Borosilicate Glass yi kumile nyingiso eka ku tlakuka ka yona loku vuriwaka eka nghilazi ya ntolovelo eka ku paka switolwa na switirhisiwa swin’wana swotala. Kambe xana swa antswa hakunene?
Eka xitsalwana lexi, hi nghenelela eka swiphemu, swihlawulekisi, swipfuno eka nghilazi ya ntolovelo, na tinxaka to hambana ta nghilazi ya borosilicate ku nyika ku twisiseka eka mhaka leyi.
Xana nghilazi ya borosilicate i yini?
Nghilazi ya borosilicate yi endliwe kusuka eka 2 wa switirhisiwa leswikulu: silica na boron. Silica’s melting point yile henhla swinene (1730°C), ku endla leswaku nchumu lowu wu lulamisiwa eka mahiselo yale hansi xikan’we naku hlayisa matimba, swiphemu swin’wana leswi vuriwaka ti fluxes swa engeteriwa. Nakambe, ti stabilizers tin’wana (alkaline oxides, alumina, na alkaline oxides) ti cheriwa ku tiyisisa nghilazi, leswi nyikaka swivumbeko swa kahle swinene.
The Composition of Borosilicate Glass 70% to 80% silica (main component) 5% to 13% boron trioxide (main component) 4% to 8% alkaline oxides (stabilizers) from 2% to 7% alumina (stabilizers) from 0% to 5% of other alkaline oxides such as calcium oxide, magnesium oxide, etc. Borosilicate Swihlawulekisi swa miri wa nghilazi
Swipfuno swa nghilazi ya borosilicate ku lwisana na tikhemikhali ta kahle swinene: ku tiya ka tikhemikhali lokukulu swinene na ku tiya eka tindzhawu leti onhaka. Ku tiya ka mahiselo yale henhla: ku lwisana swinene na thermal shock na thermal gradients, na ku anama ka mahiselo yale hansi. Matimba ya kahle swinene ya michini: Highly wear- na scratch-resistant, na matimba yo tshembheka ya flexural xikan’we na vuswikoti byo tiyisela ndzhwalo wa michini lowu lavaka. Ku vonakala ka le henhla: Ku tiyisisa ku vonakala lokunene na ku hundziseriwa ka ku vonakala loku nga riki na ku soholotiwa eka spectral range yo anama swinene. Tinxaka ta Borosilicate Glass
Borosilicate Glass yifika hi tinxaka tohambana hambana kuya hi nhlayo ya boron oxide, leswi khumbaka swivumbeko swa yona. Tinxaka leti ti katsa:
nghilazi ya borosilicate yale hansi: Muxaka lowu wuna tiphesente tale hansi ta boron oxide, hi ntolovelo kusuka eka 5% kuya eka 10%. Yinyika ku lwisana na thermal shock yoringanela naswona yitala kutirhisiwa eka swilo swale kaya swofana na swibya swo sweka na swinwiwa. Nghilazi ya borosilicate yale xikarhi: Hi boron oxide content kusuka eka 10% kuya eka 13%, medium borosilicate glass yinyika enhanced thermal shock resistance loko yi pimanyisiwa na low borosilicate variant. Yi kuma switirhisiwa eka switirhisiwa swa laboratory na swivandla swa ti indasitiri laha ku lavekaka ku tiya ka le henhla. Glass ya Borosilicate yale henhla: Glass yale henhla ya borosilicate yina tiphesente tale henhla ta boron oxide, hi xitalo yi tlula 13%. Muxaka lowu wu tinyungubyisa hi ku lwisana ka xiyimo xa le henhla ka ku hisa ka ku hisa na ku tiya ka tikhemikhali, leswi endlaka leswaku wu faneleka eka switirhisiwa leswi lavaka swo fana na switirhisiwa swa nghilazi swa le laboratori na ti-optics ta matirhelo ya le henhla. Mahetelelo
Hiku gimeta, Borosilicate Glass yinyika swipfuno swotala eka nghilazi ya ntolovelo, kukatsa na thermal shock yale henhla xikan’we naku lwisana na ti khemikhali, xikan’we naku engetelela ku tiya. Hambi leswi nghilazi ya borosilicate yinga fika hi ntsengo wale henhla, matirhelo ya yona yo hlawuleka xikan’we na vutomi byo leha switala ku lulamisa vuvekisi, ngopfu ngopfu eka ku pakiwa ka switolwa.
