Umgaqo osebenzayo weDiatomite Filter Aid
Umsebenzi wezixhobo zokucoca kukutshintsha imeko yokuhlanganiswa kwamasuntswana, ngokwenjenjalo ukuguqula ubungakanani bosasazo lwamasuntswana kwifiltrate. I-Diatomite Filter Aidare iqulunqwe kakhulu yi-SiO2 yekhemikhali ezinzileyo, enemikropore eninzi yangaphakathi, eyenza izakhelo ezahlukeneyo ezinzima. Ngexesha lenkqubo yokuhluza, umhlaba we-diatomaceous kuqala wenze i-porous filter aid medium (precoating) kwipleyiti yokucoca. Xa i-filtrate idlula kwi-filter aid, i-particle eqinile kwi-suspension yenza i-state aggregated, kunye noshintsho lokusabalalisa ubungakanani. Ukungcola kwamaqhekeza amakhulu kubanjwe kwaye kugcinwe phezu kwendawo ephakathi, okwenza ubungakanani obuncinci bokusabalalisa. Baqhubeka bethintela kwaye babambe iinqununu ezinobungakanani obufanayo, ngokuthe ngcembe benza ikhekhe lokucoca kunye neepores ezithile. Njengoko ukuhluzwa kuqhubela phambili, ukungcola okunamasuntswana amancinci angena kancinci kancinci kwi-porous diatomaceous earth filter aid medium kwaye ayabanjwa. Ngenxa yokuba umhlaba we-diatomaceous une-porosity malunga ne-90% kunye nommandla omkhulu wendawo ethile, xa iincinci ezincinci kunye neebhaktheriya zingena kwi-pores yangaphakathi nangaphandle ye-filter aid, zihlala zithintelwa ngenxa ye-adsorption kunye nezinye izizathu, ezinokunciphisa i-0.1 μ The ukususwa kweengqungquthela ezintle kunye neebhaktheriya ezivela kwi-m zifezekise umphumo omuhle wokucoca. Idosi yoncedo lokucoca luqhele ukuba yi-1-10% yobunzima obuqinileyo obanjiweyo. Ukuba idosi iphezulu kakhulu, iya kuchaphazela ukuphuculwa kwesantya sokuhluza.
Isiphumo sokuhluza
Isiphumo sokuhluzwa kweDiatomite Filter Aid sifumaneka ikakhulu ngezi zenzo zintathu zilandelayo:
1. Uvavanyo lwesiphumo
Lo ngumphumo wokucoca umphezulu, apho xa i-fluid idlula emhlabeni we-diatomaceous, ii-pores zomhlaba we-diatomaceous zincinci kune-particle ye-particle ye-particle yokungcola, ngoko ke iinqununu zokungcola azikwazi ukudlula kwaye zithintelwe. Esi siphumo sibizwa ngokuba sieving. Ngapha koko, umphezulu wekhekhe lokucoca unokubonwa njengendawo yokuhluza kunye nobungakanani obulinganayo bepore. Xa i-diameter yamasuntswana aqinileyo ingekho ngaphantsi (okanye ngaphantsi kancinane) kwedayamitha yepore yomhlaba wediatomaceous, amasuntswana aqinileyo aya "kukhuselwa" ngaphandle kokunqunyanyiswa, adlale indima kuhluzo lomphezulu.
2. Isiphumo esinzulu
Isiphumo sobunzulu sisiphumo sokugcinwa kokucoca okunzulu. Kwi-filtration enzulu, inkqubo yokwahlula kwenzeka kuphela ngaphakathi kwendawo ephakathi. Amanye amasuntswana okungcola amancinci adlula kumphezulu wekeyiki yokucoca athintelwe yimijelo emincinci ejikelezayo ngaphakathi kumhlaba wediatomaceous kunye neepores ezincinci ngaphakathi kwekeyiki yokucoca. La masuntswana adla ngokuba mancinci kunemicropores kumhlaba wediatomaceous. Xa iinqununu zingqubuzana nodonga lomjelo, kunokwenzeka ukukhupha ukusuka kwi-liquid flow. Nangona kunjalo, nokuba banokufezekisa oku kuxhomekeke kwibhalansi phakathi kwamandla angenayo kunye nokuchasana kwamasuntswana. Oku kunqanda kunye nesenzo sokuhlola kuyafana kwindalo kwaye yeyesenzo soomatshini. Ukukwazi ukuhluza amasuntswana aqinileyo ngokusisiseko kunxulumene kuphela nobungakanani obunxulumene kunye nokumila kwamasuntswana aqinileyo kunye neepores.
3. Impembelelo ye-Adsorption
Impembelelo ye-adsorption yahluke ngokupheleleyo kwiindlela ezimbini zokuhluza ezikhankanywe ngasentla, kwaye esi siphumo sinokubonwa njengomtsalane we-electrokinetic, oxhomekeke ubukhulu becala kwiipropati zomphezulu wamasuntswana aqinileyo kunye nomhlaba we-diatomaceous ngokwawo. Xa amasuntswana anemingxuma emincinci yangaphakathi engqubana nomphezulu we-diatomaceous earth, atsalwa ziintlawulo ezichaseneyo okanye enze amaqoqo amakhonkco ngokutsalelana phakathi kwamasuntswana kwaye abambelele kumhlaba wediatomaceous, zonke ezo ze-adsorption. Impembelelo ye-adsorption intsonkothe ngakumbi kunezimbini zokuqala, kwaye kukholelwa ngokubanzi ukuba isizathu sokuba amasuntswana aqinileyo anedayamitha emincinci yepore athintelwe ikakhulu ngenxa yoku:
(1) Amandla e-Intermolecular (ekwabizwa ngokuba yi-van der Waals attraction), kubandakanywa ukusebenzisana kwe-dipole esisigxina, ukusebenzisana kwe-dipole, kunye nokusebenzisana kwe-dipole ngokukhawuleza;
(2) Ubukho beZeta ezinokubakho;
(3) Inkqubo yokutshintsha i-ion.
