Gilashin kwalabe wani akwati ne da ake amfani da shi sosai wanda ke taka rawar da ba za a iya maye gurbinsa ba a fannoni da yawa kamar abinci, magunguna, kayan kwalliya, da barasa. Launi, nuna gaskiya, da sauran halayen kwalabe na gilashin su ma suna ɗaya daga cikin dalilan da ya sa za a iya amfani da su sosai. Koyaya, wasu kwalabe masu launi na musamman suna buƙatar maganin canza launi don yin. Don haka, waɗanne hanyoyi ne masu kera kwalban gilashi suke amfani da su lokacin da suke canza kwalaben gilashi?
1. Yin amfani da karfe oxides don canza launi
Hanyar sinadarai ta amfani da mahadi masu ɗauke da ions ƙarfe don samar da wani Layer na fim ɗin ƙarfe oxide mai kauri daga micrometers da yawa zuwa ɗaruruwan micrometers a saman gilashin, wanda ke samar da ɗaruruwan launuka na gilashi, ana kiransa vacuum deposition. A cikin wannan hanya, zaɓin oxides yana da mahimmanci sosai saboda ions ƙarfe na iya ɗaukar igiyoyin lantarki na musamman na musamman, yana haifar da launuka na musamman. Wasu oxides da aka saba amfani da su sun haɗa da:
Gilashin kwalban shuɗi na gargajiya da ake amfani da shi a cikin fitilun halogen oxide (Fe2O3) yana da launin baƙin ƙarfe.
Cobalt oxide (CoO) - ana amfani dashi don yin gilashin shuɗi da kore.
Chromium oxide (Cr2O3) - ana amfani dashi a cikin samar da gilashin kore na jadeite.
Cadmium oxide (CdO) da manganese oxide (MnO2) - ana iya amfani da su don yin gilashin shunayya.
Copper (II) oxide (CuO) - ana amfani dashi don yin launin ruwan kasa da gilashin ruwan ja.
2. Rini da karfe ions
Rini na iya gabatar da ions ƙarfe a saman gilashin, wanda zai iya maye gurbin sauran ions a cikin lattice kuma yana taka rawa wajen ɗaukar haske na gilashin tabo. Rini yana nufin ƙari na ƙarfe oxides ko silicates masu kama da kaddarorin amma ba a narkar da su gaba ɗaya cikin gilashin turbid, waɗanda ake narkar da su ta hanyar dumama. Saboda tasirin bambancin zafin jiki, suna samar da Solid bayani tare da ƙananan solubility a cikin gilashin; A madadin, ana iya ƙara oxides na ƙarfe ko oxide precursors kai tsaye zuwa gilashin ƙarfi kuma a juye shi a yanayin zafi mai zafi don samar da gilashin launi. Ƙarfe ions da za a yi amfani da su sun haɗa da:
Iron oxide (Fe2O3) - ana iya amfani dashi don kera launin ruwan kasa, launin ruwan kasa, da gilashin baki.
Manganese oxide ko manganese (IV) oxide (MnO2) - ana iya amfani dashi don kera gilashin shunayya ko orange.
Cobalt oxide (CoO) - ana amfani dashi don yin gilashin shuɗi da kore.
Copper (II) oxide (CuO) - ana iya amfani dashi don yin shuɗi da kore.
Chromium oxide (Cr2O3) - ana amfani dashi a cikin samar da gilashin kore na jadeite.
3. Rini da Organic imines
Fasahar rini na gilashin gargajiya na buƙatar kiyaye takamaiman zafin jiki da jira na dogon lokaci, yayin amfani da hanyar rini na imine na halitta yana da sauri, yana buƙatar ɗan gajeren lokaci, kuma yana adana ƙarin albarkatun makamashi. A wannan hanya, ana amfani da nitroimines a matsayin masu launi, waɗanda za su iya amsawa tare da gilashin gilashi don samar da kwayoyin rini waɗanda ke ɗaukar tsayin tsayi na musamman, don haka canza launin gilashin. Ingancin sa ya fi sauran hanyoyin rini da yawa.
4. Yin amfani da hanyar launi na electrolytic
Launi na Electrolytic shine tsarin amfani da ingantaccen ingancin gilashi don canza launin gilashin bayyananne ta hanyar magance ions na atom daban-daban. A cikin tsarin canza launin electrolytic na al'ada na fina-finai na bakin ciki, ana ba da kayan zuwa cations a cikin gilashin don canza girman atomic, siffar da lambar daidaitawa, don haka samar da tasirin gani da ke hade da launi. Amfanin wannan hanya shine cewa zai iya samar da fim mai kama da gaskiya a kan gilashin gilashi, yana ba da damar ƙarin tabo iri ɗaya idan aka kwatanta da sauran hanyoyin.
A taƙaice, hanyoyin da ke sama su ne hanyoyin da za a iya amfani da su yayin kera kwalaben gilashi masu launi daban-daban. Tabbas, a cikin ayyukan da ake amfani da su, wasu lokuta ana amfani da hanyoyin haɗaka don kammala sarrafa launi. Sabili da haka, ana buƙatar ƙwararrun ma'aikatan fasaha don gudanar da ayyukan masana'antu da canza launi don tabbatar da ingancin samfurin.
