Imhlophe, iqaqambile, ilula kwaye icocekile, ifanekisela ubunyulu.
Abantu abaninzi bathanda izinto ezimhlophe, kwaye iimpahla zabathengi zihlala zenziwa zimhlophe. Ngokwesiqhelo, abantu abathenga izinto ezimhlophe okanye banxibe iimpahla ezimhlophe baya kulumkela ukuvumela umhlophe ufumane nayiphi na ibala. Kodwa kukho i-lyric othi, "kule minyaka ikwi-Universint iphela, uyala ngonaphakade." Nokuba umgudu owubekayo ukugcina ezi zinto ekungcoleni, baya kuncipha ngokuthe ngcembe batyhutyha ngokwabo. Kwiveki evekini, unyaka, okanye iminyaka emithathu, unxiba ityala lentloko emsebenzini, kwaye ihempe emhlophe ongakhange unxibile kwiwadi.
Ngapha koko, ityheli yeentsinga zempahla, izihlangu ze-eleustic, kunye neebhokisi zentloko zeplasitiki ziyimbonakaliso ye-polymer ukwaluphala, eyaziwa ngokuba yilow. Ukugqobhoza kubhekisele kwi-phenomenotion, ukuhlengahlengiswa, okanye ukudibanisa ukudibanisa iimolekyuli zemveliso ye-polymer ngexesha lokusetyenziswa, imitha ye-oxidation, okukhokelela ekumiselweni kwamaqela anemisebenzi emibi.
La maqela anemibala ahlala ehlala i-carbon carbon hands (c), amaqela e-carbonyl (c = o), amaqela emiliza (C = n), njalo njalo. Xa inani le-carbon yekharbon elihlanganisiweyo le-carbon lifikelela kwi-7-8, bahlala babonakala tyheli. Ngokwesiqhelo, xa uphawula ukuba iimveliso zepolymer ziqala ukujika ityheli, iqondo lokutyhobozela lihlala liye landa. Kungenxa yokuba ukonakaliswa kwe-polymers yindlela yokusabela, kwaye emva kokuba inkqubo yokuthambisa iqala, ukwahlukana kweemolekyuli kufana ne-domino, iyunithi nganye iwela enye.
Zininzi iindlela zokugcina izinto ezimhlophe. Ukongeza iTitanium Dioxide kunye ne-Agescecececceccent Whitinence Agents inokuthi iphucule ngokufanelekileyo isiphumo esimhlophe, kodwa ayinakuthintela umxholo otyhafileyo. Ukucothisa ityheli ye-polymers, ukuzinza ukukhanya, i-abssing, i-absching, iarhente zokunciphisa, njl njl. Ezi ntlobo zezongezo zinokufumana amandla aqhutywa yi-Ultraviolet ukukhanya kwelanga, ukuzisa i-polymer ibuyele kwilizwe elizinzileyo. Kwaye i-anti the the thermal oxidants inokuthi ifake i-radicals yasimahla eveliswe yi-oxidation, okanye ithintele ukonakaliswa kwemitya yepolymer yokuphelisa isikhonkwane se-Polymer Chain. Izixhobo zinemihla yobomi, kunye neezongezo nazo zinexesha lokuphila. Nangona ezongeziweyo zinokucothisa ngokufanelekileyo inqanaba le-polymer etyheli, bona baya kusilela xa besetyenziswa.
Ukongeza ukongeza ukongezwa, kunokwenzeka ukuthintela i-polymer etyheli kwezinye iinkalo. Umzekelo, ukunciphisa ukusetyenziswa kwezixhobo kubushushu obuphezulu kunye neemeko ezikhanyayo zangaphandle, kuyimfuneko ukufaka isibane esikhanyayo esikhawulezayo kwizixhobo xa bezisebenzisa ngaphandle. Ukungaphuzi akuchaphazeli inkangeleko, kodwa kukwasebenza njengophawu lokupheliswa kwentsebenzo yezinto ezibonakalayo okanye ukusilela! Xa izinto zokwakha zityhutyha, iindawo ezintsha kufuneka zitshintshwe ngokukhawuleza.
