Description
本発明は、スクレーパに関する。 The present invention relates to a scraper.
薄い帯状体として例えばフィルムは、ベース材にコーティングや蒸着などの表面処理や、ラミネート等の二次加工、または原料自体の高機能化やハイブリッド化などにより、何らかの機能を付与されることが行なわれている。このような機能性を有するフィルムは、エレクトロニクス、エネルギー、自動車、包装、メディカルなど、非常に多岐な分野で応用されている。 As a thin strip, for example, a film is given a certain function by surface treatment such as coating or vapor deposition on the base material, secondary processing such as laminating, or high functionalization or hybridization of the raw material itself. ing. Films having such functionality are applied in a wide variety of fields such as electronics, energy, automobiles, packaging, and medical.
そして、このようなフィルムの作製工程においては、溶媒への浸漬や、溶媒の洗浄等が行なわれ、品質向上および効率化の観点から、浸漬工程や洗浄工程後に溶媒の除去が行なわれている。 And in the production process of such a film, the immersion in a solvent, the washing | cleaning of a solvent, etc. are performed, and the removal of the solvent is performed after an immersion process and a washing | cleaning process from a viewpoint of quality improvement and efficiency improvement.
浸漬工程や洗浄工程後に溶媒の除去において、スクレーパが用いられている。今般においては、磨耗量が小さく、交換による生産効率を低下させないこと、溶媒の除去効率が高いこと、すなわち、長期間にわたって溶媒の除去効率の高いスクレーパが求められている。 A scraper is used in removing the solvent after the dipping process or the cleaning process. In recent years, there has been a demand for a scraper that has a small amount of wear, does not reduce production efficiency due to replacement, and has high solvent removal efficiency, that is, high solvent removal efficiency over a long period of time.
本開示のスクレーパは、セラミックスからなり、薄い帯状体との接触部を備え、前記帯状体よりも大きい幅を有し、前記接触部は、前記帯状体の進行方向における断面が曲面形状であり、表面に前記幅に沿った複数の稜線を備えていることを特徴とするものである。 The scraper of the present disclosure is made of ceramics, includes a contact portion with a thin strip-like body, has a larger width than the strip-like body, and the contact portion has a curved shape in cross section in the traveling direction of the strip-like body, The surface is provided with a plurality of ridgelines along the width.
本開示のスクレーパによれば、長期間にわたって溶媒の除去効率が高い。 According to the scraper of the present disclosure, the solvent removal efficiency is high over a long period of time.
以下、本実施形態のスクレーパの一例について説明する。 Hereinafter, an example of the scraper of this embodiment will be described.
図１は、本実施形態のスクレーパの一例を示す、（ａ）は斜視図であり、（ｂ）は断面図であり、（ｃ）は（ｂ）におけるＳの拡大図である。本実施形態のスクレーパ１は、セラミックスからなり、薄い帯状体（不図示）よりも大きい幅の接触部２を備える。本実施形態のスクレーパ１は、帯状体を接触部２に接触させることにより、溶媒への浸漬工程や溶媒による洗浄工程後において、溶媒の除去に用いられる部材である。 FIG. 1 shows an example of the scraper of the present embodiment, in which (a) is a perspective view, (b) is a sectional view, and (c) is an enlarged view of S in (b). The scraper 1 of the present embodiment is made of ceramics and includes a contact portion 2 having a width larger than that of a thin strip (not shown). The scraper 1 of the present embodiment is a member used for removing the solvent after the strip-shaped body is brought into contact with the contact portion 2 and after the step of immersing in the solvent or the step of washing with the solvent.
そして、本実施形態のスクレーパ１における接触部２は、帯状体の進行方向における断
面が曲面形状であり、表面に前記幅に沿った複数の稜線３を備えている。本実施形態のスクレーパ１は、セラミックスからなるものであることから、帯状体の接触による摩耗が少なく、交換による生産効率を低下させることが少ない。また、表面に前記幅に沿った複数の稜線３を備えていることにより、溶媒の除去効率に優れる。それゆえ、本実施形態のスクレーパ１は、長期間にわたって溶媒の除去効率が高い。
The contact portion 2 in the scraper 1 of the present embodiment has a curved cross section in the traveling direction of the belt-like body, and includes a plurality of ridge lines 3 along the width on the surface. Since the scraper 1 of this embodiment is made of ceramics, there is little wear due to contact of the belt-like body, and production efficiency due to replacement is hardly reduced. Moreover, it is excellent in the removal efficiency of a solvent by providing the several ridgeline 3 along the said width | variety on the surface. Therefore, the scraper 1 of this embodiment has a high solvent removal efficiency over a long period of time.
スクレーパ１における接触部２の長さ（帯状体の幅方向）としては、帯状体の幅に応じるものであるが、例えば、５０ｃｍ以上数メートルに及ぶものである。 The length of the contact portion 2 in the scraper 1 (in the width direction of the belt-like body) depends on the width of the belt-like body, and is, for example, 50 cm to several meters.
また、本実施形態において、図１（ｃ）に示すように、稜線３間にあたる凹部４の断面形状が曲面形状であるときには、接触部２の接触によって帯状体表面から除去された溶媒中の汚れが付着し詰まりにくいため付着物除去などのメンテナンス作業が不要で溶媒の除去効率も高い。 Further, in this embodiment, as shown in FIG. 1C, when the cross-sectional shape of the concave portion 4 between the ridge lines 3 is a curved shape, dirt in the solvent removed from the surface of the belt-like body by the contact of the contact portion 2 Since it adheres and is not easily clogged, maintenance work such as removal of deposits is unnecessary, and the solvent removal efficiency is high.
また、稜線３の間隔が１０μｍ以上５００μｍ以下であるときには、除去された溶媒を凹部４に保持し易く、汚れの詰まりも起こりにくいのでより溶媒の除去効率を高めることができる。 Further, when the interval between the ridge lines 3 is 10 μm or more and 500 μm or less, the removed solvent can be easily held in the recess 4 and clogging of dirt is less likely to occur, so that the solvent removal efficiency can be further increased.
さらに、凹部４が、前記幅方向において傾斜しているときには、凹部４に保持された溶媒を端面から排出しやすいのでさらに溶媒の除去効率を高めることができる。 Furthermore, when the concave portion 4 is inclined in the width direction, the solvent held in the concave portion 4 can be easily discharged from the end face, and therefore the solvent removal efficiency can be further increased.
次に、セラミックスからなる本実施形態のスクレーパ１としては、アルミナ質焼結体、ジルコニア質焼結体、窒化珪素質焼結体、窒化アルミニウム質焼結体、炭化珪素質焼結体、炭化硼素質焼結体、コージェライト質焼結体、ムライト質焼結体またはこれらの複合物等が挙げられる。材質の選定にあたっては、特性やコスト等の要求に応じて選定すればよいが、コストが低いながらも優れた機械的特性を有しているという点では、アルミナ質焼結体であることが好適である。 Next, the scraper 1 of the present embodiment made of ceramic includes alumina sintered body, zirconia sintered body, silicon nitride sintered body, aluminum nitride sintered body, silicon carbide sintered body, boron carbide Examples thereof include an elementary sintered body, a cordierite sintered body, a mullite sintered body, or a composite thereof. In selecting the material, it may be selected according to requirements such as characteristics and cost, but in view of having excellent mechanical properties at a low cost, an alumina sintered body is preferable. It is.
次に、本実施形態のスクレーパの製造方法について説明する。 Next, the manufacturing method of the scraper of this embodiment is demonstrated.
まず、平均粒径が０．５〜２．０μｍのアルミナ粉末を準備する。また、焼結助剤として、例えば、酸化珪素粉末、炭酸カルシウム粉末、水酸化マグネシウム粉末を用いる。 First, an alumina powder having an average particle size of 0.5 to 2.0 μm is prepared. Moreover, as a sintering aid, for example, silicon oxide powder, calcium carbonate powder, and magnesium hydroxide powder are used.
そして、それぞれの粉末を所定量秤量し、これらの粉末の合計１００質量部に対し、１〜１．５質量部のＰＶＡ（ポリビニールアルコール）などのバインダと、１００質量部の溶媒とを攪拌機内に入れて混合・攪拌してスラリーを得る。 Then, a predetermined amount of each powder is weighed, and 1 to 1.5 parts by mass of a binder such as PVA (polyvinyl alcohol) and 100 parts by mass of a solvent are mixed in the stirrer with respect to a total of 100 parts by mass of these powders. The mixture is stirred and mixed to obtain a slurry.
その後、噴霧造粒装置（スプレードライヤー）を用いてスラリーを噴霧造粒して顆粒を得た後、粉末プレス成形法や静水圧プレス成形法（ラバープレス法）により所定形状の成形体を成形する。また、成形後に切削加工を施すことにより、成形体を得てもよい。なお、成形体形状としては、所定の長さの板状体とすれば良い。 Thereafter, the slurry is sprayed and granulated using a spray granulator (spray dryer) to obtain granules, and then a molded body having a predetermined shape is formed by a powder press molding method or an isostatic press molding method (rubber press method). . Moreover, you may obtain a molded object by giving a cutting process after shaping | molding. In addition, what is necessary is just to set it as the plate-shaped object of predetermined length as a molded object shape.
次に、大気（酸化）雰囲気の焼成炉を用いて、１５００〜１７００℃の最高温度で所定時間保持して焼成し焼結体を得る。そして得られた焼結体に研削加工を施して所定間隔の凹部を有する接触部を形成することにより本実施形態のスクレーパを得ることができる。 Next, using a firing furnace in the atmosphere (oxidation) atmosphere, the sintered body is obtained by firing at a maximum temperature of 1500 to 1700 ° C. for a predetermined time. The scraper of the present embodiment can be obtained by grinding the obtained sintered body to form contact portions having concave portions with a predetermined interval.
なお、本実施形態のスクレーパは金属部材などと係合することが可能であり、回転可能な金属部材に係合すれば、接触位置を変えることができる。また、回転可能な金属部材に複数のスクレーパを係合すれば、一部のスクレーパで溶媒を除去しながら、使用済みのスクレーパを取り換えることもできる。このように、上述した実施形態に限定されるもので
はなく、本発明の要旨を逸脱しない範囲において種々の変更、改良、組合せ等が可能である。
In addition, the scraper of this embodiment can be engaged with a metal member or the like, and the contact position can be changed by engaging with a rotatable metal member. Further, when a plurality of scrapers are engaged with the rotatable metal member, the used scrapers can be replaced while removing the solvent with some scrapers. Thus, the present invention is not limited to the above-described embodiment, and various changes, improvements, combinations, and the like can be made without departing from the scope of the present invention.
