Silica inoshandiswa mumasango akasiyana siyana nekuda kwekupesana kwayo, kusimbisa kwemagetsi uye kukwidziridzika kwakakwirira. Ultrasonic kupararira kunobatsira kuvhura iyo inogona kuitika yeSilica nekuvandudza mhando yekupararira.
Silica application
Silica (Sio2) is aimaFun det ceramic zvinhu zvinoshandiswa mumaindasitiri akasiyana siyana kuti vagadzirise nzvimbo uye michina yezvivakwa zvakasiyana siyana. Iyo inoshandiswa seye filler, performance inowedzera, rheology modifier kana yekugadzirisa rubatsiro mune akawanda zvigadzirwa zvekugadzira senge pendi uye huku, maPlasticet rubures, maResitives, anomisheni, maSalames kana insulting. Kunyanya, silica fume (etorphous silica) kana microsilica yakawedzerwa kuConcrete kuti uvandudze kusimba kongiri uye kusimba. Silica fume inoshandiswawo muFeatractor Concrete kuti ideredze porosity uye kusimudzira simba kuburikidza nekuvandudzwa kwezvinhu zvakarongedzwa.
Silica kupararira
Silica inowanikwa mune dzakasiyana siyana dze hydrophilic uye hydrophobic mafomu uye kazhinji inoshandiswa mune yakanaka kwazvo saizi. Kazhinji, Silika haaparadzira zvakanaka mushure mekunyorova. Inowedzerawo yakawanda madiki madiki emhepo mabhuruku kune iyo fomu yechigadzirwa.
Kune mazhinji Silika maficha, akanaka uye unifomu kupararira kwakakosha. Kunyanya kana ichishandiswa pakupenda uye mapopoma kuti uvandudze kupokana, iyo silica svina inoda kuve diki zvakakwana kuti isapindire nemwenje unooneka kuti udzivise hake uye chengetedza kujekesa. Kune mazhinji ejasi, silica inoda kuve isingasviki 40nm kuti isangane ichi chinodiwa. Kune zvimwe zvinoshandiswa, chigamba chinokwezva chinodzivirira mumwe nemumwe silica sida kubva mukudyidzana nenzvimbo yakatenderedza. Ultrasung yakaratidza kuve inoshanda zvakanyanya muSiltica kupararira kunoenzaniswa nedzimwe nzira dzakakwirira dzekusanganisa. PaAggregate saizi yakakura kupfuura mazana maviri emicons, mazhinji masisitimu akaderedzwa kusvika asingasviki 200 nanometers.
Ultrasonic kurapwa
Matatu eTIO2 PODERS aishandiswa mune iri basa: Naneparticle P25, NANOPArticle St21 uye Submicron Ht0514. P25 uye HT05414 yakagadzirirwa negesi yegasi synthesis; St21 yakagadzirwa nemakemikari emakemikari synthesis. Sodium Polyacrylates (PAA) ine huwandu hwemanyorerwe emanyorero e1200, 2100, 8000, zviuru zana nemakumi matatu nemakumi matatu zvakashandiswa sevanopararira polymeric. Kugadzirira kumiswa kwemvura, tio2 poda yakavhenganiswa nePAA mumvura. Gadzirisa phi ine AMMONA Solution (20%, ongororo yegiredhi). Zvekumira, makumi mashanu emamita kumiswa kwakasarudzwa mune 100 ml beaker kwemaminetsi makumi matatu. Kuti udzivise mvura kubhururuka uye panda gomba, kumiswa kwaive kurwiwa kagumi kagumi nemaminitsi matatu, sezvo mitatu yemaminitsi ekuenderera mberi kwakaguma nekuwedzera kwekuwedzera kwe60-70 ° C. Mushure memaminitsi matatu ezvimwe chete zvinoteedzana kurira, kumiswa kwacho kwakatonhorera kwemaminitsi gumi.
Isu taishandisa maviri seti yeiyo Ultrasonic Equipment, Frequency: 20 Khz; Amplitude: 30 - 34 mm; Chizvarwa Charudzi: 70 - 120 W; Tool musoro Dhivhiteri: 26 mm, mushure memaminitsi makumi matatu ekupedzisira kurapwa, mvura yakaderedzwa neinenge 10 nekuda kwekuvhura ml. Masemara akayerwa pamberi uye mushure mekumira, uye mvura yakachena yakawedzerwa kuti igadziriswe kurasikirwa. Pasinei neiyo vibration amplitude uye probe diameter, iyo viscosity uye average shuwa yemukuru weAgglomeiglomerated akaderera neiyo yerradiation nguva. Pakupedzisira mhinduro yacho inozotaridzwa uye iyo Sio2 particles dzinova diki zvakanyanya.
