Pepala lomwe likufunika kukonzedwa ndi pepala loyambira. Mwachitsanzo, pepala lophatikizika lomwe limagwiritsidwa ntchito kusindikiza, mapepala ophatikizika amatha kutchedwa pepala loyambira posindikiza; Makatoni oyera omwe amagwiritsidwa ntchito popanga mapepala amathanso kutchedwa pepala loyambira la pepala lophatikizana.
I. Lingaliro la pepala loyambira
Pepala loyambira limatanthawuza mapepala osasinthidwa, omwe amadziwikanso kuti master roll. Nthawi zambiri zopangidwa ndi matabwa kapena zinyalala pepala ndi zina CHIKWANGWANI zopangira, ndi ndondomeko pepala processing. Malinga ndi zida zosiyanasiyana komanso njira zopangira, mapepala oyambira amakhala ndi mitundu yosiyanasiyana komanso mawonekedwe.
II. Mitundu ya pepala loyambira
Malinga ndi zida zosiyanasiyana zopangira, mapepala oyambira amatha kugawidwa m'mapepala oyambira amatabwa ndi mapepala otayira amitundu iwiri.
1. Wood zamkati m'munsi pepala
Mapepala amtundu wa matabwa amagawidwa kukhala mapepala a softwood pulp base and hardwood zamkati. Mapepala a Softwood pulp base amapangidwa ndi matabwa a softwood, oyenera kupanga mapepala osindikizira mabuku, mapepala okutira, ndi zina zotero. Mapepala oyambira a matabwa olimba amapangidwa ndi matabwa olimba ndipo ndi oyenera kupanga zipangizo zonyamula katundu monga makatoni a malata.
2. Kutaya mapepala oyambira
Pepala lotayidwa pansi limapangidwa ndi pepala lotayirira ngati zopangira. Malinga ndi mitundu ya pepala lotayirira komanso kuchuluka kwa ntchito, pepala lotayirira lotayidwa limagawidwa kukhala makatoni oyera, mapepala a kraft, pepala la fodya, nyuzipepala ndi mitundu ina.
III. Kugwiritsa ntchito pepala loyambira
Mapepala oyambira ndi chinthu chofunikira kwambiri chopangira mapepala, chomwe chimagwiritsidwa ntchito m'mabuku, magazini, zonyamula, zaukhondo, zolembera, zomangira ndi zina. Malinga ndi kugwiritsa ntchito ndi zosowa zosiyanasiyana, mapepala oyambira amatha kukhala amitundu yosiyanasiyana komanso mawonekedwe apepala akatha kukonza kapena kusilira.
Mwachitsanzo, pazolinga zamalonda, mapepala oyambira otentha ndi mpukutu waukulu wa pepala lotenthetsera pambuyo pokonza zokutira, zomwe zimatha kukumana ndi kutentha (madigiri oposa 60), ndipo zitha kudulidwa mu pepala la fax, pepala lolembetsa ndalama, ndalama zafoni, etc. Kwa fakitale yopangira mapepala otenthetsera, mapepala opangira mafuta amagwiritsidwa ntchito popaka pepala lopaka kutentha, lomwe limapangidwa ndi fakitale ya mapepala ndipo ilibe ntchito ya mtundu wa tsitsi. Pokhapokha pambuyo pokonza zokutira zimatha kukhala mpukutu waukulu wa pepala lotentha ndi ntchito yamtundu wa tsitsi.
IV. Chidule
Pepala loyambira limatanthawuza pepala losakonzedwa, lomwe lingagawidwe kukhala pepala lazamkati lamatabwa ndi pepala lotayirira molingana ndi zida zosiyanasiyana. Mitundu yosiyanasiyana ya mapepala oyambira amagwiritsidwa ntchito m'magawo osiyanasiyana ndikugwiritsa ntchito, kupereka mapepala osankhidwa bwino amitundu yonse.
