Sezvo fluorescent whitening agent iri chigadzirwa chekuchenesa, nei kushandiswa kwakanyanya mumucheka hakugoni kuichenesa uye kukonzera kuchena kuderera?Morekuru yefluorescent whitening agent ine conjugated double bond system, ine planarity yakanaka.Iyi yakakosha mamorekuru magadzirirwo anogona kutora zvisingaonekwe ultraviolet mwaranzi pasi pezuva, nekudaro kuratidza uye kuburitsa bhuruu-violet mwenje, uye pakupedzisira pajira refiber.Yakasanganiswa nechiedza cheyero, inoburitsa mwenje muchena unoonekwa nemeso, kuitira kuti iwane mhedzisiro yekubvisa yero nekuchena.
Iyo huru inopenya nheyo ye optical brighteners ndeyekupenya kwemaziso, kwete kucheneswa kwemakemikari kunobudisa maitikiro emakemikari.Nokudaro, usati washandisa mavhenekeri ekupenya mumicheka, makemikari akakodzera bleaching anogona kuita kuti optical brighteners ishande.Mhedzisiro huru.Izvo zviri mukati memirairo ye ultraviolet muchiedza chezuva chakavhenekerwa pamucheka uye kuwanda kweiyo fluorescent whitening agent mujira inotsanangurwa zvinoenderana neiyo chena musimboti weiyo chena mumiriri.Aya mapoinzi maviri ari pamusoro anosarudza kuchena kwekuita kweiyo optical inopenya agent mumucheka.
Kana iyo UV yemukati muchiedza chezuva ichikwana, kusungirirwa kwefluorescent whitening agent mujira iri mukati meiyo inoshandiswa, uye kuchena kwechigadzirwa kunowedzera sezvo kusangana kwefluorescent whitening agent kunowedzera.Kana iyo yekumisikidzwa kweiyo fluorescent chena mumiriri inosvika pane imwe yakakwana mwero mumucheka, kuchena mhedzisiro ndiyo yakanyanya kunaka, uye kukosha kwepamusoro kwehuchena hunogona kuwanikwa nechigadzirwa chazvino.Kana huwandu hwe fluorescent brightener inopfuura kukosha kwakakosha iyo ikozvino jira rekugadzira rinogona kushandisa, kuchena kwejira kuchaita yero kana kutoratidza ruvara rwekutanga rweanopenya.Saka iyo yakakwana yekuisa iyo inoshandiswa mumucheka inonzi yellowing point yeinopenya.Saka nei kuchena kunoderera kana huwandu hwekupenya hunoshandiswa mumucheka hwakawandisa?
Kana iyo inopenya yefluorescent inopenya pachigadzirwa chejira inosvika payero yeinopenya, kusimba kweblue-violet mwenje inoratidzwa neinopenya uye yero mwenje pajira inopindirana, uye iyo inopenya mhedzisiro ndiyo yakanyanya kunaka. nguva ino.Uye kana iyo yekumisikidza ichipfuura iyo yero yekupenya kweinopenya, iyo inoratidzwa yebhuruu-violet mwenje inodarika yero mwenje wejira, zvichikonzera yakawandisa yebhuruu-violet mwenje, uye chinhu chekupedzisira neziso rakashama rinoona kuderera kukuru kwekuchena kana kunyange. yellowing.
Naizvozvo, usati wawedzera fluorescent inopenya kuchigadzirwa, sampuli dzinoenderera dzinofanira kutorwa kuti dziyedze iyo yero yemhando yazvino yekupenya mumachira uye zvimwe zvigadzirwa.Kuti ugadzirise iyo yakakwana yekuwedzera huwandu kuti uwedzere kuchena maitiro.
