Cov nyhuv thiab cov khoom zoo ntawm cov khoom graphite

Vim nws cov khoom zoo heev, graphite pom kev siv dav hauv metallurgical, mechanical, electronics, chemical, textile, and other industrial sectors. Nws ua hauj lwm raws li cov khoom siv refractory thiab khaws cov tshuaj qub qub ntawm flake graphite thaum nthuav tawm cov khoom zoo ntawm tus kheej lubricating. Graphite hmoov yog tus cwj pwm los ntawm lub zog siab acid tsis kam, tiv thaiv corrosion, siab kub siab siab txog 3000 ℃ thiab qis kub resilience mus rau -204 ℃. Tsis tas li ntawd, nws boasts lub zog compressive tshaj 800kg / Cm2 thiab qhia oxidation tsis kam nrog tsuas yog 1% yuag poob thaum raug huab cua ntawm 450 ℃. Tsis tas li ntawd, nws nthuav tawm tus nqi rov qab ntawm 15-50% (qhov ceev 1.1-1.5). Yog li ntawd, graphite cov khoom siv dav siv hauv metallurgy, tshuaj lom neeg kev lag luam, kev lag luam petrochemical, siab zog physics, aerospace, electronics thiab ntau yam kev lag luam.

Graphite khoom lawv tus kheej muaj qhov zoo heev:

1, graphite khoom muaj adsorption zoo.

Cov qauv void ntawm carbon ua rau cov pa roj carbon zoo adsorption, yog li carbon feem ntau yog siv los ua cov khoom siv adsorption rau nqus dej, tsw ntxhiab, tshuaj lom thiab lwm yam. Peb tau ua qhov kev sim, ob peb hnub dhau los barbecue siv graphite ci tais zoo li huv si, tab sis muab tso rau ntawm qhov cub induction cua sov, koj yuav pom qhov kawg barbecue adsorption ntawm roj thiab cov khoom tsis zoo yuav maj mam ooze tawm, tab sis tsis txhob txhawj, nrog ib tug huv daim ntawv so kom huv yuav siv tau.

2, graphite cov khoom muaj cov thermal conductivity zoo, hloov hluav taws xob sai, cov cua sov tsis zoo, txuag roj.

Cov nplooj ntawv ci thiab cov lauj kaub ua los ntawm graphite yog rhuab sai sai, thiab cov khoom noj raug rho tawm yog rhuab sib npaug, siav los ntawm sab hauv, thiab lub sij hawm cua sov yog luv luv, tsis tsuas yog saj yog ntshiab, tab sis kuj tseem cov khoom noj khoom haus qub ntawm cov zaub mov tuaj yeem kaw. . Peb tau ua cov kev sim, thaum lub graphite grill lauj kaub yog siv rau roasting, lub induction cooker ntaus qhov hluav taws kub thaum pib, thiab nws muaj peev xwm yuav preheated nyob rau hauv tsuas yog 20-30 vib nas this, thiab thaum cov zaub mov pib, nws yuav ua si rau ib tug hluav taws me me, uas tuaj yeem txuag hluav taws xob.

3, graphite cov khoom muaj tshuaj stability thiab corrosion kuj.

Graphite muaj cov tshuaj zoo ruaj khov ntawm chav tsev kub thiab tsis raug tawm tsam los ntawm cov kua qaub uas muaj zog, muaj zog hauv paus thiab cov kuab tshuaj organic. Yog li ntawd, txawm tias kev siv cov khoom siv graphite mus sij hawm ntev yog qhov poob qis heev, tsuav nws yog wiped huv si li tshiab.

4 graphite khoom muaj zog tiv thaiv oxidation thiab txo cov nyhuv.

Cov khoom lag luam, tshwj xeeb tshaj yog cov graphite txaj cua sov tuaj yeem tsim cov pa oxygen ions tsis zoo, ua rau cov khoom nyob ib puag ncig muaj zog, tswj tib neeg kev noj qab haus huv, tiv thaiv kev laus, ua rau daim tawv nqaij ua kom lub ntsej muag thiab elasticity.

5, graphite khoom ib puag ncig kev noj qab haus huv, tsis muaj hluav taws xob muaj kuab paug, kub tsis kam.

Cov pa roj carbon monoxide tuaj yeem dhau los ua graphite tom qab tsawg kawg kaum hnub thiab hmo ntuj ntawm graphitization nyob rau hauv qhov kub thiab txias ntawm 2000-3300 degrees, yog li cov tshuaj lom thiab teeb meem hauv graphite tau tso tawm ntev thiab ruaj khov nyob rau hauv tsawg kawg yog 2000 degrees.

Nyob rau tib lub sijhawm, cov khoom lag luam graphite vim nws cov qauv tshwj xeeb, nrog rau qhov kub thiab txias tsis kam, thermal shock resistance, hluav taws xob conductivity, lubrication, tshuaj stability thiab plasticity thiab ntau lwm yam ntxwv, yog ib qho tseem ceeb ntawm kev tsim cov tub rog thiab niaj hnub kev lag luam. thiab siab, tshiab thiab ntse technology, graphite khoom, xws li graphite rings, graphite nkoj yog dav siv. Cov kws tshaj lij thoob ntiaj teb tau kwv yees tias "xyoo pua 20th yog lub xyoo pua ntawm silicon, lub xyoo pua 21st yuav yog xyoo pua ntawm carbon."

Raws li ib qho tseem ceeb ntawm cov khoom lag luam uas tsis yog hlau tsis muaj hlau, kev lag luam graphite yuav raug siv los tswj kev nkag. Nrog rau kev siv ntawm kev nkag mus, graphite, graphite cov khoom, yuav dhau los ua lwm yam tom qab lub ntiaj teb tsis tshua muaj, tshuaj fluorine, phosphorus tshuaj, cov tuam txhab ua lag luam hauv daim teb no yuav nkag mus rau theem tshiab ntawm kev txhim kho.
