Ventilator filtering screen coated with ceramic and manufacturing method thereof

Abstract

The present invention relates to a ventilator filtering screen coated with ceramic and a manufacturing method thereof, and especially to the ventilator filtering screen which has a material surface of the ventilator filtering screen coated with ceramic thereby not only can easily remove the deposit of the acid-decayed and deteriorated edible oil vapor for sustaining a clean state for a long time but also obtain an effect that the coating is non-combustible or hard-combustible and can restrain the generation of noxious gas when the hot vapor from fire disaster or high-temperature environment passes through the ventilator filtering screen.

Description

technical field [0001] The present invention relates to a range hood filter and a manufacturing method thereof, in particular to a range hood filter and a manufacturing method thereof having the following effects by coating the material surface of the range hood filter with a functional ceramic layer, namely (1 ) Effectively improve the detergency, so that it is easy to wash and remove the attachments of heated rancid and deteriorated edible oil vapors, so as to maintain a clean state for a long time; (2) Due to the enhanced washing resistance, frequent washing can also It will not reduce the gloss or cause the deformation, discoloration and cracking (cracking) of the filter due to scratches on the surface, and the coating film coated on the range hood will not be peeled off; (3) in case of fire Or when high-temperature hot steam passes through the filter screen of the range hood, the coating film has the effect of non-combustibility or flame retardancy, and can also inhibit t...

AI Technical Summary

Problems solved by technology

[0004] First: The range hood filter that directly bears heat of at least 80-200°C or indirectly bears heat through oil, water vapor, combustion gas, etc. on the steam will accumulate oil and combustion gas due to being attached over time. Pollutants, discoloration, decolorization, carbonization, etc., and there are problems such as the ventilation and filtering effect of the range hood filter

The pollutants attached to the filter are chemically bonded on the surface of the filter, so it is difficult to wash with detergent and brush

[0005] Second: When the filter is made of plastic, due to its disadvantages, that is, due to the low surface hardness (pencil hardness 3B ~ 2H), with frequent washing of the range hood filter, scratches will occur on the surface and reduce the luster, and it is easy to Dissolved and swelled by organic solvents such as benzene, toluene, and acetone, resulting in deformation, discoloration, and cracking (cracking) of the filter screen

Moreover, when powder coatings or organic coatings are applied to the metals, ceramics or plastics, the organic coating film and oily pollutants will not only be difficult to wash due to chemical combination, but also tend to be scratched during washing. And the phenomenon that the coating film is peeled off, therefore, the functional effect of the range hood filter is reduced
