DSTDP Powder DSTDP Pastille Dzina la mankhwala: Distearyl thiodipropionate Chemical formula: S(CH2CH2COOC18H37)2 Kulemera kwa maselo: 683.18 CAS No.: 693-36-7 Kufotokozera za katundu: Mankhwalawa ndi ufa woyera wa crystalline kapena granules. Insoluble m'madzi, sungunuka mu benzene ndi toluene. 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 3, 3-thiodipropionate Antioxidant DSTDP Maonekedwe: White crystalline ufa / Pastilles Phulusa: Max.0.10% Malo osungunuka: 63.5-68.5 ℃ Ntchito Antioxidant DSTDP ndi wabwino wothandiza antioxidant ndipo chimagwiritsidwa ntchito polypropylene, polyethylene, polyvinyl kolorayidi, ABS ndi mafuta mafuta. Ili ndi kusungunuka kwakukulu komanso kutsika kwamphamvu. DSTDP itha kugwiritsidwanso ntchito limodzi ndi phenolic antioxidants ndi ultraviolet absorbers kuti apange synergistic effect. Kuchokera pamaganizo a ntchito ya mafakitale, mukhoza kwenikweni kutchula mfundo zisanu zotsatirazi zomwe mungasankhe: 1. Kukhazikika Panthawi yopangira, antioxidant iyenera kukhala yokhazikika, yosasunthika mosavuta, yosasunthika (kapena yosakhala yamitundu), osawonongeka, osakhudzidwa ndi zina zowonjezera mankhwala, komanso osachitapo kanthu ndi zina zowonjezera mankhwala pa nthawi yogwiritsira ntchito chilengedwe ndi kutentha kwapamwamba. Zinthu zina padziko lapansi zimasinthidwa ndipo sizingawononge zida zopangira, etc. 2. Kugwirizana Ma macromolecules a ma polima apulasitiki nthawi zambiri sakhala a polar, pomwe mamolekyu a antioxidants amakhala ndi magawo osiyanasiyana a polarity, ndipo awiriwa ali ndi vuto losagwirizana. Mamolekyu a Antioxidant amasungidwa pakati pa mamolekyu a polima panthawi yochiritsa. 3. Kusamuka Zomwe makutidwe ndi okosijeni azinthu zambiri zimachitikira m'malo osaya, zomwe zimafunikira kusamutsidwa kosalekeza kwa ma antioxidants kuchokera mkati mwa mankhwalawa kupita kumtunda kukagwira ntchito. Komabe, ngati kutengerako kuchuluka kwachangu, ndikosavuta kusokoneza chilengedwe ndikutayika. Kutayika kumeneku sikungapeweke, koma titha kuyamba ndi kupanga ma formula kuti tichepetse kutaya. 4. Processability Ngati kusiyana pakati pa malo osungunuka a antioxidant ndi kusungunuka kwa zinthu zowonongeka ndi zazikulu kwambiri, zochitika za anti-oxidant drift kapena anti-oxidant screw zidzachitika, zomwe zimapangitsa kuti pakhale kugawidwa kosiyana kwa antioxidant mu mankhwala. Choncho, pamene malo osungunuka a antioxidant ndi otsika kusiyana ndi kutentha kwa zinthu zopangira zinthu zopitirira 100 ° C, antioxidant iyenera kupangidwa kukhala masterbatch ya ndende inayake, ndiyeno imasakanizidwa ndi utomoni musanagwiritse ntchito. 5. Chitetezo Payenera kukhala ntchito yopangira ntchito popanga, kotero kuti antioxidant iyenera kukhala yopanda poizoni kapena yochepa, yopanda fumbi kapena fumbi lochepa, ndipo sichidzakhala ndi zotsatira zovulaza pa thupi la munthu panthawi yokonza kapena kugwiritsa ntchito, ndipo palibe kuipitsa malo ozungulira. Palibe vuto kwa nyama ndi zomera. Antioxidants ndi nthambi yofunika ya polima stabilizers. Pokonza zinthu, chidwi chochulukirapo chiyenera kuperekedwa ku nthawi, mtundu ndi kuchuluka kwa ma antioxidants omwe amawonjezeredwa kuti apewe kulephera chifukwa cha chilengedwe.
