Metalworking — Process Challenge

加工部品用防食剤

鉄系・非鉄系部品は工程内および仮置き保管中に瞬間錆や変色(くすみ)を生じる。設計には鉄系および銅合金系(イエローメタル用)防食剤が求められる。

ソリューションアプローチ

RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Selection Workflow
1
Process & Requirement Definition
Map the unit operation and define the functional, purity, and regulatory requirements the chemical input must meet.
2
Chemistry & Grade Selection
Match the solvent, intermediate, acid or base, catalyst, or specialty additive to the process and downstream compatibility.
3
Trial & Specification
Validate performance at bench or pilot scale, and set the grade, treat rate, and packaging to match throughput and handling.
4
Quality & Supply Assurance
Lock the spec with a CoA and secure multi-origin sourcing for supply resilience and consistent lot quality.

Benzotriazole (BTA)
CAS 95-14-7
特殊添加剤
Copper and yellow metal corrosion inhibitor
Chemisorbs onto copper and brass to build a Cu-BTA monolayer that blocks oxygen access, stopping tarnish on non-ferrous machined components
融点:98–100 °C   沸点:204 °C at 15 mmHg   密度:1.36 g/cu cm at 20 °C

詳細情報
Tolyltriazole (TTA / Methylbenzotriazole)
CAS 29385-43-1
特殊添加剤
防腐
Methyl (tolyl) triazole gives the same copper-passivating film as BTA with better solubility and persistence in alkaline coolants

2-Mercaptobenzothiazole (MBT)
CAS 149-30-4
特殊添加剤
防食
2811 (2-MERCAPTOBENZOTHIAZOLE) · Class
Thiazole that chemisorbs through its sulfur onto copper and brass to form a protective film; primarily a yellow-metal inhibitor for soluble-oil systems, paired with nitrite/molybdate when steel must also be protected
融点:177–181 °C   沸点:Decomposes   密度:1.42 at 20 °C
