Impushana ye-latex ehlakazeka kabushaisengozini kakhulu 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 ekukhiqizeni, i-latex powder ijwayele ukukhiqiza ukuchithwa kwe-Molecular formula thermal oxygen aging, ngaleyo ndlela kulimaza izici nombala wokupenda wokwakha.
