Cleaner For GI
- BT
- SHENYANG
Cleaner BT-4338 is an alkaline degreasing agent compounded by various alkalis, surfactants and water treatment agents. can be used as the cleaner for GI(galvanized steel)、 SPCC、carbon steel、、Zinc alloyed steels(GA).
the cleaner can be also used forcleaner pre-silane treatment for GI(galvanized steel)， and so on.
the cleaner can bo also used for cleaner ready for silane treatment for GI(galvanized steel)，and so on.
The cleaner consists of two dosage forms, A and B.
Compared with similar products at home and abroad, cleaner for SPCC has the following advantages:
1、fast degreasing,
2、simple operation
3、convenient management.
4、the most important advantages of fast oil removal,
It has a good cleaning effect on all kinds of organic oil, mineral oil and dirt.
the cleaner can be used by spraying, dipping and other methods.
Degreaser bt-4338 is an alkaline degreaser composed of a variety of substances with a ph greater than seven. With the development of technology. Surfactants appeared, which could be used with alkaline aqueous solutions. It not only preserves the advantages of alkaline degreasing agent cost-effective, but also can greatly improve deoiling efficiency, reduce degreasing temperature, compared with the simple use of surfactants, that is to reduce the cost of buying other materials, and high efficiency degreasing effect. Therefore, it is widely used in the pretreatment process. Alkaline degreaser also has related disadvantages: 1) need rinsing; 2) The plating tank life is short; 3) High energy consumption; 4) Need to neutralize acid; 5) Need to remove residual oil treatment; 6) Follow-up procedures are required. The product needs to use A (1%), B (2%) two dosage forms, and then add water to replenish the liquid level, fully stir.
Product characteristics
1. This agent has strong penetration and emulsifying power, and can fine granulate grease and dirt hidden in the depths, and can make it out of the metal surface.
2, this agent is weak alkaline, can not corrode metal, it is best to use cold water washing.
3, this agent is white powder, stable property, good heat resistance, can be preserved for a long time, so is its aqueous solution.
Usage method
Recommended ratio: 5-10%, operating temperature: normal temperature, operating concentration (alkalinity) : 20-50 points, degreasing time: 10-20 minutes
1, several workpiece surface grease and dirt too much, viscosity is too high and not easy to fall off, can be appropriately increased concentration, the highest concentration shall not exceed 20%.
2, degreasing time depends on the processing workpiece state and working concentration, temperature and other factors, usually according to the above situation.
3. After degreasing, clean it with clean water (overflow state).
Concentration method
Take 10ml of the working solution, use phenolphthalein as an indicator, titrate with 0.1n H2SO4 standard solution, so that the 0.1N H2SO4 ml of solution consumed when the determination solution changes from red to colorless is the free alkalinity of the working solution (point).
Concentration management method
(in 1 ton tank)
a. When using degreaser, the concentration should be kept within the reference point range as far as possible. Every 3kg of degreaser added can increase the alkalinity by 1 degree.
b. When the working liquid is used for a long time or the oil content exceeds 1%, the degreasing capacity will be reduced and the degreasing agent will be ineffective. At this time, it should be abandoned and updated.
