Umahluko Phakathi kweCarbon Emhlophe Emnyama kunye neSilicon Dioxide
I-Silicon Dioxide (SiO2) ligama eliqhelekileyo le-silicon oxides kwikhemistri, efumaneka kakhulu kwindalo (umz., i-quartz, isanti, ikristale) kwaye ingalungiswa ngokwenziweyo. Ngokuxhomekeke kwisakhiwo kunye nemo, i-silicon dioxide inokwahlulwahlulwa ibe ziifom zekristale (umz., i-quartz) kunye nefom ye-amorphous...Funda ngokugqithisileyo -
Uhlalutyo lweMarike yeSilica eNciphisiweyo
I-silica evuthulukileyo, eyaziwa ngokuba yi-white carbon black, i-hydrated silica, okanye i-silica ekhaphukhaphu, ayinyibiliki emanzini nakwi-asidi ezininzi. Ifunxa umswakama emoyeni ukuze yenze amasuntswana amancinci adibeneyo kwaye inyibilike kwi-caustic soda kunye ne-hydrofluoric acid. Ihlala izinzile ngokuchasene nezinye iikhemikhali, ukumelana...Funda ngokugqithisileyo -
Intshayelelo kwiCarbon Black
I-carbon black, eyaziwa ngokuba ngummeli we-amorphous carbon, yi-powder emnyama ekhaphukhaphu nethambileyo enomhlaba omkhulu. Iveliswa ngokuyintloko ngokutsha okungaphelelanga okanye ukubola kobushushu kwezinto eziqulethe i-carbon (ezifana namalahle, igesi yendalo, ioyile enzima, njl.njl.) phantsi kweemeko ze ...Funda ngokugqithisileyo -
Indima Ebalulekileyo YeCarbon Black KwiiTayara
Umnyama wekhabhoni yenye yezinto ezibalulekileyo ekuvelisweni kwamatayara, ikakhulu isebenza njengesixhobo sokuqinisa nokugcwalisa. Iphucula kakhulu ukusebenza kwamatayara, kubandakanya amandla, ukumelana nokuguguleka, ukumelana nokwaluphala, kunye nokumelana nokudinwa. Yintoni iKhabhoni emnyama? Umnyama wekhabhoni yikhabhoni...Funda ngokugqithisileyo -
Kunokwenzeka ukutshintsha i-barium chloride nge-calcium chloride xa kuhlalutywa ukuhlamba.
1. Ukuqinisekiswa kweSodium Hydroxide Kwisithuba seenyanga ezimbini, ii-reagents ezimbini zavavanywa ngaxeshanye ngelixa kuhlalutywa isampuli yomthengi. Iziphumo zohlalutyo lomxholo ophantsi weSodium Hydroxide bezihambelana ngokusisiseko, ngelixa ukuphambuka komxholo ophezulu wesodium hydroxide beku...Funda ngokugqithisileyo
