Makina azopanga ndi kapangidwe ka ma antioxir othandizira ku matexial oxygen ukalamba

Kukalamba kwa oxygen kukalamba kwa polymer kumatheka powonjezera ma antioxidants, omwe amatha kugawidwa ndi magwiridwe antchito, ndipo awiriwa amagwiritsidwa ntchito kuphatikiza, omwe ali ndi vuto la okosijeni ambiri.

• Makina ochita ma antioxidants antioxidants

Antioxidad wamkulu akhoza kuchita ndi ufulu waulere Ruble Rudical Ruble Ruble Ruble Ridical, amasintha kuti akule mwaulere, kutentha ndi kuyatsa, ndikukwaniritsa cholinga choteteza poyipitsa polymer. Njira yodziwikiratu ili motere:

Opereka hydrogen, achiwiri a arrylamines ndipo amalepheretsa ma antioxic phenoxantrants ali ndi ma atomu a hydrogen kuti azikhala ndi ma radicals okhazikika kapena hydropheroidedides.

Misampha yaulere ya Benzoququinone antioxinonts imakhudzana ndi ma radicals aulere kuti apange ma radical okhazikika.

Wopereka electron, tertive Antioxidants amapereka ma elekitironi kuti agwire zowala, zomwe zimapangitsa kuti azichita zinthu zochepa zowononga, zothetsa zauto.

Antioxidants ikuluikulu imatha kugwiritsidwa ntchito yokha, koma imagwira bwino ntchito ndi ma antioxaxaxidals.

• Makina a machitidwe a antiilimary antioxidants

Antioxirtory antioxidants imatha kuwola hydroprorox yopangidwa ndi antioxidant antiaxidant yomwe imagwirabe ntchito, kotero kuti sayambitsanso maxidation omwe amagwira.

Kuphatikiza apo, manyorlial antioxidants amatha kulepheretsa ndikuchepetsa mapangidwe a radicals aulere panthawi yoyambitsa, ndikupereka chithunzi cha zitsulo zotsalira mu polymer. Antialiatiatestates orioxitis monga esphote ests ndi sulfides organic ndi hydroprodexide kuwola.

• Kusankhidwa kwa Antioxidants

Pali mitundu yambiri ya antioxidants, ndipo mfundo zotsatirazi ziyenera kukhala ndi chidwi posankha.

.

(2) Kuchitapo kanthu

. Komabe, imasintha mtundu pokonzanso ndi kuipitsa malondawo, ndipo pozindikira ndizazazikulu, kotero sizigwiritsidwa ntchito popanga zinthu polymer zomwe zimafuna ukhondo.

. Zonsezi pamwambapa zidzakhudza zotsatira za antioxidant.

. Volalen amatanthauza zinthu za polymen zomwe zimakhala ndi antioxidarantrants atatenthedwa, ndipo ndikukweza maziko ndi zazikulu zochulukitsa kwa antioxaxaxtants.

• Kusankhidwa kwa Antioxidants

Kulepheretsa phenolic Grourcidant antioxidant kumagwiritsidwa ntchito kwambiri pamakapu chifukwa sikuyipitsa malondawo, ali pafupi ndi zoponyera, zopanda zoopsa kapena zotsika. Kuphatikiza kwa 0,4% ~ 0.45% Kulepheretsa Antioxidant Antioxidant Ali ndi Antioxidant Yabwino, koma ndizosavuta kupangira mitundu ndi zoopsa za polymers. Nthawi zina imatha kugwiritsidwa ntchito popanga zinthu zakuda polymer. Kuwiritsa kosiyanasiyana kwa mitundu yosiyanasiyana ya Antioxidants ali bwino kuposa kuphatikiza kulikonse, monga kulepheretsa phenol / kulepheretsa kuphatikiza kwa pheno / cholepheretsa phenol.

• Kusankhidwa kwa anioxirtory antioxidants

Phosphite ali ndi vuto lalikulu ndi antioxidant yayikulu, ndipo ali ndi digiri ya antioxidant, kukana kutentha, kukana kwanyengo ndi njira zabwino, zonyansa ndi madzi osagwirizana ndi madzi. Kugwiritsa ntchito sulufule-okhala ndi ma antioxarlants ogwiritsa ntchito sikuti ndi ma rosphites, ndipo ndizosavuta kutulutsa kuwonongeka kwa sulfure mukaphatikizidwa ndi zowonjezera zina, ndipo kumapangitsa kuti hals ikhale yokhazikika.

• Zotsatira za Synergist za ma antioxil antioxidants

Antioxirtory antioxidants ayenera kuwonjezeredwa mu synergy ndi antioxidant yokhala ndi antioxidant yokhala ndi antioxidant kuti achititse kanthu, ndipo kubwereza kwake koyambirira kowonjezeredwa, ndipo kuwonjezera kwake kokha sikunachite antioxidant. Mitundu yosiyanasiyana ya antioxited ma antioxited / Thioether, phosphote / kulepheretsa phenolic 1010, ndi seweroli.
