Specifically, step S101 is specifically included:
S1011: examine whether making material has pasting protective film;
Making material needs two-sided pasting protective film, pipe diameter be less than 200mm can single side pad pasting, negotiate to transport with supplier How the links such as defeated, storage avoid raw material from scratching;
S1012: examining the appearance of making material, check surface whether have draw damage, deform, defect, check making material Inside whether there is phenomena such as bubble, stain;
S1013: examine whether the light transmittance of making material is greater than 80 ﹪;
S1014: tearing protective film, carries out baking test, 65 ° ± 1 ° of temperature, toasts 3 hours, material is natural in baking oven Being cooled to room temperature rear can be taken off, it is ensured that ungauged regions;
S1015: cleaning the making material after baking with isopropanol, there is not allowed that finding of naked eye crackle;
S1016: the flatness of making material is examined.
In preferred embodiment, between step S101 and step S11 further include: S102: storage;To the making material after inspection It is stored according to memory requirement, flow chart is as shown in Figure 3.By taking acrylic material as an example, storage and environmental requirement are as follows: 1) warm 25 ° ± 3 ° of degree;2) 65 ° ± 10 ° of humidity;3) smooth placement can stack, and store constant temperature storeroom.
In preferred embodiment, between step S18 and step S19 further include: S103: polishing;The Water ball complete to deburring Outer surface is polished, its clear transparent is made, must not have in polishing process draw damage, it is necessary to corner angle are clearly demarcated, there is not allowed that step on side, Pit, seam trace, flow chart are as shown in Figure 4.
Specifically, step S103 is specifically included:
S1031: rough polishing first is carried out with thick waterproof abrasive paper 280#;
S1032: and then gradually fine polishing is carried out with thin waterproof abrasive paper 600#, 1200# again.
It finally can also include being packed to Water ball in above-described embodiment, protect Water ball surface so as to rear reforwarding It is defeated.
The production method of Water ball of the invention guarantees the quality of production using complete, specification production technology, produces matter Measure more stable, product qualification rate is high, extends the service life of the Water ball to complete;, and production cost has been saved, Reduce the requirement to operator.
Disclosed herein is merely a preferred embodiment of the present invention, these embodiments are chosen and specifically described to this specification, is Principle and practical application in order to better explain the present invention is not limitation of the invention.Anyone skilled in the art The modifications and variations done within the scope of specification should all be fallen in the range of of the invention protect.
