I-Optical Brightener VBL
Ifomula yesakhiwo
INOMBOLO YECAS: 12224-16-7
Ifomula ye-molecular: C36H34N12O8S2Na2 Isisindo se-molecular: 872.84
Inkomba Yekhwalithi
1. Ukubukeka: impushana ephuzi ekhanyayo
2. Umthunzi: Blue Violet
3. I-Fluorescence intensity (ilingana nomkhiqizo ojwayelekile): 100,140,145,150
3. Umswakama: ≤5%
5. Amanzi angancibiliki: ≤0.5%
6. Ubuhle (izinga lokugcinwa kwesisefo ngokusebenzisa isisefo esivamile semeshi engu-120): ≤5%
Ukusebenza Nezici
1. I-anionic futhi ingasetshenziswa kubhavu ofanayo nama-anionic surfactants noma odayi, ama-non-ionic surfactants kanye ne-hydrogen peroxide.
2. Akufanelekile ukusetshenziswa ekugezeni okufanayo nama-cationic surfactants noma odayi.
3. I-ejenti emhlophe ye-fluorescent i-VBL izinzile kumpushana womshwalense.
4. I-Fluorescent brightener VBL ayimelani nama-ion ensimbi njengethusi nensimbi.
Ububanzi Besicelo
1. Isetshenziselwa ukwenza mhlophe ukotini kanye nemikhiqizo emhlophe ye-viscose, kanye nemikhiqizo ekhanyayo enombala okhanyayo noma ephrintiwe, ngokushesha kokukhanya okujwayelekile, ukuhlobana okuhle kwamafayibha e-cellulose, izakhiwo zokulinganisa ezijwayelekile, ukuphrinta, ukudaya, ukudaya kwephedi futhi Ifanele ukunamathisela ukuphrinta.
2. I-Fluorescent brightener VBL ingasetshenziselwa ukwenza mhlophe i-vinylon nemikhiqizo yenayiloni.
3. Isetshenziselwa ukwenza mhlophe kwemboni yephepha, i-pulp noma upende.
Iziyalezo
1. Embonini yephepha, i-agent emhlophe ye-fluorescent i-VBL ingancibilika emanzini futhi yengezwe ku-pulp noma upende.
Embonini yephepha, sebenzisa izikhathi ezingu-80 zamanzi ukuncibilikisa i-agent emhlophe ye-fluorescent i-VBL bese uyengeza ku-pulp noma ukunamathela.Inani liyi-0.1-0.3% yesisindo se-pulp eyomile ngethambo noma i-bone-dry coating.
2. Embonini yokunyathelisa nokudaya, i-agent emhlophe ye-fluorescent i-VBL ingangezwa ngokuqondile ku-vat yokudaya, futhi ingasetshenziswa ngemva kokuncibilika emanzini.
Umthamo
0.08-0.3%, isilinganiso sokugeza: 1:40, izinga lokushisa elingcono kakhulu lokudaya: 60℃
Isitoreji Nezinyathelo Zokuqaphela
1. Kunconywa ukuthi ugcine i-agent emhlophe ye-fluorescent i-VBL endaweni epholile, eyomile futhi ugweme ukukhanya.Isikhathi sokugcina iminyaka emi-2.
2. Isikhathi sokugcina se-ejenti emhlophe ye-fluorescent VBL singaphezu kwezinyanga ezi-2.Inani elincane lamakristalu livunyelwe, futhi umphumela wokusetshenziswa ngeke uthinteke ngesikhathi sokuphila kweshalofu.
3. I-VBL ekhanyayo ingaxutshwa nama-anionic kanye nama-non-ionic surfactants, amadayi aqondile, ane-acidic namanye ama-anionic, amapende, njll. Ayifaneleki ukusetshenziselwa ukugeza okufanayo namadayi we-cationic, ama-surfactants, nama-synthetic resins.
4. Izinga lamanzi elingcono kakhulu kufanele kube amanzi athambile, okungafanele aqukathe ama-ion ensimbi njengethusi nensimbi ne-chlorine yamahhala, futhi kufanele alungiswe ngokushesha ngemva kokusetshenziswa.
5. Umthamo we-agent emhlophe ye-fluorescent i-VBL kufanele ifanele, ubumhlophe buzokwehla noma bube phuzi uma sebudlulele.Kunconywa ukuthi umthamo akufanele udlule u-0.5%.
