Abstract
The application that the invention discloses polytetrafluoroethylene (PTFE) in kitchen ventilator, the especially application using polytetrafluoroethylene (PTFE) as non-sticking lining on kitchen ventilator can efficiently solve the practical difficulty for depositing and being difficult to clean in kitchen ventilator surface and oil contaminant.Using polytetrafluoroethylene (PTFE) as non-sticking lining, the resistance to corrosion of kitchen ventilator can be improved.It is easy to clean due to polytetrafluoroethylene (PTFE) feature non-stick, service life of equipment is improved, the dosage of detergent and water body is greatly saved, reduces the discharge of sewage, reduces the cost of sewage treatment, has reached energy-saving and environment-friendly effect.
Description
Technical field
The invention belongs to non-sticking lining technical fields, and in particular to application of the polytetrafluoroethylene (PTFE) in kitchen ventilator.
Background technique
The smoke exhaust ventilator articles indispensable as kitchen, bring great convenience to us, but it clear simultaneously
Clean is also a problem.Cleaning smoke extractor needs to be split cleaning, and greasy dirt above is difficult to clean up, and frequently tears open
It unloads, using various detergents, can undoubtedly shorten the service life of smoke exhaust ventilator.
Polytetrafluoroethylene (PTFE) (Polytetrafluoroethylene, PTFE) " King ", is polymerize by tetrafluoroethylene monomer
Made of polymer, be a kind of transparent or opaque wax similar to PE, density 2.29/cm3, water absorption rate is less than
0.01%.Polytetrafluoroethylene (PTFE) have excellent chemical stability, corrosion resistance, sealing property, high lubrication, non-stickiness, electrical insulation and
Good ageing resistance, have become at present production film one of important materials, purposes be related to aerospace, petrochemical industry,
The industrial departments such as machinery, electronics, building, light textile, become many key technologies of solution and raising production technology level is indispensable
Material.
Summary of the invention
Aiming at the deficiencies in the prior art, the present invention provides the new application of polytetrafluoroethylene (PTFE).
New application provided by the present invention is specially application of the polytetrafluoroethylene (PTFE) in kitchen ventilator,
More specifically, application of the polytetrafluoroethylene (PTFE) as non-sticking lining in kitchen ventilator.
Compared with prior art, the invention has the advantages that: can efficiently solve in kitchen ventilator surface and oil contaminant deposition and hardly possible
With the practical difficulty of cleaning.Using polytetrafluoroethylene (PTFE) as non-sticking lining, the resistance to corrosion of kitchen ventilator can be improved.Due to poly-
Tetrafluoroethene feature non-stick, it is easy to clean, service life of equipment is improved, the dosage of detergent and water body is greatly saved,
The discharge for reducing sewage reduces the cost of sewage treatment, has reached energy-saving and environment-friendly effect.
Specific embodiment
The present invention is described below with reference to specific embodiments.It will be appreciated by those skilled in the art that these embodiments are only
For illustrating the present invention, do not limit the scope of the invention in any way.
When manufacturing kitchen ventilator, in coating one layer of polytetrafluorethylecoatings coatings on metal body, the thickness of the coat can be with
At 100 ~ 200 microns.
In order to make metal body surface layer obtain enough surface adhesion forces, metal can be made using method physically or chemically
Body cleaning (removes whole greases surfaces to be coated first, dissolves grease using organic solvent, and be heated up to about 400 without attachment
DEG C it is made to volatilize completely.Then, metal body is cleaned using the mechanical system of blasting treatment, and keeps its surface crude；It can lead to
Crossing using the mode of bonding additives (priming paint) improves coating with the binding ability on metal body surface layer).
The coating method of polytetrafluorethylecoatings coatings can be using one of following methods:
One, powder coating:
The method of powder coating processing is a kind of dry-type processing, and coating material used herein is ultrafine solid particle
Form.Using this coating process, the Divergent Phenomenon occurred when adhering to using solvent and subsequent coating is avoided；Processing
Micro mist shape coating granule is attached on metal body using appropriate method.Process specifically includes that
(1) powder sprays: powdery particle is blown out from trap by compressed air, in the way that it leads to spray tip, there is one
The region of section static electrification.Due to particle band like charges, they are mutually exclusive in its flight path, and form uniformity
Cloud form it is spraying.Metal body ground connection to be sprayed, forms the area of a static electrification whereby, between spray gun and metal body
Domain.Powdery particle is attracted by metal body, and attached to it.
(2) powder melts: in coating technology, pyrolytic coating and low-temp. spraying are coated with the difference of principle.Such as use high temperature
Spraying, the temperature of substrate are higher than the melting temperature of powder body material, and powdery particle is overlying on thereon.Process of the micro mist in spraying in this way
In just it is molten.This processing method of low-temperature spray is then the melting temperature that base material temperature is lower than powder body material.Then in baker
In melted.
Two, dispersion coating:
The processing method of dispersion coating be make coating material be evenly distributed in solvent formed dispersion liquid (solid matter is mixed in
In liquid) a kind of wet processing.This mixture is atomized and is sprayed at metal body surface by pressure-air, specifically includes that
(1) dispersion coating sprays: spraying coating material must uniformity.Coating layer thickness depends on the coating system used；It applies
The variation of thickness degree micron may be differed from 100 to 200；
(2) dry: to heat wet coating in baker, temperature control is at 100 DEG C hereinafter, until most solvent has steamed
Hair；
(3) it is sintered: metal body is heated to a higher temperature, until an irreversible reaction occurs: coating material
Melting forms reticular structure with bonding additives.
Certainly, it is also not excluded for other coating methods, to form polytetrafluorethylecoatings coatings on metal body surface.
Although invention has been described above, but the invention is not limited in above-mentioned embodiment, on
The specific embodiment stated is only schematical, rather than restrictive, and those skilled in the art are of the invention
Under enlightenment, without deviating from the spirit of the invention, many variations can also be made, these belong to protection of the invention it
It is interior.
