How to prevent scorching in common sense of silicone products

How to prevent scorching in common sense of silicone products

2021-02-24 11:50:34

Under normal circumstances, there are many matters needing attention in the production process of mixed silicone rubber. For example, it is common for materials to burn to death, mainly because the reinforcing agent and reinforcing filler mixed in the sealing material fail to control its proportion in the production process. If this material flows into the silicone product molding manufacturer, it is likely to cause the product to be uncured, the product to have poor tensile resilience, and the rubber product to be brittle. Mixing silicone rubber is based on methyl or linear high-polymer polyorganosiloxane (commonly known as raw rubber) containing vinyl groups, with reinforcing fillers, extender fillers and additives to give various properties. The design of the rubber compound should be appropriate and reasonable. For example, the accelerator should be used in various ways as much as possible to inhibit scorching. In order to adapt to high temperature, high pressure and high-speed rubber mixing process, in the formula can also be equipped with the right amount (0.3~0.5 parts) of scorch retarder. 1. The defective product cannot be recycled. If it is not a good product of silica gel, then the company will face scrapping. If we only have a slight adverse effect on the appearance, we can still do repair processing. 2. The screen printing on the silicone products made of silicone can be removed. The silicone products have just been screen printed. Before entering the oven, they can be dipped in a little dust-free cloth screen to wipe some white electric oil. After baking, the screen will be more difficult to eliminate. At this time, sandpaper or electric grinding wheel silicone key press can be used to polish and remove the screen printing. The electric grinding wheel should pay attention to the technique and strength, improper operation method will lead to the use of silicone products processing surface quality wear marks. Production process 3. Silicone products, sealing ring customer samples/drawings → design → customer confirmation → sample opening, proofing → sample confirmation .. confirm purchase contract → open → custom production and manufacturing mold assembly → QA → delivery according to contract requirements. 4, silicone products company packaging production management process, preparation of active materials → mixing liquid silicone → molding → vulcanization → silk screen → spraying → trimming. 5, silicone product surface treatment, spray hand oil, as the name implies is to make the product feel a good feel .. oil spray plus laser carving, silicone package items spray silicone edge silicone products factory, and then the ink layer coloring laser out of the pattern after the surface, color epoxy resin, silicone has been repaired side drop liquid glue to make a pattern, color printing, any color pattern is printed on the silicone material products that can be repaired. The technical process of the silicone key manufacturer can make the silicone sleeve not only beautiful but also more stereoscopic.

What procedures do customers need to follow if they want to customize the production of silicone rubber products? The process flow of the silicone products factory is as follows. The production process is completed from strict production processes such as artwork design, mold opening and glue mixing. 1. The design of the artwork is generally based on the sample size provided by the customer. The silicone key manufacturer uses various three-dimensional drawing and three-dimensional drawing software to make it. If the customer cannot provide the sample, we can charge the customer to complete the drawing according to the customer's request. 2. Opening the mold and opening the seal mold is finished by the mold master on the CNC machine tool of the company according to the designed programming level. Some of the more difficult ones need to be manually discharged by spark machine to exit the mold. Therefore, the mold with higher content of rubber products in manufacturing technology has a relatively longer cycle, and the delivery period is usually 10 days. 3. Color mixing glue, color matching according to the Pantone color card specified by the user, the materials required for the rubber buttons are all environmentally friendly silicone, and the hardness is arbitrarily selected from 30 degrees to 70 degrees. 4. The upper mold is produced. After the mold is installed on the machine and heated to a suitable temperature, the output value of a machine is about 100000 pcs per day. Rubber O-rings are used in hydraulic and pneumatic systems and various mechanical equipment and components. Silicone products are used for sealing under static or moving conditions in specified pressure, temperature and different liquid and gas media. Silicone sealing rings are mainly used for waterproof sealing and preservation of daily necessities such as fresh-keeping boxes, electric rice cookers, drinking fountains, lunch boxes, heat preservation boxes, heat preservation boxes, water cups, ovens, magnetized cups, coffee pots, etc. Silicone key rubber O-ring use and storage attention. 1) Rubber O-rings are generally not reusable. 2) When the rubber O-ring is installed in the groove, be careful not to twist the rubber O-ring. 3) When installing the rubber O-ring, consider coating the sealing medium on the groove and O-ring. 4) The rubber O-ring should not open the original package of liquid silicone when it is not in use, so as to avoid dust or foreign matter on the rubber O-ring, which may cause damage to the rubber O-ring.

Why Silicone Gasket Dark Marks Silicone Gasket Quality

Why Silicone Gasket Dark Marks Silicone Gasket Quality

2021-01-25 14:46:47

Silicone products why there will be dark marks. 1, silica gel raw materials. The raw material properties and product ratios of silica gel products are different from those of silica gel key manufacturers. Therefore, for the understanding of external adverse phenomena, the surface factors are still different according to the distribution ratio of silica and silicone resin in the products. Because the raw materials belong to semi-permeable solid white glue, the mixing uniformity of the mixed rubber and vulcanizing agent depends on the quality of the rubber compound during the mixing process, while the positive rubber products are the above-mentioned reasons. 2, silicone mold. The mold is the core of the silicone product. The material selection on the mold steel occupies the main factor. Secondly, the surface defect in the processing process is probably due to the deformation of the mold caused by the excessive number of rubber keys pressing, which leads to the poor appearance of the silicone product. Secondly, in the finishing process of the mold, the precision of the mold determines the closing line of the product, the self-disassembling edge and the edge wheel angle, etc. How to correctly identify the quality of silicone gaskets. 1. Wear resistance. O-ring silica gel is becoming more and more popular because of its environmental protection performance. To understand the knowledge of silica gel products, one must start with the original silica gel product material. Wear resistance is the ability of the production and molding of silica gel products. The surface of silica gel gasket can suffer from loss. Generally, the surface of silica gel gasket seldom rubs off the silica gel keys on the surface of the product due to external factors, which does not affect the appearance, text and color, and inferior quality silicone products surface characters easy to fall off. 2, elasticity, silicone gasket has good elasticity, sealing ring because of high elasticity is mainly from the movement of silicone molecular chain segments, so in the purchase of silicone products to look at the elasticity of silicone products to judge the quality. 3. Fatigue resistance and heat resistance of O-ring: Silicone rubber has much better heat resistance than ordinary liquid silicone rubber. It can be used almost forever at 150 without performance change. It can be used continuously for 10000 hours at 200. It can also be used in silicone product factories for a period of time at 350. It is widely used in occasions requiring heat resistance, hot water bottle sealing ring and pressure pot ring heat-resistant handle.

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.

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.
