To state the composition, nature and development status of organic materials (light functional materials) In order to find out the chemical composition and composition of luminous powder,The first thing we thought about was the glow,The principle of light emission in vivo has the following series of processes.And that's why it continues to shine,And the reason for the flash of light,It is worth noting that,The green light emitted by the green light is a \ 'Cold Light \',The conversion rate of the results reached 97%.Secondly,We noticed the glow of glowing plastic,Luminous plastics are mainly mixed with some radioactive substances in ordinary plastics,Such as 14C, 35Sr, 90Sr and Na, Th and light-emitting materials, such as zinc sulfide and CaS, under the irradiation of radiation light,Visible light (Cold Light) is emitted by excitation ).The chemical composition of the fluorescent powder is composed of fuzzy silicate, tungsten salt,The single element Ba and Sr finally deepene
What is the role of the front water purification filter? The front water purification filter is an important part of the whole house water purification equipment.The front water purification filter is the first crude filtration equipment for the whole house water purification, which can filter large particles such as sediment, rust and so on in tap water. The front filter is generally installed at the front end of the pipe.The front water purification filter is usually a 'T' type structure. The 'one horizontal' position above is the inlet and outlet respectively at the left and right ends. The 'one vertical' position below is the cylindrical filter screen inside the body and the bottom end is the sewage outlet, which is opened and closed by a valve.The precision range of the filter screen ranges from 5-300 microns (depending on the brand ). The main removal of precipitated impurities and granular impurities greater than 5 microns such as bacteria, microbial debris, rust and sand mud from the pipeline to av
