| H103 | Post Crosslink styrene yokhala ndi DVB | Mdima wakuda mpaka wakuda Kuzungulira | 1000-1100 | 0.5-1.0TOC / g100mg / ml | 50-60% | 0.3-1.2 | 670-690 |
Macroporous kumamatira utomoni ndi mtundu wa polima kumamatira utomoni popanda gulu kuwombola ndi dongosolo macroporous. Ili ndi mawonekedwe abwino a ma macroporous komanso malo akulu. Itha kusankha zotsatsa zinthu zakuthupi mumayendedwe amadzimadzi kudzera pakubwezeretsa thupi. Ndi mtundu watsopano wa organic polima adsorbent wopangidwa m'ma 1960. Amagwiritsidwa ntchito kwambiri poteteza zachilengedwe, chakudya, mankhwala ndi zina.
Macroporous adsorption resin nthawi zambiri imakhala yoyera tinthu tating'onoting'ono tokhala ndi tinthu tating'onoting'ono ta 20-60 mesh. Ma macrospheres a macroporous adsorption resin amapangidwa ndi magawo angapo ang'onoang'ono okhala ndi mabowo wina ndi mnzake.
Utomoni wa macroporous adsorption udasinthidwa ndi styrene, divinylbenzene, ndi zina mu 0,5% yankho la gelatin ndi gawo lina la porogen. Styrene imagwiritsidwa ntchito ngati monomer, divinylbenzene ngati othandizira, toluene ndi xylene ngati porogens. Analumikizidwa ndi ma polima kuti apange mawonekedwe oyipa a utomoni wa macroporous.
Kusankhidwa kwa kubwezeredwa kwa zinthu ndi kukonzanso kotsekemera kumakhudza mwachindunji mtundu wa njira yoberekera ya macroporous resorption resin, chifukwa chake zinthu zingapo ziyenera kuganiziridwa munthawi yonseyi kuti mudziwe momwe zimakhalira posungunuka ndi kutayika koyenera. Pali zinthu zambiri zomwe zimakhudza utomoni kumamatira, monga zinthu zomwe zimasiyanitsidwa ndi zinthu zina (polarity ndi kukula kwa ma molekyulu), zomwe zimatha kutsitsa zosungunulira (kusungunuka kwa zosungunulira kuzinthu zina, mchere wamchere ndi pH phindu), kuchuluka kwa njira yothetsera komanso kutulutsa madzi mlingo.
Nthawi zambiri, mamolekyu akuluakulu am'madzi am'madzi amatha kupatulidwa pa utomoni wapakatikati wa polar, ndipo mamolekyulu ang'onoang'ono a polar amatha kupatulidwa pa utomoni wosakhala wa polar; Kukula kwa voliyumu yayikulu, ndikukula kwa pore utomoni; Kutulutsa kwa utomoni kumatha kuwonjezeka powonjezera kuchuluka kwa mchere wosakanikirana mu njira yotsegula; Mavitamini a acidic ndiosavuta kutsitsidwa mu acidic solution, zopangira zofunikira ndizosavuta kutsitsidwa mu njira zamchere, ndipo mankhwala osalowerera ndale ndiosavuta kutsitsidwa munjira yandale; Nthawi zambiri, kutsika kwa njira yothetsera vutoli, kumamveka bwino kutsatsa; Kusankha kwakuchepa, ndibwino kuwonetsetsa kuti utomoniwo umatha kulumikizana ndi yankho potsegula pakamamatira. Zinthu zomwe zimakhudza kutsika kwa zinthu monga mtundu wa eluent, ndende, pH mtengo, kuthamanga kwake, ndi zina zotero. mphamvu ya zinthu zosiyanasiyana pa utomoni; Kusintha phindu la pH la eluent, mawonekedwe a adsorbent amatha kusintha, ndipo ndikosavuta kutulutsa; Kuchuluka kwa elution nthawi zambiri kumayendetsedwa pa 0.5-5ml / min.
Kukula kwa pore ndi mawonekedwe ake enieni a macroporous adsorption resin ndiokulirapo. Ili ndi mapangidwe atatu azithunzi za pore mkati mwa utomoni, womwe uli ndi maubwino ambiri monga kukhazikika kwakuthupi ndi mankhwala, malo akulu pamtunda, kutsegulira kwakukulu, kusankha bwino, kuthamanga kwakanthawi kofulumira, zinthu zofewa, kusintha kosavuta, kutalika kuzungulira kwa ntchito, koyenera kutsekedwa kwadongosolo komanso kupulumutsa ndalama.
