次に、本実施形態の作用効果について説明する。
本実施形態では、ポリ4−メチル−1−ペンテン、または、4−メチル−1−ペンテンと他のαーオレフィンを含む槽壁11と、ポリ4−メチル−1−ペンテン、または、4−メチル−1−ペンテンと他のαーオレフィンを含む槽壁12とを、酸変性ポリ4−メチル−1−ペンテン、または、4−メチル−1−ペンテンと他のαーオレフィンとの共重合体を酸変性した樹脂を含む接合部材13で接合している。
また、ポリ4−メチル−1−ペンテン、または、4−メチル−1−ペンテンと他のαーオレフィンを含む槽壁11とポリ4−メチル−1−ペンテン、または、4−メチル−1−ペンテンと他のαーオレフィンを含む底面部14との接合、ポリ4−メチル−1−ペンテン、または、4−メチル−1−ペンテンと他のαーオレフィンを含む槽壁12とポリ4−メチル−1−ペンテン、または、4−メチル−1−ペンテンと他のαーオレフィンを含む底面部14との接合も接合部材13を介して行っている。
そのため、接合部材13と槽壁11との密着性、接合部材13と槽壁12との密着性、接合部材13と底面部14との密着性が良好であり、処理槽1の液体漏れを抑制することができ、気密信頼性の高いものとすることができる。
ここで、接合部材13と槽壁11との密着性、接合部材13と槽壁12との密着性、接合部材13と底面部14との密着性が良好となる理由は明らかではないが、以下のようなことが推測される。
酸変性ポリ4−メチル−1−ペンテン、または、4−メチル−1−ペンテンと他のαーオレフィンとの共重合体を酸変性した樹脂は、変性前のものに比べ、柔らかくなり、槽壁11、12、底面部14を構成するポリ4−メチル−1−ペンテン、または、4−メチル−1−ペンテンと他のαーオレフィンとの共重合体よりも、融点が低下すると考えられる。そのため、溶融時の易動性が向上し、熱溶融時に被接合物表面に対して拡散しやすくなり、接合が強固なものとなると思われる。
また、酸変性ポリ4−メチル−1−ペンテン、または、4−メチル−1−ペンテンと他のαーオレフィンとの共重合体を酸変性した樹脂は、変性前のものに比べ、柔らかくなるため、接合後において外力を吸収しやすくなり、接合部材13と、被接合物とが分離しにくくなっているとも考えられる。
Next, the effect of this embodiment is demonstrated.
In the present embodiment, the tank wall 11 containing poly-4-methyl-1-pentene or 4-methyl-1-pentene and another α-olefin, and poly-4-methyl-1-pentene or 4-methyl- The tank wall 12 containing 1-pentene and another α-olefin was acid-modified from acid-modified poly-4-methyl-1-pentene or a copolymer of 4-methyl-1-pentene and another α-olefin. It joins with the joining member 13 containing resin.
Further, the tank wall 11 containing poly-4-methyl-1-pentene or 4-methyl-1-pentene and other α-olefin and poly-4-methyl-1-pentene or 4-methyl-1-pentene Bonding with bottom part 14 containing other α-olefin, poly 4-methyl-1-pentene, or tank wall 12 containing 4-methyl-1-pentene and other α-olefin and poly-4-methyl-1-pentene Alternatively, the bonding between the 4-methyl-1-pentene and the bottom surface portion 14 containing other α-olefin is also performed through the bonding member 13.
Therefore, the adhesiveness between the joining member 13 and the tank wall 11, the adhesiveness between the joining member 13 and the tank wall 12, and the adhesiveness between the joining member 13 and the bottom surface part 14 are good, and the liquid leakage of the processing tank 1 is suppressed. And airtight reliability can be high.
Here, the reason why the adhesiveness between the joining member 13 and the tank wall 11, the adhesiveness between the joining member 13 and the tank wall 12, and the adhesiveness between the joining member 13 and the bottom surface part 14 is not clear is not clear, but I guess that.
Resin obtained by acid-modifying acid-modified poly-4-methyl-1-pentene or a copolymer of 4-methyl-1-pentene and another α-olefin becomes softer than that before modification, and the tank wall 11 12, the melting point is considered to be lower than that of poly-4-methyl-1-pentene constituting the bottom surface portion 14 or a copolymer of 4-methyl-1-pentene and other α-olefin. For this reason, the mobility at the time of melting is improved, it becomes easy to diffuse to the surface of the object to be bonded at the time of heat melting, and it seems that the bonding becomes strong.
Moreover, acid-modified poly-4-methyl-1-pentene or a resin obtained by acid-modifying a copolymer of 4-methyl-1-pentene and another α-olefin becomes softer than that before modification. It can be considered that external force is easily absorbed after joining, and the joining member 13 and the article to be joined are difficult to separate.

また、本実施形態では、槽壁11,12、底面部14がポリ4−メチル−1−ペンテン、または、4−メチル−1−ペンテンと他のαーオレフィンを含み、接合部材13が酸変性ポリ4−メチル−1−ペンテン、または、4−メチル−1−ペンテンと他のαーオレフィンとの共重合体を酸変性した樹脂を含むことから、各部材間の線膨張係数差を小さくすることができる。これにより、処理槽1内の液体の温度を高い温度とした場合であっても、処理槽1に熱歪が生じることを抑制でき、処理槽1の液体漏れを確実に抑制することができる。   Moreover, in this embodiment, the tank walls 11 and 12 and the bottom face part 14 contain poly 4-methyl-1-pentene, or 4-methyl-1-pentene and another α-olefin, and the joining member 13 is acid-modified poly. Since 4-methyl-1-pentene or a resin obtained by acid-modifying a copolymer of 4-methyl-1-pentene and another α-olefin is included, the difference in linear expansion coefficient between the members can be reduced. it can. Thereby, even if it is a case where the temperature of the liquid in the processing tank 1 is made into high temperature, it can suppress that a thermal distortion arises in the processing tank 1, and the liquid leak of the processing tank 1 can be suppressed reliably.

さらに、本実施形態の処理槽1は、ポリ4−メチル−1−ペンテン、または、4−メチル−1−ペンテンと他のαーオレフィンとの共重合体を含む槽壁11と、ポリ4−メチル−1−ペンテン、または、4−メチル−1−ペンテンと他のαーオレフィンとの共重合体を含む槽壁12と、ポリ4−メチル−1−ペンテン、または、4−メチル−1−ペンテンと他のαーオレフィンとの共重合体を含む底面部14と、酸変性ポリ4−メチル−1−ペンテン、または、4−メチル−1−ペンテンと他のαーオレフィンとの共重合体を酸変性した樹脂を含む接合部材13とで構成されているため、耐熱性が高く、耐薬品性にも優れ、かつ、槽壁のポリ4−メチル−1−ペンテン、4−メチル−1−ペンテンと他のαーオレフィンとの共重合体は光学的に透明であるため外部からの視認性に優れたものとなる。したがって、処理槽1は、エッチング槽等に適したものとなる。   Furthermore, the processing tank 1 of this embodiment includes a tank wall 11 containing poly-4-methyl-1-pentene or a copolymer of 4-methyl-1-pentene and another α-olefin, and poly-4-methyl. A tank wall 12 containing a copolymer of -1-pentene or 4-methyl-1-pentene and another α-olefin, and poly-4-methyl-1-pentene or 4-methyl-1-pentene The bottom part 14 containing a copolymer with another α-olefin and the acid-modified poly-4-methyl-1-pentene, or the copolymer of 4-methyl-1-pentene and another α-olefin were acid-modified. Since it is comprised with the joining member 13 containing resin, heat resistance is high, it is excellent also in chemical resistance, and poly 4-methyl-1- pentene of a tank wall, 4-methyl-1- pentene, and other Copolymers with α-olefins are optically transparent. Since it is bright, it is excellent in visibility from the outside. Therefore, the processing tank 1 is suitable for an etching tank or the like.

また、槽壁12の表面と、槽壁11の端面とを接合させず、たとえば、槽壁12の端面と、槽壁11の端面とを、接合部材として酸変性ポリ4−メチル−1−ペンテン(または、4−メチル−1−ペンテンと他のαーオレフィンとの共重合体を酸変性した樹脂)の粉末を介して接合して、一枚の槽壁を作製してもよい。
