\nDup\u0103 ce au inventat h\u00e2rtia acum aproape 2.000 de ani, chinezii au dezvoltat acum o versiune \u00eembun\u0103t\u0103\u0163it\u0103 a acestui material, potrivit go4it.ro.<\/p>\n
\nO echip\u0103 de cercet\u0103tori de la Institutul de Ceramic\u0103 din Shanghai a prezentat h\u00e2rtia rezistent\u0103 la ap\u0103 \u015fi foc. Nici petele provocate de lichide precum cafeaua sau ceaiul nu sunt o problem\u0103 pentru aceasta.<\/p>\n
\nMai mult, noul tip de h\u00e2rtie rezist\u0103 la temperaturi de p\u00e2n\u0103 la 200 de grade Celsius. Totodat\u0103, materialul poate fi cur\u0103\u0163at cu ap\u0103 f\u0103r\u0103 ca scrisul de pe el s\u0103 se deterioreze.<\/p>\n
Noul tip de h\u00e2rtie este realizat din nanofibre de hidroxipatit, o form\u0103 de calciu care se g\u0103se\u015fte \u00een oase \u015fi din\u0163i. H\u00e2rtia este de obicei fabricat\u0103 din pulp\u0103 lemnoas\u0103.<\/p>\n
\nH\u00e2rtia a fost inventat\u0103 de chinezi \u00een jurul anului 105. Abia \u00een secolul 11 acest me\u015fte\u015fug a ajuns \u015fi \u00een Europa. \u00cen secolul 16, h\u00e2rtia a \u00eenceput s\u0103 fie confec\u0163ionat\u0103, printr-un procedeu mai simplu, din pulp\u0103 lemnoas\u0103, fapt care a dus la r\u0103sp\u00e2ndirea mai rapid\u0103 a cuno\u015ftin\u0163elor \u00een lume.<\/p>\n","protected":false},"excerpt":{"rendered":"
