Optical Brighteners dzave dzichishandiswa pamwe chete nedetergent kubvira muna 1940. Pasinei nekuti dzine dose shoma mu detergent, dzinoita kuti dzichene uye dzipenye, zvichiita kuti dzive chinhu chinonyanya kufarirwa muindasitiri ye detergent.

Zvichienderana nenhamba dzisina kukwana,40% yezvigadzirwa zveOptical brightener pasi roseparizvino iri kushandiswa muchikamu chekuchenesa sipo.

Chinyorwa chino chinopa pfupiso pfupi yeOptical Brighteners, kusanganisira tsananguro yavo, nzira yekuchenesesa, kugadzirwa uye kushandiswa, chiyero chinokurudzirwa, uye chinonyanya kukosha, kuchengetedzeka kwavo pakushandiswa—chinhu chikuru chinonetsa vatengi pasi rese.

1. NdezvipiZvivhenekeri zveOptical?

Optical Brighteners rudzi rweOptical dye. Pasi pemwaranzi ye ultraviolet (UV), vanoburitsa chiedza chebhuruu ne violet chinoenderana nechiedza yeyero pamusoro pe substrate, nokudaro vachiita kuti chichene.

Inozivikanwawo sezvinovhenekesa zvemaziso or madhayi machena eOptical, vanoshandisa simba rekuwedzera ruvara rweoptical kuti vachenese, vapenye uye vawedzere kupenya kwezvinhu zvichena kana zvine ruvara rwakajeka zvakaita semachira, bepa, uye mapurasitiki.

2. Nzira yekuchenesa Magirazi eOptical

Sezvinoratidzwa netsananguro yavo, nzira yekuchenesesa yeOptical Brighteners ndeiyi inotevera:

Kana vakaiswa pachiedza chezuva (chine chiedza cheUV), vanotora chiedza cheUV chine urefu hwemafungu e340 ~ 380nm uye vanoburitsa chiedza cheOptical muchikamu chinoonekwa chebhuruu-violet (410 ~ 460nm). Chiedza ichi chinobuda chinosanganiswa nechiedza cheyero chiri pachigadziko kuti chibudise mhedzisiro yakajeka yekuchena.

Kuratidzwa kwechiedza chinoonekwa nechinhu chakavhenekerwa kunowedzera, izvo zvinoita kuti chichena uye kupenya kwechinhu chacho zviwedzere zvakanyanya.

3. Kushandiswa kweOptical Brighteners

Optical Brighteners inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana, kusanganisira machira, kugadzira mapepa, sipo, mapurasitiki, machira ekuputira, inki, dehwe, anti-counterfeiting, uye laser detection. Kugoverwa kwekushandiswa kwepasi rose nemaindasitiri kunoratidzwa mutafura iri pazasi:

4. Sei Uchifanira Kuwedzera Magirazi Echiedza Mumadhishi Ekuchenesa?

(1) Kuvandudza Kushanda Kwekugeza

Machira machena kana kuti akajeka akagadzirwa neshinda dzechisikigo uye dzekugadzira anowanzova eyero uye anotaridzika seakasakara mushure mekushandiswa nekusukwa kakawanda. Kana machira akasukwa, maOptical Brighteners ari mu sipo anonamira pamusoro pejira, ochenesa uye anopenya zvinhu zvakasukwa, achidzorera machira akacheneruka, akareruka kutaridzika kwakachena, kwakajeka uye kwakafanana nekwetsva. Izvizvinoonekwa zvinosimudzira mashandiro ekuwachayechigadzirwa chesipo.

(2) Kuvandudza Chitarisiko cheChigadzirwa cheSipo

Optical Brighteners inonyatso wedzera kuchena kwe sipo yekuwachisa yakagadzirwa nehupfu kana sipo,kuwedzera kutaridzika kwezvigadzirwa zvesipo uye kuwedzera kunaka kwechigadzirwa chazvo.

5. Zvinovhenekesa Maziso Zvinowanikwa Kazhinji zveMafuta

Kusarudzwa kweOptical Brighteners kwakakosha pakugadzira sipo. Zvichienderana nekushandiswa kwemakumi emakore, DSD acid bis-triazine uye distyryl biphenyl Optical Brighteners dzinopa kushanda kwakanaka.

Pakati peizvi,CI Optical Brightener 351uyeCI Optical Brightener 71ndiwo marudzi anoshandiswa zvakanyanya pasi rose—anozivikanwawo seOptical Brightener CBS uye Optical Brightener CXT, mhando mbiri huru dzakagamuchirwa zvakanyanya muindasitiri yekuchenesa sipo muChina uye dzinozivikanwa pasi rose.

6. Chiyero Chinokurudzirwa ChemaOptical Brighteners MumaDetergents

Zvakawanda hazvisi naniKana zvasvika pachiyero cheOptical Brighteners mumasiponji. Huwandu hwakakwana hunoenderana nezvinhu zvakaita sekugadzirwa kwesipo, mashandisirwo aunoda, uye rudzi rweOptical brightener.

Kupenya kwechiedza cheyero pamachira akagezwa kunogumira, saka huwandu hwechiedza chebhuruu-violet chinodiwa kuti chisapararire hunodererawo. Sezvo kuwanda kweOptical Brighteners pajira kuchiwedzera, kupenya kwechiedza chebhuruu-violet chinobuda kunowedzera, zvichiita kuti jira riwedzere kuchena.

Kana huwandu hwacho hwasvika padanho rakanaka, simba rechiedza chebhuruu-violet chinobuda rinonyatso dzivirira chiedza chechero pajira—iyi ndiyo poindi yepamusoro yekuchenesesaKuwedzera mwero wemushonga kuchaita kuti kuchena kuchene.

Hunhu uhwu hunosimbisa kukosha kwekudzora dosi nemazvo. MuEurope neUnited States, dosi inokurudzirwa yeOptical Brighteners mu detergents inosiyana.kubva pa0.05% kusvika pa0.5%.

7. Kuchengetedzwa kweMagirazi Echiedza Pakushandisa Sipo

Kuchengetedzeka kweOptical Brighteners chinhu chinonyanya kutyiwa nevatengi, uye chinotokonzera kusava nechokwadi uye kuzvidya mwoyo zvisina kufanira. Kune Optical Brightener CBS neCXT—mhando mbiri dzinonyanya kushandiswa muindasitiri yekuchenesa—nyanzvi dzezvechepfu nedzezvakatipoteredza pasi rose dzakaita zvidzidzo zvesainzi zvakasimba pamhuka dzemurabhoritari nevanhu vanozvipira kuti vaongorore kuchengetedzeka kwavo.

Zvidzidzo izvi zvinofukidza chepfu yakakomba, chepfu yeganda, kushatirwa, kunzwa kweganda, chepfu yegenotoxicity, chepfu inodzokororwa, teratogenicity, kenza, kuunganidzwa kwayo mumuviri, pamwe nekuwanda kwayo munzizi nevhu. Pamusoro pezvo, kuenzanisa uye kubvisa kwakaitwa pazviitiko zvinogona kuitika kuvanhu, huwandu hwehutachiona, uye miganhu yekusvibiswa.

Mhedzisiro yacho yakajeka uye ine musoro:

1. Ruzivo rwazvino kubva kuEuropean Chemicals Agency (ECHA) runosimbisa kuti Optical Brighteners inoshandiswa pakuchenesakwete zvinhu zvePBT (Persistent, Bioaccumulative, Toxic) kana vPvB (Very Persistent, very Bioaccumulative).

2. Magirazi eOptical ndiwohazvina kubatanidzwapane runyorwa rwemadhayi akarambidzwa akabudiswa neEuropean Union neInternational Association for Research and Testing in the Field of Textile Ecology (Oeko-Tex).

3.European Chemical Industry Council (CEFIC) pamwe nemasangano epasi rose e sipo ne detergent vanosimbisa kuti Optical Brighteners yekushandisa detergent dzakachengeteka uyehazvikuvadzi hutano hwevanhu kana nharaunda.

4. Sangano reJapan Sipo neSipo (JSDA) rinogumisa kuti Optical Brighteners yekushandisa sipo inenjodzi yakaderera zvikurukuhutano hwevanhu nenharaunda.

Ongororo iyi inopa kunzwisisa kwakakwana uye kwakarurama kweOptical Brighteners uye mashandisirwo adzo mu sipo. Kana muine mibvunzo nezvezvigadzirwa zvedu zveOptical brightener, ndapota inzwa wakasununguka kupindura.taura nesuchero nguva—tinopa mhinduro dzemhando yepamusoro, dzinoenderana nezvinodiwa nemushonga wedhishi.
