I-resin yokushintshanisa eyisisekelo ebuthakathaka

Ebuthakathaka Isisekelo I-Anion (WBA) inhlakas are i-polymer eyenziwe nge-polymerizing styrene noma i-acrylic acid ne-divinylbenzene kanye ne-chlorination,ukuzijabulisa. Inkampani yeDongli ingahlinzeka nge-gel ne-macroporous izinhlobo WBA izinhlaka ezinama-crosslink ahlukile. I-WBA yethu iyatholakala ngezilinganiso eziningi kufaka phakathi amafomu e-Cl, usayizi ofanayo nebanga lokudla.

I-GA313, MA301, MA301G, MA313

I-resin exchange resion eyisisekelo ebuthakathaka: lolu hlobo lwe-resin luqukethe amaqembu ayisisekelo, njengeqembu eliyinhloko le-amino (elaziwa futhi njengeqembu eliyinhloko lama-amino) - i-NH2, iqembu lesibili lama-amino (iqembu lesibili lama-amino) - i-NHR, noma iqembu le-amino ephakeme (i-tertiary amino group - NR2. Bangakwazi ukuhlukanisa u-Oh - emanzini futhi basisekelo esibuthakathaka. Ezimweni eziningi, i-resin ikhangisa ngawo wonke amanye ama-molecule e-asidi esixazululweni. Ingasebenza kuphela ngaphansi kwezimo ezingathathi hlangothi noma ezine-asidi (njenge-pH 1-9). Ingavuselelwa kabusha ngeNa2CO3 ne-NH4OH.

Ukususwa Kokungcola
Imikhiqizo yezimboni ye-ion exchange resin imvamisa iqukethe inani elincane le-polymer eliphansi nelingasebenzi, kanye nokungcola okungaphili okunjenge-iron, lead kanye nethusi. Lapho i-resin ixhumana namanzi, i-asidi, i-alkali noma ezinye izixazululo, izinto ezingenhla zizodluliselwa kusixazululo, sithinte ikhwalithi yamanzi angcolile. Ngakho-ke, i-resin entsha kufanele yenziwe ngaphambi kokusebenzisa. Ngokuvamile, amanzi asetshenziselwa ukwenza i-resin ikhule ngokugcwele, bese kuthi, ukungcola okungaphili (ikakhulukazi izinhlanganisela zensimbi) kungasuswa ngo-4-5% thela i-hydrochloric acid, futhi ukungcola okungokwemvelo kungasuswa ngo-2-4% thela i-sodium hydroxide Isixazululo. Uma isetshenziselwa ukulungiswa kwemithi, kufanele ifakwe ku-ethanol.

Ukwelashwa Kwesikhathi Sokuqalisa
Ekusetshenzisweni kwe-resin, kuyadingeka ukuvimbela ukuxhumana nokungcola kukawoyela, i-organic molecular microorganism, i-oxidant eqinile nezinye izinsimbi (njenge-iron, ithusi, njll.) Ukugwema ukunciphisa amandla wokushintshaniswa kwe-ion noma ukulahlekelwa umsebenzi. Ngakho-ke, i-resin kufanele yenziwe isebenze ngokungajwayelekile ngokwesimo. Indlela yokwenza kusebenze inganqunywa ngokuya ngesimo nezimo zokungcola. Ngokuvamile, i-resin ye-cation kulula ukuthi ingcoliswe ngu-Fe ekuthambiseni ngokucwiliswa kwe-hydrochloric acid, Bese ugeze kancane kancane, i-resin ye-anion kulula ukungcoliswa yizinto eziphilayo. Ingamanziswa noma igezwe nge-10% NaCl + 2-5% NaOH isixazululo esihlanganisiwe. Uma kunesidingo, ingafakwa ku-1% isisombululo se-hydrogen peroxide imizuzu eminingana. Okunye, futhi kungasebenzisa enye indlela yokwelashwa kwe-acid, ukwelashwa okweqa iblich, ukwelashwa kotshwala nezindlela ezahlukahlukene zokuvala inzalo.

Ukuvuselelwa okusha kwe-Resin
Ukulungiswa kabusha kwe-resin entsha: emikhiqizweni yezimboni ye-ion exchange resin, kukhona inani elincane lama-oligomers nama-monomers angabambi iqhaza ekuphenduleni, futhi aqukethe nokungcola okungaphili okufana nensimbi, umthofu nethusi. Lapho i-resin ixhumana namanzi, i-asidi, i-alkali noma esinye isisombululo, izinto ezingenhla zizodluliselwa kusixazululo, okuzothinta ikhwalithi yokungcola. Ngakho-ke, i-resin entsha kufanele ilashwe ngaphambi kokusetshenziswa. Ngokuvamile, i-resin izokwanda ngamanzi, bese ukungcola okungajwayelekile (ikakhulukazi izinhlanganisela zensimbi) kungasuswa ngo-4-5% thela i-hydrochloric acid, futhi ukungcola okungokwemvelo kungasuswa ngo-2-4% wehlisa isisombululo se-sodium hydroxide ukuze ugezwe ukusondela kokungathathi hlangothi.
