Izithasiselo ezisebenzayo aaa i-UV esebenzayo, i-LS esebenzayo, i-double bond reactive addititive Isithombe Esifakiwe

incazelo emfushane:

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Isinzinzisi sokukhanya esisebenzayo

I-resin yaseChina (echazwe kabanzi, noma iyiphi inhlanganisela ye-polymer engasetshenziswa njengempahla eluhlaza yokucubungula imikhiqizo yepulasitiki ibizwa nge-resin) imboni ikhula ngokushesha.Ukukhiqizwa komkhiqizo kuyaqhubeka nokukhula, futhi inqubomgomo kazwelonke yezimboni ikhuthaza imboni ye-resin ukuthi ithuthuke ekuqondeni kwemikhiqizo yobuchwepheshe obuphezulu.Izinhlobonhlobo ze-resin yaseShayina bezilungile uma kuqhathaniswa, kodwa uma kuqhathaniswa nozakwabo abathuthukile bakwamanye amazwe, lisekhona igebe elithile esikalini sokukhiqiza, ukulawula inqubo kanye neminye imikhiqizo enezidingo ezikhethekile zokusebenza.Ngakho-ke, eminyakeni embalwa ezayo, ucwaningo nokuthuthukiswa kwemikhiqizo ephezulu kuphela, ukuthuthukisa ukuzinza kwekhwalithi yomkhiqizo, kuyindaba ephuthumayo yokuthuthukiswa kwe-resin, nayo iyisisekelo.

Izinto ze-resin kulula ukuguga, lapho zivezwa ekukhanyeni, isibopho esiphindwe kabili esingagcwalisiwe esakhiweni samangqamuzana noma izinto ezingcolile ngesikhathi senqubo maningi amathuba okuba aphule ukuwohloka kwebhondi, ukusabela kweketango lamahhala, futhi kubangele ukukhiqizwa kombala. iqembu, ekugcineni okuholela ekutheni i-resin iphele futhi iqhekeke.Ukuze uxazulule inkinga ye-photoaging ye-resin, kuyadingeka ukwengeza i-photostabilizer ku-resin ukuze uvimbele noma ubambezele inqubo ye-photoaging futhi wandise impilo yayo yesevisi.

I-light stabilizer iwuhlobo lwe-ejenti eyisizayo engavimbela noma ibambezele ukuwohloka kwesithombe kwe-resin.Kuyo yonke intuthuko kanye nesimo socwaningo ekhaya nakwamanye amazwe, ukuthuthukiswa kanye nocwaningo lwezinzinzisi ukukhanya kukhombisa izitayela ezintsha kanye nezici, ukufuna ukusebenza kahle, ukuvikelwa kwemvelo, umnotho kanye nokuhlangabezana nokucubungula nokusetshenziswa kwemvelo enzima yezinhlobo ezintsha zokuqinisa ukukhanya, isakhiwo esisha. bekulokhu kuwumgomo wokuthuthukiswa kwezimboni nocwaningo.Ikakhulukazi, kuyisiqondiso esibalulekile sokuthuthukiswa kweziqinisi zokukhanya ukuhlanganisa amaqembu ahlukene asebenzayo ku-molecule eyodwa ukwenza i-molecule ibe nokuphindaphinda kwemisebenzi eminingi futhi ithuthukise ukusebenza kahle kwayo.Ngokwethula isibopho samakhemikhali se-monomer esebenzayo ochungechungeni lwegatsha le-resin noma iketango eliyinhloko, isigxivizo sokukhanya esisebenzayo singadlala izici zamandla aphezulu kanye nokumelana nezinyibilikisi kanye nokumelana nokukhanya kwe-resin, okunethemba eliqinile lokusetshenziswa.Ukwengezwa kwe-reactive light stabilizer ku-resin ngeke kuthinte kabi ukwakheka kwamangqamuzana e-resin, kodwa kungathuthukisa izici ezithile ze-resin ngokwayo amaphutha, bese kuthuthukisa ukusebenza kokucubungula nokusebenzisa ukusebenza kwe-resin, kuthuthukise inani lokusetshenziswa nesevisi. impilo ye-resin.

I-Reactive light stabilizer isho ukwethulwa kwamaqembu asebenzayo esakhiweni samangqamuzana e-amine evinjiwe, ukuze iboshwe noma ixhunywe kumgogodla we-polymer ngesikhathi sokucutshungulwa kwemikhiqizo ye-polymer ukuze kwakhe i-polymer ethwebulayo ehlala njalo enamaqembu asebenzayo e-amine avinjiwe.Lesi siqinisi sokukhanya singagwema kahle ukufuduka komzimba noma ukuguquguquka okubangelwa ukulahleka kwesizinzisi sokukhanya, sithuthukise futhi sithuthukise ukuhlakazwa kwe-amine light stabilizer evinjiwe ku-polymer kanye nomthelela wokuqiniswa kokukhanya, ikakhulukazi ngemuva kokuvuselelwa kabusha nokukhiqizwa kabusha komkhiqizo we-polymer. , iqembu lokuzinzisa ukukhanya lisengadlala umphumela omuhle wokuzinzisa ukukhanya.Ukuhlanganiswa okuhlala njalo kwe-amine molecule evinjiwe kumgogodla we-polymer ngamaqembu asebenzayo kuyisinyathelo esisebenzayo sokuxazulula inkinga ye-photostability yaphakade yemikhiqizo yepulasitiki.Izinkampani zakwamanye amazwe ezihlanganisa i-Japan Showa Denko, i-Adico, njll., zethule i-methacrylate njengeqembu elisebenzayo le-ejenti yokuqinisa ukukhanya, enomphumela ongcono wokuzinzisa ukukhanya.Kodwa iqembu le-methacrylate alizinzile, ekuhlanganiseni kwesidingo sokwengeza i-polymerization inhibitor ukugwema ukuvela kwe-self-polymerization, ngakho-ke akunakugwenywa ukwandisa ubunzima bokwelashwa ngemva kokwelashwa.Ngaphezu kwalokho, i-methacrylate iyinto eshintshashintshayo enobuthi obumaphakathi, obuyingozi kubaqhubi.

I-reaction light stabilizer inezinzuzo ezingezansi:
izinto zokusetshenziswa eziphephile;
ubungane bemvelo;
i-catalyst iyonga futhi iyasebenza;
indlela yokulungiselela ilula futhi intengo yempahla eluhlaza iphansi, engaba kabanzi
esetshenziswa ekukhiqizweni kwezimboni, ukuze kuthuthukiswe izinhlelo zokusebenza emkhakheni wamakhemikhali olwazi lwe-elekthronikhi aphezulu kanye ne-photoresist.
