How transparent effect silicone keys are produced

How transparent effect silicone keys are produced

2021-07-20 10:00:10

Silicone keys can be seen everywhere in everyone's life now. The TV remote controller uses silicone keys, the intelligent electronic lock uses silicone keys, and the POS machine that swipes the bank card uses silicone keys. Even the cars we drive every day use silicone keys. In the heavy machinery industry, silicone keys stand out, how can the silicone panel keys on the heavy crane not only transmit light but also feel good. When molding, transparent color silica gel raw materials are selected, but the silica gel panel keys are generally made thicker, and the light transmission effect is not very good. At this time, light guide column and silica gel keys will be added. If you want the character pattern to be transparent, you need to spray black and white oil. The first layer is sprayed with white oil as the base, and the second layer is sprayed with black oil. After spraying the two layers of color oil, you will enter the next process-laser carving. Import the drawing file of the character pattern into the laser carving machine for debugging. After confirming the position, you can batch laser carving. Like this crane silicone panel key, there are many patterns. It takes about 2 minutes to laser carving 24 buildings, after the laser carving has the effect of light transmission. Transparent silicone keys, as their name implies, are silicone keys with transparent effect. They are made of transparent silicone raw materials. They are generally used in digital products and are used less in other industrial equipment and instruments. The reason is that transparent silicone keys have always been very clean. Some transparent keys with better effect are not exaggerated to describe them as crystal clear, so they are more suitable for high-tech electronic products. Silicone keys use the advantages of transparent silicone keys: they have transparent effect and can be used for keys that need light transmission. The second transparent silicone key does not need to add any pigment, which can reduce the manual color matching process, which can greatly reduce the production time. Due to the light transmission of transparent silicone keys, if customers want to do laser carving process on the keys, they can easily meet.

Silicone sealing ring for the environment adaptability is very strong, it is placed in the strong temperature heating, can be very good to maintain its original shape and state, do not completely deformation, in the high temperature environment will not produce any harmful material composition. Silicone rubber has a wide range of applications, and can make many model products and industrial supporting products, such as various medical grade silicone tubes, bottle straws, silicone strips, pacifiers, silicone tableware, O-rings, gaskets, cups, oil seals, valves, shock absorbers and diaphragms, medicine bottles, silicone sealing rings, etc. Nitrile sealing ring rubber has very good oil resistance. Its oil resistance is second only to polysulfide rubber and fluorine rubber, and has very good wear resistance and air tightness. However, nitrile rubber also has its limitations. Its disadvantages are that it is not resistant to ozone and aromatic, halogenated hydrocarbons, ketones and ester solvents, and is not suitable for insulating materials. Nitrile rubber has better heat resistance than styrene butadiene rubber and chloroprene rubber, and can work for a long time at 120 ℃. Its air tightness is second only second only butyl rubber, the performance of nitrile rubber will be affected by the content of acrylonitrile, with the increase of acrylonitrile content, nitrile rubber tensile strength, heat resistance, oil resistance, air tightness, hardness increased, but elasticity, cold resistance decreased. Silicone sealing ring is not resistant to oil and is not suitable for most thick-shrunk solvents, oils, thick-shrunk acids and diluted sodium hydroxide. Silicone sealing ring has good cold resistance, ordinary rubber is generally -20 ℃-30 ℃, while silicone sealing ring still has good elasticity at -50 ℃-60 ℃, and some special low-temperature resistant silicone can also withstand low temperature. It has high wear resistance, and has the function of automatic elastic compensation on the worn part of the working sealing ring surface, thereby increasing the service life of the sealing member. It has good self-lubricating performance, so it can be safely used in some seals that cannot be lubricated. The silicone key has the characteristics of simple and convenient installation, because its structure is relatively simple compared to other types of seals.

Now there are many kinds of sealing rings, there are all kinds of sealing rings in the market, large and small, thousands of kinds, always make people feel dazzling, but the sealing ring material is now made of silicone products and rubber products, and there are many kinds of sealing rings. The shrinkage of silicone key silicone sealing ring changes with the increase of the density of the rubber content of the vulcanized silicone material, and the shrinkage of the silicone rubber sealing ring also changes with the increase of the hardness of the silicone raw material. Usually, the silicone sealing ring of the heat preservation box that everyone sees is placed in the groove of the small box in the heat preservation box to achieve sealing and heat preservation effect. Few of them are placed outside the small box. My silicone sealing ring of the heat preservation box happens to be placed outside the small box and is in contact with the whole heat preservation box. Can such placement achieve the sealing effect of the sealing ring. In fact, the placement of the silicone sealing ring of this heat preservation box is the same principle as that of other lunch boxes and water cup sealing rings, which achieves the effect of sealing and heat preservation. The placement of the silicone sealing ring outside the small box in contact with the whole heat preservation box essentially seals the whole heat preservation box instead of a single small box. Such placement can make the whole heat preservation box achieve better heat preservation effect. Another advantage of this insulation box silicone sealing ring is that it makes the inside of the insulation box cleaner and has a long service life, because the silicone sealing ring seals the whole insulation box, which is equivalent to blocking the external fine dust from the outside of the insulation box, while the silicone sealing ring is only placed in a small box, and the inside of the whole insulation box is not protected, which is easy to allow dust to enter, thus requiring frequent cleaning. The insulation box is often cleaned with water, thus losing the initial insulation effect, over time, it needs to be replaced with a new heat preservation box. Silicone ring is a kind of sealing ring. Silicone is a kind of rubber material. Because of its special performance, wide temperature range and excellent chemical properties, it is a special rubber together with fluorine rubber. Silicone is widely used in the production of various seals. Silicone waterproof ring is also commonly known as silicone O-ring, which belongs to a product classification of silicone products. Silicone is a ring product made of silicone. Silicone waterproof ring is mainly used for occasions requiring waterproof and sealing.

The main performance characteristics of silicone sealing ring:. 1, good heat resistance and cold resistance, can be used for a long time at -60~250 ℃ 2, ozone resistance, good weather resistance 3, good electrical function silica gel is a colloidal substance with solid characteristics, its basic component is silicon dioxide (SiO2), the physical structure of silica gel is rich micropores and high specific surface area, its appearance is silicon hydroxyl structure, therefore, it has a strong adsorption effect on water vapor or other substances and a selective adsorption separation ability. It is widely used in the fields of adsorption, drying, material separation, purification, high purity preparation, etc. In the field of chemical engineering, silica gel can be used as catalyst or catalyst carrier. Silicone because of its chemical composition and physical structure of the silicone key characteristics, in use has the following advantages:. 1, chemical stability, in addition to hydrofluoric acid (HF) and alkali, insoluble in any other solvents and solutions. 2. Good thermal stability. Type A fine porous silica gel can be used at temperatures within 300°C, while other types of silica gel can be used for a long time at high temperatures of 500-600°C. 3, silica gel has a rigid skeleton structure, with outstanding wear resistance and compressive strength. Silicone sealing rings are common products in life. Although they are small, they play a very important role. They play an important role in the sealing and preservation of certain products. How does the sealing ring turn collagen into a silicone seal. 1. Compression molding: Silicone rubber sealing ring has complex shapes, such as leather cups, sealing rings, etc., which are made by common molding methods. With the help of the mold, the silicone is put into the mold for heating, and then cooled and molded. 2. Injection molding: For more complex silicone rubber seals, such as tire treads, silicone hoses and steel wire surface coatings, injection molding is required. This is a continuous molding method, through various holes (also called templates) The silicone mixture is molded into the extruder funnel under internal thread extrusion. Before extrusion, the silicone must be preheated to make it soft and easy to extrude, to obtain a smooth surface and precise dimensions of the silicone seal ring.

Silicone rubber is physiologically inert, which means that it maintains its shape and size, and this specific ability of silicone keys can be marked by the material properties of silicone rubber, which are less than ideal in terms of mechanical properties, thus explaining why silicone rubber is mainly used in static sealing solutions. Corona-resistant sealing, silicone rubber sealing ring sealing performance how arc resistance, high and low temperature resistance, good aging resistance, high temperature resistance. Lunch box silicone sealing ring, cup silicone sealing ring and so on are facing such problems, so how to clean it. The way to clean these silicone sealing rings is to remove them and clean them with detergent. However, if the bonding port is not firm, it will be easy to pick off or the silicone sealing ring will be deformed and difficult to completely put back into the groove. From this point of view, it is very important to choose silicone sealing rings for daily necessities such as fresh-keeping boxes, lunch boxes, water cups, etc. with firm and tear resistance. Finally, silicone sealing rings with high tear resistance and tensile resistance have been developed, after testing, it can withstand a pulling force of 20KG, so there is no need to worry about picking it off when it is taken off. At the same time, the silicone ring products such as fresh-keeping box sealing ring, lunch box sealing ring, water cup sealing ring and the like produced by our company are all made of imported silicone as raw materials. The main features are high environmental protection, non-toxic and tasteless, good sealing performance, super soft and good resilience, and will return to their original state in time after strong pulling force, so you don't have to worry about the sealing ring will become larger and lead to the result of poor sealing and waterproof performance. Silicone sealing ring has good cold resistance, ordinary rubber is generally -20 ℃-30 ℃, while silicone sealing ring still has good elasticity at -50 ℃-60 ℃, and some special low-temperature resistant silicone can also withstand low temperature. According to the physical properties of collagen materials can be divided into solid silica gel and liquid silica gel. Solid silicone is mainly used for molding products, such as: silicone sleeve, silicone tableware, silicone keys, etc., liquid silicone is mainly used for extrusion molding products, such as silicone nipple, silicone tube, etc.
