Description
Technical field
The utility model relates to a kind of process equipment of polytetrafluoroethylplastic plastic elbow.
Background technology
Polytetrafluoroethylene (PTFE) (be called for short PTFE or F4) is one of corrosion-resistant material in the world today, except that molten alkali metal, element fluorine and chlorine trifluoride, and the almost corrosion of all chemical mediators of ability.And also have high temperature resistant (250 ℃), do not adhere to other any material, be difficult for aging grade for excellent properties again, products such as steel lining PTFE anti-corrosion pipeline and equipment are all made in countries in the world with it.In the fluoro-containing plastic series of products, PTFE is that performance is best, the kind that cost of material is the most cheap, but its difficulty of processing maximum, because the plasticization temperature of PTFE is up to 380 ℃, be exactly under this high temperature, still viscosity is very big for it, does not have mobile, needing very high pressure exists simultaneously, could moulding, so the technology of general plastic shaping (as injection moulding etc.) all inapplicable to it, just more difficult for the goods processing of complex-shaped for example elbow and so on.In decades, PTFE elbow-making method has only two kinds in the world, and a kind of is " isotactic pressing " (having another name called shaped by fluid pressure or rubber bulb method), and the concise and to the point process of this method is, put rubber bulb in the middle of the elbow outer steel shell, fill up the PTFE resin between the two,, rubber bulb is pushed to the box hat inner surface again with water filling supercharging in the rubber bulb, until PTFE is pressed solid till (still raw material), then water is bled off, take out rubber bulb, also it will be placed on the sinter molding of heating in the stove at last.Second kind is cried the moulding of winding method, this method need have the mould of stainless steel bend, the PTFE strip is twined on mould back and forth,, outside it, tie up the upper glass fabric strip again to desired thickness, then workpiece is put into the stove sinter molding, after the demoulding, the PTFE elbow, this elbow is served as a contrast in the elbow box hat, the two ends flange, F4 lining elbow product.But above two kinds of methods processing is all pretty troublesome, and producing an elbow all needs seven, eight hours,
Summary of the invention
