Nubuhe buryo bwo kumenya umuringa wera

1. Reba ubukana: urwego rwo hejuru rwizaumuringaimitako, yoroshye imiterere na cyera kandi yoroshye hejuru.Uruganda rukora umuringa rufata imiringa yumuringa ya garama 60 nkurugero.Niba bakuweho amaboko, nta elastique ihari, kandi ubwiza bwabo ni 95%.Niba hari elastique nkeya, ubwiza ni 80% -90%;niba elastique ari nini, ubwiza buri munsi ya 70%.
2. Reba ibyatsi: gukata cyangwa kuzinga imitako y'umuringa kugirango urebe ibara ry'ibyatsi.Niba imitako yoroshye, ibyatsi birabyimbye kandi byoroshye, bitukura gato, kandi ibara ni 95%;niba bigoye kunama n'intoki, ibyatsi byera kandi byera, cyangwa umutuku muto, kandi ibara ni 90%;niba gukomera ari 90% Kinini, ibyatsi ni umutuku wijimye, umuhondo-umweru cyangwa imvi, kandi ubwiza ni 80%;niba ibyatsi bitoroshye, ibyatsi bitukura, umuhondo, khaki nandi mabara, kandi ubwiza ni 70%;niba lipstick ari umukara, Cyangwa umuhondo ufite umukara, kandi ubwiza buri munsi ya 60%.
3. Uburyo bwo kunama: gukubita no kugoreka n'intoki, ubuziranenge bworoshye kandi bworoshye, byoroshye kunama kandi ntibyoroshye kumeneka;kugabanura ubuziranenge buke biragoye, cyangwa birashobora kugorama, kandi bimwe ntibishobora no kugororwa n'intoki;umuringa wambaye umuringa uzavunika nyuma yo kunama cyangwa gukomanga inyundo inshuro nke;impimbano ntizashobora kwihanganira kunama kandi byoroshye kumeneka.Haba hari inyungu zubuzima zikomoka ku kwambara imitako ya magneti, akenshi ifite agaciro keza keza.
4. Uburyo bwo guta: imitako yumuringa wo murwego rwohejuru, yajugunywe ku kibaho, ntishobora gusimbuka hejuru, hari ijwi rya "pop";imitako yimpimbano cyangwa yujuje ubuziranenge iroroshye, yajugunywe ku kibaho kandi igatera hejuru cyane, ikora amajwi Ugereranije.Inama nziza zo gukorana imitako yumuringa harimo kugerageza tekinike zitandukanye no gutekereza kurangiza.Umuringa utavuwe ufite sheen ihindura ibara mugihe.Ibice bibiri byumuringa hamwe nu mugozi birashobora gukoreshwa mugukora impeta zishimishije, urunigi, impeta nimpeta.
Umuringa usukuye, nkuko izina ribivuga, ni umuringa urimo umuringa mwinshi, kubera ko ibara ari umutuku-umutuku, uzwi kandi nk'umuringa utukura.Ibice nyamukuru ni umuringa nifeza, nibirimo ni 99.5-99.95%.Ibintu nyamukuru byanduye: fosifore, bismuth, antimoni, arsenic, fer, nikel, gurş, amabati, sulfure, zinc, ogisijeni, nibindi.
