22W Alkaline Degreaser
Alkaline degreaser 22W is composed of surfactant and complexing agent. It does not contain heavy metal elements such as nickel, chromium, lead and cadmium. It is an environmental protection product. This product is used for cleaning and degreasing the surface of aluminum and aluminum alloy plates and parts; It can be used as pretreatment of passivation spraying.
Product type: chromium free environmental protection type
Application process: dipping, spraying
Application: aluminum and aluminum alloy
■Product advantages:
(1) Low consumption per ton, about 2 ~ 3 kg, low production cost.
(2) High oil removal efficiency, clean and bright workpiece surface after cleaning.
(3) It fully conforms to European and American technical standards and environmental protection standards.
■Technological process:
22W cleaning → water washing → water washing → pure water washing → passivation → drying → spraying
■Product use:
Materials required:
Degreaser 22W: 3%
Additive 23ad: 0.3%
Tap water or pure water
■Preparation for trench construction:
Inject 3 / 4 full pure water or tap water into the tank, start the pump circulation, add the measured 22W and 23ad, and mix evenly.
■Channel construction management:
Bath temperature: normal temperature
Free alkali: 10 ~ 30
Aluminum ion: less than 6G / L
■Tank liquid maintenance:
In the production process, the aluminum ion and free alkali in the tank liquid should be analyzed regularly. Generally, it can be used stably only by adding chemicals normally. Adding 3 kg 22W per ton of tank liquid can increase the free alkali by 1 point.
During the production, the floating oil and impurities in the oil removal tank should be cleaned in time, and the filter screen should be cleaned in time. When the aluminum ion concentration is close to the upper limit, part of the tank liquid can be discharged, and the same volume of chemicals can be added according to the amount of groove; When the aluminum ion concentration exceeds the upper limit, the tank can be changed again.
■Use of cleaning and degreasing:
Application process: dipping, spraying
Passivation time: dipping (2 ~ 10min), spraying (60 ~ 120s)
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-22w tank liquid:
Stainless steel, PVC, PP, PVDF, 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 ℃.
■Specifications and packaging:
Sealed package, net weight 20kg / 25kg. The specific specifications are subject to the actual delivery.
