Nigute wahitamo Antioxydant ikwiye?

Uburyo bwoHitamoiAbikwiyeAntiogisijeni？

Guhitamo antioxydant ikwiye ni intambwe y'ingenzi yo kunoza kuramba, imiterere n'imikorere ya polymer. Ibi bisaba gusuzuma neza ibintu byinshi nko imiterere ya polymer ubwayo, imiterere yo kuyitunganya, ibidukikije bikoreshwa nyuma y'ikoreshwa ryayo n'amategeko agenga kurengera ibidukikije.

Polyolefini(nka polyethylene na polypropylene) bishobora kwangirika mu bushyuhe, bigasaba antioxydants z'ibanze (nka phenols) gufata radicals yigenga hamwe na antioxydants zifasha (nka phosphites) kugira ngo zibore hydroperoxide.

PVCKwangirika kw'ibintu bishingiye ahanini kuri iyonize, kandi ugereranije na polyolefins, abakora PVC ntibakeneye antioxydants nyinshi. Muri iki gihe, antioxydants zikoreshwa cyane kuri PVC zirimoAO1076, AO2246, n'ibindi.

Plastike z'ubwubatsi(PA, PC, PPS) muri rusange bitunganywa ku bushyuhe bwinshi kandi bisabaantioxydants zirinda ubushyuhekugira ngo hirindwe umuhondo no gutakaza imbaraga.

①Ku bijyanye n'uburyo bwo gutunganya ibihingwa mu bushyuhe bwinshi (>280 ℃), ni byiza guhitamo ubwoko bufite ubushyuhe buke kandi budashobora guhindagurika cyane.

②Kugira ngo umuntu agaragare hanze igihe kirekire, hakenewe uburyo bwo kurwanya imirasire y'izuba, nk'ibinyabutabire bya phenolic naUtwuma dufata imirasire ya UV.

③Witondere guhuza ibintu kandi wirinde imvura. Byongeye kandi, antioxydants za amine zifite uburinzi buke bw'amabara.

④Uruvange rw'ibinyabutabire by'ingenzi n'ibinyabutabire by'inyongera bishobora kongera cyane ingaruka zo kurwanya gusaza.

Muri make, gukoresha imiti irwanya okisidanti byonyine ntibihagije kugira ngo bihangane n’ibibazo bitandukanye, kandi guhuza inyongeramusaruro nyinshi ni amahitamo meza.
