The relationship between transparency and silicone tube quality

For the transparency of the medical silicone tube, many friends have questions, is not the higher the transparency of medical silicone tube that the better the quality? Many of you think this because the silicone tube we see in the usual drip is very transparent. But that's because its wall thickness is relatively thin, silicone tube is smaller, so it will look like a very transparent feeling. In fact, medical silicone tube is generally translucent with some foggy, not as we thought as highly transparent, because the color of silicone rubber itself is translucent, such as the production of the high transparency silicone tube, will change the physical structure of silicone rubber itself, which makes the parameters have changed, and ultimately affect the life of the medical silicone tube, although theoretically can be very transparent, this is unrealistic, which is determined by the nature of raw materials by the silicone rubber. But compared to ordinary silicone tube, medical silicone tube for medical devices with high transparency, odorless, excellent anti-aging performance, high tear, excellent resilience, permanent deformation, resistance to weak acid and alkali, high and low temperature, etc., can be in -50-250 degrees normal work, has excellent insulation and permeability, the general use of imported silicone raw materials or platinum silicone tube as raw material. For the silicone tube, transparency is not the standard for the quality of the characterization of its good or bad, but to see if the production process and products of the silicone tube in line with its use parameters.

Is Silicon brittle or malleable?

Why does silicone become "brittle"? In life, some silicone products in the use of the process are easy to become brittle, brittle silicone products can no longer be used, so many people feel a headache. In fact, the root cause of the brittle silicone products is the nature of the silicone material, after the silicone products reach a hardness of 60 degrees or more. Its resistance to tearing and elasticity, etc. will plummet, resulting in silicone products become brittle! So if you want silicone products to become less brittle, find a way to make them below 60 degrees hardness. Of course, there are some technical production process can affect the factors of silicone brittle. The following is to say that the production of silicone products will be heated to a certain temperature during the production process, but if the temperature control is not good or heating time is too long, will lead to brittle silicone products, in addition, in the use and storage process, can not maintain good ventilation, or secondary vulcanization for too long will also lead to this phenomenon, and the most important is the silicone products themselves material problems, if the material is not good, can not reach the tear strength, so the silicone products will become very fragile. In addition to these, silicone products become brittle with the design of the mold also has a relationship, if the mold design is unreasonable or the production structure of which is unreasonable, this may lead to silicone products, in the production process of fracture mold, if this phenomenon really occurs, the production of silicone products will naturally become brittle, so before the production process, we must try to improve the processing of mold structure. This is one of the main reasons that lead to brittle silicone products, in addition in the process of use, if the ambient temperature is too low, or use for too long, has been the aging phenomenon, will also lead to brittle silicone products, so for silicone products, after a period of time in the use of the product aging should be replaced in a timely manner.

Comparison of the silicone market between China and foreign countries

There is a certain gap between the development of the silicone products industry in China and some European and American countries, first of all, the development of the silicone industry in China in the There is a certain gap between Europe and the United States in terms of time, and also a lack of certain technology in terms of R&D experience, so it is not the same as some other countries. There is a certain gap in comparison. In the special adhesive and high-performance adhesive, our products appear a lot of deficiencies. Silicone products Secondly, now the competition in the silicone products industry also determines the severity of many manufacturers, capital flow difficulties, excessive competition, customer requirements Can not meet, product homogeneity is serious, raw material prices continue to rise, leading to the phenomenon of the closure of many of our domestic manufacturers. In some industrial manufacturing industries and the medical industry most of the use of imported silicone production, while domestic silicone products are mainly used in low-end no Special requirements above the product. But in recent decades, China's silicone products in the annual growth rate of 8%-15%, more than many countries in general economic growth rate, silicone rubber products in our country is more and more widely used in our lives, industrial manufacturing, major industries have, the number and variety of products are also constantly increasing, the use of the field is also constantly expanding, the number of silicone products manufacturers in China is now nearly far beyond the number of foreign countries. According to statistics, the number of silicone products manufacturers in China has nearly exceeded 1000 manufacturers, so now the domestic silicone manufacturing industry. The silicone products industry is relatively small, and many of the products produced are exported. However, some manufacturers who have stood firm in the industry for a long time for the domestic demand is also developing well. There are many companies to choose from in the country as well.

How to calculate the quotation of silicone rubber mold?

How to calculate the silicone mold quotation? The process is different from the rubber, plastic and other industries, processing methods and processes are more complex, in addition to personnel, machinery, raw materials, and molds, etc. Need for different processes and special processes aside, as you know, need to consider all aspects of price accounting to ensure that the product is processing And the right fit for production. 1. When it comes to price accounting for silicone, first and foremost, the weight of the product is of utmost importance. In the silicone rubber products industry, no one will quote accurately if the product does not have a weight, so many inquiries, and customers need 3D Drawings or samples to calculate the weight of the product when they need a quote. For calculating the weight of the product, the product volume x silicone density is usually used. The silicone rubber products industry is known to have a density of 0.0012, so if you multiply the density of the silicone by the volume of the product, if the product The weight of the silicone is not the weight of the silicone, then the product can not only determine the production of silicone material, so the density of the silicone can not only determine the density of The weight of the product and you can also know if it is of silicone quality. 2. After the weight calculation is completed, compare the first mold of the product with the first mold of the mold to see the weight of the product and the burr of the Weight, quantity of raw materials, curing time and smooth processing, the above calculations complete the profitability of the silicone products manufacturer. Ensure that the product can be processed at a reasonable price, so the quoted price of the product is not only related to the weight, but also to the factors of the machine and the Human factors related, the intermediate production process is the key to solve major product quality problems. Therefore, it is not only under the growth and operation of the machine and the precision of the tooling but also to enhance the quality of the operating techniques and the quality of the operators and quality control personnel to meet certain requirements.
