Comund Mechanism uye Yakagadzirirwa Kugadzirwa Kwekukuru uye Auxialary Antioxidants kurwisa afrul okisijeni kukwegura
Iyo anti-Thermal okisijeni yekukwegura yePolymer inonyanya kuwanikwa nekuwedzera muAntioxidants, uye maviri anoshandiswa mukusanganiswa, ayo ane synergistic maitiro uye anotakura anti-thermal oxygen okisijeni yekukwezva.
- Michina yekuita yechiitiko chekutanga antioxidants
Iyo huru diaxidant inogona kuita nemahara radicals rimacals uye bvisa kukura kwehydropexeroxides Iyo chaiyo nzira yekuita iri seinotevera:
Hydrogen vanopa, sekondari mashiripiti uye vakatadzisa phenoil antioxidants vane-hydrogen maAtoms kune ma radicals, saka kuti radicals inogadzira radical kana hydropereroxides.
Mahara Misungo Yemahara, Benzoquinone Antioxidants anoita nemahara radicals kuti aumbe radical yemahara yemahara.
Electron anopa, Tertiary Amine antioxicidants anopa magetsi ekutora radicals, vachiita kuti vafambe-zvigadzirisi zvigadziriso zvakanaka, kugumisa auto-oxidation maitiro.
Antiolary antioxidants inogona kushandiswa yega, asi shandira zviri nani neyechipiri antioxidants.
- Michina yekuita yeaxixidia diaxidants
Auxiliary antioxidants inogona kuora hydropereroxides yakagadzirwa neyekutanga antioxidant iyo ichiri kuita chimwe chiitiko, kuitira kuti vasatangezve otomatiki oxidation maitiro.
Mukuwedzera, auxiliary antioxidants inogona inhibit uye kunonoka kuumbwa kwemahara radical panguva yekutanga maitiro, uye kupfuudza simbi ion dzinosara muPolymer. Auxiliary antioxidants yakadai sePhosph Esters uye organic Sulffides ndeye hydropereroxide inodonha amiririri.
- Kusarudzwa kweAsioxidants
Kune marudzi mazhinji eAntioxidants, uye pfungwa dzinotevera dzinofanira kutariswa kana uchisarudza.

(2.
.! Nekudaro, ichachinja ruvara panguva yekugadzirisa uye kusvibisa chigadzirwa, uye kufukurwa kwakakura, saka hazviwanzo kushandiswa muzvinyorwa zvePolymer izvo zvinoda hutsanana.
. Zvese zviri pamusoro zvichakanganisa antioxidant mhedzisiro.
. Volattile zvinoreva nezvezvimwe zvigadzirwa zvekufunga nezve antioxidants kupukunyuka zvigadzirwa pakupukunyuka, uye kumusoro kwenzvimbo hurukuro uye yakakura huremu, kujairika kweAsiaxidants idiki.
- Kusarudzwa kweiyo primary antioxidants
TINOGONESA PHENOLL YEMAHARA ASIOXIDant inonyanya kushandiswa muPolymers nekuti haina kusvibisa chigadzirwa, iri pedyo ne chena, isina chepfu kana yakaderera. Iyo yekuwedzera huwandu hwe04 Dzimwe nguva inogona kushandiswa chete mune yakasviba mapolymer zvigadzirwa. Kuwedzerwa kweSynergistic kwemhando dzakasiyana dzeAntioxidants kune zvirinani pane imwe chete yekuwedzera, yakadai sekutadzisa phenol / yakadzivisa phenol kana kudzivisa ambine / kutadzisa phenol kusanganisa.
- Kusarudzwa kweAuxiliary Antioxidants
Pehosph ane maitiro akanaka eSynergistic neyenyanzvi huru, uye ine mwero weAndiyoxidant, kupokana nekupokana, kusarudzika kwemvura kurwisa kwemvura, asi kunogona kusarudza mhando ichangobva kugadziriswa yemvura. Kushandiswa kweSulfa-kune Inosimudzirwa AbixidAlary Auxicialary haina kuwanda semaFosheni, uye zviri nyore kuburitsa kusvibiswa kwekusvibiswa kana kusanganisa nezvimwe zvinowedzera, uye zvine chekuita neHars light stabilizers.
- Synergistic mhedzisiro yePrimary neAuxiliary Antioxidants
Auxiliary Asixidants inofanira kuwedzerwa muSyny yeAntioxidant yekuve neAndiyoxidant Eprioxidant Epridant, uye yekuwedzera kwayo yega haina antioxidant. Mhando dzekubatanidza dzeAntioxidants dzinotadzisa phenol / thioether, phosphite / thioeth / etc. Iyo huru antioxidant ndeye phenolic
