Empilweni yansuku zonke, wake wazibuza ukuthi kungani ezinye izihlanzi zokuwasha izingubo zingenza izingubo ezimhlophe "zibenyezele" ngemva kokuzigeza, njengokungathi zivuselelwe? Lokhu kungenxa yezinto zokusetshenziswa zamakhemikhali ezibizwa ngokuthi "i-optical brightener agent CBS-X." Le kristalu emhlophe ebonakala ijwayelekile empeleni "iyimpuphu yomlingo" ebalulekile embonini yamakhemikhali yansuku zonke. Namuhla, isibe umkhiqizo oyinhloko emkhakheni wokukhiqiza oluhlaza ngenxa yokusebenza kwayo okuhle kakhulu kwemvelo.

Kuyinii-optical brightener CBS-X?

I-CBS-X, eyaziwa nangokuthi i-disodium stilbene-biphenyl disulfonate, iyisibanisi sokukhanya se-stilbene-biphenyl. Isimiso sayo sokusebenza akuyona "i-bleaching" yendabuko, kodwa kunalokho imunca ukukhanya okungabonakali kwe-ultraviolet bese ikuguqula kube ukukhanya okubonakalayo okuthambile okuluhlaza okwesibhakabhaka. Lokhu kukhanya okuluhlaza okwesibhakabhaka kuhambisana nokukhanya okuphuzi kwendwangu ngokwayo, kudala ubumhlophe obukhulu kakhulu nokukhanya, okwenza izingubo ezindala zibukeke "zintsha embonini".

Ngokombono ongokwenyama,I-CBS-Xngokuvamile kuvela njengempuphu noma ama-granule acwebezelayo aphuzi-luhlaza okwesibhakabhaka anokuncibilika kwamanzi okuhle kakhulu: ukuncibilika kwawo emanzini abandayo ku-25°C kungafinyelela ku-25g/L, kuyilapho ukuncibilika kwawo emanzini ashisayo ku-95°C kukhuphuka kufike ku-300g/L, okwenza kube lula ukuzivumelanisa nezimo ezahlukahlukene zokuwasha njengokuwasha okubandayo nokushisayo.

“Umfundi ovelele” phakathi kwezinsipho

Embonini yensipho yokuwasha izingubo, i-CBS-X idunyiswa njengenye “yezikhanyisi zokukhanya ezinhle kakhulu.” Ukuthandwa kwayo kuvela ngokuyinhloko ezinzuzweni ezilandelayo eziyinhloko:

1. Isilinganiso esiphansi, ukusebenza kahle okuphezulu: I-CBS-X inamandla amakhulu kakhulu okukhanya. Ukwengeza u-0.05%-0.2% kuphela emshinini wokuwasha izingubo noma ku-powder kufeza umphumela obalulekile wokwenza mhlophe. Uma kuqhathaniswa nama-ejenti e-stilbene triazine optical brightener endabuko, ukusebenza kwayo okuphezulu kusho izindleko eziphansi kanye nokusetshenziswa kwezinsizakusebenza.

2. Uzinzile kakhulu: Lo mkhiqizo ubonisa ukumelana okuhle kakhulu ne-chlorine bleach kanye nama-acid kanye nama-alkali, uhlala uzinzile ngisho nasezindaweni zokumhlophe eziqukethe i-sodium hypochlorite, okwenza kube yisibani esimelana ne-bleach. Lokhu kusho ukuthi ngesikhathi sokuwasha okuphindaphindiwe, ungakhanyisa izingubo ngaphandle kokubangela ukuphuzi noma ukushintsha kombala.

3. Ukusondelana kwefayibha okubanzi: I-CBS-X inomphumela omuhle wokwenza mhlophe kumafayibha e-cellulosic (njengokotini), ama-polyamides (njenge-nylon), kanye namafayibha e-protein (njengoboya nesilika) kokubili ekushiseni kwegumbi kanye nasekushiseni okuphezulu, okwenza kube nokuguquguquka okukhulu.

Amaphuzu Avelele: Ukusebenza Ndawonye Ukuze Kube Nobuhle Bemvelo

Ngenxa yokukhathazeka kwabathengi mayelana nobungane bemvelo bezinto ezikhanyisa ukukhanya, i-CBS-X, enezakhi zayo eziluhlaza, ibeke uphawu olusha embonini.

Ibola kalula futhi ibuyele emvelweni,
okukhiqizwe ngesimanjeI-CBS-Xinezinzuzo ezinhle kakhulu zemvelo. Ibola kalula futhi ayingcolisi imvelo ngesikhathi isetshenziswa, ihlangabezana ngokugcwele nezidingo eziphuthumayo zomphakathi wanamuhla zemikhiqizo enobungani nemvelo kanye nemibono yentuthuko esimeme. Eminye imikhiqizo ichazwa ngokuqondile njengemikhiqizo enobungani nemvelo ngenxa yobukhulu bayo obukhulu obumaphakathi bezinhlayiya.

Ukuphepha kwe-CBS-X sekuyisikhathi eside kuqashelwa emhlabeni jikelele, ngokusho kwezitifiketi zomhlaba wonke ezigunyaziwe
. Iphasise izitifiketi ezivela ezikhungweni zokuhlola eShayina, e-United States, eJapane, kanye nase-European Union. I-China Cleaning Products Industry Association iphinde yashicilela izihloko ngeziteshi ezisemthethweni ezinikeza incazelo eningiliziwe ngokuphepha kwama-optical brighteners.

Ayinazo izinto ezingavunyelwe, ivikela impilo yakho:

I-CBS-XAma-molecule awana-chlorine futhi awabangeli umdlavuza. Izinkomba zekhwalithi yayo zilawulwa ngokuqinile ngokuqukethwe kwama-aromatic amine ayingozi kanye nezinsimbi ezisindayo, okuqinisekisa ukuphepha kwabantu ngaphansi komthamo onconywayo kanye nokusetshenziswa okuvamile. Ivunyelwe ngisho nokuxhumana nokudla, okubonisa iphrofayili yayo yokuphepha enhle kakhulu.

Ngaphezu nje "kokwenza mhlophe", kuyisinqumo esiqhubekayo.

Bephendula ukukhathazeka okuphakanyiswe abanye abathengi mayelana nokuphepha kwama-optical brighteners, ochwepheshe bemboni banikeze izimpendulo ezicacile. Kusukela ngo-2008, izinga lomkhakha i-QB/T 2953-2008 labala ngokucacile ama-stilbene biphenyls (CBS-X) njengesigaba esivunyelwe ukusetshenziswa kuma-detergents okuwasha. Ngaphezu kwalokho, umbiko wokuhlola ubungozi ovela kwi-European Detergents Association (AISE) ukhombisa nokuthi i-CBS-X esetshenziswa kuma-detergents ngeke ibangele imiphumela emibi empilweni yabantu noma emvelweni.

Ngokombono wezemvelo, ukusebenza kahle kwe-CBS-X kusho umthamo ophansi—kudingeka inani elincane kakhulu ukuze kufezwe umphumela ofiselekayo, okunciphisa ngqo ukusetshenziswa kwezinto zokusetshenziswa zamakhemikhali kanye nomthelela wezemvelo wezinqubo zokukhiqiza zezimboni.

Umbono Wemakethe: I-Green Wave Ikhuthaza Ukukhula

Njengoba abathengi bomhlaba wonke beqhubeka befuna “ukuhlanzeka” kanye “nobungani bemvelo,” imakethe ye-optical brightener ikhula njalo. Ngokusho kwedatha yocwaningo lwemakethe, ubukhulu bemakethe ye-optical brightener CBS-X buzuza ngokufunwa okukhulu okuvela ezimbonini zezindwangu kanye nezokuhlanza, futhi amathuba ayo ayathembisa.

Inkampani yethu igxile ekuthumeleni kwamanye amazwe ama-ejenti okukhanyisa ama-optical futhi inolwazi olungaphezu kweminyaka eyishumi. Uma unemibuzo mayelanaama-ejenti okukhanyisa okukhanya,sicela uzizwe ukhululekileXhumana nathi.
