The erasable ballpoint pen has been in production and production in China for more than 40 years. I have been in contact with this project for more than ten years. In the past ten years, I have been focusing on writing, and I have been paying attention to the development and prospects of the erasable pen in the whole industry. I have found many problems and it is difficult to popularize, which limits the production capacity and the development of the industry. I came up with an idea of ​​not admitting defeat. I started to study the production of erasable refills in January 2007. It took more than a year to go through thousands of tests, in addition to balancing the erasability, lubricity and writing lines. In addition to the various contradictions between the sexes, a lot of research and research on the storage stability of the erasable ink has been made. The advanced equipment and materials at home and abroad have been selected to make the ink storage stability, pen performance and lubrication of the erasable ballpoint pen. Sex, line continuity, and refill storage stability have achieved good results. Solved the problem of the erasable pen "good to write, not easy to write". Our erasable ballpoint pens have achieved the following six basic conditions:
1. Good hand feel, smooth writing, lubrication, no pitting
2. Writing distance is above 800m, and there is no broken line or line
3. Good erasable effect, no obvious marks
4. After 48 hours of temperature test at -20 ° C ~ 50 ° C, writing normal ink
5. No harmful substances such as heavy metals
6. Shelf life is more than one year
In December 2008, our erasable ballpoint refills passed the requirements of the European Union EN7l-3 standard and the American ASTMF963-03 standard. In the national light industry fountain pen, ballpoint pen quality supervision and inspection center, the longest erasability of the line The writing length of the ballpoint pen refill is 1806m, there is no broken line, and there is no phenomenon that the stitches become light or unmarkable, which ensures the normal ink output, and the writing feel is particularly good, and the writing is smooth, lubricated and has no pitting.
We use international standards in the process of producing erasable ball-point refills. We must ensure the stability of product quality, so that substandard raw materials are not put into production, substandard products that do not meet the standards will not continue processing, and substandard products will never be processed. Ex-factory, to ensure the continuous improvement of product quality, truly improve the quality of the erasable ballpoint pen.
I am still not satisfied with the integrity of the erasable pen. I think there is still a lot of room for improvement in the quality of the erasable ballpoint pen. In more than a year, I will continue to study and improve the cooperation between the pen and the ink. Improvement.
In May 2010, the day of the World Expo, my refills have received the SGS report on export safety inspections in Europe and America. That is to say, the current erasable pen has already obtained the passport to the world, and this time it has completed me. a wish. However, in the future production work, I will continue to work hard to make our erasable pens more perfect.
