Izinto eziPhakamileyo zokuBanga izicelo

ISapphire luhlobo lwecrystalline ye-aluminium oxide (Al₂O₃) kwaye ibekwe kwindawo engaphantsi kwedayimane ngokobunzima, inqaku le-9 kwisikali se-Mohs. Obu bunzima bungaqhelekanga benza iityhubhu zesafire zimelane kakhulu nokukrweleka, ukukrazuka, kunye neempembelelo zoomatshini, naphantsi kokusetyenziswa rhoqo okanye ngamandla.

Ngaphandle kwamandla omatshini, iityhubhu zesafire zixabiswa kakhulu ngenxa yokumelana nemichiza. Zihlala zizinzile kwaye zingasebenzi phambi kobuninzi be-acids, i-solvents, kunye neegesi ezisebenzayo, kuquka i-hydrogen fluoride, i-chlorine, kunye ne-sulfur compounds. Oku kubavumela ukuba basebenze ngokufanelekileyo kwiinkqubo ezibandakanya iikhemikhali ezinobundlobongela okanye iplasma.

Ukongeza, ukusebenza kwe-thermal yesafire kuyamangalisa. Imelana nokuvezwa ixesha elide kumaqondo obushushu ukuya kuma-2000°C ngelixa igcina imfezeko yesakhiwo sayo.

Enye inzuzo ebalulekileyo yi-optical transparency kwi-ultraviolet, ebonakalayo, kunye ne-infrared wavelengths-ukusuka malunga ne-0.3 μm ukuya kwi-5 μm. Oku kwenza iityhubhu zesafire zilungele ukubonwa kwe-optical sensing okanye iinkqubo ezidityanisiweyo zokujonga i-thermal-optical monitoring.

Thermocouples kunye nesidingo soKhuselo

I-Thermocouples zizinto ezibalulekileyo kuluhlu olubanzi lweenkqubo, ukusuka kwiziko zentsimbi kunye neenjini ze-injini ye-injini ye-injini ye-semiconductor kunye nezixhobo zenkqubo yekhemikhali. Ezi zixhobo zivelisa amandla ombane ngokusekelwe kumahluko obushushu phakathi kweentsimbi ezimbini ezidityanisiweyo ezidityaniswe kwelinye icala. Ngelixa ii-thermocouples zinezinto ezininzi kwaye zomelele, ukuvezwa kwazo ngokuthe ngqo kubushushu, i-ejenti ezonakalisayo, kunye nomothuko womatshini kunokunciphisa kakhulu ubomi babo benkonzo okanye kuthobe ukuchaneka kofundo lobushushu.

Kulapho iityhubhu zesafire zingena khona njengeeshethi zokukhusela. Ngokufaka i-thermocouple ngaphakathi kwityhubhu yesafire, inzwa yodwa kwindawo enzima ngelixa ivumela ukuhanjiswa kobushushu ngokufanelekileyo. Isiphumo sihlala ixesha elide, inzwa ethembekileyo ngakumbi egcina ukuchaneka okungaguqukiyo nasemva kokuvezwa ixesha elide kwiimeko zokusebenza ezinobundlobongela.

I-Sapphire's conductivity ye-thermal conductivity ivumela ubushushu ukuba bufikelele kwi-thermocouple ngokukhawuleza kwaye ngokulinganayo, ukunciphisa i-lag yeqondo lokushisa kunye nokuphucula ixesha lokuphendula. Ngaphezu koko, ukuchasana kwayo nokuhlaselwa kweekhemikhali kuqinisekisa ukuba i-sensor ayinyanzelwanga yi-residues, i-corrosion, okanye i-buildup material-imiba ehlala ibetha isinyithi okanye imikhono yokukhusela i-ceramic.

Sebenzisa Amatyala kuHlolo loMongo
