How to choose a wave spring manufacturer?

A wave spring is a thin ring-shaped elastic metal element composed of a plurality of wave peaks and valleys, which is simply referred to as a wave spring. A single-layer wave spring is an elastic element with a number of wave crests and valleys on a metal ring, while a multi-layer wave spring is composed of many single-layer wave springs.

Wave springs have the ability to save space and are elastic elements with several peaks and valleys on a thin metal ring. The ratio of wave spring load to deformation is called spring stiffness. The greater the stiffness, the harder the spring.
Its main functions are:
① Control the movement of machinery, such as valve springs in internal combustion engines and control springs in clutches.
② Absorb vibration and shock energy, such as buffer springs under cars and train cars, and vibration-absorbing springs in couplings.
③ Store and output energy as power, such as clock springs.
④ Used as a force measuring element, such as a spring in a force gauge, spring scale, etc.

Wave springs are widely used in motor, textile machinery, machinery manufacturing, petrochemical, hydraulic equipment, automotive and other industries. The wave spring is mainly installed in a bearing room or a hole suitable for the specification. The installation space is small, and it has the special function of reducing noise and vibration.

Compared with ordinary coil compression springs, wave springs can save at least about half of the space when they bear similar loads, which can reduce the overall size of the equipment and save costs. Wave springs are used in places where the load and deformation are not large, and the spring stiffness is small, and axial preload is required.

So, what causes the wave spring to fail during use? The following is a brief analysis by Weihui Spring.
The causes of wave spring failure generally include:
First, the material of the spring. Springs made of surface-reinforced materials have a longer service life than untreated materials. Defective materials also affect the service life of springs, which means that springs fail prematurely due to fatigue.

Second, the spring temperature. The wave spring has strong elasticity, electrical conductivity and abrasion resistance at normal temperature, but as its temperature increases, the elasticity of the spring will gradually decrease, and it will gradually become fatigued and cause failure.

When designing a wave spring, manufacturers should choose a reasonable wave height and material thickness according to the load and displacement, effectively control the wave spring stress, and use the adjustable wave number to more effectively control the fatigue failure of the wave spring.

Genuine leather handbags get dirty after a long time,don't throw them away!

Bags have been used for a long time. In addition to wear and tear, stains will always fall on the bags, which is very difficult to clean, or even not clean at all, and can only be lost, but it is really a waste!

White bag is yellow, don't know how to clean it?
You can use face creams and hand creams to remove yellow hand creams and face creams at home. Do not discard them. Cleaning leather products often has unexpected results. Be sure to wipe it a few times to see the effect. If you have milk and petroleum jelly in your home, you can coat the freshly treated yellow part as a daily maintenance method to prevent the appearance of yellow.

There are oil stains on the bag. It is always inevitable that the leather bag is stained with oil stains. You can directly use detergent, but you must brush it gently to avoid damage to the leather. If it is a white leather bag, you can mix 1:10 with bleach and water and then wash it.

If there are traces of strokes on the bag, you can squeeze a little shower milk in warm water, and then wet the cloth to wipe the traces of the strokes on the bag, and then wipe the water off the bag with a dry paper towel. If you get it with a ballpoint pen, use some toothpaste and a small amount of soap to gently rub, then wipe with alcohol.

There is also a very common problem, that is, the bottom of the handbag is prone to wear scars. If it is not handled in time, it will wear out and become worse, and even the most expensive bags will not look textured. In fact, as long as you apply the adhesive on the edge of the strap evenly, do not apply it too thick, apply a layer first and wait for it to dry, then apply a layer, so apply a total of about five layers, after drying, it will be the same as the new one La.

How to clean up stained stains. Wear light-colored leather bags with jeans and wear them over time. The clean leather bags will be stained with light blue! Dip a cleansing milk on a cotton pad and wipe back and forth a few times to remove the denim stains on the bag. I chose makeup remover because it doesn't have irritating chemicals, so it won't hurt your purse.

So how to maintain the bag?
Before each storage of leather products, they should be dusted and cleaned, and then the leather maintenance oil should be applied. Apply oil to a clean cotton cloth before wiping the surface evenly. Leather bags can be wiped with a high-density nano-sponge. If it is slightly dirty, you can use a white eraser of a normal pencil to quietly remove it. Severe soiling can be wiped with a high-density nano-sponge with a wipe of water. Before cleaning, wipe it on an inconspicuous area to see if it fades, and then use genuine leather handbags care agent to clean and maintain it, which can prolong its life.

How to choose between laminated safety glass and tempered glass

When choosing safety glass, whether it is decorative glass or functional glass, there are usually two choices: tempered glass or laminated glass. Both products are of the "safety glass material" type, which means that they are in compliance with current safety glass regulations, so they can be used indoors, satellites, railings and other places that may be considered dangerous.

Tempered Glass
Tempered glass is made by heating and cooling a standard piece of glass in a tempering furnace. Before placing the glass in the tempering furnace, it must be pre-cut and trimmed, then heated to approximately 1200 ° F, and then quickly cooled. This process is also called quenching. The quenching process hardens the glass, so its strength is about 4 to 5 times before the tempering process, so it is less likely to break. If it breaks, the tempered glass will break into small pieces and will not cause serious trauma.


Laminated Safety Glass
Laminated glass is basically a glass sandwich, made of two or more layers of glass with a vinyl sandwich in between (like the windshield of a car). The glass will tend to stay together, and if one of the glass boxes breaks, it can be used as a safety glass material. Another major advantage is that it can block 99% of UV transmission, has noise reduction properties, can be cut after lamination and can polish the edges. Some thicker multilayer safety glass can even be used as anti-theft and bulletproof glass.

Because laminated glass has better impact resistance than other types of glass, this is the glass used in modern windshields. The interlayer interlayer gives the glass structural integrity and avoids breaking like tempered glass. This is the key to effectively deploying the airbag and keeping the occupants in the car during a collision.

Tempered Glass VS Laminated Glass: how to choose the right one for your job
Therefore, for strength and breakage resistance, tempered glass is usually considered first. Considering flexibility, UV resistance, safety and sound considerations, laminated glass is usually the first choice. Both are considered safety glass materials and can be obtained in various thicknesses, colors or tones. When properly installed, both are easy to clean and maintain.

Generally, the price of laminated glass products is slightly higher than that of tempered glass of the same type and thickness. The optical clarity of laminated glass and tempered glass is excellent, no matter which product can provide you with satisfactory service for many years.

The Geotextile Filter Fabric

When describing the reasons for the benefits of growing plants, it is mainly geotextile made of Geotextile Filter Fabric. This fabric can be used for air pruning, drainage and ventilation of the soil where the plants are located. Geotextiles have been in existence since the early 1950s and have been used for beautification and demolition. Geotextile Filter Fabric is woven in different ways for different applications, and they vary from mesh, warp-knitted and closed fabric or non-woven fabric.

Soil control: Initially, geotextiles were designed to replace granular soil filters, and can also be used to control erosion control of concrete seawalls and other areas that may cause soil erosion. Therefore, people have noticed that both sufficient permeability and soil retention are required, as well as sufficient fabric strength, which sets the tone for the use of Geotextile Filter Fabric.

Civil Engineering: Geotextile Filter Fabrics are still used in civil engineering projects around the world, including dams, retaining structures, airports, reservoirs, roads, canals, railways, and embankments! The permeability of the Geotextile Filter Fabric protects the soil used to create these frequently used areas from heavy rain.

Fossil protection: Letoli, Tanzania has many sets of human fossil footprints, preserved in volcanic ash about 3.7 million years ago. A set of footprints called Laetoli was visited by a team of experts and Geotextile Filter Fabrics were used to preserve these prints, allowing the surface of the fossil to breathe and protect it from the root growth of the surrounding plant life.

Geotextile is a wonderful invention. Yingfan's geotextile filter fabric is durable, washable, and reusable for up to 5 cycles. It is the best choice for growers.
