Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the field of chemical industry, in particular to post-phosphating carried salt for a PC (polycarbonate) line and a preparation method thereof.
[ background of the invention ]
At present, borax, lime or saponification treatment is used for rust prevention after acid pickling and phosphorization of a PC wire, but a wire rod treated by the borax is easy to get damp, and when air humidity is high, water drops appear on the surface of the wire rod after the wire rod is placed for a period of time, so that the powder carrying of wire drawing powder is influenced during drawing, and the drawing efficiency and the drawing quality of the wire rod are also seriously influenced. If lime is used for treatment after phosphorization, the steel wire with too low pH value control is easy to return rust, the surface of the wire rod with too high pH value control is easy to yellow, the tank liquor is difficult to control, and the antirust effect is poor. If saponification is adopted after phosphorization, the hard sodium hyaluronate layer formed on the saponified surface is too smooth, so that the wire rod is easy to loose and slip in the stacking process, and serious safety risk exists.
It can be seen that providing an improved method is a problem that needs to be addressed in the art.
[ summary of the invention ]
The invention aims at the problems and provides a post-phosphating salt for a PC (polycarbonate) wire and a preparation method thereof.
In order to solve the problems, the invention provides a post-loaded salt for PC wire phosphating, which comprises the following raw material components in percentage by mass: 10 to 30 percent of sodium stearate, 65 to 85 percent of borax, 1 to 5 percent of sodium tripolyphosphate and 1 to 5 percent of sodium nitrite.
Further, the salt loading after the phosphating of the PC wire comprises the following preparation steps: sodium stearate, borax, sodium tripolyphosphate and sodium nitrite are weighed according to the quantity and added into a stirring kettle, and the mixture, namely the salt is obtained after full stirring.
Further, the stirring time is 20-40 minutes.
Further, pouring a certain amount of water into a working tank, heating to a certain temperature, adding 3% -10% of salt, fully stirring and reacting for a period of time, and then soaking the PC wire.
Further, the heating temperature is 70-85 ℃.
Further, the stirring time is 0.5 to 1.5 hours.
Further, the soaking time is 3-10 minutes.
Compared with the prior art, the invention has the following advantages:
1. the concentration range of the carried salt after the phosphorization of the PC line is wide, the process is easy to control, and the phenomena of yellowing and the like are not easy to occur.
2. The quality of the surface of the wire rod after the salt loading treatment is greatly improved, and the wire rod does not rust after being placed for one month at normal temperature.
3. The surface roughness of the dish elements after salt loading treatment is higher than that of the dish elements after saponification, and the phenomenon of loose rolling and slipping of the dish elements in the transportation and stacking process can be avoided.
