Kuchengetera Yekusapinda Mvura Uye Inofema Membrane
Kana iyo membrane yakachengetwa kwenguva yakareba, inofanirwa kuchengetedza kushanda kwakanaka uye ine kukosha kwekushandisa, saka hupenyu hwemvura uye inofema membrane inyaya yakakosha. Nokudaro, kunyanya kukoshesa kunofanira kubhadharwa kune chaiyo yekuchengetedza.
Kuchengetedzwa kwemvura uye inofema microfiltration membrane yakakamurwa kuva nzira mbiri: kunyorova kuchengetedza uye kuoma kuchengetedza. Chero nzira, chinangwa ndechekudzivirira membrane kubva kune hydrolyzed, kudzivirira kukura uye kukukurwa kwema microorganisms, uye shrinkage uye deformation ye membrane.
Chinokosha chekuchengetedzwa kwemvura ndeyekugara uchichengetedza membrane pamusoro nemhinduro yekuchengetedza munzvimbo ine unyoro. Iyo inotevera fomula inogona kushandiswa pakuchengetedza mhinduro: mvura: glycerin: formaldehyde = 79.5:20: 0.5. Basa re formaldehyde nderokudzivirira kukura uye kubereka kwe microorganisms pamusoro pe membrane uye kudzivirira kukukurwa kwe membrane. Chinangwa chekuwedzera glycerin ndechekuderedza nzvimbo yechando yegadziriro yekuchengetedza uye kudzivirira membrane kubva pakukuvadzwa nechando. Iyo formaldehyde muchimiro inogonawo kutsiviwa nemamwe fungicides akadai semhangura sulfate iyo isingakuvadzi kune membrane. Iyo tembiricha yekuchengetedza ye cellulose acetate membrane ndeye 5-40 ° C uye PH = 4.5 ~ 5, nepo tembiricha yekuchengetedza uye pH yeasiri-cellulose acetate membrane inogona kuve yakafara.
Dry Preservation
Isingapindi mvura uye inofema microfiltration membranes inowanzo kupihwa mumusika seyakaoma membrane nekuti ari nyore kuchengeta nekutakura. Mukuwedzera, iyo firimu yakanyorova inofanira kuchengetwa nenzira yakaoma, uye nzira dzinotevera dzinofanira kushandiswa kugadzirisa firimu isati yaenderera mberi. Iyo chaiyo nzira ndeye: iyo cellulose acetate membrane inogona kunyikwa mu50% glycerin aqueous solution kana 0.1% sodium lauryl sulfonate aqueous solution kwemazuva mashanu kusvika matanhatu, uye yakaomeswa pane imwe humidity ye88%. Iyo polysulfone membrane inogona kuomeswa pakupisa kwekamuri ine mhinduro ye10% glycerin, sulfonated mafuta, polyethylene glycol, nezvimwewo se dehydrating agent. Mukuwedzera, ma surfactants anewo maitiro akanaka ekudzivirira ma pores emufirimu kubva pakusvibiswa.
Chechipiri, kuchengetedza uye kuchengetedza kwemvura uye inofema membrane system inofanirwa kutariswa
Kuchengetedza uye kuchengetedza membrane system kunofanirwa kutarisa pane zvinotevera.
① Zvinoenderana neakasiyana membranes, kutarisisa kwakanyanya kunofanirwa kubhadharwa kune nharaunda yekushandisa, kunyanya tembiricha uye pH kukosha kweiyo mvura yemvura, uye kunyangwe iyo chlorine yemukati mune yemvura.
② Kana iyo membrane system ikamiswa kwenguva pfupi, kutarisisa kunofanirwa kubhadharwa kune kunyorova kwe membrane, nekuti kana iyo membrane ingorasikirwa nemvura, hapana chiyero chekugadzirisa, iyo isina mvura uye inofema membrane pores inoderera uye inodzima, ichaderedza kushanda kwe membrane.
③Paunomira, dzivirira kusangana nezvinwiwa zvakakwirira-concentration.
④ Geza uye chengetedza membrane nguva nenguva nemvura yekuchengetedza kuderedza kusvibiswa kwe membrane.
⑤ Mukushandiswa, shanda zvinoenderana nemamiriro ekushanda ayo membrane system inogona kumira kuti isaremerwa.
