1, chophimba chakumbuyo kapena chophimba chakumbuyo chosindikizira kumbuyo ndi chophimba choteteza kumbuyo kwa pepala loyambira kuti lisatulutse zinyalala, mutabwezeretsa chizindikirocho mozungulira chomangira chomangira ku pepala la pansi. Ntchito ina ndikupanga zigawo zingapo za zilembo. Ntchito yosindikiza kumbuyo ndikusindikiza chizindikiro cholembetsedwa cha wopanga kapena chitsanzo kumbuyo kwa pepala losungira kumbuyo, chomwe chimagwira ntchito yolengeza komanso yotsutsa zabodza.

2. Chophimba pamwamba chimagwiritsidwa ntchito kusintha mawonekedwe a pamwamba pa zinthu zomwe zili pamwamba. Mwachitsanzo, kuwongolera kupsinjika kwa pamwamba, kusintha mtundu, kuwonjezera gawo loteteza, kuti lizitha kulandira bwino inki komanso kusindikiza mosavuta, kupewa dothi, kuwonjezera mphamvu yomatira inki ndikuletsa cholinga chosindikiza zolemba ndi zolemba. Chophimba pamwamba chimagwiritsidwa ntchito makamaka pazinthu zosayamwa, monga zojambulazo za aluminiyamu, mapepala opangidwa ndi aluminiyamu ndi zinthu zosiyanasiyana za filimu.

3, pamwamba pake ndi zinthu zomwe zili pamwamba, kutsogolo kwake kuvomereza zolemba zosindikizidwa, kumbuyo kwake kuvomereza guluu ndipo pomaliza pake kuikidwa pa zinthu zomwe ziyenera kumamatidwa. Kawirikawiri, zinthu zonse zosinthika zitha kugwiritsidwa ntchito ngati nsalu zomatira zokha, monga mapepala omwe amagwiritsidwa ntchito nthawi zambiri, filimu, zojambulazo zophatikizika, nsalu zamitundu yonse, mapepala achitsulo owonda ndi rabala, ndi zina zotero. Mtundu wa pamwamba pake umadalira njira yomaliza yogwiritsira ntchito ndi kusindikiza. Zinthu zomwe zili pamwamba pake ziyenera kukhala zokhoza kusintha kusindikiza ndi kusindikiza, kukhala ndi inki yabwino, komanso kukhala ndi mphamvu zokwanira zolandirira njira zosiyanasiyana, monga kudula die, kutulutsa zinyalala, kudula, kubowola ndi kulemba zilembo.

4, guluu womatira ndi njira yolumikizirana pakati pa zinthu zomatira ndi gawo lomatira, lomwe limagwira ntchito yomatira. Malinga ndi makhalidwe ake, lingagawidwe m'magulu awiri okhazikika komanso ochotseka. Limabwera m'njira zosiyanasiyana kuti ligwirizane ndi malo osiyanasiyana komanso nthawi zosiyanasiyana. Guluu womatira ndiye gawo lofunika kwambiri paukadaulo womatira wodzipangira komanso chinsinsi chaukadaulo wogwiritsa ntchito zilembo.

5, kumasula chophimba (chokutidwa ndi silicon layer) ndiko kuti, pamwamba pa pepala la pansi lokutidwa ndi silicone layer mafuta, lokutidwa ndi silicone mafuta lingapangitse pepala la pansi kukhala lotsika kwambiri pamwamba, losalala kwambiri, ntchito yake ndikuletsa chomangira chomatira pa pepala la pansi.

6, ntchito ya pepala la pansi ndikulandira chophimba chotulutsa, kuteteza guluu kumbuyo kwa zinthu za pamwamba, kuthandizira zinthu za pamwamba, kuti zikhale zodula, kutulutsa zinyalala ndi kulemba zilembo pa makina olembera.7, chophimba cha pansi ndi chofanana ndi chophimba cha pamwamba, koma chimakutidwa kumbuyo kwa zinthu za pamwamba, cholinga chachikulu cha chophimba cha pansi ndi:

(1) kuteteza zinthu pamwamba, kupewa kulowa kwa guluu.

(2) Wonjezerani kupepuka kwa nsalu;

(3) Wonjezerani mphamvu ya guluu pakati pa chinthu chomwecho pamwamba;

(4) Kuletsa pulasitiki yomwe ili pamwamba pa pulasitiki kuti isalowe mu guluu, zomwe zingakhudze momwe guluu limagwirira ntchito, zomwe zimapangitsa kuti mphamvu ya guluu ya chizindikirocho ichepe komanso kuti chizindikirocho chigwe.
