Pazasi pane sumo pfupi pamusoro penzira dzekuita nadzo, mhando pamwe nekuongorora kwakanyorwa murondedzero yemishonga yakasiyana-siyana inochengetedza.
1.Maitiro ese ekuitazvinochengetedza
Zvinochengetedza zvinhu zvinonyanya kushandiswa mumakemikari anobatsira kuuraya kana kudzivirira mashandiro etupukanana muzvizoro pamwe nekuchengetedza mhando yese yezvizoro kwenguva yakareba.
Zvisinei, zvinofanira kucherechedzwa kuti mishonga yekuchengetedza haisi mushonga unouraya utachiona nekuti haina simba guru rekuuraya utachiona, uye inoshanda chete kana ikashandiswa yakawanda zvakakwana kana kuti ikasangana netupukanana.
Zvinodzivirira zvinodzivisa kukura kwehutachiona, zvichivharira kugadzirwa kwema enzymes akakosha ekugadzirisa metabolic pamwe nekudzivisa kugadzirwa kwemapuroteni muzvikamu zvakakosha zvemasero kana kugadzirwa kwe nucleic acid.
2.Zvinhu Zvinokanganisa Mabasa eZvinodzivirira
Zvinhu zvakawanda zvinobatsira pakushanda kwemishonga yekuchengetedza. Zvinosanganisira;
a.Mhedzisiro ye pH
Kuchinja kwepH kunobatsira mukuparadzana kwezvinodzivirira zve organic acid, uye nokudaro kunokanganisa kushanda kwezvinodzivirira. Semuenzaniso, pa pH 4 ne pH 6, 2-bromo-2-nitro-1,3-propanediol yakagadzikana zvikuru.
b.Mhedzisiro yegel nezvidimbu zvakasimba
Koalin, magnesium silicate, aruminiyamu nezvimwewo, zvimwe zvinhu zveupfu zvinowanikwa mune zvimwe zvizoro, izvo zvinowanzo tora zvinochengetedza uye zvichikonzera kurasikirwa nebasa nezvinochengetedza. Zvisinei, zvimwe zvinoshandawo mukunwisa mabhakitiriya ari muzvinochengetedza. Zvakare, kusanganiswa kwegel yepolymer inonyungudika mumvura uye zvinochengetedza zvinobatsira mukuderedza kuwanda kwezvinochengetedza zvasara mukugadzirwa kwezvizoro, uye izvi zvakaderedzawo kushanda kwezvinochengetedza.
c.Kunyungudika kwemhedzisiro ye nonionic surfactants
Kunyungudika kwemasurfactants akasiyana-siyana akadai se nonionic surfactants muzvichengetedzo kunokanganisawo mashandiro ese ema preservatives. Zvisinei, ma nonionic surfactants anonyungudika mumafuta akadai seHLB=3-6 anozivikanwa kuti ane mukana wepamusoro wekudzima mashandiro ezvichengetedzo zvichienzaniswa nema nonionic surfactants anonyungudika mumvura ane HLB yakakwira.
d.Mhedzisiro yekuora kwekuchengetedza
Kune zvimwe zvinhu zvakaita sekupisa, chiedza nezvimwewo, zvinokonzera kuora kwemishonga yekuchengetedza, zvichikonzera kudzikira kwesimba rayo rekuuraya utachiona. Zvimwe zvezvikonzero izvi zvinotungamira kukuita kwemakemikari mumuviri nekuda kwekupiswa nemwaranzi uye kupiswa kwehutachiona.
e.Mamwe mabasa
Saizvozvowo, zvimwe zvinhu zvakaita sekuvapo kwezvinonaka uye zvinokuvadza uye kupararira kwezvinochengetedza mumvura ine mafuta-zvikamu zviviri zvichabatsirawo mukudzikira kwebasa rezvinochengetedza kusvika pamwero wakati.
3.Hunhu hwemishonga inouraya utachiona hwezvinodzivirira
Hunhu hwemishonga inouraya utachiona mumishonga inochengetedza hunokosha kufunga nezvahwo. Kuva nemishonga inochengetedza yakawanda muzvizoro kuchaita kuti inyanye kutsamwa, nepo kushomeka kwehuwandu hwemishonga kunozokanganisa mishonga inouraya utachiona.hunhu hwezvinochengetedzaNzira yakanakisisa yekuongorora izvi ndeyekushandisa bvunzo yekuongorora njodzi yemuviri inosanganisira minimum inhibitory concentration (MIC) uye bvunzo yenzvimbo yekudzivirira.
Bvunzo yedenderedzwa reBacteriostatic: Bvunzo iyi inoshandiswa kuona mabhakitiriya nemould zvinokwanisa kukura nekukurumidza mushure mekurima panzvimbo yakakodzera. Mumamiriro ezvinhu apo dhisiki repepa rekusefa rakazadzwa nechinhu chinochengetedza rakadonhedzwa pakati peplate yepakati yekurima, pachava nedenderedzwa remabhakitiriya rakaumbwa rakatenderedza nekuda kwekupinda kwechinhu chinochengetedza. Pakuyera dhayamita yedenderedzwa remabhakitiriya, rinogona kushandiswa sechiyero chekuona kushanda kwechinhu chinochengetedza.
Neizvi, zvinogona kutaurwa kuti denderedzwa remabhakitiriya richishandisa nzira yepepa ine dhayamita >=1.0mm rinoshanda zvikuru. MIC inonzi huwandu hushoma hwekuchengetedza hunogona kuwedzerwa mune imwe nzira yekudzivirira kukura kwehutachiona. Mumamiriro ezvinhu akadaro, MIC diki, ndipo panowedzera simba rekuchengetedza utachiona.
Simba kana mhedzisiro yekushanda kwemishonga inorwisa utachiona inowanzoonekwa muchimiro cheminimum inhibitory concentration (MIC). Nekuita izvi, simba rekushandisa mishonga inorwisa utachiona rinobva pakukosha kudiki kweMIC. Kunyangwe MIC isingakwanise kushandiswa kusiyanisa pakati pebasa rekuuraya utachiona nerekudzivirira utachiona, ma surfactants anozivikanwa kuti ane simba rekudzivirira utachiona pahuwandu hushoma uye sterilization effect pahuwandu hwakawanda.
Kutaura zvazviri, panguva dzakasiyana, zviitiko zviviri izvi zvinoitika panguva imwe chete, uye izvi zvinoita kuti zviome kusiyanisa. Nekuda kweizvi, zvinowanzopihwa zita rekuti kuuraya utachiona kana kungoti kuuraya utachiona.
