What causes the distortion of silicone rubber O-rings

2021-01-22 16:52:39

During the vulcanization of rubber sealing rings, what are the reasons for the poor performance of rubber sealing rings caused by silicone key manufacturers? For example, the vulcanization working time of rubber sealing rings is insufficient or the vulcanization working temperature is not up to standard, that is, the vulcanization degree is insufficient (also known as sulfur deficiency), and the physical properties of the sealing products are not reached by seals, such as low hardness, low strength, elongation and large deformation, elasticity and other characteristics can not normally play (show the inherent ability) advantages, which has a greater relationship with the degree of sulfur, silicone products silicone raw material rubber products according to the performance can be divided into ordinary silicone and meteorological silicone. The physical property of the rubber sealing ring becomes lower, which affects the rubber material characteristics of the sealing member. The silicone raw materials of silicone products can be divided into ordinary silicone and rubber key meteorological silicone according to their performance. Subsequent observation can be made through the vulcanization curve. If the torque has been on the rise with the increase of time, the hardness of the sulfur-bearing rubber material is larger than that of the positive vulcanization. If the torque has a downward trend with the increase of time. Silicone rubber O-ring distortion refers to the phenomenon of O-ring twisting along the circumferential direction. The distortion phenomenon generally occurs in the dynamic sealing state. Silicone products are mainly used for molded products, such as silicone sleeves, silicone products, silicone tableware, silicone keys, etc. Liquid silicone is mainly used for extruded products, such as silicone nipples, silicone tubes, etc. I would like to tell you the reasons that may cause the distortion and damage of the silicone rubber O-ring. One of the main reasons for the silicone key is that the gap between the piston, the piston rod and the cylinder barrel is uneven, the eccentricity is too large, and the cross-sectional diameter of the O-ring is uneven. Some parts of the rubber O-ring rub too much and twist occurs. Sealing ring. Second, the rubber O-ring with a small cross-sectional size is also prone to uneven friction, resulting in distortion of the silicone rubber O-ring. Third, the deviation of the coaxiality of the sealing groove, the unequal sealing height and the uneven cross-sectional diameter of the rubber O-shaped liquid silicone ring may cause one part of the rubber O-ring to compress too much and the other part to be too small or not to be compressed, thus causing distortion. The cold resistance of the O-shaped ring: the ordinary rubber is delayed to -20 silicone product factory -30, I .e. silicone rubber still has good elasticity at -60-70, some specially formulated silicone rubbers can also withstand extremely low temperatures.

How to make colorful silicone accessories drawing design

2021-01-21 16:51:08

The natural aging and shrinking phenomenon occurred in the production process of silicone rubber products factory. The main problem in raw materials is that organotin in raw materials may conflict with catalyst, reinforcing agent and catalyst. If there is a slight difference in the blending ratio, the silicone key manufacturers with poor curing effect, polysulfide compound polysulfone, urethane or amine-containing substances cannot be saturated. After addition, compound reaction occurs and the whole does not cure, incomplete curing and other phenomena. Everyone knows that silicone products are not as monotonous as before. Seals are in different colors in many ornaments on the market, kitchen supplies, daily necessities and so on in life. This also thinks that many purchasing friends have doubts about the colorful silicone products, and rubber products are afraid of various problems in their color quality, but for friends who don't know much about silicone products, do you know how to color silicone products. Silica gel raw material is originally transparent in color, colorless and tasteless. It is a high living material with strong adsorption performance. It does not conflict with any rubber key material except strong alkali. However, since silica gel raw material must maintain a variety of styles during the production process, it appears that it has many choices. Therefore, silica gel product manufacturers use color masterbatch to add various colors to it to keep its appearance not single. For many silicone accessories, many guests do not know the characteristics of their silicone accessories, and it is definitely not possible to blindly follow the figure. At this time, we need some suggestions. General root silicone products have experience. At this time, we need to combine the silicone products of the articles to be protected with the properties of silicone sleeves to give some suggestions to the guests. In this process, we need a lot of silicone product experience. The surface of the silicone rubbing panel is made of silicone material. This material has high stability and does not add other chemical silicone buttons. We can use it with confidence in our daily life. Each kind of rubbing plate will be different when used in different families. For example, the silicone rubbing plate can only be used in a cage, not in an oven or rubbing pad. Only the silicone rubbing panel can be used in an oven sealing ring. Due to its good heat preservation effect, silica gel can well protect the temperature of food and reduce temperature loss. The food placed in the silica gel container can still maintain the original temperature after a period of time, and will not transmit the temperature to the user. Liquid silica gel is easy to burn. Compared with ceramics, silica gel tableware is most characterized by its fall resistance. There will be no sound when falling on the ground, while plastic tableware can also withstand falling, however, the hardness of the plastic is large, and there may be cracks after the fall.

How to produce silicone products bonding and water transfer printing

2021-01-20 10:10:10

Silica gel itself is a soft material, and its essence is to be molded by viscous liquid glue sealing ring or paste-like solid glue at high temperature. Therefore, the wisest choice for silica gel and silica gel is to use silica gel materials to bond, such as two-component AB glue or one-component RTV glue. At present, silica gel glue commonly used in liquid silica gel is regarded as one-component RTV silica gel glue series, the bonding effect is completely similar to the effect of silicone molding. Usually, some combined glues will appear foggy and white after long-term use. Silicone product factories have poor adaptability to the environment and are difficult to adapt to many environmental conditions. The bonding effect of silicone glue is the same as that of silicone product manufacturers in high-temperature molding and curing. It can be completely welded to the silicone surface and the bonding is relatively tight. Silicone key manufacturers usually have two choices, the first is cold drying, after bonding, natural forming and curing, the second is high-temperature curing after bonding, which can usually be used for different products. If high-temperature baking is not possible, cold drying can be selected, and high-temperature treatment is required. Hot dry glue can be selected for seals. Water transfer printing is used in all walks of life, and silicone rubber products are no exception. In the water transfer printing process, it is mostly used for comprehensive appearance pattern treatment. Therefore, some silicone products or rubber products that need comprehensive color or have more surface coverage can be used. Although the water transfer printing production and processing process is simple, the processing efficiency is very slow, so it only takes advantage of a small number of processing. Compared with other printing square rubber buttons, water transfer printing is a relatively environmentally friendly processing process, and it is also an emerging high-efficiency printing method. It breaks through the limitation of uneven surface that flat printing cannot reach, and is practical. Strong, wide range of use, simple operation, and much favored. Silicone material we have more or less to see a point, it and rubber has always been a kind of soft rubber, but its performance is more environmentally friendly, many friends because of its breakage and bonding problems, so what is the cause of silicone products. In fact, the main reason for the weak glue is the choice of glue. Many consumers just think that there are only a few simple glue, but they do not know that glue is different for different materials and different silicone key bonding methods. There are certain differences, not only 502 glue, so today I will explain to you how to choose the glue for silicone products.

How to choose multicolor silicone spoon product process

2021-01-20 09:52:42

The choice of technology, due to the different structures and processing technologies of different silicone spoons at present, there are pure silicone materials, silicone package hardware and nylon plastic in silicone package silicone products factory to improve the support strength. For this choice, it is up to you to choose where you need to use it. For example, if it is only a silicone spoon for infants, you can choose pure silicone materials. For cooking, it is recommended to use hardware package glue with stronger strength silicone key manufacturer, if it is only for soup and rice, it is recommended to use nylon silicone spoon. In order to meet the user experience of consumers in the silicone industry, multi-color products have always been relatively popular products. However, for the control of process and cost seals, many silicone product manufacturers will also choose some cost-saving and simple processing methods when producing two-color multi-color products. The relatively simple two-color and three-color silicone products basically adopt the secondary molding processing square rubber product type. This type of method mainly cures the secondary color body first when the silicone product processing factory produces, fixes the color sub-parts into the main color mold cavity, and carries out secondary vulcanization after putting the main color rubber material into the main color mold cavity. The produced product is not much different from the rubber button dropping process, however, this method also depends on the structure of the product and the color system. If the product is too small to place the color K, too many colors and complicated operations will affect the efficiency. Therefore, there is no big problem in making a few simple colors in this process. Among the living and dining tools, spoons are inevitable kitchen utensils. At present, the main materials of common spoons are stainless steel, wood, plastic, etc. In addition, there are also silicone materials that many consumers choose to use. Silicone silicone products are currently a popular material. They are used to make spoons and are used for children's tableware, which is no exception in family daily use, so you should buy a high-quality silicone spoon, its brand in the end that silicone button is good. The premise of choosing a good silica gel product is to choose a high-quality silica gel processing factory. Silica gel belongs to soft environment-friendly tableware. The most important factor acting on spoons is safety and environmental protection. Therefore, the requirements for materials are naturally heavy on sealing rings. Ordinary silica gel and gas phase silica gel have different fineness, and different fineness leads to differences in stretching, rebound and various characteristics of materials, liquid silicone silicone spoon must be safe and environmentally friendly. In terms of material, it needs to reach food grade at the lowest, so pure gas phase hair gel is the most basic choice for material.

Silicone products why will appear dark lines

2021-01-18 15:05:40

The newly trained raw materials should pay attention to the temperature adjustment during molding. If the temperature is insufficient, stripes and even unripe phenomena will appear after the silicone products are molded. Therefore, the temperature should be raised every time they are molded. The silicone raw materials will also have problems after the silicone products factory is over-vulcanized. The raw materials themselves are transparent and vulcanized at high temperature after adding color masterbatch, and there is no problem at normal high temperature. However, if the vulcanization time is too long, with the increase of temperature, the color masterbatch will have a slight scattering phenomenon of silicone key manufacturers in the raw materials, so there will also be color deviation phenomenon inside the product and dark marks. Therefore, it is not advisable to have too high temperature in the production process, and the temperature is too low to keep up with it. In this way, the dark mark phenomenon of the seal of the product can be solved and the customer is more satisfied. Silicone strip in addition to good sealing, there are many characteristics of quite good. 1. Silicone sealing strip has good sealing performance, high temperature resistance, weather resistance, aging resistance, shockproof and waterproof, and can fit various rubber products with smooth surface materials. 2. Self-adhesive tape, better sealing performance, long-term use of high temperature resistant glue does not fall off, environmental protection and safety, good insulation, high temperature resistance, small compression deformation, strong resilience, and non-toxic. 3, heat resistance: rubber button silicone rubber has much better heat resistance than ordinary rubber, can be used almost forever at 150 degrees without performance change, can be used continuously at 200 degrees for 10,000 hours, at 350 degrees can also be used for a period of time. We often encounter many problems in the production process of silicone products. What gives us a headache is the quality of the products. The quality problems can be divided into many types, including artificial problems, natural phenomena, mold problems, raw material problems of silicone products, etc. There are too many and too many problems. Then we find that the products have stripes and dark lines. Then the following small series will tell you about the cause analysis of dark lines in silicone products. We carry out glue mixing process. Due to mechanized silicone key adhesive, uneven mixing will occur more or less. After adding vulcanizing agent and color masterbatch, the mixing time is too short, resulting in uneven original internal color and half dark and half light color. Therefore, it is important for glue mixing personnel to remind that the first process is required by sealing ring, and too long time after glue mixing will also lead to product quality problems in silicone products, generally, the material that is placed too long has a great influence on the hardness of the product. It should be used in time, and it should not be placed too long for one to two days. Liquid silica gel.
