Cov qauv tshwj xeeb ntawm 1,1-Dimethyl-3-hydroxybutyl peroxyneodecanoate muab nws qhov kub thiab txias decomposition heev.
Cov yam ntxwv ntawm cov khoom tseem ceeb raws li hauv qab no
qis-kub pib nrog cov pab pawg ua haujlwm zoo
Nws tuaj yeem decompose sai thiab tsim cov dawb radicals ntawm qhov kub thiab txias nyob ib ncig ntawm 45-50℃nrog ib nrab- lub neej, tab sis kuj tso cai rau cov hydroxyl- muaj cov khoom tawg tom qab decomposition ua raws li cov pab pawg reactive, tom qab koom nrog hauv cov polymer sib txuas sib txuas los yog tsim cov khoom sib txuas ntawm cov khoom sib txuas, nrog rau qhov kawg ntawm cov khoom sib txuas. cohesive zog, los yog compatibility nrog fillers.
Zoo heev compatibility
Nws polarity thiab hydrophilicity yog txhim kho raws li lub hav zoov ntawm hydroxyl pawg nyob rau hauv lub molecule. Nyob rau hauv ob qho tib si polar solvents (xws li cawv, ethers, thiab ketones) thiab dej -raws li / polar monomer systems, nws qhia tau zoo heev compatibility thiab dipersion.
Cov txheej txheem ceev polymerization
Nws cov kev ua haujlwm siab tso cai rau cov tshuaj tiv thaiv polymerization yuav tsum tau nqa tawm ntawm qhov kub thiab txias, uas yog qhov tsim nyog rau cov txheej txheem kev lag luam niaj hnub uas yuav tsum tau ua kom luv luv thiab ua haujlwm siab.
Daim ntawv thov
Kev kho ntawm siab -kev ua tau zoo unsaturated polyester composite cov ntaub ntawv.
Nyob rau hauv cov txheej txheem ntawm molding (SMC) los yog pultrusion ntawm unsaturated polyester resin (UPR), cov residual active hydroxyl pawg tso tawm yuav muaj peev xwm txhim khu lub interfacial bonding ntawm cov resin thiab reinforcing cov ntaub ntawv (raws li iav fiber), yog li txhim kho lub zog thiab ntev -lub sij hawm durability ntawm cov ntaub ntawv sib xyaw. Nws yog qhov tsim nyog rau kev tsim khoom siab -kev ua haujlwm ntawm lub tsheb, cua turbine hniav, thiab lwm yam.
Synthesis ntawm siab -kawg polar coatings thiab nplaum resin
Nws cov khoom siv ua haujlwm ntxiv txhim kho qhov ua tau zoo kawg ntawm cov resin, ua rau cov dej -raws li cov txheej txheem kev lag luam, cov ntaub ntawv yas sib xyaw, los yog cov nplaum nplaum ua rau cov tshuaj tiv thaiv ntau dua thiab muaj cov adhesion zoo dua thiab qis dua VOC tsw, yog li ua tau raws li qhov xav tau ntawm kev lag luam siab -kev tiv thaiv ib puag ncig.

FAQ
Q: Vim li cas cov khoom no tshwj xeeb yog tsim rau kev ua haujlwm siab PVC resin ntau lawm?
A: Nws cov yam ntxwv kub tsis tshua muaj peev xwm tswj tau tus nqi polymerization kom raug, tsim cov khoom siv nrog cov pores zoo, txhim kho kev nqus ntawm plasticizer, txo qhov "ntses qhov muag" qhov tsis xws luag, haum rau siab -kuaj tawv tawv thiab khoom siv kho mob tsim khoom.
Q: Dab tsi yog qhov zoo ntawm diisopropyl dicyanitrate peroxide (IPP)?
A: 1,1-Dimethyl-3-hydroxybutyl peroxyneodecanoate muaj qis decomposition kub thiab siab dua reactivity, ceev polymerization tus nqi ntawm tib kub, thiab steric hindrance nyhuv ntawm neodecanoate qauv ua rau nws ruaj khov nyob rau hauv cia.
Q: Dab tsi yog tus nqi tshwj xeeb ntawm cov khoom no hauv kev ntim khoom hluav taws xob?
A: Raws li tus neeg txhawb nqa latent ntawm ib qho -cov khoom siv epoxy nplaum, nws tuaj yeem ua rau thiab kho tau ntawm 80-}100 C, uas tuaj yeem tsis tsuas yog tiv thaiv cov khoom kub-rhiab, tab sis kuj zam qhov kub kub curing zog noj.
