硅胶管粘度软化与催化到什么程度


处理高粘度硅橡胶,高粘度硅橡胶弹性体的处理包括五个步骤:磨软化和催化,准备预成型件,挤压或模压,硫化,和整理。

电缆公司年度工作总结The treatment of high viscosity silicone rubber and high viscosity silicone elastomer consists of five steps: grinding and catalysis, preparation of preformed parts, extrusion or molding, vulcanization, and finishing.


软化和催化,在高稠度硅氧烷橡胶弹性体为在任一挤出或模塑应用中使用的处理的初始步骤是磨软化和催化。这个程序撤消任何“绉硬化”已存储在库存的供应商或制造者期间发生的弹性体。研磨也使用制造者以过氧化物催化剂添加于自由基固化的弹性体,如果需要的话,或混合的加成固化的弹性体的两个部分在制造前。

电缆公司年度工作总结Softening and catalysis, the first step in the processing of high consistency silicone elastomers for use in any extrusion or molding applications is grinding softening and catalysis. This procedure canceling any elastomers that "crepe hardened" has been stored in the supplier or manufacturer of inventory. The grinding is also used by the manufacturer with a peroxide catalyst added to the free radical cured elastomer, and two parts of the added solidified elastomer are before the manufacture, if needed.

硅胶管粘度软化与催化到什么程度


铣削和催化不仅劳动强度大,而且需要使用双辊轧机,其成本约为60,000美元购买和安装的。该弹性体是通过轧机多次传递,直到复合材料是均质的,则在作进一步处理片形式去除。

Milling and catalysis are not only labor intensive, but also require the use of twin roll mills, which cost about $60000 for purchase and installation.  The elastomer passes through the mill several times until the composite is homogeneous, and is removed in the form of further processing.



1、制备预制:一旦高稠度弹性体被完全配合,在制造过程中的下一个步骤是预型件的制备。这不要求特殊的设备,但是非常劳动密集的,特别是在本质上是几乎连续的大批量应用。用于挤出和注射成型应用,该预成型件是通过切割弹性体片材切成条,其用于喂挤出机简单地制备。转移模塑操作中,预型体典型地切用模切机成,将适合在多工位压力机的转移储层的插头。对于压缩成型的应用中,过程是稍微复杂一些,因为预成型件必须在最终的部件的基本几何结构进行切割。

电缆公司年度工作总结1. Prefabrication: once the high consistency elastomers are fully matched, the next step in the manufacturing process is the preparation of the preform. This does not require special equipment, but very labor-intensive, especially in essence, is almost continuous mass application. For extrusion and injection molding applications, the preform is cut into strips by cutting elastomer sheets, which are used for simple preparation of extruders. In the transfer molding operation, the preform is typically cut into die-cutting machines, and the plug is suitable for transferring the reservoir in the multi station press. For compression molding applications, the process is a little more complicated, because the preform must be cut in the final part of the basic geometric structure.



电缆公司年度工作总结2、挤压:对于高稠度弹性体,挤出是使用单螺杆挤出机完成。预成型带被馈送到从辊进给轮到挤出机机筒的挤出机,和弹性体是通过一个模具和心轴组件挤出形成所需的轮廓。另外,也可以进行与高稠度硅氧烷弹性体支撑挤压。这是通过一个十字头组件装配在挤出机中,通过在支撑几何穿过十字头,并在它挤出一层硅橡胶的实现。

2, extrusion: for high consistency elastomers, extrusion is done with a single screw extruder. The preform belt is fed to the extruder from the roller feed wheel to the extruder barrel, and the elastomer is extruded through a mold and spindle assembly to form the desired contour. It is also possible to support extrusion with high consistency silicone elastomers. This is done through a crosshead assembly in the extruder, through the support geometry passing through the crosshead and extruding a layer of silicone rubber.



电缆公司年度工作总结适合于各种行业的应用的挤出机的成本大约是10万美元,包括安装。然而,大多数挤出系统制造者装备他们的机器用激光微米和反馈控制器以监测产品质量,增强了显著到设置挤压工艺的成本增加。另外,挤出可以考虑劳动密集的,因为它需要操作者在任何时候都存在,以确保该挤出机具有弹性体的恒定供应,运行正常。

The cost of extruders suitable for various industries is about $100 thousand, including installation. However, most of the extrusion system makers are equipped with their machines using laser microns and feedback controllers to monitor the quality of the product, enhancing the significant increase in the cost of setting the extrusion process. In addition, the extrusion can be considered labor intensive, because it requires the operator to exist at any time to ensure that the extruder has a constant supply of elastic body and runs normally.



电缆公司年度工作总结3、成型:高粘度硅应用随所用的成型设备的类型。传递和注塑成型工艺需要操作人员来加载弹性体进入设备和脱模成品零件。对于压缩模制,操作人员必须放置在各模具所有单个空腔预型件。因为具有高粘度弹性体所采用的相对缓慢的固化周期的,它有可能为所述模具具有大量空腔。安装转让或注塑机的成本大约为1000至2000美元每吨的夹紧力。压缩成型机是相当便宜。

3, molding: high viscosity silicon application with the type of molding equipment used. Transfer and injection molding processes require the operator to load the elastomers into the equipment and the moulded finished parts. For compression molding, operators must place all single cavity preforms in each mold. Because of the relatively slow curing cycle used by high viscosity elastomers, it is possible to have a large number of cavities for the dies. The cost of installing the transfer or injection molding machine is about 1000 to 2000 dollars per ton of clamping force. The compression molding machine is quite cheap.



4、硫化:挤出产品的硫化通常实现了与热空气硫化炉,或HAVS。这些HAVS是在水平和垂直配置。在水平模式中,挤压型材通过烘箱,热空气被强制在挤出物以引发硫化机理铺设在一个连续带通过。在垂直炉结构中,HAV配备有变速鼓在顶部通过烘箱,在那里它被固化向上拉动挤压型材。一个典型的HAV炉的成本大约是3万美元。其他类型的就业硫化炉包括辐射热烤箱和蒸汽烤炉高压灭菌。

4, vulcanization: vulcanization of extruded products is usually achieved with hot air vulcanizing furnace or HAVS. These HAVS are configured horizontally and vertically. In horizontal mode, the extruded profiles are passed through the oven, and hot air is forced on the extrudate to initiate the vulcanization mechanism in a continuous band. In the vertical furnace structure, the HAV is equipped with a variable speed drum at the top through the oven, where it is solidified upward to pull the extruded profiles.  The cost of a typical HAV furnace is about 30 thousand dollars. Other types of vulcanizing furnaces include radiating hot oven and steam oven for autoclaving.



5、整理:整理所需的程度取决于具体的应用。对于挤塑方法,精加工涉及视觉检查和切割管材的成特定长度。如果管子已经固化用过氧化物,自动整理处理也需要一个烤箱后固化副产物,以除去过氧化物。用于模塑应用,精加工包括所述模制零件的修整或修边,往往采用模切机械以从较大的模塑片材切成各个部分,以及任何烤箱后固化是必要的。除了浪费材料,高浓度有机硅整理是劳动密集型的,并且需要额外的设备,如烤箱和模切机。然而,这种设备是相对廉价购买。

5, collate: the degree of sorting depends on the specific application. For extrusion methods, finishing involves visual inspection and cutting of pipes into specific lengths. If the pipe has been solidified with peroxide, the automatic finishing process also requires a curing by-product after the oven to remove peroxide. For molding applications, finishing or trimming of the moulded parts is usually made of die cutting machines to cut into parts from larger plastic sheets, and it is necessary for any oven to be cured after curing. In addition to wasting materials, high concentration organosilicon finishing is labor-intensive and requires additional equipment, such as oven and die-cutting machine. However, this device is a relatively cheap purchase.
