Liquid chalk effect

The use of liquid chalk is very simple, with the same basic whiteboard pen. However, its environmental protection, absolute cleanliness is whiteboard pen with ordinary chalk or so-called clean chalk can not match! To say the actual use of the effect, it involves several aspects, one whiteness, one is erasable, is it good to write a good rub! This is the crux of liquid chalk can really replace ordinary!

Because the liquid chalk ink is made of resin solvent mixed with titanium white powder, it will certainly appear a little fading after drying. If the whiteness after fading can ensure the visibility of 10 meters, then you can ensure the students to see clearly! If the faded color is more serious, then it is not a qualified product. Erasable mainly after drying can be erased in a few days can be erased. These are some of the basic use of key issues. Then there are a lot of people that need to replace the blackboard, foil inconvenient, I hope all the blackboard material can be used directly. Here is a misunderstanding: ordinary chalk is powder, you can have roughness, friction required to ensure that the writing firm on the blackboard. But the liquid chalk is a liquid, if the roughness of the blackboard is too high, fine particles will remain in the rough layout after the ink is dried, resulting in inconvenience of wiping. It can also damage the nib. It's like you write a word on a blackboard with a whiteboard pen. So, what product is equipped with what layout is certain, can not be generalized!

In general, liquid chalk is a trend that is environmentally friendly, non-toxic, harmless and dust-free, and has been favored by most schools, teachers and students alike. Of course, the price will be slightly higher, but this will not be the promotion of liquid chalk this new environmentally friendly products barrier! If you count on the harm to the chalk generation (teachers and students health, audio-visual equipment damage, etc.), then the price is actually very cheap. Or lower than ordinary chalk.
