Flocculing
Mumunda weChemistry, floculation ndiyo nzira iyo collodal compoles inobuda kubva kune yakanakira muFlecucleent kana Flake Fomu kubva kumisikidzwa kana nekuwedzera kweClarfier. Maitiro aya anosiyana neyekupunzika mune iyo colloid inongomiswa mumvura sekupararira kwakagadzikana isati yafa uye haina kunyatso nyarara mumhinduro.
Cogulation uye fluculation yakakosha maitiro emvura pakurapwa kwemvura. Chiitiko cheCogation ndeyekuita kuti ubudirire uye kuunganidza zvimiti zvekudyidzana pakati pekubatana uye colloid, uye flycirtulate uye inodakadza zvimedu zvisina kufanira nekuvanza.
Tsanangudzo yenguva
Sekureva kwa IUPAC, fluclation ndeye "maitiro ekutaurirana uye kuungana nepo zvivakwa zvechikamu chevhu zvakakura zvehukuru hwakakura".
Chaizvoizvo, fluclating ndiyo nzira yekuwedzera iyo floculant yekuparadzira yakagadziriswa midziyo yakabhadharwa. Panguva imwecheteyo, fluclating hunyanzvi hwekusanganisa hunosimudzira hukuru hwekuwedzera uye hunobatsira kugadzirisa. Coagulanti yakajairika ndeye al2 (saka4) 3 • 14hka.
Chikumbiro munda
Kurapa Kwemvura Tekinoroji
Flocculation uye precipitation inoshandiswa zvakanyanya mukunatswa kwemvura yekunwa uye mukurapa kwegungwa, dutu uye maindasitiri marara. Maitiro ekurapa ekurapa anosanganisira gratings, coaglation, fliveculation, yakatsvaira, kusvitsa mutserendende uye nekuwarira.
Survents Chemistry
Mucolidal chemistry, fluclation ndiyo maitiro ayo anodzvanywa zvidimbu zvakasungwa pamwechete. Iyo floc inogona kuyirira kumusoro kwemvura (opalescent), gadzirisa kusvika kuzasi kwemvura (likepitate) kana nyore firita kunze kwemvura. Maitiro ekurima esaidhi akanyatsoenderana nemhando yepamusoro yemhando yepamusoro. Kupararira kukuru kwevhu revhu hakuna kungoita kuti tirwarise yemvura yakatenderedza, asi zvakare inokonzera zvakare etrophiction nekuda kwekutora kwevakadzi mu nzizi, nyanza uye kunyange submarine hull.
Chemistry yemuviri
Kuti uwane emultions, floculation inotsanangura kusunganidzwa kwemakonzo akaparadzaniswa emadhonzo kuti arege kurasikirwa nezvivakwa zvavo. Nekudaro, flitulation ndiyo yekutanga nhanho (collet collet coallescence uye yekupedzisira chikamu kupatsanurana) iyo inotungamira mukuwedzera kuchembera kwe emulsion. Vanofamba vanoshandiswa vanoshandiswa mumaminerari vanowana mukana, asi vanogona zvakare kushandiswa mukugadzirwa kwezvinhu zvemuviri zvezvikafu nezvinodhaka.
Defloclate
Reverse filculing ndiyo chaiyo yakatarisana nekufa uye dzimwe nguva inonzi gelling. Sodium silte (na2sio3) muenzaniso chaiwo. Zvikamu zveCollodal zvinowanzo kuparadzirwa pamusoro ph zvakakwira pH. Kunze kweiyo yakaderera ionic simba reiyo mhinduro uye kutonga kwezvinhu monovalent esimbi. Kuzvidhira zvinodzivirira kuti colloid kubva pakugadzira flucculent anonzi antiffloculants. Kuti udzoreredze kuraswa kuburikidza nemagetsi ekudzivirira kwemagetsi, mhedzisiro yekudzosera kumashure inogona kuyerwa ne zeta kugona. Maererano neiyo Encyclopedia duramazwi rePolymers, antiffloculation "mamiriro kana mamiriro ekupararira mune imwe mvura yakasimba inosara yakazvimirira uye isina kujairika kune vavakidzani vayo (yakawanda kunge emulsifier). Isina-yekubhururuka inotsemuka ine zero kana yakaderera goho rezvibereko ".
