Accompanying drawing explanation
Fig. 1 is the flow chart of a kind of PC denture making procedure of the present invention processing method.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
Embodiment one
A kind of PC denture making procedure processing method of the present invention, includes following steps: step S01, and the qualified rear start of initial workpiece is produced, and is installed by the PC glue part baking tray produced, after filling a baking tray, baking tray is transported to baking box place; Step S02, puts into baking box by the baking tray filling PC glue part; And recorded the time that baking tray puts into; Check before leaving whether normal heating of baking box be, and baking box annealing temperature is set to 120 DEG C; Step S03, oven cooking cycle, after 110 minutes, opens oven door, wears heat insulation facility and is taken out in baking box by baking tray; Place at room temperature after taking out baking tray, allow baking tray and the PC glue part Temperature fall in dish to room temperature; Step S04, gets the PC glue part after annealing, PC glue part is immersed in the receptacle that carbon tetrachloride solution is housed completely, takes out the PC glue part of test after immersion with instrument; Whether step S05, visual detection PC glue part has stress cracking phenomenon.
In described step S03, after taking out baking tray, place at room temperature 25 minutes.In described step S01, PC glue part needs smooth being placed on baking tray.In described step S04, soak time is 235 seconds.In step S05, occur that the PC glue part of cracking is taken out, again process.
PC plastics formal name used at school is Merlon, and be the one of plastic material, melt temperature is high, and viscosity is high, is used for industry and waits in production.Merlon is daily common a kind of material.Due to its water white transparency and excellent impact resistance, daily common application has laser disc, lens, water bottle, bulletproof glass, the glass, headlight etc., animal cage pet cage etc. of goggles, bank's bullet proof.Polycarbonate is also the one of the material that notebook computer casing adopts, its raw material is oil, polyester slice particle has just been become after polyester slice factory process, finished product has just been become again through plastic molding and processing plant's processing, from the angle of practicality, its heat dispersion is also better than ABS plastic, and spread heat is more even.Use this material to be exactly FUJITSU more significantly, be all use this material in a lot of model, and be that full shell all adopts this material.No matter from surface still from touch sensuously, PC-GF material sensation similarly is all metal.If do not identified in notebook computer, single carefully not going viewed from outer surface is observed, and may think it is alloy thing.Merlon is also used to the faceplate making moonman.The iPod music player of Apple and ibook notebook computer casing also use Merlon to make.Due to the clear of it and toughness, the producer and the purchasing agent of food reserves goods like polycarbonate.When comparing polycarbonate as lightweight and highly non-friable with silicon soil glass.Polycarbonate is used for disposable plastic water bottle and reuses plastic water bottle.
Baking box can not near wall.Put steadily, well-ventilated.Oven temperature is gone up and to be opened baking box safety door descendant after more than 40 degree baking box is too near beyond this point, in order to avoid scalded by heat wave.In baking box, get the product having moved back fire necessarily needs equitemperature to be reduced to room temperature or could picking with protective gloves.Have in bake process and safety alarm occurs to be the first action be logical administrative staff after cutting off the electricity supply and to show up process.There is baking box inside and occur that peculiar smell also needs to notify that administrative staff process after powered-down immediately.Chemical solution carbon tetrachloride can not with skin contact, special messenger operate.
