Mukugadzirwa kwezvigadzirwa zvepurasitiki zvichena, optical brightener chinhu chakakosha chekuwedzera.Kuwedzera chena mumiriri kune zvichena zvigadzirwa zvepurasitiki zvinogona kuvandudza zvakanyanya kuchena uye kupenya kwechigadzirwa, uye zvinobudirira kuvandudza kukwikwidza kwemusika kwechigadzirwa.
Nekudaro, iyo yakawanda iyo inopenya inopenya yakawedzera, zviri nani mhedzisiro.Zvinhu zvechigadzirwa chepurasitiki, maitiro ekugadzira uye tembiricha yekugadzira zvakasiyana, uye huwandu hwekuwedzera hweiyo inopenya inopenya zvakare yakasiyana.
Saka, ndeapi matambudziko anofanirwa kutariswa kana iyo optical brightener inoshandiswa mumapurasitiki, ngatitarisei pazasi.
1. Kuchena mhedzisiro ye optical brightenerKuchena kwekuita kunowanzo kuratidzwa nekuchena.Pamusoro pehuwandu hwekupenya kwakajeka, kuchena kunobatanawo nekuenderana uye kuramba kwemamiriro ekunze kweresin.Iyo inopenya inopenya ine kuenderana kwakanaka uye kuramba kwemamiriro ekunze ine yakanaka yekuchena mhedzisiro uye inogara kwenguva refu.Naizvozvo, iyo yakananga uye inoshanda nzira yekuyedza kuchena mhedzisiro yefluorescent inopenya ndeyekuyedza nemasampuli madiki.
2. Nhamba ye optical brighteneradded Nhamba ye optical brightener kazhinji pakati pe0.05% ne0.1%, uye zvigadzirwa zvega zvinogona kuwedzerwa muhuwandu hukuru.Zvisinei, chiyero che optical brighteneradded haisi nani, asi pane imwe muganhu wekugadzirisa, iyo inodarika Imwe muganhu wemutengo, kwete chete haina kuchena kwekuita, asi yellowing ichaonekwa.
3. Kufurira kwepigment pakuita kuchena Kucheneruka kwechiedza chechiedza chinopenya chinopindirana, chinoshandura chiedza che ultraviolet kuva chiedza chinooneka chebhuruu kana blue-violet kuti chizadzise chinangwa chekuchena.Naizvozvo, izvo zvinoumba izvo zvinonyanya kukanganisa pane optical inopenya pachayo ndezviya zvinogona kutora ultraviolet chiedza, senge titanium dioxide, ultraviolet absorbers uye zvichingodaro.Anatase titanium dioxide inogona kutora 40% yechiedza pa300nm, uye rutile mhando inogona kutora 90% yechiedza pa380nm.Kazhinji, kana titanium dioxide uye optical brightenerare inoshandiswa panguva imwe chete, zvakanakisisa kushandisa anatase titanium dioxide.Kazhinji kutaura, kana kusangana kwe optical brightener zvakafanana, kuchena kunowanikwa kana zinc sulfate inoshandiswa ndiyo yakasimba, inoteverwa neanatase titanium dioxide, uye rutile titanium dioxide ndiyo isina simba.
4. Mhedzisiro ye ultraviolet absorbers Mushonga we ultraviolet unogona kutora chiedza che ultraviolet, asi chinogona kuderedza kuchena kwechiedza che fluorescent whitening agent.Naizvozvo, mune zvigadzirwa zvinoshandisa fluorescent whitening agents, zviri nani kusarudza histamine light stabilizers izvo zvisingachinji ruvara.Kana iwe uchifanira kuwedzera UV absorber, iwe unofanirwa kuwedzera zvakakodzera huwandu hwekupenya.Pamusoro pezvo, zvinhu zvakaita sekuti midziyo yekugadzira yakachena, kuchena kwepurasitiki, uye hunyoro hwemukati zvese zvine chimwe chinokanganisa pakuchena.
