2) three sheets at room temperature, are impregnated into 10min in the above-mentioned cleaning glass agent solutions of 100mL, are hung after taking-up
In on clothes hanger, naturally dry at room temperature.
3) pendulum that the sheet glass after drying is clipped in pendulum washing machine is washed on frame, it is made to keep plumbness, each sheet glass leaching
Bubble is in a beaker (250mL deionized waters);With stopwatch meter timing, sheet glass is first impregnated into 20s, then pendulum washes 3min (pendulum
The slew rate for washing instrument is set as 36 beats/min);Sheet glass is removed, continues to be hung on clothes hanger.
4) observation clothes hanger upper glass plate surface is by the percentage of water layer area coverage.
5) wait for that sheet glass after natural drying, continues rinsing test next time at room temperature.
Appreciation gist:Rinsing back glass sheet is bigger by the accounting of water layer area coverage every time, then shows the wetting of sheet glass
Effect is better.
The hydrophilic evaluation experimental of resistance to rinsing
1) newly purchase glass slide is flushed three times with clear water after cooling first with 15min is boiled in detergent, then uses acid solution
Middle immersion 1h, then clear water and deionized water is used to rinse twice respectively, it is finally placed in drying box and dries.
2) three sheets at room temperature, are impregnated into 10min in the above-mentioned cleaning glass agent solutions of 100mL, are hung after taking-up
In on clothes hanger, naturally dry at room temperature.
3) pendulum that the sheet glass after drying is clipped in pendulum washing machine is washed on frame, it is made to keep plumbness, each sheet glass leaching
Bubble is in a beaker (250mL deionizations are housed);With stopwatch meter timing, sheet glass is first impregnated into 20s, then pendulum washes 3min
(slew rate that pendulum washes instrument is set as 36 beats/min);Sheet glass is removed, continues to be hung on clothes hanger, at room temperature naturally dry.

Compatibility
Compatibility refers to that a kind of substance coexists not in certain dicyandiamide solution with another or many kinds of substance in the present invention
It will appear layering, ability that is muddy, or even precipitating.The compatibility of substance is tested by visual observation and the evaluation of turbidity test synthesis.Mesh
Depending on obtaining transparent uniform appearance, turbidity is that compatibility is good less than 5NTU, and visual finding system is layered, muddy, or even heavy
It forms sediment, turbidity is greater than or equal to 5NTU then poor compatibilities.In liquid detergent composition, different types of anion surface active
General compatibility is good between agent, can form homogeneous and transparent mixture in water.
Anion surfactant and cationic surfactant poor compatibility, positive and negative charge when mixing in water
Neutralization forms insoluble matter, and mixture is placed for a long time and high temperature placement will appear muddy, split-phase and even precipitate.
The present invention evaluates compatibility using visually test and turbidity test synthesis.Unexpectedly, present invention discover that sun from
Sub- polymer Noverite 311 and anion surfactant and amphoteric surfactant are compatible within the scope of certain proportion
Property it is good, homogeneous and transparent mixture can be formed in water, muddy or layering will not occur in long term high temperature or low-temperature storage.
