ideal due to the corrosive pH of the slurry.

testing station in the world, and its test capacity can reach 13000m³/h. Annual output of our products is 10000

A >dredge pump is a horizontal centrifugal pump that is the heart of a dredger. It is designed to handle suspended abrasive granular materials and solids of limited size. Without a dredge pump, a stranded dredger would not be able to deliver mud.

FDA’s response

In its 2016 opinion, the ANS Panel recommended new studies be carried out to fill the gaps on possible effects on the reproductive system, which could enable them to set an Acceptable Daily Intake (ADI ). Uncertainty around the characterisation of the material used as the food additive (E 171) was also highlighted, in particular with respect to particle size and particle size distribution of titanium dioxide used as E 171.   

Although the evidence for general toxic effects was not conclusive, on the basis of the new data and strengthened methods our scientists could not rule out a concern for genotoxicity and consequently they could not establish a safe level for daily intake of TiO₂ as a food additive.

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.  

1. What is titanium dioxide?

A safety review conducted by the EFSA in 2021 assessed thousands of studies published on titanium dioxide.

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.”

Background

A 2012 study published in the journal Environmental Science & Technology noted that children are especially exposed to titanium dioxide because of the food that contains the food additive and is particularly marketed to children, including candy and cakes.

1. Lithopone is used as an inert pigment in paints, inks and cosmetics.

The most significant uncertainty identified by the EU experts was the concern that TiO₂ particles may have genotoxic effects. Genotoxicity refers to the ability of a chemical to directly damage genetic material within a cell (DNA), which may lead to cancer in certain situations. Although the experts did not conclude that TiO₂ particles in E171 are genotoxic, they could not rule out the concern that they might be.

By doing so, we achieve cost reduction, increased film strength and improved fungicidal and algaecidal properties. 

Moreover, the gravimetric method's inherent accuracy makes it a preferred choice for regulatory compliance. Many manufacturing processes are subject to stringent quality regulations, and having reliable methods for determining material composition is fundamental to meeting these standards. Accurate gravimetric analysis assists manufacturers in minimizing waste, optimizing formulations, and ensuring that end products are both effective and safe.
