Nhanganyaya yeOptical brightener OB-1
Optical brightener OB-1,2,2- (4,4-distyreneyl) dibenzoxazole chinhu cheyero checrystalline chine kunyungudika kwe359-362 ℃. Haina kunyungudika mumvura, haina kunhuwa, uye ine kuita kwakagadzikana. Iyo yakanyanya kunyura spectrum wavelength i374nm, uye ine yakasimba fluorescence ine fluorescence emission wavelength ye434nm. Optical brightener OB-1 is an optical brightener inoshandiswa papolyester fibers, uye inoshandiswa zvakanyanya mumapurasitiki akadai seABS, PS, HIPS, PC, PP, PE, EVA, uye yakaoma PVC. Iyo ine yakanakisa kuchena mhedzisiro, yakanakisa thermal kugadzikana, uye kushoma kuwedzera.
MaOptical blighteners anogona kutora zvisingaoneki ultraviolet mwenje (ine wavelength kureba ingangoita 360-380nm) uye ichishandura kuita yakareba wavelength yebhuruu kana yepepuru inooneka mwenje, nokudaro kutsiva kudiki kudiki kweyero mumatrix. Panguva imwecheteyo, dzinoratidza chiedza chinooneka kupfuura chiitiko chekutanga chavelength muhuwandu hwe400-600nm, zvichiita kuti chigadzirwa chionekwe chakachena, chakajeka, uye chinowedzera simba.
Kushandiswa kweOptical brightener OB-1
Ichi chigadzirwa chakakodzera kuchena uye kupenya mapurasitiki akadai sePVC, PE, PP, ABS, PC, PA, etc. Ine yakaderera dosage, yakasimba kuchinjika, uye yakanaka dispersibility. Ichi chigadzirwa chine muchetura wakanyanya kuderera uye chinogona kushandiswa kuchena mapurasitiki anoshandiswa mukurongedza chikafu uye matoyi evana. Inogona kuwedzerwa panguva yekumashure-kugadzirisa kana polymerization, uye iyo yakacheneswa zvinhu zvine kuchena kwakanyanya uye yakanakisa kupisa uye kuramba kwemamiriro ekunze. OB-1 inogona zvakare kugadzirwa kuita paste yekuchenesa machira.
Zvakanakira zveOptical brightener OB-1
1.Kubva pamaonero ekudzivirira tembiricha:
Optical brightener OB-1 ine nzvimbo yakanyunguduka inopfuura 350 ℃ uye parizvino ndiyo inonyanya kusapisa pakati pezvigadzirwa zvese zvinopenya zvinopenya. Kune maboss anogadzira epamusoro-tembiricha anodzivirira mapurasitiki, optical brightener OB-1 inonyanya kukodzera.
Sezvinozivikanwa, indasitiri yepurasitiki iindasitiri yakafara uye yakasiyana-siyana ine akawanda marudzi uye maitiro. Iyo tembiricha yekugadzira yezvigadzirwa zvepurasitiki yakawanda yakakwira, zvimwe zvinotosvika pamusoro pe300 degrees Celsius. Parizvino, chete optical brightener OB-1 inogona kumira kutonhora kwakakwirira kwakadaro, iyo iriwo mukana weiyo optical brightener OB-1.
2. Kutarisa kubva pachiedza chefluorescent chakabudiswa
Zvigadzirwa zvakasiyana zve optical brightener zvine mavara akasiyana, zvimwe zvinopenya zvinoburitsa mwenje weblue, nepo zvimwe zvinoburitsa bhuruu yepepuru mwenje. Zvizhinji zvezvakagadzirwa muzvisikwa ndezveyero, uye chiedza cheyero chakasanganiswa nechiedza chebhuruu chinoburitsa chiedza chichena. Naizvozvo, zvinopenya zvinopenya zvine huremu hwebhuruu mwenje zvine zvirinani fluorescence uye chena mhedzisiro, uye huwandu hwakawedzerwa zvakare hushoma.
Optical brightener OB-1 inogona kukamurwa kuita girinhi chikamu uye yero chikamu maererano nechitarisiko. Iyo fluorescence inoburitswa nechikamu chegirinhi inorerekera kuchiedza chebhuruu, nepo fluorescence inoburitswa neyero chikamu inorerekera kuchiedza chebhuruu chepepuru. Naizvozvo, ndosaka vatengi vazhinji vachisarudza iyo yakasvibira chikamu cheOptical Brightener OB-1 mazuvano.
