Impapuro z'ubutabazi

impapuro nyamukuru zikoreshwa mubutabazi bwo gucapa ibitabo nibinyamakuru. Bikwiranye nibikorwa byingenzi, ibitabo bya siyansi nikoranabuhanga, ibinyamakuru byigisha nibikoresho byigisha, nkimpapuro. Impapuro zubutabazi ukurikije ibigize impapuro zirashobora kugabanywamo amanota 1,2,3 na 4. Umubare wimpapuro mu izina ryubwiza bwimpapuro, niko umubare wimpapuro uba mubi. Impapuro zo gucapa impapuro zikoreshwa cyane cyane mugucapa ubutabazi. Ibiranga iyi mpapuro birasa namakuru yamakuru, ariko ntabwo arimwe. Imiterere yimpapuro zubutabazi zirasa cyane, mugihe kimwe, icyuho kiri hagati ya fibre cyuzuzwa numubare wuzuye wuzuza na reberi, kandi na nyuma yo guhumeka, bigize iyi mpapuro bifite uburyo bwiza bwo guhuza no gucapa. Nubwo kwinjiza wino kwayo atari byiza nkibinyamakuru, ariko bifite imiterere imwe yo kwinjiza wino, kurwanya amazi no kwera impapuro biruta ibinyamakuru.

Ikinyamakuru

Nyuma ya kalendari, impande zombi zimpapuro ziroroshye kandi ntizisukuye, kuburyo impande zombi zanditseho bigaragara neza kandi byuzuye; hari urwego runaka rwimbaraga za mashini; ububobere bwiza; bikwiranye no kwihuta kwihuta. Ubu bwoko bwimpapuro bukozwe mubiti bya mashini (cyangwa ubundi buryo bwa chimique), burimo umubare munini wa Lignin nibindi byanduye, ntibikwiriye kubikwa igihe kirekire. Igihe cyo kubika ni kirekire cyane, impapuro zizaba umuhondo Brittle, kutarwanya amazi, ntibikwiriye kwandika.
