　　Huizhou Screw Factory: What are the moisture-proof measures for screws?

Screws are generally called wood screws; they are the kind with sharp front ends and large pitches, which are generally used to fasten wood and plastic parts. The screw is a machine screw with a flat head at the front end. It has a small and uniform pitch and is usually used for fastening metal and machine parts. According to then, Huizhou Screw Factory: What are the moisture-proof measures for screws?

What are the moisture-proof measures of the screw?

1, try to use solvent-free paint.

2. Choose impregnating varnish that does not contain oxidizing components.

3. The curing temperature and curing time should be adjusted. From the perspective of rust prevention, the paint drying (curing) time specified in the paint factory sample is not necessarily sufficient, and the motor has a specific internal shape.

4. Paint that does not contain volatile acids should be used.

5. Choose a coating with good hydrolysis resistance.

What is the anti-corrosion technology of screws?

1. Stainless steel screws are made of metal. There are four main methods to prevent metal corrosion, namely, the nature of the material itself, the environment used, the interface between data and the environment, and the design of improved metal structures.

As long as the surface is protected from corrosion, surface protection is a widely used method.

3. Anti-corrosion treatment on the surface of stainless steel screws refers to applying a maintenance layer on the metal surface through various methods. Its function is to isolate the metal from the corrosive environment, thereby preventing the corrosion process, or reducing the contact between the corrosive medium and the metal surface, thereby avoiding or reducing corrosion.

What are the advantages of screws?

Mechanical advantage: When using, with some electric tools, less power and tool movement is required to relieve pressure.

2, imitation corrosion, rust.

3. There are many kinds of screws.

4. Easy to disassemble.

Huizhou Screw Factory: What are the disadvantages of screws?

1, the initial easy to appear bad phenomenon and reason

(1) Eccentricity: poor installation of the second punch and improper adjustment of the machine.

(2) stubborn head: poor installation of the first punch, improper adjustment of the machine.

(3) burr: one is poor stamping, mainly caused by the gap between the punch and the die hole is too large or the punch is too short.

(4) Mold cracking: The mold is cracked or the R angle of the mold is inappropriate, causing the mold to be scratched by two impacts.

(5) double head: a forming difference.

2. Teeth rolling is prone to adverse phenomena and causes

(1) Machining cracks: tooth plate wear and improper machine adjustment.

(2) Blunt tail: The machine is improperly adjusted and the tooth plate is too old.

(3) Fire: The distance between the two dental plates is too large, or the feeding time is wrong.

(4) Tail tilt: The control screw on the dental plate seat is too tight.

(5) Insufficient tooth mountain: improper adjustment of the machine.

(6) Oblique rod: Improper correction of correction block.

(7) tooth base rough: the pitch is not adjusted.
