Abstract
The invention relates to a white polytetrafluoroethylene pipe with a colored sign line and a manufacture method thereof. For the white polytetrafluoroethylene pipe, the colored sign line is formed along the axial direction on the peripheral surface of the white pipe wall. With the white polytetrafluoroethylene pipe with the colored sign line and the manufacture method thereof, the white polytetrafluoroethylene pipes can be completely differentiated by using sign lines of different colors, when a plurality of white polytetrafluoroethylene pipes are centrally used for conveying different fluidized media, an operator can not only directly observe the change condition inside each pipe from the outside, but also can effectively differentiate different types of fluidized media according to the colored sign lines, therefore, the white polytetrafluoroethylene pipe is convenient and practical. In addition, the manufacture method can also be used for manufacturing the pipes of pipe walls and sign lines of different colors.
Description
Technical field
The present invention relates to a kind of tubing and processing technique thereof, particularly relate to a kind of white polytetrafluoroethylpipe pipe and manufacture method thereof that has colored sign line.
Background technique
Teflon is a kind of chemical raw material with excellent high and low temperature resistance and chemical stability, excellent electric insulating energy, non-adhesive, weatherability, flame retarding and good self lubricity, therefore obtains extensive use in fields such as chemical industry, oil, weaving, electric, medical treatment and machineries.Polyfluortetraethylene pipe is to adopt extruding method to make with teflon as raw material, and main three will be used for conveying gas or liquid medium.Polyfluortetraethylene pipe color commonly used at present is more single, even be pure white, or has different colors.Because the tube wall of white polytetrafluoroethylpipe pipe is transparent, therefore can be easy to from visual observation to its inner liquid or gas situation of change, and the polyfluortetraethylene pipe that has a color can't be accomplished.But under some occasion, when needs concentrate use to carry different flowing mediums many tubing, when also needing to observe directly from the outside situation of change of every tubing inside and active zone separate different types flowing medium simultaneously, existing polyfluortetraethylene pipe all can not satisfy this requirement.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of situation of change that can either observe directly tubing inside, can concentrate the white polytetrafluoroethylpipe pipe that has colored sign line of effectively distinguishing different interior medias when using again.
Another object of the present invention is to provide a kind of above-mentioned manufacture method that has the white polytetrafluoroethylpipe pipe of colored sign line.
In order to achieve the above object, the white polytetrafluoroethylpipe pipe that has colored sign line provided by the invention is in axial direction to form the coloured markings of a band on its white tube wall outer peripheral surface.
The width of described markings is 0.5-1.5mm.
The manufacture method that has the white polytetrafluoroethylpipe pipe of colored sign line provided by the invention comprises the following step that carries out in order:
1) teflon is divided bulk cargo and as the gasoline of extrusion aid with 100: the weight ratio of 1-50 is mixed into white mixed ingredients, at room temperature places 5-48 hour then to carry out slaking;
2) teflon is divided bulk cargo, as the gasoline of extrusion aid and pigment with 100: the weight ratio of 1-50: 0.1-10 is mixed into colored mixed ingredients, at room temperature places 5-48 hour then to carry out slaking;
3) the inner side margin of the external mold in the blank mould is vertically put into a metal bar shaped mould isometric with the external mold internal height, then by external mold, pour above-mentioned white mixed ingredients in the space that core and mouthful mould constitute through overcuring, reach the height of metal bar shaped mould up to the piling height of white mixed ingredients, take out metal bar shaped mould afterwards, again above-mentioned colored mixed ingredients through overcuring is poured into and taken out in the space of being reserved behind the metal bar shaped mould, install top die at last, and under the pressure of 1-10MPa, pushed depanning and the tubulose hair made is bad 5-15 minute;
4) with the bad top, space that constitutes by external mold, centrum mould, mouthful mould and core on the extrusion die of putting into of tubulose hair, install top die then, afterwards at the pressure of 1-50MPa, the pushing speed of 1-20mm/min, and under the condition of the cooling section of the dryer section of the room temperature of associating-260 ℃, 260 ℃-380 ℃ sintering stage and 380 ℃-200 ℃, push and sintering 10-30 minute the tubulose hair is bad continuously, promptly can be made into the described white polytetrafluoroethylpipe pipe that has colored sign line behind depanning and the natural cooling.
White polytetrafluoroethylpipe pipe and the manufacture method thereof that has colored sign line provided by the invention can utilize the markings of different colours that white polytetrafluoroethylpipe pipe is distinguished fully, when carrying different flowing mediums when concentrating many white polytetrafluoroethylpipe pipes of use like this, operator not only can observe directly the situation of change of every tubing inside from the outside, and it is, therefore convenient, practical according to all right active zone separate different types flowing medium of colored sign line.In addition, this manufacture method can also be used to make the tubing that tube wall and markings have different colours.
