Dizilo dongosolo kusefera chithunzi
Dizilo fyuluta zikuchokera
Sefa dizilo makamaka imakhala mpope dzanja mafuta (mpando fyuluta), chigawo chimodzi fyuluta, ndi kachipangizo madzi, ndi kachipangizo kutentha, ndi chotenthetsera, ndi kusindikiza mphete, payipi limodzi ndi monga, mmene membala fyuluta pachimake ndi zosefera amafotokozera, kuwona zojambula structural.
Sefani kuyeretsa njira ndi mfundo ntchito
(1) Kuyezetsa magazi zotsatira
Pamene madzimadzi umadutsa thupi porous, particles chodetsa cha kukula tinthu mu madzimadzi ndi intercepted ndi thupi porous padziko; particles ndi awiri particles ang'onoang'ono kuposa thupi porous kudutsa thupi porous ndi madzimadzi.
The mosamala zotsatira ndi mfundo za sefa. Mkuluyu sefa fyuluta ndi pamwamba fyuluta ndi osasankhidwa malinga ndi mmene mosamala. Popeza pore awiri a sefa sing'anga ndi awiri particles wodetsedwa si wozungulira, ali ofanana pore diameters ndi lofanana tinthu diameters. Choncho, tinthu kukula ikumalanda n'chochepa kwambiri kuposa pore kukula kwa nkhani fyuluta.
(2) Brownian zoyenda
Chodabwitsa kuti particles inaimitsidwa mosalekeza kusuntha zoumbika mosiyanasiyana amatchedwa Brownian zoyenda) ndi loitanirana wa particles ndi particles zonyansa madzimadzi kutsatira kupanga osasamba Brownian zoyenda nthawi zonse, ndipo Pamilunguyo ndipo anapitiriza pamene kusamukira ku pore mpanda wa porous thupi. Mu malo aang'ono pa khoma la dzenje, izo osasankhidwa kunja ndi thupi porous.
Wodetsedwa particles amathanso adzawombana ndi mzake chifukwa zoyenda Brownian ndi kugwedera madzi, ndi m'mimba mwake mwina particles pang'onopang'ono kumawonjezera pansi padziko kulumikiza mphamvu. Izo ziri zodziwika bwino kuti pamwamba mphamvu ukuwonjezeka ndi tinthu ngati amachepetsa tinthu kukula (osiyanitsidwa ubale) ndi njila kwa muzu lalikulu m'dera kukhudzana pakati pa particles, kuti miniti particles mosavuta aggregated ndipo si mosavuta omwazika.
(3) Kugaŵanitsidwa "kuyandikana" ndi "Mtunda" zotsatira za media (monga mafuta ndi madzi) ntchito fyuluta media
Pamene otaya mafuta ndi m'malovu ting'onoting'ono madzi akulowa ngati " ovomereza mafuta " mafuta " ochepa " madzi fyuluta chuma (monga microporous fyuluta pepala ndi okhutira utomoni 27. ~ 32%), chifukwa " kuyandikana " nkhani fyuluta mafuta The otaya mafuta bwino umadutsa ndi micropores nkhani fyuluta; chifukwa cha "patali" wa sefa chuma madzi, tating'ono madzi m'malovu sangathe bwino kudutsa micropores nkhani fyuluta. Chifukwa zotsatira wetting m'malovu madzi kakang'ono pa fyuluta pepala kufwanyulira, tating'ono madzi m'malovu asungidwa pa kufwanyulira wa fyuluta pepala. Ting'onoting'ono ta madzi m'malovu amene intercepted pang'onopang'ono kuonjezera, kuwachititsa pang'onopang'ono coalesce mu m'malovu lalikulu madzi. Mu zochita za kuthamanga mafuta m'malovu madzi mwamtundu ndi ndime mphero zooneka amafotokozera kutseka kupanga zikuluzikulu m'malovu madzi. Mu zochita za kuthamanga mafuta, pambuyo madzi m'malovu kudutsa zinthu fyuluta, iwo chokhazikika ndi kugwera mu chikho madzi yosonkhanitsa pansi zochita za misa zawo.
Ambiri ntchito limodzi ndi kupatutsa madzi kuchokera mafuta. The bwino "ochepa" ntchito za chuma fyuluta bwino zotsatira za kulekanitsa madzi.
