Uyenza njani iMelamine yePlywood?

Inkqubo yokwenza i-laminating plywood nge-melamine yindlela ebalulekileyo yokwenza i-plywood iguqule i-plywood eqhelekileyo ibe yinto ehlala ixesha elide kunye ne-aesthetically ekholekileyo. I-Melamine Plywood idibanisa amandla okwakhiwa kweplywood kunye neempawu zokuhombisa kunye nezikhuselayo ze-melamine resin, ukudala imveliso eguquguqukayo esetyenziswa ngokubanzi kwimveliso yefenitshala, ukwenza ikhabhinethi, kunye noyilo lwangaphakathi. Inkqubo yokuthambisa ibandakanya ukudibanisa ngononophelo amaphepha afakwe kwi-melamine kwi-plywood substrates phantsi kobushushu obuchanekileyo kunye neemeko zoxinzelelo, okukhokelela kumhlaba okwaziyo ukufuma, ukuxhathisa, kwaye kulula ukuwucoca.

Izinto eziBalulekileyo kunye neZixhobo zeMelamine Lamination

Ukukhethwa kwezinto ezikrwada

Isiseko somgangatho ophezulu we-Melamine Plywood siqala ngokukhetha ngokucophelela izinto eziphathekayo. Isiseko seplywood kufuneka sikhethwe ngononophelo, ngokuqhelekileyo kusetyenziswa iinkuni eziqinileyo okanye ezixubeneyo zokhuni oluqinileyo kunye neziphene ezincinci kunye nomxholo wokufuma ozinzileyo phakathi kwe-8-12%. Amaphepha e-melamine afakwe kwi-lamination kufuneka ahlangabezane neemfuno ezithile zobugcisa, kubandakanywa umxholo we-resin efanelekileyo (ngokuqhelekileyo i-55-65%), ubunzima besiseko esilawulwayo (80-120 g/m²), kunye neepateni zokuhombisa ezifanelekileyo. Ulawulo lomgangatho kwesi sigaba lubandakanya ukuhlolwa ngokucokisekileyo kwezinto ezikrwada, ukuvavanywa kokunyakama kwe-plywood cores, kunye nokuqinisekiswa kweenkcukacha zephepha le-melamine ukuze kuqinisekiswe ukuhlangana okukuko kunye nomgangatho wokugqitywa komphezulu.

Iimfuno zezixhobo

Ukuveliswa kwe I-Melamine Plywood ifuna oomatshini abaphucukileyo kunye neenkqubo zolawulo ezichanekileyo. Izixhobo eziphambili ziquka oomatshini bokushicilela abashushu abakwaziyo ukugcina ubushushu phakathi kwe-160-180 ° C kunye namanqanaba oxinzelelo lwe-15-25 kg / cm². Izixhobo ezongezelelweyo ezibalulekileyo zibandakanya ukusasaza oomatshini kwi-uniform glue application, iinkqubo zokupholisa zokulawula ubushushu, kunye neenkqubo zokuphatha ezizenzekelayo zokuhamba kakuhle kwezinto. Izixhobo zale mihla zihlala zibandakanya iinkqubo ezilawulwa yikhompyuter ezibeka iliso kwaye zihlengahlengise iiparamitha ezicinezelayo ngexesha lokwenyani, ziqinisekisa umgangatho wemveliso ongaguqukiyo kuyo yonke imveliso eqhutywayo.

Ulawulo lokusingqongileyo

Imiba yokusingqongileyo ichaphazela kakhulu inkqubo yokulatyulwa kweMelamine Plywood. Indawo yemveliso kufuneka igcine ubushushu obuzinzileyo (20-25°C) kunye nokufuma (45-55% RH) iimeko. Iinkqubo ezifanelekileyo zokungenisa umoya ziyimfuneko ukuze kususwe ukukhutshwa kwe-formaldehyde kunye nezinye izinto eziphilayo eziguquguqukayo. Iinkqubo zokulawula uthuli zinceda ukugcina iimeko zokusebenza ezicocekileyo kunye nokuthintela ukungcoliseka komhlaba okunokuchaphazela umgangatho wokudibanisa. Izixhobo zokubeka iliso kokusingqongileyo kunye neeprothokholi zokuvavanya rhoqo ziqinisekisa ukuthotyelwa kwemigangatho yamazwe ngamazwe kunye neemeko ezifanelekileyo zokuvelisa.

Amanyathelo eNkqubo yokuVelisa

Ukulungiselela umphezulu

Isigaba sokulungiswa komphezulu sibaluleke kakhulu ekufezekiseni ukudibanisa okuphezulu kwimveliso ye-Melamine Plywood. Le nkqubo iqala ngokucoca ngokucokisekileyo imiphezulu yeplywood usebenzisa umoya oxinzelelweyo okanye iinkqubo zokufunxa ukususa uthuli kunye nenkunkuma. Ukuthanjiswa kwesanti kumphezulu kwenziwa kusetyenziswa iisanders zefektri ezinegrit progression efanelekileyo (ngokuqhelekileyo i-120-180-220) ukuphumeza uburhabaxa obuphezulu bomphezulu. Amanyathelo olawulo lomgangatho aquka ukuvavanywa koburhabaxa bomphezulu, ukuhlolwa kokucoceka, kunye nokuqinisekiswa kobumanzi ngaphambi kokudlulela kwinqanaba elilandelayo lemveliso.

Isicelo sokubambelela

Inkqubo yokuncamathelisa isicelo I-Melamine Plywood kufuna ulawulo oluchanekileyo kunye nobuchule obukhethekileyo. I-Urea-formaldehyde okanye i-melamine-urea-formaldehyde resins ziqhele ukusetyenziswa, kunye namazinga okuncamathelisa okusasazeka alawulwa ngononophelo phakathi kwe-150-200 g/m². Umxube weglue kufuneka uqulunqwe ngokufanelekileyo kunye ne-hardeners efanelekileyo kunye ne-catalysts ukufezekisa iimpawu zokuphilisa ezona ziphumo. Oomatshini bokusasaza abaphezulu baqinisekisa ukuhanjiswa kwe-adhesive efanayo, ngelixa iinkqubo ezizenzekelayo zijonga i-viscosity, ubushushu, kunye nobomi bembiza yomxube wokunamathela kuyo yonke inkqubo yokuvelisa.

Ukucofa kunye nokunyangwa

Inqanaba loxinzelelo kunye nokunyanga limele elona nqanaba libaluleke kakhulu kwimveliso yeMelamine Plywood. Iifowuni zomjikelo omfutshane zisebenza kumaqondo obushushu phakathi kwe-160-180 ° C kunye nolawulo oluchanekileyo loxinzelelo (15-25 kg / cm²) ukulungiselela ukuxhamla ngokufanelekileyo. Imijikelezo yokucofa ngokuqhelekileyo isuka kwi-15-45 imizuzwana nge-millimeter yobukhulu bepaneli, kunye neeparitha ezithile ezihlengahlengisiweyo ngokusekelwe kwiimpawu eziphathekayo kunye neemeko zokusingqongileyo. Iinkqubo zokucinezela eziphucukileyo zibandakanya iindawo ezininzi zobushushu kunye nezinzwa zoxinzelelo ukuze kuqinisekiswe ukuhanjiswa kobushushu obufanayo kunye nokudibanisa okuhambelanayo kuwo wonke umhlaba wepaneli.

Ulawulo loMgangatho kunye noVavanyo

Uvavanyo lwePropati yoMzimba

Ukuqinisekiswa komgangatho weMelamine Plywood kubandakanya uvavanyo olubanzi lwepropathi ebonakalayo. Iimvavanyo eziqhelekileyo zibandakanya amandla okubopha (EN 314-1), ukuxhathisa komgangatho (EN 438-2), ukuchasana nokukrala (EN 438-2), kunye nokuchasana kwempembelelo. Iisampulu zivavanywa ngokungqongqo uzinzo lwe-dimensional, kubandakanywa ukudumba ubukhulu kunye novavanyo lokufunxa amanzi. Iilabhoratri zovavanyo zanamhlanje zisebenzisa izixhobo ezizenzekelayo kwimilinganiselo engaguqukiyo nechanekileyo, igcina iirekhodi ezineenkcukacha zokulandelela umgangatho kunye nokuphucula inkqubo.

Uvavanyo loMgangatho womphezulu

Uvavanyo lomgangatho womphezulu we I-Melamine Plywood kufuna zombini ukuhlolwa okubonakalayo kunye nohlalutyo lwezixhobo. Abahloli abaqeqeshiweyo bavavanya inkangeleko yomphezulu, ukuhambelana kombala, kunye nokulungelelaniswa kwepateni usebenzisa iimeko zokukhanya ezisemgangathweni. Imilinganiselo yeglosi yenziwa kusetyenziswa iiglossmeters ezilungisiweyo, ngelixa uhlalutyo lokuthungwa komphezulu lisebenzisa izixhobo eziphambili zeprofilometry. Iinkqubo zokubona iziphene ezibandakanya iikhamera ezinokulungiswa okuphezulu kunye nobukrelekrele bokwenziwa bunceda ukuchonga nokuhlela ukungafezeki komphezulu ngexesha lemveliso.

Uqinisekiso Lokuqina

Uvavanyo lwexesha elide luqinisekisa ukuba i-Melamine Plywood ihlangabezana neemfuno zokusebenza kwizicelo ezahlukeneyo. Uvavanyo lokwaluphala olukhawulezileyo luveza iisampulu kubushushu bebhayisikile kunye neemeko zokufuma ukuvavanya ukuzinza komda kunye nokuthembeka komphezulu. Uvavanyo lokumelana neekhemikhali lubandakanya ukuba sesichengeni kwiikhemikhali zasekhaya eziqhelekileyo kunye neearhente zokucoca. Uvavanyo lozinzo lwe-UV luvavanya ukukhawuleza kombala kunye nokuthotywa komphezulu phantsi kokuvezwa kokukhanya ixesha elide, kubaluleke ngakumbi kwizicelo zokuhombisa.

isiphelo

I-lamination ye-plywood nge-melamine imele inkqubo yokuvelisa eyinkimbinkimbi efuna ukuqwalaselwa ngokucophelela kwizinto eziphathekayo, izixhobo kunye nokulawula inkqubo. Ngokuphunyezwa ngokufanelekileyo kwezi nkqubo kunye nemilinganiselo yokulawula umgangatho, abavelisi banokusoloko bevelisa umgangatho ophezulu I-Melamine Plywood ehlangabezana nemigangatho yamazwe ngamazwe kunye neemfuno zabathengi.
