Nichrome hlau, npib tsib xee-chromium alloy (feem ntau 60-80% npib tsib xee, 10-30% chromium), yog cov khoom siv ua haujlwm ua kev zoo siab rau nws qhov tshwj xeeb sib xyaw ntawm qhov kub thiab txias, muaj zog tiv taus, thiab corrosion kuj. Cov yam ntxwv no ua rau nws tseem tsis tau muaj nyob hauv ntau qhov kev lag luam - los ntawm cov khoom siv hauv tsev niaj hnub mus rau qhov kev xav tau kev lag luam siab - thiab peb cov khoom siv nichrome hlau yog tsim los ua kom pom kev ua tau zoo hauv txhua qhov kev siv.
1. Cov Cuab Yeej Cuab Yeej: Cov Ntsiab Lus Thov
Kev siv ntau tshaj plaws ntawm nichrome hlau yog nyob rau hauv kev tsim cov khoom cua sov, ua tsaug rau nws lub peev xwm los hloov hluav taws xob hluav taws xob rau hauv cov cua sov kom zoo thiab ntseeg tau. Hauv cov khoom siv hauv tsev, nws ua rau cov cua sov coils hauv toasters, plaub hau tshuab ziab khaub ncaws, qhov cub hluav taws xob, thiab qhov chaw tso cua sov. Tsis zoo li lwm cov hlau uas muag los yog oxidize ntawm qhov kub thiab txias, peb cov nichrome hlau tswj kev ruaj ntseg txawm tias thaum cua sov mus rau 1,200 ° C, ua kom cov khoom siv khiav tsis tu ncua rau xyoo. Piv txwv li, cov cua sov coils hauv peb cov nichrome hlau yog tsim los nrog cov kev tiv thaiv zoo (feem ntau yog 1.0-1.5 Ω·mm² / m) kom xa cov cua sov tsis sib xws - tsis muaj qhov kub, tsuas yog qhov sov sov uas ua rau lub neej ntev.
Hauv kev lag luam chaw, nichrome hlau yog lub caj qaum ntawm cov cua kub cua sov. Nws yog siv nyob rau hauv industrial furnaces rau hlau annealing, yas molding tshuab, thiab kub kho qhov cub, qhov twg nws endures ntev raug rau huab cua sov yam tsis muaj degradation. Peb qhov hnyav-gauge nichrome hlau (0.5-5mm txoj kab uas hla) yog tsim los rau cov dej num no, nrog kev txhim kho oxidation tsis kam tiv thaiv kev ua haujlwm tsis tu ncua hauv kev lag luam hnyav.
2. Cov khoom siv kuaj thiab tshawb fawb
Nichrome hlau yog ib qho tseem ceeb nyob rau hauv lub chaw soj nstuam, qhov twg precision cua sov yog qhov tseem ceeb. Nws yog siv nyob rau hauv Bunsen burners (raws li lub cua sov lub caij rau hluav taws xob variants), cua sov mantles rau lub hwj chim cua sov, thiab kub tswj chamber. Peb cov nplua-gauge nichrome hlau (0.1-0.3mm txoj kab uas hla) ua tau zoo ntawm no - nws cov ductility siab tso cai rau nws los ua ib qho me me, intricate coils, thaum nws ruaj khov tiv thaiv kom paub meej qhov kub thiab txias, yuav tsum muaj kev sim siab.
3. Kev Tiv Thaiv Cheeb Tsam & Kev Siv Tshwj Xeeb
Tshaj cua sov,nichrome hlau's ib txwm hluav taws xob resistivity ua rau nws zoo tagnrho rau cov ntsiab lus resistor hauv electronics, xws li (taw resistors) thiab potentiometers. Nws kuj pom siv nyob rau hauv tshwj xeeb teb: nyob rau hauv 3D printing, nws powers rhuab txaj rau filament adhesion; nyob rau hauv aerospace, nws yog siv rau me me cua sov ntsiab nyob rau hauv avionics; thiab hauv cov haujlwm ua haujlwm (xws li cov qauv tsheb ciav hlau lossis DIY cua sov), nws yooj yim siv thiab pheej yig ua rau nws nyiam.
Peb cov khoom siv nichrome hlau muaj nyob rau hauv ntau qib (xws li NiCr 80/20 thiab NiCr 60/15) thiab cov lus qhia tshwj xeeb, los ntawm cov xov hlau zoo heev rau kev siv me me rau cov xov hlau tuab rau kev siv hnyav. Txhua yob tau txais kev soj ntsuam nruj nruj-xws li kev txheeb xyuas cov khoom sib xyaw thiab cov tshuaj tiv thaiv-kom paub meej tias nws ua tau raws li cov qauv kev lag luam. Txawm hais tias koj xav tau cov khoom siv hluav taws xob txhim khu kev qha rau cov khoom siv hauv tsev lossis cov kev daws teeb meem ruaj khov rau cov khoom siv hluav taws xob, peb cov nichrome xaim muab cov kev ua tau zoo, kev ua neej ntev, thiab kev sib xws uas koj xav tau.
