Cov yam ntxwv tseem ceeb ntawm zinc oxide:
◆Cov khoom siv lub cev thiab tshuaj lom neeg
Zinc oxide, ua ib qho oxide ntawm zinc, muaj cov yam ntxwv amphoteric alkaline. Nws nyuaj rau yaj hauv dej, tab sis tuaj yeem yaj tau yooj yim hauv cov kua qaub thiab cov hauv paus muaj zog. Nws qhov hnyav molecular yog 81.41 thiab nws qhov chaw yaj yog siab txog 1975 ℃. Ntawm chav tsev kub, zinc oxide feem ntau tshwm sim ua cov siv lead ua hexagonal, tsis muaj ntxhiab thiab tsis qab, thiab muaj cov yam ntxwv ruaj khov. Hauv kev pub tsiaj, peb feem ntau siv nws cov khoom sib sau ua ke, kev nqus, thiab cov tshuaj tua kab mob. Ntxiv nws rau hauv cov pub tsiaj ntawm cov menyuam npua tsis tsuas yog txhim kho lawv txoj kev loj hlob, tab sis kuj tseem tiv thaiv lawv cov teeb meem raws plab.

◆Txoj cai ua haujlwm thiab txoj kev
Cov tshuaj zinc oxide ntau tau ua pov thawj dav dav tias nws tuaj yeem txhim kho kev loj hlob ntawm cov menyuam npua thiab tiv thaiv kev raws plab. Lub hauv paus ntsiab lus ntawm nws txoj haujlwm feem ntau yog vim lub xeev molecular ntawm zinc oxide (ZnO), es tsis yog lwm hom zinc. Cov khoom xyaw nquag no tuaj yeem txhawb kev loj hlob ntawm cov menyuam npua thiab txo qhov tshwm sim ntawm kev raws plab. Zinc oxide txhawb kev loj hlob ntawm cov menyuam npua thiab kev noj qab haus huv ntawm txoj hnyuv los ntawm nws lub xeev molecular ZnO. Cov tshuaj ZnO ntau ua rau cov kua qaub hauv plab thiab plab hnyuv tsis sib xyaw thiab sib sau ua ke, thiab nqus cov kab mob phem, txhim kho kev loj hlob.

Hauv cov kua qaub ntawm lub plab, zinc oxide raug rhuav tshem.kev sib xyaw ua ke ntawm cov kua qaub-puag nrog cov kua qaub hauv plab, thiab cov qauv sib npaug yog: ZnO + 2H + → Zn ² ⁺ + H ₂ O. Qhov no txhais tau tias txhua mole ntawm zinc oxide noj ob moles ntawm hydrogen ions. Yog tias ntxiv 2kg / t ntawm zinc oxide ib txwm rau hauv cov zaub mov pub rau cov menyuam npua, thiab xav tias cov menyuam npua tsis tau noj zaub mov txhua hnub ntawm 200g, lawv yuav noj 0.4g ntawm zinc oxide ib hnub, uas yog 0.005 moles ntawm zinc oxide. Ua li no, 0.01 moles ntawm hydrogen ions yuav raug noj, uas yog kwv yees li sib npaug rau 100 milliliters ntawm cov kua qaub hauv plab nrog pH ntawm 1. Hauv lwm lo lus, qhov no ntawm zinc oxide (kwv yees li 70-80%) uas cuam tshuam nrog cov kua qaub hauv plab yuav noj 70-80 milliliters ntawm pH 1 kua qaub hauv plab, uas suav txog yuav luag 80% ntawm tag nrho cov kua qaub hauv plab txhua hnub hauv cov menyuam npua tsis tau noj zaub mov. Kev noj zaub mov zoo li no yuav muaj kev cuam tshuam loj heev rau kev zom cov protein thiab lwm yam khoom noj muaj txiaj ntsig hauv cov khoom noj.

Qhov kev pheej hmoo ntawm kev siv zinc oxide ntau dhau:
Thaum lub sijhawm uas cov menyuam npua tsis noj mis, qhov yuav tsum tau noj zinc yog kwv yees li 100-120mg/kg. Txawm li cas los xij, Zn²+ ntau dhau tuaj yeem sib tw nrog cov neeg thauj khoom ntawm cov hlwb mucosal hauv plab hnyuv, yog li ntawd txwv tsis pub nqus lwm yam khoom xws li tooj liab thiab hlau. Qhov kev sib tw no cuam tshuam kev sib npaug ntawm cov khoom hauv plab hnyuv, ua rau kev cuam tshuam ntawm kev nqus lwm yam khoom noj khoom haus. Kev tshawb fawb tau qhia tias cov koob tshuaj zinc oxide ntau dhau ua rau txo qis kev nqus cov hlau hauv plab hnyuv, yog li cuam tshuam rau kev tsim thiab kev tsim hemoglobin. Tib lub sijhawm, cov koob tshuaj zinc oxide ntau dhau kuj tseem tuaj yeem ua rau muaj ntau dhau ntawm metallothionein, uas feem ntau khi rau cov ions tooj liab, ua rau tsis muaj tooj liab txaus. Tsis tas li ntawd, kev nce ntxiv ntawm cov zinc hauv daim siab thiab lub raum kuj tseem yuav ua rau muaj teeb meem xws li ntshav tsis txaus, tawv nqaij daj ntseg, thiab plaub hau ntxhib.

◆Cov teebmeem ntawm kev zom zaub mov hauv plab thiab cov protein
Zinc oxide, ua ib yam khoom alkaline me ntsis, muaj tus nqi acidity ntawm 1193.5, thib ob tsuas yog hmoov pob zeb (tus nqi acidity ntawm 1523.5), thiab yog ib qho khoom siv raw khoom noj khoom haus siab heev. Kev noj zinc oxide ntau dhau yuav noj ntau cov kua qaub hauv plab, cuam tshuam kev zom cov protein, thiab cuam tshuam rau kev zom thiab kev nqus ntawm lwm yam as-ham. Kev noj li no yuav muaj kev cuam tshuam loj heev rau kev zom cov protein thiab lwm yam as-ham hauv cov khoom noj.

◆Kev cuam tshuam rau kev nqus ntawm lwm cov as-ham
Zn ²+ ntau dhau sib tw nrog kev nqus cov as-ham, cuam tshuam rau kev nqus cov ntsiab lus me me xws li hlau thiab tooj liab, yog li cuam tshuam rau kev tsim hemoglobin thiab ua rau muaj teeb meem kev noj qab haus huv xws li ntshav tsis txaus.
◆Apoptosis ntawm cov hlwb mucosal hauv plab hnyuv
Kev tshawb fawb tau qhia tias kev muaj Zn²+ ntau dhau hauv cov hlwb ntawm txoj hnyuv tuaj yeem ua rau cov hlwb tuag thiab cuam tshuam rau qhov ruaj khov ntawm cov hlwb hauv txoj hnyuv. Qhov no tsis yog tsuas yog cuam tshuam rau kev ua haujlwm ib txwm ntawm cov enzymes uas muaj zinc thiab cov yam ntxwv sau ntawv xwb, tab sis kuj ua rau cov hlwb tuag ntau ntxiv, ua rau muaj teeb meem kev noj qab haus huv ntawm txoj hnyuv.

◆Kev cuam tshuam rau ib puag ncig ntawm zinc ions
Cov zinc ions uas txoj hnyuv tsis nqus tag nrho yuav raug tso tawm nrog cov quav. Cov txheej txheem no ua rau muaj kev nce ntxiv ntawm cov zinc hauv cov quav, ua rau muaj ntau cov zinc ions uas tsis tau nqus tawm, ua rau muaj kuab paug rau ib puag ncig. Cov zinc ions ntau no tsis yog tsuas yog ua rau av nruj xwb, tab sis kuj ua rau muaj teeb meem ib puag ncig xws li cov hlau hnyav hauv cov dej hauv av.

Kev tiv thaiv zinc oxide thiab cov khoom zoo:
◆Cov txiaj ntsig zoo ntawm kev tiv thaiv zinc oxide
Kev tsim cov khoom tiv thaiv zinc oxide lub hom phiaj yog siv tag nrho cov txiaj ntsig tiv thaiv kev raws plab ntawm zinc oxide. Los ntawm cov txheej txheem tiv thaiv tshwj xeeb, ntau cov zinc oxide molecular tuaj yeem ncav cuag txoj hnyuv, yog li ua rau nws cov txiaj ntsig tiv thaiv kev raws plab thiab txhim kho kev siv tag nrho ntawm zinc oxide. Txoj kev ntxiv qis no tuaj yeem ua tiav cov txiaj ntsig tiv thaiv kev raws plab ntawm cov zinc oxide siab. Tsis tas li ntawd, cov txheej txheem no kuj tseem tuaj yeem txo qhov kev sib xyaw ntawm zinc oxide thiab kua qaub hauv plab, txo kev noj H +, zam kev tsim ntau dhau ntawm Zn ² +, yog li txhim kho kev zom zaub mov thiab kev siv cov protein, txhawb kev loj hlob ntawm cov menyuam npua, thiab txhim kho lawv cov plaub hau zoo. Cov kev sim ntxiv ntawm cov tsiaj tau lees paub tias cov zinc oxide tiv thaiv tuaj yeem txo qhov kev noj kua qaub hauv plab hauv cov menyuam npua, txhim kho kev zom cov as-ham xws li cov khoom qhuav, nitrogen, zog, thiab lwm yam, thiab ua rau qhov hnyav nce txhua hnub thiab nqaij rau pub ntawm cov menyuam npua.

◆Tus nqi khoom thiab qhov zoo ntawm zinc oxide:
Txhim kho kev zom zaub mov thiab kev siv cov khoom noj, yog li txhawb kev txhim kho kev ua tau zoo ntawm kev tsim khoom; tib lub sijhawm, nws txo qhov tshwm sim ntawm kev raws plab thiab tiv thaiv kev noj qab haus huv ntawm txoj hnyuv.
Rau kev loj hlob tom qab ntawm cov menyuam npua, cov khoom no tuaj yeem txhim kho lawv txoj kev loj hlob thiab daws cov teeb meem xws li daim tawv nqaij daj thiab cov plaub hau ntxhib.
Qhov tsim tshwj xeeb uas tsis muaj zinc ntau dhau tsis yog tsuas yog txo qhov kev pheej hmoo ntawm zinc ntau dhau xwb, tab sis kuj txo qhov ua rau muaj kuab paug ntawm cov pa zinc ntau rau ib puag ncig.
