How to deal with the waste silicone material_silicone sealing ring aging problem_how to buy a good silicone protective sleeve
 
After years of development, silicone solid-state silicone molding technology in our country has been widely used in many industries, including construction, machinery, electronics, medical and other fields. Among them, silicone products can account for 60%. Due to its wide application and wide range, many suppliers in the world are still in short supply. At the same time, it also has a special market for recycling waste. Silicone waste materials have the utilization value of recycling here.
 
Silicone raw materials are different from rubber, plastic and other materials, and the recycling price is more than ten times that of them, while the price of waste raw materials is also very expensive. As the raw materials have been rising since last year, and silicone waste has also been affected, the maximum price has reached about 11000 yuan/ton, while the average price in some areas this year is about 6000-8000, but it is also very high,
 
Natural expensive natural also has its recycling value. Silica gel waste mainly comes from burrs and waste products after hydraulic molding in the molding and vulcanization process of mixed rubber. It is also essential for silica gel products to have burrs in the molding process. Millions of tons of silica gel waste materials will be treated every year in our country. Therefore, due to the addition of different auxiliary agents to the waste rubber materials, it has outstanding performance in all aspects, aging resistance, weather resistance and other excellent properties,
 
It will not decompose naturally for decades. At first, when the correct treatment method was not found, how to deal with tens of thousands of tons of silicone waste has been crying for the development of silicone products manufacturers. With the current scientific and technological water, silicone waste will be melted and reacted to obtain siloxane ring (DMC) after recycling. At the same time, there are many mixed substances. Technically speaking, siloxane is mixed with sulfonic acid for cracking reaction,
 
The DMC colleague contains a small amount of pigment and sundries, and can extract colorless organic silicon and inorganic silicon after rapid filtration, so there is no problem with the raw materials used for desiccant, silicone oil and silica gel low-end products! And silica gel raw material recovery after the treatment method is basically always. Therefore, the desiccant and discoloration silica gel you currently see may be processed as waste materials!
 
In life, many products have a little problem but it is very headache, such as many sealing products and so on. In many cases, the sealing rings and silicone fittings used in life are aging and failing, and their service life is affected. For common joint seals and pipeline sealing rings and so on, a small sealing fitting is broken but affects the overall use. Therefore, it is more important for silicone sealing rings to purchase, otherwise, it will seriously affect the whole product.
 
Silicone sealing products can be seen everywhere in life, such as water pipes, drinking fountains, switch valves, etc. Therefore, its adhesion and tightness are still very important. When it comes to quality problems, aging and life span mainly affect it seriously. Therefore, in addition to the use of various environments, the standard of material selection is also very important. Of course, it is also important in the production and processing of silicone product manufacturers, A more qualified silicone sealing ring can mainly distinguish its quality problems from the following points!
 
First of all, whether the raw materials are qualified, and secondly, whether the vulcanizing agent added to the rubber mixture raw materials is qualified, and the main reason why the silicone products are affected by aging is caused by the raw materials, such as light, heat, oxygen, liquid and so on. Secondly, the reason for the size deviation of the vulcanization process!
 
If the sealing is not tight enough, you can find the reason from the product size and the tolerance range of the mold size. The pressure bearing degree is too small, and the long-term active movement sealing products can be found from the vulcanization temperature and time, and the hardness and softness effect of the product can only be achieved under the normal time and temperature.
 
After summing up, in addition to the normal use of the product, in addition to the impact of the environment and the quality of the product itself, we can find the problem from different reasons, in which the main reason for aging symptoms is production and processing and excessive fatigue caused by use.
How to buy a good silicone protective sleeve
 
There has always been a saying in life that "no matter how much money you earn, half of it may be owned by someone else, no matter how big you live in, half of it may be free, you drive in a good car, the traffic is the same, you use a good mobile phone, half of the functions are useless" so it is the same if you choose an expensive mobile phone case and are not satisfied! Therefore, the choice of things is still practical, and the purchase of silicone products is the same, just like silicone protective covers, which are not practical, not good-looking and not like, so they will not be bought because they are a brand, will they?
 
Many friends said that they could not find a mobile phone protective cover they liked, and some people said that they could not always buy a satisfactory silicone protective cover, so Mingzhen Silicone Products Xiaobian answered the difficult problem for you! The demand for mobile phone protective covers is widespread in the market today. Many friends will choose a protective cover for their love machines. Therefore, many merchants in the market have increased their purchases. This has also caused the rise of many silicone product manufacturers.
 
In recent years, from the perspective of silicone products industry, many new stars of silicone enterprises have appeared all over the world. The quality of products can be controlled as profits, regardless of the experience of merchants and customers. They use low-grade materials to save costs and do not use various unreasonable production such as oil injection or baking process. Therefore, many friends say on the Internet that "his mobile phone case is yellow and his mobile phone case is sticky again" and so on.
 
So I want to buy a satisfactory protective sleeve and also have some simple understanding of silica gel! Now the mobile phone protective cover is not only a kind of decoration, a kind of jewelry, the following famous silicone products manufacturers to explain how to buy high-quality protective cover, the first choice from the appearance above, bright color without dark lines, feel comfortable, flat surface.
 
In terms of toughness, the toughness of general silicone products is very strong, so you can pull the rope to about 50% to try whether the resilience is qualified. If white mist appears on the surface after rebound, the quality is low.
 
In terms of smell, the product usually has a little smell when it comes out of the oven, but the manufacturer will eliminate the smell after baking. If you buy enough products for long-term use and disperse them, then there is a problem. The product feels a little greasy or sticky. There are more silicone oil in the raw materials of the product, and it will be sticky after long-term use. Pay attention to purchasing white or transparent products and ask the merchant whether platinum vulcanizing agent is used, if not, the product will turn yellow for a period of time!

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! YAG laser marking machine, the general laser marking machine can not do through the key! Light transmission keys, also called light transmission buttons, are widely used in electronic products. In dark environments, they can accurately and accurately find each button. The light transmission keys include a light transmission key body, an electronic switch located below the key body, and a luminous body. The luminous body is arranged on the lower side of the key body. A light guide body is arranged below the key body, and the light guide body has a body, the upper side of the body extends an extension to the position where the electronic switch is located, the outer surface of the extension is a first reflective slope, the lower surface of the body is a second reflective slope and doubles as a light touch surface that can be contacted with the electronic switch, and a light input part connected with the extension part and arranged corresponding to the light emitting body, the light emitting body emits light, the light is emitted to the first reflective slope through the introduction portion, and is reflected by the first reflective slope into the body, and the light entering the body is reflected by the second reflective slope out of the key body. The structure makes the light emitted from the light emitting surface of the key body more uniform, the key is more beautiful, and the user can accurately find the corresponding function key. The pattern and text on the keys are processed by laser typing! In our life, there are many keys and buttons that use laser typing and can transmit light, such as mobile phone keys, car audio keys, computer keys, and various electronic and electrical keys! www.mingzhen2006.com
