PTFE Membrane Filters Details

PTFE membrane sefa ine yakanakisa kemikari inoenderana, kuitira kuti ishandiswe zvakare kusefa yezvinonyungudutsa uye acids, kune mamwe mafirita asingadzivirirwe.Nekuda kwehunhu hwavo hwehydrophobic, vanofanirwa kunge vakanyoroveswa ne ethanol kana methanol isati yasefa yeaqueous media.

Nhanganyaya

Masefa eMembrane kana "membranes" mafirimu epurasitiki ane microporous ane chiyero chekukura kwepore.Iyo inozivikanwawo sescreen, sieve kana microporous filters, membranes inochengeta twudiki kana tupukanana tuhombe kupfuura saizi yepore yavo kunyanya nekubata pamusoro.Mamwe madiki pane akarehwa saizi yepore anogona kuchengetwa nedzimwe nzira.PTFE membranes inogadzirwa nemaitiro matatu akasiyana.Yakasanganiswa Cellulose Esters, Cellulose Acetate, uye Nylon are reverse phase solvent cast membranes, uko kunodzorwa kubuda kana kubviswa kweiyo yakaoma solvent system inoumba iyo porous chimiro.Ose ari maviri hydrophilic uye hydrophobic PTFE anogadzirwa ne patented process apo membrane dzakatambanudzwa biaxially kuti dzigadzire porous chimiro.

Kuita Hunhu hwePTFE Membranes

• Strong: PTFE membranes inotariswa kune zvose kuputika (longitudinal) uye tensile (lateral) simba.Inotsigirwa Acetate uye Nylon ndiyo yakasimba yereverse phase membranes iripo.
• Kemikari uye biologically yakachena: Sechikamu chepurogiramu yehutano hwakazara, chete high purity reagents uye zvinhu zvakasvibirira zvinoshandiswa kugadzira PTFE membranes.Kana yakandwa, iyo membrane inobatwa mukirasi 1000 yakachena kamuri kuti kuderedza kusvibiswa kwepakati.Nepo mamwe ma membranes achida huremu hudiki (0.1-3 huremu %) hweaqueous wetting agent, Cellulose acetate ine yakaderera aqueous extractables (0.1 huremu %) uye Nylon, inherently hydrophilic, haina akawedzera wetting agents kana surfactants.
• Nhete dzakatetepa dzine high porosity: Membrane yakaonda yakafanana (kazhinji 150 µm) ine yakakwira porosity (inenge 80%) inopa yakakwira gasi uye kuyerera kwemvura panzvimbo yeyuniti.High porosity inopawo nzvimbo yakakwirira yepamusoro yeadsorption kana kusunga.
• Thermostable: Ese PTFE membranes anogona sterilized ne autoclaving.Kushanda tembiricha inosvika 180°C inogona kuwanikwa zvichienderana ne membrane polymer .PTFE membranes anoratidza kushoma shrinkage panguva yakakwirira tembiricha.

Kurumidza Nhungamiro Yekusarudza Membrane Mafirita

• Sarudza kuti ndechipi mvura kana gasi richasefa.
• Tarisa kuti ndedzipi membranes dzinoenderana nemakemikari.
• Sarudza iyo yakakura pore saizi inodiwa kuti uwane mhedzisiro yaunoda.
• Tarisa zvimisikidzo zvemembrane kune chero zvisina kujairika maitiro mamiriro ayo anogona kumisa sarudzo yako ye membrane (semuenzaniso tembiricha).
