Mbere ya byose, ugomba kumenya imiterere y'impapuro zipfutse, hanyuma ukarushaho kumenya ubuhanga bwazo.
Ibiranga impapuro zipfutse:
Ibiranga impapuro zipfutse ni uko ubuso bw'impapuro burushaho kuba bwiza kandi bunoze, bufite uburyohe bwinshi kandi bubengerana neza. Kubera ko umweru w'impapuro zipfutse ukoreshwa urenga 90%, kandi uduce duto cyane, kandi ukozwe mu buryo bwa "super calender", ubusanzwe impapuro zipfutse ni 600-1000. Muri icyo gihe, irangi rikwirakwizwa ku mpapuro kandi rikagaragara nk'umweru ushimishije. Ibisabwa ku mpapuro zipfutse ni uko impapuro zipfutse ziba nto kandi zihuye, nta dupfumu, kandi ingano y'ubudodo mu mpapuro ikwiye kugira ngo hirindwe ko impapuro zikurwamo ifu cyangwa zihinduka mu gihe cyo gucapa. Byongeye kandi, impapuro zipfutse zigomba kuba zifite xylene ikwiye.Agasanduku k'ibiribwa
Gukoresha impapuro zipfutse:
Impapuro zipfutse ni imwe mu mpapuro zikomeye zikoreshwa mu nganda zicapa. Impapuro zipfutse zizwi cyane nka impapuro zipfutse. Zikoreshwa cyane mu buzima busanzwe. Urugero, udusanduku two gupfunyikamo ibiryo, kalendari nziza, ibifuniko by'ibitabo, amashusho, alubumu z'amashusho, icapiro ry'ibikoresho by'ikoranabuhanga mu nganda, hafi ya byose bikoresha impapuro zipfutse, ipaki zishushanyije neza, amasakoshi y'impapuro, ibirango, ikirango cy'ubucuruzi, nibindi. Impapuro zipfutse nazo zikoreshwa ku bwinshi. Impapuro zipfutse zikoreshwa cyane zigabanyijemo ingano zitandukanye kuva kuri garama 70 kuri metero kare kugeza kuri garama 350 kuri metero kare.

Urutonde rw'impapuro zipfutse:
Impapuro zipfundikiye zishobora kugabanywamo impapuro zipfundikiye zifite impande imwe, impapuro zipfundikiye zifite impande ebyiri, impapuro zipfundikiye zifite matte n'impapuro zipfundikiye. Dukurikije ubwiza, zigabanyijemo ibice bitatu A, B, C. Ibikoresho by'ingenzi by'impapuro zipfundikiye ni impapuro zipfundikiye zifite irangi. Ibisabwa ku mpapuro zipfundikiye zifite irangi ry'ubugari bungana, ubushobozi buke bwo koroha, imbaraga nyinshi no kwirinda amazi neza. Nta bizinga, iminkanyari, imyobo n'ibindi bibazo by'impapuro bigomba kuba ku buso bw'impapuro. Igitambaro gikoreshwa mu gupfundikira kigizwe n'amabara y'umweru meza (nka kaolini, barium sulfate, nibindi), kole (nka polyvinyl alcohol, casein, nibindi) n'inyongera z'inyongera.

Imiterere y'impapuro zipfutse:
Impapuro zipfundikiye zifite impapuro zirambuye n'impapuro zizunguruka. Impapuro zipfundikiye zikozwe mu giti cya bleached chemical pulp cyangwa bleached chemical straw pulp ku mashini y'impapuro. Impapuro zipfundikiye ni zo zipfundikiye, amarangi yera (azwi kandi nk'ibumba, nka kaolini, talc, calcium carbonate, titanium dioxide, nibindi), kole (polyvinyl alcohol, casein, modified starch, synthetic latex, nibindi), nibindi bikoresho by'inyongera (nk'ibikoresho by'ubukonje, ibikoresho bikomeye, plasticizers, dispersants, ibikoresho byo kunywesha, ibikoresho bya opalescent, ibikoresho by'ubukonje bw'amatara, toners, nibindi), bipfundikiye ku mashini ipfundikira, kandi byumye kandi bikozwe mu buryo bwa super calendered. Ubwiza bw'impapuro ni bumwe kandi buhamye, umweru ni munini (hejuru ya 85%), ubuso bw'impapuro buraryoshye kandi burabagirana, kandi igipfundikizo kirakomeye kandi gihoraho.Agasanduku k'ibikombe
