Codsiga
Antioxidant DSTDP waa antioxidant caawiye oo wanaagsan waxaana si weyn loogu isticmaalaa polypropylene, polyetylen, chloride polyvinyl, ABS iyo saliida saliidda.Waxay leedahay dhalaalid sare iyo isbeddel hoose.
DSTDP sidoo kale waxaa loo isticmaali karaa in lagu daro phenolic antioxidants iyo ultraviolet absorbers si loo soo saaro saameyn isku dhafan.
Marka laga eego dhinaca isticmaalka warshadaha, waxaad asal ahaan tixraaci kartaa shanta qodob ee soo socda si aad u doorato:
1. Xasilooni
Inta lagu jiro habka wax-soo-saarka, antioxidant-ku waa inuu ahaado mid deggan, oo aan si fudud u kicin, aan midab lahayn (ama aan midab lahayn), aan la jajabin, aan la falgalin waxyaallaha kale ee kiimikooyinka, oo aan la falgalin waxyaallaha kale ee kiimikada inta lagu jiro deegaanka isticmaalka iyo habka heerkulka sare.Walxaha kale ee dusha sare waa la isweydaarsadaa oo ma daxaloobayaan qalabka wax soo saarka, iwm.
2. Waafaqid
Makromolecules ee polymers caag ah guud ahaan waa non-polar, halka molecules ee antioxidants ay leeyihiin heerar kala duwan oo polarity, iyo laba leeyihiin iswaafajin liidata.Unugyada Antioxidant waxaa la dejiyaa inta u dhaxaysa molecules polymer inta lagu jiro daaweynta.
3. Tahriibka
Dareen-celinta oksaydhka ee badeecadaha intooda badani waxay inta badan ku dhacaan lakabka gacmeed, kaas oo u baahan wareejinta joogtada ah ee antioxidants ee gudaha alaabta si ay u shaqeyso.Si kastaba ha ahaatee, haddii heerka wareejintu aad u degdego, way fududahay in la geliyo deegaanka oo la lumiyo.Khasaarahani waa mid aan laga fursan karin, laakiin waxaan ku bilaabi karnaa naqshadaynta caanaha si loo yareeyo khasaaraha.
4. Processability
Haddii faraqa u dhexeeya barta dhalaalka ee antioxidant-ka iyo kala duwanaanta dhalaalka ee walxaha farsamaynta uu aad u weyn yahay, waxaa dhacaya ifafaale ka mid ah qulqulka anti-oxidant ama furaha-anti-oxidant, taasoo keentay in aan sinnayn qaybinta antioxidant-ka ee alaabta.Sidaa darteed, marka barta dhalaalaysa ee antioxidant-ku ay ka hooseyso heerkulka wax-qabadka walxaha in ka badan 100 ° C, antioxidant-ka waa in laga dhigaa heer sare oo ka mid ah feejignaan gaar ah, ka dibna lagu qaso resin ka hor isticmaalka.
5. Amniga
Waa in uu jiro shaqo macmal ah oo ku jirta habka wax soo saarka, markaa antioxidant-ku waa in uu ahaado mid aan sun ahayn ama hooseeyo, boodh-free ama boodh yar, oo aan wax saameyn ah ku yeelan doonin jidhka bini'aadamka inta lagu jiro farsamaynta ama isticmaalka, oo aan wasakhayn. deegaanka ku xeeran.Wax dhib ah uma soo gaaro xoolaha iyo dhirta.
Antioxidants waa laan muhiim ah oo ka mid ah xasiliyayaasha polymer.Habka wax-soo-saarka walxaha, fiiro gaar ah waa in la bixiyaa waqtiga, nooca iyo qadarka antioxidants ee lagu daro si looga fogaado fashilka sababo la xiriira deegaanka.
