Angazi kusukela nini, akusadumile ukupenda amaphaneli efenisha ezimpilweni zethu, kodwa ukusebenzisa amaphaneli anamathiselwe ngokuqondile ngephepha elibheke, elihle, elihle, elilula futhi elisebenzayo.
Iphepha elifakwe i-melamine liwumsebenzi wokuqedela webhodi elimele. Igama layo eliphelele yi-Melamine-Urea-Formaldehyde Impregnated Bond Paper, eyaziwa nangokuthi yiphepha le-melamine. Kuyiphepha elinamathelayo elinokuqukethwe okuthile kwe-resin kanye nokuqukethwe okuguquguqukayo okufakwe i-amino resin (i-melamine formaldehyde resin ne-urea-formaldehyde resin) futhi yomiswe ngezinga elithile. Inganamathiselwa komunye nomunye noma kumabhodi okwenziwa ngemuva kokucindezela okushisayo.
Ukwahlukanisa & Izinzuzo
Iphepha elifakwe i-melamine lingahlukaniswa ngezigaba ezimbili: iphepha eliphezulu nephepha elingaphansi ngokuya ngokusetshenziswa komkhiqizo. Iphepha eliphezulu lisebenza njengokuhlobisa ubuso kanye nokuthuthukisa ukusebenza kwebhodi. Iphepha elingenalutho nephepha eliphrintiwe elinamaphethini aphrintiwe ngokuvamile kusetshenziswa. Umsebenzi wephepha elingezansi ukuqinisa ukusebenza kobuso bebhodi nokulinganisela ukugoba kwebhodi. Ngokuvamile likhiqizwa ngephepha elilinganiselwe lekhwalithi ephansi noma iphepha elingenalutho elishibhile. Iphepha elifakwe i-melamine lisetshenziswa kabanzi emakhabetheni, emakhabetheni, nasezindlini zokubeka phansi ze-laminate.
I-Melamine glue iyinhlaka esekelwe kuma-amino equkethe inani elithile le-formaldehyde. Phakathi nenqubo yokulungiselela iglue, umenzi wokukhulelwa kufanele alawule inani le-formaldehyde elikhishwe ngaphakathi kwamazinga kazwelonke.
Okuqukethwe kwe-melamine kunquma ikhwalithi engagugi yephepha elibhekene ne-melamine. Uma okuqukethwe kuphezulu, kuba ngcono umphumela wokuvikela umswakama kanye nokuvikela isikhutha. Iphepha elifakwe iqophelo eliphezulu linokuqukethwe kwe-melamine okungu-100%, kulandele u-50%. Iningi lamaphepha afakiwe okwamanje asebenzisa okuqukethwe kwe-melamine okungu-50%. Impilo yeshelufu yephepha elihlanzekile le-melamine elifakwe emanzini ingaba ngaphezu konyaka ongu-1, kodwa izindleko zingaphezu kuka-50%. Iphepha lesisekelo elingenalutho lifakwe ne-melamine resin kanye nezithasiselo ukwenza iphepha elifakwe i-melamine. Iphepha namabhodi afakwe i-melamine (i-density board, i-particle board, i-plywood) acindezelwa ngokushisa ngamapuleti ensimbi emshinini oshisayo ukuze abe amaphaneli okuhlobisa.
Ubuciko
Ukuze kuqinisekiswe ikhwalithi yephepha lefilimu elinamathelayo elifakiwe, kufanele kusetshenziswe iphepha lesisekelo sokuhlobisa eliphezulu. Kungakhathaliseki ukuthi hlobo luni lwephepha, kufanele lihlolwe futhi liphasiswe ngaphambi kokuba lisetshenziswe. Iphepha elingafanelekile alikwazi ukungena emugqeni wokukhiqiza. Ngesikhathi senqubo yokufakelwa, ukusebenza kufanele kwenziwe ngokuqinile ngokuhambisana nezidingo zenqubo futhi ukusampula nokuhlolwa kufanele kwenziwe ngesikhathi esibekiwe ukuze kuqinisekiswe ukuthi inani leglue lingu-120% ~ 160%, okuqukethwe okuguquguqukayo kungu-5% ~ 8%, kanti i-pre-curing degree ≤ 65%. Iphepha lefilimu elihlanganisiwe nelomisiwe kufanele lihlanganiswe ngokushesha ngefilimu yepulasitiki futhi livalwe nge-tape.
Inqubo yokukhiqiza ukwenza iglue → ukulungiselela iglue (ukwengeza i-ejenti yokwelapha, i-ejenti yokukhulula, njll.) → ukufakelwa kokuqala (i-urea-formaldehyde resin) → ukomisa kokuqala → ukufakelwa kwesibili ( i-melamine formaldehyde resin ) → ukomisa kwesibili → ukupholisa nokusika.
Izinkomba ezibalulekile
Iphepha elifakwe i-melamine likalwa ngenani lokukhulelwa, okuqukethwe kwento eguquguqukayo, kanye neziqu zokwelashwa kwangaphambili.
- Inani lokucwilisa: Okuqukethwe kwe-resin eqinile ephepheni lefilimu elinamathelayo lokuhlobisa, elivezwe njengephesenti (%).
- Okuqukethwe kwento eguquguqukayo: Okuqukethwe kwento eguquguqukayo (ikakhulukazi umswakama namanye ama-molecule amancane) ephepheni lefilimu yokuhlobisa, evezwa njengephesenti (%).
- Idigri yokwelapha ngaphambilini: Izinga lokuphulukisa le-resin ephepheni lefilimu lokuhlobisa, elivezwe ngamaphesenti (%).
Umthelela wokusetshenziswa
Iphepha elifakwe i-melamine linezinzuzo amanye amaphepha okuhlobisa nopende abangenazo:
Ingenza kube lula inqubo yokukhiqiza yamaphaneli okwenziwa, iqede isidingo sokupenda isifutho nezinqubo zokuxubha; athuthukise inani lamaphaneli okwenziwa, enze ukubukeka kwezinto ezibonakalayo abe muhle, futhi anikeze inani lokusetshenziswa; thuthukisa izakhiwo zomzimba futhi wandise ububanzi bokusetshenziswa.
Emakethe yefenisha yephaneli yamanje, amaphaneli e-melamine veneer asabusa. Ngokushoda kwezinsiza zokhuni zabantu kanye nesidingo esikhulayo sokuphishekela abantu imikhiqizo yezinkuni, iphepha elifakwe i-melamine nalo lizothuthuka kangcono ekhulwini lama-21!
