本発明は硝子容器等を成形する際に使用する金型シシー
ート聾等に強固に付着した硬質カーボンの効果的な除去
法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an effective method for removing hard carbon firmly adhered to mold sheet metal plates used in molding glass containers and the like.
硝子容器等を成形するには金型が必要であり、その使用
に際しては、成形品を金型から容易に脱離させる目的で
、油とグラファイト等を主成分とした離型剤を塗布する
。 離型剤は溶融された硝子と常に接触するため１次第
に硬質カーボンと化し。A mold is required to mold glass containers, etc., and when using the mold, a mold release agent mainly composed of oil and graphite is applied in order to easily release the molded product from the mold. Since the mold release agent is constantly in contact with the molten glass, it gradually turns into hard carbon.
金型に強固に付着し、離型効果を減退すると共に不良品
発生の原因となる。It adheres firmly to the mold, reducing the mold release effect and causing defective products.
法を繰返し適用していると、金型を損耗し、その精度を
低下すするため再使用することが出来なくなる場合が多
く、金型を損耗させないで付着物を除去する方法が要望
されているのが現状である。Repeated application of the method wears out the mold and reduces its accuracy, making it impossible to reuse it.Therefore, there is a need for a method to remove deposits without damaging the mold. is the current situation.
本発朗者は金型等の付着物を効果的に除去すると共に金
型を損耗しない除去法を見い出すべく種々検討、試験を
した結果。The inventor conducted various studies and tests to find a method for effectively removing deposits from molds, etc., without damaging the molds.
アルカリ性水溶液と酸性水溶液を併用する方法が効果的
であることを見出し９本発明をするに至ったものである
。It was discovered that a method of using an alkaline aqueous solution and an acidic aqueous solution in combination is effective, and this led to the present invention.
金属に付着した油等を除去する目的で、アルカリ注水＠
液又はアルカリ性物質と界面活性剤とよりなる水溶液に
よる除去法才酸化物の溶解除去には効果的であるが硬質
カーボンの除去には不適当である。Alkaline water injection @ for the purpose of removing oil etc. adhering to metal
A removal method using a liquid or an aqueous solution consisting of an alkaline substance and a surfactant is effective for dissolving and removing oxides, but is unsuitable for removing hard carbon.
本発明は汚染した金型を先づアルカリ性物質、界面活性
剤。In the present invention, the contaminated mold is first treated with an alkaline substance and a surfactant.
及びグルコン酸ソーダとよりなる水溶液に一定時間浸清
し９次いで酸腐蝕抑制剤を含有した酸性水溶液に、短時
間浸漬後、水洗いすることにより、金型を損耗させるこ
となく、付着した硬質カーボンを、完全に除去し得るも
のである。By immersing the mold in an aqueous solution containing sodium gluconate and sodium gluconate for a certain period of time, and then immersing it in an acidic aqueous solution containing an acid corrosion inhibitor for a short time and washing with water, the attached hard carbon can be removed without damaging the mold. , which can be completely removed.
アルカリ性物質、界面活性剤、及びグルコン酸ソーダと
より分間浸漬すれば充分である。 この浸漬径、酸性水
溶液に１〜２分間浸清し、その後に水洗いすることによ
り除去目的が達せられる。Soaking with an alkaline substance, surfactant, and sodium gluconate for a longer period of time is sufficient. The purpose of removal can be achieved by immersing in an acidic aqueous solution for 1 to 2 minutes and then rinsing with water.
沢が得られる。A stream can be obtained.
即ちグルコン酸ソーダを配合しない場合、金型表面は、
アルカリ洗浄前と同様な状態のままであり、これを後処
理の酸性水溶液への浸漬で、きれいな状態にしようとす
れば、浸漬時間が長くなり金型が酸により浸蝕されるば
かりでなく表面が粗面となり好ましくない。In other words, when sodium gluconate is not blended, the mold surface is
The condition remains the same as before the alkaline cleaning, and if you try to clean it by dipping it in an acidic aqueous solution as a post-treatment, the dipping time will be longer, and not only will the mold be eroded by the acid, but the surface will also be damaged. The surface becomes rough, which is not desirable.
本発明に使用するアルカリ性物質としては水酸化アルカ
リの他珪酸塩、炭酸塩等の単品又は混合品が使用可能で
あるが、価格。As the alkaline substance used in the present invention, alkali hydroxides, silicates, carbonates, etc. can be used singly or as a mixture, but the price is high.
効果等の面から水酸化ナトリウムを使用するのが好まし

格、配合品の安定性等の面から、水酸化ナトリウムは２
０〜３０％、グルコン酸ソーダは３〜５％、界面活性剤
は１〜２％の配合が好ましい。。From the viewpoint of effectiveness, it is preferable to use sodium hydroxide, and its concentration varies depending on the state of contamination, but generally 10
~40%, sodium gluconate from 1 to 10%, surfactant from 0.5 to nonionic or anionic single or mixed products
Although it is possible to use an aqueous solution containing 5% sodium hydroxide, from the viewpoint of price, stability of the compounded product, etc.
Preferably, the content is 0 to 30%, sodium gluconate is 3 to 5%, and surfactant is 1 to 2%. .
酸性水溶液としては塩酸、リン酸等の無機酸の他、クエ
ン酸。Examples of acidic aqueous solutions include inorganic acids such as hydrochloric acid and phosphoric acid, as well as citric acid.
シュウ酸等の有機酸の単品又は混合品が使用出来るが、

剤は、１％前後を配合することにより充分な効果が得ら
れる。Single or mixed organic acids such as oxalic acid can be used, but
Hydrochloric acid is preferably used from the viewpoint of effectiveness and cost, and its concentration is preferably 5 to 15%. If it is less than 5%, it will be less effective in short-term treatment, and if it is more than e1596, it will emit a pungent odor and corrode the mold surface. Excessive licking is undesirable, and a sufficient effect can be obtained by incorporating the acid corrosion inhibitor in an amount of about 1%.
酸腐蝕ｇ制剤を添加しない場合、短時間浸漬するとはい
え。If no acid corrosion inhibitor is added, it will be immersed for a short time.
金型への浸蝕があり、繰返し処理するときには１表面が
粗面となり、金型自体が使用不能となるが、酸腐蝕抑制
剤を加えることにより、このようなことはない。There is corrosion to the mold, and when repeated processing, one surface becomes rough and the mold itself becomes unusable, but this does not occur by adding an acid corrosion inhibitor.
酸腐蝕抑制剤としては、一般に市販されているポリアミ

減出来る。In actual work, considering the economic efficiency of the chemical solution, the alkaline components adhering to the mold are removed by immersion in an aqueous solution containing an alkaline substance, a surfactant, and sodium gluconate. The consumption of the acidic aqueous solution can be reduced by immersing it in an acidic aqueous solution and then rinsing it with water to remove any deposits that are easily removed.
