Kodi mungapewe bwanji bolodi la njovu kuti lisakhale lachikasu?

Mabokosi amitundu omwe amagwiritsidwa ntchito poyika zinthu ndi mabokosi oyika zinthu zosiyanasiyana amapangidwa makamaka ndimatabwa a minyanga ya njovu . Pambuyo slitting, kusindikiza ndi processing wotsatira, amakhala mankhwala ma CD bokosi lathu.

Masiku ano, pamene zosangalatsa zakuthupi zikuchulukirachulukira, anthu ali ndi zofunikira zapamwamba komanso zapamwamba za khalidwe la makatoni. Gulu la Ivory (lomwe limadziwikanso kuti makatoni oyera okutidwa kapenaFBB ) ndi katundu wapamwamba kwambiri, ndipo maonekedwe ake okongola akhalanso cholinga cha anthu. Komabe, chikasu chodabwitsa cha pepala lopaka bolodi loyera pakugwiritsa ntchito kumakhudza kwambiri mawonekedwe akunja. Kuyera kwa makatoni oyera kumatanthawuza chodabwitsa kuti kuyera kwa mankhwalawo kudzachepa pang'onopang'ono pakatha nthawi yosungirako kapena kuyatsa dzuwa.

Zotsatira zaposachedwa zafukufuku zikuwonetsa kuti chodabwitsa cha chikasu ndikuti zinthu zapabokosi lopindika zimakhudzidwa ndi mpweya mumlengalenga, zomwe zimasintha mawonekedwe azinthu zam'mwamba, potero zimakhudza momwe anthu amawonera. Kuchuluka kwa okosijeni kumatsimikizira kuopsa kwa chikasu.

Zomwe zimakhudza chikasu chamakatoni oyera makamaka zikuphatikizapo mbali zotsatirazi: TACHIMATA bolodi loyera m'munsi pepala, fulorosenti whitening wothandizila, mtundu pigment, ❖ kuyanika zomatira, etc. Kupititsa patsogolo zikhalidwe za kupanga mapepala m'munsi, kusankha apamwamba fulorosenti whitening wothandizira, inki mtundu, kusintha mlingo mulingo woyenera kwambiri, ndi mwasayansi. kudziwa bwino kuphatikiza zomatira, amene angathe kuchepetsa chikasu chodabwitsa TACHIMATA pepala loyera; Zowonjezera, monga ma nano-silicon-based oxides, mankhwala osokoneza bongo monga UV absorbers ndi antioxidants, amachepetsanso zochitika zachikasu za pepala loyera loyera; kulimbikitsa kuwongolera kupanga kwa pepala loyera komanso kupewa mbali zonse za ma CD ndi kusungirako ndi njira yabwino yothetsera chikasu cha makatoni oyera.

Sinthani njira zonse zomwe zikukhudzidwa, sinthani ndikuwongolera magwiridwe antchito, ndipo mtundu wa khadi loyera lokutidwa udzakhala wapamwamba kwambiri.
