    I-DSTDP Powder DSTDP Pastille Igama leKhemikhali: Distearyl thiodipropionate Ifomula yeMichiza: S(CH2CH2COOC18H37)2 Ubunzima bemolekyuli: 683.18 Inombolo ye-CAS: 693-36-7 Inkcazo yeepropati: Le mveliso imhlophe i-crystalline powder okanye i-granules. Ayinyibiliki emanzini, i-soluble kwi-benzene kunye ne-toluene. I-Synonym Antioxidant DSTDP, i-Irganox PS 802, i-Cyanox Stdp 3,3-Thiodipropionic acid di-n-octadecyl ester Distearyl 3,3-thiodipropionate Antioxidant DSTDP Distearyl thiodipropionate Antioxidant-STDP3-STDP 3, 3,3-thiodipropionate Antioxidant DSTDP Imbonakalo:Ikristale emhlophe ewumgubo/ iPastilles Uthuthu:Max.0.10% Indawo yokunyibilika:63.5-68.5℃ Application Antioxidant DSTDP luncedo oluhle lwe-antioxidant kwaye lusetyenziswa ngokubanzi kwi-polypropylene, i-polyethylene, i-polyvinyl chloride, i-ABS kunye neoli yokuthambisa. Inokunyibilika okuphezulu kunye nokuguquguquka okuphantsi. I-DSTDP ingasetyenziselwa ngokudibanisa ne-phenolic antioxidants kunye ne-ultraviolet absorbers ukuvelisa umphumo we-synergistic. Ngokombono wokusetyenziswa kwezoshishino, unokubhekisela ngokusisiseko kule migaqo mihlanu ilandelayo yokukhetha: 1. Uzinzo Ngexesha lenkqubo yokuvelisa, i-antioxidant kufuneka ihlale izinzile, ingabi lula, ingabonakali (okanye ingabi nombala), ingaboli, ingaphenduli kunye nezinye izongezo zekhemikhali, kwaye ingaphenduli kunye nezinye izongezo zekhemikhali ngexesha lendawo yokusetyenziswa kunye nokushisa okuphezulu. Ezinye izinto eziphezu komhlaba ziyatshintshwa kwaye aziyi kugqwala izixhobo zokuvelisa, njl. njl. 2. Ukuhambelana I-macromolecules ye-polymers zeplastiki ngokuqhelekileyo ayinayo i-polar, ngelixa i-molecule ye-antioxidants ine-degrees ezahlukeneyo ze-polarity, kwaye ezi zimbini zinokuhambelana kakubi. Iimolekyuli ze-Antioxidant zihlaliswa phakathi kweemolekyuli zepolymer ngexesha lokunyanga. 3. Ukufuduka Ukusabela kwe-oxidation yeemveliso ezininzi kwenzeka ikakhulu kumaleko angekho nzulu, efuna ukuhanjiswa okuqhubekayo kwe-antioxidants ukusuka ngaphakathi kwemveliso ukuya kumphezulu ukuze usebenze. Nangona kunjalo, ukuba izinga lokudluliselwa likhawuleza kakhulu, kulula ukuguquguquka kwimo engqongileyo kwaye ilahleke. Le lahleko ayinakuthintelwa, kodwa sinokuqala ngoyilo lwefomula ukunciphisa ilahleko. 4. Ukucubungula Ukuba umehluko phakathi kwendawo yokuncibilika kwe-antioxidant kunye noluhlu lokunyibilika kwezinto zokucubungula lukhulu kakhulu, i-phenomenon ye-anti-oxidant drift okanye i-screw anti-oxidant iya kwenzeka, okubangela ukusabalalisa okungafaniyo kwe-antioxidant kwimveliso. Ke ngoko, xa iqondo lokunyibilika le-antioxidant lisezantsi kunobushushu bokulungisa izinto ezingaphezulu kwe-100 °C, i-antioxidant kufuneka yenziwe ibe yi-masterbatch yoxinaniso oluthile, emva koko ixutywe nentlaka phambi kokusetyenziswa. 5. Ukhuseleko Kufuneka kubekho umsebenzi owenziweyo kwinkqubo yokuvelisa, ngoko ke i-antioxidant kufuneka ingabi netyhefu okanye i-low-toxic, ingenalo uthuli okanye uthuli oluphantsi, kwaye ayiyi kuba nemiphumo emibi emzimbeni womntu ngexesha lokucubungula okanye ukusetyenziswa, kwaye akukho ngcoliseko kwindawo engqongileyo. Akukho bungozi kwizilwanyana nakwizityalo. I-Antioxidants lisebe elibalulekileyo le-polymer stabilizers. Kwinkqubo yokulungiswa kwezinto, ingqwalasela engaphezulu kufuneka ihlawulwe kwixesha, uhlobo kunye nesixa se-antioxidants eyongeziweyo ukuphepha ukusilela ngenxa yezinto ezisingqongileyo.
