Ifu ya DSTDP DSTDP Pastille Izina ryimiti: Distearyl thiodipropionate Imiti yimiti: S (CH2CH2COOC18H37) 2 Uburemere bwa molekuline: 683.18 CAS No. Kudashonga mumazi, gushonga muri benzene na toluene. Synonym Antioxidant DSTDP, Irganox PS 802, Cyanox Stdp 3,3-Thiodipropionic aside di-n-octadecyl ester Distearyl 3,3-thiodipropionate Antioxidant DSTDP Distearyl thiodipropionate Antioxidant-STDP 3,3'-Thiodipropionic aside Pastilles Ash ： Max.0.10% Gushonga point 63.5-68.5 ℃ Gukoresha Antioxidant DSTDP ni antioxydants nziza ifasha kandi ikoreshwa cyane muri polypropilene, polyethylene, polyvinyl chloride, ABS hamwe namavuta yo gusiga. Ifite gushonga cyane no guhindagurika. DSTDP irashobora kandi gukoreshwa ifatanije na antioxydants ya fenolike na sisitemu ya ultraviolet kugirango itange umusaruro. Uhereye ku mikoreshereze y’inganda, urashobora ahanini kwifashisha amahame atanu akurikira kugirango uhitemo: 1. Guhagarara Mugihe cyibikorwa, umusaruro wa antioxydeant ugomba kuguma uhagaze neza, ntuhindurwe byoroshye, ntuhindurwe ibara (cyangwa udafite ibara), ntushobora kubora, ntukorwe nibindi byongeweho imiti mugihe cyo gukoresha ibidukikije no gutunganya ubushyuhe bwinshi. Ibindi bintu biri hejuru birahanahana kandi ntibishobora kwangiza ibikoresho byumusaruro, nibindi 2. Guhuza Makromolekula ya polymers ya plastike muri rusange ntabwo ari polar, mugihe molekile za antioxydants zifite impamyabumenyi zitandukanye za polarite, kandi byombi ntibishobora guhuza neza. Molekile ya Antioxydeant iba hagati ya molekile ya polymer mugihe cyo gukira. 3. Kwimuka Kwiyongera kwa okiside yibicuruzwa byinshi bibaho cyane cyane murwego ruto, bisaba ko hakomeza kwimurwa antioxydants kuva imbere mubicuruzwa kugeza hejuru kugirango bikore. Ariko, niba igipimo cyo kwimura cyihuta cyane, biroroshye guhindagurika mubidukikije no kubura. Iki gihombo ntigishobora kwirindwa, ariko turashobora gutangirana nigishushanyo mbonera kugirango tugabanye igihombo. 4. Kubwibyo, mugihe ingingo yo gushonga ya antioxydeant iri munsi yubushyuhe bwo gutunganya ibintu hejuru ya 100 ° C, antioxydeant igomba gukorwa muburyo bukomeye bwibintu runaka, hanyuma ikavangwa na resin mbere yo kuyikoresha. 5. Umutekano Hagomba kubaho imirimo yubukorikori mugikorwa cyo kubyaza umusaruro, bityo antioxydeant igomba kuba idafite uburozi cyangwa uburozi buke, butagira umukungugu cyangwa umukungugu muke, kandi ntibizagira ingaruka mbi kumubiri wumuntu mugihe cyo kuyitunganya cyangwa kuyikoresha, kandi nta mwanda wangiza ibidukikije. Nta ngaruka mbi ku nyamaswa n'ibimera. Antioxydants ni ishami ryingenzi rya polymer stabilisateur. Mugihe cyo gutunganya ibikoresho, hagomba kwitabwaho cyane mugihe, ubwoko nubwinshi bwa antioxydants yongeweho kugirango wirinde kunanirwa bitewe nibidukikije.
