Isicelo
I-Antioxidant DSTDP iyi-antioxidant ewusizo enhle futhi isetshenziswa kakhulu 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 nezinto zokumunca i-ultraviolet ukuze kukhiqizwe umphumela we-synergistic.
Ngokombono wokusetshenziswa kwezimboni, ungabheka ngokuyisisekelo izimiso ezinhlanu ezilandelayo ongakhetha kuzo:
1. Ukuzinza
Phakathi nenqubo yokukhiqiza, i-antioxidant kufanele ihlale izinzile, ingaguquguquki kalula, ingashintshiwe (noma ingabi nombala), ingaboli, ingaphenduli nezinye izithasiselo zamakhemikhali, futhi ingaphenduli nezinye izithasiselo zamakhemikhali ngesikhathi sokusebenzisa imvelo kanye nokucubungula izinga lokushisa eliphezulu.Ezinye izinto ezingaphezulu ziyashintshaniswa futhi ngeke zigceme imishini yokukhiqiza, njll.
2. Ukuvumelana
Ama-macromolecules ama-polymer epulasitiki ngokuvamile awawona ama-polar, kuyilapho ama-molecule e-antioxidant enamazinga ahlukene e-polarity, futhi amabili awahambisani kahle.Ama-molecule e-Antioxidant ahlaliswa phakathi kwama-polymer molecule ngesikhathi sokwelashwa.
3. Ukufuduka
Ukusabela kwe-oxidation yemikhiqizo eminingi kwenzeka ikakhulukazi 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, into eyenzekayo ye-anti-oxidant drift noma isikulufu se-anti-oxidant sizokwenzeka, okuholela 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. Ezokuphepha
Kumele kube nomsebenzi wokwenziwa enqubweni yokukhiqiza, ngakho-ke i-antioxidant kufanele ingabi nobuthi noma ingabi nobuthi obuphansi, ingabi nothuli noma ibe nothuli oluncane, futhi ngeke ibe nemiphumela elimazayo emzimbeni womuntu ngesikhathi icutshungulwa noma isetshenziswa, futhi ingabi nokungcola. endaweni 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.
