Igishushanyo kirambuye

Bisobanura iki "UNC"?

UNC yerekeza ku nsanganyamatsiko ifatanye muri Amerika ya Amerika isanga urukurikirane rw'umuyaga (hatoranijwe umugozi wo hanze wa radiyo).

Ni ubuhe buvuzi bwirabura?

Umukara wirabura, uburyo busanzwe bwo kuvura imiti. Oxide yumukara nuburyo busanzwe bwo kuvura imiti. Ihame nuwatangara firime yamarambi hejuru yicyuma kugirango igabanye umwuka kandi igere ku ntego yo gukumira ingera. Iyo ibisabwa bitagaragara ntabwo ari byinshi, umukarakazi birashobora gukoreshwa, kandi ubuso bwibice by'icyuma burahanagura, nabyo byitwa ubururu.

Uburyo bukoreshwa muburyo bwirabura burimo gukuramo alkaline gakondo hamwe nubushyuhe bwicyumba bubaho nyuma. Ariko, inzira yo gucana mubushyuhe bwicyumba ntabwo ari byiza cyane kuri sitbon nkeya. Alkaline brackening iragabanijwe, kandi hariho itandukaniro riri hagati yo gucana no kurabira kabiri. Ibigize byinshi byamazi Blackening ni sodium hydroxide na sodium nitrite. Itandukaniro ryubushyuhe risabwa kugirango urumuri rutari runini, kandi ubuso bwiza burashobora kuboneka hagati ya 135-155 ° C, ariko igihe gikenewe ni kirekire.
