Screw glue, also known as screw fixing agent or anaerobic glue, is mainly used in electrical appliances, electronics, aviation machinery, automobile industry. You'll see it everywhere you have a screw. Generally it is to lock the screw and point it on the mother screw. Let it set slowly. On the one hand, the screws will not fall off in the operation. On the other hand, it has the effect of rust prevention.
If repairs are needed in the future. We just need another 30 percent more power to remove it. Glue can also be applied to the screws. And then you lock it. This will work better. But it's a little more difficult at work. Generally most of the product is done. Finally, glue is fixed to each screw. Let it cure naturally. About 10 minutes after normal dispensing. The surface is not touching. Fully curing about 6-8 hours, under normal conditions, 24 hours fully curing, detachable thread locking glue 4222,4242,4243 and other blue thread anaerobic glue, belonging to low strength, low viscosity screw glue, general disassembly torque is not big, thread permanent locking type anaerobic glue, such as, 4271,4262,4277...... Belonging to the high strength assembly of thread glue, generally need chemical dissolution, heating, or use adhesive to disassemble......
The use of screw glue: no special technology and tools are needed when using, who can simply use; Dispenser can also be used to operate.
How to store the screw glue and how long it can be stored: Keep in a cool place, do not place in a high temperature place, avoid direct sunlight, can be stored for 24-36 months.
After gluing, if it is found wrong, can it be removed? It can be removed by 30% force reversal.
Excuse me, the difference between full and semi-solid screw glue: full fixation is also known as air repellent screw fixing agent, generally used in the screw, after anoxia? Fixed can not be removed, semi-fixed is generally used in the screw lock after the point on the appearance of the screw for fixing, so as to facilitate the removal in the future.
Disassembling method of screw glue Coated with good screw glue products sometimes need to be removed during maintenance, different screw points on different screw glue, its disassembly method is different.
1, small screws (m2-m12) can be used with low strength screw glue products, forcibly removed with alcohol to clean the residual glue, you can apply two times.
2, medium size screw (m12-m20) can be used with medium strength and high strength screw glue, medium strength with torsion damage adhesive layer can be removed. High strength is not very good disassembly, you can use the method of heating to disassemble.
3, 3 large screws (more than M20) are used with high strength screw glue, of course, it is more difficult to disassemble, can be used to heat the screw, heating while twisting, slowly can be opened. Solvents are also used to bubble, but the time is long, and the effect is not obvious.
Now most requirements in line with the European Union, screw glue in line with environmental protection: general regular factory production of screw glue are in line with the ROHS specification.
