Porous hlau daim nyias nyias feem ntau yog siv rau hauv kev khiav hauj lwm xws li kev sib cais, purification, thiab concentration. Vim nws cov yam ntxwv zoo heev, nws tau txais tos dav hauv kev lag luam ntau thiab ntau dua.
Dab tsi yog qhov zoo ntawm porous hlau membranes?
(1) Nws muaj kev ua haujlwm zoo, kev ua haujlwm vuam thiab kev sib khi ua haujlwm;
(2) Vim tias muaj zog txhua yam muaj zog, nws tuaj yeem siv rau hauv siab dua (sab siab txog li 31MPa), yog li cov txheej txheem ntawm kev ua kom lub siab sib txawv tuaj yeem siv los ua kom cov permeability thiab ua kom muaj peev xwm sib cais ntawm daim nyias nyias;
(3) Nws tuaj yeem tiv taus kev ua haujlwm kub ntawm 315 degree thiab muaj thermal conductivity zoo. Lub thermal stress nyob rau hauv lub membrane module yog me me, yog li qhov kub thiab txias yuav tsis cuam tshuam rau lub neej ntawm cov khoom siv membrane, thiab nws yuav ua rau kev ua haujlwm ruaj khov ntawm daim nyias nyias, thiab nws yuav ua rau tsis ua hauj lwm ntawm daim nyias nyias. ua kom puas;
(4) Nws tuaj yeem tiv taus cov kua qaub muaj zog thiab muaj zog alkali, tuaj yeem siv rau kev sib cais ntawm cov khoom siv pH huab cua, muaj kev hloov tau zoo rau cov ntaub ntawv, thiab nthuav dav daim ntawv thov ntawm cov tshuab sib cais membrane;
(5) Kev sib khi zoo, kev ua haujlwm zoo vuam, thiab kev sib txuas yooj yim ntawm cov khoom siv membrane;
(6) Kev ntxuav thiab tshuaj tua kab mob ntawm cov hlau ntxeem tau yooj yim. Cov hlau ntxeem tau tuaj yeem tiv taus kev ntxuav ntawm cov kua qaub thiab muaj zog alkali yam tsis ua rau cov khoom siv membrane puas, thiab cov khoom siv hlau ntxeem tau tuaj yeem ua kom tsis muaj menyuam ncaj qha los ntawm chav, thiaj li ua kom muaj kev nyab xeeb ntawm cov khoom siv. Cov kab mob ua haujlwm;
(7) Cov hlau ntxeem tau tuaj yeem siv rau kev sib cais ntawm cov khoom siv siab lossis cov kua dej siab siab, thiab cov pa phem me me heev;
(8) Lub neej kev pab cuam ntawm cov porous hlau membrane yog ntev;
(9) Nws muaj zog thov tus nqi. Thaum lub sij hawm filtration txheej txheem, cov porous hlau membrane muaj ib tug loj adsorption muaj peev xwm, kev txhawb nqa zoo, loj pom cheeb tsam, thiab tuaj yeem ntxuav hauv online yam tsis muaj kev cuam tshuam ntau lawm.
