Product of the present invention has following advantage to existing projection writing plate:
1. hardness is high (being not less than 6H), lacquer painting is difficult to scratch the integrality that keeps writing surface when beneficial to writing, and city
Plate on face typically only has 1-3H hardness, and plate face has been easy to cut in long-term writing process, is unfavorable for writing
2. chemicals-resistant corrosivity is high, hardness is tested after being soaked 72 hours in butanone solvent immediately and is not less than 3H, this
Clipboard is conducive to be kept in being contacted for a long time with writing ink not by ink etch, so as to influence to wipe the writings of on the market
Plate is soaked after 2 hours in butanone solvent, and hardness only has 2B, and such clipboard one is easily to be written nib scuffing, and two are
Writing ink is easy to etch and enters clipboard, has a strong impact on wiping
3. weather resistance is excellent, pass through GB/T23987-2009《The artificial weathering aging of paint and varnish coating is exposed to the sun cruelly
It is exposed to fluorescent UV and water》Loss of gloss is 5% after 800 hours, no discoloration and other any anomalies；Do not influence to write and wipe
Wipe, this is beneficial to writing and wiping of the plate during long-term use；And clipboard on the market loses under similarity condition now
Light is 33%, and color xanthochromia has a strong impact on wiping, and such plate can gradually influence the wiping of ink during long-term use
Wipe
4. wearability is good, with being wiped 20,000 times under 1KG gravity with having soaked butanone solution absorbent cotton, film is complete, not shadow
Ring writing and wipe, this is beneficial to the long-term normal writing and wiping onboard of lettering pen；Plate on the market typically can wipe 1
Thousand times film just returns show-through
