Cov yam ntxwv nthuav dav ntawm expandable graphite flake yog txawv los ntawm lwm yam expansion agents. Thaum rhuab mus rau ib tug tej yam kub, lub expandable graphite pib nthuav vim lub decomposition ntawm cov compounds daig nyob rau hauv lub interlayer lattice, uas yog hu ua thawj expansion kub. Nws nthuav tawm tag nrho ntawm 1000 ℃ thiab ncav cuag nws qhov ntim siab tshaj plaws. Lub ntim nthuav dav tuaj yeem ncav cuag ntau dua 200 npaug ntawm qhov ntim thawj zaug, thiab cov graphite nthuav dav hu ua graphite lossis graphite worm, uas hloov los ntawm cov qub scaly zoo rau cov kab cab uas muaj qhov ntom ntom ntom ntom, tsim cov txheej txheem thermal rwb thaiv tsev zoo heev. Expanded graphite tsis yog tsuas yog cov pa roj carbon qhov chaw nyob rau hauv lub expansion system, tab sis kuj lub rwb thaiv tsev txheej, uas yuav zoo insulate cua sov. Nws muaj cov yam ntxwv ntawm qhov tsis tshua muaj hluav taws xob tso tawm, me me poob thiab tsawg dua cov pa luam yeeb tsim tawm hauv hluav taws. Yog li dab tsi yog cov yam ntxwv ntawm expandable graphite tom qab nws rhuab mus rau hauv nthuav graphite? Nov yog tus editor los qhia nws kom ntxaws:
1, muaj zog tsis kam, yooj, plasticity thiab nws tus kheej lubrication;
2. Tsis tshua muaj kub thiab kub tsis kam, corrosion kuj thiab hluav taws xob tsis kam;
3. Muaj zog seismic yam ntxwv;
4. Cov conductivity siab heev;
5. Muaj zog tiv thaiv kev laus thiab tiv thaiv kev cuam tshuam;
6. Nws tuaj yeem tiv taus cov melting thiab infiltration ntawm ntau yam hlau;
7. Tsis muaj tshuaj lom, tsis muaj carcinogen, thiab tsis muaj kev puas tsuaj rau ib puag ncig.
Qhov nthuav dav ntawm graphite tuaj yeem txo cov thermal conductivity ntawm cov khoom thiab ua tiav cov nplaim hluav taws kub. Yog hais tias lub expandable graphite yog ncaj qha ntxiv, cov carbon txheej txheej tsim tom qab combustion yog twv yuav raug hu tsis ntom. Yog li ntawd, nyob rau hauv industrial ntau lawm, expandable graphite yuav tsum tau ntxiv, uas muaj zoo nplaim retardant nyhuv nyob rau hauv tus txheej txheem ntawm hloov dua siab tshiab rau hauv nthuav graphite thaum rhuab.
