Kusiyana pakati pa white board paper ndi white cardboard bokosi la makeke

White board paper ndi mtundu wa makatoni okhala ndi kutsogolo koyera ndi kosalala ndi imvi kumbuyobokosi la chokoleti. Makatoni amtunduwu amagwiritsidwa ntchito makamaka posindikiza mtundu wa mbali imodzi kupanga makatoni olongedza. Kukula kwa pepala loyera ndi 787mm * 1092mm, kapena zolemba zina kapena pepala lodzigudubuza litha kupangidwa molingana ndi mgwirizano. Chifukwa mawonekedwe a ulusi wa pepala loyera ndi lofanana, pamwamba pake amakhala ndi zodzaza ndi mphira, ndipo pamwamba pake amakutidwa ndi utoto winawake, ndipo amakonzedwa ndi ma multi-roller calendering, kotero mawonekedwe a bolodi amapangidwa. ndi zothina, ndipo makulidwe ake ndi ofanana. Milandu yonse imakhala yoyera komanso yosalala, yokhala ndi mayamwidwe a inki yunifolomu, kufumbi pang'ono komanso kutayika kwa tsitsi pamtunda, mtundu wamphamvu wa pepala komanso kukana bwino kumapinda, koma madzi ake ndi apamwamba, nthawi zambiri pa 10%, pali kusinthasintha kwina, zomwe zidzakhudza kwambiri kusindikiza. Kusiyanitsa pakati pa pepala loyera ndi pepala lophimbidwa, pepala la offset, ndi pepala la letterpress ndilokuti pepala ndi lolemera ndipo pepala ndi lalikulu.mapepala-mphatso-kuyika

Pepala loyera loyera limapangidwa ndi zamkati pamwamba ndi gawo lililonse la zamkati pansi pamakina angapo owumitsira mapepala ambiri kapena makina ophatikizika a ukonde ozungulira. Zamkati nthawi zambiri zimagawidwa kukhala zamkati (zosanjikiza pamwamba), wosanjikiza wachiwiri, wosanjikiza wachitatu, ndi wachinayi. Chiŵerengero cha CHIKWANGWANI cha wosanjikiza uliwonse wa zamkati wa pepala ndi wosiyana, ndipo chiŵerengero cha CHIKWANGWANI cha chigawo chilichonse cha zamkati chimadalira pakupanga mapepala. Ubwino umasiyanasiyana. Woyamba wosanjikiza ndi zamkati pamwamba, amene amafuna woyera mkulu ndi mphamvu zina. Nthawi zambiri, bleached kraft nkhuni zamkati kapena bleached pang'ono mankhwala udzu zamkati ndi woyera pepala m'mphepete zinyalala zamkati zamkati ntchito; wachiwiri wosanjikiza ndi akalowa wosanjikiza, amene amakhala ngati kudzipatula pamwamba Udindo wa pachimake wosanjikiza ndi pachimake wosanjikiza amafunanso mlingo wina wa whiteness, kawirikawiri ndi 100% makina matabwa zamkati kapena kuwala kowala zinyalala pepala zamkati; wachitatu wosanjikiza ndi pachimake wosanjikiza, amene makamaka amachita monga kudzazidwa kuonjezera makulidwe a makatoni ndi kusintha kuuma. Zosakaniza zotayira mapepala zamkati kapena zamkati za udzu zimagwiritsidwa ntchito. Chosanjikiza ichi ndi chokhuthala kwambiri, ndipo makatoni okhala ndi kulemera kwakukulu amagwiritsidwa ntchito kupachika zamkati kangapo m'mipata yambiri ya mauna; mzere wotsatira ndi wosanjikiza wapansi, womwe uli ndi ntchito zowonjezera maonekedwe a makatoni, kuwonjezera mphamvu zake, ndikuletsa kupindika. Zamkati zokolola zambiri kapena zotayira bwino zamapepala zimagwiritsidwa ntchito ngati zida zopangira mapepala. Pansi pa makatoni nthawi zambiri imakhala imvi, ndipo mitundu ina yapansi imatha kupangidwanso malinga ndi zofunikira.bokosi la zodzikongoletsera

Makatoni oyera amagwiritsidwa ntchito kusindikiza makhadi abizinesi, zofunda, ziphaso, zoyitanira ndi kuyika. Makatoni oyera ndi pepala lathyathyathya, ndipo miyeso yake yayikulu ndi: 880mm * 1230mm, 787mm * 1032mm. Malingana ndi msinkhu wa khalidwe, makatoni oyera amagawidwa m'magulu atatu: a, B, ndi C. Makatoni oyera ndi okulirapo komanso olimba, okhala ndi kulemera kwakukulu, ndipo kulemera kwake kumakhala ndi zizindikiro zosiyanasiyana monga 200 g / m2, 220. g/m2, 250 g/m2, 270 g/m2, 300 g/m2, 400 g/m2 ndi zina zotero. Kuthina kwa makatoni oyera nthawi zambiri sikuchepera 0.80 g/m3, ndipo zofunikira zoyera ndizokwera kwambiri. Kuyera kwa magiredi a, B, ndi C sikuchepera 92.0%, 87.0%, ndi 82.0%, motsatana. Pofuna kupewa kusambira, makatoni oyera amafunikira digiri yokulirapo, ndipo magawo a, B, ndi C sachepera 1.5mm, 1.5mm, ndi 1.0mm motsatana. Pofuna kusunga kusalala kwa mapepala a mapepala, makatoni oyera ayenera kukhala ochuluka komanso olimba, olimba kwambiri komanso mphamvu zophulika. Pali zofunikira zosiyanasiyana za kuuma kwa makatoni oyera amitundu yosiyanasiyana ndi zolemera. Kulemera kwake kwakukulu, kumakwera giredi, ndipo kumakwera kuuma. Kukakamira kofunikirako kukulirakulira, kuuma kwautali kwanthawi yayitali sikuyenera kuchepera 2.10-10.6mN•m, komanso kuuma kopingasa sikuyenera kuchepera 1.06-5.30 mN•m.bokosi la chokoleti
