Graphite tuag technology rau Graphite Tuag
Graphite Die deg kho tshuab, los ntawm cov txheej deg, qhov kev hloov kho lossis kev siv hluav taws xob los hloov cov Graphite Die deg morphology, tshuaj lom neeg muaj pes tsawg leeg, qauv thiab kev nyuab siab lub xeev, thiaj li yuav tau txais qhov tsim nyog ntawm kev ua haujlwm hauv qhov system. Tam sim no nyob rau hauv Graphite tuag tsim ntau daim ntaub ntawv mas yog nitriding, carburising thiab hardening zaj duab xis deposit.
Raws li cov cuab yeej nitriding tsim tau ib qho kev ua tau zoo ntawm nto, thiab cov txheej txheem nitriding thiab Graphite tuag quenching txheej txheem muaj kev sib koom tes zoo, hos cov nitriding kub yog tsawg, nitriding tsis txias, Graphite tuag deformation tsawg heev, ces Graphite Tuag deg yog siv cov npe ntawm nitriding ua ntej, tab sis kuj tseem siv tau ntau tshaj plaws.
Pwm graphite carburizing yog los txhim kho lub zog ntawm qhov Graphite Die, uas yog, Graphite Die ua hauj lwm nto nrog lub zog thiab hnav tsis kam. Raws li cov kev kho mob tam sim no, cov nqi ntawm cov khoom cua khov ua pov tseg (khoom siv khoom) siab, tseem tsuas yog nyob hauv qee qhov kev txiav txim siab, lub neej ntev Daim Ntawv Graphite Die, yog siv cov lag luam ntawm cov chaw kho qhov chaw sov, cov nqi ntawm txheej hardened film yuav zoo heev txo, ntau Graphite tuag yog koj siv cov tshuab no, koj yuav txhim kho qib tag nrho ntawm Tuam Tshoj Graphite tuag raug.
Nrog rau kev txhim kho ntawm kev siv tshuab thiab txiav twj kev ua tau zoo, kev loj hlob ntawm kev siv tshuab ua ntej siv Graphite Die tau ceev nrooj. Los ntawm cov 1980s, qhov kev faib ua feem ntawm cov txheej txheem muaj zog hauv cov tuaj pwm muaj 30%.
Cov ntaub ntawv muaj txheej txheem yog cov xim tsis muaj hlau, copper, aluminium, hlau alloy, thiab lwm yam, tsis muaj teeb meem zoo li cas cov khoom pwm tsis tuaj yeem muaj ob qhov siab, muaj av qeeg, Yog li, cov neeg txuas mus nrhiav cov ntaub ntawv tshiab ua pwm, thiab thaum kawg pom cov graphite, Graphite tuag nrog txhua qhov zoo saum toj no, zoo li cov khoom zoo tshaj plaws rau cov khoom pwm.
Hnub no, kev lag luam ntau thiab ntau dua Graphite Tuag, ntau hom txawb iav Rewriting Graphite Tuag, hluav taws xob sintered Graphite Tuag, exothermic welding Graphite Tuag los hloov cov pwm no, ua cov ntawv thov pwm feem ntau.
Graphite khoom muaj cov nram qab no zoo li nram qab no:
(1) kev kub siab: graphite melting point ntawm 3850 ± 50 ℃, boiling point ntawm 4250 ℃, txawm tias qhov kub kub ulc kub, qhov poob phaus me heev, thermal expansion coefficient tseem heev me me. Graphite zog yog kho kom zoo dua nrog kev ua kom sov, ua ob lub zog ntawm graphite ntawm 2000 ° C.
(2) cov khoom siv, thermal conductivity: graphite conductivity tshaj lub qho non-metallic mine ntawm ib puas npaug dua. Thermal conductivity dua hlau, hlau, txhuas thiab lwm yam khoom siv hlau. Thermal conductivity decreases nrog nce kub, txawm tias thaum kub heev, graphite rau hauv kev ntsuas cua sov.
(3) Lubrication: graphite lubrication kev ua haujlwm nyob ntawm qhov loj ntawm graphite dos, qhov loj dua qhov ntsuas, me dua qhov coefficient ntawm kev sib txhuam, qhov zoo dua qhov kev ua lubrication.
(4) kev ruaj ntseg tshuaj: graphite ntawm chav tsev kub muaj zoo tshuaj ruaj khov, kua qaub, alkali thiab ua hauj lwm rau cov organic solvents corrosion.
(5) Cog nplej: kev ua lub teeb toughness yog qhov zoo, tuaj yeem raug muab khov rau hauv nyias lub ncuav.
(6) thermal poob hauj lwm: tha teeb ntawm chav tsev kub thaum siv los ua rau cov kev hloov hauv kub tsis muaj kev puas tsuaj, qhov kev hloov ntawm qhov kub, lub ntim ntawm lub graphite hloov me ntsis, tsis muaj kab nrib pleb.
Qhov tshwj xeeb zoo ntawm graphite cov ntaub ntawv ua nws zoo tshaj plaws cov ntaub ntawv rau kev tsim moulds, dav siv nyob rau hauv lub lag luam electronics, photovoltaic kev lag luam, iav kev lag luam, nonferrous hlau kev lag luam thiab lwm yam kev ua. Feem ntau siv Graphite Tuag nrog sintered Graphite Tuag, mobile iav Rewriting Graphite Tuag, exothermic welding Graphite Tuag.
