Impushana ye-latex ehlakazeka kabushaisengozini enkulu yokuhlaselwa ukushisa nomoya-mpilo, okuholela kuma-radicals angenawo umoya-mpilo amaningi kanye ne-hydrogen Chloroprene.Ii-latex powderkuholela ekubhujisweni kwe-polymer chain opening.Ngemuva kwempushana ye-latex, ukugqoka kancane kancane kuyaguga.Impushana ye-latex ehlakazeka kabusha inciphise ukugqama, i-delamination yendawo kanye nokushintsha kombala.Ukwengeza ama-antioxidants ku-latex powder kungavimbela ngokuphumelelayo ukuziphatha kokuguga kwe-oxidative yama-polymers.
Ukhiye wei-latex powder ehlakazeka kabushaihlanganisa i-Phosphite ester antioxidant kanye ne-thiolipid antioxidant.Indlela yokusebenza ye-latex powder ukuhlakaza i-ROOH, ukuze i-latex powder ikwazi ukwakha izingxenye ezizinzile.Inhlanganisela yama-antioxidant ayinhloko kanye ne-axiliary ingaba nomphumela othile we-synergistic, futhi ingahlakazwa ngokuqhubekayo ibe yi-latex powder ukuze kuzuzwe ukusebenza okungcono kwe-antioxidant.
Eminyakeni yamuva, ngokuqiniswa okukhulu nokujula kokuvikelwa kwemvelo kweI-RDPeShayina, impushana ye-latex ibeke ngokucacile izinga eliphezulu lokongiwa kwamandla kanye nemithethonqubo yokuvikela imvelo emkhakheni wezingubo zokugqoka.Umkhakha we-latex powder kanye nopende we-latex powder usuguquke kancane kancane waba yi-soluble yamanzi, okuqukethwe okuqinile okuphezulu, i-Solvation nezinye izici, futhi i-latex powder ithole umkhuba wokuthuthuka ngokushesha.
Uma kuqhathaniswa nezindwangu ezincibilikayo zebanga lezimboni zendabuko,I-RDP powderinokuqonda okwengeziwe nokuvikelwa kwemvelo, futhi inokumelana ne-asidi okuhle, ukumelana nokugqwala, kanye nokuqina komthelela omkhulu.Enqubweni yokukhiqiza, ukucubungula kanye nokomisa kwe-latex powder, i-latex powder kufanele ibe ngaphansi kokwelashwa okuxutshwe nokushisa nokushisa okuphezulu kokubhaka.Uma ukuvikelwa kochungechunge lwesakhiwo samangqamuzana kunganele ohlelweni lokukhiqiza, i-latex powder ijwayele ukukhiqiza ukuchithwa kwe-Molecular formula thermal oxygen aging, ngaleyo ndlela kulimaza izici nombala wokupenda wokwakha.
