I-Silica isetyenziswa kumashishini ahlukeneyo ukuze anciphise ukunyangwa, ukufakelwa kombane kunye nozinzo oluphakamileyo. Ukusasazeka kwe-ultrasonic ukusasazeka kuyanceda ukuvula amandla e-silica ngokuphucula umgangatho wokusasazeka.
Isicelo se-silica
I-Silica (i-SIO2) i-cemaral ye-ceramic ye-ceramic esetyenziswe kwimizi-mveliso eyahlukeneyo ukuphucula iipropathi zomhlaba kunye noomatshini bezinto ezahlukeneyo. Isetyenziswa njenge-fililler, i-songer yentsebenzo, i-Rheoology Sheeifier okanye i-SUSTER kwifomu yemveliso emininzi enjengeepeyinti kunye neepali, iibhulukhwe, iibhulukhethisi, izityholo, ibhulukhethisi, ibhulukuthelo, i-chicletic okanye i-therhesings, ireyithingi. Ngokukodwa, i-Silica fume (i-amorphouslica) okanye i-microsila yongezwa kwikhonkrithi yokuphucula amandla ekhonkrithi kunye nokuqina. I-Silica ifume isetyenziswa kwikhonkrithi ye-Recractory yokunciphisa ukunciphisa ukukhulisa amandla kunye nokuphucula amandla ngokupakisha i-paricle ipakisha.
Ukusasazeka kwe-Silica
I-Silica ifumaneka kwiifom ezahlukeneyo ze-hydrophobic kwaye isetyenziswa ngokuqhelekileyo kwindawo entle kakhulu. Ngokwesiqhelo, i-silica ingasasazeki kakuhle emva kokumanzisa. Ikwakongeza amaqamza amaninzi amancinci kwifomula yemveliso.
Kwizicelo ezininzi ze-silica, ukusasazeka kunye nokungafaniyo kwaye ibalulekile. Ingakumbi xa isetyenziswa kwi-paints nakwi-lacquers ukuphucula ukumelana nokukrakra, amasuntswana esilica kufuneka abe mncinci ngokwaneleyo ukuba angaphazamisi ukukhanya okubonakalayo ukuphepha ukucaciswa kunye nokulungiswa. Ngeengubo ezininzi, i-silica kufuneka ibe ngaphantsi kwe-40NM ukuze ifezekise le mfuno. Kwezinye izicelo, ukuphazamiseka kwesuntsule kuthintela umntu ngamnye kwi-slicar nganye kwi-sublecle isebenzisana nephakathi. Unyango luye lwangqinisisa ukuze lusebenze ngakumbi ekusasazeni i-silicarations ngokuthelekiswa nezinye iindlela eziphezulu zokuxuba. Kwi-Aggregate Sagera ngaphezulu kwe-200 microns, uninzi lwamasuntswana lwancitshiswa laba ngaphantsi kwama-200 nanometers.
Unyango lwe-Ultrasonic
Iipowuni ezintathu ze-tio2 zasetyenziswa kulo msebenzi: i-nanoparcle p25, i-nanoparcale iSt21 kunye ne-Subarmil ht0514. I-P25 ne-HT0514 ilungiselelwe yiSigaba seS synthesis; I-ST21 yadaniswa yi-synthesi yemichiza emanzi. I-Sodium Polysacrylatetes (i-PAA) ngo-1200, 2100, 8000, i-15000 nengama-30000 kwaye isetyenziswa njengabasasazi be-polymeric. Ukulungiselela ukumiswa okukhulu, i-tio2 powder yayixutywe nePAA emanzini. Lungisa i-PH kunye nesisombululo se-ammonia (i-20%, iBanga lokuhlalutya). Ukuze uhlonityhefu, i-50 ml yokumiswa kwakwi-100 ml beaker kangangemizuzu engama-30. Ukuthintela amanzi abilayo kunye ne-paa grading, ukumiswa kungeniswa izihlandlo ezi-10 ngemizuzu emi-3 nganye, ukusukela i-Irradition eqhubekayo kuphumela ekubeni i-60-70 ° C. Emva kwemizuzu emi-3 ye-Irradication nganye, ukumiswa kuphononongwe imizuzu eli-10.
Sasebenzisa iiseti ezimbini zezixhobo ze-Ultrasonic, rhoqo: 20 KHZ; I-Ampling: 30 - 34 mm; Isizukulwana samandla: 70 - 120 w; Isixhobo sentloko Ubunzima balinganiswa ngaphambi nasemva kokuzalwa, kwaye amanzi acocekileyo avuswa ukuba ahlawule ilahleko. Nokuba yeyiphi na i-americation kunye ne-probe ye-probemes, ubungakanani be-viscosity kunye nobungakanani be-avericle ye-avelmumentraments enqunyanyisiweyo inciphile ixesha lokuhlutha ixesha elinomsindo. Ekugqibeleni isisombululo siyabonakala ngokucacileyo kwaye amasuntswana eSiolo2 abona incinci kakhulu.
