Olee otú etch osisi?

Iji etch osisi hydrogen peroxide na citric acid gafere ngwa ngwa, i nwere ike iji abụọ containers. Nanị tinye nta ike ahịhịa n'ime ibu akpa na wụsa mmiri ọkụ n'ime ya. Nke a ga-adị n'elu ma welie usoro.

Etching iba ke p-D hydrogen peroxide na-rụrụ dị ka ndị a: ụgwọ enịm ke a ahịhịa n'akụkụ nke tracks na-adọta ruo ire ere ngwaahịa na-adị mfe, zie na ala nke akpa. Iji mmeghachi omume bụ ihe edo ngwọta kwesịrị site n'oge ruo n'oge na nwuo ubé. The dum usoro na-ewe ihe na-erughị 10 nkeji.
