Redispersible latex hmoovNws yog qhov yooj yim heev rau kev tawm tsam ntawm tshav kub thiab oxygen, ua rau muaj ntau cov pa oxygen dawb radicals thiab hydrogen Chloroprene. Covlatex hmoovua rau kev puas tsuaj ntawm polymer saw qhib. Tom qab cov hmoov latex, txheej maj mam muaj hnub nyoog. Redispersible latex hmoov tau txo qhov ci, delamination thiab discoloration. Ntxiv cov tshuaj antioxidants rau latex hmoov tuaj yeem cuam tshuam cov thermal oxidative kev laus tus cwj pwm ntawm polymers.
Tus yuam sij ntawmredispersible latex hmoovsuav nrog Phosphite ester antioxidant thiab thiollipid antioxidant. Kev ua haujlwm ntawm cov hmoov latex yog kom yaj ROOH, kom cov hmoov latex tuaj yeem tsim cov khoom ruaj khov. Kev sib xyaw ua ke ntawm cov ntsiab lus tseem ceeb thiab cov tshuaj tiv thaiv kab mob antioxidant tuaj yeem muaj qee yam kev sib koom ua ke, thiab tuaj yeem raug xa mus ntxiv rau hauv cov hmoov latex kom ua tiav cov txiaj ntsig zoo antioxidant.
Nyob rau hauv xyoo tas los no, nrog rau qhov zoo ntxiv dag zog thiab tob zuj zus ntawm kev tiv thaiv ib puag ncig ntawmRDPnyob rau hauv Suav teb, cov hmoov latex tau hais meej meej tso rau pem hauv ntej zoo dua kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig hauv kev ua vaj tsev coatings. Lub teb ntawm latex hmoov thiab latex hmoov xim tau maj hloov mus rau cov dej soluble, cov ntsiab lus siab, Kev daws teeb meem thiab lwm yam, thiab cov hmoov latex tau txais kev txhim kho sai.
Piv nrog cov tsoos industrial qib hnyav txheej txheej,RDP hmoovmuaj ntau qhov laj thawj thiab kev tiv thaiv ib puag ncig, thiab muaj cov kua qaub zoo, tiv thaiv corrosion, thiab muaj kev cuam tshuam siab toughness. Nyob rau hauv cov txheej txheem ntawm ntau lawm, ua thiab ziab ntawm latex hmoov, latex hmoov yuav tsum raug rau kev sib xyaw cua sov kho thiab kub kub ci. Yog hais tias kev tiv thaiv ntawm molecular qauv saw tsis txaus nyob rau hauv cov txheej txheem ntau lawm, latex hmoov yog nquag tsim Molecular mis thermal oxygen aging dissolution, yog li ua phem rau cov yam ntxwv thiab xim ntawm lub tsev xim.
