Silicone ProductsWhat are the characteristics
 
Silicone products is a kind of silicone as raw material of soft products, from a large scope, silicone this raw material is a kind of rubber and plastic. So what are the characteristics of silicone products? The following is the Dongguan silicone products factory name vibration silicone for you to unlock the password. The main features of silicone products are: high temperature resistance, easy to clean, long life, soft and comfortable, diverse colors, environmental protection, non-toxic, electrical insulation performance, low temperature resistance, electrical conductivity, weather resistance, thermal conductivity, radiation resistance, etc., currently According to the limitations of science and technology, these features can be effectively applied.
 
1, temperature resistance, silicone this material is a kind of temperature resistant raw materials, the production of silicone products is naturally very temperature resistant, because in the process of production, the product molding temperature can reach 230 degrees Celsius, the lowest is the critical temperature of 40 degrees. Generally speaking from professional technology, this requires manufacturers to grasp all aspects. Control each process, so that the products produced will not be locally bad or the rubber is not cooked.
 
2, easy to clean, silicone products is a waterproof product, placed in the water is not any change, this is the silicone products are born. Moreover, the silicone kitchenware produced can be boiled and disinfected in high-temperature hot water, and can also be washed in a washing machine or dishwasher without washing the silicone products.
3. Long service life. The space mechanism of silica gel material is also very complicated, but its chemical properties are also very stable. It will not react with general chemical substances. Except for strong acid and strong alkali, the general weak acid and weak alkali will not change. These few yuan give silica gel products good characteristics. The produced silica gel products have long service life and are also very durable. Therefore, the general opinion is silica gel products, in particular, silicone products such as silicone kitchenware, used 3-5 years is no problem, compared to other materials, silicone products are more durable.
 
4. Soft and comfortable. The characteristic of silicone products means that silicone can produce some soft daily necessities, such as silicone baby shampoo. This product is an oval shape with a suction cup behind and some small soft needles on the surface. These small needles have the function of massaging and exfoliating the skin, and colleagues will not hurt the surface layer of the skin, this is why the silicone baby shampoo produced by Dibo silicone manufacturers is very popular. Many trading companies and Taobao sellers have come to place orders. This production line is also very busy. Because this silicone baby shampoo is soft, in addition to washing the baby's hair, colleagues can be used as a young woman to wash her face.
 
5. Various colors. When the color masterbatch and vulcanizing agent are added to the silica gel raw materials, the color changes immediately. In the whole process, the transparent color of the silica gel itself changes to the color ratio added. Therefore, the color of the silica gel products is very beautiful and bright. Whether it is used as silica gel kitchen utensils, silica gel ornaments, silica gel gifts or our commonly used silica gel daily necessities, silica gel products suitable for various places can be produced.
 
6. Environmental protection and non-toxic. In China, many friends do not know materials such as silica gel. They do not know that silica gel is an environmentally friendly and non-toxic material, which leads to many misunderstandings. Some even say that silica gel is a toxic substance. In fact, these are all misunderstandings. In addition to the products I mentioned above, the most common thing to do is silicone nipples, this is a household product that has been used. Silicone nipple is a kind of silicone products produced by silicone, but the production process is different.
7. Silicone products are mixed glue made of silicone raw materials after rubber mixing in an internal mixer. The formula is designed according to the characteristics of the required silicone products during rubber mixing, and the required product hardness is determined. The product is molded by a silicone flat vulcanizer. After the product is formed, the final flash treatment is carried out to make the surface of the product smooth and free of burrs.
 
8. Silicone is a hot-soluble thermosetting elastomer, while plastic is hot-soluble and cold-hardened. Silica gel due to the different types of sulfide, the molding and curing temperature range, there is a considerable gap, and even due to climate change, indoor temperature and humidity. Therefore, the production conditions of silicone products need to be adjusted at any time, if not, the quality of the products may be different.
 
9, silicone products molding, after large pressure pressing, because of the elastomer is available within the force can not be eliminated, in the molding from the mold, often produce very unstable shrinkage (silica gel shrinkage rate, due to different kinds of glue and there are differences), must be after a period of time, in order to slow and stable. Therefore, when a silicone product is designed at the beginning, regardless of the formula or mold, it is necessary to carefully calculate the coordination. If not, it is easy to produce unstable product size and low product quality.

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

How to print the pattern on the transparent key

Some laser marking machines have played opaque keys. While using laser typing to knock out the paint, they will also burn the plastic parts that can transmit light, but cannot transmit light! Changzhou laser marking machine has a special device, which can adjust the machine to the function of laser processing light-transmitting key. The laser can clean the paint sprayed on the surface very clean without burning light-transmitting plastic, thus realizing light-transmitting key laser processing!
