Kugwiritsa ntchito
Antioxidant DSTDP ndi yabwino yothandiza antioxidant ndipo imagwiritsidwa ntchito kwambiri mu polypropylene, polyethylene, polyvinyl chloride, ABS ndi mafuta opaka mafuta.Ili ndi kusungunuka kwakukulu komanso kutsika kwamphamvu.
DSTDP itha kugwiritsidwanso ntchito limodzi ndi phenolic antioxidants ndi ultraviolet absorbers kuti apange synergistic effect.
Kutengera momwe mungagwiritsire ntchito mafakitale, mutha kulozera ku mfundo zisanu zotsatirazi zomwe mungasankhe:
1. Kukhazikika
Panthawi yopanga, antioxidant iyenera kukhala yokhazikika, yosasunthika mosavuta, yosasunthika (kapena yosakhala yakuda), osavunda, osachita ndi zina zowonjezera mankhwala, komanso osachita ndi zina zowonjezera mankhwala panthawi yogwiritsira ntchito chilengedwe komanso kutentha kwambiri.Zinthu zina pamtunda zimasinthidwa ndipo sizingawononge zida zopangira, ndi zina.
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 samagwirizana bwino.Mamolekyu a Antioxidant amasungidwa pakati pa mamolekyu a polima panthawi yochiritsa.
3. Kusamuka
Zomwe makutidwe ndi okosijeni azinthu zambiri zimachitika mosazama kwambiri, zomwe zimafunikira kusamutsa kosalekeza kwa ma antioxidants kuchokera mkati mwa mankhwala kupita kumtunda kuti agwire 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 kuposa 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 yokumba popanga, kotero kuti antioxidant sayenera kukhala poizoni kapena otsika poizoni, wopanda fumbi kapena otsika fumbi, ndipo sadzakhala ndi zotsatira zoipa pa thupi la munthu pokonza kapena ntchito, ndipo palibe kuipitsa. ku chilengedwe chozungulira.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.
