Kuyimfuneko ukwamkela iindlela ezahlukeneyo zokwenza ukuba iglasi kunye nesigcwalisi seglasi sitywinwe ukwenza iimveliso ezinemilo enzima kwaye zifezekise iimfuno ezikhethekileyo, ezinje...Funda ngokugqithisileyo -
Imbali yoPhuhliso lweLizwe leglasi
Ngo-1994, iUnited Kingdom yaqala ukusebenzisa iplasma kuvavanyo lokunyibilika kweglasi. Ngo-2003, iSebe lase-United States lamandla kunye nombutho woshishino lweglasi lenze uvavanyo loxinaniso lwe-pool encinci ye-high-intensity plasma melting E glass and glass fibers, igcina amandla angaphezu kwama-40%. IJapan n...Funda ngokugqithisileyo -
Uphuhliso Trend of Glass
Ngokwenqanaba lophuhliso lwembali, iglasi inokwahlulwa ibe yiglasi yakudala, iglasi yemveli, iglasi entsha kunye neglasi yexesha elizayo. (1) Kwimbali yeglasi yamandulo, amaxesha amandulo ayedla ngokubhekisela kwixesha lobukhoboka. Kwimbali yaseTshayina, amaxesha amandulo aquka uluntu lwamaShiji. Pha...Funda ngokugqithisileyo -
Iindlela zokucoca zeemveliso zeglasi
Kukho iindlela ezininzi eziqhelekileyo zokucoca iglasi, ezinokuthi zishwankathelwe njengokucoca i-solvent, ukufudumeza kunye nokucoca i-radiation, ukucocwa kwe-ultrasonic, ukucoca ukukhutshwa, njl. Ukucoca i-solvent yindlela eqhelekileyo, esebenzisa amanzi...Funda ngokugqithisileyo -
I-14.0-I-Sodium calcium ibhotile yokwakhiwa kweglasi
Ngokusekelwe kwinkqubo ye-SiO 2-CAO -Na2O ternary, izithako zeglasi ze-sodium kunye ne-calcium zongezwa kunye ne-Al2O 3 kunye ne-MgO. Umahluko kukuba umxholo we-Al2O 3 kunye ne-CaO kwiglasi yebhotile iphezulu, ngelixa umxholo we-MgO uphantsi. Nokuba luhlobo luni lwesixhobo sokubumba, yiba...Funda ngokugqithisileyo -
I-13.0-Ibhotile ye-Sodium ye-calcium kunye ne-jar glass composition
I-Al2O 3 kunye ne-MgO zongezwa ngesiseko se-SiO 2-cao-na2o inkqubo ye-ternary, eyahlukileyo kwiglasi yeplate yokuba umxholo we-Al2O 3 uphezulu kwaye umxholo we-CaO uphezulu, ngelixa umxholo we-MgO uphantsi. Nokuba luhlobo luni lwezixhobo zokubumba, nokuba ziibhotile zebhiya, utywala bo...Funda ngokugqithisileyo -
12.0-Ukwakheka kunye nezinto ezikrwada zebhotile kunye neglasi yeglasi
Ukubunjwa kweglasi yenye yezinto eziphambili ezimisela ubume beglasi, ke ngoko, ukubunjwa kweekhemikhali zebhotile yeglasi kwaye kufuneka kuqala ihlangabezane neemfuno zomzimba kunye neekhemikhali zebhotile yeglasi kwaye, kwangaxeshanye, ukudibanisa ukunyibilika, ukubumba. kwaye iprosesa...Funda ngokugqithisileyo -
11.0-Iimpawu ze-Optical zeglasi yeglasi
Ibhotile kunye neglasi inokunqumla ngokufanelekileyo imitha ye-ultraviolet, ithintele ukuwohloka kwezinto eziqulethweyo. Umzekelo, ibhiya ibonakaliswe kukukhanya okuluhlaza okwesibhakabhaka okanye okuluhlaza kunye nobude obungaphantsi kwe-550nm kwaye iya kuvelisa ivumba, elaziwa ngokuba yincasa yelanga. Iwayini, isosi kunye nokunye ukutya nazo ziya kuba af...Funda ngokugqithisileyo -
Izinto ezichaphazela ukuzinza kweekhemikhali zeglasi
Ukumelana namanzi kunye nokuchasana kwe-asidi yeglasi ye-silicate inqunywe ngokukodwa ngumxholo we-silica kunye ne-alkali metal oxides. Ukuphakama komxholo we-silica, iqondo elikhulu lokudibanisa phakathi kwe-silica tetrahedron kunye nokuphakama kozinzo lweekhemikhali zeglasi. kunye ne...Funda ngokugqithisileyo -
I-10.0-Iimpawu zeMechanical yeebhotile zeglasi kunye neengqayi
Ibhotile kunye neglasi kufuneka ibe namandla athile omatshini ngenxa yokusetyenziswa kweemeko ezahlukeneyo, inokuba phantsi koxinzelelo olwahlukileyo. Ngokubanzi inokwahlulwa ibe ngamandla oxinzelelo lwangaphakathi, ukumelana nobushushu kwimpembelelo, amandla efuthe loomatshini, amandla esikhongozeli angaphezulu...Funda ngokugqithisileyo
