Abstract

PURPOSE:To enable the connection of the members made of PEEK to the firmly achieved by adhering or melding, and more over to improve the surface properties of melded parts by heating and nonfoam-treating at least adjacency to the part to be connected of the member made of polyester etherketone (PEEK). CONSTITUTION:In the connection of the pipe line made of PEEK, first the pipe line parts to be connected, e.g. pipes, joints, valves, etc. are prepared, and the pipe, etc. are cut into required lengths. All these pipe line parts or the adjacency of said parts to be connected, are heated with a heater 1, and while the heated temperature is kept for a constant time, nonfoam-treatment is carried out. Then, the degree or time of heating is different with the shape or size of the parts to be connected, but 200-240 deg.C and 1-3hr are generally determined to be used as a standard. Then, the heater 1 of a cap shape is fitted onto the end of the pipe 2 to be connected, and a suitable heat insulating material 3 is attached to the outer periphery of the pipe 2. Such heating is profitable. The end surface of the pipe is finished smoothly so that no gaps are generated between both end surfaces to be connected of the parts to be connected.

It is abbreviated as KJ. ) Particularly, P
This invention relates to a method for joining PEEK members that is effective for joining piping parts such as EEK pipes, fittings, and valves.

［従来の技術］ 従来の配管等の接合技術には、次のようなものがある。[Conventional technology] Conventional techniques for joining pipes, etc. include the following.

■　接着：　有機溶剤（接着剤）にて被接合材の母材を
溶かして、これを押しつけて一体化する。■ Adhesion: Melt the base material of the materials to be joined using an organic solvent (adhesive) and press them together to integrate them.

［発明が解決しようとする問題点］ 上記■〜■の接合方法は、次のような理由から、ＰＥＥ
Ｋ製の部材には適用することができない。[Problems to be Solved by the Invention] The bonding methods described in ■ to ■ above do not require PEE for the following reasons.
It cannot be applied to K-made members.

■の接着方法は、ＰＥＥＫに適当な、即ちＰＥＥＫを溶
かすことができる有機溶剤（接着剤）がないため、適用
することができない。The bonding method (2) cannot be applied because there is no organic solvent (adhesive) suitable for PEEK, that is, an organic solvent (adhesive) that can dissolve PEEK.

■、■の方法によれば、熱でＰＥＥＫを溶かして接合す

となる。接合部に気泡が残存すると、接合強度は著しく
弱いものとなる上に、接合部に無数の凹凸ができ、実用
には供し得ない接合部材とな、る。According to methods ① and ③, it is possible to melt PEEK with heat and join it, but in this case, air bubbles are generated in the melted part, and these air bubbles remain in the joined part even after joining. . If air bubbles remain in the bonded portion, the bonding strength will be significantly weakened, and the bonded portion will have numerous irregularities, resulting in a bonded member that cannot be put to practical use.

このようなことから、従来より、ＰＥＥＫ製部材に好適
な接合技術の出現が切望されていた。For these reasons, there has been a long-awaited desire for a bonding technique suitable for PEEK members.

It is characterized by fusion bonding.

。In the present invention, prior to heat-melting joining of PEEK members, at least the vicinity of the part to be joined is heated to make it non-foaming, so the generation of bubbles during heat-melting joining is prevented, and air bubbles remain in the joined part. Various problems caused by this can be solved.

［実施例］ 以下、図面を参照して本発明の実施例方法について説明

一例として、ＰＥＥＫ製配管を接合する場合を示す図で
ある。FIGS. 1 to 4 are diagrams showing a case where PEEK piping is joined as an example of the method of joining PEEK members of the present invention.

泡化処理する。In order to join PEEK piping according to the method of the present invention, first, piping parts to be joined, such as a vibrator, a joint, a valve, etc., are prepared, and the vibrator etc. are cut to a required length. Then, the entire piping parts or the vicinity of the parts to be joined are heated with a heater, and this temperature is maintained for a certain period of time to perform a non-foaming treatment.

この場合、加温の程度、時間等は被接合部の形状や大ぎ

℃で１〜３時間程度を目安として適宜決定される。処理
温度が比較的低い場合には、保持時間を長めに設定し、
逆に処理温度が比較的高い場合には、保持時間は若干短
かめでも十分に目的を達し得る。この処理は、接合する
部品の状態、例えば保管期間即ち古さや保管状況等によ
っても異なるため、適宜温度や時間を調節するのが好ま
しい。In this case, the degree of heating, time, etc. vary depending on the shape and size of the parts to be joined, but in normal cases, the temperature is 200~240.
It is determined as appropriate with a standard of about 1 to 3 hours at °C. If the processing temperature is relatively low, set a longer holding time.
On the other hand, if the processing temperature is relatively high, the purpose can be sufficiently achieved even if the holding time is slightly shorter. Since this process varies depending on the condition of the parts to be joined, for example, storage period, ie, age, storage conditions, etc., it is preferable to adjust the temperature and time as appropriate.

It is advantageous to fit a cap-shaped heater 1 into the end of the vibrator 2 to be joined, and attach a suitable heat insulating material 3 to the outer periphery of the vibrator 2 for heating. In the method shown in FIG.
is configured so that it also comes into contact with the end surface of the vibrator 2,
The heating efficiency is good because it can heat the inner peripheral surface of the vibrator, keep the outer peripheral surface warm, and also heat the end surface. Of course, the heating may be performed by heating from the inner circumferential surface of the vibrator, heating from the outer circumferential surface of the vibrator, or heating from the end surface of the vibrator.

That is, if a gap occurs between the end faces to be joined, sufficient welding will not be possible, so the end faces to be joined are subjected to processing such as cutting or polishing to form them so that they can come into contact without a gap.

Although the above molding process can be performed before the non-foaming process, it is better to perform the molding process after the non-foaming process.
It is possible to improve the abutment of the end surfaces to be joined.

In the method shown in FIG. 3, the temperature of the heater 5, the temperature of the heater 5 and the vibrator 2 are
Alternatively, the degree of melting can be adjusted by appropriately selecting the distance to the joint 4, heating time, etc.

By further pressing, for example, by several mm, the materials of the vibrator 2 and the joint 4 are melted and integrated. As a result, as shown in FIG. 4(C), the fused joint A is joined in a manner that it bulges, but if chamfering is applied as described above, this bulge will be extremely small.
