Reactive light stabilizer
China's resin (yakatsanangurwa zvakafara, chero polymer mukomboni inogona kushandiswa seyakagadzirwa zvinhu zvepurasitiki zvigadzirwa kugadzira inonzi resin) indasitiri iri kukura nekukurumidza.Kubuda kwechigadzirwa kuri kuramba kuchikura, uye mutemo wenyika maindasitiri unokurudzira indasitiri yeresin kuti isimudzire munzira yezvigadzirwa zvepamusoro-soro.Iwo akasiyana-siyana eChina resin anga akakwana, asi kana zvichienzaniswa nevekune dzimwe nyika vepamberi, kuchine imwe gap muchiyero chekugadzira, kutonga kwemaitiro uye zvimwe zvigadzirwa zvine zvakakosha kuita zvinodiwa.Naizvozvo, mumakore mashoma anotevera, chete kutsvagisa uye kuvandudzwa kwezvigadzirwa zvemhando yepamusoro, kuvandudza kugadzikana kwemhando yechigadzirwa, ndiyo nyaya yekukurumidzira yekuvandudza resin, yakakoshawo.
Iyo resin zvinhu zviri nyore kuchembera, kana yavhenekerwa kuchiedza, iyo isina unsaturated kaviri chisungo muchimiro chemolecular kana iyo isina kuchena zvinhu mukuita izvi zvinonyanya kutyora kuparara kwebhondi, mahara radical chain reaction, uye kukurudzira chizvarwa cheruvara. boka, pakupedzisira rinotungamira kune resin kupera uye kuputika.Kuti ugadzirise dambudziko refotoaging resin, zvinodikanwa kuwedzera photostabilizer kune resin kuitira kuti inhibisa kana kunonoka iyo photoaging process uye kurebesa hupenyu hwayo hwesevhisi.
Chiedza stabilizer imhando yeanobatsira mumiriri iyo inogona kumisa kana kunonoka kuomeswa kwemafoto eresin.Munguva yese yekuvandudza uye mamiriro ekutsvagisa kumba nekune dzimwe nyika, kusimudzira uye kutsvagisa kwemwenje stabilizer kunoratidza mamwe maitiro matsva uye hunhu, kutsvaga hunoshanda, kuchengetedza kwezvakatipoteredza, hupfumi uye kusangana nekuomarara kugadzirisa uye kushandiswa kwenzvimbo yemhando nyowani dzemwenje stabilizer, chimiro chitsva. chagara chiri chinangwa chekusimudzira maindasitiri nekutsvaga.Kunyanya, inzvimbo yakakosha yekusimudzira yemwenje inodzikamisa kubatanidza mapoka anoshanda akasiyana mune imwe molecule kuita kuti morekuru ive neakawanda anoshanda reactivity uye kuvandudza kushanda kwayo.Nekuunza kemikari bond ye reactive monomer mu resin bazi cheni kana main chain, iyo reactive light stabilizer inogona kutamba hunhu hwesimba rakakwirira uye kunyungudika kupikisa uye kureruka kweresin, ine tarisiro yakasimba yekushandisa.Kuwedzerwa kweiyo reactive light stabilizer kune resin hakuzokanganisa zvakanyanya chimiro chemolecular resin, asi inogona kuvandudza zvimwe zvimiro zveresin pachayo kukanganisa, uyezve kugadzirisa mashandiro uye kushandisa mashandiro eresin, kuvandudza kukosha kwekushandisa uye sevhisi. hupenyu hwe resin.
Reactive light stabilizer inoreva kuunzwa kwemapoka anochinja-chinja muchimiro chemolecular yeamine yakavharika, kuitira kuti inosungirirwa kana kunamatidzwa pamusana wepolymer panguva yekugadziriswa kwezvigadzirwa zvepolymer kuti igadzire inogara iri fototable polymer ine akavharika amine anoshanda mapoka.Iyi mwenje stabilizer inogona kunyatso dzivirira kutama kwemuviri kana kuputika kunokonzerwa nekurasikirwa kwechiedza stabilizer, kunatsiridza nekuvandudza kupararira kweyakavharika amine light stabilizer mupolymer uye mhedzisiro yekudzikamisa kwechiedza, kunyanya mushure mekugadzirwa kwepolymer chigadzirwa uye kugadzirwazve. , boka rekudzikamisa chiedza rinogona kuramba richitamba chiedza chakanaka chekudzikamisa.Iko kusungirirwa kwechigarire kweakavharika amine molecule kune iyo polymer musana nemapoka anochinja ndiyo nhanho inoshanda yekugadzirisa dambudziko rekusingaperi photostability yezvigadzirwa zvepurasitiki.Makambani ekune dzimwe nyika anosanganisira Japan Showa Denko, Adico, nezvimwewo, akatanga methacrylate seboka rinoshanda rechiedza chekudzikamisa agent, ine zvirinani kudzikamisa mwenje.Asi boka remethacrylate harina kugadzikana, mukugadzirwa kwechido chekuwedzera polymerization inhibitor kudzivirira kuitika kwe self-polymerization, saka hazvidzivisiki kuwedzera kuoma kwemashure ekurapa.Pamusoro pezvo, methacrylate chinhu chinoputika chine muchetura uri pakati nepakati, chinokuvadza kune vanoshanda.
Iyo reaction light stabilizer ine pazasi zvakanakira:
zvinhu zvakachengeteka mbishi;
zvakatipoteredza;
iyo catalyst ine hupfumi uye inoshanda;
nzira yekugadzirira iri nyore uye mutengo wezvinhu wakaderera wakaderera, unogona kuva wakawanda
inoshandiswa mukugadzirwa kwemaindasitiri, kuitira kukudziridza zvikumbiro muminda yepamusoro-yekupedzisira ruzivo rwemagetsi emakemikari uye photoresist.
