China Lotion Pump Exporter Introduces Three factors that affect the accuracy of Plastic Balls :
Plastic Balls have the characteristics of high-temperature resistance, oil resistance, good toughness, and high strength. However, the processing accuracy of plastic balls is not as high as that of other materials. The factors that affect the accuracy of plastic balls are as follows.
Plastic Balls have good toughness and high elasticity. During the grinding process, the pressure of the plastic ball mill is not well controlled, which causes the plastic balls to deform under the pressure, which affects the accuracy of the plastic balls.
Plastic Balls absorb water due to the change inaccuracy. Plastic Balls material has water absorption characteristics. After PA plastic absorbs water, the volume will become larger, and the volume change will also affect the accuracy of PA plastic balls.
Through the above introduction,Mist Pump Suppliers hopes that you can simply refer to the content of this article in future use.

PP Plastic Balls Manufacturers Introduces a Mist Pump is a plastic bottle that can artificially create mist. To put it simply, the high-pressure system sprays the liquid with very fine water particles. These tiny artificial mist particles can drift for a long time and are suspended in the air to form a white misty spectacle, much like the effect of natural mist, called spray. A spray is a mixture of tiny particles suspended in a gas (such as air). These particles may be very small drops of water or paint.
In the Mist Pump, liquid and gas can be ejected as tiny particles are stored under pressure. In the past, people put a gas called chlorofluorocarbons in aerosol cans, but we now know that this gas is harmful to the environment. Now the spray bottle has begun to use other kinds of gas. However, the manual spray bottle is still the best, because it not only has the function of spraying but also uses the principle of air to spray liquid, which will not cause harm to the environment.

The so-called rubber seals refer to products made by processing the rubber collected from the natural rubber tree. Its own characteristics are very obvious, so it is currently used more, but there are many friends who use rubber seals. I don’t know its specific performance, so the following China Rubber Rings Manufacturer will understand the performance of rubber seals.
In terms of physical characteristics, rubber seals are products with high elasticity and plasticity. Moreover, their own mechanical strength is relatively good, hysteresis loss is relatively small, and heat generation is relatively low after multiple deformations. With this feature, its flex resistance is also relatively good. Many users found that the insulation performance of the rubber seal is also good during the test.
The characteristics of rubber seals lie in three aspects: first, it has a relatively small elastic modulus and a relatively high elongation; second, it has relatively good air permeability and can also be used in various chemical media transportation, so Naturally, the scope of application is particularly wide; finally, it can adapt to a variety of different temperatures, whether it is high temperature or low temperature, you can choose it, but you should pay special attention when choosing rubber seals, because different seals There is a certain difference in the effect of high temperature resistance or low temperature resistance. You must first figure out whether the seal you choose can withstand the relevant high temperature or low temperature.

China Rubber Rings Factory Introduces Pe Tubes has a wide range of applications in our lives. As a product with significant advantages, we need to know how to choose a satisfactory product. Let’s take a look at it together:
1. Safety and reliability
This is an important principle in the construction of PE water pipes because the construction of PE water pipes are pressure pipes, and once the water leaks and bursts, it will cause losses to the building and people’s property. The pipe should be able to withstand vibration and shock, water hammer, thermal expansion, and contraction, etc., and withstand the test of time without leaking or bursting.
2. Hygiene
Obviously, the pipes currently on the market must meet the standards, and they can only be put on the market after being tested by a nationally recognized testing department. As far as our current hygiene standards are concerned, the PE water pipes in buildings are all within the scope of hygiene permits.
3. Energy saving
Not only PE pipes but also any pipes from raw material extraction and synthesis, cadmium melting, mill rolling, injection extrusion, all consume energy. From a macro perspective, metal pipes consume more energy than plastic pipes. In the composite process, the steel-plastic composite pipe using the thermal expansion and spraying composite process consumes more energy than metal pipes, and thick-walled pipes consume more energy than thin-walled pipes.
4. Economy
Under the premise of satisfying the use of safe water supply, use the pipe with the least amount of money. While comparing the prices of pipes, it is also necessary to compare the prices of pipe fittings, as well as the construction and installation costs.
5. Sustainable development
Any kind of pipe can be used by people, and one of the important reasons is that it can be recycled and reused and does not produce new pollution.

China Rubber Rings Manufacturer introduces the precautions for buying glass balls:
1. Transparency
For transparency, it is a manufacturer’s process problem. The higher the transparency, the more advanced and advanced the company’s process, that is, the better the quality of its glass beads.
2. Garden rate
There is also the round rate, which is a side description of the manufacturer’s quality standards.
3. Purity and material
Purity and material can also be put together. For glass beads, the main material is glass. The quality of glass greatly affects the quality of glass beads.
Therefore, if the manufacturer uses the glass beads produced by processing some inferior glass, the quality is far inferior to the products produced by crushing toughened glass. In other words, the glass balls made of good glass materials are absolutely crystal clear and can have high reflectivity. Such glass balls are good products.

China Rubber Rings Manufacturer introduces the common classification of rubber seals:
1. Rubber gasket, a sheet-shaped rubber product that acts as a seal between two static surfaces of a metal flange or other connecting parts is collectively called a rubber gasket. It can be made by molding method, or can be punched with vulcanized film. It can be widely used in all kinds of mechanical equipment, playing the role of gasket, sealing, cushioning and so on.
2. V-shaped rubber seal, a kind of rubber seal for reciprocating motion. The cross-section is V-shaped, and it is rarely used alone. It is generally used in combination with a pressure ring with a cloth fabric, a support ring and several V-shaped sealing rings. The number of sealing rings depends on the sealing pressure. The V-shaped sealing ring is molded by rubber cloth or pure rubber. The rubber material is generally NBR. The pressure ring and the support ring are generally pressed by harder rubber cloth. The support ring can also be pressed by hard plastic. V-shaped seal assemblies are mainly used for piston rods and plugs of heavy equipment. This seal assembly can provide good stability and good wear resistance, and can prevent the seal ring from being squeezed into the gap, even under severe conditions, such as axial or radial vibration, sudden pressure, and temperature changes And so on can still provide better sealing effect. It is suitable for hydraulic oil, water, emulsion and other media. The working pressure can reach more than 40 MPa, the surface linear velocity is generally 0.5m?s-1, and the working temperature is -30～120 ℃.
3. Drum rubber seal, a kind of compound reciprocating seal. The section is drum-shaped, also known as piston sealing ring, which is designed for one-way and two-way action pistons. There are different cross-sectional structures according to the requirements of use, but they are all composite elastic sealing rings made by direct molding of NBR and rubber cloth. When using the tape, two plastic retaining rings or L-shaped bushings must be attached. The interference of the sealing lip and the compression of the cross-section make the lip tightly pressed against the sealed surface to ensure the initial sealing. This type of seal is particularly suitable for large hydraulic lifting plugs, stable hydraulic cylinders, etc., and its allowable working pressure is as high as 75MPa, and the linear velocity is 0.5m.

It can be made by molding method, or can be punched with vulcanized film. It can be widely used in all kinds of mechanical equipment, playing the role of gasket, sealing, cushioning and so on.
2. V-shaped rubber seal, a kind of rubber seal for reciprocating motion. The cross-section is V-shaped, and it is rarely used alone. It is generally used in combination with a pressure ring with a cloth fabric, a support ring and several V-shaped sealing rings. The number of sealing rings depends on the sealing pressure. The V-shaped sealing ring is molded by rubber cloth or pure rubber. The rubber material is generally NBR. The pressure ring and the support ring are generally pressed by harder rubber cloth. The support ring can also be pressed by hard plastic. V-shaped seal assemblies are mainly used for piston rods and plugs of heavy equipment. This seal assembly can provide good stability and good wear resistance, and can prevent the seal ring from being squeezed into the gap, even under severe conditions, such as axial or radial vibration, sudden pressure, and temperature changes And so on can still provide better sealing effect. It is suitable for hydraulic oil, water, emulsion and other media. The working pressure can reach more than 40 MPa, the surface linear velocity is generally 0.5m?s-1, and the working temperature is -30～120 ℃.
3. Drum rubber seal, a kind of compound reciprocating seal. The section is drum-shaped, also known as piston sealing ring, which is designed for one-way and two-way action pistons. There are different cross-sectional structures according to the requirements of use, but they are all composite elastic sealing rings made by direct molding of NBR and rubber cloth. When using the tape, two plastic retaining rings or L-shaped bushings must be attached. The interference of the sealing lip and the compression of the cross-section make the lip tightly pressed against the sealed surface to ensure the initial sealing. This type of seal is particularly suitable for large hydraulic lifting plugs, stable hydraulic cylinders, etc., and its allowable working pressure is as high as 75MPa, and the linear velocity is 0.5m.

In real life, we see all kinds of pipe trenches around us sinking after backfilling every day, and it is also a common problem of construction quality. In order to effectively prevent the common problems of falling quality, Rubber Rings Manufacturer introduces the following points that must be strictly implemented :
1. After laying the lower trench, the polyethylene pipe should be covered with fine soil or sand immediately, and the thickness is not less than 30cm to ensure that the polyethylene pipe is not damaged by external forces.
2. For trench backfilling, the bottom of the pipe should be filled first, then both sides of the pipe should be filled, and then backfilled to 0.5m above the pipe. If there is water supply in the ditch, it is necessary to drain it in before backfilling it.
3. The support of the trench should be removed in sequence according to the progress of backfilling under the condition of ensuring the safety of construction. After the vertical piles are removed, the gaps should be filled with sand and soil.
4. The backfill soil on both sides of the pipeline and within 0.5m above the pipe length shall not contain debris, bricks, waste and other debris, and shall not be backfilled with frozen soil.
5. The backfill soil should be layered and compact, each layer should be 20cm, and the pipe should be more than 0.5m, and the machine can be used. The density of each part of the trench should meet the strict requirements.
6. It should be backfilled as soon as possible after the completion of pipeline installation and laying. Because of the large thermal expansion coefficient of PE pipes, it is recommended that the backfill time be selected at a time of the day when the temperature is low.
