PTFE Membrane Filters Details

PTFE lera filthara na le e babatsehang ea lik'hemik'hale sebeletsana, e le hore ba boetse ba sebelisoa bakeng sa filtration ea solvents le asiti, eo filtara tse ling ha ba hanyetsane.Ka lebaka la litšoaneleho tsa bona tsa hydrophobic, li tlameha ho tšeloa ka ethanol kapa methanol pele ho hloekisoa ha mecha ea litaba ea metsi.

Li-filters tsa "membrane" kapa "li-membrane" ke lifilimi tsa polasetiki tse nyenyane tse nang le litekanyetso tse khethehileng tsa boholo ba pore.E boetse e tsejoa e le skrine, sefe kapa sefe se senyenyane, 'me membrane e boloka likaroloana kapa likokoana-hloko tse kholo ho feta boholo ba pore haholo-holo ka ho tšoara bokaholimo.Likaroloana tse ling tse nyane ho feta boholo ba pore e boletsoeng li ka bolokoa ke mekhoa e meng.Li-membrane tsa PTFE li hlahisoa ke lits'ebetso tse tharo tse fapaneng.Li-Mixed Cellulose Esters, Cellulose Acetate, le Nylon ke li-membrane tsa reverse phase solvent, moo mouoane o laoloang kapa ho tlosoa ha mokhoa o rarahaneng oa solvent ho theha sebopeho sa porous.Ka bobeli hydrophilic le hydrophobic PTFE li entsoe ka mokhoa o nang le tokelo ea molao moo li-membrane li otlolloang ka biaxially ho theha sebopeho sa porous.

Litšobotsi tsa Ts'ebetso ea PTFE Membranes

• E matla: Li-membrane tsa PTFE li hlokomeloa bakeng sa ho phatloha (longitudinal) le tensile (lateral) matla.Supported Acetate le Nylon ke li-membrane tse matla ka ho fetisisa tse ka morao tse fumanehang.
• E hloekile ka lik'hemik'hale le tsa baeloji: E le karolo ea lenaneo le akaretsang la boleng, ke li-reagents tse phahameng tsa bohloeki le lisebelisoa tse tala feela tse sebelisetsoang ho hlahisa li-membrane tsa PTFE. Hang ha li se li entsoe, li-membrane li tšoaroa ka kamoreng e hloekileng ea sehlopha sa 1000 ho fokotsa tšilafalo ea tikoloho.Le hoja li-membrane tse ling li hloka tekanyo e nyenyane (0.1-3 boima %) ea motsoako oa metsi a nang le metsi, Cellulose acetate e na le lisebelisoa tse tlaase ka ho fetisisa tse nang le metsi (0.1 boima %) le Nylon, ka tlhaho ea hydrophilic, ha e na lisebelisoa tse ekelitsoeng tsa metsi kapa li-surfactants.
• Li-membrane tse tšesaane tse nang le porosity e phahameng: Li-membrane tse tšesaane tse sa tšoaneng (hangata 150 µm) tse nang le porosity e phahameng (hoo e ka bang 80%) li fana ka khase e phahameng le phallo ea metsi sebakeng se seng le se seng.Porosity e phahameng e boetse e fana ka sebaka se phahameng sa holimo bakeng sa adsorption kapa ho tlama.
• Thermostable: Li-membrane tsohle tsa PTFE li ka etsoa sterilized ka autoclaving.Mocheso o sebetsang oa ho fihla ho 180 ° C o ka finyelloa ho itšetlehile ka lera la polymer .PTFE li-membrane li bonts'a ho fokotseha ho fokolang ha mocheso o phahameng.

Tataiso e Potlakileng ea ho Khetha Lisefe tsa Membrane

• Etsa qeto ea hore na ke mokelikeli kapa khase efe e tla sefuoa.
• Hlahloba hore na ke li-membrane life tse lumellanang le lik'hemik'hale.
• Etsa qeto ea boholo ba pore e hlokahalang ho finyella liphello tseo u li batlang.
• Sheba lintlha tsa lera bakeng sa maemo afe kapa afe a sa tloaelehang a ka 'nang a fokotsa khetho ea hau ea lera (mohlala, mocheso).
