Kev npaj thiab ua kev tshawb fawb txog cov rwb thaiv tsev thermal thiab nplaim taws retardant txheej rau cov roj tso tsheb hlau roj

Kev tso tsheb hlau luam av roj feem ntau muaj cov peev xwm loj thiab raug rau cov khoom siv, ua rau muaj kev pheej hmoo roj loj loj. Txhawm rau txo cov roj poob qis, tiv thaiv cov hluav taws xob tank, thiab kev thauj cov roj tsheb tso tsheb hlau luam thiab nplaim hluavtaws rov ua zoo. Kev tshawb fawb thiab kev txhim kho txheej txheej nrog ob lub rwb thaiv tsev thermal thiab nplaim taws retardancy rau kev thov cov chaw tso roj sab nrauv yog qhov kev daws teeb meem zoo rau cov teeb meem no. Microcapsule theem hloov pauv (MCPCMS) nrog cov khoom siv pvc {3} {{3} - situ polymerization. Cov teebmeem ntawm ntau txoj kev npaj, suav nrog emulsifier cov ntsiab lus thiab sib piv, ntawm cov khoom siv morphaology, thiab cua sov cia khoom ntawm cov khoom siv hluav taws xob hloov pauv tau tshawb xyuas. Cov txiaj ntsig tau pom tias sib txawv ntawm cov ntsiab lus emulsifier uas tau ua rau muaj kev hloov kho microcapsulity, encapsulation efficiulation kev ua kom muaj kev txuag hluav taws xob ntxiv mus txog 54.0%. Tsis tas li ntawd, Aluminium thoob plaws yog qhov chaw tau hloov kho nrog lub ntsuas hluav taws xob (}} Infrared spectroscopy, tsom xam me me, thiab ua kom muaj kev ntsuas kom haum los ntawm 0.5 {}} Tsis tas li ntawd, cov khoom saum npoo ntawm txhuas hydroxide tau hloov los ntawm hydrophilic rau oleophobic. Ntawm lub hauv paus ntawm cov saum toj no, raws li cov txheej txheem sib xyaw ntawm ephaturete hloov cov khoom siv yog ntxiv rau epoxy ricking hlau los ua ib qho kev hloov kho hauv nruab nrab; Micron Aluminium hydroxide fydrame retardant yog ntxiv rau epoxy Retret thiab tov nplua nuj thiab sib xyaw ua ke los ua ib txheej txheej txheem txheej txheem. Ua ke nrog cov kev ua kom zoo ntawm txheej txheej txheej txheej txheej, hloov cov txheej txheem hloov kho yog npaj. Qhov cuam tshuam ntawm kev sib ntxiv ntawm cov microcapsule theem hloov pauv thiab saum npoo {{{{{{{{{{{{{{{{{ Txoj kev tshawb fawb no qhia tau hais tias lub viscosity thiab tsis- cov ntsiab lus rwb thaiv cov ntsiab lus nce nrog cov qauv hluav taws xob nce ntxiv nrog cov qauv hauv tebchaws rau txheej txheej. Qhov kev kuaj pib ua haujlwm yooj yim xws li yoog tau, cuam tshuam kuj ntawm cov thermal rwb thaiv tsev thiab nplaim taws retardant txheej tom qab txheej yog nqa tawm. Cov txiaj ntsig kev sim coj ua qhia tau qhia tias thaum microcapsule ntxiv tus nqi mus txog 12 wt.% Ntawm cov cua sov hluav taws xob muaj cov khoom siv tshuab thiab dej tsis kam. Kev ntxiv rau saum npoo - ri}} recified aluminium cov txiaj ntsig tsis zoo thiab cov nplaim taws kev hloov kho cov nplaim hluav taws xob. Txoj kev tshawb no tau qhia tias hauv kev tswj hwm hluav taws xob ntawm thermium rwb thaiv cov txheej txheem xim nrog 3 wt.%, 6 wt.% Thiab 9 wt.% Thiab 9 wt.% Thiab 9 wt.% Thiab 9 wt.% Thiab 9 wt.% Ntawm lawv, cov thermal rwb thaiv tsev kub ntawm lub epoxy micracapeanous hlau nruab nrab tau mus txog 6.7 degree, thiab lub thermal rwb thaiv tsev kev ua haujlwm ntawm txheej yog qhov zoo. Epoxy Zinc-} Primer nplua nuj nrog 9 wt. Lub sij hawm sib txuas lus pom tias cov nplaim retardant sij hawm tuaj yeem ncav cuag 330s thiab cheeb tsam carbonancation yog 3328mm2., Uas cuam tshuam ntau dua cov nplaim hluav taws xob rov ua haujlwm ntawm txheej. Lub epoxy zinc-nplua nuj xim nrog 9 wt.% Kho cov xim txhuas epoxy moturally todcoat, cov ntawv sab nrauv tiv thaiv kev tiv thaiv cov roj av tso tawm rau cov roj tso tsheb hlau luam. Cov khoom siv sib xyaw tau sim rau cov khoom tseem ceeb xws li tuab thiab cuam tshuam nrog thermal rwb thaiv tsev, nplaim hluav taws xob rov qab, thiab UV laus tiv taus. Cov txiaj ntsig kev sim ua tau pom tias cov txheej txheej composite tau muaj qhov nruab nrab tuab ntawm 261.14μm thiab zoo heev neeg kho tshuab hluav taws xob. Nws cov kev rwb thaiv tsev thermal tau txhim kho los ntawm 0.6℃piv rau tib txheej, thiab nws cov nplaim roj, thiab nws cov nplaim rov qab ntev dua 22 feeb ntev dua li tag nrho cov txheej. UV Kev Tshawb Fawb Kev Tshawb Fawb tau qhia tawm uas ob qho tib si ntawm cov xim ci thiab pom cov txiaj ntsig ci ntawm qib 1, qhia txog kev ua kom zoo UV kev tiv thaiv zoo.
