Car purifiers are also called car purifiers or car air purifiers, usually composed of high-voltage generating circuit negative ion generators, micro fans, air filters and other systems. Its working principle is as follows: the micro-fan (also known as the ventilator) in the machine circulates the indoor air, and the polluted air passes through the air filter (filtered twice) in the machine to remove or adsorb various pollutants.

Then it passes through the negative ion generator installed at the air outlet (the high voltage in the negative ion generator generates DC negative high voltage during work), which continuously ionizes the air to produce a large number of negative ions, which are sent out by the micro fan to form a negative ion air flow. To achieve the purpose of cleaning and purifying the air. There are also vehicle-mounted purifiers with solar panels, which can run for a long time without being connected to electricity, and some of the latest technologies for decontamination in the vehicle, such as UFCO technology!

There are many models of car air purifiers on the market, mainly composed of five purification elements, and their general functions are: load a small amount of precious metals on metal oxides to obtain high formaldehyde oxidation activity at room temperature. The catalyst is composed of metal oxide as the main body, and noble metal components are supported on the metal oxide. It is characterized in that the aforementioned metal oxide component can be at least one of the following metal oxide groups, and the aforementioned noble metal component can be at least one of the following noble metal groups.

Metal oxides: aluminum oxide, nickel oxide, manganese dioxide, silicon dioxide, iron oxide, precious metal group: platinum, ruthenium, gold, rhodium, palladium. The catalyst of the present invention is composed of common metal oxides and a small amount of precious metals, and can be effectively applied to the catalytic oxidation of formaldehyde under room temperature conditions. The catalyst of the present invention has high catalytic activity and long duration. The catalyst of the present invention has a conversion rate of formaldehyde up to 100% within the effective working time range.

Introduce the transportation precautions of high-efficiency disinfectant

Disinfectants are often referred to as "chemical disinfectants". High-efficiency disinfectants can kill all bacterial multiplication bodies (including mycobacteria), viruses, fungi and their spores, etc., and also have a certain killing effect on bacterial spores. High-level disinfection requirements, including chlorine-containing disinfectants, ozone, methyl hydantoin compounds, double-chain quaternary ammonium salts, etc.
