Brazil Txoj Kev Loj Hlob Ntawm Lwm Tiam Super-Graphene muaj zog- cov khoom siv ntxiv tuaj yeem txuag tau 30% ntawm cov khoom siv raw

Gerdau Graphene, lub tuam txhab nanotechnology uas muab cov graphene siab heev- cov ntaub ntawv siv zog rau kev siv hauv kev lag luam, tshaj tawm tias nws tau tsim cov graphene tiam tom ntej - cov khoom siv ntxiv ntawm cov khoom siv siab heev uas tau txais nyiaj los ntawm tsoomfwv Brazilian hauv Sao Paulo, Brazil, Qhov tshiab graphene no - siv zog ntxiv polymeric formulation PP (PP) polypropylene masterbatch tsim nyob rau hauv kev koom tes nrog Advanced Materials Division ntawm EMBRAPII SENAI / SP hauv Brazil thiab tam sim no tab tom tab tom ua ib qho kev sim ua haujlwm ntawm Gerdau Graphene lub Hoobkas. Cov khoom siv thermoplastic tshiab uas tsim los siv cov qauv no yuav muaj zog dua thiab muab kev ua haujlwm zoo dua qub, thaum tib lub sijhawm pheej yig dua los tsim thiab tsim cov khoom pov tseg tsawg dua thoob plaws hauv cov saw hlau.

Graphene, suav tias yog cov khoom muaj zog tshaj plaws hauv ntiaj teb, yog cov ntawv tuab ntawm cov pa roj carbon monoxide ntawm ib thiab 10 atoms tuab uas tuaj yeem hloov kho rau ntau yam kev siv thiab ntxiv rau cov khoom siv. Txij li thaum nws nrhiav tau nyob rau hauv 2004, graphene cov tshuaj txawv tshaj plaw, lub cev, hluav taws xob, thermal thiab mechanical zog tau nyiam thoob ntiaj teb kev saib xyuas, thiab nws cov neeg nrhiav pom tau txais khoom plig Nobel hauv Chemistry. Graphene tuaj yeem sib xyaw nrog cov yas kom muab nws lub zog zoo kawg, ua rau cov yas sib xyaw ua ke muaj zog dua. Ntxiv nrog rau kev txhim kho lub cev thiab cov khoom siv kho tshuab, graphene tuaj yeem txhim kho nws cov khoom thaiv kev tiv thaiv cov kua thiab roj, tiv thaiv huab cua, oxidation thiab ultraviolet lub teeb, thiab txhim kho hluav taws xob thiab thermal conductivity.

Gerdau Graphene tab tom tsim Graphene additives rau haiv neeg resins nrog rau kev tshaj tawm -cov neeg siv khoom siv cov yas thiab polymers, suav nrog PP, PE, PS, PC thiab PVC, thiab lwm yam. Hauv Tebchaws Meskas ib leeg, kwv yees li 8 lab tons ntawm PP thiab 23 lab tons ntawm PE raug tsim txhua xyoo. Kev txo qis 30% ntawm cov khoom siv PP thiab PE uas xav tau los ua cov khoom yas zaum kawg no yuav txhais tau tias 9.3 lab tons ntawm PP thiab PE yas yuav raug siv thiab thaum kawg muab pov tseg txhua xyoo.

"Plastics yog ib qho tseem ceeb raw khoom. Tam sim no, yuav luag tag nrho cov khoom nyob rau hauv ntau yam industries nyob rau hauv lub ntiaj teb no yog inseparable los ntawm yas cov ntaub ntawv. Nws invention tau kiag li hloov txoj kev ntawm tib neeg lub neej. Peb qhov kev sib tw loj tshaj plaws yog yuav ua li cas kom plastics zoo dua los ntawm kev txhim kho cov khoom zoo, txo tus nqi thiab nce kev ruaj ntseg ntawm tag nrho lub neej voj voog, thiab tam sim no peb ua tiav tag nrho cov hom phiaj. " Alexandre Correa, CEO ntawm Gerdau Graphene, tau hais tias, 'Los ntawm kev ntxiv Graphene tshwj xeeb ntxiv rau cov qauv thermoplastic, cov tuam txhab yas tuaj yeem tsim cov khoom yas muaj zog thiab ruaj khov dua ntawm tus nqi qis, thaum siv roj tsawg thiab cov khoom siv raw. Vim tias cov yas tsawg dua yuav tsum tau tsim cov khoom kawg, cov yas tsawg dua mus pov tseg tom qab noj. Kuj tseem muaj kev cuam tshuam hauv qab dej, suav nrog txo cov khoom pov tseg, kev siv hluav taws xob thiab nqi tsheb thauj mus los. Thiab nyob rau hauv kev lag luam ncig, nyob rau yav tom ntej, graphene tuaj yeem muab rho tawm los ntawm cov yas rov siv dua thiab rov siv dua. "
