FT-50W Chromium free passivator (no washing)
Ft-50W chromium free and water free passivator is composed of oxidant, surfactant and complexing agent. It doesn't contain heavy metal elements such as nickel, chromium, lead and cadmium. This environmental friendly product is used for chromium free conversion coating treatment of aluminum and aluminum alloy plates and parts; It also can be used as paint pretreatment, mainly as polyester powder coating pretreatment.
■Product type: Chrome-free environmental friendly type
■Practical technology:Impregnating,spraying
■Application: Aluminum and aluminum alloy
■Product Description: Acid water solution, colorless, no special smell
■Product advantages:
(1) The dosage is small and 0.3% medicament is added in slotting
(2) Low consumption per ton, about 0.5 ~ 1.0 kg, low production cost.
(3) Effectively enhance the adhesion and corrosion resistance of coating.
(4) It fully conforms to European and American technical standards and environmental protection standards.
■Technological process:
Aluminum degreaser cleaning → water washing → water washing → pure water washing →ft-50w treatment → drying → spraying
■Product use:
Materials required:FT-50W
Pure water: Deionized water with conductivity less than 20us / cm
■Preparation for trench construction:
Inject 3/4 full pure water into the tank, start the pump circulation, add the measured ft-50w, and mix evenly.
■Channel construction management:
PH value of tank solution: 3.2-4.2
Bath temperature: normal temperature
Conductivity: 50-150us / cm
Aluminum ion: less than 30 mg / L
■Tank liquid maintenance:
In the production process, the pH value and conductivity of the bath solution should be analyzed regularly. Generally, the bath solution can be used stably only by adding chemicals normally. 20kg ft-50w chromium free passivator should be added for every 40 tons of aluminum processed. The chromium free passivation tank needs to be equipped with filtration cycle, and the concentration of aluminum ion will gradually increase with the increase of treatment output. When the amount of aluminum ion increases rapidly, it is recommended to drain a certain amount of tank liquid regularly to maintain the level of aluminum ion. It is recommended to renew the tank liquid once every three months to half a year.
■Use of conversion film treatment:
Application process: impregnating, spraying
Passivation time: impregnating (40 ~ 70s), spraying (40 ~ 70s)
Bath temperature: normal temperature
■Drying process:
It can be dried naturally or conditionally
■Technical services:
The best working condition will be determined by our technical service personnel before the production line starts to run.
■Tank equipment:
The following materials are applicable to all equipment parts and tank body contacting with ft-ld-001 chromium free passivator tank liquid:
Polyvinyl chloride (PVC), polypropylene (PP), polydifluoroethylene (PVDF), polytetrafluoroethylene (PTFE).
■Wastewater treatment:
All waste water must be treated according to the national and local laws and regulations before being discharged into the sewer.
■Safety management:
Please use protective glasses and gloves.
Clean with clean water when attached to skin.
Wash eyes with plenty of water for more than 15 minutes and see a doctor in time.
Drink plenty of water to dilute and see a doctor in time.
■Storage requirements:
store in a cool and ventilated place at 0 ~ 40 ℃.
