I-Hielscher Ultrasound Technology

Thuthukisa ama-Scavengers wakho nge-Ultrasonic Mixing

I-scavenger isisetshenziswa samakhemikhali esongezwe engxenyeni ukuze kususwe noma kuvimbe ukungcola nokuthengiswa kwemikhiqizo. Ukuziphendulela okuningi, izinto eziningi zokuqala zisetshenziselwa ukuqhuba ukusabela kwesigaba sesisombululo ekuqedeni. Ingxube yokugcina ihlanganiswa nomkhiqizo oyifunayo nomkhiqizo oyedwa noma ngaphezulu ongathandeki. Lapho ukusabela sekuphelile, umkhiqizo ohlangothini olungadingeki kufanele ususwe. Inqubo evamile yokususa izinto ezingadingeki kusuka enhlanganisweni yokusabela ishaqa. Ama-scavengers avame ukungezwa ngokweqile ukusheshisa ukususwa kokungcola. Ukuxuba ama-scavengers ngamandla-ultrasound engxenyeni yokusabela inikeza ubungani obuhle ukuhlakazeka ngakho-ke umkhwayizi uphuphuke ube yizinhlayiyana ezincane noma amaconsi. I-small the particle size noma droplet usayizi, indawo ephezulu yokusebenza. Lokhu kuholela ekusetshenzisweni okwedlulele ngokweqile kwamakhemikhali okuhlambalaza nokususwa ngokushesha kokungcola noma imikhiqizo engadingeki.

Ama-Scavengers avame ukusetshenziswa kuwo

  • imakhemikhali: Esikhathini sokuxazulula isigaba samakhemikhali amakhemikhali, ama-scavengers asetshenziselwa ukukhipha ama-reagents angaphezu kokudliwayo kanye / noma ama-reagents asetshenzisiwe.
  • ukuthuthukiswa kwemithi kanye nokukhiqizwa: ama-acidial asebenzayo okuhlanzeka okudingekayo ukuze izinhlanganisela zikwazi ukuveza imiphumela yazo ngokugcwele.
  • Amafutha & imboni yegesi: isib ngesikhathi sokuphuza amanzi. Isibonelo esivamile ukususwa kwe-hydrogen sulfide (H2S) ukugwema noma yikuphi ukusabela okungalungile (ikakhulukazi ukulawula ukubola).
  • i-biology kanye ne-bio-tech: isib isenzo se-nanoparticles njenge-scavenger ekhululekile ukuvikela izicubu ngokumelene nomonakalo.
Amadivayisi we-Hielscher ultrasonic amathuluzi anamandla okunciphisa usayizi wezinhlayiyana (Chofoza ukuze ukhulise!)

I-Ultrasonication iyithuluzi eliphumelelayo kakhulu lokuhlakazeka nokuqhafaza

Amandla we-Ultrasonic Mixing

Amagagasi ama-ultrasound anamandla angena emkhatsini wamanzi aphuma kuwo cavitation. Amandla okugcoba ama-cavitational ayasebenza kakhulu ukusabalalisa futhi emulsify. Ukusabalalisa usayizi omuhle, okutholakala ngokuxuba okunamandla kwe-ultrasonic, kungenziwa ukulawulwa ngokuqondile ukuze izinhlayiya ze-micron- nano-size zisetshenziswe kalula. Ubukhulu obuncane bezinhlayiyana zezikhwama kanye nokusabalalisa kwazo kuholela ezinhlakeni eziphezulu eziphezulu, okusho ukuthi indawo ebonakalayo ekhuthele kakhulu ukubopha ukungcola ukuze ibasuse engxenyeni yokusabela.

Izinzuzo ze-Ultrasonic Scavenging

Nge-dispersion ephumelelayo ye-ultrasonic, umkhwabanisi angasetshenziswa kancane. Amandla e-ultrasound ahlakazeka futhi asakaze izinhlayiya noma amaconsi ngosayizi omuhle kakhulu, ukuze amandla asetshenziselwayo asebenze. Ngakho-ke, ukusetshenziswa okuningi ngokweqile kwama-reagents we-scavenger kugwenywe. Lokhu kusindisa umkhwabanisi futhi kusiza ukususwa kwemikhiqizo emihle.
I-Ultrasonic esisize ukukhwabanisa ivumela ukuhamba okuphezulu nge-parallel synthesis nokuhlanzwa. Lokhu kwenza inqubo yakho iphumelele ngokwengeziwe futhi ithuthukise ikhwalithi yomkhiqizo. Izinzuzo ezengeziwe zivela ekutheni ukuklahla kuyindlela ebalulekile ekuchithweni kwe-chromatography yesikhumba kanye noketshezi lwe-liquide-liquid.
Ukuxubana kwe-Ultrasonic kunomthelela kuzo zonke izinhlobo zama-scavenger, njengama-scavenger eqinile (isib. Ama-powders, ama-gel, ama-polymers ama-scavenger, ama-resins ama-scavenger), nama-scavengers anesisindo.

    Londoloza umkhwabanisi ngokugwema ukusebenzisa okuningi ngokweqile kwama-reactants!

I-Sonication ye-Batch noma iNonication Inline

Izinqubo ze-Ultrasonic zingasetshenziswa njengendlela ye-batch kanye nemodi eqhubekayo yokugeleza. Ikakhulukazi emincintiswaneni encane, isib. Ukunikezwa ngamasampuli kanye nezinkampani ezincane zokukhiqiza, inqubo ye-ultrasonification ingenziwa kalula ku-beaker noma i-batch. Kodwa-ke, ukuhamba kwevolumu ephezulu kuyindlela yokunciphisa i-inline ekhuthazwayo ukuqinisekisa ukuthi ngisho nemiphumela yenqubo ehambisanayo. Ngokuvumelana nomsakazo wevolumu, i-Hielscher inikeza ububanzi obubanzi be-reactor flow cell ultrasonic.

Inqubo Yezinyathelo Zokukhishwa Kwe-Ultrasonic Esizayo

  • 1. Lungiselela ukusabela kwesibindi bese uvumela ukuphendula izinto ngokuphelele. (Qaphela ukuthi i-ultrasound ikhuthaza ukusabela kwamakhemikhali! Kungaba usizo ukukhulisa ingxube yokusabela futhi ngesikhathi sokuqala.) Ngemuva kokuphendula, ikhambi liqukethe umkhiqizo wokugcina kanye nemikhiqizo engafuneki. Engeza umkhwayizi ozikhethelayo
  • 2. Engeza umkhwabanisi futhi ulungiselele isikhala esingaxubekile esine-pre-mix noma emulsion. Ngemuva kokumiswa kwe-slurry / emulsion, velisa ingxube.
  • 3. Uma ukusabela okuqothulwayo kuqediwe, i-by-imikhiqizo iboshelwe futhi ingasuswa noma ingahlala engxenyeni yokusabela njengoba ngenxa yokuzibophezela kwayo nomqashi. Ukuhlanzwa kungenziwa ngokuqoqa umkhiqizo ohlanzekile ngokuhlunga, centrifugation noma ngokususa i-eyedropper / pipette.
I-ultrasonic transducers i-UIP500hd (500W), i-UIP1000hd (1000W), ne-UIP15000 (1500W) ngamaseli wegeleza ngezinqubo zokuqhubeka zomsindo we-sonication
