Lapho oxhumana nabo bendabuko be-penonic antioxidant nge-nitrogen nogesi emoyeni, kukhiqiza isakhiwo se-quinone. Isakhiwo se-qinone siyimbangela yezimpande zokuphuzi nokutholwa.
I-Phosfute Antioxidant nayo isetshenziswa kabanzi njenge-antioxidant enhle kakhulu. Kodwa-ke, ngokuthuthuka okuqhubekayo kwamazinga okuvikela ezemvelo e-EU, izidingo ze-antioxidant phosphite ziba ngaphezulu nangaphezulu. I-Phosphite Antioxidant idinga ukuba nemvelo ngokwemvelo, okungeyona eye-anobuthi, i-non-phenolic, i-hydrolysis, futhi yemelana nezinga lokushisa eliphakeme.
I-antioxidant ye-phosphite auxiliary ingenye yezithasiselo ezisebenzayo kakhulu ze-polymer ezikhuthazayo ngawo-1990. Eminyakeni eyishumi, izinhlobo ezintsha zesakhiwo zivela ngokungapheli, kepha ngesakhiwo sazo samakhemikhali, singathola ukuthi isakhiwo esisha se-phosfite siqukethe indandatho emnandi kakhulu, futhi ikakhulukazi yiPentaerythritol Diphhosfite Ship Shrivilayo kanye ne-Bisphenol Phosphite Ester Isakhiwo. Kusho ukuthi i-phosphate ester antioxidant Technology Development kufanele igxile ezicini ezimbili: indlela yokuthuthukisa ukuqina kwemishini nokuthi ungawuthuthukisa kanjani ukuqina kwe-hydrolytic.
I-antioxidant yethu engeyona eye-penolic-phenolic ne -333 ne-AN340, ayiqukethe i-phenolic sakhiwo, ngakho-ke ingagwema ngempumelelo inkinga ephuzi ebangelwa yi-quininone sakhiwo. Amazinga okushisa asebenza angaba ngaphezulu kwe-180 ℃, futhi kusetshenziswe ePu, PVC nakwezinye izinkambu ngamakhasimende amaningi kwa naphesheya kwezilwandle.
Phakathi kwazo, u-AN333 ukhombisile ukuthi wenza kahle ezintweni zokwakha ama-pu, ngokumelana kahle nomoya ophuzi nokuphikiswa okuhle kwe-hydrolysis. Kuyinto enhle kunazo zonke ye-Joyi Chemical J333E.
Ngaphandle kwe-antioxidants engeyona eye-phenol, sinikeza nezinye izengezo ezisetshenziswa kuhlelo lokusebenza lwe-pu. Ngezansi kwemikhiqizo kungokukhetha kwakho:
| Ukuhlela ngohlobo oluthile | Umphumela | Umkhoga | Uhlobo lwe-Counter |
| UV absorber | I-Yihoo UV1 | 57834-33-0 | |
| I-Yihoo UV571 | 23328-53-53-2 | Tinuvin 571 | |
| I-yihoo uv b75 | Xubanisa | Tinuvin b75 | |
| I-antioxidant | I-Yihoo AN333 | 77745-66-5 | JP333E |
| I-Yihooo ANN340 | / | ||
| I-Flame Retardant | I-Yihoo fr950 | / |
