アルカリ洗浄薬剤

Caustic soda for alkaline parts cleaning, plus hydrochloric and phosphoric acid for descaling, pickling, and phosphate surface prep u2014 bulk supply for industrial manufacturing.

概要

アルカリ洗浄薬剤は、油、グリース、工場汚れをけん化・乳化することで金属部品から除去する高pHの配合品です。 工業製造分野では、このファミリーはpHスケール上で正反対の二つの役割を担います:有機汚れを除去する苛性ソーダ系・ケイ酸塩系のアルカリ洗浄剤と、スケール、錆、酸化物を溶解する鉱酸です。多くの部品洗浄ラインは両者を順に運転します — アルカリ洗浄の後に酸によるスケール除去または酸洗 — どちらも他方の汚れは落とせないためです。

Caustic soda (sodium hydroxide) is the workhorse alkali for industrial parts cleaning. It is dosed to build the bath pH that saponifies oils and lifts shop grime. Caustic is aggressive on aluminum and zinc, so specify it for ferrous parts, or pair it with an inhibitor and a silicate buffer when cleaning soft metals. Buying it in beads simplifies dosing and storage versus liquid caustic for shops that mix baths on demand.

Hydrochloric and phosphoric acid handle the descaling side. Hydrochloric acid pickles mill scale and rust fast, but it attacks the base metal if a part soaks too long, so control concentration and dwell time. Phosphoric acid works more slowly, leaves a mild phosphate film that aids paint adhesion, and is preferred where some flash-rust protection between steps is wanted. The trade-off is speed against substrate loss: fast pickling costs metal.

よくあるご質問
アルカリ洗浄と酸によるスケール除去の違いは何ですか?
Alkaline cleaners such as caustic soda and silicates run at high pH and remove oils, greases, and shop soils by saponification and emulsification. Acid descalers such as hydrochloric and phosphoric acid run at low pH and dissolve inorganic scale, rust, and oxide that alkaline cleaning leaves behind. Many parts lines use an alkaline wash followed by an acid step because each removes a different soil.
鋼のスケール除去にはどの酸を使うべきですか — 塩酸かリン酸か?
Hydrochloric acid removes mill scale and rust quickly but will attack the base metal if dwell time is too long, so it suits fast pickling under controlled concentration. Phosphoric acid works more slowly, leaves a thin phosphate film that aids paint adhesion, and is used where flash rust between steps is a concern. Confirm regulatory status for your application and jurisdiction.
RawSourceは苛性ソーダおよびスケール除去用酸をバルクで供給していますか?
はい。RawSourceは工業洗浄および表面処理ライン向けに、苛性ソーダ(水酸化ナトリウム)ビーズ、塩酸、リン酸を、ドラム、トート、バルクの各数量で調達します。濃度、グレード、包装形態の要求を添えてバルクRFQをご送信ください。
Caustic soda はアルミニウム部品の洗浄に使用できますか?
Caustic soda is aggressive toward aluminum and zinc and will etch them. For soft-metal cleaning, an inhibited or silicate-buffered alkaline formulation is used in place of straight caustic. Specify the substrate when selecting an alkaline cleaner.
