Silica ikoreshwa mu nganda zitandukanye zo kwambara, kugira ngo amashanyarazi no gushikama cyane. Gutandukanya Ultrasonic bifasha gufungura ubushobozi bwa silica mugutezimbere ubuziranenge.
Gusaba Silica
Silica (Sio2) ni ibikoresho byo mu mikino myinshi ikoreshwa mu nganda zitandukanye kugira ngo hejuru n'ubutaka bwibikoresho bitandukanye. Ikoreshwa nkuzuzanya, imikorere yongeraho, uburyo bwo gutunganya cyangwa gutunganya infashanyo mubicuruzwa byinshi nkamashusho nibikorwa bya plastike, ibihuha, imyambaro, imyambaro, imyambaro, imyambaro. By'umwihariko, umwotsi wa silica (amorfous silica) cyangwa microsilica yongewe kuri beto kugirango atezimbere imbaraga zifatika. Silica fume nayo ikoreshwa mu buryo bworoshye bwo kunozwa kugirango igabanye uburozi kandi izamure imbaraga binyuze mu gupakira.
Silica yatanaga
Silica iraboneka muburyo butandukanye bwa hydrophilic hamwe nuburyo bwa hydrophobike kandi mubisanzwe ikoreshwa mubunini bwiza cyane. Mubisanzwe, Silica ntabwo ikwirakwiza nyuma yo gutongana. Irimo kandi intoki nyinshi zo mu kirere kuri formula.
Kuri porogaramu nyinshi za Silica, gutatanya neza kandi kimwe ni ngombwa. Cyane cyane iyo ukoreshwa mu gushushanya na lacquers kugirango bateze imbere kurwanya, ibice bya silica bigomba kuba bito bihagije bitabangamira urumuri rugaragara kugirango wirinde igihome kandi ugakomeza gusobanuka. Kubintu byinshi, Silica igomba kuba munsi ya 40nm kugirango yuzuze iki gisabwa. Kubindi bikorwa, agglomeration ya agglomera irinda buri gice cya silica kugiti cye cyo gusabana nuburyo buzengurutse. Ultrasonsationdos yagaragaye ko ikora neza muri Silica yatananye nubundi buryo bwo kuvanga imivugo. Muri rusange ingagi zirenga mikene 200, ibice byinshi byagabanutse kugera kuri saa sita za Nanometero 200.
Kuvura ultrasonic
Abakinnyi batatu ba Tio2 bakoreshejwe muri uyu murimo: Nanoparticle P25, Nanoparticle ST21 na Submicron Ht0514. P25 na HT0514 byateguwe na synthesi yicyiciro cya gaze; ST21 yahimbwe na synthesique synthesis. Sodium polyacrylates (paa) hamwe nuburemere bwa molekile ya 1200, 2100, 8000, 15000 na 30.000 byakoreshejwe nk'abanyageragezo ba Polonye. Gutegura ihagarikwa ry'amazi, ifu ya Tio2 yavanze na paa mumazi. Hindura PH hamwe nigisubizo cya ampina (20%, icyiciro cyo gusesengura). Kubwa Syanicali, ML 50 yo guhagarikwa yarimbuwe muri ML 100 iminota 30. Kugira ngo amazi atere kandi Paa Gelling, hakuweho inshuro 10 man buri umwe, kubera ko 3 min yo guhora imaze kuva mu bushyuhe bwa 60-70 ° C. Nyuma yiminota 3 ya buri muyoboro wakurikiranye, guhagarikwa byakonje muminota 10.
Twakoresheje ibice bibiri byibikoresho bya ultrasonic, inshuro: 20 khz; Amplitude: 30 - 34 mm; Igisekuru cy'amashanyarazi: 70 - 120 W; Diamery Umutwe Diameter: 26 mm, nyuma yiminota 30 yo kuvura ultrasonic, amazi yagabanutseho hafi 10 kubera gutandukana ml. Uburemere bwapimwe mbere na nyuma yo gusana, n'amazi meza yongewemo kugira ngo yishyure igihombo. Utitaye ku kunyeganyega no gufata umwanzuro, virusi n'imbonerahamwe n'ubunini bw'ibiciro bya Agglomeratestes zahagaritswe byagabanutseho igihe cyo kurakara. Amaherezo, igisubizo gihinduka umucyo kandi ibice bya sio2 biraba bito cyane.
