Abstract
The invention relates to a using method of anhydrous disodium hydrogen phosphate as a catheter bending filler. The method comprises the following steps: step one, heating tap water to 95-100 ℃, and preserving heat; step two, putting anhydrous disodium hydrogen phosphate into hot water according to the mass ratio of 1:1, and stirring for 5-10 minutes to obtain a milky slightly viscous aqueous solution mixture; step three, pouring the milky viscous aqueous solution mixture into a catheter lumen, cooling at normal temperature and solidifying into a solid; bending and molding the conduit; heating the bent and formed conduit to 95-100 ℃ to enable the solid in the conduit cavity to be changed into viscous water solution to flow out of the conduit cavity; flushing the filler remained on the inner wall of the catheter lumen with flowing hot water for 2 minutes; step seven; and (4) putting the washed catheter into an ultrasonic washing tank, and carrying out ultrasonic washing for 5-8 minutes. The invention can complete the corresponding supporting function, shortens the processing period and has no potential safety hazard in the operation process.
Description
Technical Field
The invention relates to a filler for bending and molding an engine conduit, in particular to a using method of using anhydrous disodium hydrogen phosphate as the filler for bending the conduit.
Background
The prior art has the fillers of rosin and quartz sand for bending and molding the guide pipe of the domestic aircraft engine. The rosin filling and removing process is complex, firstly, the rosin is put into a heating furnace to be melted into a viscous liquid state, the viscous liquid state is poured into a pipe cavity to be cooled and then bent, a guide pipe with a filler is put into the heating furnace to be heated after the viscous liquid state is bent, the filler in the pipe cavity is melted and then flows out, and then the rosin remained on the inner wall of the pipe is immersed into a chemical tank liquor to be removed; the production period is as long as about 7 days, and fire hazard exists in the rosin heating process, so the process method has long period and fire hazard safety hazard. The quartz sand filler has the defects that fine sand grains are easy to remain on the inner wall of the pipe, the bending support performance is poor, and the specification range of the application conduit is limited.
Disclosure of Invention
The invention provides a using method of using anhydrous disodium hydrogen phosphate as a conduit bending filler, which can complete a corresponding supporting function, shorten the processing period and avoid potential safety hazards in the operation process.
The technical scheme of the invention is as follows:
a use method of anhydrous disodium hydrogen phosphate as a conduit bending filler comprises the following steps:
step one, heating tap water to 95-100 ℃, and preserving heat;
step two, putting anhydrous disodium hydrogen phosphate into hot water according to the mass ratio of 1:1, and stirring for 5-10 minutes to obtain a milky slightly viscous aqueous solution mixture;
step three, pouring the milky viscous aqueous solution mixture into a catheter lumen, cooling at normal temperature and solidifying into a solid;
bending and molding the conduit;
heating the bent and formed conduit to 95-100 ℃ to enable the solid in the conduit cavity to be changed into viscous water solution to flow out of the conduit cavity;
flushing the filler remained on the inner wall of the catheter lumen with flowing hot water for 2 minutes;
step seven; and (4) putting the washed catheter into an ultrasonic washing tank, and carrying out ultrasonic washing for 5-8 minutes.
The invention has the beneficial effects that: the method is suitable for bending and supporting the guide pipes with various specifications, the production period is 1-2 days, and the period is greatly shortened compared with that of rosin filling; the process method of the filler has no fire safety hidden trouble, the method for removing the filler is simple, and no residual hidden trouble exists; the problems of long period, fire hazard safety hazard, residual filler and poor supporting performance of the traditional filler are effectively solved.
Detailed Description
A use method of anhydrous disodium hydrogen phosphate as a conduit bending filler comprises the following steps:
step one, heating tap water to 98 ℃, and preserving heat;
step two, putting anhydrous disodium hydrogen phosphate into hot water according to the mass ratio of 1:1, and stirring for 8 minutes to obtain a milky slightly viscous aqueous solution mixture;
step three, pouring the milky viscous aqueous solution mixture into a catheter lumen, cooling at normal temperature and solidifying into a solid;
bending and molding the conduit;
heating the bent and formed guide pipe to 98 ℃ to enable the solid in the pipe cavity of the guide pipe to be changed into viscous water solution to flow out of the pipe cavity of the guide pipe;
flushing the filler remained on the inner wall of the catheter lumen with flowing hot water for 2 minutes;
step seven; and (4) putting the washed catheter into an ultrasonic washing tank, and carrying out ultrasonic washing for 6 minutes.
