Hlau sab hauv qauv
Vim tias cov hlau uas muaj cov khoom siv hluav taws xob tuaj yeem txav tau yooj yim, thaum kawg ntawm cov hlau nrog lub zog hluav taws xob, qhov zoo ntawm cov khoom sib xyaw ua ke yog qhov zoo, qhov tsis zoo ntawm cov khoom tawg yog qhov tsis zoo, vim hais tias zoo li cov nqi sib txawv, tsis zoo li cov nqi sib tw, yog lub zog rau kev taw qhia hluav taws xob. , li no yuav ua tau conductive, uas yog vim li cas cov hlau yuav conductive.
Cov hluav taws xob tam sim no yog cov kev taw qhia ntawm cov hluav taws xob, yog li lub peev xwm ntawm cov hlau ua hluav taws xob txhais tau hais tias muaj coob tus ntawm cov hluav taws xob txav mus los hauv cov hlau, uas yog qhov tseem ceeb ntawm kev ua haujlwm zoo.
Ua ntej, cia peb saib cov qauv sab hauv ntawm cov hlau. Qhov tseeb, tag nrho cov khoom hlau yog siv lead ua. Nyob rau hauv lub spatial qauv ntawm nws cov lattice, txhua lub node muaj tsis xwm yeem atoms los yog zoo ions, thiab electrons yog shuttling los ntawm lawv.
Thaum tsis muaj lwm yam kev ua, cov electrons nyob rau hauv ib tug hlau txav zoo li molecules nyob rau hauv ib tug random thiab random yam, yog li ntawd lub zog ntawm ntau electrons tshem tawm ib leeg, nrog ib tug nruab nrab tshaj tawm ntawm xoom nyob rau hauv ob txoj kev, yog li cov hlau tsis muaj. tam sim no.
Electrons nyob rau hauv ib tug hlau txav nyob rau hauv ib tug random txoj kev (uas yog ib tug yog vim li cas rau kev tiv thaiv), tab sis thaum muaj ib tug sab nraud lub hwj chim qhov chaw nrog ib tug muaj peev xwm sib txawv, cov electrons tsiv mus nyob rau hauv ib tug kev taw qhia kev taw qhia los ua hluav taws xob. Lub thermal txav ntawm cov khoom nce nrog qhov nce ntawm qhov kub thiab txias, thaum cov hluav taws xob conductivity yog tshwm sim los ntawm kev taw qhia ntawm electrons. Qhov nce ntawm qhov kub thiab txias ua rau kev txav mus los chaotic thiab cov hluav taws xob conductivity txo.
Ua rau crimping tsis kam
Lub crimp tsis kam ntawm tus neeg xyuas pib kev sib txuas, xws li kev sib txuas txias crimp, yog txuas nrog cov tub ntxhais xoob xoob xaim mus rau lub tes tsho hlau, tsim kev sib txuas tom qab cov cuab yeej sab nraud tau crimp deformed. Daim duab hauv qab no qhia tau hais tias kev sib cuag ntawm cov tub ntxhais xov hlau ua ntej txias nias yog xaim sib cuag. Lub zog hluav taws xob yuav tsum tau tawg los ntawm qhov nruab nrab ntawm qhov nruab nrab, tab sis kev sib cuag ntawm cov tub ntxhais xov hlau yog me me thiab kev tiv thaiv kev sib cuag loj.
Tom qab qhov zoo tshaj plaws crimping tiav lawm, kev tiv thaiv kev sib cuag yuav txo qis vim qhov kev nkag mus thiab kev sib tshuam ntawm qhov extrusion nto ntawm cov tub ntxhais hlau sab hauv thiab lub tes tsho hlau sab nraud, thiab qhov tsis kam ua me me ntawm no piv rau cov tub ntxhais hlau tsis kam. Kev tiv thaiv kev tiv thaiv kuj tuaj yeem raug xam ua ntej raws li cov qauv kev paub txog engineering.
High quality crimping, tub ntxhais hlau thiab sab nraud hlau casing deformation extrusion nto permeate sib soluble.
Qhov no kuj piav qhia txog qhov yuav tsum tau ua ntawm compression piv thiab rub tawm quab yuam kom lav crimping hauv cov qauv crimping cov qauv.
Cov nyhuv ntawm tawg strands
Yog li cas filament breakage cuam tshuam rau conduction? Muaj ntau cov hlua ntawm cores nyob rau hauv cov hlau. Vim muaj qhov muaj kev sib cuag ntawm cov tub ntxhais hlau, txhua tus tub ntxhais hlau ua tiav qhov kawg-rau-kawg conduction ntawm nws tus kheej, thiab sab hauv pub dawb yuav tsis txav mus rau hauv ntau cov tub ntxhais hlau ntawm qhov xav tau.
Yog hais tias lub strand yog tawg nyob rau hauv nruab nrab, ib feem ntawm tus nqi ntawm cov hlau core hlau txav mus rau ib puag ncig core xaim, tsim aggregation ntawm lub pob txha, ua kom muaj cua sov ntau, conductor kuj nce, kub nce.
Yog hais tias qhov kev sib txuas ntawm cov hlau thiab lub davhlau ya nyob twg tau tawg, nws muaj qhov cuam tshuam zoo ib yam li qhov nruab nrab tawg, thiab qhov kev sib txuas txias txias ntau dhau deformation kuj tseem yuav muaj cov tub ntxhais hlau tawg, thiab tom qab ntawd cuam tshuam rau tag nrho cov conduction.
