Zeziphi izinto ezi-5 zereverse osmosis inwebu ongazaziyo?

01

Iselulosi acetate inwebu (CA inwebu sheet)

I-Cellulose acetate yi-particle emhlophe ekhululekile okanye i-powder fibrous, i-odorless, i-non-toxic, i-stable stable, kunye ne-hygroscopic ephezulu. Okwangoku sisixhobo esifundwa ngokubanzi esingasemva se-osmosis membrane. Nangona i-cellulose acetate iyinto enhle kwi-membrane, i-COOR kwikhonkco layo le-molecular yenza kube lula ukuba i-hydrolyze phantsi kobushushu obuphezulu kunye neemeko ze-acid-base, kunye ne-alkaline okanye i-acidic hydrolysis inokubangela ukuba iqela le-acetyl linyamalale. Ngoko ke, ukusetyenziswa kwezinto ezicocekileyo ze-CA kuxhomekeke kwimida ethile.

02

Ifilimu yepolyamide enuka kamnandi (iphepha le membrane yePA)

Iipolyamide ezinuka kamnandi zisetyenziswa kakhulu kwishishini lemembrane ngenxa yokuzinza komzimba kunye neekhemikhali, ukuchasana ne-alkalis eyomeleleyo, i-oyile esters, kunye nezinyibilikisi zezinto eziphilayo, kunye namandla afanelekileyo omatshini. Nangona kunjalo, ngenxa yendalo ehlawulisiweyo ye-PA membranes esebenza kwi-pH 6-10, amasuntswana emanzini athambekele ekufakeni phezu kwe-membrane, ukunciphisa ubomi benkonzo.

03

Chitosan inwebu (CS inwebu sheet)

I-Chitosan (CS) ifumaneka ngokususa amaqela e-acetyl kwiimolekyuli ze-chitosan. Inoluhlu olubanzi lwemithombo, iipropati ezilungileyo zokwenza ifilimu kunye ne-biocompatibility, kwaye kulula ukuyiguqula ngokwekhemikhali. Ngenxa yokwakheka kweemolekyuli, amanzi acocekileyo asetyenziswa kwi-osmosis ebuyela umva anokwenza iibhondi ze-hydrogen ezomeleleyo kunye neemolekyuli zamanzi, kwaye amandla awo okususa ii-ion zesinyithi zomhlaba zealkaline zomelele. Ngoko ke, iphezulu kwi-CA membranes kunye ne-polyamide membranes kwaye ithathwa njengento ethembisayo kakhulu ye-membrane, efumene ingqwalasela ebanzi kumazwe ngamazwe. I-Cs ibuyisela inwebu ye-osmosis inokuguquguquka okuphezulu kunye nokukhetha, kwaye inesiphumo esihle sokususa kwiityuwa zentsimbi edibeneyo. Ngenxa yokumelana ne-alkali eyomeleleyo kunye nokumelana ne-asidi emva kokudibanisa, iimbrane ze-Cs azikwazi lula ukuvelisa ii-microorganisms kwaye zihlala zisetyenziswa njenge-osmosis membranes ukuthambisa amanzi anzima.

04

Polyphenylene reverse osmosis inwebu

Izinto zePolyphenylene ezifana ne-polybenzimidazole (PBD) kunye ne-polyphenylene oxide (PPO) ziye zatsala ingqalelo ebanzi ngenxa yokumelana nobushushu obuphezulu, i-asidi kunye nokumelana ne-alkali, kwaye inokuguqulwa ukuze ifumane izinto ezingcono zefilimu ezibhityileyo.

05

Enye inwebu edibeneyo ye-osmosis edibeneyo

I-composite reverse osmosis inwebu luhlobo lwe-membrane edibanisa i-membrane ebhityileyo, exineneyo yezixhobo ezahlukeneyo kunye nemisebenzi ekhethekileyo yokwahlula kwi-substrate yenkxaso ye-porous. Inezinga eliphezulu lokwahlulwa kwe-solute kunye nesantya sokungena kwamanzi kune-membrane ezidibeneyo, kwaye ngenxa yoko inesabelo semarike esingaphezulu kwe-90%. Okwangoku, i-membrane edibeneyo ye-osmosis edibeneyo isetyenziswe ngokubanzi kwimimandla efana ne-petrochemicals, i-electronics, impahla, imboni yokukhanya, isinyithi, amayeza, i-biotechnology, ukutya kunye nokukhuselwa kwendalo.
