玻璃钢船体清洗剂这种用于清洗玻璃钢船体的清洗剂是由水和NaOCl配制而成的,有效氯的含量为1％～6％。该清洗剂中最好还含有NaOH,OCl~-与OH~-之比为(3～8.4):(1～3)。用途/优点这种清洗剂安全、价廉,能高效地洗除粘附在船体上的绿藻。示例所配制的清洗剂中含有51％(重量比)市售的NaOCl水溶液、1％(重量比)NaOH、48％(重量比)水,它在25℃时的pH值为8.5～9.5,粘度为1.25厘泊。将该清洗剂喷到船体上。静置3～4分钟后,将表面刮净,并用水冲洗,效果良好。
FRP hull cleaning agent This cleaning agent used to clean the FRP hull is formulated from water and NaOCl, the effective chlorine content of 1% to 6%. The cleaning agent preferably also contains NaOH, OCl ~ - and OH ~ - ratio (3 ~ 8.4) :( 1 ~ 3). Uses / Benefits This cleaner is safe, inexpensive and efficient for removing green algae adhering to the hull. The cleaning solution formulated as an example contains 51% by weight aqueous NaOCl solution, 1% by weight NaOH, 48% by weight water, having a pH of 8.5 to 9.5 at 25C, a viscosity 1.25 cps. Spray the cleaning agent on the hull. After standing 3 to 4 minutes, the surface scraping net, and rinse with water, the effect is good.
