現(xiàn)在社會的發(fā)展越來越快，時代進(jìn)一步的進(jìn)步，也造成了市場化經(jīng)濟(jì)的發(fā)展。越來越多的人開始從事管材事業(yè)，但是管材事業(yè)制作不完善的話就會出現(xiàn)很多的問題，管材結(jié)構(gòu)化就是一個重要的問題。為什么在制作過程中會出現(xiàn)結(jié)構(gòu)化呢？那么硅膠管結(jié)構(gòu)化是什么呢？發(fā)生之后又要怎么解決呢？

硅膠管的生產(chǎn)結(jié)構(gòu)一般來說就是把天然硅橡膠進(jìn)行加工處理，在按照需求的配方進(jìn)行加工，最后加入合成劑和其他材料通過煉膠機(jī)和磨具的合成，最后形成一根根的管材。但是，一般工廠在生產(chǎn)管材的時候就有可能出現(xiàn)管材結(jié)構(gòu)化。

管材的結(jié)構(gòu)化就是在生產(chǎn)過程中采用白炭黑不強(qiáng)的硅橡膠在儲存過程中出現(xiàn)變硬的情況，這會造成橡膠的可塑化降低，從而失去加工的工藝性能。這種現(xiàn)象就稱為“管材結(jié)構(gòu)化”。

原因

1、最普遍的說法就是在氣溫的影響下，表面的火星硅醇基與生膠分子產(chǎn)生化學(xué)作用，發(fā)生縮合，從而就會導(dǎo)致橡膠的變硬，塑性降低。

2、白炭黑表面的基原子與生膠分子產(chǎn)生作用生成氫鍵，乃至化學(xué)結(jié)合。使硅橡膠內(nèi)的硅氫氧轉(zhuǎn)變?yōu)榧俳宦?lián)或微交聯(lián)的固性狀態(tài)，這也就造成了硅橡膠的固化。

解決方法

1、在硅橡膠中家住“結(jié)構(gòu)化控制擠”，這是生產(chǎn)中最常見的解決方法了。

2、對白炭黑表面進(jìn)行處理，從而防治白炭黑和生膠發(fā)生作用。

硅膠是一種環(huán)保無害的材料，它制出來的硅膠管也是及其環(huán)保的一種管材，人們在使用時要合理使用。

Now the development of society is faster and faster, and the further progress of the times has also led to the development of market-oriented economy. More and more people begin to engage in pipe industry, but there will be a lot of problems when the production of pipes is not perfect, and the structure of pipe material is an important problem. Why do we have structural problems in the production process? So what is the structure of silicon HOSE? How will it be solved after the occurrence?

In general, the production structure of the silicon rubber tube is to process the natural silicone rubber. It is processed in accordance with the required formula. Finally, the synthetic agent and other materials are added through the synthesis of the rubber machine and abrasive tools. Finally, a root pipe is formed. However, when a general factory is producing pipes, it is possible to have tube structure.

The structure of the pipe is the condition that the silica rubber is hard in the process of production, which will cause the plasticity of the rubber to be reduced and the processing performance will be lost. This phenomenon is called "tube structure".

Reason

1, the most common saying is that under the influence of temperature, the surface of the Martian silanol group has a chemical reaction with the raw glue molecules, and the condensation occurs, which will lead to the hardening of the rubber and the reduction of the plasticity.

2. The base atoms of silica surface react with the raw rubber molecules to form hydrogen bonds and even chemical bonds. The siloxy hydrogen in silicone rubber is changed into a pseudo crosslinking or micro crosslinking solid state, which results in the solidification of silicone rubber.

Resolvent

1, in the silicone rubber home "structured control crowded", this is the most common solution in production.

2. The surface of white carbon black is treated to prevent the occurrence of silica and raw rubber.

Silica gel is an environmentally friendly and harmless material. The silicone tube made of it is also a kind of environmental protection tube. People should use it reasonably.
