Do you know what is the silicone key load curve? Silicone button Silicone button is one of the most widely used silicone products, and its main function is to execute operation commands for mechanical equipment. Most of the silicone keys with load requirements are conductive silicone keys. Today, Xiao Bian came to popularize science about what is the load curve of silicone keys. So, what is the silicone key load curve? Silicone button The load curve means that when the silicone key is pressed, the force of the press is reflected in the curve of the synchronous change with the stroke of the key. The stroke of the silicone key is inversely proportional to the performance of the resilience. The larger the stroke, the smaller the resilience. On the contrary, the smaller the stroke, the greater the resilience. The higher the hardness value of the silicone key conductive adhesive, the higher the load value, but the relative service life will be reduced. Silicone button The load curve of the silicone key is actually a feedback form of the silicone key, which can help the technical personnel to study and analyze the performance of the silicone key.

The phenomenon of tensile difference in mold silicone products

The phenomenon of tensile difference in mold silicone products

2021-07-26 15:50:31

How to solve the problems in the use of silicone mold? What is the reason for the difference in tensile force of mold silica gel? Silicone Mold Products Mold silica gel has the characteristics of high temperature resistance, good tensile force, many times of mold turning and high times of repeated use, which is the favorite of silicone products factory. However, some manufacturers in the production of mold silica gel in order to make the silica gel easier to operate, in the silica gel added a large number of silicone oil, we all know that silicone oil can destroy the molecular weight of silica gel, silica gel viscosity decreased, making the silica gel becomes more soft, easier to operate, resulting in silicone mold in the production of tension difference. silica gel thickening solution? Generally speaking, liquid silica gel is good for half a year. If the viscosity of silica gel exceeds one year, it will thicken with the increase of time. The expired liquid silica gel will solidify into a ball with almost no fluidity, which will make us very puzzled. Expired liquid silica gel will have very poor fluidity and almost form a mass, which will cause difficulty in mixing AB glue and non-leveling when pouring glue. If a large amount of silicone oil is added, the tear resistance and toughness performance of silica gel will decrease after curing. Silicone Mold Products How to increase the fluidity of liquid silica gel without affecting the performance of silica gel? There is something called expansion bolt on the market. You can buy a suitable length according to the amount of silica gel. After buying it, break the front opening of the outer jacket of the expansion bolt into a cross shape with pliers, then tighten the nut and tighten it. A simple mixing head is ready. Silicone Mold Products Next, the stirring head was stuck on the electric drill and began to stir frantically. After stirring, the silica gel regained its fluidity again. The newly stirred liquid silica gel is a little hot due to friction and molecular movement, and there are many bubbles. It is unwise to use it immediately at this time. On the one hand, it is easy to bubble; on the other hand, it is easy to bubble because of its own heat, which will speed up the reaction speed; on the other hand, it is easy to bubble. Let it cool for a while and then use it again.

How transparent effect silicone keys are produced

How transparent effect silicone keys are produced

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.

How to produce silicone sealing ring with good cold resistance

How to produce silicone sealing ring with good cold resistance

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.

Influence of hardness and softness of silicone sealing ring: in many cases, the function and structure of the product can be completely changed according to the different softness of silicone products. therefore, the silicone sealing ring will present some problems that cannot be prevented, such as extrusion gap, excessive stress, too high hardness, no rebound of product deformation and other factors, due to the selection of different hardness and softness of silicone sealing ring in the application process. Gap problem of silica gel sealing ring: the gap problem can be divided into several factors. one is the rubber problem of raw materials. many silica gel materials show poor resilience due to formula. the lack of tensile force leads to leakage due to less strength in the application process. the processing problem of silica gel ring manufacturers, such as brittle products, which leads to thinner curling thickness, is easy to present this kind of problem, the soft product leads to the inner bulge of the rubber material, which is not ripe, and the deformation after long-term stretching and compression presents a gap problem. Different sealing methods of silicone sealing ring. Sealing ring 1. Static tight closing: cylindrical static tight closing equipment is the same as reciprocating tight closing equipment, usually W = 10% ~ 15%, and simple surface tight closing equipment W = 15% ~ 30%. 2. As far as dynamic tight closure is concerned, it can be divided into three working conditions:. A. reciprocating motion close tightly usually take W = 10% ~ 15%. B. tight closing of rotary movement must consider the scorched blush effect when selecting the contraction rate. generally speaking, the inner diameter of the o-ring for rotary movement is 3% ~ 5% larger than the shaft diameter, and the contraction rate W = 3% ~ 8% of the outer diameter. C. low friction transport with O-ring, in order to reduce the friction resistance, usually choose a smaller tightening rate, that is, W = 5% ~ 8%. Today's scientific and technological skills, the sealing and protection skills of many products still have certain defects in the actual process, and the selection of silicone (a kind of rubber material) as the raw material of the seal is a common one for us, so silicone sealing ring, as a kind of seal used in many aspects, often presents some unexpected function problems in the normal application process, which cannot reach the actual problems and cannot show the effect of the product. Analysis of the causes of failure in the use of silicone seals.
