Water -based pen is a pen that is used more in daily writing supplies. It is welcomed by many consumers due to the characteristics of convenience, cleanliness, and fluent writing.Choosing a combined water -based pen can make people smoother and comfortable in the process of learning and work.Let ’s take a look at how to choose a water -based pen with Xiaobian!
Principles of water -based pen
Under the hydraulic action of the writing fluid, the writing fluid forms the handwriting through the gap between the steel ball and the nib.Mainly use the ball beads to directly contact the paper on the paper to generate friction, so that the balls are rolled in the roller, bringing out the ink or ink in the core, and the subsequent water is constantly supplemented by the atmospheric pressure.To achieve the purpose of writing.Therefore, most of the early water -based pens will drill a small hole in a place near the tail to ensure air circulation.
How to clean water
1. Pour the pollution with the laundry solution, and then dilute the white vinegar with water. Use a brush to dip the solution gently and scrub it. The dirt can be removed.
2. Gently wipe the stain with a cloth strip.
3. After soaking the stains with cold water, apply some toothpaste, and rub a small amount of toothpaste gently. If there are traces, wipe it with alcohol.
4. Boil the milk, put a towel under the clothes, and dip it in hot milk with a cotton cotton until the oil traces disappear.
5. Wipe it with gasoline and then clean it with detergent (do not soak in hot water).
How to choose a water -oriented pen
1. The choice of appearance and thickness
Determine what the appearance, what structure (plug -in or pressing), and what price you want to buy.Generally, a regular exam should be used in black, 0.5mm pens, and the size of the pen core can generally be seen from the label posted on the side of the pen.At the same time, you must choose the pen that suits you best according to your actual hand -holding pen. Too rough or too thin will affect your writing experience.
2. The choice of pen tip
The shape of the pen head is generally divided into bullets, needle ducts, and semi -needle.The bullet type is suitable for making a thicker pen head. The needle duct type is suitable for making finer pen. The semi -needle is between the bullets and the needle tube: the tip of the pen can be as thin as the needle tube, and the end of the pen head and the sub -warheader canThe tail is the same.The semi -needle type can create a relatively thin pen.
3. Observe ink
Observe whether there are enough ink (generally two -thirds, or more), and whether there is a water break in the middle.You also need to observe whether there are bubbles in the ink. If there are many bubbles and very obvious, it means that the manufacturer does not control well. This kind of pen cannot be bought.Finally observe the ink color.Looking at the ink color is actually choosing the writing color of the pen you need.
4. Check whether the pens and parts fit
If you are inserted, you must first check whether the pen lid is fitted with the pen.The size of the pen cover is not suitable, it is difficult to protect the pen.If it is a pressing pen, you must first check whether the press function is normal and whether there is a protective wax.Then, pick up the pen and shake it gently, and feel whether there is a collision sound.
This step is basically the last step.Wash the pen to write on the paper. When writing, pay attention to listening to the sound of "rustling".If so, it means that the pen beads are not enough to do and cannot be purchased.Secondly, there is a phenomenon of water breaking in observation, and whether the handwriting edges are smooth. Without water, the handwriting side is preferred.
