热转印:用页式打印机将热转印图案打印到热转印纸上,然后用烫画机压印。
热升华:用热升华打印机将热转印墨水打印到热升华纸上,然后用烫画机压印。
普通打印机应用在热转印行业就是热转印打印机,就这么简单。
但是,他们的效果是不同的。打印出来的效果不仅受像素的影响,还有打印机的分辨率决定,打印机的质量不好,用再清晰的图像也是白搭。如果想让你的产品色彩更丰富,质量更高的话,推荐你选择OKI的C711wt或者C941dn,这两款都有白色打印功能,分辨率超高,性能很不错。
目前市面的热转印打印机的工作原理主要有两种:压电式打印和热发泡原理。爱普生打印机就是采用压电式打印,压电式打印机因为只是改变机械压力不会使热转印墨水化学性质发生改变,它是通过电脑控制改变打印头微小压电陶瓷片电流大小而使之产生不同的压力把墨水从喷嘴喷出来形成不同深浅的图像;适合做热转印。EPSON系列的R210/230/270/290/Me系列等是最适合用于个人热转印的打印机。

The piezoelectricity ceramics have quickly respond, the energy densityhigher characteristic, in domain and so on precision machinery,speaker, absorption of shock noise reduction obtained the widespreadapplication, in the intelligent structure, its function may notsubstitute in particular But the traditional pressure ceramicsactually have the obvious insufficiency, because actuation strain toosmall, is very difficult to satisfy the actual project application theneed In order to obtain the bigger actuation strain, the peoplestudied the many kinds of piezoelectricities actuation part, likedouble curved piezoelectricity driver, " Mooine" Brass -PZTcombination driver, kind of alone stone structure actuation part andso on But these all belong to the machinery to enlarge the mechanismthe application, while obtains a bigger strain, also reduced thedriving influence, from essentially solves the problem by no means
The piezoelectricity ceramics application is extremely widespread, themost typical application is the buzzer and the security alarmapparatus, after 素坯 rolls over the ceramics the image formationpaper same thin slice to fire, makes the electrode in its both sides,then the polarization, such ceramics had the piezoelectricity, then itwith the tinsel agglutinated again in together, made a buzzer Whenelectrode circular telegram, the piezoelectricity ceramics because thecounter piezoelectric effect has the vibration, makes sound which theperson ear may hear Through the electronic circuit control, may havethe different frequency vibration, thus makes the different sound, thebuzzer most early uses on the electronic toy, now also uses in thefire engine, the ambulance, the safe cabinet and so on place takes thealarm apparatus Can transform using the piezoelectricity ceramics themechanical energy the electrical energy the characteristic, but alsomay make " Ceramic ear " In front of the common earthquakebecause the earth's crust interior unusual games sends out 地声, theceramic ear may the sound which hears turn the electrical signal inputcomputer, like this may 地声 forecast the earthquake through themonitor
The sound motor is in the piezoelectricity ceramics application anoticeable new domain It is uses the piezoelectricity ceramics thecounter piezoelectric effect, directly transforms the electricalenergy the mechanical energy output not to need the magnet coil thenew electrical machinery, compares with the ordinary electromagnetismmotor, it has the structure simply, starts, the volume quickly young,the power loss is low and so on the characteristic Moreover, becauseit is directly transforms from the electrical energy into themechanical energy but does not transform through themagnetoelectricity, therefore, does not have the magnetism disturbancenot to fear the magnetism disturbance It also may the low speedmovement but not use the reduction gear This kind of miniatureelectrical machinery in the aviation, astronautics, the precisionmachinery, the instrument measuring appliance, the automatic control,the robot, the scanning electricity mirror moves slightly, thephotographic camera automatic focusing, the magnetic head moves, themotor vehicle windshield wiper and the electrically operated switchglass and so on many areas of technology has the broad applicationprospect
The former piezoelectricity ceramics were by several microns thepolytropism material which was composed to several dozens micronsmulti- domains crystal grains, the size have not been able to meetthe needs Reduces the particle size to an Asian micron level, mayimprove the material the workability, may do the substrate is thinner,may enhance the array frequency, reduces the transducer array theloss, enhances the component the mechanical strength, reducesmultilayered component each level thickness, thus reduces the slavingvoltage, this to enhances folds the level transformer, the brake allis beneficial Reduces the particle size to have the above so manyadvantage, but simultaneously also brought reduced the piezoelectriceffect the influence In order to overcome this kind of influence, thepeople changed the traditional doping craft, makes 细晶粒 thepiezoelectricity ceramics piezoelectric effect to increase to and粗晶粒 the piezoelectricity ceramics suitable level Nowmanufactured 细晶粒 the material cost to be possible to competewith the ordinary ceramics In recent years, the people carried onwith 细晶粒 the piezoelectricity ceramics have cut grind theresearch, and manufactured some high frequency transducers, the microbrake and the thin buzzer (porcelain piece 20-30um is thick), hasproven 细晶粒 the piezoelectricity ceramics superiority Along withthe nanotechnology development, 细晶粒 the piezoelectricity ceramicmaterial research and the application development was still theshort-term hot spot Moreover, the piezoelectricity body is the launchand the receive ultrasonic wave ideal material When the alternationelectrical signal function to the piezoelectricity body, has thedeformation because of the counter piezoelectric effect, gets off anaircraft 电耦合 the resonance in the suitable frequency to launchthe ultrasonic wave, thus the constitution launch pokes head in, butwhen the ultrasonic wave does uses in the piezoelectricity body, as aresult of the undulation mechanical power function, can because of thepiezoelectric effect but in the piezoelectricity body correspondingsurface produce the electrical signal to output, the constitutionreceive pokes head in Pokes head in with this kind to be allowed tomanufacture the ultrasonic flaw detector survey object interior theflaw, but also may make the supersonic microscope, the supersonicthickness gauge and so on
压电陶瓷片的工艺流程:
配料--混合磨细--预烧--二次磨细--造粒--成型--排塑--烧结成瓷--外形加工--被电极--高压极化--老化测试。
1、配料:进行料前处理,除杂去潮,然后按配方比例称量各种原材料,注意少量的添加剂要放在大料的中间。
2、混合磨细:目的是将各种原料混匀磨细,为预烧进行完全的固相反应准备条件一般采取干磨或湿磨的方法。小批量可采取干磨,大批量可采取搅拌球磨或气流粉碎的方法,效率较高。
3、预 烧:目的是在高温下,各原料进行固相反应,合成压电陶瓷此道工序很重要。会直接影响烧结条件及终产品的性能。
4、二次细磨:目的是将预烧过的压电陶瓷粉末再细振混匀磨细,为成瓷均匀性能一致打好基础。
5、造粒:目的是使粉料形成高密度的流动性好的颗粒。
6、成型:目的是将制好粒的料压结成所要求的预制尺寸的毛坯。
7、排塑:目的是将制粒时加入的粘合剂从毛坯中除掉。
8、烧结成瓷:将毛坯在高温下密封烧结成瓷。此环节相当重要。
9、外形加工:将烧好的制品磨加工到所需要的成品尺寸。
10、被电极:在要求的陶瓷表面设置上导电电极。一般方法有银层烧渗、化学沉积和真空镀膜。
11、高压极化:使陶瓷内部电畴定向排列,从而使陶瓷具有压电性能。
12、老化测试:陶瓷性能稳定后检测各项指标,看是否达到了预期的性能要求。
