Cov yam ntxwv tseem ceeb ntawm zinc oxide:
◆Lub cev thiab tshuaj muaj zog
Zinc oxide, raws li oxide ntawm zinc, nthuav tawm amphoteric alkaline zog. Nws yog qhov nyuaj rau yaj hauv dej, tab sis tuaj yeem yooj yim yaj hauv cov kua qaub thiab cov hauv paus muaj zog. Nws qhov hnyav molecular yog 81.41 thiab nws qhov melting point yog siab li 1975 ℃. Nyob rau hauv chav tsev kub, zinc oxide feem ntau tshwm li hexagonal crystals, tsis muaj ntxhiab thiab tsis qab, thiab muaj cov khoom ruaj khov. Nyob rau hauv lub teb ntawm pub, peb tsuas yog siv nws convergence, adsorption, thiab antibacterial zog. Ntxiv rau qhov pub ntawm piglets tuaj yeem tsis tsuas yog txhim kho lawv txoj kev loj hlob, tab sis kuj tseem tiv thaiv lawv cov teeb meem raws plab.

◆Txoj hauv kev ua haujlwm thiab txoj hauv kev
Cov koob tshuaj ntau ntawm zinc oxide tau pom dav dav los txhim kho piglet kev loj hlob thiab tiv thaiv raws plab. Lub hauv paus ntsiab lus ntawm nws qhov kev ua yog feem ntau yog los ntawm lub xeev molecular ntawm zinc oxide (ZnO), es tsis yog lwm hom zinc. Cov khoom xyaw nquag no tuaj yeem txhawb txoj kev loj hlob ntawm piglets thiab txo qhov mob raws plab. Zinc oxide txhawb nqa piglet kev loj hlob thiab plab hnyuv noj qab haus huv los ntawm nws lub xeev molecular ZnO. Cov koob tshuaj ntau ntawm ZnO neutralize thiab converge gastric acid nyob rau hauv lub plab thiab cov hnyuv me, thiab nqus cov kab mob phem, txhim kho kev loj hlob.

Nyob rau hauv acidic ib puag ncig ntawm lub plab, zinc oxide undergoesacid-base neutralization cov tshuaj tiv thaiv nrog gastric acid, thiab qhov sib npaug ntawm cov tshuaj tiv thaiv yog: ZnO + 2H + → Zn ² ⁺ + H ₂ O. Qhov no txhais tau tias txhua mole ntawm zinc oxide siv ob moles ntawm hydrogen ions. Yog tias 2kg / t ntawm cov zinc oxide niaj zaus ntxiv rau kev kawm pub rau piglets, thiab xav tias cov piglets weaned tau noj txhua hnub ntawm 200g, lawv yuav noj 0.4g ntawm zinc oxide ib hnub, uas yog 0.005 moles ntawm zinc oxide. Nyob rau hauv txoj kev no, 0.01 moles ntawm hydrogen ions yuav tsum tau noj, uas yog kwv yees li sib npaug rau 100 milliliters ntawm plab acid nrog ib tug pH ntawm 1. Nyob rau hauv lwm yam lus, no feem ntawm zinc oxide (kwv yees li 70-80%) uas reacts nrog plab acid yuav noj 70-80 milliliters ntawm pH 1 plab acid, uas yuav luag 8% ntawm tag nrho cov acids nyob rau hauv lub plab txhua hnub. npua. Xws li kev noj yuav ua rau muaj kev cuam tshuam loj rau kev zom cov protein thiab lwm yam khoom noj hauv kev pub.

Kev pheej hmoo ntawm cov koob tshuaj zinc oxide:
Thaum lub sij hawm hws ntawm piglets, qhov xav tau ntawm zinc yog kwv yees li 100-120mg / kg. Txawm li cas los xij, ntau dhau Zn ² + tuaj yeem sib tw nrog cov chaw thauj khoom ntawm cov hnyuv mucosal, yog li inhibiting qhov nqus ntawm lwm cov kab mob xws li tooj liab thiab hlau. Qhov kev sib tw inhibition cuam tshuam qhov sib npaug ntawm cov kab mob hauv cov hnyuv, ua rau muaj kev cuam tshuam ntawm kev nqus ntawm lwm cov as-ham. Kev tshawb fawb tau pom tias cov zinc oxide ntau npaum li cas txo qhov nqus ntawm cov hlau hauv cov hnyuv, yog li cuam tshuam rau kev tsim thiab kev sib txuas ntawm hemoglobin. Nyob rau tib lub sijhawm, cov tshuaj zinc oxide ntau kuj tuaj yeem ua rau ntau dhau ntawm metallothionein, uas nyiam khi rau tooj liab ions, ua rau tooj liab tsis txaus. Tsis tas li ntawd, kev nce qib zinc nyob rau hauv daim siab thiab ob lub raum kuj tseem tuaj yeem ua rau muaj teeb meem xws li anemia, tawv nqaij daj, thiab cov plaub hau ntxhib.

◆Kev cuam tshuam rau gastric acid thiab protein digestion
Zinc oxide, raws li ib tug me ntsis alkaline tshuaj, muaj ib tug acidity tus nqi ntawm 1193.5, thib ob tsuas yog rau pob zeb hmoov (acidity tus nqi ntawm 1523.5), thiab belongs rau ib tug kuj siab nyob rau hauv cov ntaub ntawv raw khoom. Kev noj ntau ntawm zinc oxide noj ntau cov kua qaub hauv plab, cuam tshuam kev zom cov protein, thiab cuam tshuam rau kev zom zaub mov thiab kev nqus ntawm lwm cov as-ham. Xws li kev noj yuav ua rau muaj kev cuam tshuam loj rau kev zom cov protein thiab lwm yam khoom noj hauv kev pub.

◆Obstacles rau kev nqus ntawm lwm cov as-ham
Ntau Zn ² + sib tw nrog kev nqus cov khoom noj, cuam tshuam rau kev nqus ntawm cov kab mob xws li hlau thiab tooj liab, yog li cuam tshuam rau hemoglobin synthesis thiab ua rau muaj teeb meem kev noj qab haus huv xws li ntshav ntshav.
◆Apoptosis ntawm plab hnyuv mucosal hlwb
Kev tshawb fawb tau qhia tias ntau dhau ntawm Zn ² + nyob rau hauv cov hnyuv mucosal hlwb tuaj yeem ua rau cell apoptosis thiab cuam tshuam lub xeev ruaj khov ntawm cov hnyuv. Qhov no tsis tsuas yog cuam tshuam rau cov haujlwm ib txwm muaj ntawm zinc uas muaj cov enzymes thiab cov khoom hloov pauv, tab sis kuj ua rau cov cell tuag ntau dua, ua rau muaj teeb meem hauv plab hnyuv.

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

Kev tiv thaiv zinc oxide thiab cov khoom zoo:
◆Cov txiaj ntsig zoo ntawm kev tiv thaiv zinc oxide
Txoj kev loj hlob ntawm cov khoom tiv thaiv zinc oxide lub hom phiaj siv tag nrho cov tshuaj tiv thaiv raws plab ntawm zinc oxide. Los ntawm cov txheej txheem tiv thaiv tshwj xeeb, ntau molecular zinc oxide tuaj yeem ncav cuag txoj hnyuv, yog li siv nws cov tshuaj tiv thaiv kab mob thiab txhim kho kev siv tag nrho ntawm zinc oxide. Txoj kev siv tshuaj tsawg tsawg no tuaj yeem ua tiav cov nyhuv tiv thaiv kab mob ntawm cov tshuaj zinc oxide siab. Tsis tas li ntawd, cov txheej txheem no tseem tuaj yeem txo cov tshuaj tiv thaiv ntawm zinc oxide thiab lub plab acid, txo kev noj H +, tsis txhob ntau dhau ntawm Zn ² +, yog li txhim kho kev zom zaub mov thiab kev siv cov protein, txhawb kev loj hlob ntawm piglets, thiab txhim kho lawv cov plaub hau. Kev sim tsiaj ntxiv tau lees paub tias kev tiv thaiv zinc oxide tiag tiag tuaj yeem txo qis kev noj zaub mov hauv cov piglets, txhim kho kev zom cov khoom noj xws li cov khoom qhuav, nitrogen, lub zog, thiab lwm yam, thiab ua kom hnyav nce txhua hnub thiab cov nqaij noj rau cov piglets.

◆Cov khoom muaj nqis thiab qhov zoo ntawm zinc oxide:
Txhim kho kev noj zaub mov digestibility thiab kev siv, yog li txhawb kev txhim kho kev ua haujlwm ntau lawm; Nyob rau tib lub sijhawm, nws txo qis qhov tshwm sim ntawm raws plab thiab tiv thaiv txoj hnyuv.
Rau kev loj hlob tom qab ntawm piglets, cov khoom no tuaj yeem txhim kho lawv txoj kev loj hlob thiab daws teeb meem xws li tawv nqaij daj ntseg thiab cov plaub hau ntxhib.
Qhov tshwj xeeb qis ntxiv tsim tsis tsuas yog txo qhov kev pheej hmoo ntawm zinc ntau dhau, tab sis kuj txo qis qhov muaj kuab paug siab ntawm zinc emissions rau ib puag ncig.
