Description
Technical field
The invention belongs to water purification fields, and in particular to a kind of production of the fore filter strainer with polytetrafluorethylecoatings coatings
Method.
Background technique
Water purifier is also water purifier, water purifier, is to carry out depth-type filtration, purification to water quality by the requirement to water
The water treatment facilities of processing.Its technological core is the filter membrane in filter element device, and major technique derives from ultrafiltration membrane and RO at present
Two kinds of reverse osmosis membrane.Water purifier can effectively filter out iron rust in water, sandstone, chlorine residue in colloid and absorption water, odor, it is heterochromatic,
The chemical agents such as pesticide.The impurity such as bacterium, germ, toxin, the heavy metal in water can be effectively removed.
Water purifier fore filter working principle is physics sieving, and filter core is mainly stainless steel filtering net, and main interceptor is
The large particulate matters such as silt, iron rust, algae protect the watering equipment in water route and family, are the first line of defences of full room water.No
Rust steel strainer precision key effect is played to the effect of filtering: precision is too low, filtering it is ineffective, do not have protection make
With；Filtering accuracy is excessively high, and filter core be easy to cause dirty stifled needs often cleaning.Stainless steel filtering net because being immersed in water for a long time simultaneously
In, in addition the iron rust of interception, silting, easily generation electrochemical corrosion, influence service life.
It can only be user's periodic cleaning or more in view of the above-mentioned problems, at present on the market there are no effective solution method
Strainer is changed, brings unnecessary trouble and loss to user.
Summary of the invention
The production method of the purpose of the present invention is to provide a kind of fore filter strainer with polytetrafluorethylecoatings coatings is used
In solving the problems, such as that existing strainer service life is short, extend cleaning and the replacement cycle of strainer, extends filter to reach
Service life.
To achieve the above object, the technical solution used in the present invention is:
A kind of production method of the fore filter strainer with polytetrafluorethylecoatings coatings, it is characterised in that including following step
It is rapid:
S1, polytetrafluorethylecoatings coatings solution is prepared:
S101, by polyflon by 1~10h of heat treatment at a temperature of 300~420 DEG C, obtain polytetrafluoroethyl-ne
Alkene lotion；
S102, ptfe emulsion is added to absolute ethanol again, ultrasonic disperse 45min, obtaining concentration is 0.1g/mL
Polytetrafluorethylecoatings coatings solution；
S2, polytetrafluorethylecoatings coatings solution is coated uniformly on screen surface.
Further, the partial size of the polyflon is 0.1 μm -10 μm.
Further, polytetrafluorethylecoatings coatings method for solution coating described in the step S2 is to brush or spray.
Further, polytetrafluorethylecoatings coatings method for solution coating described in the step S2 is dip-coating, comprising: by strainer
It is put into polytetrafluorethylecoatings coatings solution, takes out after placing 10S, then bake 10-20S at a temperature of 300~420 DEG C, finally exist
Molten condition chilling, to form the polytetrafluorethylecoatings coatings of hard on strainer.
Further, the chilling refer to the molten condition from polytetrafluorethylecoatings coatings with 50~100 DEG C/sec of speed into
Capable cooling.
Further, the strainer is stainless steel filtering net or ceramic post sintering strainer.
Further, the strainer filtering precision is in 50-600 mesh.
The invention has the benefit that the present invention extends strainer for solving the problems, such as that existing strainer service life is short
Cleaning and replacement cycle, to reach the service life for extending filter.The band polytetrafluorethylecoatings coatings manufactured through the invention
Fore filter strainer, surface smoothness is high, corrosion-resistant, wear-resisting, resistance to acid and alkali, folding, anti-oxidant, enhances the hydrophobic of strainer
Property, so as to improve cleaning effect, shorten scavenging period and period, extends the service life of strainer.
Detailed description of the invention
Fig. 1 is fore filter strainer schematic diagram.
Specific embodiment
For a better understanding of the present invention, technical solution of the present invention is done further below with reference to embodiment and attached drawing
Explanation.
A kind of production method of the fore filter strainer with polytetrafluorethylecoatings coatings, comprising the following steps:
S1, polytetrafluorethylecoatings coatings solution is prepared:
S101, by partial size be 0.1 μm -10 μm polyflon by the heat treatment 1 at a temperature of 300~420 DEG C
~10h, obtains ptfe emulsion；
S102, ptfe emulsion is added to absolute ethanol again, ultrasonic disperse 45min, obtaining concentration is 0.1g/mL
Polytetrafluorethylecoatings coatings solution；
S2, by the uniform dip-coating of polytetrafluorethylecoatings coatings solution (or brush or spraying) in screen surface, comprising: will
Strainer is put into polytetrafluorethylecoatings coatings solution, is taken out after placing 10S, then is baked 10-20S at a temperature of 300~420 DEG C and made
Polytetrafluorethylecoatings coatings reach molten condition, finally in the molten condition chilling of polytetrafluorethylecoatings coatings, thus the shape on strainer
At the polytetrafluorethylecoatings coatings of hard.The chilling refers to the molten condition from polytetrafluorethylecoatings coatings with 50~100 DEG C/sec
The cooling that speed carries out prevents strainer ontology from annealing and losing rigidity.Wherein strainer is stainless steel filtering net or ceramic post sintering strainer
Etc. high temperature resistant strainer capable of washing, strainer filtering precision is in 50-600 mesh.
The strainer of this method production includes the stainless steel filtering net with polytetrafluorethylecoatings coatings and ceramic post sintering strainer, and common
The comparison surface of stainless steel filtering net or ceramic post sintering strainer is highly polished, corrosion-resistant, wear-resisting, resistance to acid and alkali, folding, it is anti-oxidant,
The clear advantages such as hydrophobicity is good.
Described above is only Application Example of the invention, cannot limit the right model of the present invention with this certainly
It encloses, therefore according to equivalence changes made by scope of the present invention patent, still belongs to protection scope of the present invention.
