faahfaahinta alaabta
DSTDP Budada DSTDP Pastille Magaca Kiimikada: Distearyl thiodipropionate Kiimikada: S(CH2CH2COOC18H37)2 Miisaanka unugyada: 683.18 CAS Lambarka Aan biyo ku milmin, ku milmin benzene iyo toluene. La mid ah Antioxidant DSTDP, Irganox PS 802, Cyanox Stdp 3,3-Thiodipropionic acid di-n-octadecyl ester Distearyl 3,3-thiodipropionate Antioxidant DSTDP Distearyl thiodipropionate Antioxidant-STDP 3,3'-Thiodipropionate Antioxidant-STDP 3,3'-Thiodipropionate. muuqalka 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 mabda'a ee soo socda si aad u doorato: 1. Xasiloonida Inta lagu jiro habka wax soo saarka, antioxidant-ku waa inuu ahaado mid xasiloon, oo aan si sahlan loo beddelin, aan midab lahayn (ama aan midab lahayn), aan la jajabin, aan la falcelinin daroogooyinka kale ee kiimikada, oo aan la falcelinin daroogooyinka kale ee kiimikada inta lagu jiro deegaanka isticmaalka iyo habka heerkulka sare. Walxaha kale ee dusha sare waa la isweydaarsadaa oo ma daxaleeyaan qalabka wax soo saarka, iwm. Unugyada Antioxidant waxaa la dejiyaa inta u dhaxaysa molecules polymer inta lagu jiro daaweynta. 3. Tahriibka Dareen-celinta oksaydhka ee badeecadaha badankoodu waxay inta badan ku dhacdaa lakabka-gacmeedka, kaas oo u baahan in si joogto ah loogu wareejiyo antioxidants 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 farqiga u dhexeeya barta dhalaalaysa ee antioxidant iyo kala duwanaansho dhalaalidda ee walxaha processing aad u weyn, ifafaale ka mid ah faleebo anti-oxidant ama fur anti-oxidant ayaa dhacaya, taasoo keentay in aan sinnayn qaybinta antioxidant 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 inta aan la isticmaalin. 5. Nabadgelyadu waa inay jirtaa shaqo macmal ah oo ku jirta habka wax-soo-saarka, markaa antioxidant-ku waa inuu noqdaa mid aan sun ahayn ama aan sun ahayn, aan boodh lahayn ama boodh yar, mana yeelan doono waxyeello waxyeello u leh jidhka bini'aadamka marka la farsameynayo ama la isticmaalayo, oo aan wasakhayn deegaanka ku xeeran. Wax dhib ah uma soo gaadho 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.
