Umgomo wokusebenza we-Diatomite Filter Aid
Umsebenzi wezinsiza zokuhlunga uwukushintsha isimo sokuhlanganisa sezinhlayiya, ngaleyo ndlela kuguqule usayizi wokusabalalisa izinhlayiya ku-filtrate. Isihlungi se-Diatomite Aidare ikakhulukazi esakhiwe i-SiO2 ezinzile kumakhemikhali, enama-micropores amaningi angaphakathi, akha izinhlaka eziqinile ezihlukahlukene. Ngesikhathi senqubo yokuhlunga, umhlaba we-diatomaceous uqala ukwakha isihlungi esinezimbotshana zosizo (ukumbozwa kwangaphambili) epuleti lokuhlunga. Lapho i-filtrate idlula kusizo lwesihlungi, izinhlayiya eziqinile ekumisweni zakha isimo esihlanganisiwe, futhi usayizi wokusabalalisa uyashintsha. Ukungcola kwezinhlayiya ezinkulu kuyabanjwa futhi kugcinwe ebusweni bendawo, okwenza isendlalelo sokusabalalisa usayizi omncane. Baqhubeka bevimbela futhi babambe izinhlayiya ezinobukhulu obufanayo, kancane kancane benza ikhekhe lokuhlunga ngama-pores athile. Njengoba ukuhlunga kuqhubeka, ukungcola okunosayizi wezinhlayiyana ezincane kancane kancane kungena endaweni enezimbotshana yosizo lwesihlungi somhlaba we-diatomaceous futhi kuyabanjwa. Ngenxa yokuthi umhlaba we-diatomaceous une-porosity engaba ngu-90% kanye nendawo enkulu yendawo ethile, lapho izinhlayiya ezincane nama-bacterium zingena ezimbotsheni zangaphakathi nangaphandle zosizo lokuhlunga, zivame ukunqanyulwa ngenxa ye-adsorption nezinye izizathu, ezinganciphisa i-0.1 μ The ukususwa kwezinhlayiya ezinhle namabhaktheriya kusuka ku-m kuzuze umphumela omuhle wokuhlunga. Umthamo wosizo lwesihlungi ngokuvamile u-1-10% wesisindo esiqinile esithintekile. Uma umthamo uphezulu kakhulu, empeleni uzothinta ukuthuthukiswa kwesivinini sokuhlunga.
Umphumela wokuhlunga
Umphumela wokuhlunga we-Diatomite Filter Aid utholakala ikakhulukazi ngalezi zenzo ezintathu ezilandelayo:
1. Umphumela wokuhlola
Lona umphumela wokuhlunga okungaphezulu, lapho uketshezi lugeleza emhlabeni we-diatomaceous, ama-pores omhlaba we-diatomaceous mancane kunosayizi wezinhlayiyana zezinhlayiya ezingcolile, ngakho-ke izinhlayiya zokungcola azikwazi ukudlula futhi ziyanqanyulwa. Lo mphumela ubizwa ngokuthi ukusefa. Eqinisweni, ingaphezulu lekhekhe lokuhlunga lingabhekwa njengendawo yesisefo enosayizi olinganayo wembotshana ophakathi. Uma ububanzi bezinhlayiya eziqinile bungekho ngaphansi (noma ngaphansi kancane) kobubanzi bembotshana yomhlaba we-diatomaceous, izinhlayiya eziqinile "zizohlungwa" ngaphandle kokumiswa, zidlale indima ekuhlungeni okungaphezulu.
2. Umphumela ojulile
Umthelela wokujula wumphumela wokugcina wokuhlunga okujulile. Ekuhlungeni okujulile, inqubo yokuhlukanisa yenzeka kuphela phakathi nendawo. Ezinye zezinhlayiya ezincane zokungcola ezidlula ebusweni bekhekhe lokuhlunga zivinjwa iziteshi ezincane ezimazombezombe ngaphakathi komhlaba we-diatomaceous kanye nezimbotshana ezincane ngaphakathi kwekhekhe lokuhlunga. Lezi zinhlayiya zivame ukuba zincane kunama-micropores emhlabeni we-diatomaceous. Lapho izinhlayiya zingqubuzana nodonga lwesiteshi, kungenzeka ukuhlukana nokugeleza kwamanzi. Kodwa-ke, ukuthi bangakwazi yini ukufeza lokhu kuncike ebhalansi phakathi kwamandla angenayo kanye nokumelana kwezinhlayiya. Lesi senzo sokunqamula kanye nokuhlola kuyafana ngokwemvelo futhi kungokwesenzo somshini. Ikhono lokuhlunga izinhlayiya eziqinile ngokuyisisekelo lihlobene kuphela nosayizi ohlobene nokuma kwezinhlayiya eziqinile nezimbotshana.
3. Umphumela we-Adsorption
Umphumela we-adsorption uhluke ngokuphelele ezindleleni ezimbili zokuhlunga ezishiwo ngenhla, futhi lo mphumela ungabonakala njengokukhanga kwe-electrokinetic, okuncike kakhulu endaweni engaphezulu yezinhlayiya eziqinile kanye nomhlaba we-diatomaceous ngokwawo. Lapho izinhlayiya ezinezimbotshana ezincane zangaphakathi zishayisana nobuso bomhlaba we-diatomaceous onezimbotshana, zikhangwa amashaji aphikisanayo noma zakha amaqoqo amaketango ngokudonselana phakathi kwezinhlayiya futhi zinamathela kumhlaba obizwa ngokuthi i-diatomaceous, wonke oyingxenye ye-adsorption. Umphumela we-adsorption uyinkimbinkimbi kakhulu kunawokuqala amabili, futhi ngokuvamile kunenkolelo yokuthi isizathu esenza ukuba izinhlayiya eziqinile ezinobubanzi bembobo emincane zinqanyulwe sibangelwa ikakhulukazi:
(1) Amandla e-Intermolecular (owaziwa nangokuthi i-van der Waals attraction), okuhlanganisa ukusebenzisana kwe-dipole unomphela, ukusebenzisana kwe-dipole okukhangisiwe, nokusebenzisana kwe-dipole okusheshayo;
(2) Ukuba khona kwamandla kaZeta;
(3) Inqubo yokushintshanisa i-ion.
