Pepala laiwisi

Pepala lairi waiwisi ndi mtundu wa pepala lapadera la mafakitale, lomwe limakonzedwa ndi zopangira zamtundu wapamwamba kwambiri ndi titanium dioxide pansi pa ukadaulo wapadera. Nditasindikiza, kenako kuperekera melamine, kumachitika kwambiri ngati mapazi opangira nkhuni monga fiberboard, ndi plywood, ndi zina zoyambira. Pamwamba payenera kukhala yosalala ndipo ili ndi mayamwidwe abwino pa Melamine remin ndi inki ya madzi.

1. Mayamwidwe

Pepala lapansi liyenera kukhala lophatikizidwa ndi Melamine ukwati usanalamire. Pali masekondi ochepa omwe amalumikizana ndi Melamine remin polemba. Munthawi yochepa iyi, pepala lapansi limafunikira kuti muchotse bwino kuchuluka kwa utoto wotchulidwa, ndipo kuchuluka kwake kumakhala kolemera kangapo. Chifukwa chake pepala lapansi liyenera kukhala ndi chobowoleza komanso yunifolomu komanso yunifolomu. Kupanda kutero lidzakhudze kuthamanga kwa kuphatikizira, ndipo kungapangitse vuto laubwino pomamanja. Mayamidwe ndi chinthu chofunikira chofunikira.

Titha kusintha mayamwidwe pepala lam'munsi posankha zamkati zapamwamba komanso kukonza kupanga. Pulp Hardwood ndi omwe amakonda kupanga pepala lapansi. Chitsamba cholimba cha hardpwood chilibe nthawi yayitali komanso yunifolomu, ndipo ali ndi mphamvu yabwino, kukhazikika kwamphamvu, kukhazikika kwabwino, kuyeretsa kwakukulu. Sikuti kungotsimikizira kuyamwa bwino, komanso kumatsimikizira kukhazikika kwabwino, kufanana, kuwunika ndi kupatulidwa ndi pepala lapansi. Pakupanga, kusakaniza digiri, mtengo wa PH umakhala ndi mapepala oyamwa. Pansi pa malo ogwirizana ndi mphamvu, yesani kutsitsa digiri yosakanikirana, onetsetsani kuti pH yamtengo pakati pa 6.5 mpaka 7.5, ndikuwonjezera kutupira kwa ulusi wa zamkati. Kuphatikiza apo, kusamvana kwa pepala kumatha kutsitsidwa ndikuchepetsa kupsinjika, kusokonezeka kwapakati pa ukonde. Pulogalamu yofewa imatha kupanga pepala lamunsi yosindikiza ndi mayamwidwe. Mwa kutentha kwachangu kuti mupume patembere kumawonjezera mawonekedwe ndi kuvomerezedwa, komanso kukonza mayamwidwe pepala lam'mwamba.

Pepala lapansi limafunikira kukhala ndi mphamvu yabwino yonyowa. Panthawi yakuledzera, iyenera kukhala ndi kudziletsa komanso kuyanjana kwambiri, kuthana ndi mphamvu yakuonekayo, idutse pamakina ogwiritsira ntchito osapumira.

Momwemonso ndi mayamwidwe, mphamvu ya pepala lam'munda imagwirizana kwambiri ndi mitengo yamitengo ndi njira. Chovala chomangira champhamvu chimakhala ndi mphamvu, ndipo mphamvu zimatha kuchuluka pogwiritsa ntchito ukadaulo kuti musinthe mapepala oyambira. Kuphatikiza apo, kugwiritsa ntchito wothandizira kutsiriza kumatha kukonzanso index ya pepala lapansi. Koma wolimbitsa thupi kwambiri ali ndi ntchito yozizira, imatha kuchepetsa kufiyira kwa prfiber, motero kukhudza kuyamwa pepala. Ganizirani ubale pakati pa mayamwidwe ndi mphamvu, chifukwa chosavulaza kuyamwa, yesani kukonza ukadaulo wofala, ndikupeza mphamvu ya pepala.

3. Opachity

Mukamaliza kusindikiza ndi kulembetsa, gawo lapansi silinawoneke pomanga. Chifukwa chake pepala lapansi pamafunika mwayi wabwino. Pofuna kusindikizidwa bwino, kuyera kwa pepala la pansi kuyenera kukhala kupitirira 90%. Kuti tisinthe kuyera kwake ndi kosoweti, nthawi zambiri timakhala chodzaza choyera chapamwamba, monga Titanium dioxide, lithupone, potaziyamu Tinate ulusi. Koma wothandizira kwambiri ndi woyipa pakuyamwa papepala. Mayamwidwe amakhala bwino pomwe wothandizirayo amakhala wotsika, pomwe wothandizirayo ali wokwera kwambiri, mayamwidwe amachepa. Chifukwa chake, yesani kuonetsetsa kuyamwa kwa pepala, nyonga ndi Opacity pokonza njira yopangira.

4. Kusalala ndi kufanana

Kusala kwa pepala laiwisi laiwisi ndi chizindikiro chofunikira chomwe chingakhudze kusindikiza kwabwino, ndipo kufanana kwake kungakhudzenso mayape. Zizindikiro ziwirizi ziyenera kulipidwa kwambiri pakupanga pepala lapansi. Kusala kumatha kusintha ndikusintha makina, koma ayenera kudziwa kuyanjana ndi kuyamwa.

Kufanana kwa pepala lam'mbuyo kumakhudzana ndi zinthu zambiri. Fidpp yotalika yayitali imatanthawuza kufanana, ndipo tiyenera kuchepetsa kutalika kwake ndi kumenyedwa kwaulere. Mukadzaza nkhanu pa maukonde owuma, ziyenera kuchepetsa kuchuluka kwa chidwi ndikuwonetsetsa kuti kufalikira kwathunthu. Kuphatikiza apo, kugwiritsa ntchito mitundu mitundu yamitundu iyenera kukhala koyenera, yesani kupewa zoyipa papepala lam'munsi chifukwa cha ntchito yapamwamba.

M'mawu, zizindikiro zonse za pepala laiwisi ndi zoletsa komanso zomwe zimachitika. Pakati pa mbalame zamkati, othandizira ndi kupanga, tiyenera kuganizira zonse zomwe zimagwiritsidwa ntchito moyenera, moyenera bwino mapepala, pomwe akuwonetsa ziwonetsero zosiyanasiyana.

Clemehou FIMO yokongoletsa zinthu co., Ltd., amasankha pepala lalitali laiwisi, ndikutsimikizira kuti pepala losindikiza pepala ndi kugwiritsidwa ntchito kwa ma melamine osagwirizana ndi kusinthika. Mndandanda waukadaulo wa pepala laiwisi kuchokera ku FIMO Wordor ali ngati pansipa.
