Ngaphambi kokuqonda indlela yokuchonga kunye nokukhetha izinto zeCuNi44, kufuneka siqonde ukuba yintoni i-copper-nickel 44 (CuNi44). I-nickel 44 yobhedu (CuNi44) yimathiriyeli ye-copper-nickel alloy. Njengoko igama layo libonisa, ubhedu ngenye yezinto eziphambili ze-alloy. I-Nickel nayo enye yezinto eziphambili, ezinomxholo we-43.0% - 45.0%. Ukongezwa kwe-nickel kunokuphucula amandla, ukuxhathisa kwe-corrosion, ukuchasana kunye neempawu ze-thermoelectric ze-alloy. Ukongezelela, ibandakanya kodwa ingaphelelanga kwi-0.5% - 2.0% manganese. Ubukho be-manganese bunceda ekuphuculeni ukuxhathisa kwe-corrosion, ukuzinza kwe-thermal kunye nokomelela kwe-alloy, kodwa i-manganese egqithisileyo inokubangela ukubola.
I-Copper-nickel 44 ine-coefficient yokushisa ephantsi yokumelana, kwaye ukuchasana kwayo kuzinzile xa iqondo lokushisa litshintsha, okwenza kube luncedo kwizicelo apho ukuzinza kokumelana kuyadingeka. Xa iphantsi koxinzelelo kunye nokuguqulwa, isizathu sokuba i-nickel-nickel 44 ikwazi ukugcina ukusebenza okuzinzileyo kukuba i-coefficient yayo ye-sensitivity ye-strain ayitshintshi ngexesha loxinzelelo lweplastiki kwaye i-hysteresis yomatshini incinci. Ukongeza, i-CuNi44 inamandla amakhulu e-thermoelectric kubhedu, inokusebenza kakuhle kwe-welding, kwaye ilungele ukusetyenzwa kunye nokudibanisa.
Ngenxa yezinto ezintle zombane kunye nezomatshini, i-CuNi44 isoloko isetyenziselwa ukuvelisa izinto ezahlukeneyo ze-elektroniki ezifana ne-resistors, i-potentiometers, i-thermocouples, njl., umzekelo, njengenxalenye ephambili kwizixhobo zombane ezichanekileyo. Kwintsimi yemizi-mveliso, ingasetyenziselwa ukwenza iibhokisi zokumelana nomthwalo ophezulu, iirheostats kunye nezinye izixhobo. Ngenxa yokunganyangeki kwayo kakuhle, ikwalungele iindawo ezisingqongileyo ezineemfuno zokuxhathisa umhlwa ezifana noomatshini beekhemikhali kunye namalungu enqanawa.
Xa sithenga iimveliso, sichonga njani izixhobo zeCuNi44? Nazi iindlela ezintathu zokuchonga zereferensi yakho.
Okokuqala, eyona ndlela intuitive kukusebenzisa izixhobo zokuhlalutya iikhemikhali zobuchwephesha.Njengee-spectrometers, njl., Ukuvavanya ukubunjwa kwezinto. Qinisekisa ukuba umxholo wobhedu yintsalela, umxholo we-nickel ngu-43.0% - 45.0%, umxholo wesinyithi ngu-≤0.5%, umxholo we-manganese ngu-0.5% - 2.0%, kunye nezinye izinto zingaphakathi koluhlu oluchaziweyo. Xa abathengi bethu bethenga iimveliso ze-tankii, sinokubanika isatifikethi somgangatho okanye ingxelo yovavanyo lwezinto.
Okwesibini, chonga ngokulula kwaye ukhuse ngeempawu zembonakalo yemveliso.Isixhobo seCuNi44 sihlala sibonakalisa ukukhazimla kwesinyithi, kwaye umbala unokuba phakathi kobhedu kunye nenickel. Qaphela ukuba umphezulu wezinto eziphathekayo ugudile, ngaphandle kweziphene ezicacileyo, i-oxidation okanye i-rust.
Indlela yokugqibela kukuvavanya iimpawu ezibonakalayo zemveliso - ukulinganisa ubuninzi kunye nobunzima bezinto eziphathekayo.CuNi44inoluhlu oluthile loxinaniso, olunokuvavanywa ngezixhobo zokulinganisa ubuninzi bobuchwephesha kwaye luthelekiswe nexabiso eliqhelekileyo. Inokulinganiswa kunye nomvavanyi wobulukhuni ukuqonda ukuba ubulukhuni bayo budibana noluhlu oluqhelekileyo lwe-nickel ye-copper-nickel 44.
Imarike inkulu kakhulu, indlela yokukhetha umthengisi ohlangabezana neemfuno zethu zokuthenga?
Ngexesha lophando, abathengi kufuneka bacacise iimfuno zokusetyenziswa.Umzekelo: misela usetyenziso oluthile lwemathiriyeli. Ukuba isetyenziselwa ukuveliswa kwecandelo lombane, iimpawu zayo zombane, ezifana ne-coefficient ephantsi yokumelana nokushisa kunye nokusebenza kakuhle kwe-welding, kufuneka kuthathelwe ingqalelo; ukuba isetyenziselwa oomatshini beekhemikhali okanye iinxalenye zeenqanawa, ukuxhathisa kwayo ukubola kubaluleke ngakumbi. Ukudibanisa nokusetyenziswa kwe-terminal, ukushisa, uxinzelelo, ukubola kunye nezinye izinto zendawo yokusetyenziswa zithathelwa ingqalelo ukuze kuqinisekiswe ukuba i-CuNi44 esiyithengayo inokusebenza ngokuqhelekileyo phantsi kwezi meko.
Ngaphezu koko, ngexesha lophando, unokuvavanya umthengisi ngokujonga isatifikethi sesiqinisekiso somthengisi, ukuvavanywa komthengi, isidima soshishino, njl.
Ukongeza kula manqaku mabini angentla, ulawulo lweendleko nalo lubalulekile.Kufuneka sithelekise amaxabiso ababoneleli abahlukeneyo. Ewe, asinakusebenzisa nje ixabiso njengenye inqobo yokukhetha. Kubalulekile ngokulinganayo ukuqwalasela izinto ezifana nomgangatho wezinto eziphathekayo, ukusebenza kunye nenkonzo emva kokuthengisa. Ubomi benkonzo yezinto eziphathekayo buhambelana ngqo neendleko zokugcina. Izinto ezikumgangatho ophezulu weCuNi44 zinokuba neendleko eziphezulu zokuqala, kodwa zinokugcina iindleko zokugcinwa kunye nokutshintshwa kokusetyenziswa kwexesha elide.
Ekugqibeleni, kubalulekile ukukhankanya ukuba ngaphambi kokuthenga iimveliso kwizinga elikhulu, unokucela umthengisi ngeesampuli zokuvavanya. Vavanya ukuba ngaba ukusebenza kwemathiriyeli kuyahlangabezana neemfuno, ezinje ngeempawu zombane, ukuxhathisa ukubola, iipropathi zemishini, njl.njl. Ngokusekwe kwiziphumo zovavanyo, jonga ukuba ukhethaubhedu-nickel 44impahla yomthengisi.
