Step 4: spinning tube cavity, water circulating pump and the autolyzed alloy bunch of high-purity iron family element of not being bent is closed Object aqueous solution forms closed cycle;
Step 5: the spinneret that is not bent is electrolysed, and open the water circulating pump.
Further, the step 2 includes carrying out oil removing to the spinneret that is not bent by alkaline solution, then pass through Tap water cleans the spinneret that is not bent.
Further, the alkaline solution presses NaOH, Na2CO3And Na3PO4Concentration be respectively 50g/L, 30g/L with And the mode of 30g/L configures.
Further, step 1 specifically include to it is described be not bent spinneret along axial 3/5 part of centre, after bending The concave side position of spinneret radially, stays the hole of a 2~6mm of diameter every 3~10cm.
Further, step 5 specifically include by it is described be not bent spinneret be placed on mass percent be 5%~30% The cathode of aqueous sodium carbonate be electrolysed;
After 5-10 minutes to be energised, the water circulating pump is opened;The water circulating pump and electricity are closed after continuing 2 hours Source.
Further, step 3 specifically includes: being that 1~10% sulfuric acid solution spits described be not bent by mass percent Fiber tube acid-wash activation.
The present invention by sprawled in spinning tube outer surface inner surface hydrogen and thus caused by low temperature iron group autolyzed conjunction Golden cluster compound hydrogenates fast deposition;Using the autolyzed alloy coated layer of iron family element, realize that spinning pipe internal surface high temperature is tough Change, achievees the purpose that improve its service life.
Specific embodiment
The present invention is described in further detail With reference to embodiment.
The invention proposes a kind of low temperature fast deposition process of table in spinneret, to the not curved of not yet progress bending process Bent spinneret is pre-processed, to improve its high temperature obdurability.The present invention carries out as follows:
S101, it will not be bent spinneret along axial 3/5 part of centre, the concave side portion of spinneret radially after bending Position, stays the hole of a 2~6mm of diameter every 3~10cm;
It is compound to obtain using paraffin Seal treatment, then by fine needle or the processing of thin stick through-hole when drilled hole is excessive The aperture that diameter requires;
The purpose of punching is to prevent not being bent spinning tube cavity in subsequent step and the different aqueous solutions of outer surface are obvious Leakage mixing, but hydrogen sprawling from spinning tube outer surface inner surface when electrolysis processing is not influenced;
S102, it will not be bent spinneret and be connected to water circulating pump, by alkaline solution oil removing, wherein alkaline solution is pressed NaOH、Na2CO3And Na3PO4Concentration be respectively that the mode of 50g/L, 30g/L and 30g/L configures;Pass through tap water again The spinneret that is not bent is cleaned;
S103, the spinneret that is not bent is followed for 1~10% sulfuric acid solution with water circulating pump and mass percent Naphthenic acid is washed to be activated;
S104, the autolyzed alloy cluster compound of high-purity iron family element and water are matched with molar percentage 0.2~1.5:1 ratio It is set to aqueous solution, putting the autolyzed alloy cluster compound aqueous solution of high-purity iron family element into length is the poly- of 1m*0.5m*0.5m In tetrafluoroethene slot;Spinneret it is not bent water circulating pump, the autolyzed alloy cluster compound aqueous solution of high-purity iron family element and again Inner cavity form closed cycle;Paying attention to, which there is no, need to open water circulating pump;
Specifically, it is not bent spinneret both ends and installs PVC material flange, aperture size size is interior with selected spinneret Diameter is the same.Two end flanges of spinneret all connect corresponding plastic tube, and are fastened with suitable lead screw.Two plastic tube other ends All fasten with the connection of small-sized cycle water pump interface, and small-sized circulating water pump submerges to be placed in configured cluster compound molten In the polytetrafluoroethylene (PTFE) slot of liquid, to realize that the closed cycle of cluster compound aqueous solution, guarantee are not bent the certain freedom of spinneret Degree;
S105 is while retaining the closed cycle of S104, the sodium carbonate that will not be bent spinneret and be placed on 5%~30% It is electrolysed in aqueous solution, the 1/4 of spinneret specific length and the polytetrafluoroethylene (PTFE) slot of height 0.5m is taken using long 1m, width For electrolytic cell, and it is not bent spinneret and is placed in cathode end side, anode then uses length 1m, wall thickness 5mm and internal diameter for 10mm Q235 steel pipe.
Wherein, not being bent spinneret can move freely along the width direction of polytetrafluoroethylene (PTFE) slot electrolytic cell, so as in it Surface needs the intermediate portions strengthened to be among aqueous sodium carbonate cladding;
In S105, preferably to be not bent spinneret carry out concussion rotation improve reaction effect.
Voltage 0-240V regulated power supply, voltage 120-220V are used when electrolysis, current density is set as 20~200A/ cm2, operation temperature room temperature, energization closes circulating pump and regulated power supply after opening water circulating pump, then 2 hours after 5-10 minutes, heavy Product finishes.
