Mbiri ya pepala ndi mbiri ya chitukuko cha anthu. Kuchokera pakuwonekera kwa pepala ku Western Han Dynasty, kupita patsogolo kwa kupanga mapepala ndi Cai Lun mu Dynasty ya Kum'mawa kwa Han, ndipo tsopano, mapepala salinso chonyamulira cholembera, komanso angagwiritsidwe ntchito pazinthu zina monga kusindikiza, kulongedza katundu, mafakitale, ndi moyo.
M'nkhaniyi, tiyeni tiwone mfundo zazikuluzikulu zowunikira / kuyang'anira ndi zigamulo zomwe zimafanana ndi zomwe zili pamapepala.
Kuchuluka kwa ntchito
Zogulitsa zomwe malangizowa akugwiritsidwa ntchito ndi: mapepala a chikhalidwe, mapepala aukadaulo a mafakitale ndi zaulimi, mapepala oyikapo ndi mapepala apanyumba. Mapepala otumizidwa kunja kwa dziko langa ndi mapepala a chikhalidwe (manyuzipepala, mapepala okutidwa, mapepala otsekemera, mapepala olembera) ndi mapepala olongedza (kraft cardboard, white cardboard, corrugated base paper, white cardboard, cellophane, etc.).

Mfundo yofunika: Zofunikira za pepala ndizosiyana malinga ndi gulu
Newsprint: Newsprint imafuna pepala kuti likhale lofewa komanso lokhazikika, ndipo pamwamba pa pepala liyenera kukhala ndi absorbency kwambiri. Kuonetsetsa kuti inki yosindikiza ikhoza kuuma mwamsanga panthawi yosindikiza. Zimafunika kuti mbali ziwiri za pepalalo zikhale zosalala, makulidwe ake ndi ofanana, mawonekedwe ake ndi abwino, kusindikiza kulibe lint, sikumangirira mbale, chitsanzocho ndi chomveka, ndipo palibe cholakwika chilichonse. Pa pepala lopunthira, mbali ziwiri za mpukutuwo zimafunikira kuti zikhale zothina chimodzimodzi, zolumikizira zochepa, ndi mphamvu zokhazikika bwino, kuti zikwaniritse zofunikira zosindikizira zamakina osindikizira othamanga kwambiri.
Zofunikira pamapepala okutidwa: kusalala. Pamwamba pa mapepala ayenera kukhala osalala kwambiri, kotero kuti akhoza kukhudzana kwathunthu ndi pamwamba pa chinsalu mbale yamkuwa pa kusindikiza, kuti apeze zabwino ndi zomveka bwino mizere yopyapyala, yomwe imakhala yowoneka bwino komanso yosangalatsa m'maso.
Pepala loyera: Pepala loyera nthawi zambiri limafunikira mawonekedwe olimba, osalala pamwamba, makulidwe osasinthasintha, osapanganso nsalu pamwamba pa pepala, kuyamwa bwino komanso kachulukidwe kakang'ono kuti akwaniritse zofunikira pakusindikiza kwamitundu yambiri. Kuti akwaniritse zofunikira pakupanga bokosi, pepala loyera loyera liyenera kukhala ndi mawonekedwe owuma kwambiri komanso kukana mwamphamvu kupindika.
Makatoni a Kraft: Makatoni a Kraft ndi makatoni omwe amagwiritsidwa ntchito makamaka pakuyika zinthu zakunja, kotero kapangidwe ka pepala kuyenera kukhala kolimba, ndipo mphamvu yophulika, mphamvu yopondereza ya mphete ndi digiri yong'ambika iyenera kukhala yayikulu. Kuphatikiza apo, iyenera kukhala ndi kukana kwamadzi kwakukulu, kuti mphamvuyo isachepetse kwambiri chifukwa cha kuchuluka kwa chinyezi, zomwe zimapangitsa kuwonongeka kwa katoni panthawi yoyendetsa nyanja kapena kusungirako kuzizira. Iyeneranso kukhala ndi kusalala kwina kwa makatoni a kraft omwe amafunika kugwiritsidwa ntchito posindikiza.
Pepala lokhala ndi malata: Pepala lokhala ndi malata limafunikira mphamvu yabwino yomangirira ulusi, mapepala osalala, komanso kulimba kwambiri komanso kuuma. Kuchuluka kwa mphamvu kumafunika kuti katoni yopangidwa ikhale yosasunthika komanso yosasunthika. Chifukwa chake, kuphulika kwamphamvu ndi mphamvu yopondereza ya mphete (kapena mphamvu yopondereza) ndizizindikiro zazikulu zomwe zikuwonetsa kulimba kwa pepala lokhala ndi malata. Kuphatikiza apo, index ya chinyezi iyeneranso kuyendetsedwa. Ngati chinyezi chili chochepa kwambiri, pepalalo lidzakhala lolimba, ndipo kusweka kudzachitika panthawi ya corrugating. Kuchuluka kwa madzi kumabweretsa zovuta pakukonza. Nthawi zambiri, chinyezi chiyenera kukhala pafupifupi 10%.
Cellophane: Cellophane ndi yowonekera mumtundu, yowala pamapepala, yunifolomu mu makulidwe, yofewa komanso yotambasuka. Zimatupa ndi kufewa zitaviikidwa m'madzi, ndipo zimachepa mwachibadwa pambuyo poumitsa. Kuonjezera apo, chifukwa cha kufanana kwa ma microcrystals a cellulose mumayendedwe a nthawi yayitali, mphamvu yayitali ya pepala ndi yaikulu, ndipo njira yodutsayi ndi yaying'ono, ndipo ngati pali mng'alu, idzaphwanyidwa ndi mphamvu yochepa kwambiri. Cellophane ali ndi katundu wa impermeability, mafuta impermeability ndi madzi impermeability.
Mapepala osindikizira a Offset: Mapepala a Offset amagwiritsidwa ntchito posindikiza mitundu yambiri. Kuphatikiza pa kufuna kuyera bwino komanso fumbi locheperako, ilinso ndi zofunikira zapamwamba pakulimba kwa mapepala, kulimba kwamphamvu komanso kupindika kupindika. Pakusindikiza, pamwamba pa pepala samatulutsa lint, ufa, kapena kusindikiza. Lili ndi zofunikira zofanana ndi mapepala okutidwa.
