Graphite phaj yog cov khoom tseem ceeb uas tau siv dav hauv cov cua kub kub, cov khoom siv kho cua sov thiab ntau yam kev lag luam. Zoo thermal conductivity, kub tsis kam thiab siab zog ua graphite phaj yog zoo tagnrho fireproof khoom. Txawm li cas los xij, kev ua haujlwm ntawm graphite phaj yog cuam tshuam los ntawm nws cov txheej txheem kev npaj thiab cov khoom siv raw, yog li kev xaiv kom raug ntawm cov khoom siv graphite yog qhov tseem ceeb heev los xyuas kom meej qhov kev ua haujlwm zoo thiab kev pabcuam lub neej ntawm cov khoom siv.
Raw Materials rau Graphite Phaj
Cov khoom siv raw rau graphite boards feem ntau suav nrog ntuj flake graphite, dag graphite thiab sib xyaw graphite. Ntawm lawv, ntuj flake graphite muaj siab purity thiab kub tsis kam, tab sis muaj kev cuam tshuam rau impurities, dag graphite muaj thermal conductivity thiab corrosion kuj tab sis tus nqi siab, thiab sib xyaw graphite sib xyaw ua ke zoo ntawm ntuj flake graphite thiab graphite, thiab kuj muaj siab. tus yam ntxwv ntawm tus nqi.
Qhov thib ob, cov txheej txheem kev npaj ntawm graphite phaj
Cov txheej txheem kev npaj ntawm graphite phaj feem ntau suav nrog kev siv tshuaj, molding, sintering thiab txias. Ntawm lawv, koob tshuaj yog ib qho ntawm cov kev sib txuas tseem ceeb, uas cuam tshuam ncaj qha rau cov yam ntxwv ntawm graphite daim hlau. Thaum lub sij hawm noj cov tshuaj, nws yog ib qhov tsim nyog yuav tau ntxiv cov nqi ntawm cov binders, lubricants thiab lwm yam auxiliary cov ntaub ntawv los txhim kho lub formability thiab lub zog ntawm graphite phaj. Kev tsim cov txheej txheem xws li calendering lossis extrusion molding feem ntau yog siv los tsim cov nplooj ntawv graphite ntawm ntau yam tshwj xeeb thiab cov duab. Cov sintering thiab txias txuas ncaj qha txiav txim siab lub cev thiab tshuaj lom neeg ntawm graphite phaj.
Thib peb, lub hauv paus ntsiab lus ntawm kev xaiv cov khoom siv graphite phaj
High Temperature Resistance: Graphite sheets yuav tsum ua haujlwm nyob rau hauv qhov kub thiab txias, yog li nws yog ib qho tsim nyog los xaiv cov khoom uas tuaj yeem tiv taus qhov kub thiab txias. Ntuj flake graphite thiab sib xyaw graphite muaj cov cua sov zoo, thaum cov khoom siv graphite muaj cov cua sov tsis zoo.
Thermal conductivity: Graphite daim hlau yuav tsum muaj cov thermal conductivity zoo heev kom muaj qhov kub thiab txias hauv qhov cub. Ntuj flake graphite thiab sib xyaw graphite muaj cov thermal conductivity zoo, thaum cov khoom graphite muaj cov thermal conductivity tsawg.
Mechanical Strength: Lub graphite phaj yuav tsum muaj qee yam kev siv lub zog los tiv thaiv kev cuam tshuam thiab hnav cov ntaub ntawv hauv lub cub tawg ntawm cov khoom siv. Ntuj flake graphite thiab hybrid graphite muaj lub zog txhua yam, thaum cov khoom siv graphite muaj kev sib piv qis dua txhua yam.
Economical: Raws li cov kev xav tau ntawm kev siv, kev nyiam yuav tsum tau muab rau cov khoom siv nrog tus nqi tsim nyog thiab kev pab lub neej ntev. Tus nqi ntawm ntuj flake graphite yog siab dua, tab sis tus nqi ntawm cov khoom graphite thiab hybrid graphite yog tus nqi qis.
Machinability: Graphite daim hlau yuav tsum tau ua raws li qhov xav tau tiag tiag ntawm kev ua haujlwm, yog li nws yog qhov tsim nyog los xaiv cov ntaub ntawv uas yooj yim rau kev ua haujlwm. Ntuj flake graphite thiab sib xyaw graphite muaj kev ua tau zoo dua, thaum cov khoom siv graphite muaj kev ua haujlwm tsis zoo.
