Iphaneli ejongene ne-melamine ikwabizwa ngokuba yiphaneli ye-prelaminated enombala owahlukileyo okanye ukuthungwa. Iphepha elifakwe i-melamine ligaywe kwiipaneli ezisekelwe kwiplanga njenge-MDF, ibhodi yamasuntswana, i-plywood, ibhodi yebhloko, kwaye emva koko i-laminated kunye nobushushu obuphezulu kunye noxinzelelo oluphezulu. Umphezulu wephepha le-melamine awunokuphucula kuphela amandla ephaneli, ukuqina kunye nokuzinza komda, kodwa unokwenza umphezulu wayo ube neenzuzo zokuxhathisa ukunxiba, ukumelana nobushushu obuphezulu, ukuchasana nokungcoliseka, ukukhuselwa kwendalo, impilo kunye nokusebenza.
Inkqubo yeephaneli ezilungiselelwe kwangaphambili: ULungiselelo lwePaneli →Iiphaneli zokuCoca→Iphepha eliFakelwe iMelamine→Unyibilikiso→Coca kwakhona →uHlolo→uGcino. Ngaphambi kokuthambisa, kufuneka sikhethe iiphaneli ezikumgangatho ophezulu ezisekwe ngamaplanga kunye nephepha elifakwe i-melamine, kuphela izinto ezikrwada ezifanelekayo ezinokuthi zikhethelwe ukuveliswa.
Iphepha elifakwe ngaphakathi lifuna umxholo we-resin yi-130-150%, umxholo oguquguqukayo we-6-7%, i-pre curing degree ≦ 65%. Iphepha elifakwe iMelamine kufuneka libe kwimeko entle, kwaye lipakishwe ngefilimu ukuthintela ukufunxwa kokufuma. Kungcono ukuhlamba iilayile phambi kweenyanga ezi-3 emva kokuveliswa, kwaye zigcinwe kwindawo yokugcina impahla enobumanzi obuyi-60 + 5%, ubushushu obungama-20-25℃. Iipaneli ezithandwa kakhulu yi-fiber board, i-particle board kunye ne-plywood. Iimfuno zepaneli zomgangatho: 1) isanti yecala eliphindwe kabini, umphezulu ugudileyo kwaye uqaqambile, ubukhulu obufanayo, ukunyamezelana kobunzima 0.2mm. 2) imiphetho yebhodi ayichanekanga, ayityi, akukho ngcoliseko yeoli okanye amanzi. 3) umgangatho womswakama webhodi ulawulwa kwi-6-10%.
Ngexesha lenkqubo yokuthambisa, kufuneka silandele ngokuthe ngqo inkcazo yobugcisa, ukulawula ubushushu obucinezelayo 140-190℃, uxinzelelo lweyunithi 2.0-3.0MPa, ixesha lokucinezela i-25-50s. Uxinzelelo lobushushu, uxinzelelo kunye nexesha lokucinezela zixhomekeke ngokufanayo kwaye zithintelwe ngokufanayo, ezinokuhlengahlengiswa ngokothando lwangempela lweendaba. Ubushushu obushushu bukukukhawulezisa ukusabela kweekhemikhali ze-melamine resin, olona bushushu busebenzayo yi-140-190℃. Ubushushu obuphezulu bunokunceda ukukhulula emva kokushicilela, kwaye kunokunciphisa ixesha lokushicilela, ukuphucula imveliso esebenzayo.Kodwa ubushushu obuphezulu kakhulu buya kwenza i-resin yokuphilisa phambi kokuhamba okufanayo, okubangela i-pore kumphezulu webhodi. Uxinzelelo olufanelekileyo lunokuqinisekisa ukunamathela okulungileyo phakathi kweebhodi kunye nephepha elifakwe ngaphakathi, uxinzelelo olusebenzayo luhlala luyi-2.0-3.0MPa, olulungele ukunyibilika kwe-resin kunye nokuqinisa, ukwenza indawo evaliweyo kunye ne-compact. Ngaphantsi kwesiseko somgangatho omhle, uxinzelelo oluphantsi kufuneka lusetyenziswe ukwandisa ubomi benkonzo yesixhobo, kwaye kunenzuzo kwisakhiwo sangaphakathi seebhokhwe. Kodwa uxinzelelo oluphantsi kakhulu luya kuchaphazela amandla okunamathela kunye nomthamo wokuhamba kwe-resin. Ngokweentlobo ezahlukeneyo zeepaneli, uxinzelelo lweyunithi kufuneka luhlengahlengiswe nge-buffer mat. Ixesha elicinezelayo lixhomekeke kwisantya sokuphilisa i-resin kwiphepha elifakwe ngaphakathi kunye nokushisa okucinezelayo, kunye ne-25-50s iyona nto ingcono. Ixesha lide kakhulu liya kubangela i-resin ephilisa ngokugqithisileyo kwaye ilahlekelwe i-elastic, ekhokelela ekuqhekekeni okanye ngaphakathi kwinjongo kwaye kwinkqubo elandelayo iya kuzisa i-crack, warping. Ixesha lifutshane kakhulu, ukunyanga i-resin akwanelanga, yenza iibhodi zinamathele kwaye zichaphazele ukuqina kwemveliso.
Uhlalutyo lweziphene zomgangatho oqhelekileyo kunye nezizathu zeepaneli ezenziwe ngaphambili:
I-1) Indawo emhlophe, esona sizathu siphambili kukuhamba kakubi kwephepha elifakwe ngaphakathi okanye umxholo we-resin ongaphantsi. Izizathu zinokuba: akukho sanding kumphezulu webhodi okanye sanding hayi iyunifomu, apho ingxinano isezantsi, kubangele isixa esikhulu ukufunxa intlaka kule ndawo, kwaye azise ukuhamba kakubi resin ezibangela indawo emhlophe.Deep ukudakumba kwezinye iindawo, kwaye Uxinzelelo alwanelanga kwezi ndawo ngexesha lokucoca, kwaye uzise ukuhamba kakubi kwe-resin, emva koko kubangele indawo emhlophe. Ubushushu obuphezulu kakhulu, kunye noxinzelelo oluphantsi kakhulu, kunye nepleyiti yentsimbi engcolileyo inokuchaphazela ukuhamba kwe-resin, emva koko kubangele umonakalo omhlophe. kwiqondo lokushisa elahlukileyo kwindawo eyahlukileyo yepleyiti yentsimbi kwaye kubangele indawo emhlophe. Ukugcinwa kwexesha elingaphezulu lephepha le-melamine elimisiweyo, iqondo eliphezulu lokunyanga kwangaphambili, okanye ixabiso eliphantsi kakhulu le-PH kwiibhodi, liya kuchaphazela ukuhamba kwe-resin kwaye kubangele indawo emhlophe. Isiqulatho seresin ephezulu kakhulu kwiphepha elifakwe imelamine sinokuzisa amaqamza ngexesha lokwanyisa kwaye kubangele indawo emhlophe.
2) Indawo emanzi, ibhekiselele kumzila wamaza kumphezulu webhodi prelaminated, kwaye kukho iziphene ezicacileyo.Ezona zizathu ziphambili zezi: Umxholo oguquguqukayo ophezulu kwiphepha elifakwe phakathi okanye iphepha elifakwe ngaphakathi liba limanzi liya kubangela indawo emanzi ngexesha lokunyanyiswa. iqondo lokushisa elicinezelayo okanye ixesha lokudubula, kulula ukwenzeka indawo emanzi. Isiqulatho sokufuma esiphezulu kwiibhodi sikhokelela kwindawo emanzi ngexesha lokulanyiswa.
3) Ukuncamathela kwipleyiti yensimbi kubhekiselele kwintonga yebhodi ye-melamine enepleyiti yentsimbi ngexesha lokuthambisa. Ukuncamathela kancinci kuya kuchaphazela umgangatho womphezulu, ukuncamathela nzulu kuya kuchaphazela imveliso.Izizathu eziphambili zezi: umxholo we-resin ephezulu okanye ipleyiti yentsimbi engcolileyo, ekhokelela ekukhululweni okubi. Umxholo oguquguqukayo ophezulu wephepha elifakiweyo, ubushushu obuphantsi obuphantsi kunye nexesha elifutshane lokucinezela, okubangela ukuba i-resin inganyangeki ngokupheleleyo ekukhululweni okubi. Umonakalo kwi-mat obangela ubushushu obungafaniyo kwipleyiti yentsimbi izisa ukukhululwa kakubi. Isiqulatho sokufuma esiphezulu okanye ixabiso eliphezulu le-PH kwiibhodi lizisa ukukhululwa okubi.
4) Amaqamza, izizathu eziphambili: iqondo lobushushu eliphezulu kakhulu, ucinezelo ixesha elide lizisa idemix okanye amaqamza. Ukufuma okuphezulu kakhulu okanye kubhityile kakhulu kwiibhodi kunokuzisa i-demix okanye amaqamza ngexesha le-lamination.Uxinzelelo oluphantsi kakhulu olukhokelela kwi-demix okanye amaqamza.
5) Ukugoba ngesaphetha kubhekisa kumphezulu ongalinganiyo umphezulu okanye ukugoba okusikwayo ngenxa yokungafani kakuhle kwamandla enjongo yangaphakathi. Izizathu eziphambili zezi: Umahluko omkhulu ekucinezeleni ubushushu phakathi kwentsimbi ephezulu nesezantsi ibangela isantya esahlukileyo sokunyanga kwaye ikhokelele ekulweni. Iphepha elahlukileyo lemelamine emiliselweyo kuyo yomibini imiphezulu inokubangela ukugoba emva kokulanyiswa.
Ngamafutshane, kufuneka sikhethe iphepha eligqwesileyo eligqwesileyo kunye nephaneli esekwe ngamaplanga njengezinto eziluhlaza, kwaye sandise inkqubo yokuvelisa ngokwezixhobo ezahlukeneyo zokuvelisa, phantsi kwentsebenziswano yokusebenza kunye nokuhlola abantu, abanokuqinisekisa ukuzinza komgangatho wemveliso.
