Potassium thiocyanatum phosphationis treatment metalorum non ferros tantum saltum potassium thiocyanatis calvanising phosphate sodium dihydrogenum galvanising tantum est, et alios ingredientus, sicut sulfate aluminium, pipa quadrata Q345B ferentis ferentis causa scientiae, alkali edibile etc., solutione platingae solventur. The galvanized square steel pipe is added with sodium hydroxide solution to convert it into insoluble nickel hydroxide and remove it by precipitation. Organik chemical preservatives için, pulveri activated carbon absorbe ve kaldır.Sulfate Aluminium et sulfate aluminium potassium uno tempore perfecto removi non potest.Q345B square tube-Q345B seamless square tube-Q345B square steel tube-Q345B cold drawn square tube-Shandong Dingyu Metal Material Co., Ltd. has good gloss for Q345B seamless square tube coating The impact is not serious.According to the solution, the knowledge of the cause of wrinkling of Q345B square steel pipes can be supplemented according to the components required by new technologies and new processes.Galvanised pipes quadraticos fertilibus sunt particular fluctus production is causa nulla sexura quae post passivationem trationem non mundata est.
, The galvanized square steel pipe depends on the production line trough and the trough are broken holes directly, and the aqueous solution doesn't get out or overflow.Each process flow in the processing process is composed of a breathing system.Each tank aqueous solution is strong acid and strong alkali solution, electroplating process solution, luminescence and passivation agent, etc., only the recycling system does not leak or drain outside the system software, and there are only a few production lines.To clean the tank, select the recycling system to re-use the sewage on time, especially the production process flow caused by no sewage that is not cleaned after the passivation treatment.
