I-Hielscher Ultrasound Technology

I-Ultrasound Yokuhlakaza nokuGaya: I-Paint & Ama-pig

 

  • I-ultrasound yamandla iyaziwa kakhulu ngokugaya kwayo okukhulu futhi okulawulwa ngokuqondile nokusabalalisa imiphumela.
  • Ama-ultrasonicators wezezimboni ahlinzeka ngokusabalalisa usayizi wezinhlayiyana ezincane ngokulingana kwe-micron- nano-range.
  • Ama-ultrasonicators asezimboni enza inqubo ye-viscosity ephezulu kakhulu kalula futhi agcwalise ukuxuba, ukuhlakazeka, ukuguqulwa kwamatshe nokugaya.

 

 

I-Paint Manufacturing ne-Ultrasound

Thuthukisa ama-Paints akho, imibala nemidwebo nge-Sonication:

I-Hielscher Ultrasonicators yindlela yokwenza amandla ekwazi ukuguqula nokusabalalisa i-nano-izinhlayiya. (Chofoza ukuze ukhulise!)

Ukuhlakazeka kwamandla we-TiO2 nge-ultrasonics.

  • Ukubunjwa: Kungakhathaliseki ukuthi i-viscosities ephakeme, imithwalo yezinhlayiya eziphezulu, i-aqueous- noma i-solvent-based – kanye nama-ultrasonicators asezimboni ze-Hielscher ozokwazi ukucubungula noma yikuphi ukubunjwa.
  • Micron- ne-Nano-Size: I cavitational Amandla e-shear aphezulu ayanciphisa izinhlayiya ezincane zezinhlayiyana zama-diameter futhi anikeze umfaniswano ukuhlakazeka.
  • Izakhiwo ezibonakalayo: Ukuze uthole izakhiwo ezifanele zokukhanya, usayizi wezinhlayiya ze-pigment kufanele ulawulwe. Ngokuvamile, i-opacity ihambisana nobungqimba bezinhlayiyana: i-fiber isayizi yezinhlayiya, i-opacity eyengeziwe. Isibonelo, TiO2 iqondiswa ngokukhethekile ebunjini bezinhlayiyana eziyi-0.20 kuya ku-0.3 micron, okulinganiselwa okulingana nengxenye yengxenye yobude bokukhanya. Ultrasonication inciphisa i-TiO2 i-pigments ibe ngosayizi wabo omkhulu, ukuze kutholakale ukufihla okuphelele.
  • Izingxenye eziphezulu zokusebenza: Ubukhulu bezinhlayiyana ezincane kubangelwa ukugcwala umbala omkhulu, ukungafani kombala nokuzinza. Ama-ultrasound aqinile, kodwa alawulwa ngokuqondile avumela ukukhiqiza ama-nano-particle modified and functionalized, njengezinhlayiya eziphekiwe, SWNTs, Ama-MWCNT kanye nezinhlayiyana ze-shell-shell. Izinhlayiya ezinjalo zibonisa izici ezihlukile futhi ziphakamisa ukudweba noma ukugqoka amazinga ezingeni elisha lekhwalithi kanye nokusebenza (isib. Ukumelana kwe-UV, ukumelana nokuqina, amandla, ukubambelela, ukumelana nokushisa okuphezulu, i-infrared nokubonakaliswa kwelanga).
  • Izingxenye eziguquliwe: Izingulube eziguquguqukayo ezisezingeni eliphezulu zine-viscosity ephansi kakhulu ekulayweni kwe-pigment high (2.5cP ku-10% solids), ukusimama okukhulu kokumiswa nokuhlanzeka okukhulu
I-ultrasound enamandla iyindlela ethembekile yokusabalalisa nokugaya izingulube zezingubo eziphezulu & imibala. (Chofoza ukuze ukhulise!)

I-Ultrasonic Paint Processing

I-ultrasonics yamandla okugaya, ukugaya nokuhlakazeka kwezingulube, upende nemibala. (Chofoza ukuze ukhulise!)

Sebenzisa ultrasonics ekukhiqizeni

 

  • ukufakwa kokugcina
  • i-master batches ye-pigment paste
  • ukuhlanza izinhlayiya emva kokugaya okuvamile

 

 

Ukuze kwenziwe upende, izingxenye ezifana ne-pigments, izibophezelo / amafomu efilimu, ama-diluents / solvents, ama-resins, ama-fillers nezithasiselo kufanele zihlangane ndawonye zibe ukwakheka okuhambisanayo. Ama-pigments yiyona ingxenye yokunquma enikeza umbala wayo. Okubaluleke kakhulu i-pigment emhlophe yi-TiO2, okudingeka ilandelwe ku-a usayizi wezinhlayiyana ezinhle phakathi 0.2 kanye ne-0.3 microns ububanzi ukuze kuboniswe ibanga elifunayo lobungcweti, ukukhanya, i-opacity kanye nenkomba ephakeme kakhulu yokubheka. I-ultrasonic shear force ihlinzeka nge-deaggomerom ephumelela kakhulu futhi esebenzayo namandla kanye nokuhlakazeka kwe-TiO2 izinhlayiya (bheka ishadi ngezansi).
I-Ultrasonic Ukukhokha futhi Ukuhlakazeka kuthonya ikhwalithi yepende ekuthuthukiseni amandla ayo ombala, ubuningi, ubuhle bokugaya, ukusabalalisa kanye ne-rheology.

ultrasonic nizihlakaza & Izimo zokugaya

Ikhwalithi yamaphoyinti nezingubo zixhomeke ekuhlakazekeni kwe-pigment. I-Hielscher Ultrasonics inikeza imishini yokugaya nokukhwehlela okuphumelelayo yokusabalalisa upende, ikakhulukazi uma kwenziwa ama-pigment ephezulu. Indlela yokwenza ultrasonic Dispersers ukukhokha & ukugaya, ukuguqulwa kwamanzi kanye nokusabalalisa izicelo kubuye kusekelwe esimisweni somswakama esakhiwe yi cavitation ultrasonic. I cavitational amabutho adingekayo ukuze kuhlukaniswe izinhlayiya zikhiqizwa ukungafani okukhulu kwezingcindezi, izindawo ezishisayo zendawo kanye namajetshi ahlanzekile, okuphumela ekuqhekekeni kwezinhlayiyana ngokushayisana kwe-particle.
Ama-ultrasonic dispersers asezimboni ezifana ne- UIP16000 unamandla okucubungula imifudlana ephakeme yamanani wezingubo kanye nezingubo zokugqoka.

Ividiyo ikhombisa ukusatshalaliswa kwe-ultrasonic ngombala obomvu kusetshenziswa i-UP400St ngenhlolokhono ye-S24d 22mm.

Ukusakazwa kombala obomvu we-Ultrasonic usebenzisa i-UP400St

Ukuhlakazeka kweNanoparticles

I-Ultrasonic ukugaya futhi ukuhlakazeka ngokuvamile kuyindlela kuphela yokucubungula izinhlayiya ze-nano ngokuphumelelayo ukuze uthole izinhlayiya eziyinhloko. Ubukhulu obuncane bezinhlayiyana eziyinhloko bubangelwa endaweni enkulu futhi kubumbana ngokuboniswa kwezici zezinhlayiya eziyingqayizivele nemisebenzi. Ngesikhathi esifanayo, ubukhulu obuncane bezinhlayiyana buhambisana namandla aphezulu okugubha okwehlukumezeka kakhulu nokusebenza kabusha, ukuze i-ultrasonic enamandla Ukuhlakazeka amabutho kudingeka ahlakaze izinhlayiya ze-nano ngokuvumelana nomumo.
Ngaphezu kwalokho, ukwelashwa kwe-ultrasonic yangaphakathi kungashintsha izinhlayiya ze-nano eziholela ngcono ukuhlakazeka, ukuzinza ukuzinza, i-hydrophobicity nezinye izici.
Abacwaningi baye batusa indlela yokuhlakazeka kwe-ultrasonic yezinhlayiya ze-nano njenge ikhambi elikhethiwe, “ngoba indaba ehlakazekile yindlela ye-ultrasonic ihlanzekile kakhulu kunalokho eyenziwe yi-bead milling”[Kim et al. 2010].

I-ultrasonic dispersion technique inezinzuzo eziningi uma kuqhathaniswa nobuchwepheshe bendabuko bokugaya njengethathu-roll, ibhola noma imishini yemidiya. (Chofoza ukuze ukhulise!)

Ukuhlakazeka kwe-Ultrasonic kunezinzuzo ezibalulekile ngokumelene namasu okugaya okujwayelekile
