Abstract

The invention discloses an online film coating device for float glass. The online film coating device comprises a suspension beam, a film coater body, gas inflow units and gas exhaust units, wherein the film coater body is mounted on the suspension beam; and a graphite plate is arranged on the bottom surface of the film coater body; the gas inflow units and the gas exhaust units are arranged alternately. Each gas inflow unit comprises a gas inflow pipe and a gas inflow device, wherein the gas inflow pipe has a smaller upper part and a larger lower part and passes through the graphite plate and coater body synchronously; the gas inflow device is arranged at the top of the gas inflow pipe; and the gas inflow pipe is provided with spiral channels. Each gas exhaust unit comprises a gas exhaust pipe and a gas exhaust device, wherein the gas exhaust pipe has a smaller upper part and a larger lower part and passes through the graphite plate and coater body synchronously; the gas exhaust device is arranged at the top of the gas exhaust pipe; and the gas exhaust pipe is provided with spiral channels. According to the online film coating device for the float glass, Reynolds number can be flexibly controlled; the gas flow is kept stably; the degree of uniformity and the yield ratio of film coating are improved; and the mounting cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of coating, in particular to an online coating device for float glass. Background technique [0002] Coated glass is coated with one or more layers of metal, alloy or metal compound films on the surface of the glass to change the optical properties of the glass to meet certain requirements. Coating processes include vacuum magnetron sputtering, vacuum evaporation, chemical vapor deposition, and sol-gel methods. On-line coating is to use advanced coating technology (CVD) to directly coat one or more layers of nano-particle-sized metals, alloys or metal oxides on the surface of high-temperature, clean and high-quality float glass substrates on the float glass production line. Thin films are used to modify the surface of the glass to endow the glass with a variety of special functions, such as sunlight control function, low radiation function, self-cleaning function, transparent and conductive function, etc., ...
