Cov neeg siv khoom feem ntau muaj cov lus nug zoo li no: cov khoom siv tooj liab tube yog cim nrog "mos xeev", "hard state" thiab "semi-hard state". Puas muaj qhov sib txawv thaum siv nws?
Lub xeev lub raj tooj liab txhais li cas? Dab tsi yog qhov txawv ntawm lub xeev sib txawv ntawm cov raj tooj liab? Hnub no peb yuav qhia txog qhov teeb meem no kom ntxaws.
Dab tsi yog "nyuaj" tooj liab raj?
Lub zog tensile ntawm cov tawv tooj liab yog nruab nrab ntawm 320Mpa thiab 460Mpa, qhov elongation tsawg dua 5%, tus nqi hardness siab, Vickers hardness HV5 yog siab dua 100, muaj kev ntxhov siab sab hauv, muaj zog elasticity, thiab nws tsis haum rau loj. khoov. Cov raj tawv tooj liab feem ntau yog tsim los ntawm cov raj ncaj.
Qhov "mos" tooj liab raj yog dab tsi?
Piv nrog rau cov hlau tawv tawv, cov txheej txheem ua cov hlau mos tooj liab ntxiv cov txheej txheem annealing. Los ntawm annealing, tooj liab tube nplej yog ntxiv refined thiab cov kev ntxhov siab sab hauv raug tshem tawm. Lub zog tensile ntawm mos tooj liab raj yog nruab nrab ntawm 235Mpa thiab 255Mpa, thiab elongation yog li ntawm 50%. Cov tub ntxhais tooj liab mos muaj zog yooj, tsis tshua muaj hardness, thiab muaj zog yas, uas yog tsim rau reprocessing hauj lwm xws li khoov.
Lub hardness ntawm semi-rigid tooj liab raj yog nruab nrab ntawm cov tawv thiab mos.
Qhov sib txawv ntawm daim ntawv thov
Kev ntim khoom sib txawv
Cov raj tawv tooj liab feem ntau yog ntim rau hauv daim ntawv ntawm cov raj ncaj; thaum mos tooj liab raj yog ntim rau hauv ntau hom, nrog rau cov raj ncaj thiab coils. Hongtai mos tooj liab raj muaj ntau hom ntawv ntim, nrog rau cov raj ncaj, yoov tshaj cum, coils loj, thiab cov coils me, uas tuaj yeem hloov kho tau los ntawm cov neeg siv khoom raws li kev xav tau sib txawv.
Kev siv sib txawv
Qhov sib txawv ntawm lub xeev mos thiab tawv tsis tsuas yog ua rau daim ntawv thov kev taw qhia ntawm cov raj tooj liab sib txawv, tab sis kuj muaj kev cuam tshuam zoo rau kev tsim kho.
Mos tooj liab tubes muaj tsawg hardness, zoo tensile zog, thiab muaj zog txiav processability. Lawv tau siv ntau dua nyob rau hauv qhov chaw uas yuav tsum tau khoov, xws li cua txias, tub yees, thiab cov kav dej siv roj, uas yooj yim rau kev nthuav dav, flaring, thiab khoov cov haujlwm. Tsis tas li ntawd, txij li tag nrho cov coil ntev ntev dua, thaum cov yeeb nkab txuas cov ntsiab lus nyob deb sib nrug, lub raj tooj liab tuaj yeem txiav dawb raws li kev xav tau, yog li zam qhov tshwm sim ntawm cov xau thaum vuam cua txias tooj liab raj.
Txawm li cas los xij, cov raj tawv tooj liab tsis haum rau kev khoov vim lawv cov kev txwv. Lawv tsim nyog rau qhov chaw uas qhov kev sib txuas nrug ntev thiab khoov tsis tas yuav tsum tau.
