    I-DSTDP Powder DSTDP Pastille Igama leKhemikhali: I-Distearyl thiodipropionate Ifomula ye-Chemical: S(CH2CH2COOC18H37)2 Isisindo se-molecular: 683.18 CAS No.: 693-36-7 Incazelo yezakhiwo: Lo mkhiqizo uyimpushana emhlophe e-crystalline noma ama-granules. Ayincibiliki emanzini, ayincibiliki ku-benzene ne-toluene. I-Synonym 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 3propionate Antioxidant-STDP 3propidecyl 3propionate Ukubukeka: I-White crystalline powder/ Pastilles Ash:Max.0.10% Iphuzu elincibilikayo：63.5-68.5℃ Isicelo I-Antioxidant DSTDP iyi-antioxidant ewusizo enhle futhi isetshenziswa kabanzi ku-polypropylene, i-polyethylene, i-polyvinyl chloride, i-ABS namafutha okugcoba. Inoncibilika kakhulu kanye nokuguquguquka okuphansi. I-DSTDP ingasetshenziswa futhi ekuhlanganisweni nama-phenolic Antioxidants kanye ne-ultraviolet absorbers ukukhiqiza umphumela we-synergistic. Ngokombono wokusetshenziswa kwezimboni, ungakwazi ngokuyisisekelo ukubhekisela ezimisweni ezinhlanu ezilandelayo ongakhetha kuzo: 1. Ukuzinza Phakathi nenqubo yokukhiqiza, i-antioxidant kufanele ihlale izinzile, ingaguquguquki kalula, ingaguquki (noma ingabi nombala), ingaboli, ingaphenduli nezinye izithasiselo zamakhemikhali, futhi ingaphenduli nezinye izithasiselo zamakhemikhali ngesikhathi sokusetshenziswa kwemvelo kanye nokucubungula izinga lokushisa eliphezulu. Ezinye izinto ezingaphezulu ziyashintshaniswa futhi ngeke zigceme imishini yokukhiqiza, njll. 2. Ukuhambisana Ama-macromolecules ama-polymer epulasitiki ngokuvamile awawona ama-polar, kuyilapho ama-molecule e-antioxidant enamazinga ahlukene e-polarity, futhi kokubili kunokuhambisana okuncane. Ama-molecule e-Antioxidant ahlaliswa phakathi kwama-polymer molecule ngesikhathi sokwelashwa. 3. Ukufuduka Ukusabela kwe-oxidation yemikhiqizo eminingi ikakhulukazi kwenzeka ongqimbeni olungajulile, oludinga ukudluliselwa okuqhubekayo kwama-antioxidants kusuka ngaphakathi komkhiqizo kuya phezulu ukuze kusebenze. Kodwa-ke, uma izinga lokudlulisa lishesha kakhulu, kulula ukuguquguquka endaweni bese ulahleka. Lokhu kulahlekelwa akunakugwenywa, kodwa singaqala ngesakhiwo sefomula ukuze sinciphise ukulahlekelwa. 4. Ukucutshungulwa Uma umehluko phakathi kwephoyinti lokuncibilika le-antioxidant kanye nebanga lokuncibilika lempahla yokucubungula inkulu kakhulu, isenzakalo se-anti-oxidant drift noma isikulufu se-anti-oxidant sizokwenzeka, okuzoholela ekusabalaliseni okungalingani kwe-antioxidant emkhiqizweni. Ngakho-ke, lapho iphoyinti lokuncibilika le-antioxidant liphansi kunezinga lokushisa lokucubungula impahla elingaphezu kuka-100 °C, i-antioxidant kufanele yenziwe i-masterbatch yokuhlushwa okuthile, bese ixutshwa nenhlaka ngaphambi kokusetshenziswa. 5. Ukuphepha Kufanele kube nomsebenzi wokwenziwa ohlelweni lokukhiqiza, ngakho-ke i-antioxidant kufanele ingabi nobuthi noma ingabi nobuthi obuncane, ingabi nothuli noma ibe nothuli oluncane, futhi ngeke ibe nemiphumela elimazayo emzimbeni womuntu ngesikhathi sokucubungula noma ukusetshenziswa, futhi ingabi nokungcoliswa kwemvelo ezungezile. Akukho monakalo ezilwaneni nasezitshalweni. Ama-Antioxidants ayigatsha elibalulekile lama-polymer stabilizers. Enqubweni yokucubungula impahla, kufanele kubhekwe kakhulu isikhathi, uhlobo kanye nenani lama-antioxidants angeziwe ukugwema ukwehluleka ngenxa yezimo zemvelo.
