Reactive lub teeb stabilizer

Tuam Tshoj cov resin (hais dav dav, txhua qhov sib xyaw polymer uas tuaj yeem siv los ua cov khoom siv raw rau cov khoom siv yas yog hu ua resin) kev lag luam tau tsim sai.Cov khoom tsim tawm txuas ntxiv nthuav dav, thiab lub teb chaws txoj cai kev lag luam txhawb nqa kev lag luam resin los txhim kho cov khoom siv high-tech.Cov ntau yam ntawm Tuam Tshoj cov resin tau kuj zoo kawg nkaus, tab sis piv nrog txawv teb chaws advanced counterparts, tseem muaj ib tug tej yam sib txawv nyob rau hauv ntau lawm scale, txheej txheem tswj thiab ib co khoom nrog tshwj xeeb kev ua tau zoo.Yog li ntawd, nyob rau hauv ob peb xyoos tom ntej no, tsuas yog kev tshawb fawb thiab kev loj hlob ntawm cov khoom ua tau zoo, txhim kho kev ruaj ntseg ntawm cov khoom zoo, yog qhov tseem ceeb ntawm resin txoj kev loj hlob, kuj tseem ceeb.

Cov khoom siv cob yog yooj yim rau kev laus, thaum nws raug rau lub teeb, cov unsaturated ob daim ntawv cog lus nyob rau hauv cov qauv molecular los yog cov khoom tsis huv nyob rau hauv tus txheej txheem yog feem ntau yuav ua txhaum cov nyiaj deterioration, dawb radical saw cov tshuaj tiv thaiv, thiab induce lub tiam ntawm cov xim. pab pawg, nws thiaj li ua rau cov resin ploj thiab tawg.Yuav kom daws tau qhov teeb meem ntawm photoaging ntawm resin, nws yog ib qhov tsim nyog yuav tau ntxiv ib tug photostabilizer rau cov resin thiaj li inhibit los yog ncua cov txheej txheem photoaging thiab ncua nws cov kev pab cuam lub neej.

Lub teeb stabilizer yog ib hom kev pabcuam tus neeg sawv cev uas tuaj yeem cuam tshuam lossis ncua sijhawm photodegradation ntawm resin.Thoob plaws hauv txoj kev loj hlob thiab kev tshawb fawb nyob rau hauv tsev thiab txawv teb chaws, kev txhim kho thiab kev tshawb fawb ntawm lub teeb stabilizers qhia ib co tshiab tiam sis thiab cov yam ntxwv, nrhiav kom tau zoo, ib puag ncig tiv thaiv, kev lag luam thiab ua tau raws li qhov hnyav ua thiab daim ntawv thov ib puag ncig ntawm ntau yam tshiab ntawm lub teeb stabilizers, cov qauv tshiab. ib txwm yog lub hom phiaj ntawm kev tsim kho kev lag luam thiab kev tshawb fawb.Tshwj xeeb, nws yog ib qho tseem ceeb ntawm txoj kev loj hlob ntawm lub teeb stabilizers los ua ke cov pab pawg ua haujlwm sib txawv hauv ib lub molecule los ua kom cov molecule muaj ntau yam reactivity thiab txhim kho nws cov efficiency.Los ntawm kev qhia cov tshuaj tiv thaiv ntawm reactive monomer rau hauv resin ceg saw los yog cov saw tseem ceeb, lub teeb reactive stabilizer tuaj yeem ua tus yam ntxwv ntawm lub zog siab thiab hnyav tsis kam thiab lub teeb ua haujlwm ntawm cov resin, uas muaj cov ntawv thov muaj zog.Qhov sib ntxiv ntawm reactive lub teeb stabilizer rau cov resin yuav tsis cuam tshuam rau cov qauv molecular ntawm cov resin, tab sis tuaj yeem txhim kho qee cov khoom ntawm cov resin nws tus kheej tsis xws luag, thiab tom qab ntawd txhim kho kev ua haujlwm thiab kev siv cov khoom siv, txhim kho kev siv tus nqi thiab kev pabcuam. lub neej ntawm cov resin.

Reactive lub teeb stabilizer hais txog kev taw qhia ntawm cov pab pawg reactive rau hauv cov qauv molecular ntawm cov blocked amine, yog li ntawd nws yog bonded los yog grafted mus rau lub polymer qaum thaum lub sij hawm ua cov khoom polymer los tsim ib tug mus tas li photostable polymer nrog blocked amine functional pawg.Lub teeb stabilizer no tuaj yeem zam lub cev tsiv teb tsaws lossis volatilization tshwm sim los ntawm qhov poob ntawm lub teeb stabilizer, txhim kho thiab txhim kho cov dispersion ntawm blocked amine lub teeb stabilizer nyob rau hauv lub polymer thiab cov nyhuv ntawm lub teeb stabilization, tshwj xeeb tshaj yog tom qab cov khoom siv polymer rov ua dua thiab rov ua dua. , lub teeb stabilizing pab pawg tseem tuaj yeem ua lub teeb pom kev zoo.Kev sib txuas mus tas li ntawm cov blocked amine molecule rau cov pob txha polymer los ntawm cov pab pawg reactive yog ib qho kev ntsuas zoo los daws qhov teeb meem ntawm cov khoom siv yas mus tas li.Cov tuam txhab txawv teb chaws suav nrog Nyij Pooj Showa Denko, Adico, thiab lwm yam, tau tsim cov methacrylate ua ib pawg reactive ntawm lub teeb stabilization tus neeg saib xyuas, nrog rau lub teeb stabilization zoo dua.Tab sis methacrylate pawg tsis ruaj khov, nyob rau hauv cov synthesis ntawm qhov yuav tsum tau ntxiv polymerization inhibitor kom tsis txhob muaj qhov tshwm sim ntawm tus kheej-polymerization, yog li nws yog inevitable ua rau kom qhov nyuaj ntawm kev kho mob tom qab.Tsis tas li ntawd, methacrylate yog ib yam khoom uas tsis muaj tshuaj lom nrog cov tshuaj lom neeg nruab nrab, uas tsim kev puas tsuaj rau cov neeg ua haujlwm.

Cov tshuaj tiv thaiv lub teeb stabilizer muaj cov hauv qab no zoo:
ruaj ntseg raw khoom;
ib puag ncig tus phooj ywg;
lub catalyst yog kev lag luam thiab ua haujlwm zoo;
txoj kev npaj yog qhov yooj yim thiab cov khoom siv raw tus nqi qis, uas tuaj yeem ua tau dav
siv nyob rau hauv industrial ntau lawm, thiaj li yuav tsim daim ntaub ntawv nyob rau hauv lub teb ntawm high-end hluav taws xob cov ntaub ntawv chemicals thiab photoresist.
