Silicone key manufacturers yellow how to do molding process

Silicone key manufacturers yellow how to do molding process

2020-10-23 10:50:01

Nowadays, silica gel has become an indispensable raw material in our daily life. It is shining in the fields of daily life, medical treatment, mother and child, digital electronics and so on. And we are more common to the silicone products are silicone pot shovel, silicone nipple, silicone gloves, silicone phone shell, silicone fresh-keeping cover, silicone medical accessories, etc., however, some silicone products in our long-term use will appear yellow phenomenon, like silicone nipple from the initial transparent into yellow is particularly obvious, then the cause of silicone products yellowing is the long-term use of the process will inevitably be silicone key manufacturers exposed to the air, transparent silicone products and air physical phenomenon caused by oxidation of silicone products yellow phenomenon, how to solve this problem. 1. It is produced with high-quality silicone raw materials with high transparency. 2. By adding anti-yellowing vulcanizing agent, the oxidation and yellowing of silica gel products can be effectively inhibited. 3. In terms of process, control the production temperature and vulcanization time of the mold of the silicone button manufacturer. Silicone as a common environmentally friendly raw materials, because of its many advantages and loved by consumers, silicone button factory its softness and safety and environmental protection performance is widely used in industrial sealing and medical equipment, which is the most important of its working temperature in -40~240 degrees Celsius is plastic products can not be compared. Extrusion molding process is just like our toothpaste extrusion. The head of the silicone extrusion equipment is also the cross-sectional shape of the product. It has a certain length. Under the action of force and temperature, the product coming out of the machine has been vulcanized and molded. The products processed and molded by this process are generally strip-shaped products with various cross-sections, rectangular strips, annular silicone tubes, etc. Silicone key manufacturers can also use the process of dripping liquid silica gel, but this process requires liquid silica gel. The liquid silica gel is installed in the syringe, and the raw materials are dripped on the mold by pneumatic and manual operation, and heated and vulcanized. This process is a manual process, which requires more labor and low production capacity, but it has a more important feature, that is, the products made by this process can drop out many colors according to the requirements. The silicone key manufacturers are also very delicate and concave and convex. What they do more are silicone bracelets of various colors, silicone mobile phone shells with various color patterns, various exquisite cartoon silicone key chains and other small pendants.

Where is the difference between silicone products and latex

Where is the difference between silicone products and latex

2020-10-10 11:50:13

Silicone and latex itself is difficult to distinguish, so many times want to distinguish a product is a silicone key manufacturers or latex products will be very troublesome 1. Look, the surface of natural latex will have crust, which looks like milk skin. Pressing will produce natural folds. When synthetic latex is distilled at high temperature, the added powder will turn black. Therefore, a large amount of fluorescent agent and whitening agent will be added to cover up this phenomenon, so the synthetic latex will look very white and the surface will be oily. 2. Smell, in fact, latex was originally another name for natural rubber juice, so the essence of latex is still rubber juice. Although rubber juice looks like milky white like milk, their essence is different, so there will be no so-called milk fragrance. Pure natural latex products should present a faint rubber smell instead of the so-called milk fragrance. 3. Touch, natural rubber feels soft and moist, a bit like touching clothes that are not dry, a bit moistening hands, and feels very good, like touching baby's skin, and the product can be folded in half and then let go. Natural latex will be more elastic and will bounce away, while silicone key manufacturers do not have this ability. 4, tearing, silicone key factory natural latex is moderately strong, so it cannot be torn hard, hard tearing will tear the natural latex products, synthetic latex because it is added with adhesive, so it is very strong, very resistant to tearing. Silicone key manufacturers have been widely used in various fields since we used them. Maybe you have a silicone accessory beside you now. The price of silicone accessories is also very reasonable in the market. You cannot buy a car or a house. The customized price of silicone key manufacturers is based on the production quantity. The more the production quantity, the simpler the process, the cheaper the price. If the quantity is small, the production process is too long, time is too long, then the price of liquid silicone will be a little higher, so some friends also consider the price of silicone button manufacturers. A lot of silicone jewelry appears in major markets and has been bought by many friends. However, some friends are hesitant and still have the same defensive heart as rubber to silicone key manufacturers. Many friends who do not know about silicone still do not deny the statement that silicone is poisonous. Although they know that silicone jewelry is very popular in the market, the defensive heart is indispensable. This is also the right choice, however, I hope that after reading some silicone safety statements about silicone key manufacturers, I will try to slowly understand the use and advantages of silicone.

How to deal with deformation in silicone key production

How to deal with deformation in silicone key production

2020-10-09 11:30:51

Not to say that the silicone will not be permanently deformed, if the long-term stretch does not rebound when there will be deformation, what factors affect the deformation of the silicone key manufacturers. 1. Long-term immobility causes permanent deformation. Long-term use under high pressure conditions is easy to deform for products with hard materials under high pressure. 2. The influence of stretching rate is determined by the hardness and softness of the product. Generally, the winning rate of silicone rubber can reach 300 to 600 (relatively soft material). However, excessive stretching in the use process of silicone key manufacturers will directly lead to deformation and loss of stretching degree and permanent deformation. Therefore, it should not be excessively elongated in the use process, regardless of industrial products or raw materials. Live supplies or silicone jewelry are the same. 3. Influence of temperature occasions. In a humid place, when silicone liquid silicone is working, it will gradually deform when stretched during use under humid and high temperature conditions. However, with the adaptation and decrease of temperature, it will also lead to slight deformation of silicone key manufacturers. Therefore, whether it is accessories or sealing products used in the industrial application of silicone key manufacturers, in addition to human reasons, try not to let silicone key manufacturers stretch for a long time. The storage of silicone key manufacturers also requires certain skills. 1. The newly vulcanized raw materials are placed in a dry place. Due to the softness of the materials and the heat of mixing, a fan can be used to wake up and dry the raw materials. Generally, the raw materials are placed in high temperature, acid ozone and humid places, which will lead to the aging phenomenon of the rubber and accelerate the performance decline. The dispersion of rubber molecules in liquid silica gel leads to uneven molding color and dark stripes. Long-term storage leads to toughness and decreased expansion and elasticity. 2. The method of storing finished products can be to seal the packaging and sealed bags to prevent dust from entering, and to keep ventilated in a dry place to prevent the product from deteriorating due to oxidation resistance and deterioration. Do not place the product in a place with high temperature and light transmission outdoors, so that the product will be oxygen-free. When we properly maintain the silicone button manufacturer and place it in a dry place for ventilation, the silicone button manufacturer will not accelerate the aging speed and reduce the service life.

Silicone products brittle hair reasons how to choose silicone sleeve

Silicone products brittle hair reasons how to choose silicone sleeve

Silicone finished products are famous for their superior elasticity and super high tear strength. Products made of silicone materials have long service life, comfortable hand feeling and flexible texture, which are incomparable to products made of other materials. Therefore, they are also widely used in many fields. In the production process of silicone products, it will be found that silicone finished products will appear brittle, which affects the production, and the brittle silicone finished product in the service life also can not meet the requirements, then, what are the elements of the occurrence of the brittle silicone finished product. First, the structure of the finished silicone product or the design of the mold causes the product to split briefly, and the product structure or the design of the mold is unreasonable, causing the finished silicone product to split briefly during molding. The solution is to modify the structure of the product or the mold to end the improvement, for example, slightly thicken the excessively thin local area, slightly round the right angle, etc. Second, the molding temperature is too high or the curing time is too long, resulting in brittle silicone products, the solution: lower the temperature to control the curing time. Third, the secondary sulfur ventilation is not good or the temperature is too high to form a silicone finished product brittle, silicone products factory solution: carefully adjust the secondary sulfur ventilation and control the temperature. Fourth, the material of silica gel itself and the elements of the glue itself constitute the primary elements of the brittleness of the finished silica gel product. Usually, the brittleness of the finished silica gel product is due to the poor quality of the glue itself and the tear strength cannot reach the request. In addition, many finished silica gel manufacturers now fill the glue with silica powder to reduce the cost in order to reduce the cost, which makes the glue whose original tear strength cannot meet the requirements more brittle. How to choose a good silicone sleeve. 1. Material: It is divided into pure silicone and ordinary silicone. Pure silicone has good toughness and will not turn white when stretched hard, while ordinary silicone rubber products are easy to break, and will turn white when pulled lightly, indicating that there is silicon powder with cheap value added in it, which is shoddy. 2, feel: good feel smooth, poor feel sticky. 3. Appearance: The good color is uniform, the poor surface is rough, the color is different, and even impurities can be observed. 4. Taste: Silicone has more or less peculiar smell, and poor silicone has a particularly strong and unpleasant taste. Secondly, the different molds, mold design is reasonable, fine degree, also different, which laid the silicone sleeve finished product quality, ease of use.

Problems encountered in the production of silicone products

Problems encountered in the production of silicone products

2020-09-25 11:48:51

Silicone products in the process of production and life, is already a very common product, the extensive use of silicone products to our production and life has brought a lot of convenience, silicone is a kind of environmental protection and non-toxic, has many excellent characteristics of a material, then, speaking of this, have you ever thought about what factors will affect the silicone products. One: composition parameters. The health and safety of exported silicone products is a problem that Europe and the United States attach great importance to. This year, it has been found many times that the pre-inspection and sampling inspection of exported silicone products are unqualified. The unqualified health index of exported silicone products requires us to improve the following three reasons and the quality control of raw materials is not strict. Some factories do not pay much attention to the raw materials used for kitchen tableware, silicone raw materials with low quality grade are used for the production of food tools without testing the raw materials, or unqualified colorants and auxiliaries are used for coloring in the production process, resulting in unqualified product hygiene. Two: the production process is not standardized. Due to the particularity of the safety requirements of silicone tableware, food silicone products have very strict requirements on the production process. After the product is formed, it takes enough time to remove volatile substances. In order to pursue efficiency, some factories have not reached enough processing time. Silicone silicone products factory because of its superior reliability, longevity and extreme temperature adaptability and stability and widely used, it will not be deformed, nor will it be damaged under extreme temperature exposure, different from the excellent characteristics of silica gel itself, widely used in life, to provide us with a lot of convenience, then, what are the common problems of silica gel. What are the specific production processes of silicone products. Preparation of raw materials (also called rubber refining, material preparation, etc.): including mixing of raw rubber, color matching, weight calculation of raw materials, etc. Vulcanization molding (also called hydraulic molding): the use of high pressure vulcanization equipment after high temperature vulcanization, rubber products to make silicone raw materials into solid molding. Pifeng (also called processing, removing burrs, etc.): the silicone sleeve products removed from the mold will be accompanied by some useless burrs and hole chips, which need to be removed. at present, in the industry, this process is completely completed by hand, and some factories also use punching machines to complete it. Why is it that there is no acid and alkali resistance and no aging resistance? In the process of making silicone molds, we suggest that customers should not add any silicone oil. If necessary, the amount of silicone oil added should not exceed 5% ~ 10% at most, because the amount of silicone oil added Too much will destroy the molecular weight of silica gel, so the mold will produce no acid and alkali resistance and no aging resistance. 14 years of silicone rubber professional custom manufacturing manufacturers, to provide you with the best products, silicone products factory in dongguan city custom phone: 0769-86652688-808,http://www.dgminz.com/
