Test step-salt spray test

One of our quality control introduction-salt spray test as below.

The salt spray test chamber uses salt spray corrosion to detect the corrosion resistance of the tested samples.

The salt spray test is an environmental test that uses artificial simulated salt spray environmental conditions created by salt spray test equipment to evaluate the corrosion resistance of products or metal materials.

The salt spray test standard specifies the salt spray test conditions, such as temperature, humidity, sodium chloride solution concentration and pH value, and also sets technical requirements for the performance of the salt spray test chamber. The methods for determining the salt spray test results include: rating determination method, weighing determination method, corrosion occurrence determination method, and corrosion data statistical analysis method. The products that need to be tested for salt spray are mainly metal products, and the corrosion resistance of the products is examined by inspection.

The history of screw fasteners:

The first person to describe the spiral was the Greek scientist Archimedes (circa 287 BC - 212 BC). The Archimedes spiral is a huge spiral mounted in a wooden cylinder that lifts water from one level to another and irrigates the field. The true inventor may not be Archimedes himself. Maybe he just described something that already exists. It may have been designed by the craftsmen of ancient Egypt to use the irrigation on both sides of the Nile.

In the Middle Ages, carpenters used wooden nails or metal nails to connect furniture to wooden structures. In the 16th century, nailers began to produce nails with spirals that could connect things more securely. That is a small step from this kind of nail to the screw.

Around 1550 AD, the first metal nuts and bolts that appeared as fasteners in Europe were hand-made on a simple wooden lathe.

Screwdrivers (screws) appeared in London around 1780. Carpenters found that screwing a screw with a screwdriver can fix things better than a hammer, especially when it comes to fine-grained screws.

In 1797, Mozley invented the all-metal precision screw lathe in London. The following year, Wilkinson made a nut and bolt making machine in the United States. Both machines produce universal nuts and bolts. Screws are quite popular as fixed parts because an inexpensive production method has been found at that time.

In 1836, Henry M. Philips applied for a patent for the screw of the Phillips head, which marked a significant advancement in the screw base. Unlike conventional slotted head screws, the Phillips head screw has a Phillips head screw head edge. This design makes the screwdriver automatically centered and not easy to slip off, so it is very popular. Universal nuts and bolts connect the metal parts together, so in the 19th century, the wood used to make the machine building was replaced with metal bolts and nuts.
