Agasanduku k'impapuro z'itabi ry'urumogi kakozwe mu buryo bwihariye

Ikarito y'umweru ni ubwoko bw'impapuro nini kandi zikomeye kandi zifite uburemere bwinshi. Kubera ko ubuso budafite ibara, bukunze kwitwa ikarito y'umweru. Ikarito y'umweru yo mu Bushinwa igabanyijemo ibice bitatu A, B, C. Ubweru bw'ikarito ya A ntabwo buri munsi ya 92%; B ntabwo buri munsi ya 87%; C ntabwo buri munsi ya 82%.agasanduku k'itabi. agasanduku k'agasanduku k'itabi ka aluminiyumu
Ibikoresho fatizo bya karito y'umweru ni imiti yanduye 100%
Ikarito y'umweru yo gukoresha mu mapaki y'itabi isaba gukomera cyane, kudacika, koroha no kwera. Ibisabwa ku buso bw'impapuro ni ndende, nta mirongo, utudomo, uduce duto, guhindagurika no guhinduka kw'umusaruro. Nk'uko ipaki y'itabi ifite ikarito y'umweru ikoreshwa cyane cyane mu gucapa imashini yihuta cyane, ni nako ibisabwa ku gipimo cy'umuvuduko w'ikarito y'umweru ari byinshi. Ubudahangarwa bw'umuvuduko buzwi kandi nk'imbaraga zo gucika cyangwa imbaraga zo gucika, bivuze imbaraga ntarengwa impapuro zishobora kwihanganira iyo zangiritse, zigaragazwa muri kN/m. Imashini yihuta cyane yo gucapa ikarito kugira ngo ikurure imizingo y'impapuro, gucapa vuba cyane kugira ngo bihangane n'umuvuduko munini, niba ikibazo cyo kwangirika kw'impapuro kenshi, kigomba gutuma igihe cyo kuruhuka gikunze kugabanuka, kugabanya imikorere, ariko nanone bikongera igihombo cy'impapuro.akayunguruzo k'itabi ka mm 6, agasanduku k'ibice 10 karimo udupaki 24
Hari ubwoko bubiri bw'ikarito y'umweru ikoreshwa mu gupfunyika itabi, bumwe ni FBB (ikarita y'umuhondo y'umweru), ubundi ni SBS (ikarita y'umweru y'umweru), udupaki tw'itabi dukoresha FBB na SBS ni ikarito y'umweru ifite uruhande rumwe, FBB igizwe n'ibice bitatu by'umunyu, urwego rwo hejuru n'urwo hasi rukoresha sulfate wood pulp, urwego rwo hejuru rukoresha chemical mechanical slag wood pulp. Uruhande rw'imbere (uruhande rwo gucapa) ni urwego rwo gupfunyika, rukoreshwa n'udupira tubiri cyangwa dutatu, mu gihe uruhande rwo inyuma nta ruhushya rufite rwo gupfunyika. Kubera ko urwego rwo hagati rukozwe mu ruhushya rw'ibiti rukozwe mu buryo bwa shimi n'ubw'ikoranabuhanga, impumuro y'imbaho ​​itanga umusaruro mwinshi (85%-90%), kandi ikiguzi cyo kuyikora ni gito, bityo igiciro cya karito ya FBB ni gito.agasanduku k'itabi ry'ibyatsi. agasanduku k'itabi k'icyuma
Ifu ya FBB ifite imigozi miremire kandi ifite imigozi mito n'udupfunyika duke, bityo ubugari bw'impapuro zirangiye ni bwiza, kandi garama imwe ya FBB ni nini cyane kurusha SBS, nayo isanzwe igizwe n'ibice bitatu bya pulp, urwego rwo hejuru, urwego rw'ibanze n'urwego rwo hasi byose bikoresha pulp ya sulfate ya bleached. Uruhande rw'imbere (uruhande rwo gucapa) ni urwego rwo gusiga, rukoreshwa kabiri cyangwa gatatu hamwe n'umuvuduko umwe na FBB, mu gihe uruhande rw'inyuma nta urwego rwo gusiga rufite. Kubera ko urwego rw'ibanze narwo rukozwe muri pulp ya sulfate ya bleached, umweru uba munini, bityo rwitwa ikarita y'umweru y'ibanze. Muri icyo gihe, imigozi ya pulp ni mito kandi impapuro zirakomeye, bityo SBS ni nto cyane kurusha FBB ifite uburemere bwa garama imwe. Urugero, ubunini bwa 230g/m2 FBB ya Hongta Renheng ni 320μm, mu gihe ubunini bwa 230g/m2 SBS ari 295μm.agasanduku k'itabi gakoreshwa mu gusana. agasanduku k'itabi gasunika amasaro
