Iinkcukacha zeMveliso:

Ukukhanyisa okubonakalayoyiteknoloji yokwenza mhlophe emzimbeni eyamkelwe ngokubanzi kumashishini anamhlanje, kwayeIiarhente ze-Optical Brightener(OBAs) zisebenza njengeekhemikhali ezisebenzayo eziphambili ukufezekisa le mpembelelo. Ezi khompawundi zikhethekileyo ze-organic, ezi zibizwa ngokuba zii-fluorescent whitening agents, ziye zaba zezongezo ezibalulekileyo kwimpahla yokulahlwa, ekwenzeni amaphepha, kwiisepha, kwiiplastiki nakwiingubo, ngenxa yeempawu zazo ezizodwa zokukhanya kunye nokusebenza okuthembekileyo.

Iimbonakalo:

1. Umgubo otyheli.
2. Ukukhanyisa umqhaphu, uboya, isilika, intlama.
3.Umgangatho ophezulu weendlela ezahlukeneyo zokupakisha.
4. Iphepha elikhanyayo nelinamandla, umbala welaphu lomqhaphu.

Isicelo:

Ngeentlobo ezahlukeneyo ezithengiswayo, iiarhente ezahlukeneyo zokukhanyisa i-optical zenzelwe ukulingana nezinto ezithile eziluhlaza kunye neendawo zemveliso. Phakathi kwazo, i-Optical Brightener Agent BBU ivelele njengemveliso ye-stilbene tetrasulfonic acid yakudala, ethandwa kakhulu kumashishini elaphu kunye namaphepha kwihlabathi liphela. Ngokwekhemikhali, yi-anionic brightener enyibilikayo emanzini eneempawu ezintle kakhulu. Iqhayisa ngokunyibilika kwamanzi okugqwesileyo: malunga ne-150 grams inganyibilika kwilitha enye yamanzi abandayo, kwaye ukunyibilika kunyuka ukuya kwi-300 grams ngelitha emanzini abilayo. Ngaphandle koko, i-BBU ibonisa ukunyamezela okukhulu kumanzi aqinileyo; i-calcium kunye ne-magnesium ions emanzini aziyi kuphazamisa ukusebenza kwayo kokumhlophe. Ikwahambelana kakuhle neearhente zokumhlophe eziqhelekileyo kunye neearhente zokunciphisa ezisetyenziswa kwimveliso. Ngokuphathelele iimeko zokusetyenziswa, inikezela ngesiphumo esifanelekileyo sokumhlophe kwiindawo ze-alkaline ezinexabiso le-pH elingaphezulu kwe-7, ngelixa ukumelana kwayo ne-asidi kuphakathi, ngoko ke ayikhuthazwa kwiimeko zokucubungula i-asidi enamandla.
