(Summary description)Now gel pen holder generally used AS plastic or TPR AS plastic characteristics than polystyrene has higher impact strength and excellent heat resistance, oil resistance, chemical resistance, such AS it can be very good resistance to some polystyrene stress cracking hydrocarbons and elastic modulus is one of the higher existing thermoplastics AS for styrene - propylene eyeball copolymer, not easy to produce internal stress cracking transparency is very high, its softening temperature and impact strength than PS high physical and chemical properties SAN (AS) has a strong ability to withstand load resistance chemical reaction resistance thermal deformation characteristics and several stability SAN(AS) adding glass fiber additives can increase the strength and thermal deformation resistance, reduce the coefficient of thermal expansion SAN(AS) vikas softening temperature is about 110 C load flexural deformation temperature is about 100 C SAN(AS) shrinkage rate is about 0.3-0.7% SAN(AS) is a hard and transparent Styrene makes SAN(AS) hard, transparent and easy to process; acrylonitrile ingredients make SAN(AS) with chemical stability and thermal stability injection molding process. The AS processing temperature is generally in 200-250 C is appropriate. The material is easy to absorb moisture, before processing to dry more than hours, its liquidity is slightly worse than PS - point, so the injection pressure is slightly higher if stored improperly, SAN(AS) Some hygroscopic characteristics suggest drying conditions of 80 "; 2-4 hours melting temperature 200-270 C. If I thick-walled products are added, you can use the melting temperature below the lower limit mold temperature 40-80 C for enhanced materials, the mold temperature should not exceed 60 C cooling system must be well designed, because the mold temperature will directly affect the appearance of the product shrinkage and bending Injection pressure 350-1300 bar Injection speed recommended high speed injection runner and sprue all conventional sprue can be used the sprue size must be appropriate to avoid lines, spots and gaps.

What is the method of removing gel pen stains? How to erase gel pen handwriting?

1. Alcohol: As an organic solvent, alcohol can easily remove the ink of the gel pen. If it is still on the clothes, the ink and water mark of the gel pen can be erased directly with alcohol cotton 2. Acetone: Acetone as an organic solvent can easily remove the marks of gel pens. You can dip a cotton swab in acetone, and rub it back and forth on the marks of gel pens to remove 3. Nail polish remover: the nail polish remover used by girls to remove nail polish is also easy to remove ink marks in the pen 4. Detergent: not the pursuit of too clean, in fact, you can use detergent repeatedly to wash ink traces or traces will be easy to remove.

The development of gel pens in China.

As far as China is concerned, in the mid-1990s, an enterprise in Wenzhou began to mass produce gel pens. At that time, the quality was unstable due to the process being not very mature and other reasons, so it failed to form a domestic market. After that, Ningbo Beifa Company used imported ink and floating plug grease imported from the pen tip. After that, changlong love le Meicheng Road Platinum Baineng Morning light and other powerful pens: enterprises have begun to produce gel pens. Its nib ink also relies on imports at present. The output of China's gel pen has reached 10 More than 700 million of them are exported. Gel pens and water-based pens account for more than 35% of the ballpoint pen production. According to the market development trend, it seems that in recent years the output of the gel pen will continue to climb and according to the information from the pen making association: in order to strengthen the quality management of the neutral pen in Our country, to ensure the quality of the product, according to the requirements of the manufacturers and consumers of the product, by the national pen making standardization center, in 2001 Formed by Ningbo in October Mr Group co., LTD. Wenzhou hobby hunan co., LTD Qingdao rectify stationery co., LTD. Ningbo into road style daily crystal manufacturing co., LTD Shanghai forword round bead pen co., LTD Shanghai beauty co., LTD Shanghai seven companies such as China and South Korea the morning stationery manufacturing co., LTD., established the gel pen standard The drafting team, after more than half a year of efforts, China's neutral pen standard has been approved at the end of April 2002, and reported to the Light Industry Federation and the State Bureau of Quality and Technical Supervision for approval in May, so far, China's neutral pen industry has laid a good foundation, further development has become an inevitable trend.
