I-latex powder enokuchithwa kwakhonaisengozini kakhulu kuhlaselo lobushushu kunye neoksijini, nto leyo ekhokelela kuninzi lweeradicals zasimahla zeoksijini kunye nehydrogen Chloroprene.Ilatex powderkukhokelela ekutshatyalalisweni kokuvulwa kwekhonkco le-polymer.Emva komgubo we-latex, ukugquma ngokuthe ngcembe kuyaguga.Umgubo welatex odispersible unciphise ukuqaqamba, ukunyibilika komphezulu kunye nokutshintsha kombala.Ukongeza i-antioxidants kwi-latex powder inokuthintela ngokufanelekileyo indlela yokuguga ye-oxidative ye-polymers.
Isitshixo sei-latex powder enokuchithwa kwakhonaiquka iPhosphite ester antioxidant kunye nethiolipid antioxidant.Indlela yokusebenza ye-latex powder kukuchitha i-ROOH, ukwenzela ukuba i-latex powder ikwazi ukwenza amacandelo azinzileyo.Ukudityaniswa kwe-antioxidants ephambili kunye neyokuncedisayo ingaba nefuthe elithile le-synergistic, kwaye inokusasazwa ngakumbi kwi-latex powder ukufezekisa ukusebenza okungcono kwe-antioxidant.
Kwiminyaka yakutshanje, ngokuqiniswa okukhulu kunye nokuqiniswa kokhuseleko lokusingqongileyoiRDPe-China, i-latex powder ibeke ngokucacileyo ugcino lwamandla aphezulu kunye nemimiselo yokukhusela indalo kwintsimi yokwakha iingubo.Intsimi ye-latex powder kunye nepeyinti yomgubo we-latex iye yaguquka ngokuthe ngcembe ekubeni yi-soluble yamanzi, umxholo ophezulu oqinileyo, iSolvation kunye neminye imiba, kunye ne-latex powder ifumene intsingiselo yophuhliso olukhawulezayo.
Xa kuthelekiswa nemigangatho yemveli yotyalo lokunyibilikisa,RDP powderinengqiqo ngakumbi kunye nokukhuselwa kokusingqongileyo, kwaye inokumelana ne-asidi elungileyo, ukuxhathisa umhlwa, kunye nokuqina kwempembelelo ephezulu.Kwinkqubo yokuvelisa, ukucutshungulwa kunye nokomisa i-latex powder, i-latex powder kufuneka ixhomekeke kunyango oluxubileyo lobushushu kunye nokubhaka okuphezulu kweqondo lokushisa.Ukuba ukukhuselwa kwekhonkco le-molecular structure akwanelanga kwinkqubo yokuvelisa, i-latex powder ijwayele ukuvelisa i-molecular formula thermal oxygen aging dissolution, ngaloo ndlela ilimaza iimpawu kunye nombala wepeyinti yesakhiwo.
