Product information
Unitor™ Descaling Liquid™ is an acid based liquid product that contains corrosion inhibitors and that is highly effective to remove scale and rust. It should not be used on aluminium, zinc, tin, stainless steel, titanium or any other galvanized surfaces for which a special grade cleaner is recommended by the manufacturer.
Unitor™ has developed Cargo Hold Cleaning Kits and appropriately tested for use with Descaling liquid solution for efficient removal of cargo sediments such as cements, lime wash and similar products from hold bulkheads.
Unitor™ Panamax Cargo Hold Cleaning Kit, PN 778855
Unitor™ Cargo Hold Compact Kit, PN 778955
To avoid unnecessary corrosion of the cleaning kits, it is highly recommended to flush the equipment with fresh water regularly during cleaning, between each cargo hold and before storage.
Furthermore, Unitor™ has also developed a 210 litres capacity cleaning unit designed for use with chemical acid solutions for cleaning boilers, calorifiers, heat exchangers and other types of similar equipment where rust and scale removal is necessary.
Unitor™ Chemical Cleaning Unit: PN 737189.
Notes regarding safety in descaling operations:
Descaling liquid contains strong acids. Handle with care and pay special attention to Material Safety Data Sheet and / or Product Label. Use personal protection equipment as recommended.
Reactants from acid components in descaling products may include gasses like carbon dioxide and hydrogen. Formation of hydrogen gas can be monitored with gas detection equipment on the vents. To avoid suffocation and potentially explosive atmosphere, gasses should be removed safely by purging system with water after draining the cleaning solution. Vent of system during descaling operations must be provided for same reason. Always use gas detection equipment to check that the atmosphere is safe before entering confined spaces for inspection after descaling operations. When circulating the descaling solution, always circulate with inlet at the bottom to avoid air pockets and potential entrapment of gaseous reaction products.

- Approved by the Norwegian National Institute of Public Health for cleaning of evaporators.
Directions for use
The most effective descaling is accomplished by circulation for large systems or components. In the case of small components, the soak method in an immersion bath can be used.
If the equipment to be cleaned is contaminated by oil, grease, sludge or carbonised oil, then pre-cleaning with Unitor™ Seaclean Plus™ or Unitor™ Enviroclean™ is necessary.
Unitor™ Descaling Liquid™ should always be used in plastic containers. Acid should always be added to water, and never the reverse.
Unitor™ Descaling Liquid should be mixed with fresh water to form a solution of 10--30%, depending on the extent of scaling. After using Unitor™ Descaling Liquid it is essential to thoroughly rinse all metal surfaces at least once with a 0.5% solution of Nalfleet™ Alkalinity Control™ in fresh water. This solution should be circulated for 2--4 hours or until an acceptable pH value is obtained. This will neutralize any remaining acidity and passivate steel surfaces.

有关除垢操作安全性的说明：
除垢液含有强酸。小心操作并特别注意材料安全数据表和/或产品卷标。使用推荐的个人防护设备 。
来自除垢产品中的酸组分的反应产物可包括气体如二氧化碳和氢气。可以使用通风口上的气体检测设备监测氢气的形成。为避免窒息和潜在的爆炸性气体 ，在排出清洁溶液后，应通过用水清洗系统来安全地清除气体。出于同样的原因，必须提供除垢操作期间系统的排放 。
必须持续使用气体检测设备
在进行除垢操作后进入密闭空间检查之前检查大气是否安全。循环除垢溶液时 ，始终在底部进口处循环，以避免气穴和气态反应产物的捕获。

认证
• 根据MARPOL附则V，该组合物符合不对海洋环境有害的标准，并且当用于清洁货舱和船舶外表面时可以排入海中。
• 由挪威国家研究所批准公共卫生用于清洁蒸发器。.
使用说明
最有效的除垢方法是将大型的主体或零件 ，加以循环清洗；若是较小的组件，可以浸泡方式为之 。
需要清洗的设备若已被油脂、污物或碳灰等污染，则必须先以Tankclean或Seaclean先行洗净。除垢剂之浓度应视现有结垢之程度以清水调合而成，约在10%~30%之浓度。使用过除垢剂后，必需以含0.5%浓度之Alkalinity control溶液清洗至少一次，此溶液应
循环2~4小时，或至可接受之酸碱质(PH值)，而可中和金属表面残留之酸剂。
Unitor™ Descaling Liquid是一种以盐酸为基之酸性溶液 ，故不可使用于铝 、锡、锌、镀锌及不锈钢等金属表面。
化学清洗标准WILHELMSEN公司有专为除垢用之280公升标准容器 ，以供锅炉、洁净机 、热交换器等除垢循环使用。
