Itandukaniro riri hagati y'impapuro z'umweru n'ikarito y'umweru agasanduku k'imigati

Impapuro z'umweru ni ubwoko bw'ikarito ifite imbere umweru kandi irambitse hamwe n'inyuma y'umukaraagasanduku ka shokora. Ubwoko bw'ikarito bukoreshwa cyane cyane mu gucapa amabara y'uruhande rumwe kugira ngo hakorwe amakarito yo gupakira. Ingano y'impapuro z'umweru ni 787mm * 1092mm, cyangwa ibindi bisobanuro cyangwa impapuro zishobora gukorwa hakurikijwe amasezerano y'itumiza. Kubera ko imiterere y'impapuro z'umweru z'ikarito isa neza, urwego rw'ubuso rufite ibice byuzuza n'ibya rubber, kandi ubuso butwikiriwe n'irangi runaka, kandi bwatunganyijwe hakoreshejwe uburyo bwo gushushanya imigozi myinshi, bityo imiterere y'ikarito iba ikomeye cyane, kandi ubugari bwayo burangana. Ibyumba byose ni umweru kandi byoroshye, hamwe n'ingufu nyinshi, ivumbi rigabanuka kandi umusatsi utakaza ku buso, ubwiza bw'impapuro burushijeho gukomera kandi bugakomeza kuzingwa neza, ariko amazi arimo ari menshi, muri rusange ari 10%, hari urwego runaka rworoshye, ruzagira ingaruka ku icapiro. Itandukaniro riri hagati y'impapuro z'umweru n'impapuro zitwikiriwe, impapuro za offset, n'impapuro za letterpress ni uko impapuro ziremereye kandi impapuro zikaba nini cyane.gupakira impano ku mpapuro

Impapuro z'umweru zikozwe mu ibumba ryo hejuru na buri cyiciro cy'ibumba ryo hasi ku mashini y'impapuro yumisha imyanda myinshi cyangwa imashini y'urushundura rw'urushundura. Ibumba muri rusange rigabanyijemo ibumba ryo hejuru (urwego rw'ubuso), urwego rwa kabiri, urwego rwa gatatu, n'urwego rwa kane. Igipimo cya fibre cya buri cyiciro cy'ibumba ryo hejuru kiratandukanye, kandi igipimo cya fibre cya buri cyiciro cy'ibumba ryo hejuru giterwa n'uburyo bwo gukora impapuro. Ubwiza buratandukanye. Urwego rwa mbere ni ibumba ryo hejuru, risaba umweru mwinshi n'imbaraga runaka. Ubusanzwe, ibumba ryo hejuru rya kraft ryakuweho cyangwa ibumba ryo hasi rya chemical ryakuweho igice n'ibumba ryo hejuru ry'impapuro z'umweru; urwego rwa kabiri ni urwego rwo hejuru, rukora nk'ubuso bwo kwitandukanya. Uruhare rw'urwego rw'ibanze n'urwego rw'ibanze nabyo bisaba urwego runaka rw'umweru, akenshi hamwe n'ibumba ryo hasi rya 100% ry'imbaho ​​cyangwa ibumba ryo hasi ry'impapuro z'imyanda zifite ibara ryoroheje; urwego rwa gatatu ni urwego rw'ibanze, rukora cyane cyane nk'icyuzuza kugira ngo rwongere ubugari bw'ikariti no kunoza ubukana. Ibumba ryo hasi cyangwa ibumba ryo hasi ryakuweho rikoreshwa. Uru rwego nirwo rukomeye cyane, kandi ikariti ifite uburemere bwinshi ikunze gukoreshwa mu kumanika ibumba inshuro nyinshi mu myanya myinshi y'urushundura; Icyiciro gikurikiraho ni urwego rwo hasi, rufite inshingano zo kunoza imiterere y'ikarito, kongera imbaraga zayo, no gukumira kwizinga. Ikarito ikura cyane cyangwa ikaranze neza ikoreshwa nk'ibikoresho fatizo byo gukora impapuro. Igice cyo hasi cy'ikarito ahanini kiba gifite ibara ry'umukara, kandi andi mabara yo hasi nayo ashobora gukorwa hakurikijwe ibisabwa.agasanduku k'imitako

Ikarito y'umweru ikoreshwa mu gucapa amakarita y'ubucuruzi, ibifuniko, impamyabumenyi, ubutumire no gupakira. Ikarito y'umweru ni impapuro zirambuye, kandi ingano zayo nyamukuru ni: 880mm * 1230mm, 787mm * 1032mm. Dukurikije urwego rw'ubuziranenge, ikarito y'umweru igabanyijemo ibice bitatu: a, B, na C. Ikarito y'umweru ni nini kandi ikomeye, ifite uburemere bunini bw'ibanze, kandi uburemere bwayo bw'ibanze bufite ibisobanuro bitandukanye nka 200 g / m2, 220 g / m2, 250 g / m2, 270 g / m2, 300 g / m2, 400 g / m2 n'ibindi. Uburemere bw'ikarito y'umweru akenshi ntibuba munsi ya 0.80 g / m3, kandi ibisabwa ku buziranenge ni byinshi. Uburemere bw'imiterere ya a, B, na C ntibuba munsi ya 92.0%, 87.0%, na 82.0%, uko bikurikirana. Kugira ngo hirindwe koga, ikarito yera isaba ingano nini, kandi ingano ya a, B, na C ntabwo iri munsi ya mm 1.5, 1.5, na mm 1.0. Kugira ngo ibikoresho by'impapuro bikomeze koroha, ikarito yera igomba kuba nini kandi ikomeye, ifite ubukana bwinshi n'imbaraga nyinshi. Hari ibisabwa bitandukanye kugira ngo amakarito yera abe akomeye kandi afite uburemere butandukanye. Uko uburemere bungana, ni ko urwego rungana, kandi ni ko gukomera kungana. Uko uburemere bungana, ubukana rusange bwo mu burebure ntibugomba kuba munsi ya mN 2.10-10.6, kandi ubukana bwo mu buryo bunyura hejuru ntibugomba kuba munsi ya mN 1.06-5.30.agasanduku ka shokora
