silica gel keys appear above several colors silica gel keys quality?
Silicone buttonThere are several colors on the above silicone key quality silicone key as the name implies is a key product made of silicone as raw material, silicone products factory belowName of silica gelTo introduce silica gel buttons above several color analysis of what is silica gel?

1. The mixing of silicone keys is uneven when preparing materials, that is to say, the mixing time is too short after the color masterbatch is added, resulting in the color masterbatch not being completely dispersed evenly, resulting in poor dark marks of silicone products during the molding of silicone keys. This problem can be solved by refining the raw materials.
 
2. If the vulcanization temperature is too high, any kind of silicone color masterbatch has its temperature resistance. When the vulcanization temperature exceeds the upper limit of the color masterbatch, it will cause the color masterbatch to change color at high temperature. If the temperature resistance values of several color masterbatches used in silicone products are different, it may cause the color masterbatch to change color, and the color masterbatch does not change color again. Naturally, the dark marks of silicone keys will appear. It is only necessary to reduce the mold temperature. As for how much to reduce, the answer is to continuously reduce until there is no bad dark mark.

3. When the mold temperature is continuously reduced, the dark mark of the silicone key is solved, but the vulcanization of the silicone product is incomplete (immature). So basically, the temperature resistance of silicone masterbatch itself is too poor, which usually appears on some color masterbatch with bright colors such as red, green and yellow. The temperature resistance of such color masterbatch will be relatively poor. If it is used to mix colors with other color masterbatch, it is easy to cause poor dark marks of silicone products. At this time, it is necessary to consider finding color masterbatch with close colors to re-color to solve such defects.

4. Perhaps such a situation will be encountered in normal production. A certain color paste will not have bad dark marks on silicone keys when it is used before, but it happens to have bad dark marks when it is used in a certain color palette. This is probably because this color cream is not compatible with some color cream, resulting in dark marks after the silicone key is formed. There is no doubt that the general silicone factory often encounters this kind of phenomenon, and the solution is relatively simple. You can replace the color cream. If you know that the compatibility of the color cream is relatively poor, you can directly replace the color cream.

5. The unreasonable placement of rubber material during the molding of silicone keys is the most likely cause of poor dark marks of silicone keys. As the silicone raw material is cut too thick and too narrow, the rubber material gradually flows from the side wall of the key to the key surface when the mold is closed and pressurized, resulting in uneven heating of the rubber material, thus resulting in poor dark marks of silicone keys. On the contrary, the improvement method is to change the cutting specification of the rubber material to thin and wide so that it can completely cover the key type, which can be effectively solved.

6. The silicone key rubber material is stored for too long after it is prepared, resulting in poor fluidity of the rubber material and poor dark marks of the silicone key. In addition, if too much vulcanizing agent is added during material preparation, such defects will also be caused.
The production of silicone keys, the improvement of production power is to make good use of vulcanizing agent, and the most important thing is to improve the vulcanization speed of silicone keys, thus shortening the time required for the molding process of silicone keys. What should be done to shorten the vulcanization time?
BelowName of silica gelThe method of reducing the vulcanization time of silicone keys is introduced.

1. The molding operator accelerates the operation speed and reduces the time outside the mold as much as possible, so as to stabilize the temperature of the silicone key mold and improve the vulcanization speed of the silicone key;
2, the use of vacuum vulcanizing machine production, if there is no vacuum vulcanizing agent, it is best to use steel pipe skid mold in the exhaust, to assist the exhaust;
3, the appropriate increase in silica gel material in the increase of the amount of vulcanizing agent, or the selection of rapid vulcanizing agent, in order to accelerate the vulcanization of finished silicone molding;
4, the structure of the goods and resolution, only silicone keys do not deform and numbness, if it is silicone keys, but also pay attention to whether the load will be high;
5, change the silicone material discharge mode, try to make the mold in the process of pressurization, silicone material can gradually fill all the mold cavity from the side wall of the mold cavity;
6, change the number of exhaust and exhaust stroke, the work experience of the test person request is relatively high, because according to common sense, the greater the exhaust stroke, the more exhaust times, will be more conducive to exhaust.
 
However, this is not the case in practice. The demand is determined according to the structure of the commodity. Some silicone keys with a large exhaust stroke will show poor bubbles, and they will be handled when they are reduced. Summary: With the gradual maturity of the production process of silicone keys and the increasing demand for finished silicone products from all walks of life, the appropriate main factors for improving the vulcanization speed include man-made, vulcanizing agent dosage, commodity structure, discharging mode and exhaust stroke. Only in this way can the enterprise be carried out very well.
Silicone keys are now widely sought after, silicone keys superior performance, coupled with silicone is a non-petroleum products, do not rely on the increasingly scarce oil resources, making silicone keys to become a substitute for similar plastic keys is the trend of the times, silicone keys non-toxic, the application prospect is very broad. Silicone keys are very good, but they are not omnipotent.
 
Let's take a look at the following, what are the reasons for the impact on the quality of silicone keys?
1. the quality of silica gel raw materials will leadSilicone buttonDifficult to dismantle the edge, poor quality of silica gel raw materials, its toughness is insufficient, tear strength is obviously insufficient, in the process of dismantling the edge is certainly very difficult to dismantle the edge.
 
2. the product in the molding process is relatively thick, the burr is actually relatively thick, and the increase in thickness must also lead to the difficulty of edge removal.
 
3. the problems of molding dies, if the self-disassembly design of the dies is unreasonable, the use of the molding dies is too long, the molding dies are seriously worn, the quality of the molding dies is not up to standard, etc., these situations will lead to difficult edge disassembly after production molding.
 
4. vulcanization environmental factors, vulcanization temperature should be appropriate, too high or too low will lead to difficult to dismantle the edge, at the same time, vulcanization time also needs to be well controlled, vulcanization time is too long will lead to brittle products, vulcanization time is too short will lead to vulcanization link no effect, so the vulcanization link must be well controlled.

What is the difference between silicone plug and rubber plug

Silicone plug and rubber plug which one effect is good? Then today we will popularize their difference to where the end point is. First of all, rubber plug products, as a common type of industrial products and accessories, or have strong advantages, such as dust and water resistance, wear resistance, tear resistance, aging resistance, oil seal resistance and ozone radiation resistance, etc., while rubber materials are divided into various types, and the side materials over there can be made of dozens of compound materials, so different attribute functions can be deployed for different needs, as for some industries such as mechanical tight closure, electronic tight closure, vehicle construction and even aerospace and military industry, rubber blocking is the most suitable. Silicone rubber plug and rubber plug have one thing in common. They can be molded in the molding vulcanizer of silicone product manufacturers. The difference is that they are more environmentally friendly, have good high and low temperature resistance, feel better when touching by color hands, and can be in contact with human body skin for a long time. Therefore, silicone plugs for earphones and medical grade silicone plugs are widely used even in food silicone appliances, mainly or because of the material in particular the nature of the achievements of its scope of application. Silicone plug is different. Its material is mainly based on environmental protection advantages, material texture and comfortable application. Therefore, it is used in some electronic products, survival products and small-scale waterproof and dustproof household appliances. Its raw materials are mixed by precipitation method silica gel, high-fine molecular silicone gum and white carbon black. The molecular chain of the product is called heart, soft and comfortable to use! Compared with the materials of silica gel and rubber, they can be compared as follows: new technologies are used in traditional industries. Rubber materials have been heard for a long time in early years, so the comparison of rubber materials accounts for the majority. Up to now, more and more silicone rubber products have been reused because they can replace larger usage compared with rubber, namely environmental protection performance and various technologies, such as shape, pattern and color, etc. www.mingzhen2006.com

What are the fields of application of silicone keys for equipment

Characteristics and uses of silica gel Silicone is a kind of rubber. The vulcanized silicone rubber has heat resistance, cold resistance, ozone resistance, atmospheric aging resistance and good electrical insulation properties. The disadvantage of silicone rubber is that the tensile strength and elongation at break are small, and the compression deformation is large. Suitable for making parts used in high temperature, low temperature, sunlight, atmosphere, ozone environment and electrical insulation parts. Dimensional accuracy and recommend marking tolerance Trajectory material is an elastomer, compared to the plastic material, the direct impact of the shrinkage rate of many and complex factors, precision than plastic parts more difficult to do accurate, in the specific design should be fully considered, there should be no high precision. If the basic size is too large to meet the dimensional accuracy required by the design, it can be solved by the method of deformation of the positioning column with the substrate. Where dimensional accuracy is required, there must be room for convenient mold repair in the design. Etched text and patterns Silicone substrate can be designed out of the trademark pattern and text, in the molding products at the same time molding out. The group and text on the products are convex and concave two types, considering the convenience of mold processing, are generally designed as convex. In order to facilitate the replacement of marks or models, the marked parts can be designed as inserts during mold design. When the product model changes, only the marked parts in the mold cavity can be replaced to meet the needs of mark replacement. As part of this type of article, it should be designed to allow the presence of flash debris at the contour of the insert tile at the marked location. For conductive rubber, the stroke is generally 0.8~1.5mm; the exhaust groove (I. e. gas pit) is designed to prevent adsorption between the PCB and the key action. For tact switches, the stroke depends on the stroke of the switch itself (and the stroke for preventing misoperation), as described later. If the substrate is not bonded to the PCB board, the structural element of the air slot can be omitted. The key design has a hand feeling problem. Different graphs correspond to different hand feelings. According to experience, when (FP-FC)/FP is 40%-60%, the hand feeling is better. Key Typical Structure and Application According to the specific occasions where the keys are used, as well as the specific requirements of the product for the service life, pressing force, and hand feeling of the keys, the structure and application of the keys are shown in the following figure. The life of the silicone key is directly related to the material and the inclined wall structure, and is determined according to the design requirements. Part of the product silicone key life reference: Remote controller: 500000 times; Telephone type: 1 million times; Laptop computers: 4 million to 5 million times; Computer keyboard: 500~10 million; The life of silicone keys for monitoring products is defined as more than 500000 times; The ordinary life of B super silicone keys is defined as more than 1 million times,

The convenience of the use of industrial silicone buttons

In order to solve the above problems and technical defects, after continuous updating and design, a multi-station silicone button trimming machine was invented, and a utility model patent was applied. The utility model relates to a multi-position silicone button trimming machine, which comprises a base, a gantry frame and four cutting cylinders, and the four cutting cylinders are arranged vertically on the top of the gantry frame in a horizontal straight line. The beneficial effect achieved by the utility model is that the structure design is reasonable. By adopting the combination design of four reinforcement tables and four cutting blades on the gantry, the device can simultaneously trim four silicone button products. Thereby greatly improving the efficiency of trimming processing of silicone products. With the continuous expansion of the silicone button market, how to improve the processing efficiency of the silicone button has made producers pay more and more attention. The trimming of the silicone button is an important step in the production process of the silicone button, and the trimming of the traditional silicone button The processing efficiency cannot be improved, which affects the overall production efficiency of the silicone button. Various types of silica gel have different microporous structures due to their different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace other similar materials: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. Silica gel according to its pore size is divided into: macroporous silica gel, coarse pore silica gel, type B silica gel, fine pore silica gel. www.mingzhen2006.com

What are the molding techniques of rubber products?

Calendering: suitable for the manufacture of simple sheet, plate products. It is a method of pressing the mixture into a film through a calender called calendering. Some rubber products (such as tires, tape, hose, etc.) used in textile fiber materials, coated with a thin layer of glue, glue coating process is generally completed on the calender. The fiber material needs to be dried and dipped before calendering. The purpose of drying is to reduce the moisture content of the fiber material (so as to avoid water evaporation and foaming) and increase the temperature of the fiber material to ensure the quality of the calendering process. Dipper is the process before hanging glue, the purpose is to improve the binding performance of fiber materials and glue. Extrusion molding: Used for more complex rubber products, such as tire treads, rubber tubes, and metal wire surface coatings, which need to be manufactured by extrusion molding. The plastic mixture was placed into the hopper of the extruder. Under the extrusion of the screw, a method of continuous molding through a variety of mouth before pressing out, the rubber material is preheated to make the rubber material soft and easy to extrude, so as to obtain rubber products with smooth surface and accurate size. The rubber industry is one of the important basic industries of the national economy. It not only provides people with light industrial rubber products that are indispensable in daily life, but also provides various rubber production equipment or rubber parts for heavy and emerging industries (such as mining, transportation, construction, machinery and electronic products). It can be seen that there are many kinds of products in the rubber industry, and the backward industry is very extensive. Molding molding: can also be used to manufacture some complex shapes (such as cups, seals) of rubber products, with the help of the molding of the female and male molds, the rubber material is placed in the mold and heated. www.mingzhen2006.com
