Silicone ProductsIs it true that there is peculiar smell?_Why does silicone products smell?_Does silicone products taste normal?
 
Is it true that the silicone product has peculiar smell? Why does your mobile phone case smell? Will it cause cancer if you use it directly? You smell the smell of the silicone plate, is it fake?
 
When Xiao Bian went shopping and shopping yesterday, he went to the daily necessities area and saw silicone daily necessities. He also heard the above doubts. Xiao Bian wants to say that in addition to those black-hearted manufacturers who use recycled materials and waste materials, the raw materials of regular silicone products factories are all made of environmentally friendly raw materials to make protective covers and silicone dinner plates.
 
For example, the silicone raw materials used to make our products are all pure natural and environmentally friendly food contact grade silicone raw materials to produce different silicone products, such as silicone keys, mobile phone silicone sleeves, silicone dinner plates, adult products and other silicone products. Silicone products, smell, it is inevitable.
 
However, the smell of silicone products is weaker than the smell of plastic. Originated from the silica gel raw materials are non-toxic and tasteless environmental protection products. Can use our daily life detergent cleaning, such as hand sanitizer, washing powder, soap and so on. The use of these cleaning materials to clean the mobile phone case will not make the mobile phone case produce any strange or stench, and the user can be completely assured. Silicone sleeve itself, not only silica gel solid material, but also add color masterbatch and vulcanizing agent. The role of color masterbatch, I believe we should understand.
 
This is to make the silicone phone case, or more precisely, to make the silicone product more flexible, so that it will not be easy to break. Although the silicone solid material of the silicone mobile phone case is tasteless, after all, there will be some odors in the color masterbatch and vulcanizing agent, so the silicone mobile phone case will inevitably produce odor. The smell of silicone is not bad.
 
Why is there a smell? The reason is through the machine hot press molding! Many raw materials will smell after high temperature, and silica gel is no exception. In fact, the majority of customers do not have to worry, once the cooling after three days, the smell will slowly dissipate.
 
Why silicone products will smell it: With the continuous improvement of silicone products technology, making the application of silicone products in life more and more widely, but some businesses in the procurement of silicone products found that some silicone products will issue a very pungent smell, then will produce this smell is what question?
 
These problems are mainly some silicone manufacturers in order to save costs, the use of non-environmentally friendly, low-cost ordinary vulcanizing agent, rather than completely through the ROHS detection of environmentally friendly odorless vulcanizing agent, vulcanizing agent is a kind of promotion of silicone raw material vulcanization molding of a catalyst, in the silicone products after molding will volatilize, only a small part of the residue, 48 hours will be volatilized.
 
Vulcanizing agent will not harm human products, but the low-cost vulcanizing machine will produce a burning pungent taste, volatilization time in a month or so, so in the choice of silicone gifts, products as far as possible to choose better performance odorless silicone products. Especially silicone kitchenware, more stringent requirements.
 
There is basically no great taste in the rubber material. The taste problem is mainly the vulcanizing agent mentioned above and the vulcanizing machine. ps: odorless vulcanizing agent should be selected for the selection of vulcanizing agent, and there is basically no smell after the second stage. Note that the two vulcanization time do not choose 200 degrees. 155 degrees or 150 degrees. Baking for 12 hours. If the temperature is high. The product is easily aged. Quality cannot be guaranteed.
 
Therefore, when purchasing silicone products, we must first look at the abrasion resistance, elasticity, tear strength and odor of silicone products. If these conditions are met, it means that the silicone products are of good quality. If they are not satisfied, they will give up so as not to cause financial losses.
Silicone products have a normal taste? It is normal for silica gel products to have smell, because silica gel products need to harden during production and need some added ingredients, which are equivalent to catalysts in chemical reactions. Most of these substances have smell, and some products are more difficult to disperse when sealed and packaged. In silica gel industry, some products leave the factory with fruit fragrance but actually have fragrance additives, while many fragrance additives cannot pass the FDFA test for export to the United States, can not simply think that the product has a fruit flavor, it must be qualified, in fact, the less ingredients added to the product, the more guaranteed.
 
How to eliminate the smell of pure silica gel raw materials are environmentally friendly, non-toxic and tasteless, but after silk screen printing, spray hand feeling oil, YM process, IMD process, lightning carving, dropping glue, water paste and other processes, these processes are done, different taste may be produced. This is extremely prominent in the performance of silicone products. It can be seen that the production of peculiar smell is most likely to appear in various processes after molding.
 
Usually, the process that leads to the most pungent taste of silicone products and plastic products is: silk screen printing and spray hand feeling oil. Screen printing raw materials may have a pungent taste, screen printing after the completion of the silicone products will appear obvious taste. These are also normal phenomena, in the natural ventilation conditions of two or three days, the smell of natural elimination.
 
Although silicone products are non-toxic, but there are many manufacturers in the production of opportunistic, or the process is not perfect, so some products still do not meet the standards. Due to the particularity of the safety requirements of silicone tableware, food silicone products have very strict requirements on the production process, and it takes enough time to remove volatile substances after the product is formed. In order to pursue efficiency, some factories do not have enough processing time, or use unqualified colorants and additives for coloring in the production process, resulting in unqualified product hygiene.
 
Then we should be careful when buying silicone products. If there is a serious smell, we should be careful. Secondly, we should look at the quality of the products. The products with good quality are soft and comfortable. After thousands of folding and pulling, they will not be deformed or damaged.
 
The engineer said: silicone is a natural green environmental protection material, different uses of silicone raw materials are not the same, such as kitchen silicone products, this will use food grade silicone material; medical equipment, medical cosmetic products, to use the relevant medical grade material, through the relevant testing and so on.
 
Silica gel itself is not toxic, but it is indispensable to have a related auxiliary material for the molding of silica gel products-vulcanizing agent, which is a catalyst to promote the vulcanization of silica gel raw materials. After the molding of silica gel products, it will volatilize, only a small part of the residue will be volatilized in 72 hours. The vulcanizing agent does not harm human products, and the rubber material basically does not have a great taste.
 
But most of the products will have good times, so the vulcanizing agent is the same. In order to save some costs, the vulcanizing agent commonly used in silicone products factory may be sub-some, will produce a burning pungent smell, volatile time in about a month, so in the choice of silicone gifts, products as far as possible to choose better performance of odorless silicone products.
 
Especially silicone kitchenware, medical silicone products more stringent requirements. To sum up, it can be seen that silicone products have peculiar smell, and basically will not cause any harm to the human body, but in order to be able to use it, it is purely environmentally friendly products, please buy regular green and environmentally friendly silicone products.Dongguan Mingzhen Silicone Products Co., Ltd.Years of professional silicone production experience, welcome to sample to map customized various types of silicone products.

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
