The applied characteristic of nanometer silicon dioxide (VK-SP30T) in dope:
1. Be able to bear rinse: the anti-rinse capability can be increased from thousands times to ten thousands times.
2. Resist to ultraviolet radiation: the anti-aging capabilities can improve about three times when we add some nanometer silicon dioxide (VK-SP30T) in dope.
3. Anti-pollute and auto-cleaning capability: some researches have indicated that the anti-pollute and auto-cleaning capability of paint can be improved obviously after adding nanometer silicon dioxide in dope.
4. Anti-fungus function: the surface of dope has good anti-fungus function when we add more than 0.5% of nanometer silicon dioxide (VK-SP30T).
5. Hydrophobic and antiseptic property: to add some nanometer silicon dioxide (VK-SP30T) in dope can improve the adsorbent and antiseptic property of the dope. The paint also has high compact property and can prevent ion to infiltrate effectively.
6. Transparent property: nanometer silicon dioxide (VK-SP30T) can improve the transparent property of nano-dope.
7. Rigidity: organic material can be improved as a rigid chain when nanometer silicon dioxide (VK-SP30T) particle disperse in it equably.
8. Hot stability: in UV solidify dope nanometer silicon dioxide (VK-SP30T) can improve the vitrifying temperature of gel.
9. Viscosity: nanometer silicon dioxide (VK-SP30T) can improve the viscosity of dope obviously.
Dosage:
Some experiences have proved that the rigidity, adsorbent, hot stability and anti- depositing property of dope can be improved well when we add 2% nanometer silicon dioxide (VK-SP30T).So the propositional dosage of nanometer silicon dioxide (VK-SP30T) is 0.5-2%.But some special products may add more than 10%,you should adjust the additive percent according to your system.
The method of use:
We can use several methods to disperse nanometer silicon dioxide (VK-SP30T), such as mill, cutting with high speed, ball-grind, ultrasonic and so on. The most popular and economic method is cutting with high speed .There are two ways to add nanometer silicon dioxide (VK-SP30T) in paint by this method.
1. One step method: adding nanometer silicon dioxide (VK-SP30T) in the material directly. This method is very simple and appropriate to the large quantities and single productions.
2. Two steps method: firstly, to prepare base liquid of nanometer silicon dioxide (VK-SP30T) dispersed in material with high percent. Then add base liquid to material system. Two steps method is suit for various productions.
