Ekusetyenzisweni nasekusetyenzisweni kwexesha elide kweeplastiki, ukuguga kwe-oxidative yeyona nto iphambili ethintela ubomi kunye nokusebenza kweemveliso—ukulungiswa kwe-high temperature kukhokelela ngokulula ekonakaleni kwe-resin, kwaye iindawo zangaphandle okanye ezishushu kakhulu zinokubangela iingxaki ezifana nokuqhekeka, ukuqhekeka, kunye nokuwohloka kombala. Ii-antioxidants, "njengabagcini bokuguga" beeplastiki, zinokuthintela ukusabela kwe-oxidation chain kumthombo wayo. I-Antioxidant 1010, njengemveliso yokulinganisa phakathi kwee-antioxidants ze-phenolic, iye yaba sisongezelelo esikhethwayo kwiiplastiki ze-PE, PP, ABS, kunye nobunjineli ngenxa yokusebenza kwayo okuphezulu, ububanzi bayo, kunye neempawu ezinobuhlobo nokusingqongileyo. Eli nqaku liza kuhlalutya ngokupheleleyo i-Antioxidant 1010 ukusuka kubukhulu be-essence yemveliso, iingenelo eziphambili, usetyenziso lweshishini, kunye nokukhetha kwesayensi, libonelela ngereferensi yobungcali kumashishini ukukhetha ngokuchanekileyo izixhobo kunye nokuphucula ukhuphiswano lwemveliso.
I. UkuqondaI-Antioxidant 1010: Kutheni le nto iye yaba luphawu lokulinganisa ishishini?
Igama lekhemikhali le-Antioxidant 1010 yi-pentaerythritol tetrakis(β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid), eliphakathi kwe-antioxidants eziphambili ze-phenolic ezinobunzima obuphezulu. Ulwakhiwo lwayo olukhethekileyo lwe-molecular luyinika iipropati ezintle ze-antioxidant kunye nokuhambelana kwayo, kwaye yaziwa ngokuba "ngukumkani wee-antioxidants".
1. Indlela Ephambili Yokusebenza: Ukuthintela Ukwaluphala Okubangelwa Yi-Oxidative kwiNtsongo Yako
Eyona nto iphambili ekugugeni kweplastiki yi-free radical chain reaction. I-Antioxidant 1010 ivimba inkqubo yokusabela ngemisebenzi emibini ephambili: okokuqala, ibamba ngokukhutheleyo ii-free radicals eziveliswa ngexesha le-oxidation, yenza isakhiwo esizinzileyo se-molecular, kwaye iphelisa ukudluliselwa kunye nokwanda kwee-free radicals; okwesibini, ibopha ii-trace metal ions kwiiplastiki nge-chelation, inciphisa i-catalytic acceleration effect yee-metal ions kwi-oxidation reaction. Olu khuselo lubini luqinisekisa i-anti-aging effect.
2. Iingenelo zeMveliso eziPhambili: Iimpawu eziphambili ezilungelelaniswe neemeko ezininzi
