Kwimimandla yemveliso kunye nesayensi yezaziseko, ukufuna ukwandisa isibheno kunye nokusebenza kweemveliso ezingapheli. Inqaku elinye elifumana itrasti enkulu kukusetyenziswa kwabakhethiweyo, ngakumbi kwiiplastiki. Nangona kunjalo, umbuzo oqhelekileyo ophakamayo kukuba ingaba abakhali abakhethiweyo bayalingana nokubhloka. Eli nqaku lijolise ekuqondeni la magama kwaye iphonononge imisebenzi, ukusetyenziswa kwawo, kunye nolwahluko.
Yintoni eyona qhina?
Abakhethiweyo, ekwabizwa ngokuba zii-Agement Shiten Whitering (i-FWA), ziyimigaqo-nkqubo e-istraviolet (uv) ukukhanya kwaye iphinde ikhuphe ukukhanya okubonakalayo. Le nkqubo yenza ukuba izinto zibonakale zimhlophe kwaye ziqaqambe kwiliso lomntu. Abakhethiweyo abakhethiweyo basetyenziswa kuluhlu olubanzi lwamashishini, kubandakanya ii-scricts, iicoci kunye neplastiki.
Kwimeko yePlastiki, i-Sketical Bible yongezwa ngexesha lenkqubo yokuphucula isibongozo esibonakalayo semveliso yokugqibela. Ziluncedo ngokukhethekileyo ekwenzeni izinto zeplastiki zijongeka kwaye zithandabuze ngakumbi, zibuyekeza nakuphi na ukuhlambalaza okanye ukungcola okunokwenzeka ngokuhamba kwexesha.
Basebenza njani abathi basebenza?
Inzululwazi yangemva abahlonelwayo ineengcambu zayo ekufumaneni. Xa ukukhanya kwe-ultraviolet kunamathela kumphezulu weemveliso zeplastiki eziqukethe abahloli, i-computer ifumana ukukhanya kwe-ultraviolet kwaye iphinde ikhuphe ukukhanya okubonakalayo. Olu lwazi luhlaza okwesibhakabhaka luyayikhupha nayiphi na i-tint yetyheli, yenza iplastiki ijongeke imhlophe kwaye iqhubele phambili.
Ukusebenza kweAbakhethiweyoKuxhomekeka kwizinto ezininzi, kubandakanya uhlobo lweplastiki, uxinzelelo lweqonga, kunye nokuqulunqa okuthile kwequalm. Abakhethiweyo abaqhelekileyo abakhethiweyo abasetyenziswa kwiiplastiki zibandakanya ii-stilivatives, iihemari kunye ne-Benzozazines.
Ukusetyenziswa kweearhente ze-fluoresting ze-fluoresting kwiplastiki
Abakhethiweyo abakhethiweyo basetyenziswa ngokubanzi kwiimveliso zeplastiki, kubandakanya:
I-1. Izinto zokupakisha: Yenza ukupakisha unomdla wokubona kwaye uphucule imbonakalo yemveliso ngaphakathi.
2. Izinto zasekhaya: ezinje ngeziqulatho, izitya, ifenitshala, njl. Njl.
I-3. Inxalenye ezenzekelayo: Phinda uphucule i-aesthetics yengaphakathi kunye nengaphandle.
4. I-Electronikhi: Qinisekisa ukuba ube ngumlingane, wale mihla kwizindlu kunye nezinye izinto.
Ngaba abakhethiweyo abakhethiweyo ngokufanayo njengokuqaqanjelwa?
Impendulo emfutshane ayikho; Abakhethiweyo kwaye babyach ayifani. Ngelixa zombini zisetyenziselwa ukuphucula ukubonakala kwempahla, zisebenza ngeendlela ezahlukeneyo ngokupheleleyo kwaye zisebenzele iinjongo ezahlukeneyo.
Yintoni i-bleach?
I-Bleach yicandelo lekhemikhali elisetyenziselwa ukubulala iintsholongwane kunye neepropathi ezimhlophe. Eyona ntlobo ixhaphakileyo ye-blorine ibraloch bleach (i-sodium hypochlorite) kunye ne-oxygen blicle (i-hydrogen peroxide). I-Bleach isebenza ngokwaphula amaqhina emichiza phakathi kwebala kunye ne-pigments, ukususa umbala kwizixhobo.
Umahluko ophambili phakathi kwabakhethiweyo kunye ne-bleach
I-1. I-Mechasm yeNkqubo:
-Akukrakra ii-Optical brawns
-Bilech: Susa umbala kwizixhobo ngokuqhekeza ngamachiza kunye ne-pigments.
2. Injongo:
-I-Fluoresting Whoshers I-Agevers ye-Sweorening: Isetyenziselwa ngokuyintloko ukonyusa isibongozo esibonakalayo sezinto ngokuzithanga ngokuzithandela ngokwenza ukuba babonakale ukucoceka kwaye bavuselele ngakumbi.
-Bilech: isetyenziselwa ukucoca, ukubulala kunye nokususwa kwendawo.
3. Isicelo:
-I-Fluoresting Whoiteling Mbeeling:
-Belech: isetyenziswe kwiimveliso zokucoca amakhaya, iicoci zokuhlamba iimpahla kunye neecocieners.
4. Ubume bemichiza:
-I-Fluoresting Whoshers I-Agers: Ihlala iMida ye-Organic efana ne-stillene desvivenitives, iihemari kunye ne-Benzoxazines.
-Bilech: I-Inorganic Pocends efana neSodium Hypochlorite (i-chlorine bluach) okanye imijikelezo ye-organic) okanye imijikelezo ye-organic efana ne-hydrogen peroxide (i-oxygen bleach).
Ukuqwalaselwa nokuqwalaselwa kwendalo
Abakhethiweyokunye ne-Nationali nganye banokukhuseleka kwabo nokhuseleko lokusingqongileyo. Abakhethiweyo abakhethiweyo bathathelwa ingqalelo ukuba bakhuseleke kwiimveliso zabathengi, kodwa kukho izinto ezixhalabisayo malunga nokuzimela kwabo kwindalo kunye neziphumo ezinokubakho kubomi base-Aquatic. I-Bleach, ngakumbi i-chlorine iblech, iyonakalisa kwaye ivelise iimveliso eziyingozi ezinjengeedioxin, eziyingozi kwimpilo yabantu kunye nokusingqongileyo.
Ukuququmbela
Nangona abakhethiweyo abakhethiweyo kunye ne-bleach ingabonakala ngathi ngenxa yeziphumo zabo ezimhlophe, iindlela zabo, iinjongo, kunye nezicelo zahlukile ngokusisiseko. Abakhethiweyo abakhethiweyo ziikhonkco ezikhethekileyo ezisetyenziselwa ukonyusa isibongozo esibonakalayo seplastiki kunye nezinye izinto ngokuzithandela zibonakale zimhlophe kwaye ziqaqambile. Ngokwahlukileyo koko, iblech sisicoci esinamandla esisetyenziselwa ukususa amabala kunye nentsholongwane.
Ukuqonda lo mahluko kubalulekile kubavelisi, abathengi, kunye nabani na obandakanyekayo kwiSayensi yeZakhiwo okanye uphuhliso lwemveliso. Ngokukhetha uluhlu oluchanekileyo lwesicelo esifanelekileyo, sinokufikelela kwiziphumo zobuhle obufunekayo kunye neziphumo ezisebenzayo ngelixa kuncitshiswa iimpembelelo ezimbi zempilo kunye nokusingqongileyo.
