Directions for use

Dosing method
Unitor™ Metal Brite H.D. should always be used in a plastic bucket.
Acid should always be added to water, never the reverse.
Remove dirt, rust flakes, oil and grease prior to using Unitor™ Metal Brite H.D.

Apply Unitor™ Metal Brite H.D. to surfaces to be cleaned or pickled as follows:

For severely corroded surfaces and pickling of welding repairs, use 50% solution to neat.

For less severely corroded or soiled surfaces and tarnish on copper and brass, use a solution of 20--50%, and rinse off surface after 15--40 minutes with water.

On aluminium, use a solution of 10--30%, but rinse off surface maximum 5 minutes after application.

For removal of rust stains on painted surfaces, a solution of 10--30% should be sufficient. Rinse off with water 15--20 minutes after application.

For removal of rust stains on ceramic tiles, enamels, porcelain, glass etc., use a solution of 20--50%, depending on stains and soiling. Rinse off with water after 20--40 minutes.

For removal of light cement stains and lime, apply a 50% solution, and high pressure wash after 30--40 minutes, and for solidified cement use Unitor™ Descaling Liquid.

For removal of light rust and scale in pipelines and tanks, recirculate a solution of 5--10% Unitor™ Metal Brite H.D. For discoloration of stainless steel and epoxy coated tanks use the same method.

For removal of white residues from epoxy-coatings that sometimes remains after carriage of Stearin, Olein, Palm fatty acid etc., recirculate a solution of 5--10% Unitor™ Metal Brite H.D. When injected, use a 5% solution. Recirculate or inject until residue is removed.

使用说明

Unitor™ METAL BRITE HD应使用塑料桶，应将溶剂加入水中；切不可将水加入溶剂中。

在使用METAL BRITE HD前，应将松散之脏物、铁锈及油脂先行清除。使用METAL BRITE HD于欲清洁处理表面之方式：较严重的腐蚀表面及电焊后的处理，应使用50%浓度的溶液。对于黄铜及青铜表面之较轻微腐蚀、弄脏或不光洁，可用20-25%浓度的溶液，约15-40分钟后再用清水冲洗。

至于铝金属，可使用10-30%之溶液，5分钟后再用水冲洗金属表面。清除油漆表面之锈渍，可使用10-30%浓度之溶液，15-20分钟后再用清水冲洗。清洗陶瓷、珐琅、瓷釉及玻璃等之锈渍，依其锈蚀及肮脏程度使用20~50%浓度之溶液，约20~40分钟后再以清水冲洗之。

清洗水泥及石灰，使用50%浓度之溶液，约30~40分钟再以高压水冲洗之。若要清除货舱及其管路、不锈钢货舱、环氧漆货舱之锈渍，可用5-10%浓度之溶液，佐以循环方式。若添加新溶液亦用5%浓度，不断循环及添加，直至锈渍或锈色去除为止。
