1. Expandable graphite tuaj yeem txhim kho qhov kub thiab txias ntawm cov khoom siv hluav taws xob.
Hauv kev tsim khoom lag luam, txoj kev siv feem ntau yog ntxiv cov nplaim hluav taws xob rau hauv engineering plastics, tab sis vim qhov kub tsis tshua muaj decomposition, decomposition yuav tshwm sim ua ntej, ua rau tsis ua hauj lwm. Lub cev muaj zog ntawm expandable graphite yog ruaj khov, uas yuav tsis cuam tshuam rau qhov zoo ntawm cov ntaub ntawv ua tiav thiab txhim kho cov nplaim hluav taws.
Dab tsi yog qhov zoo ntawm expandable graphite?
Expandable graphite
2. Cov pa luam yeeb uas tsim los ntawm expandable graphite yog tsawg thiab cov nyhuv tseem ceeb.
Feem ntau hais lus, halogenated nplaim retardants yuav muab ntxiv los ua cov khoom nplaim hluav taws thiab nplaim hluav taws ua haujlwm, tab sis yuav tsim cov pa taws thiab cov kua qaub, cuam tshuam rau tib neeg kev noj qab haus huv, corrosion ntawm cov khoom siv sab hauv tsev; Hlau hydroxide kuj tseem yuav ntxiv, tab sis nws muaj kev cuam tshuam zoo rau kev cuam tshuam thiab kev siv lub zog ntawm cov yas lossis matrix, thiab tuaj yeem cuam tshuam rau tib neeg kev noj qab haus huv thiab corrode cov khoom siv sab hauv tsev. Thaum huab cua tsis du heev, ntxiv phosphorous nplaim retardants tuaj yeem cuam tshuam rau tib neeg. Expandable graphite yog qhov zoo tagnrho. Nws tsim cov pa luam yeeb me me thiab muaj cov nplaim hluav taws kub hnyiab.
3. Expandable graphite muaj zoo rwb thaiv tsev kub thiab corrosion kuj.
Expandable graphite yog cov khoom siv corrosion-resistant uas muaj nyob rau hauv cov siv lead ua ruaj khov. Nws tsis deteriorate thaum lub sij hawm decomposition thiab oxidation kom txog thaum nws tsis ua hauj lwm vim muaj kev txwv ntawm txee lub neej thiab stability.
Nyob rau hauv cov ntsiab lus, qhov zoo ntawm expandable graphite ua rau nws cov khoom ntawm kev xaiv rau tshav kub rwb thaiv tsev thiab nplaim retardant. Thaum xaiv cov graphite nthuav dav, peb yuav tsum xaiv cov khoom lag luam zoo graphite kom ua tiav cov txiaj ntsig kev lag luam, tsis yog rau tus nqi qis xwb.
