Izici eziyisisekelo ze-zinc oxide:
◆Izakhiwo zomzimba nezamakhemikhali
I-zinc oxide, njenge-oxide ye-zinc, ibonisa izakhiwo ze-alkaline ze-amphoteric. Kunzima ukuyincibilikisa emanzini, kodwa ingancibilika kalula kuma-acid kanye nezisekelo eziqinile. Isisindo sayo sama-molecule singama-81.41 kanti iphuzu layo lokuncibilika lifinyelela ku-1975 ℃. Ezingeni lokushisa legumbi, i-zinc oxide ivame ukubonakala njengamakristalu ayisithupha, ayinaphunga futhi ayinambitheki, futhi inezakhiwo ezizinzile. Emkhakheni wokudla, sisebenzisa kakhulu ukuhlangana kwayo, ukumuncwa kwayo, kanye nezakhiwo zokulwa namagciwane. Ukuyifaka ekudleni kwamaphuphu engulube akugcini nje ngokuthuthukisa ukusebenza kwawo kokukhula, kodwa futhi kuvimbela ngempumelelo izinkinga zawo zohudo.

◆Umgomo kanye nendlela yokusebenza
Imithamo ephezulu ye-zinc oxide iye yafakazelwa kabanzi ukuthi ithuthukisa ukusebenza kokukhula kwezingulube nokuvimbela uhudo. Isimiso sokusebenza kwayo sibangelwa kakhulu isimo sama-molecule e-zinc oxide (ZnO2), kunezinye izinhlobo ze-zinc. Lesi sithako esisebenzayo singakhuthaza ngempumelelo ukukhula kwezingulube futhi sinciphise kakhulu ukwanda kohudo. I-zinc oxide ikhuthaza ukukhula kwezingulube kanye nempilo yamathumbu ngesimo sayo sama-molecule i-ZnO2. Imithamo ephezulu ye-ZnO2 inciphisa futhi ihlanganise i-asidi yesisu esiswini nasemathunjini amancane, futhi imunce amabhaktheriya ayingozi, ithuthukise ukusebenza kokukhula.

Endaweni ene-asidi esiswini, i-zinc oxide iyangenaUkusabela kokungathathi hlangothi kwe-acid-base ne-asidi yesisu, kanti i-equation yokusabela ithi: ZnO+2H+→ Zn ² ⁺+H ₂ O. Lokhu kusho ukuthi yonke i-mole ye-zinc oxide idla ama-moles amabili ama-ion e-hydrogen. Uma i-2kg/t ye-zinc oxide ejwayelekile ingezwa ekudleni okufundisayo kwama-piglens, futhi uma sicabanga ukuthi ama-piglens aphunyuliwe anokudla kwansuku zonke okungu-200g, azodla u-0.4g we-zinc oxide ngosuku, okungu-0.005 moles we-zinc oxide. Ngale ndlela, kuzodliwa ama-moles angu-0.01 ama-ion e-hydrogen, okulingana cishe nama-milliliters ayi-100 e-asidi yesisu ene-pH engu-1. Ngamanye amazwi, le ngxenye ye-zinc oxide (cishe u-70-80%) ephendula ne-asidi yesisu izodla ama-milliliters angu-70-80 e-pH 1 ye-asidi yesisu, ebalelwa cishe ku-80% we-output iyonke ye-asidi yesisu nsuku zonke kuma-piglens aphunyuliwe. Ukusetshenziswa okunjalo ngokungangabazeki kuzoba nomthelela omkhulu ekugayweni kwamaprotheni nezinye izakhamzimba ekudleni.

Ingozi ye-zinc oxide eningi:
Ngesikhathi sokulunyulwa kwamaphuphu ezingulube, inani elidingekayo le-zinc lingaba ngu-100-120mg/kg. Kodwa-ke, i-Zn²+ eningi kakhulu ingancintisana nabathuthi bamaseli e-mucosal amathumbu, ngaleyo ndlela ivimbele ukumuncwa kwezinye izakhi ezifana nethusi nensimbi. Lokhu kuvinjelwa okuncintisanayo kuphazamisa ibhalansi yezakhi ezilandelanayo emathunjini, okuholela ekuvinjelweni kokumuncwa kwezinye izakhamzimba. Ucwaningo lukhombisile ukuthi imithamo ephezulu ye-zinc oxide inciphisa kakhulu ukumuncwa kwezakhi zensimbi emathunjini, ngaleyo ndlela ithinta ukwakheka kanye nokwakheka kwe-hemoglobin. Ngesikhathi esifanayo, i-zinc oxide eningi kakhulu ingadala nokukhiqizwa ngokweqile kwe-metallothionein, ebopha ngokukhethekile kuma-ion ethusi, okuholela ekusweleni kwethusi. Ngaphezu kwalokho, ukwanda okukhulu kwamazinga e-zinc esibindini nasezinso kungadala nezinkinga ezifana ne-anemia, isikhumba esimpunga, kanye nezinwele eziqinile.

◆Imiphumela ekugayweni kwe-asidi yesisu kanye namaprotheni
I-zinc oxide, njengento e-alkaline kancane, inenani le-acidity elingu-1193.5, elesibili ngemuva kwempuphu yamatshe (inani le-acidity elingu-1523.5), futhi ingaphansi kwezinga eliphezulu kakhulu ezintweni zokusetshenziswa zokudla. Imithamo ephezulu ye-zinc oxide idla inani elikhulu le-acid esiswini, ivimbela ukugaya kwamaprotheni, futhi ithinta ukugaya kanye nokumuncwa kwezinye izakhamzimba. Ukusetshenziswa okunjalo ngokungangabazeki kuzoba nomthelela omkhulu ekugayweni kwamaprotheni nezinye izakhamzimba ekudleni.

◆Izithiyo zokumuncwa kwezinye izakhamzimba
I-Zn²+ eningi kakhulu incintisana nokumuncwa kwezakhamzimba, ithinta ukumuncwa kwezinto ezincane njengensimbi nethusi, ngaleyo ndlela ithinte ukwakheka kwe-hemoglobin futhi ibangele izinkinga zempilo ezifana ne-anemia.
◆I-apoptosis yamaseli e-mucosal yamathumbu
Ucwaningo luveze ukuthi ukugcwala ngokweqile kwe-Zn²+ kumaseli e-mucosal amathumbu kungaholela ekuqhekekeni kwamaseli futhi kuphazamise isimo esizinzile samaseli amathumbu. Lokhu akugcini nje ngokuthinta umsebenzi ojwayelekile wama-enzyme aqukethe i-zinc kanye nezinto zokubhala, kodwa futhi kwenza ukufa kwamaseli kube kubi kakhulu, okuholela ezinkingeni zempilo yamathumbu.

◆Umthelela we-zinc ion endaweni ezungezile
Ama-ion e-zinc angamuncwa ngokuphelele amathumbu azogcina ekhishwe kanye nendle. Le nqubo iholela ekwandeni okukhulu kokugcwala kwe-zinc endle, okuholela ekukhishweni kwenani elikhulu lama-ion e-zinc angamuncwanga, okubangela ukungcola kwemvelo. Leli nani elikhulu lokukhishwa kwama-ion e-zinc kungase kungagcini nje ngokubangela ukuminyana kwenhlabathi, kodwa futhi kuholele ezinkingeni zemvelo ezifana nokungcola kwensimbi esindayo emanzini angaphansi komhlaba.

Izinzuzo ze-zinc oxide evikelayo kanye nomkhiqizo:
◆Imiphumela emihle ye-zinc oxide evikelayo
Ukuthuthukiswa kwemikhiqizo ye-zinc oxide evikelayo kuhloswe ukusebenzisa ngokugcwele umphumela wokulwa nohudo we-zinc oxide. Ngezinqubo ezikhethekile zokuvikela, i-zinc oxide eningi yama-molecule ingafinyelela emathunjini, ngaleyo ndlela isebenzise umphumela wayo wokulwa nohudo futhi ithuthukise ukusebenza kahle kokusetshenziswa kwe-zinc oxide. Le ndlela yokwengeza umthamo ophansi ingafinyelela umphumela wokulwa nohudo we-zinc oxide evimbela uhudo. Ngaphezu kwalokho, le nqubo inganciphisa futhi ukusabela phakathi kwe-zinc oxide ne-asidi yesisu, inciphise ukusetshenziswa kwe-H+, igweme ukukhiqizwa ngokweqile kwe-Zn ²+, ngaleyo ndlela ithuthukise ukugaya kanye nesilinganiso sokusetshenziswa kwamaprotheni, ikhuthaze ukusebenza kokukhula kwama-piglens, futhi ithuthukise isimo soboya bawo. Ukuhlolwa okwengeziwe kwezilwane kuqinisekisile ukuthi i-zinc oxide evikelayo inganciphisa ngempela ukusetshenziswa kwe-asidi yesisu kuma-piglens, ithuthukise ukugaya izakhamzimba ezifana nezinto ezomile, i-nitrogen, amandla, njll., futhi yandise kakhulu ukukhuluphala kwansuku zonke kanye nesilinganiso senyama nokondla kwama-piglens.

◆Inani lomkhiqizo kanye nezinzuzo ze-zinc oxide:
Thuthukisa ukugayeka kokudla kanye nokusetshenziswa kwako, ngaleyo ndlela kukhuthaze ukuthuthukiswa kokusebenza kokukhiqiza; Ngesikhathi esifanayo, kunciphisa ngempumelelo ukwanda kohudo futhi kuvikela impilo yamathumbu.
Ukuze amaphuphu amancane akhule kamuva, lo mkhiqizo ungathuthukisa kakhulu ukukhula kwawo futhi uxazulule izinkinga ezifana nesikhumba esimpunga nezinwele ezimahhadlahhadla.
Umklamo oyingqayizivele wokwengeza okuphansi awunciphisi nje kuphela ingozi ye-zinc eningi, kodwa futhi unciphisa ukungcola okungenzeka kokukhishwa kwe-zinc ephezulu emvelweni.
