A, ballpoint pen use common sense 1 ball bead closing process: Ballpoint pen ball head and ball seat composition (pictured) explain, specify here is the ball, here is the ball seat, ink channel has five ditch. The ball is placed on the ball seat, the ball seat closes, and the ball is wrapped so that the ball does not fall out and the writing process is completed.
Ballpoint pen writing principle: The ball can rotate freely in the ball seat. The ink of the ballpoint pen flows through the five grooves in the ball seat to the ball. When the pen is writing, the friction force drives the ball to rotate, so that the ink flowing to the ball is continuously transferred to the writing.
3 Ball Point Pen's Ocurring Causes When writing a ballpoint pen, a part of the ink is transferred from the ball to the writing. Look at the ball after the ball has been transferred and turn white. The other part of the ink will be returned to the ball seat as the ball rotates. A good tip, with the rotation of the ball, brings the ink back to the ball seat more thoroughly, and the ink is less on the outside of the ball seat head, and is relatively clean. In poor writing, most of the ink will stick to the outside of the head of the ball and cannot be brought back into the ball seat, which is what we call oiling. When writing, it is easy to contaminate the writing. Ballpoint pens need to be fluent and there are more ink outs, but the negative effect is to drop more ink. If you want to drop ink, the disadvantages are not fluent. These two situations are a pair of contradictions. How to comprehensively consider them so as to achieve the best results is the subject that ballpoint pen manufacturing has been studying. The reason why the “Platinum†brand ballpoint pen is written smoothly, does not contaminate writing materials, and has a long service life is highly praised by users. Efforts in this area cannot be underestimated.
4 ballpoint pen pen tip caused by the impact of the situation ballpoint pen landing, such as the pen tip 90 degrees touched, then the ballpoint pen tip will not be damaged, but if the mouth Department of bruises (pictured), this will produce "oil" in this gap If the phenomenon is serious, the ball will fall off and the writing will be difficult.
5 The correct writing angle of the ballpoint pen (55°~70°) When the ballpoint pen is written, the angle is controlled to be 55° to 70°. At this time, only the ball is in contact with the paper (the ball is very hard... Tungsten carbide or Ceramics are very difficult to wear. They do not touch the writing at the mouth to ensure that the ballpoint pen can prolong its service life under good writing conditions.
6 The writing angle is too small to wear the ball seat. The ball seat material is nickel-platinum-copper or stainless steel, which is much more wearable than the ball. If it touches the written object for a long time, even if the written object is paper, the ball seat is also Can not afford to wear, it will cause the ball to fall off.
7 When writing, the pad is too thick, the tip of the writing tip touches the paper, it is easy to wear off the beads, it is recommended: 0.4 ball can not be rewritten; 0.5 ball can be a maximum of 1 copy, not more; 0.7 of the ball up to 3 It is not advisable to have more than 4 sheets, and it is best to write 75° when writing.
B. Failure of the active pencil and repair of the common fault of the activity pencil is lead core fracture. The active pencil holder is dead due to the two broken lead cores (ie, the new lead core cannot enter and exit the chuck). At this time, remove the activity. The pencil tip sleeve is used to push out the broken lead core with a needle and pick out the broken lead core at the clip head.
C. Principles and advantages of pencil structure without residual core activity (pictured) This is the biggest revolution in the activity pencil in a hundred years. The general activity pencil can not be used when the lead core is used to 12.4mm, and the residual core pencil can still be used even if the lead core is used at the last 1mm. Its main feature is the use of a double-jaw structure. The front chuck holds the leading end of the lead, and the rear chuck holds and pushes the lead.

With the core dressing method (pictured): Push open the back of one lock and then open the cover at two places. Insert the new core into A, remove the blue tape, stick one end to the opposite side of the correction tape, and then extend it in the direction shown in Figure B to C. The other end of the blue tape is affixed to the plastic core C and rotated several times, and then the lid is covered.
