Expandable graphite hmoovyog cov khoom siv qib siab carbon-raws li paub txog nws lub peev xwm tshwj xeeb kom nthuav dav sai thaum raug kub hnyiab. Cov cuab yeej thermal expansion no ua rau nws xaiv zoo rau cov ntawv thov hauv hluav taws kub, metallurgy, roj teeb tsim, thiab cov ntaub ntawv sib khi.
Dab tsi yog Expandable Graphite Powder?
Expandable graphite yog ib daim ntawv ntawm ntuj graphite uas tau raug tshuaj kho nrog acids thiab oxidizing tus neeg sawv cev. Thaum rhuab mus rau qhov kub thiab txias (feem ntau siab dua 200-300 ° C), cov khoom nthuav dav heev raws nws cov c-axis, tsim lub teeb yuag, zoo li cov kab mob hu ua graphite worms. Qhov kev nthuav dav no tuaj yeem nce qhov ntim thawj zaug txog 200-300 zaug.
Cov yam ntxwv tseem ceeb thiab qhov zoo
Superior nplaim taws Retardancy: Expandable graphite tsim ib txheej insulating char txheej thaum raug hluav taws, zoo thaiv tshav kub, oxygen, thiab nplaim taws gases. Nws yog dav siv nyob rau hauv intumescent txheej, fireproof boards, thiab cables.
High Purity thiab Stability: Muaj nyob rau hauv cov qib sib txawv, nrog rau cov ntaub ntawv siab purity haum rau kev siv hluav taws xob, nuclear, thiab roj teeb.
Ib puag ncig kev nyab xeeb: Raws li cov nplaim hluav taws tsis muaj halogen, expandable graphite yog ib qho kev nyab xeeb dua rau cov tshuaj tua hluav taws retardants.
Tshuaj thiab Thermal Resistance: Kev tiv thaiv zoo rau cov kua qaub, cov hauv paus, thiab qhov kub thiab txias ua rau nws tsim nyog rau qhov chaw hnyav.
Customizable Expansion Rate: Lub ntim nthuav dav, pib qhov kub thiab txias tuaj yeem ua kom haum raws li cov kev xav tau tshwj xeeb.
Cov ntawv thov siv
Hluav taws kub Retardant Additives: Hauv plastics, foams, textiles, roj hmab, thiab cov khoom siv.
Kev lag luam metallurgical: Raws li ib tug recarburizer thiab rwb thaiv tsev cov ntaub ntawv nyob rau hauv steelmaking.
Sealing Gaskets: Siv nyob rau hauv kev lag luam automotive thiab petrochemical rau kev ua haujlwm siab.
Cov khoom siv roj teeb: Siv rau hauv kev tsim cov khoom siv anode rau cov roj teeb lithium-ion.
Graphite ntawv thiab Foils: Expanded graphite tuaj yeem nias rau hauv cov nplooj ntawv hloov tau siv rau hauv cov khoom siv hluav taws xob thiab cov khoom cua sov.
Xaus
Expandable graphite hmoov yog cov khoom siv ntau yam nrog kev xav tau hauv kev lag luam uas xav tau cov nplaim hluav taws xob ua haujlwm siab, cov khoom siv siab heev, thiab cov kev daws teeb meem zoo ib puag ncig. Txawm hais tias koj tab tom tsim cov khoom siv hluav taws xob hauv tsev lossis cov khoom siv hluav taws xob high-end, graphite expandable muaj kev ua tau zoo, kev nyab xeeb, thiab ntau yam.
