墨水的成分對於廠商而言是一項商業機密,所以我們無法得知對筆尖或其他接觸墨水部分金屬的腐蝕性有多強.但這裡有個PH值數據給您做參考
PH值代表著墨水本身的酸鹼強度
1.7 for Omas Blue-Black, Omas Royal Blue, Visconti, Lapis Blue; 2.2 for Montblanc Blue-Black, Montblanc Bordeaux, Pelikan Blue-Black, Visconti Turquoise; 2.6 for Caron d'Ache Imagine in Blue Sky 2.7 for Pelikan 4001 Blue, Visconti Permanent Blue-Black, Pelikan 4001 Turquoise, Quink Washable Blue, Waterman Purple; 2.8 for Caran d'Ache Escape in Caribbean Sea 3.0 for Montblanc Emerald Green, Quink Permanent Black, Waterman Blue-Black, Waterman Blue; 4.0 for Sheaffer Brown, Emerald Green, Peacock Blue; 5.5 for Caran d'Ache Dream in Blue Night 5.6 for Caran d'Ache Protect in Storm 6.1 for Caron d'Ache Travel in Grand Canyon 6.3 for Parker Penman Emerald; 6.5 for Omas Sepia; 6.6 for Parker Penman Ebony; 6.8 for Herbin Green, Omas Vespucci Red, Parker Penman Mocha, Parker Penman Sapphire; 7.0 for Waterman Havana 7.2 for Omas Permanent Black; 7.5 for Parker Penman Ruby; Pelikan Brilliant Green; 7.8 for Visconti Black 7.9 for Rotring black, Waterman red, Caran d'Ache Explain in Carbon 8.2 for Pelikan brilliant red, turquoise, violet - 9.0 for Sheaffer jet black
常見的專業墨水Noodler's ink ˇ的pH值 約 6.2 to 7.9. PH值1-4間的酸性算很強,對一些金屬具有相當的腐蝕性喔 |
