Production of silicone products grinding method is not important

Production of silicone products grinding method is not important

2021-02-23 09:26:18

It is very important whether the products can be ground by seals. Many products are not completely ground due to structural problems or worn out due to too serious grinding. This phenomenon is usually aimed at products with relatively small products and corners, such as facial cleanser brushes. If the brush is too fine, the brush head may be ground flat through grinding of grindstone rubber products, followed by right angles or dead corners, where the stone is too small to grind into the grindstone, local burrs and parting line problems arise. Grinding machine setting, the length of time and the speed of rotation, different silicone products use rubber keys with different rotation speeds and times. If the time is too long for a relatively small type of product, it is likely to lead to wear or sanding. If it is a large product, the time is too short to grind the core position. In addition, it also depends on the workmanship of the product. At present, there are many kinds of silicone products, which can basically meet the production of various types and styles of products. In order to let customers know which production mode their products are suitable. Molding: This is a very common production process of traditional silicone products. The main silicone products are completed by cooperating with the mold. The shape of the silicone product is determined by the mold. The molding process is usually to heat the temperature in the mold, and then place the silicone raw material into the vulcanizing agent for vulcanization. After vulcanization, pressure is applied to the table to form the raw material. Silicone key injection molding process: this process requires a higher quality, is a combination of silicone and plastic liquid, because the process is mainly for the higher requirements of silicone products, so it is usually only used for baby products, medical supplies production. Extrusion molding: refers to the way to extrusion molding sealing silicone products, usually extruded silicone shape is long, tubular, can be arbitrarily cut, can be used for strip, tubular silicone products. Calendering process: the film processed by calendering has obvious difference in the physical and mechanical properties of the vertical and horizontal liquid silica gel, which is called calendering effect. The pressure effect is caused by the macromolecules and needle-like and sheet-like complexes in the rubber compound under pressure and oriented along the pressure direction. Therefore, it is usually used for larger products, such as silicone sheets, silicone plates, etc. I don't know if you have noticed a problem in the silicone product factory. Many handicrafts have been made without any defects and can't find any defects. There are two main phenomena in this problem. The first is that the defects of the products have been avoided in the invisible position in the design process, while the other one of the silicone key manufacturers has achieved the complete effect through grinding or post-process treatment, in the silicone products industry also has this phenomenon, through the external process to solve the appearance of the problem, this process is often said "grinding processing".

What is the reason for the appearance of odor silicone products

What is the reason for the appearance of odor silicone products

The peculiar smell of silica gel products is also related to sulfur (chemical symbol: S) agent. The composition and formula of vulcanizing agent may also lead to peculiar smell of products. Moreover, the proportion of this reason is relatively large. The factory element of sulfur silica gel products itself has taste. If the process is not handled properly, there may be odor, which is naturally unacceptable to ordinary users. Friends who know some silicone products should understand that it will feel soft. Some silicone key manufacturers will harden, because the hardness of silicone determines its physical properties. However, for friends who use silicone for the first time or friends who need to make silicone products for the first time, the hardness of silicone is not well understood, and there is uncertainty about what kind of hardness seals need. Method 1: the use of relatively high hardness of silica gel and relatively low hardness of silica gel according to a certain proportion of mixed deployment, generally more than 50 degrees of silica gel and more than 30 degrees of silica gel mixed deployment, in the harder silica gel, the hardness of silica gel rubber products is about 40 degrees. Method 2: We can usually use silicone oil to reduce the hardness of silica gel, but in practical application, if the ratio of silicone oil can destroy the molecular weight, tear resistance, tensile strength, etc. of silica gel, the corresponding deterioration of rubber keys will occur, affecting the life of silica gel molds. In addition, too much silicone oil will make silicone rubber molds easy to deform, so the ratio of silicone oil to silicone oil is generally not more than 5%, try to add silicone oil with higher viscosity. If the silicone oil content exceeds 5%, use a small amount to determine whether it is available. Now with the continuous improvement of the process, the application of silicone products in life is becoming more and more extensive, but it is worth mentioning that there are often some odors, many people feel puzzled, do not know what to do, in fact, this is related to production, make silicone products and so on, O-ring silicone because of its environmental protection performance and more and more popular, to understand the knowledge of silicone products, we must start with silicone raw materials. Silicone products odor reasons:. If it is the problem of silk screen printing raw materials, it is natural to consider how to make the taste of raw materials smaller or even disappear. Usually, the products can be scattered in the production process and blown with a large fan, which can effectively reduce the taste of silicone products. Secondly, the peculiar smell of silicone products is also related to hand-felt oil. Perhaps this problem will make people feel surprised. Some hand-felt oil originally does not have a very heavy smell, but after the oil injection operation is completed, it will produce a very heavy smell. If it is scattered or left for a period of time after blowing, it is necessary to consider changing the type of hand-felt oil in the case of liquid silicone.

What causes the distortion of silicone rubber O-rings

What causes the distortion of silicone rubber O-rings

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 produce silicone products bonding and water transfer printing

How to produce silicone products bonding and water transfer printing

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 understand the silicone products non-toxic harmless, silicone products high temperature, the advantages of long service life in the life of the use of silicone products factory more and more widely, but a lot of people on whether the silicone toxic doubt. 1. Liquid silica gel: silica gel is a highly active adsorption material and is an amorphous substance. Its chemical molecular formula is mSiO2 · nH2O. Silicon is a chemical element of a silica gel key manufacturer and is also a rich element in the earth's crust. Its compounds normally form sand, rock formation and glass. Silicone is considered to be a suitable material for implantation into human body. All human bodies of seals have some silicone. 2, curing agent: there are two kinds of curing agent, one is the platinum curing agent of addition type silica gel, the other is the organic tin curing agent of condensation type silica gel, platinum curing agent is non-toxic and tasteless, and organic tin curing agent is a little smelly rubber products. 3. Addition silicone: it is a two-component addition silicone material, which can be cured at room temperature or heated. Silicone can be used for a long time and maintain its soft and elastic properties of rubber buttons in the temperature range of -65 C- 200 C. It has excellent electrical properties and chemical stability, water resistance, ozone resistance, weather aging resistance, non-corrosive, physiologically inert, non-toxic and tasteless, low linear shrinkage, easy to operate and other characteristics, more used in food, medical and other aspects. I don't know if you have heard of the silicone strip, or why it is used. I don't know in which aspect it is applied. Under the action of sewing equipment, it is combined with the cloth to complete the installation of a textile picture, which plays the role of uniform and crisp silicone products. Of course, it is also used that the cloth is slightly soft and can produce a certain degree of stretching adaptation. What details should be paid attention to when using the silicone strip. When using, we should pay attention to these matters: silicone silicone key strips and rubber strips should have moderate flexibility and width, and cannot be cracked and difficult to take off the needle during sewing (need to be sealed when stored for a long time, and the opening is easy to age and become brittle for a long time). 1. The inside is in the shape of a U, and the cut cloth edge of the sealing ring can be put in directly, which is very easy to sew. 2. The exterior is beautiful and easy to insert into the side groove. Because the silicone strip wraps the cloth edge, whether you are a hot cloth edge or a cold cut cloth edge, the burrs are covered with liquid silicone, which is beautiful and classy, wraps the cloth edge, and is easy to insert. Into the side groove, saving a lot of time and labor.
