Northwest China area located at inland area belongs to High aititude, low pressure area, and long-term drought, precipitation is rare, dust storm
It is larger.These areas are also the integral base of China's water power, wind-powered electricity generation and large-scale fuels and energy, and the energy can be in the form of electric energy
The area conveying more flourishing to east economy.With the rapid development of China's economy and electric power, the continuous improvement of voltage class, more
It will be applied on transmission line of electricity and substation come more super, extra-high voltage insulator.However, " transferring electricity from the west to the east " surpasses, is extra-high
Pressure transmission line necessarily passes high altitude localities, according to the study found that being reduced with height above sea level raising or air pressure, the pollution flashover electricity of insulator
Pressure is also corresponding to be reduced, and the range of decrease is larger.Therefore, compared with plains region, the staining problem of high altitude localities will be protruded more, very
It can extremely cause the supply of electric power of east developed regions to be interrupted, influence the normal life of the normal production and the people of industry.
Anti-pollution measure workload that traditional porcelain insulator periodical power failure cleans is heavy, cost is high, far can not meet
The needs of electric power development；It is super, extra-high voltage insulator volume is big, weight weight, if continue by the way of increasing insulator creep distance come
It is antifouling, undoubtedly great difficulty is brought to the manufacture of insulator；Organic Hydrophobic Coatings are applied in insulator surface, the service life has
Limit, and do not meet northwest drought climate characteristic short of rain；Though hydrophobic silicon rubber compound insulator is widely used, and with excellent
Anti- " pollution flashover " performance, but there is also it is easy to aging, can puncture, rigidity is not high, weatherability is poor the defects of, wind-force big for dust storm
For strong the Northwest, it is difficult to ensure that the operation reliably and with long-term of power grid.

Dust-proof glaze；
(4) insulator that step (3) applies is dried under field conditions (factors)；
(5) dry coating insulation is put into heat setting stove and is hardened.
There are much relations with indoor temperature for mixing time, should be judged based on no obvious sediment or suspended matter.
Raw material order of addition changes, in solution preparation process generate the phenomenon that and final effect it is different.Only
The inorganic dust-proof glaze of the Northwest's porcelain insulator could be made according to above step.
To dust-proof glaze obtained with four glasss of detection viscosity are applied, flowed entirely in 12s, it was demonstrated that its good fluidity.
The present invention prepares the dust-proof glaze of novel inorganic, dust-proof glaze using sol-gel method in porcelain insulator surface
It can be used after being made.It is acted on using the powerful wind-force in the Northwest, the dust for being scattered in insulator surface drying is blown away, is made
Ceramic surface has excellent anti-dust performance.Compared with currently used organic antifouling hydrophobic material and other antifouling glaze, tool
There are anti-aging, antiscour, good weatherability, intensity height, long lifespan, has excellent wear-resisting, anti-dust performance.
The porcelain insulator application of inorganic water repelling anti-fouling glaze, includes the following steps：
(1) insulator surface being rotating is blown with compressed air, removes the attachments such as dust on insulator surface；
(2) pollutants such as the greasy dirt of insulator surface adherency are cleaned with isopropyl acetone solution；
(3) rotary speed is set, in the insulator surface coating being rotating the Northwest's porcelain insulator with inorganic
Dust-proof glaze；
(4) insulator that step (3) applies is dried with hot-air；
(5) dry coating insulation is put into heat setting stove and is hardened.
Coating insulation sublist face after detection hardening will produce after the qualified coating insulation subpack of detection according to insulator
Flow enters next procedure.
Indoor temperature or coating speed change, and the dust-proof effect of coating insulation changes therewith.
Compared with prior art, the present invention having the advantages that：
(1) formula is simple, and the product prepared is that inorganic high-temp hardens glaze, have anti-aging, good weatherability, intensity it is high,
The advantages that long lifespan；
(2) gained glaze is the inorganic porous membrane for having lotus leaf micron-nanometer dual structure, ceramic surface can be made to change
Property, have excellent wear-resisting, anti-dust performance；
(3) preparation method is simple, energy conservation and environmental protection；
(4) the Northwest's porcelain insulator described in not only thoroughly solves that the Northwest is super, extra-high voltage with inorganic dust-proof glaze
" pollution flashover " problem of power transmission and transformation and railway track traffic, and be widely used in new energy, automobile, ceramics, building and national defence etc.
Industrial circle has a vast market foreground.
