O lenei oloa e faʻaaogaina mo le faʻagogo loloto o le kesi poʻo le vai vai o petrochemicals ma faʻamago mea faigaluega.
25kg taga lalaga / 25kg pepa pa'u laupapa / 200L u'amea pa'u po o talosaga a tagata faatau.
O Meatotino Fausia OAlumina fa'agaoioia
Alumina fa'agaoioia o lo'o i ai uiga o le tele o le adsorption capacity, tele fa'apitoa i luga o le fogaeleele, malosi maualuga, ma le mautu lelei o le vevela. mea. E i ai se sootaga malosi, e le oona, e le corrosive aoga desiccant, ma lona gafatia static e maualuga. E fa'aaogaina e pei o le adsorbent, desiccant, catalyst ma le va'ava'a i le tele o gaioiga fa'afoliga e pei o le suau'u, vaila'au vaila'au ma alamanuia vaila'au.
O le alumina fa'agaoioia o se tasi lea o mea fa'aonaponei fa'aoga fa'aoga masani i le lalolagi. O mea totino o alumina faʻagaoioia o loʻo faʻamatalaina i lalo: O le alumina faʻagaoioia e lelei le mautu ma e talafeagai e pei o se desiccant, se faʻapipiʻi faʻapipiʻi, o se mea e aveese ai le fluorine, o se faʻapipiʻi faʻapipiʻi faʻamalosi, o se sui faʻapitoa toe faʻafouina mo le hydrogen peroxide, ma isi.
Alumina fa'agaoioia o lo'o fa'aaogaina e pei o se desiccant, e masani lava ona fa'aaogaina i masini fa'agogoina o masini fa'agogo, masini fa'agogo ea o lo'o i ai se mamafa galue, e masani lava i lalo ifo o le 0.8Mpa, lea e mana'omia ai le fua faatatau alumina fa'agaoioia e maua ai se malosi fa'ainisinia lelei, pe afai o le malosi fa'ainisinia e maualalo tele, e faigofie ona pa'u, pa'u ma vai fa'atasi o le a poloka sa'o le paipa meafaigaluega, o lea, O se fa'ailo taua o le fa'aogaina o le alumina fa'amamago meafaigaluega, e masani lava ona fa'aaogaina le fa'aogaina o le fa'aogaina o le fa'aogaina o le eletise, o le mea lea, O se fa'ailoga taua o le fa'aogaina o le alumina fa'amalosi e lua. tane, lua tane galue alternately, o le mea moni lava o se adsorption saturation → analytic faagasologa taamilosaga, desiccant e tele lava adsorption vai, ae i lalo o tulaga galue moni, ea mamafa faamago meafaigaluega puna ea o le a maua le suauu, ele ma isi eleelea, O nei mea o le a aafia tuusao le olaga o le alumina faagaoioia adsorbent, ona o le adsorption faagaioia o mea porous adsorption o le natura adsorption adsorption. e lelei tele foi, ae o le suauu o le a faʻapipiʻi saʻo alumina adsorption pore, ina ia leiloa o uiga adsorption, o loʻo i ai le ele, ele i le vai, faʻapipiʻi i luga o le alumina faʻagaoioia, O le a faia alumina faʻagaoioia saʻo leiloa gaoioiga, o lea i le alumina faʻagaoioia e pei o le desiccant faʻaoga, taumafai e aloese mai le faʻafesoʻotaʻi ma le suauu, ele, faʻaaogaina le alumina faʻaaogaina o le 1 tausaga, faʻaaogaina le alumina masani a le 3 tausaga, faʻaaogaina le alumina faʻaaogaina. fa'aoga o le a fa'amago le sau kasa e filifili ai pe sui le alumina fa'agaoioia. Ole vevela ole fa'afouina ole alumina fa'agaoioia ile va ole 180 ~ 350℃. E masani lava, o le vevela o le alumina o loʻo faʻaaogaina e siitia i le 280 ℃ mo le 4 itula. Fa'aaogaina alumina fa'aagaoioia e fai ma sui o le vai, ma fa'aaogaina le vaifofo alumini sulfate e fai ma toe fa'afouina. O le faʻatonuga o le faʻaogaina o le aluminium sulfate regenerator o le 2 ~ 3%, o le alumina faʻaagaoioia pe a uma ona tuʻuina le saturation adsorption i le faʻamaʻi alumini sulfate solution, lafoai le fofo, fufulu i le vai mama 3 ~ 5 taimi. A maeʻa le faʻaaogaina umi, o le alumina faʻaaogaina e lanu samasama enaena ma faʻaitiitia le aafiaga defluorination, lea e mafua mai i le adsorption o mea leaga. E mafai ona togafitia i le 3% hydrochloric acid mo le 1 taimi ona toe faʻafouina lea i le auala o loʻo i luga.
