How to prevent stainless steel screws from rusting

 Analysis of the causes of rusty hardware screws:
1. When the electroplating factory is electroplating hardware screws, the drying is not done, resulting in residual water vapor. Or, after drying, condensate is formed during packaging. Dongguan Electronic Screw Factory introduces to you, it causes chemical reaction, produces bad occurrence, and causes hardware screw to rust.
2. Stored in a humid place for a long time. Over time, the hardware screws will slowly be corroded and oxidized, causing serious rust.
3. When electroplating hardware screws, the electroplating is poor, and the electroplating layer is too thin. Cause rust. All in all, analyze the reasons from four aspects.
 

The four directions are:
1. Storage environment
2. Types of electroplating
3. How to save
4. Use environment.


Therefore, we must pay attention to the key points in the use of stainless steel screws:
1. The surface of the stainless steel screw adheres to the organic juice (such as melon, vegetable, noodle soup, sputum, etc.), which forms organic acid in the presence of water and oxygen, and the organic acid will corrode the metal surface for a long time.
2. The attachment of dust or foreign metal particles, in the humid air, the attachment and the condensed water of the stainless steel screw, connect the two to form a micro battery, triggering an electrochemical reaction and destroying the protective film, which is called electricity Chemical corrosion.
3. In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, and nitrogen oxide), it will form sulfuric acid, nitric acid, and acetic acid liquid spots in contact with condensed water, causing chemical corrosion.
4. The surface of stainless steel adheres to containing acid, alkali, and salt substances (such as alkaline water and lime water splashing on the decoration wall), causing local corrosion. 

Improve strategy:
Storage environment:
The hardware screws must be placed in a suitable environment, should not be too humid, should be ventilated and ventilated, and should not have too much moisture. There should be a bracket to put the hardware screws up and not touch the ground. In terms of electroplating type: the electroplating color with a longer salt spray test time should be selected. Electroplating should be done well, and the electroplating layer should not be too thin. The storage method is similar to the storage environment, and they cannot be placed in a damp place. The use environment is similar. It cannot be placed in an environment with salinity, acidity, high saltiness, high corrosion, high temperature, and high humidity.

Security Screws: Safety Is At Risk Even In Small Stuff

In a world where trust is slowly diminishing, we have become frenetic in handling and keeping things that are significant. But Mother Theresa once said, "Be faithful in small things because it is in them that your strength lies." There's passage reminding us that folks who can't be trusted with small things are people who can't be trusted with big things. Perhaps it can also be said that if we can't trust some literally small things, we can be broken big time. Don't discount the small things for it might be the cause for your serious problem. This also applies with household equipment such as cheap stainless steel security screws. Never dare to belittle the function of small tools chiefly if they have great specifications. Thanks to the genius minds behind screws that are designed to hand a superior level of safekeeping than your standard screws or fasteners. Technically, this innovation was created to avoid crimes like theft and robbery. These gears guara...

How to distinguish between high-strength nuts and ordinary nuts?

What is the difference between high-strength nuts and general nuts, in fact, you only need to understand their standards and other characteristics to easily distinguish them. The so-called high-strength nut is a special bolt with high strength and high fatigue resistance used in special equipment or engineering. Of course, generally high-strength nuts are used with high-strength bolts to achieve better application. We generally see that many bolts with M heads in the market are ordinary nuts, not high-strength nuts. The calibration side of the general hexagonal head nut is the following pattern M30, and M30 indicates the thread standard, that is, the inner diameter of the thread is 30mm. Grade 10 indicates the functional grade of the bolt, and tZn is the surface treatment method. Other types of bolts also have their own expressions, but generally threaded bolts have to use the original functional grade of "M": The functional level of the nut is divided into 3, 4, 4, 5, 5.8, 6...

What are the main types of self-tapping screws?

Many times, the type of screw you decide to use will depend on the material of the screw. Below are a few different types of these specific fasteners and fixtures, and the materials they are most suitable for. Round head screws-Although self-tapping screws are usually used for hard materials, if you need to use thinner materials, round head screws may be the best choice. These are the most common screw types. Many times, this kind of screw is used in combination with a washer. Pan head-If you are using heavy materials, you should consider using a pan head. They are oval in shape with a tapered base, suitable for hard materials. Flat head-For those "home assembly" type furniture, you may want to consider using flat head tapping screws. Generally, they last longer than the nails and bolts given to you in the home assembly package. Phillips Heads-Are you working on plasterboard or timber projects? The crosshead may be your best choice. This type of head provides more control and...
