Iphepha lamahhala likayinki lokushintsha iphepha elivamile

A emisha kwezobuchwepheshe kungasiza ukubhekana nezinkinga ezandayo endaweni kanye nokusimama kwezinsiza. Iphepha, elakhiwe eNyuvesi yaseCalifornia, e-Riverside, lingabhalwa futhi lisulwe izikhathi eziningi.

Leli phepha, ngendlela yengilazi noma ifilimu yepulasitiki, lisebenzisa odayi be-redox. Udayi wenza “i-imaging layer” yephepha, izithombe nombhalo, futhi ukukhanya kwe-UV kuvula udayi ngaphandle kodayi owenza umbhalo noma izithombe ephepheni. Ukukhanya kwe-UV kunciphisa udayi esimweni sawo sokungabi nambala ukuze okungabonwa kuphela izithombe noma umbhalo okhiqizwayo. Noma yini ebhaliwe ihlala kuze kube yizinsuku ezi-3.

Yonke into isulwa ngokushisisa ngo-115 C, lapho “ukukhishwa kabusha kwe-oxidation kadayi oncishisiwe kubuyisela umbala wokuqala.” Ukusula kungaqedwa ngaphansi kwemizuzu eyi-10.

Ngale ndlela, leli phepha lingabhalwa, lisulwe, bese libhalwa kabusha izikhathi ezingaphezu kwezingu-20 “ngaphandle kokulahlekelwa okukhulu ngokuqhathaniswa noma ukulungiswa.” Iphepha lingaba ngemibala emithathu: eluhlaza okwesibhakabhaka, obomvu, noluhlaza.

Ngokuvumelana ne Yadong Yin, uprofesa wesayensi yokuthakwa kwamakhemikhali owasiza ekuholeni ucwaningo lwalesi senzakalo, “leli phepha elibhalwe kabusha alidingi o-inki abengeziwe ukuze linyatheliswe, okulenza libe namandla ngokwezomnotho nangokwemvelo. Imelela iphepha elikhangayo elivamile ekuhlangabezaneni nezidingo ezikhulayo zomhlaba wonke zokusimama nokongiwa kwemvelo. " Lokhu kuqanjwa kabusha kunganciphisa kakhulu ukusetshenziswa kwephepha, esinye sezithembiso zenkathi entsha yedijithali.

Ngokusho the I-WWF, iphepha likhiqizwa cishe amathani ayizigidi ezingu-400 (amathani ayizigidi ezingu-362) ngonyaka futhi liyakhuphuka.
