3) it then carries out spraying for the second time and third time sprays, the process and first time of spraying for the second time and third time spraying spray
Process it is identical, third time spray after complete.
The group of the molybdenum disulfide slurry becomes ultra-fine molybdenum disulfide, adhesive, deionized water, and ultra-fine molybdenum disulfide glues
Mixture, deionized water mass ratio be 1:0.2-0.8:1-5.
The granularity of the ultra-fine molybdenum disulfide is 0.8-5 microns, and described adhesive is the polymerization of perfluoro capryl methyl acrylate
Object, perfluoro capryl X 4460 or perfluoro capryl sodium acrylate polymer.
The material of the reaction kettle autoclave body is steel.
Drying temperature is 105-150 DEG C in the step 2.
Anti-corrosion type reaction kettle is further preferred:
The autoclave body is fixed on horizontal plane by support, and is set with collet on autoclave body outer wall.
The collet top is provided with water inlet pipe, and collet bottom end side is provided with outlet pipe, described in the collet inner close fitting
Autoclave body outer wall is provided with infrared ray heating tube.
The autoclave body top is provided with kettle cover, and a manhole, two mirror mouths and more are circumferentially distributed on the kettle cover
A feed opening, described two mirror mouths are symmetrical arranged, and temperature-measuring port, setting in temperature-measuring port are provided on the position at kettle cover edge
There is thermometer, which is vertically arranged and protrudes into the autoclave body middle and lower part.
The agitating device is made of agitating shaft with the agitating paddle for being set to the agitating shaft lower end, and the agitating shaft top is worn
Out the kettle cover and connect on the drive means.
The driving device includes driving motor, and the driving motor is arranged in the kettle cover top by sealing sleeve pipe
The heart, and driving motor output end is arranged downward and is fixedly connected by shaft coupling with the agitating shaft.
In the above-mentioned technical solutions, the autoclave body bottom center is provided with discharge gate.
Compared with prior art, the method have the benefit that:
1, thinking of the invention is ingenious, has changed the thinking that molybdenum disulfide is commonly used to lubricant, attempt using molybdenum disulfide as
A kind of anti-corrosion material, using special process molybdenum disulfide is firmly attached to by suitable adhesive compounding needs
On the inner wall for wanting corrosion-resistant consersion unit, the inner wall of such consersion unit can high temperature resistant, acid corrosion-resistant, also being capable of hydrogen resistant fluorine
