Quality Assurance :
We have our own testing lab and advanced and complete inspection equipment, which can ensure the quality.
Dihua glass is a borosilicate glass type 3.3 as specified in international standard ISO 3585,whose chemical resistance of glass is more extensive than that of all other known materials.Borosilicate glass is highly resistant to water,acids,salt solution,organic substances and halogens such as chlorince and bromine.It also has relatively good resistance to alkaline solutions.Only hydrofluoric acid,concentrated phosphoric acid and strong alkaline solution cause appreciable surface removal of the glass at higher temperature.This kind of glass is made from natural raw materials(sand,calcium carbonate and sodium carbonate) and it doesn’t contain any materials which could be released and constitute a hazard to man or the environment .The glass can be reused several times and disposed of without difficulties.
