Ma board a Melamine

Ma board a nkhope ya melamine amapangidwa ndi particle board,MDF, bolodi ndi plywood zomwe zimagwirizanitsidwa pamodzi ndi pamwamba.Zovala zapamtunda zimakhala makamaka zapakhomo komanso zochokera kunja kwa melamine .Chifukwa cha kukana kwawo moto, kukana kuvala, komanso kuthirira madzi, kugwiritsa ntchito kwake kumakhala kofanana ndi kuyika pansi kwa matabwa.

Bolodi ya melamine yomwe ndi bolodi yopangidwa yokhala ndi pepala lomatira la melamine lopangidwa ndi pepala.Ndi bolodi yokongoletsera yopangidwa ndi kuviika pepala ndi mitundu yosiyanasiyana kapena mawonekedwe mu zomatira za melamine resin, kuyanika kumlingo wina wochiritsa, ndikuyika pamwamba pa bolodi la tinthu, bolodi lamkati lamkati, plywood, blockboard, bolodi lamitundu yambiri. , kapena zina zolimba fiberboard, pambuyo kukanikiza otentha.Popanga, nthawi zambiri amapangidwa ndi mapepala angapo, ndipo kuchuluka kwake kumadalira cholinga.

Zilowerereni pepala lokongoletsera mu njira ya melamine ndikuyiyika pa iyo kudzera mu kukanikiza kotentha.Chifukwa chake, bolodi loletsa chinyezi lomwe limagwiritsidwa ntchito pamipando nthawi zambiri limatchedwa melamine-proof board.Melamine formaldehyde resin ndi yankho lokhala ndi zinthu zotsika kwambiri za formaldehyde, zomwe ndizogwirizana ndi chilengedwe.Njira iyi yomamatira sikuti imayambitsa kuipitsa kwachiwiri, komanso imachepetsanso kutulutsidwa kwa gawo lapansi mkati.Njira yochiritsirayi yadziwika ndi anthu ambiri ndipo imachitika motere.

Njira yomwe imagwiritsidwa ntchito kwambiri popangira ma melamine veneers ndiyo kukakamiza kotentha.Komabe, tisaiwale kuti pa kutentha kukanikiza mankhwala, pali zinthu zitatu processing zimene zidzakhudza zotsatira zake komaliza.Zinthu zitatuzi ndi nthawi ya kukanikiza kotentha, kutentha kwa kukanikiza kotentha, ndi kukakamiza koyenera.

Zinthu Zitatu za Njira Yopopera Yotentha yaMelamineMapepala

Hot kukanikiza nthawi: Kutalika kwake kumadalira kuchuluka kwa machiritso ndi kutentha kwa kutentha kwa melamine resin, kawirikawiri mkati mwa masekondi 40-50.Nthawi yayitali imatha kuyambitsa kuchiritsa kwa utomoni wambiri, kutayika kwa elasticity, komanso kuyambitsa ming'alu kapena kupsinjika kwamkati mwazinthu zomwe zimapangitsa kuti pakhale ming'alu ndi kupindika pakukonza kotsatira.Ngati nthawiyo ndi yaifupi kwambiri ndipo kuchiritsa kwa utomoni sikukwanira, ndikosavuta kupanga chodabwitsa cha bolodi lomatira, ndipo zimakhudza magwiridwe antchito amthupi ndi mankhwala amtundu wa chinthucho, zomwe zimakhudza kulimba kwa chinthucho.

Kutentha kwa kutentha:makamaka amatenga gawo lothandizira pakupanga mankhwala a melamine utomoni, mwachitsanzo, imathandizira kuchiritsa.Malinga ndi zofunikira zenizeni zopanga komanso zomwe wolembayo adakumana nazo, kutentha kwa mbale yosindikizira ndi koyenera kwambiri pa 145-165 ℃.Kutentha kwakukulu kumathandizira kutsitsa pambuyo pa kukanikiza, ndipo kumatha kufupikitsa nthawi yotentha ndikuwonjezera kupanga.Komabe, kutentha kwakukulu kumalepheretsa kuti utomoni usasunthike komanso kulimba, zomwe zimapangitsa kuti pakhale ma pores ang'onoang'ono pamwamba pa bolodi.

Akukakamizidwa koyenera: Ikhoza kutsimikizira kuphatikiza kwabwino pakati pa gawo lapansi ndi pepala la melamine.Pansi pa kutentha koyenera ndi kupanikizika, utomoni mu pepala la melamine umasungunuka ndi kukhazikika, kupanga malo otsekedwa ndi wandiweyani.Ikhozanso kudzaza ma pores osakhazikika pamtunda wapansi panthaka.Pamene kupanikizika nthawi zambiri kumakhala 2.0-3.0MPa, tikulimbikitsidwa kugwiritsa ntchito kupanikizika kochepa momwe mungathere popanda kukhudza khalidwe lazogulitsa, zomwe zimakhala zopindulitsa pa moyo wautumiki wa zipangizo, mafuta a hydraulic, ndi mkati mwa gawo lapansi.Koma kutsika kotsika kwambiri kumakhudza mphamvu yolumikizirana komanso kuthekera koyenda kwa utomoni pakati pa gawo lapansi ndi pepala la melamine.

Zolemba:

Melamine “ndi imodzi mwa zomatira za utomoni zomwe zimagwiritsidwa ntchito popanga bolodi lamtunduwu.Mapepala okhala ndi mitundu yosiyanasiyana kapena mawonekedwe amawaviikidwa mu utomoni, wouma mpaka kuchiritsa, kenako amayikidwa pamwamba pa bolodi la tinthu tating'onoting'ono, kachulukidwe kakang'ono ka fiberboard, bolodi ndi plywood.Ndi bolodi yokongoletsera yopangidwa ndi kukanikiza kotentha, ndipo dzina lodziwika bwino ndi melamine yomatira filimu yomata pepala lopanga kupanga, Kutcha bolodi lake la melamine kwenikweni ndi gawo lazokongoletsa zake.Nthawi zambiri amapangidwa ndi mapepala apamwamba, mapepala okongoletsera, mapepala ophimba, ndi mapepala apansi.

1.) Pepala lapamwamba limayikidwa pamwamba pa bolodi lokongoletsera kuti liteteze mapepala okongoletsera, kupanga pamwamba pa bolodi momveka bwino pambuyo potentha ndi kupanikizika.Pamwamba pa bolodi ndi lolimba komanso losavala, ndipo pepala lamtundu uwu limafuna kugwira ntchito bwino kwa madzi, koyera ndi koyera, komanso kuwonekera pambuyo pa kumizidwa.

2.) Mapepala okongoletsera, omwe amadziwikanso kuti pepala lamatabwa.Ili ndi mtundu woyambira kapena wopanda mtundu, ndipo imasindikizidwa mumitundu yosiyanasiyana yamapepala okongoletsa.Zimayikidwa pansi pa pepala pamwamba, makamaka pofuna kukongoletsa.Chigawo ichi chimafuna pepala kuti likhale ndi mphamvu zophimba bwino, kulowetsa, ndi ntchito yosindikiza.

3.) Pepala lakuphimba, lomwe limadziwikanso kuti titaniyamu yoyera, nthawi zambiri limayikidwa pansi pa pepala lokongoletsera popanga mapanelo okongoletsa amitundu yopepuka kuti ateteze wosanjikiza wapansi wa utomoni wa phenolic kulowa pamwamba.Ntchito yake yayikulu ndikuphimba mawanga amtundu pamtunda wapansi panthaka.Chifukwa chake, kufalitsa kwabwino kumafunika.Pamwambapa mitundu itatu ya pepala ndi motero impregnated ndi melamine utomoni.

4.) Mapepala osanjikiza pansi ndi maziko a matabwa okongoletsera, omwe amagwira ntchito yamakina pa bolodi.Izo zoviikidwa mu phenolic utomoni zomatira ndi zouma.Pakupanga, zigawo zingapo zimatha kutsimikiziridwa malinga ndi cholinga kapena makulidwe a bolodi lokongoletsera.Posankha mipando yamtundu uwu, kuwonjezera pa kukhutiritsa mtundu ndi mawonekedwe, mawonekedwe a mawonekedwe amathanso kusiyanitsidwa ndi zinthu zingapo.Kaya pali madontho, zokopa, zopindika, pores, mtundu wa yunifolomu ndi kuwala, kaya pali thovu, komanso ngati pali misozi ya pepala kapena zolakwika.

Ndi matabwa angati a melamine?

Melamine yoyang'anizana ndi particle board

Melamine amakumana ndi MDF

Melamine amakumana ndi plywood

Melamine yokongoletsera board:

1. Ikhoza kutsanzira momasuka machitidwe osiyanasiyana ndi mitundu yowala, ndikugwiritsidwa ntchito ngati ma veneers a matabwa osiyanasiyana opangira .Ili ndi kuuma kwakukulu, kukana kuvala, komanso kukana kutentha kwabwino.

2. Imakhala ndi mphamvu yokana mankhwala ndipo imatha kukana kuphulika kwa zosungunulira monga ma acid, alkalis, mafuta, ndi mowa.

3. Pamwamba pake ndi yosalala komanso yosavuta kusamalira ndi kuyeretsa.Melamine board ili ndi zinthu zabwino kwambiri zomwe sizingaphatikizidwe ndi matabwa achilengedwe, choncho nthawi zambiri amagwiritsidwa ntchito m'nyumba zamkati komanso kukongoletsa mipando ndi makabati osiyanasiyana.

Melamine board ndi zinthu zokongoletsera khoma.Common specifications: 2440mm × 1220mm, makulidwe 8mm -25mm.

Ubwino ndi kuipa:

Ubwino wamelamine anakumanabolodindi: pamwamba lathyathyathya, mapindikidwe pang'ono chifukwa cha coefficient chomwecho cha kukulitsa mbali zonse za bolodi, kuwala mtundu, kwambiri kuvala zosagwira pamwamba, kukana dzimbiri, ndi mtengo wachuma.

Choyipa cha bolodi lamtunduwu ndikuti chimakhala chophwanyika m'mphepete panthawi yosindikiza m'mphepete, ndipo chimangosindikizidwa molunjika popanda nsonga zakuthwa.
