Ukuhlolwa kwe-Cavitation Erosion (ASTM G32-92)

Ukulawulwa kwe-ultrasonication okulawulwayo futhi okukhiqizayo kuyadingeka ukuze kwenziwe ukuhlolwa kokuguguleka komhlabathi ngokuhambisana I-ASTM Standard G32-92. Amadivayisi we-Hielscher ultrasonic angasetshenziselwa ukuhlolwa kokuguguleka okuqondile nokungaqondile kwamasampuli.I-Hielscher ikhiqiza amaprosesa e-ultrasonic, anakho imvamisa ehleliwe (isib. 20kHz) kanye no amplitude adjustable. Amadivaysi anjalo e-ultrasonic angasetshenziselwa ukuhlolwa kokumelana nokukhuphuka kwempahla ngokusho kwe I-ASTM G32-92.
Ukuhlolwa kwe-cavitation Erosion akugcini ekucacisweni kweleveli ye-ASTM G32. Ngemininingwane eminingi ngokuhlolwa kwegodi yokuguguleka, sicela uchofoze lapha!

Ukusetha okujwayelekile (isithombe esifanele) ukuhlolwa kokukhukhula kuqukethe:

• generator ultrasonic
• transducer ultrasonic
• (booster uphondo)
• i-sonotrode
• isitsha esineziphuzo (ehlile) isitsha esiphuthumayo

Uma kwenzeka cavitation ngqo, isampuli sinamathele kuphuzu le-sonotrode. Uma kwenzeka cavitation engaqondile ukuhlolwa, isampula ibhekene ne-sonotrode ebangeni lika-0.5 kuya ku-0.7mm kusuka enkampini ye-tip sonotrode.

Umswakama ngamanzi acwecwekile ku-25 ± 2 degC ngokucindezela okukhulu.

Ukuze uthole imiphumela enembile kubalulekile ukugijima kumakhilomitha athile, isib. Ku-50 micron. Ama-processors ama-Hielscher ultrasonic aqaphele amplitude yemishini njalo 1/20000 yesibili (20kHz). Lokhu kuqinisekisa, ukuthi isampula ivuliwe ku amplitude enembile ngesikhathi sokubeletha esigcwele.

Amadivayisi UIP500hd, I-UIP1000hd futhi I-UIP2000hd kufanelekile I-ASTM G32-92 ukuhlolwa. Singahambisa ngayinye yalezi zinyunithi ngokunembile amplitude isilinganiso protocol we amplitude mechanical at the tip sonotrode. Sincoma ukusebenzisa lawa madivayisi nge-sonotrode BS2d22 (ububanzi obungama-22mm) kanye ne-stand ST2.
