Umehluko Phakathi Kwekhabhoni Emhlophe Emnyama Ne-Silicon Dioxide
I-Silicon Dioxide (SiO2) yigama elijwayelekile lama-silicon oxides kumakhemikhali, atholakala kabanzi emvelweni (isb., i-quartz, isihlabathi, ikristalu) futhi angalungiswa futhi ngokwenziwe. Kuye ngesakhiwo kanye nokwakheka, i-silicon dioxide ingahlukaniswa ngezinhlobo zamakristalu (isb., i-quartz) kanye nefomu elingaguquki...Funda kabanzi -
Ukuhlaziywa Kwemakethe Ye-Silica Enezimvula
I-silica evundile, eyaziwa ngokuthi i-white carbon black, i-hydrated silica, noma i-silica elula, ayincibiliki emanzini kanye nama-asidi amaningi. Imunca umswakama emoyeni ukuze yakhe izinhlayiya ezincane ezihlanganisiwe futhi incibilike ku-caustic soda kanye ne-hydrofluoric acid. Ihlala iqinile ngokumelene namanye amakhemikhali, ukumelana...Funda kabanzi -
Isingeniso ku-Carbon Black
I-carbon black, eyaziwa njengommeleli we-carbon engaguquki, iyimpuphu emnyama elula, ethambile enendawo enkulu. Ikhiqizwa ngokuyinhloko ngokusha okungaphelele noma ukubola kokushisa kwezinto eziqukethe i-carbon (njengamalahle, igesi yemvelo, uwoyela osindayo, njll.) ngaphansi kwezimo ze ...Funda kabanzi -
Indima Ebalulekile Yekhabhoni Emnyama Emathayini
I-carbon black ingenye yezinto ezibalulekile ekukhiqizweni kwamathayi, ikakhulukazi esebenza njenge-ejenti yokuqinisa nokugcwalisa. Ithuthukisa kakhulu ukusebenza kwamathayi, okuhlanganisa amandla, ukumelana nokuguguleka, ukumelana nokuguga, kanye nokumelana nokukhathala. Iyini i-Carbon Black? I-carbon black iyi-carbon-...Funda kabanzi -
Kungenzeka ukufaka i-calcium chloride esikhundleni se-barium chloride ekuhlaziyweni kokugeza.
1. Ukunqunywa kwe-Sodium Hydroxide Esikhathini sezinyanga ezimbili, ama-reagent amabili ahlolwe ngesikhathi esifanayo ngenkathi kuhlaziywa isampula yekhasimende. Imiphumela yokuhlaziywa kokuqukethwe okuphansi kwe-Sodium Hydroxide yayifana ngokuyisisekelo, kanti ukuphambuka kokuqukethwe okuphezulu kwe-sodium hydroxide kwaku...Funda kabanzi
