What is HYDROFLUORIC ACID?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is HYDROFLUORIC ACID which has developed particularly rapidly in recent years. Do you know about HYDROFLUORIC ACID?
- The official answer: Hydrofluoric Acid is an aqueous solution of hydrogen fluoride gas, a clear, colorless, fuming, corrosive liquid with a pungent odor. Hydrofluoric acid is a weak acid that is corrosive and can corrode metals, glass, and silicon-containing objects. Inhalation of vapors or contact with the skin can cause burns that are difficult to heal. Laboratories generally use fluorite (the main component is calcium fluoride) and concentrated sulfuric acid to prepare, which need to be sealed in plastic bottles and stored in a cool place.
What’s the application of HYDROFLUORIC ACID?
- Due to hydrofluoric acid’s ability to dissolve oxides, it plays an important role in the purification of aluminum and uranium. Hydrofluoric acid is also used to etch glass, which can engrave patterns, label scales and text; The semiconductor industry uses it to remove oxides from the silicon surface, it can be used as a catalyst for the alkylation of isobutane and n-butene in refineries, and hydrofluoric acid is also used in the “acid immersion” process to remove oxygenated impurities from the surface of stainless steel. Hydrofluoric acid is also used in the synthesis of a variety of fluorinated organic compounds, such as Teflon (polytetrafluoroethylene) and refrigerants such as Freon. [1]
- Both hydrofluoric acid and molten sodium hydroxide can be used for the removal of glass cladding layers on the surface of microfilaments, the time for hydrofluoric acid to remove glass cladding layers with a thickness of 10 μm at room temperature is about 150s, and the time to melt sodium hydroxide is about 10 s; The composition and structure of glass are important factors affecting the corrosion resistance of glass-coated pure copper microfilaments. Glass-coated pure copper microfilaments were prepared by melt spinning method, the removal of glass clad layer on the surface of microfilaments was studied, the corrosion behavior of microfilaments in hydrofluoric acid and molten sodium hydroxide was evaluated, the corrosion resistance of glass-coated pure copper microfilaments in strong acids and strong alkalis was analyzed, and the corrosion mechanism was discussed.

WHY THEY SAY TO US
Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.
In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!
Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
Sincere Chemical team visited our USA factory in the year of 2017. We think highly of cooperation with them. We thanked you for the past excellent orders and best product quality.
