Sindikudziwa kuyambira liti, sikukhalanso kotchuka kupenta mapanelo amipando m'miyoyo yathu, koma kugwiritsa ntchito mapanelo omwe amayikidwa mwachindunji ndi pepala loyang'ana, lomwe ndi lokongola, lokongola, losavuta komanso lothandiza.
Melamine-impregnated pepala ndi nthumwi bolodi kumaliza zinthu. Dzina lake lonse ndi Melamine-Urea-Formaldehyde Impregnated Bond Paper, yomwe imadziwikanso kuti pepala la "melamine". Ndi pepala lomatira lomwe lili ndi utomoni wina komanso zinthu zosasunthika zomwe zimayikidwa ndi utomoni wa amino (melamine formaldehyde resin ndi urea-formaldehyde resin) ndikuwumitsa pang'ono. Ikhoza kumangirizidwa kwa wina ndi mzake kapena matabwa opangira pambuyo pa kukanikiza kotentha.
Gulu & Ubwino
Pepala lothira melamine lingagawidwe m'magulu awiri: pepala lapamwamba ndi pepala la pansi kutengera momwe zinthu zimagwiritsidwira ntchito. Pepala lapamwamba limagwira ntchito yokongoletsa pamwamba ndikuwongolera magwiridwe antchito a bolodi. Pepala losavuta ndi pepala losindikizidwa lokhala ndi mapangidwe osindikizidwa nthawi zambiri limagwiritsidwa ntchito. Ntchito ya pepala lapansi ndikulimbitsa magwiridwe antchito a bolodi ndikulimbitsa mphamvu yopindika ya bolodi. Nthawi zambiri limapangidwa ndi pepala lolimba bwino kapena pepala lotsika mtengo. Pepala lothira melamine limagwiritsidwa ntchito kwambiri m'makabati, m'mawodi, ndi m'ma veneer apansi a laminate.
Guluu wa melamine ndi utomoni wopangidwa ndi amino womwe uli ndi kuchuluka kwa formaldehyde. Panthawi yokonzekera guluu, wopanga impregnation ayenera kuyang'anira kuchuluka kwa formaldehyde yomwe imatulutsidwa mkati mwa miyezo ya dziko.
Zomwe zili mu melamine zimatsimikizira mtundu wa pepala loyang'ana la melamine. Zomwe zili pamwambazi, zimateteza bwino chinyezi ndi mildew. Mapepala apamwamba kwambiri okhala ndi melamine 100%, kutsatiridwa ndi 50%. Mapepala ambiri omwe aikidwa pakali pano amagwiritsa ntchito 50% melamine. Alumali moyo wa pepala koyera melamine impregnated akhoza kupitirira chaka 1, koma mtengo ndi apamwamba kuposa 50%. Pepala lopanda kanthu limayikidwa ndi melamine resin ndi zowonjezera kupanga pepala lopangidwa ndi melamine. Mapepala okhala ndi melamine ndi matabwa (kachulukidwe bolodi, particle board, plywood) amapanikizidwa ndi zitsulo pamakina otentha kuti akhale mapanelo okongoletsa.
Zojambulajambula
Pofuna kuwonetsetsa kuti pepala la filimu yomatira ndi lopangidwa bwino, mapepala apamwamba okongoletsera ayenera kugwiritsidwa ntchito. Ziribe kanthu kuti ndi pepala lotani, liyenera kulipenda ndi kuperekedwa lisanagwiritsidwe ntchito. Mapepala osayenerera sangathe kulowa mu mzere wopanga. Pa nthawi ya impregnation, opareshoniyo iyenera kuchitidwa mosamalitsa molingana ndi zofunikira za ndondomekoyi ndi kuyesa ndi kuyesa kuyenera kuchitidwa panthawi yake kuti zitsimikizire kuti kuchuluka kwa guluu ndi 120% ~ 160%, zomwe zimasokonekera ndi 5% ~ 8%, ndipo digiri yoyamba yochiritsa ndi ≤ 65%. The impregnated ndi zouma zomatira filimu pepala ayenera yomweyo wokutidwa mu pulasitiki filimu ndi losindikizidwa ndi tepi.
Njira yopangira ndi kupanga guluu → kukonzekera guluu (kuwonjezera chothandizira kuchiritsa, chothandizira kutulutsa, ndi zina zotero) → kulowetsedwa koyamba (urea-formaldehyde resin) → kuumitsa koyamba → kulowetsedwa kwachiwiri ( melamine formaldehyde resin ) → kuumitsa kwachiwiri → kuziziritsa ndi kudula.
Zizindikiro zazikulu
Pepala lopangidwa ndi melamine limayesedwa ndi kuchuluka kwa kulowetsedwa, zinthu zosasinthika, komanso digiri yochiritsira.
- Kuviika kuchuluka: Zomwe zili mu utomoni wolimba mu pepala lodzikongoletsera lodzikongoletsera, lofotokozedwa ngati peresenti (%).
- Zinthu zosasinthasintha: Zomwe zili ndi zinthu zosakhazikika (makamaka chinyezi ndi mamolekyu ena ang'onoang'ono) mu pepala lamafilimu okongoletsera, owonetsedwa ngati peresenti (%).
- Digiri yochiritsa isanakwane: Digiri yochiritsa ya utomoni mu pepala lokongoletsa lafilimu, lowonetsedwa mu kuchuluka (%).
Kugwiritsa ntchito
Pepala lopangidwa ndi melamine lili ndi zabwino zomwe mapepala ndi utoto zina zokongoletsera zilibe:
Ikhoza kukhala yosavuta kupanga mapanelo ochita kupanga, kuthetsa kufunikira kwa kupenta ndi kupukuta; kukulitsa mtengo wa mapanelo opangira, kukongoletsa mawonekedwe azinthu, ndikupereka mtengo wogwiritsa ntchito; kukulitsa katundu wakuthupi ndikukulitsa kuchuluka kwa ntchito.
Pamsika wamakono wapampando, mapanelo a melamine veneer akadali olamulira. Chifukwa cha kuchepa kwa matabwa a anthu komanso kuchuluka kwa kufunikira kwa anthu kufunafuna zinthu zamatabwa, pepala lopangidwa ndi melamine lidzakhalanso bwino m'zaka za zana la 21!
