Iimpawu ezisisiseko ze-zinc oxide:
◆Iimpawu zomzimba nezekhemikhali
I-zinc oxide, njenge-oxide ye-zinc, ibonisa iipropati ze-alkaline ze-amphoteric. Kunzima ukuyinyibilikisa emanzini, kodwa inokunyibilika lula kwii-asidi kunye neziseko eziqinileyo. Ubunzima bayo be-molecular yi-81.41 kwaye indawo yayo yokunyibilika ifikelela kwi-1975 ℃. Kubushushu begumbi, i-zinc oxide idla ngokubonakala njengeekristale ezine-hexagonal, ayinavumba kwaye ayinancasa, kwaye ineempawu ezizinzileyo. Kwintsimi yokutya, sisebenzisa ikakhulu ukuhlangana kwayo, ukufunxa, kunye neepropati zokulwa ne-antibacterial. Ukuyifaka kwisondlo samantshontsho eehagu akunakuphucula kuphela ukusebenza kwawo kokukhula, kodwa kukwathintela ngempumelelo iingxaki zawo zorhudo.

◆Umgaqo wokusebenza kunye nendlela yokusebenza
Iidosi eziphezulu ze-zinc oxide ziye zangqinwa ngokubanzi ukuba ziphucula ukusebenza kokukhula kwamantshontsho eehagu kwaye zithintele urhudo. Umgaqo wokusebenza kwayo ubangelwa kakhulu yimeko ye-molecular ye-zinc oxide (ZnO2), endaweni yezinye iintlobo ze-zinc. Esi sithako sisebenzayo sinokukhuthaza ngempumelelo ukukhula kwamantshontsho eehagu kwaye sinciphise kakhulu ukwanda korhudo. I-zinc oxide ikhuthaza ukukhula kwamantshontsho eehagu kunye nempilo yamathumbu ngokusebenzisa imeko yayo ye-molecular ye-ZnO2. Iidosi eziphezulu ze-ZnO2 ziyayinciphisa kwaye zidibanise i-asidi yesisu esiswini namathumbu amancinci, kwaye zifunxe iintsholongwane ezinobungozi, ziphucula ukusebenza kokukhula.

Kwindawo ene-asidi esiswini, i-zinc oxide iyangenaI-reaction ye-acid-base neutralization reaction ene-asidi yesisu, kwaye i-equation ye-reaction yile: ZnO+2H+→ Zn ² ⁺+H ₂ O. Oku kuthetha ukuba i-mole nganye ye-zinc oxide itya ii-moles ezimbini ze-hydrogen ions. Ukuba i-2kg/t ye-zinc oxide eqhelekileyo yongezwa kwisondlo sokufundisa samantshontsho eehagu, kwaye ukuba amantshontsho eehagu ancancisiweyo anokutya okutya kwemihla ngemihla kwe-200g, aza kudla i-0.4g ye-zinc oxide ngosuku, eyi-0.005 moles ye-zinc oxide. Ngale ndlela, ii-0.01 moles zee-hydrogen ions ziya kutyiwa, ezilingana ne-100 milliliters ye-acid yesisu ene-pH ye-1. Ngamanye amazwi, le nxalenye ye-zinc oxide (malunga ne-70-80%) esabela ne-acid yesisu iya kudla ii-70-80 milliliters ze-pH 1 acid yesisu, ebalelwa phantse kwi-80% ye-output iyonke ye-acid yesisu kwiintsana ezincancisiweyo. Ukutya okunjalo ngokuqinisekileyo kuya kuba nefuthe elikhulu ekugayweni kweproteni kunye nezinye izondlo kwisondlo.

Umngcipheko we-zinc oxide enedosi ephezulu:
Ngexesha lokulunyulwa kwamantshontsho eehagu, isixa esifunekayo se-zinc simalunga ne-100-120mg/kg. Nangona kunjalo, i-Zn²+ egqithisileyo inokukhuphisana nabathuthi bomphezulu beeseli ze-mucosal zamathumbu, ngaloo ndlela ithintela ukufunxwa kwezinye izinto ezifana ne-copper kunye ne-iron. Olu thintelo lokukhuphisana luphazamisa ibhalansi yezinto ezifunxwayo emathunjini, nto leyo ekhokelela ekuthintelweni kokufunxwa kwezinye izondlo. Uphando lubonise ukuba iidosi eziphezulu ze-zinc oxide zinciphisa kakhulu ukufunxwa kwezinto ze-iron emathunjini, ngaloo ndlela zichaphazela ukwakheka kunye nokuhlanganiswa kwe-hemoglobin. Kwangaxeshanye, i-zinc oxide eneedosi eziphezulu inokubangela ukuveliswa okugqithisileyo kwe-metallothionein, ebopha ngokukhethekileyo kwi-ions ze-copper, nto leyo ekhokelela ekuswelekeni kwe-copper. Ukongeza, ukunyuka okukhulu kwamanqanaba e-zinc kwisibindi kunye nezintso kunokubangela iingxaki ezifana ne-anemia, ulusu olukhanyayo, kunye neenwele ezirhabaxa.

◆Impembelelo kwi-asidi yesisu kunye nokugaya iiproteni
I-Zinc oxide, njengesithako se-alkaline kancinci, inexabiso le-asidi eliyi-1193.5, yesibini emva komgubo welitye (ixabiso le-asidi eliyi-1523.5), kwaye ikwinqanaba eliphezulu kwizixhobo ezikrwada zokutya. Iidosi eziphezulu ze-zinc oxide zitya isixa esikhulu se-asidi yesisu, zithintela ukugaya iiproteni, kwaye zichaphazela ukugaya kunye nokufunxwa kwezinye izondlo. Ukutya okunjalo ngokuqinisekileyo kuya kuba nefuthe elikhulu ekugayweni kweeproteni kunye nezinye izondlo ekutyeni.

◆Imiqobo ekufunxeni ezinye izondlo
I-Zn²+ egqithisileyo ikhuphisana nokufunxwa kwezondlo, ichaphazela ukufunxwa kwezinto ezincinci ezifana nesinyithi kunye nobhedu, ngaloo ndlela ichaphazela ukwenziwa kwe-hemoglobin kwaye ibangele iingxaki zempilo ezifana ne-anemia.
◆I-apoptosis yeeseli ze-mucosal zamathumbu
Uphando lutyhile ukuba ukuxinana okukhulu kwe-Zn²+ kwiiseli ze-mucosal zamathumbu kunokukhokelela kwi-cell apoptosis kwaye kuphazamise imeko ezinzileyo yeeseli zamathumbu. Oku akuchaphazeli nje kuphela umsebenzi oqhelekileyo wee-enzymes eziqulethe i-zinc kunye nezinto ezibangela ukubhalwa kwezakhi zofuzo, kodwa kukwanyusa ukufa kweeseli, okukhokelela kwiingxaki zempilo yamathumbu.

◆Impembelelo ye-ion ze-zinc kwindalo esingqongileyo
Ii-ion ze-zinc ezingafunxwanga ngokupheleleyo ngamathumbu ekugqibeleni ziya kukhutshwa kunye nendle. Le nkqubo ikhokelela ekwandeni okukhulu koxinzelelo lwe-zinc kwindle, nto leyo ebangela ukuba kukhutshwe inani elikhulu lee-ion ze-zinc ezingafunxwanga, nto leyo ebangela ungcoliseko lokusingqongileyo. Olu ninzi lokukhupha ii-ion ze-zinc lunokubangela ukuxinana komhlaba kuphela, kodwa lukwakhokelela kwiingxaki zokusingqongileyo ezifana nongcoliseko lwesinyithi esinzima emanzini angaphantsi komhlaba.

Iingenelo ze-zinc oxide ekhuselayo kunye nemveliso:
◆Iziphumo ezilungileyo ze-zinc oxide ekhuselayo
Uphuhliso lweemveliso ze-zinc oxide ezikhuselayo lujolise ekusebenziseni ngokupheleleyo isiphumo sokulwa norhudo se-zinc oxide. Ngeenkqubo ezikhethekileyo zokukhusela, i-zinc oxide engaphezulu yemolekyuli inokufikelela emathunjini, ngaloo ndlela isebenzise isiphumo sayo sokulwa norhudo kwaye iphucule ukusebenza kakuhle kokusetyenziswa kwe-zinc oxide. Le ndlela yokongeza idosi ephantsi inokufezekisa isiphumo sokulwa norhudo se-zinc oxide enedosi ephezulu. Ukongeza, le nkqubo inokunciphisa impendulo phakathi kwe-zinc oxide kunye ne-asidi yesisu, inciphise ukusetyenziswa kwe-H+, iphephe ukuveliswa okugqithisileyo kwe-Zn ²+, ngaloo ndlela iphucule ukugaya kunye nesantya sokusebenzisa iproteni, ikhuthaze ukusebenza kokukhula kwamantshontsho eehagu, kwaye iphucule imeko yoboya bawo. Uvavanyo olongezelelweyo lwezilwanyana luqinisekisile ukuba i-zinc oxide ekhuselayo inokunciphisa ukusetyenziswa kwe-asidi yesisu kumantshontsho eehagu, iphucule ukugaya izondlo ezifana nezinto ezomileyo, i-nitrogen, amandla, njl.njl., kwaye yonyuse kakhulu ubunzima bemihla ngemihla kunye nomlinganiselo wenyama ukuya kokutya kwamantshontsho eehagu.

◆Ixabiso lemveliso kunye neenzuzo ze-zinc oxide:
Ukuphucula ukugaywa kokutya kunye nokusetyenziswa kwako, ngaloo ndlela kukhuthaza ukuphuculwa kokusebenza kwemveliso; Kwangaxeshanye, kunciphisa ngempumelelo ukwanda kwesifo sorhudo kwaye kukhusela impilo yamathumbu.
Ukuze amantshontsho eehagu akhule kamva, le mveliso inokuphucula kakhulu ukukhula kwawo kwaye isombulule iingxaki ezifana nolusu olumhlophe kunye neenwele ezirhabaxa.
Uyilo olukhethekileyo lokongeza izinto eziphantsi alunciphisi nje kuphela umngcipheko we-zinc egqithisileyo, kodwa lukwanciphisa ungcoliseko olunokubakho lokukhutshwa kwe-zinc ephezulu kwindalo esingqongileyo.
