The benefits of food grade silicone for baby products mobile phone waterproof artifact:liquid silica gel
 
Food Grade SiliconeThe benefits of being used in baby products are really many baby products [food-grade silicone] as a new material used in nipples, bottles, cups, brushing teeth, even spoons and other products, Dongguan Silicone Products Factory has a wide range of applications and various businesses are keen to flaunt gimmicks. The seemingly unfamiliar name of food-grade silicone has also gradually attracted attention to it with its frequent appearance in mother and infant products.
 
There are too many and too many infant products on the market. When buying, the advertising slogans that attract people's attention are even more hesitant. In fact, no matter what you buy, baby breastfeeding or milk powder, bottles are essential, and the ingredients are the key to whether the product is suitable for children.
 
Careful parents will often disinfect the pacifier, and the easy-to-clean pacifier is undoubtedly the favorite of the mother group. The use of silicone rubber made of baby nipple surface is smooth, easy to clean, can be high temperature disinfection without damage, durable but flexible. It is especially suitable for babies to use after 6 months. At this time, babies will start to have teeth. Because the rubber nipple is too soft, there is no bite taste, and it is easy to bite. If you are not careful, the baby will bite himself.
 
For the health and development of the baby, when the baby is six months old, be sure to use a baby pacifier made of silicone rubber. The nipple is the part that really touches the baby's mouth, so the material requirement is higher than the bottle. The nipple can be made of silicone and rubber. In the selection of materials, in addition to ensuring safety, it is also necessary to better realize the soft characteristics of the nipple. Therefore, most people will choose silicone. Silicone nipple is generally transparent, for food grade materials; and rubber nipple yellow, sulfur content is easy to exceed the standard, the potential "disease from the mouth into the" danger.
 
Silicone has excellent softness, especially liquid silicone, which can be stretched and tearing resistant, and has better shaping effect on products. In addition, the softness of the silicone can be a high imitation of the touch of the mother's nipples, which can soothe the baby's emotions. The rubber will be hard, it is difficult to achieve such an effect. bottle material more, glass bottle has always been the mother of choice. But as the baby grows up, he will like to hold the bottle and eat his own milk. At this time, the heavier glass bottle will give the baby a sense of weight. so, replace the plastic bottle on it?
 
Can be plastic bottles of uneven quality, some plastic bottles are hot water a hot taste, affect the taste. The bottle of silicone rubber products just solves this problem, it not only has all the properties of other materials, but also has excellent special properties. Silicone bottle has good elasticity, the elasticity of silica gel is different from rubber, not the kind of hard elasticity, the elasticity of silica gel is soft and delicate.
 
When the bottle is filled with hot water, it will feel like the skin of the human body. Studies have shown that the touch of the bottle is related to the baby's mood. You know what? A good touch helps your baby to be emotionally stable and more conducive to the development of your baby's emotional intelligence. With the silicone is more and more accepted by people, food grade silicone raw materials to replace regular materials has become a trend in the future development and design of daily necessities, the application field of silicone is also more and more, people's demand for silicone raw materials is also growing, the advantages of silicone gradually being discovered, instead of many other materials in our daily life.
 
The magic of silicone and silicone rubber raw materials is changing our lives. From the product classification, application characteristics and precautions of silicone and silicone rubber raw materials, liquid silicone raw materials, there will be their own differences. The application technology and main application purposes of silicone raw materials and liquid silicone rubber raw materials are well known, and we can find, study and explore more.
Mobile phone waterproof artifact: liquid silicone silicone products are a kind of environmentally friendly, low-carbon and green products processed and molded with silicone as raw materials. The main processing technology is injection molding, extrusion molding, molding. Silicone has other soft rubber class irreplaceable superior performance, such as: good elasticity and waterproof moisture, acid, alkali and other chemical substances erosion, does not contain any harmful substances, at the same time is not easy to deformation; silicone products are often applied to the human body contact with high demand areas, such as baby pacifiers, human organs, medical supplies, etc., the application prospect is very broad.
 
At the same time, silica gel is a non-petroleum product and does not depend on the increasingly scarce petroleum resources. Therefore, it is the general trend that silica gel products become the substitute for similar rubber and plastic products. Among them, injection molding liquid silica gel can produce all high-temperature rubber products. The process is simple, the product accuracy is high, and the output is large. Many advantages will become a new trend of development in the next few years.
 
I. Advantages of liquid silica gel: non-toxic, odorless and tasteless to human body; Good transparency and disinfection; Good touch, elasticity and anti-aging performance; Good high temperature resistance and thermal stability (continuous working temperature up to 180°C); Good low temperature performance (still flexible at -50°C); Excellent electrical insulation, no harmful substances will be produced during combustion
Application range of 2. liquid silica gel
 
3. mobile phone soft rubber sheath contrast-TPU and liquid silicone silicone sheath advantages: non-toxic to the human body, good cushioning performance, high wear resistance, oil resistance, water resistance, good flexibility, comprehensive protection, will not turn yellow. Can be applied to two-color encapsulation mold, can make waterproof sheath.
 
Inadequacies: TPU sheath with slightly poor fit with the fuselage has the advantages of high wear resistance, high strength, outstanding cold resistance, oil resistance, water resistance, mold resistance, good flexibility and insufficient: easy deformation and easy yellowing 4. application case of liquid silicone in mobile phone waterproofing The innovative application of liquid silicone in mobile phone waterproof structural parts solves the problem of mobile phone water ingress, metal silicone, plastic silicone, glass silicone and other secondary molding injection molding methods will become a new trend of mobile phone waterproof. Two-color silicone injection waterproof has the advantages over traditional mobile phone waterproof: due to manual operation in the middle, the assembly accuracy and stability cannot be guaranteed, the disassembly and assembly are easy to damage, and the waterproof effect is poor. The liquid silicone injection waterproof structure is simplified, the overall structure is compact, the assembly accuracy and repetition accuracy are high, the waterproof effect is improved, and the waterproof level is above 5. Liquid silicone injection molding and metal, plastic and other materials secondary molding of high bonding strength, can be repeatedly disassembled, easy to replace and waterproof performance is stable.
 
The injection molding characteristics of 5. liquid silica gel The injection molding characteristics of liquid silica gel are different from those of ordinary injection molding products: liquid silica gel is a thermosetting material; Rheological behavior is as follows: low viscosity, rapid curing, shear thinning and high thermal expansion coefficient; Good fluidity, low requirements for clamping force and injection pressure, but high requirements for glue injection accuracy; Exhaust design is relatively difficult, and some products need to be designed with sealed vacuum structure, the precision of the mold is very high, the barrel and the gating system need to design the cooling structure, and the mold need to design the heating system.
 
6. liquid silicone mold heating design points mold temperature control. Liquid silicone injection mold curing reaction occurs at the mold temperature of 120~150 ℃, mold temperature control is critical: mold surface temperature requirements are stable: the surface temperature is too high, will produce products burnt, parting line cracking, brittle products and other phenomena. If the surface temperature is too low, the curing speed of the rubber material is slow, and quality problems such as product demoulding will occur. The temperature of the mold needs to be heated evenly: uneven heating of the mold and large temperature difference will make the rubber material flow unstable and prone to phenomena such as nebulence and unsatisfactory injection. Location of heater: sufficient distance should be kept between heater and parting line to prevent bending and deformation of the template, resulting in overflow burrs on the finished product; mold temperature control heating mode comparison:

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
