Ake ngithule i-SAP ukuthi unesithakazelo esikhulu kamuva! I-Super Absorbent Polyment (i-SAP) uhlobo olusha lwezinto ezisebenzayo ze-polymer. Inomsebenzi ophakeme wokutholwa kwamanzi amunca amanzi anamakhulu amahlandla ayizinkulungwane ezinde kakhulu kunawodwa, futhi enokusebenza okuhle kakhulu kokugcinwa kwamanzi. Uma ithola amanzi futhi ivuze i-hydrogel, kunzima ukuhlukanisa amanzi noma ngabe kucindezelwe. Ngakho-ke, inokusetshenziswa okuhlukahlukene emikhakheni ehlukahlukene efana nemikhiqizo yenhlanzeko yomuntu siqu, ukukhiqizwa kwezimboni nezolimo, kanye nobunjiniyela bomphakathi.
I-Super Ascenbent Resin uhlobo lwama-macromolecule aqukethe amaqembu e-hydrophilic kanye nesakhiwo esixhumeke kakhulu. Kwaqala ukukhiqizwa yi-fanta nabanye ngokuxhunyelelwa isitashi nge-pollicrylonitriteri bese kuthi ukusakazwa. Ngokwezinto zokwakha ezivuthiwe, kukhona uchungechunge lwesitashi (oluxhunyekwe, i-carboxyboxyletyleyleted, njll.) Uma kuqhathaniswa nesitashi kanye ne-cellulose, i-polyyacrylic acid superabsorbent resin inochungechunge lwezinzuzo ezinjengezindleko eziphansi zokukhiqiza, inqubo elula, amandla aphezulu okufakwa kwamanzi, kanye nempilo eqinile yeshelufu yeshelufu, kanye nempilo ende yomkhiqizo. Sekuphenduke i-hotspot yocwaningo lwamanje kulo mkhakha.
Uyini umgomo walo mkhiqizo? Kwezimanje, ama-polyacrylic acid account ama-80% wokukhiqizwa kwe-resin ye-supermunt emhlabeni. I-Super Anclusien Resin ngokuvamile i-electrolyte ye-polymer equkethe iqembu le-hydrophilic kanye nesakhiwo esixhumeke. Ngaphambi kokuthola amanzi, amaketanga e-polymer asondelene futhi angena ndawonye, axhumene nesakhiwo senethiwekhi, ukuze afeze ukubopha okuwohlokayo. Uma uhlangana namanzi, ama-molecule wamanzi angena e-resin ngesenzo se-capillary kanye nokuphazamiseka, namaqembu ama-ionesised on the cweach angowasetwe Ngenxa yokuxoshwa kwe-electrostatic phakathi kwama-oon afanayo kwi-chain, i-polymer chain yelula futhi ivuvukele. Ngenxa yesidingo sokungathathi hlangothi kukagesi, i-counter ion ayinakufudukela ngaphandle kwe-resin, kanye nomehluko ku-Ion okuhlushwa phakathi kwesisombululo ngaphakathi nangaphandle kwe-resin kwakha ingcindezi yokuphindisela okuhlangenwe nakho. Ngaphansi kwesenzo sokucindezela kwe-Osmosis kwe-reverse, amanzi aqhubeka angena e-resin ukwakha i-hydrogel. Ngasikhathi sinye, isakhiwo senethiwekhi exhumeke ngokuwela kanye nesibopho se-hydrogen se-resin ngokwayo silinganise ukwanda okungenamkhawulo kwejeli. Lapho amanzi equkethe inani elincane likasawoti, ukucindezela okubuyisela emuva kwe-osmotic kuzokwehla, futhi ngasikhathi sinye, ngenxa yomphumela wokuvikelwa kwe-Ion counter, okuholela ekunciphiseni okukhulu kwamandla wokutholwa kwamanzi we-resin. Ngokuvamile, umthamo wokufakwa kwamanzi we-Super Ancesbent Resin ku-0.9% NACL Solution ucishe abe ngu-1/10 kuphela wawo wamanzi we-deionized. Ukutholwa kwamanzi nokugcinwa kwamanzi kuyizici ezimbili zenkinga efanayo. I-LIN RUNXIONG et al. baxoxe ngabo ku-thermodynamics. Ngaphansi kokushisa okuthize kanye nengcindezi, i-resin etholwa kakhulu ingadonsa amanzi ngokuzenzakalelayo, futhi amanzi angena kwi-resin, ehlisa i-Entholpy yamahhala yalo lonke uhlelo kuze kube yilapho ifinyelela ekufezekisweni. Uma amanzi ephunyuka e-resin, andise i-Free ebutholweni, ayikufanele ukuqina kohlelo. Ukuhlaziywa okuhlukile okushisayo kukhombisa ukuthi ama-50% amanzi adonswa yi-Super Anclen Resin asafakwa kunethiwekhi ye-gel ngaphezulu kwe-150 ° C. Ngakho-ke, noma ngabe ingcindezi isetshenziswa ekushiseni okujwayelekile, amanzi ngeke aphunyuke ku-resin emunca amandla, enqunywa yizakhiwo ze-thermodynamic ze-resin e-super surbent.
Ngokuzayo, Tel inhloso ethile ye-sap.
