Chifukwa chiyani Galasi ili ndi mitundu yosiyana?

Magalasi abwinobwino amapangidwa kuchokera ku mchenga wa quartz, koloko ndi miyala yamchere, posungunula pamodzi.Ndi mtundu wa silicate osakaniza a madzimadzi mapangidwe.Pachiyambi, galasi mankhwala ndi mtundu tinthu tating'ono ting'ono ndi kuwonekera osauka.Mtunduwu sunawonjezedwe ndi ntchito zopangira, zenizeni ndikuti zopangira sizili zoyera, ndipo zimasakanizidwa ndi zonyansa.Panthawiyo, zinthu zamagalasi achikuda zimagwiritsidwa ntchito kukongoletsa, zimasiyana kwambiri kuposa pano.

Pambuyo pa kafukufuku, anthu adapeza kuti ngati awonjezeredwa 0.4% ~ 0.7% utoto muzopangira, galasi lidzakhala ndi mtundu.Nthawi zambiri colorant ndi metallic oxide, popeza zitsulo zilizonse zimakhala ndi mawonekedwe awoawo, ndiye kuti oxidi wachitsulo wosiyanasiyana amawonetsa mitundu yosiyanasiyana pagalasi.Mwachitsanzo, galasi yokhala ndi Cr2O3 idzawonetsa mtundu wobiriwira, ndi MnO2 idzawonetsa mtundu wofiirira, ndi Co2O3 idzawonetsa mtundu wabuluu.

Ndipotu, mtundu wa galasi sunakhazikitsidwe pamtundu.Kupyolera mu kusintha kutentha smelting, kusintha valence wa chinthu, ndiye akanatha kupanga galasi ndi mitundu yosiyanasiyana.Mwachitsanzo Cuprum mu galasi, ngati analipo ndi mkulu valence mkuwa okusayidi mu galasi, ndi buluu wobiriwira mtundu, koma ngati analipo ndi otsika valence Cu2O, izo kusonyeza wofiira.

Tsopano, anthu amagwiritsa ntchito oxidate osowa padziko lapansi ngati utoto kuti apange magalasi amtundu wapamwamba kwambiri.Galasi yokhala ndi zinthu zapadziko lapansi zomwe siziwoneka bwino zimawonetsa mtundu wowala komanso kunyezimira, ngakhale kusintha mtundu ndi kuwala kosiyanasiyana kwadzuwa.Pogwiritsa ntchito galasi lokoma mtima limeneli kupanga mazenera ndi zitseko, m'nyumbamo amatha kusunga kuwala, osagwiritsa ntchito nsalu yotchinga kupeŵa kuwala kwa dzuŵa, ndiyeno anthu ankawatcha kuti nsalu yotchinga yokha.
