Precautions for plastic seals

Precautions for plastic seals


Now the function is getting worse and worse. The aging mechanism is not the opposite. Among them, thermal (light) oxygen aging is a common and fundamental way of aging EPDM seals. 1. Fatigue aging Fatigue aging of EPDM sealant strips means that the molecular structure of EPDM sealant strips undergoes changes under the influence of certain frequency and periodic stresses. The aging scene presented is the result of the activation of two secondary elements, namely force and heat (due to


With the development of society, plastic sealing strips have become a new type of plastic that is extremely important for safety, environmental protection, durability and aesthetics, and provide a new choice for a new generation of high corrosion-resistant plastic sealing strips. The appearance is not high, it is easy to break, and the safety is not high. The characteristic of odor is that its porous structure and outer layer are smooth and smooth. In addition to maintaining the excellent performance of the profile, the plastic sealing strip also has certain anticorrosion and corrosion resistance. In the 21st century, in the continuous development of new plastic seals, solvent-free products are the mainstay, and the number of solvent-free components of plastic seals has reached more than 3,000. Due to the complex production process and professional production process, the development of plastic seals will surely Various plastic sealing strip companies create value in order to maintain their quality in a constantly changing environment, and have a crucial role in determining the parameters. Classification of plastic sealing strips: aluminum alloy sealing strips, stainless steel sealing strips, pvc sealing strips, pp plate sealing strips, pe high temperature resistant soundproof sealing strips, pe porous acid resistant hollow plug materials, hot melt adhesive sealing strips, etc.


1. There are aluminum alloy sealing strips. Because most of the adjacent parts are directly pasted on the parts, the installation task is heavy and the workload is large. Not only is it inconvenient to install, but it is also easy to enter the dust, but the thicker metal materials will also have A large amount of rust is a solvent-free plastic seal, which has the advantage of not being easily damaged. 2. Due to its light weight and easy processing, stainless steel sealing strips usually have good lubricity and easy cleaning between the sealing surface and any end surface (especially the end surface is acid-resistant and other substances). A popular profile. At the same time, it also has the functions of anti-corrosion and anti-corrosion, so it has been widely used in the manufacture of metal materials. The number of sealing strips is very small, and it is extremely widely used. It is specially designed for installation and decoration. The durability and corrosion resistance of the sealing strips cannot be ignored.


In particular, the role of the environment resistant to solvents, oils, and moisture and heat media, plastic seals are an effective material. 3. The production process of copper, iron, copper, steel and aluminum alloy sealing strip sealing strip is to input 250v, 300v, 350v and other electromagnetic discharge into the steel ingot of the sintering machine, and use the sorting press and mixer to adjust the pressure to 150 ~200kpa. Copper sealing strip is usually used as auxiliary sealing material in the belt and molecular polymer fiber, and then refined by diluting alumina. It uses red copper sealant to avoid welding, which is not only better than stainless steel, but also can be made into a sliding support , It can also be used to support the strength of plastic clamps. Copper and steel sealing strips have very good strength and toughness, and are also a kind of sealing and decorative materials. 4. The preparation and transportation of metal, plastic, metal powder, etc. has good performance and good fusion with steel. Compared with various metal materials, in addition to novel advantages, we must pay attention to corrosion resistance and wear resistance, which are other Unmatched by similar sealing materials. Metals mixed with carbon generally do not produce argon gas, and are easy to burn in industrial production.


Therefore, dense sealing materials are widely used in industry.


5. Large-area construction plastic materials using plastic seals. It utilizes the characteristics of thermal deformation and crystallization, and has excellent flexibility within a certain range.

It can be used forever without performance change; it can be used continuously for 10,000 hours at 200 degrees; it can also be used for a period of time at 350 degrees. 9. Weather resistance: Ordinary rubber degrades rapidly under the action of ozone generated by corona discharge, while silicone rubber is not affected by ozone. And for a long time under ultraviolet and other climatic conditions, its physical properties have only changed slightly. Rubber edging is a copolymer of ethylene, propylene and a small amount of third monomer non-conjugated diene
